Renewable energy is the energy generated from natural resources on Earth that are neither limited or exhaustible, such as wind and sun. Thus, renewable energy is an alternative to conventional energy based on fossil fuels and is generally less harmful to the environment.
Some Sources of Renewable Energy
Solar energy is created by capturing sunlight's radiant energy and turning it into heat, electricity, or hot water. Photovoltaic (PV) systems utilize solar cells to convert direct sunlight into energy.
The significant advantage of solar energy is that it is functionally infinite. There is an infinite supply of solar energy with the technology to harvest it, making fossil fuels obsolete. Using solar energy instead of fossil fuels can also help improve public health and environmental conditions. In addition, solar energy has the potential to eliminate energy expenses in the long run, as well as decrease your energy bills in the short term. Many government, state, and local governments also provide rebates or tax credits to encourage investment in solar energy. To know more about Solar Energy, click here.
Although solar energy can save you money in the long term, it has a high upfront cost out of reach for most households. In addition, for personal houses, homeowners should also have enough sunlight and space to install their solar panels, restricting who can realistically adopt this technology on an individual level.
Wind farms use turbines to generate wind energy and convert it to electricity. There are many types of systems used to convert wind energy, and each one is unique. Commercial-grade wind-powered generating systems can power a wide range of organizations, while single-wind turbines are utilized to complement current energy organizations. Utility-scale wind farms, which are purchased on a contract or wholesale basis, are another option. Wind energy is technically a kind of solar energy. Wind is caused by temperature variations in the atmosphere and the rotation of the Earth, and the geography of the planet.
Wind energy is a clean energy source, which means it does not damage the environment in the same way other types of energy do. Wind energy does not emit carbon dioxide or any other hazardous pollutants that can degrade the environment or damage human health, such as smog, acid rain, or other heat-trapping gases. Investment in wind energy technology can also lead to new employment opportunities and job training, as farm turbines should be serviced and maintained to remain operational.
Wind farms are often constructed in rural or isolated locations, far from busy towns where electricity is most required. Wind energy must be transmitted through transition lines, which raises the cost. Even though wind turbines produce relatively little pollution, some cities are opposed to them because they dominate skylines and create noise. In addition, wind turbines can pose a danger to nearby animals, such as birds, who are occasionally killed when they collide with the turbine's arms while flying.
When it comes to hydroelectric power, most people think of dams. Pumped-storage hydropower is the process through which water flows through the turbines of a dam to generate energy. Run-of-river hydropower utilizes a canal to funnel water through rather than a dam to power it.
Hydroelectric power is very flexible since it can be generated utilizing both large-scale projects such as the Hoover Dam and small-scale projects such as underwater turbines and lower dams on rivers and streams. In addition, because hydroelectric power does not emit pollutants, it is a far more ecologically beneficial energy source for our environment.
The majority of hydroelectric power plants use more energy than they generate. To pump water, the storage systems may need to utilize fossil fuels. Although hydroelectric power does not contaminate the air, it disrupts rivers. It harms the animals that dwell in them by changing water levels, currents, and migratory routes for many fish and other freshwater ecosystems.
Geothermal heat is heat trapped under the Earth's crust due to the Earth's creation 4.5 billion years ago and radioactive decay. Large quantities of this heat can sometimes escape spontaneously, but only all at once, resulting in well-known phenomena like volcanic explosions and geysers. This heat can be collected and utilized to generate geothermal energy by utilizing steam generated by heated water pumping under the surface, which rises to the surface and can power a turbine.
Geothermal energy is not as common as other forms of renewable energy, but it has considerable energy supply potential. In addition, it has a little environmental impact because it can be constructed underground. As geothermal energy is replenished naturally, it is not in danger of depletion.
When it comes to the drawbacks of geothermal energy, the cost is a significant issue. Not only is the infrastructure expensive to construct, but it is also vulnerable to earthquakes in some parts of the world.
Is renewable energy capable of powering the future?
