Outdated perceptions: how energy attitudes are damaging customer wallets

Article | July 7, 2023

Despite rising energy costs and dwindling customer ratings of the ‘Big Six’, over 37% of Brits still believe they are getting a good deal when it comes to gas and electricity. Here, Keith Bastian, CEO of rising independent Outfox the Market, challenges those age-old perceptions that are damaging consumer bank balances… I have never quite understood the notion of pay more for the same service. Except that last part, is really where the difference lies. As I have made my way through the energy market, it seems clear to me that we are facing a common notion. Age-old dinosaurs, that have relied on name status and brand power to retain customer loyalty, despite not providing anything different or any value-added service, give the impression that customers are somehow safer with them. That is the biggest misconception. We at Outfox the Market would like to challenge that. Of course, when I speak in such a way, I am referring to the ‘Big Six’, those long-established brands whose share in the energy market whilst substantial, is increasingly coming at the cost to its customers. For example, in the latest independent customer rankings from Which, it was determined that the traditional big energy companies had some of the lowest scores for customer service and value for money, yet some customers still feel secure with them. On the contrary, rising independents, such as ourselves, were scoring highly in these areas and this is where I feel the difference lies. Regardless of your opinion on fossil fuels and/or renewables, it is more the value of looking after your customers, understanding their concerns and dealing with them efficiently that has become somewhat lost for the ‘Big Six’. It is true that they have a larger proportion of customers to serve with a larger workforce, but that should not be to the detriment to the service they provide. What were are seeing now, as evidenced by the recent Ofgem price hikes, is the ‘Big Six’ once again failing consumers in these areas, with most of the top names putting costs up by £96 a year on average as of April. I am not one to not acknowledge that energy firms are tongue-tied in some respects in passing regulated costs on; there are times when we must. However, customers could also benefit from a little research. Even with growing numbers of consumers switching, nearly 60% of all households in the UK are still on standard variable rate tariffs, those that are subject to the incoming Ofgem hikes. So, the real question is why aren’t more customers switching? Heritage, loyalty and brand association. These facets really should not come at cost of paying more for energy. I really believe it is down to time-sensitivity and a misunderstanding around the barriers to switching, with cost somewhere in the middle. According to MoneySuperMarket, 75% of us would switch if we could save £149.99. A hefty figure, but why not the £96 highlighted earlier? That is still pretty good, and something that would add up nicely over the years. I understand we are time-poor as a nation, it’s well publicised, but we’re all well averse in switching phone contracts and insurance deals, so why not where our energy comes from? Truth be told, I believe it’s an age-old notion that energy is ‘just something that comes with the house, not worth the hours or hassle to change.’ But in all honesty, it takes a matter of seconds to switch. Firms such as ourselves offer this and more via a quick and easy quote online. Best of all, many energy providers will help manage the switching process for you, contacting your current provider and notifying them of your intentions. I would also like to challenge this notion that once an energy firm ‘gets you’, you are ‘locked in’ for years upon end in ever rising contract costs. If you are on a standard variable tariff, you can switch to a new provider at any time. What’s more, even if you are in a fixed term energy deal, which can be subject to exit fees, sometimes the cost involved outweighs the savings you can make with your new provider. Customers must do their best to ask more of energy firms, check the service they are being given and hold it up against national bill averages. Compare what your neighbours, friends and family are paying under similar living circumstances, and weigh up if you are being given a fair deal. Living costs and regulated price hikes are always going to be an ever present worry, so I call on both customers and energy firms to do their due diligence in these respects. Age-old energy firms relying on their reputation must take a serious inward look at their lessening market share to understand why they are failing customers. It’s time to make a change now, both from business attitude and a consumer standpoint; switching is quick, easy and a vital notion to bear in mind, as both retaining custom and saving money becomes an ever-growing sticking point in the energy market.

Article | July 15, 2022

While most businesses presently strive to achieve environmentally friendly operations and lower their carbon footprints, this argument might not sway all businesses or company executives. While using renewable energy sources or energy management systems has clear environmental benefits, businesses that want to improve their operations and decrease overhead expenses should also consider such technologies. A steady and high-quality power supply is required for the smooth running of any kind of industry. Energy management systems (EMS) are used by a variety of industries to provide a consistent and dependable supply of energy. Energy Management Systems: Advantages for a Business Businesses and industries that use energy management solutions often achieve considerably bigger savings than those that do not use such systems. EMS examines all of the company's processes and enhances them for energy savings. The savings realized by the usage of energy management systems have a direct influence on the bottom line. Some of the most significant benefits of energy management systems are listed below. Improved Brand Image Using energy management systems result in lower power usage and, as a consequence, more environmentally friendly operations. Process optimization is recognized by business clients, customers, and suppliers because it shows excellence in planning and management. Better Productivity and Competitive Edge Reducing energy consumption via process optimization and effective load planning not only increases the overall productivity of industrial operations but also helps businesses to catch up with their competitors through continual process development. Cost-Reduction Energy management systems can ensure at least a 20% decrease in energy bills.

How viable is Underground Hydrogen Storage?

Article | December 23, 2021

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.
