Affordably storage capacity is key to the success of renewable energy solutions: https://lnkd.in/eYnUKcUS

Batteries the size of supermarkets will help balance the emerging clean energy system, thus ensuring we have power even when there’s no sun or wind. This is how they work. #EnergyStorage #LDES #Hydrogen #EnergyTransition Elestor B.V.

"Flow batteries are considered one of the most economical options for long-duration energy storage. In an interview with Guido Dalessi, Elestor B.V., we will find out how the Dutch company uses innovative technologies to benefit from the synergy of electricity and hydrogen for its flow batteries." https://lnkd.in/eP726vPx #hydrogen #energystorage #LDES

Using stored H2 to mitigate solar and wind is not currently economically viable. When the intermittent power is cheap, the electrolysis capacity factor is low, so the CAPEX is unfavorable. When the capacity factor is high, the cost of energy is high, so the OPEX is unfavorable. Using electrolysis produced H2 for the production of steel, concrete, and chemical processes suffers from the same problem. This is the crux of intermittent grid - every downstream energy user inherits the low capacity factor. Improving electrolysis efficiency does not really solve this problem. #renewables #H2 #energy #green #electrolysis https://lnkd.in/gHaSaAbb

In a world moving toward renewable energy, traditional lithium-ion batteries aren’t enough. WPI researchers have introduced silicate to iron-based alkaline batteries to prevent hydrogen gas formation, creating a more efficient, cheaper battery option. 🔋 Iron is abundant, recyclable, and sustainable, making this silicate-boosted tech a serious contender for energy storage. The best part? It could revolutionize microgrids, solar, and wind power systems worldwide! 🌞🌍 https://lnkd.in/gieyea49 #EpiphanySolutions #BatteryTech #SustainableEnergy #IronBatteryRevolution #WPIInnovations #FutureOfPower #EcoFriendly #SilicateInnovation

Green hydrogen is produced through water electrolysis and the process is powered by renewable sources such as wind or solar energy. The process is multifaceted and can be categorized in four different types according to the experimental conditions.

Similar concept we are considering for energy storage for charging in rural areas.

Although #greenhydrogen is increasingly seen as a crucial energy carrier in future #zero-carbon energy systems, for a profitable exploitation of #electrolysers still high amounts of #subsidies are required. To what extent will this change in the future? In order to answer that question, one has to analyse the business case of electrolyzers within the context of internationally integrated #electricity and hydrogen markets. Afterall, green hydrogen is a tertiary energy carrier which is produced from the secondary energy carrier electricity. Arjen Veenstra and I have conducted this analysis in our paper which has just been published by @AppliedEnergy. In this paper, we analyse the profitability of electrolyzers plants in various future circumstances regarding electricity and hydrogen markets and future prices for natural gas and carbon. We find that in the current market circumstances, an investment in a 100 MW electrolyser plant needs almost all its investment costs subsidized in order to become break even, which is in line with current support schemes. The required subsidy declines when the supply of renewable electricity increases strongly as that results in much more hours with low electricity prices. However, when the increase in renewable electricity supply happens together with an increase in the (international) demand for electricity because of, for instance, the #electrification of heating and transport, the subsidy requirement for electrolysers remains high. After all, electrolysers have to compete with alternative usages of electricity. This shows that for a profitable exploitation of green hydrogen production, subsidies may be required for a long period of time.

Good read about the profitability of hydrogen.
