Elestor's Mission & Relevance

Imagine a world without polluting power plants, powered purely by clean electricity...

This world is closer than you think. The sun and the wind are powerful enough, and so are the technologies to harvest their energy. However, possibilities to store renewable energy (sustainably, cost-effectively) are lacking; Long-Duration Electricity Storage (LDES) is ‘’the missing link’’ in the energy transition.

It is Elestor’s mission to cut the cost of electricity storage. We develop large-scale, cost-effective H2-X storage technologies that are carbon neutral and durable, thereby unifying the interests of the planet, people, and business profitability.