Renewable energy technologies already account for approximately 26% of total global power, and the International Energy Agency (IEA) predicts that this will rise to 30% by 2024. According to the IEA, by 2024, the world's renewable energy capacity will have increased by 1,200 GW, which is equivalent to the capacity of the whole United States.
Expert analysis indicates that a completely sustainable energy system can be achieved worldwide over the next 30 years; the difficult part is persuading countries to change their ways.
What is the significance of renewable energy in the future?
There are many reasons why renewable energy is critical for the future, particularly given the negative impact that fossil fuels have on our world. This includes, among other things, air and water pollution, habitat and wildlife loss, and greenhouse gas emissions that contribute to global warming. Here are a few examples of why renewable energy is so important:
Lowers air pollution: By lowering air pollution, renewable energy may help improve people's health worldwide. Air pollution is a significant environmental problem, particularly in metropolitan areas and developing countries, and the World Health Organization estimates that 7 million people die prematurely due to inhaling contaminated air each year.
Lowers the danger of floods and droughts: Using renewable energy can also lower the risk of floods and droughts throughout the world. For example, many gallons of water are required to operate power plants that burn fossil fuels, leading to droughts in many low-rainfall nations. In contrast, climate change induced by the combustion of fossil fuels produces greater rainfall in other areas, resulting in catastrophic floods.
Promotes local economies: The development of renewable energy technologies also contributes to creating new employment and financing for local economies. As a result, more employment in renewable energy is being generated every day, and they are only expected to grow more secure as technology advances.
Lower long-term costs: Clean energy sources are becoming more appealing investment possibilities than fossil fuels. With the growing popularity of renewable energy sources like solar and wind power, investment is low risk, even with hefty initial installation costs. They can effectively generate electricity "for free" for decades after installation.
A future powered by renewable energy will result in a more sustainable environment and help many local economies in ways that fossil fuels cannot.
What is the best future renewable energy source?
Solar energy and wind power, together with hydropower, are considered the greatest renewable energy sources for powering our future planet. They are the cleanest renewable resources and are ideal for household, industrial, and national grid uses.
They can offer limitless quantities of clean energy to the world, but they can also boost local economies. Wind power technology has already resulted in a significant rise in employment and helps to put money back into local communities, with additional jobs being generated with each installation.
Solar energy can benefit everyone who has sufficient space for PV panels, and it is much less intrusive than wind turbines. And, although initial installation prices can be high, they will start to fall as solar becomes more common.
Is it possible for the world to survive on 100% renewable energy in the future?
The world may survive on 100% renewable energy in the future, but this will not be without challenges. To read more about the challenges in renewable energy click here. Each nation will have to go through its transition phase, which will be relatively simple for some and more difficult for others. Others may be hesitant even to begin the transition if their economy is highly dependent on fossil fuels.
The world's future can be unpredictable, and it's impossible to tell if it's possible to live completely on renewable energy. Still, we can help make the planet a better place by switching our homes' electricity to renewable energy.
In the future, how efficient will renewable energy be?
Renewable energy efficiency is determined by how much energy can be generated in a given period and how much it costs to generate this energy. Despite the fact that all renewable energy technologies have high initial costs, the costs of generating energy are considerably lower than the costs of obtaining fossil fuels.
With the continuous advancement of renewable energy technology, this efficiency will only increase, bringing us closer to a bright future for renewable energy.
What are the future benefits and drawbacks of renewable energy?
Renewable energy technologies have an infinite supply — as long as we have the sun, wind, water, and natural heat, we have renewable energy technologies.
Reduced global warming impacts, such as floods, severe storms, droughts, and other extreme weather conditions.
Fewer air contaminants, which lead to improved respiratory health.
Reduced greenhouse gas emissions result in a more stable climate.
More employment for local areas.
More robust supply, which assists in the elimination of power outages.
Lower energy costs, particularly with renewable energy prices falling.
Expensive initial installation costs.
