Thousands of fossil power plants are still in operation today – we want to turn them into storage systems for clean energy


E2S Power will offer a cost-effective and easy to operate solution for transforming fossil fuel power stations into thermal storage systems for renewable energy.

This ‘drop-in’ solution will be able to feed the plant’s turbo-generator sets – which remain in place – with steam at the exact same conditions and flow rates that the boiler would have provided. The modular design of our product allows for straightforward adaptation to a variety of power plant sizes and layouts. Our unique advantages over other thermal storage concepts are lower price and smaller footprint, enabled by a novel thermal storage material called Miscibility Gap Alloys.

I have to say that the E2S concept of storage in my opinion is one of the best ideas seen lately, especially because it is utilizing existing equipment, which would otherwise remain unused. And also the traveling wave idea is brilliant to control the output temperature with minimal loss and without any »active« equipment.
