EPISTORE: Revolutionizing Green Energy with Ultra-Compact Hydrogen Power Solutions

Hydrogen is envisioned as the most promising green energy vector. By 2030, the European Commission proposes to produce 10 million tons of renewable hydrogen annually.
Solid oxide electrolysis and fuel cells are the most efficient technologies to deploy the hydrogen economy. These technologies have the capacity to produce hydrogen using renewable energy and to generate electricity from hydrogen.
However, conventional technology is impractical for certain applications due to weight and space constraints. EPISTORE addresses this issue through a miniaturised device, reducing its thickness by a thousand compared to conventional systems, while using a negligible amount of critical raw materials.
EPISTORE’s reversible cells operate in both electrolysis and fuel cell modes, offering 30 times higher hydrogen production per unit volume and 5 times greater power densities respectively.
This pocket-size device combines existing microelectronic manufacturing techniques for cost-effective production with novel thin film materials, enabling new scientific phenomena arising from the nanoscale.
These revolutionary Reversible Solid Oxide Cells allow for ultracompact and fast-response power-to-gas and power-to-power storage solutions directly connected to renewable energy sources and applicable to formerly forbidden scenarios such as off-shore power generation and new markets like transportation.
EPISTORE unlocks previously unexplored applications for renewable hydrogen, paving the way for a cleaner tomorrow.