Intermittent - depending on the renewable energy source, they will not provide electricity 24 hours a day, seven days a week. Solar energy, for example, cannot be produced at night, and wind is not always powerful enough to spin a turbine.
More advancements in storage solutions are required - renewable energy storage can be costly, but this is expected to improve as technology advances.
Geographical constraints - some areas will be more suited to renewable energy sources than others.
What factors will influence the future of renewable energy?
The environmental advantages and the cost of transition are the two most important factors determining the future of renewable energy.
The benefits of renewable energy sources often exceed the drawbacks, yet the high initial costs frequently discourage people from investing. Luckily, as environmental problems become more generally recognized, renewable energy prices, including installation costs, are falling, providing greater incentive to switch to renewable energy sources.
So, what does the future of renewable energy hold?
Renewable energy is expected to grow in popularity over the next decade, attempting to minimize the impacts of climate change. This may take some time, but we will have to switch to renewable energy to fight against climate change and protect our environment.
Why is renewable energy the future?
Alternative energy sources emit much less Carbon dioxide than natural gas, coal, and other fossil fuels. Switching to renewable energy sources for electricity production will benefit the environment by delaying and reversing climate change.
Is renewable energy a good investment for business?
There are many benefits to investing in renewable energy sources for businesses, including increased marketing possibilities, fewer emissions, cheaper energy costs, and many more. Businesses must lead the way in becoming more sustainable by expanding their usage of renewable energy.

Energy is an important feature in the economic and political development of a country. In developed nations like the USA, energy expansion has now reached a point where renewable energy sources also play a large part in the production of electricity.
To meet the energy demands of the country, most production of renewable energy comes from fossil fuels and other non-renewable energy sources.
Around 25% of the world’s energy is generated with renewable energy resources- mainly solar, wind, hydropower, and in some cases, geothermal. It is one of the fastest-growing electricity sources.
Renewable energy is collected from resources that are abundantly available in the environment, like the sun or wind. There has been a growing interest in renewable energy production as fossil fuels are depleting. In most parts of the world, renewable energy has become a primary source of energy production.
Renewable energy is preferred as they produce fewer greenhouse gases than non-RE sources. There are several other advantages to renewable sources like lower carbon emissions, reduced air pollution, and other socioeconomic benefits.
However, unlike non-RE sources, there are challenges in renewable energy like economic, political and regulatory barriers, structural, social, and technical challenges which require advancement in technology, and a heavy investment with a proper understanding of obstacles it faces. Some obstacles are due to technology associated with renewable energy, whereas others are because of policies, marketplace, regulations, and infrastructure.
Impact of Covid-19
The Covid-19 pandemic has brought the world to a grinding halt. It has severely impacted individuals and businesses alike, with many of the latter being closed down permanently. Similarly, the pandemic has also impacted the expansion of clean energy systems by forcefully curbing any investments.
The technology and adoption of renewables have been making uneven but sure progress. The global pandemic has slowed down this development. According to International Energy Agency, the global share of electricity supply from renewables had reached 28% in 2020 from 26% in 2019, but the growth is expected to slow down further. The total energy supply is set to reduce by 13% from 2019. This substantial decline can be attributed to supply chain disruptions, lockdown, and emerging financial problems. Transport biofuel production and renewable heat consumption are projected to decline due to lower industrial activity.
Governments have an opportunity to promote and accelerate the use of clean energy by incentivizing building, technology, and infrastructure across the country. This would be crucial to rebuilding the economy, create jobs, and build efficiency.
Capital Costs and Investment
The most obvious challenge of widespread adoption of renewables is cost, predominantly infrastructure costs like building and installing solar and wind power plants. Although it is quite cheap to operate and maintain solar and wind power plants, installation becomes more and more expensive.
Over the last few years, even though the prices of installation of solar panels has fallen significantly, it remains higher than non-renewables. On average, a 2-kilowatt solar panel system costs $4,159 after tax credits, whereas the capital cost of a gas-fired power plant would cost lesser than that.
In the last two years, investment in renewables has increased, but that is only because the investments in fossil fuels have been rapidly falling. Clean energy investments still fall short of what is necessary to convert into a more sustainable future. To ensure continuous investment in sustainable energy, policymakers have to focus on short investment turnaround, focus on rapid environmental gains favoring cleaner energy generation.
Power on demand
One of the most significant challenges of renewables is the ability to provide power on demand. In the case of solar power, you only get energy during the day and only when it is sunny. As for wind energy, power is generated only when it is windy. There is an intermittent generation of power in renewables which wouldn’t be a problem if there were appropriate energy storage solutions. The biggest test in providing power on demand is storage. Even if homes, businesses, or states install wind energy systems or solar panels, storing the generated energy is still an unsolved issue.
Opponents of renewable energy highlight the reliability factor on solar and wind to augment support for coal, gas, and nuclear plants, which provide baseload power. This argument is used by lobbyists to drive out investment into renewables, thus becoming a barrier to widespread adoption of wind and solar energy.
Renewable energy plants have grids that require a large area of land. It can be unappealing to customers to switch to renewable energy sources as it is conditional depending on the size of the land. Not all states and regions are apt to build solar panels or have wind turbines as they are dependent on the geographical location. For example, building solar panels in California makes more sense than building them in New York as the former has an abundant supply of both sun and land.
Renewables operates on what is known as a decentralized model. In a decentralized power plant, small generating stations are spread across a larger area that works collectively to deliver power. In the case of coal, nuclear power, or natural gas, they are highly centralized and depend on fewer high output power plants.
Decentralized systems prove to be a problem for siting and transmission of energy created by solar or wind. Siting is needed to move blades or solar panels to large pieces of land. To do so requires to draw up contracts, negotiate, acquire permits, or build community relations; all of this can delay or kill a renewable project even before it begins.
Businesses can incur additional charges due to demand and delivery which seems like a significant challenge for them. Utility services apply these charges to recover costs of purchasing energy and maintaining power lines and energy lost in the transmission system. Moving power sources closer to your business will help you avoid such preventable expenses.
The next challenge to overcome in renewables is the transmission of generated electricity. Transmission means the transfer of electricity from where it is generated to where it is consumed. Most transmitters that exist in this day and age are built for coal and other fossil fuels and not renewables. To make things easier for transmission of clean energy, there needs to be a significant infrastructure and technological development, which cost a lot of money.
Making the economics work with financing and siting can prove costly for developers and customers alike.
Policies and Regulations
Unfortunately, the fossil fuel industry is backed by multi-billionaires who wield a considerable amount of political influence. This severely affects the chances of expansion for the renewable industry. Industry experts estimate that the USA spends upwards of $60 billion on subsidies for fossil fuels every year. The taxpayers have helped fund the industry’s research and development, drilling, mining, and generation of electricity. Renewables like wind and solar enjoy much lesser subsidies and political backing. The fossil fuel industry has used its enormous power to spread misinformation about climate change.
To increase public interest and investment in renewables, there need to be clear and concise legal procedures and regulatory policies. Having proper regulations in place creates a stable environment for investment and overcome hurdles and can anticipate the revenue streams. Large-scale renewable energy projects require a large amount of capital which is hindered by the failure of proper policies that fail to attract private players.

Earth has become increasingly warmer every year with rising temperatures. The burning of fossil fuels in the past 150 years for electricity, heat, transportation, and any other human activity has increased greenhouse emissions. Other natural resources are also rapidly depleting, thus giving us a cause of worry.
Several homeowners and mainly businesses are, therefore, turning to renewable energy sources to become self-sustainable and self-reliant. Costs of commercial electricity are rising day by day with no end in sight. By turning to green energy, businesses can reduce operational costs and reinvest that amount back into their businesses.
If your business uses electricity for lighting, HAVC, computing, or production, opting solar for businesses will significantly reduce the cost. Installing these solar panels and combining them with an appropriate energy storage system, your business can save up to 20 to 25% energy and move towards energy independence.
Eligibility for Going Solar
One of the major factors to consider when going solar is whether it makes sense for your business to do so. Apart from this, going solar would be ideal for organizations that:
Work in states like California, Hawaii, or any state that either has expensive energy or massive Federal incentives
Have enough land, rooftops, or parking lots adjoining their businesses where the solar panels can Be set up
Have prioritized sustainability
Have massive energy demands
Market themselves as an environmentally friendly business
Reasons to Use Solar Power for Businesses
Growing businesses opt for investing in commercial solar power mainly to aid in offsetting additional expenses. With the expansion of the business, electricity consumption will also increase. You can also time your roof repairs or new constructions to coincide with installing new solar panels. Transforming into a business that chooses to become carbon-neutral by utilizing solar energy will enhance your business image in the community.
Implementing commercial solar panels cuts down your energy consumption and helps increase your savings. Excess energy generated by these solar panels can be stored with the help of off-grid batteries. Solar energy has a major drawback. Your company won't be powered at night or in severe weather conditions as solar only works during the day. Solar energy cannot handle the sudden power surges required to handle heavy machinery. Businesses are then forced to purchase and use commercial electricity to manage these spikes. However, these spikes can prove to be expensive. Merging photovoltaic systems with storage solutions can ease these spikes. This is vital during the "shoulder" hours when the sudden surge spikes can lead to demand charges.
Benefits of Going Solar
Reduction in Costs
The single biggest advantage of going solar is a massive reduction in electricity bills. Locations where 'net metering' is available can become another source of revenue for your business as the excess power produced can be sold to your local utility. Businesses, and companies that rely on out of date energy sources like coal, could be paying 7 to 30 cents per kilowatt-hour (kWh), whereas those using solar energy were paying between 2 to 12 cents per kWh.
The benefits of switching to solar depend on several factors- locations, industry, and business size. The most advantageous enterprises would be the ones who have built an appropriately sized system to cover all energy requirements and enough power to fall back on during peak consumption hours.
Businesses can incur additional charges due to demand and delivery. Utility services apply these charges to recover costs of purchasing energy and maintaining power lines and energy lost in the transmission system. Moving power sources closer to your business will help you avoidsuch preventable expenses.
There are possibilities of ascension in solar energy projects. You can start with a smaller set of solar panels that would contribute to your daily energy needs and build it over time. You can always sell the excess energy produced to your local utility provider as a source of additional revenue.
Federal Tax Incentives
As of 2021, the investment tax credit (ITC) allows businesses to deduct 22 percent of the cost of installing solar energy systems from their federal tax with no cap on its value. These businesses are eligible for the tax incentive as long as they have their energy system. I'f youdon't have enough tax liability to claim the credit that year, the outstanding credits would roll over to the next year, so long the tax credit is in effect.
Like every other power source, solar has its limitations too. The infrastructure that can consume excess solar power is not yet up to the mark. Since solar is tied to the grid, they are interdependent. If the grid fails, solar goes down too. Therefore, it is important to add a microgrid to the energy system.
Adding a micro-grid detaches your business from the utility providers and makes it independent of their services. It makes your organization what is known as an 'energy island'. The existence of these energy islands only protects your enterprise from power cuts due to natural disasters or any physical or hacking attacks. Your energy islands may also provide electricity to your local community during emergencies.
Solar energy has a massive role to play in the future of sustainability and environmental protection. By converting your business into a solar-powered business, you ensure the protection of the environment and reduce your company's carbon footprint on the planet. Studies also indicate that using solar energy for a long time also reduces utility costs. You can then invest the saved amount back into your business to promote advancements and innovations.
Being a solar-powered business could be an alluring prospect for your potential business partners. Environment-inclined customers tend to turn to prefer "responsibly green" businesses, and these businesses also appease local and state regulators, governments, and hedge funds.
Lower Maintenance Cost
Another major reason solar power is beneficial for your business is low to zero maintenance of the installed solar panels. Agencies that provide solar panels offer a warranty of 20 to 25 years on them. Since solar panels have fewer movable parts, the chances of these parts disintegrating or rusting are highly unlikely as opposed to technology that relies on movable parts. Thus, switching to solar energy would be the appropriate step to take for your business.
Things to Keep in Mind when Switching to Solar
When investing in solar energy, there are a few imperatives that businesses must follow. No matter the size, your business must be located where there is adequate sunlight, a roof strong enough to sustain the panels, and be inclined to reduce the cost of all operations.
There are various simple 'do-it-'yourself' kits launched in the market to entice small business owners to try and build these solar systems themselves.
However, it is essential to work with a solar provider when installing solar panels to get the best outcome—as in any industrial field, consulting with a solar power expert would help you optimize costs and gain maximum benefits.
Points to Explore Before Going Solar
Amount of Electricity Consumed
There are two main points to ponder over; "enough for one day" and "future years to come”. You could either sell excess energy produced to your local electricity supplier, which would add to your savings, or it could be stored with the help of li-ion batteries and utilized in the time of little to no sunshine.
Financing Solar Power for Businesses
Commercial solar power providers offer multiple business plans that would be best suited to the scale of your business. You can choose the better alternative for your business depending on how much discretionary cash you have and your solar infrastructure size. The size of the infrastructure will also depend on whether you want to gain dramatic results in terms of cost-saving or opt for low-cost start-ups and gain a more extended return on investment.
Some enterprises buy solar equipment with cash or loans. This method would give you tax credits and incentives, thus offering you a higher return on investment (ROI).
Another direction you could choose is going into a Power Purchase Agreement (PPA) with a solar energy provider and purchasing electricity from them at a lesser commercial cost. In a PPA, the developer looks after designing, permissions, financing, and installing the system for a meager amount.
Details of your precise business requirements are vital to analyze the cost and time of ROI of the solar energy system. It would depend on the place you are at and the size of your system. To get these exact details, hire the best solar energy consultant for your exact needs.
Important Steps to Remember
Outline your goals for a stable, sustainable, and financially sound future. Make sure that going solar is beneficial for your business. Calculate whether your region's utility costs are higher and hurt your business financially; whether there is ample storage space around your business to keep all the equipment. And whether adopting a green profile improves your goodwill in your local community.
Collect data on your electricity usage of at least one year to analyze the operating cost, energy spikes, and consumption patterns. Calculating business losses will aid in understanding the need to switch to solar energy.
Tie up with a commercial solar specialist when making the switch to solar energy. Often, customers fail to recognize the importance of this step. Avoid contractors who set up solar panels as a side business as they would not understand the intricacies of the job. Check all the references before you partner up with a specialist.
Last thing to keep in mind is thatgetting a solutions provider would make things easier for you. The provider will take care of everything- designing the system, finances, grid connection, and system maintenance. Ensure that you have a provider with sound support and has a portfolio of proven experience in solar infrastructure per your business needs.

Cleaner energy resources are the dire need of the hour and this is a known fact. While scientists and experts across the planet are striving hard to reduce our reliance on fossil fuels, our energy needs have never faced a downfall- thanks to rapid industrialization and urbanization. Although renewable resources like solar, wind, and hydro-electric power are the most popular alternatives, these are seasonal energy sources and the energy production from the same will not be similar all around the year. The fluctuations in production hence cannot always meet the energy demand of the population, and this makes the renewable energy sources not completely reliable.
Solar Production v/s Demand of the same in a year
What and How H2 is produced?
Now, this is where Hydrogen- the first element of the periodic table comes to the spotlight with a solution. Being a gas, hydrogen fuel can very well cater to our energy needs and is produced from techniques including Thermochemical, Solar-Water splitting, electrolytic and biological processes. While the production of this cleaner energy source leaves a carbon footprint of about 830 million tonnes in the form of CO2 annually, the result being a zero-emission fuel is what makes H2’s future bright.
Storage of H2 – the million-dollar question:
Having almost cleared the need and methods of producing hydrogen fuel, we will be looking at an area that is usually not given much thought about and that is the storage of H2. As already mentioned, for time being let us consider hydrogen as an alternative to renewable resources which is utilized when the energy demand increases drastically. While producing the fuel in the nick of time is obviously undoable, sufficient storage of H2 anticipating the demand is the best choice. Like Natural Gas, Hydrogen is also compressed before storing to achieve lower volume and also because liquid hydrogen demands a 64% higher amount of energy for storage than its compressed gaseous counterpart.
Storage tanks v/s Geological landforms:
Compressed Hydrogen can be stored in surface storage vessels (like steel composite concrete vessels and in wind turbine towers) or in geological landforms like (salt caverns, depleted O&G reservoirs, and aquifers). Nevertheless, unlike the underground geological landforms which offer huge storage capacity owing to their sheer scale, the storage tanks which can range in size from a small bottle to a huge tank require high amounts of pressure to store an appreciable amount of H2 in it. Since these storage tanks are usually constructed on the surface, the pressure conditions in these tanks need to be artificially stimulated and thereby mount huge upfront costs when compared to their geological storage counterpart.
H2 storage prices in Geological Landforms v/s Storage Vessels (in $/kg)
The above is a table comparing the prices of Hydrogen storage in Geological landforms and Storage Vessels at different pressure conditions. It is visible from the table that it's about 218 times cheaper to store the same amount of hydrogen in Geological landforms than in storage vessels.
Is geological storage truly a better option?
Like any other storage option geological storage too has its pros and cons. From the erosion of pipelines to the tedious task of injecting the gas and maintaining it at apt pressure conditions, geological storage has its limitations. However, the important prerequisite is the availability of the suitable landform itself.
While most of the Depleted O&G Reservoirs have already met all the requirements for a suitable Underground Hydrogen Storage (UHS) system, the presence of unrecoverable remnant fluids in it makes it both a boon and a bane. This is because the presence of remnant fluids like oil and gas satisfies the cushion gas need for efficient storage of H2 in the reservoir, chances of contamination of H2 by the same is also high. This is the reason why Aquifers too aren’t favorable underground landforms when it comes to hydrogen storage.
Salt Caverns- the best UHS System?
The problem of Hydrogen contamination in Depleted Oil & Gas reservoirs and aquifers leaves us to the next big suitable subsurface landform- salt caverns. Unlike the other two landforms, the problem of contamination can be prevented in these dome-like structures formed due to the upliftment of salt deposits and it is also found that about 98% of its storage efficiency can be used to store Hydrogen here. The reason behind its relatively expensive nature when compared to its other two counterparts is due to the process of salt removing or leaching that must be done before storing to ensure that the contamination of the gas is unheard of at least here.
Suitable Conditions of UHS:
As per Stefan Iglauer, the maximum amount of H2 can be stored at a depth of 1100m beneath the Earth’s surface and the capacity gradually decreases up until 3700 m depth beyond which the wettability of the gas increases as it percolates through the rocks and hence cannot be permanently immobilized. Conclusively it is found that suitable landforms formed at 1km depth can store up to 2.0 Mt of H2. Comparing this 2 MT storage capacity of Salt Caverns with the currently available storage tanks which can store about 800 kg of H2 in it, it is visible that geological landforms have a clear upper hand at least when it comes to storage capacity.
Future of UHS:
With demands for Hydrogen fuel estimated to grow at 5.48 % annually and the need for a suitable storage system of the same at 5.8% annually, the field of Underground Hydrogen Storage systems indeed has a bright scope. Moreover, to meet the large-scale needs of Industries, there is an imminent need to level up the storage capacity of H2 and by exploring suitable geological landforms across the globe, the estimated industrial need of 1200 kT/ year in 2050 can be met.
