Concept
Europe aims to become climate-neutral, yet a critical challenge remains: affordable seasonal energy storage. While renewable electricity is abundant in summer, energy supply drops in winter just as heat demand reaches its peak and solar generation is at its lowest.
Current long-duration storage solutions are often inefficient, costly, or dependent on carbon-based fuels, highlighting the need for new sustainable approaches to balance energy supply and demand throughout the year.
CO₂e avoided annually, equal to about 7% of total EU emissions
Combined heat and electricity for buildings affordable cost by 2030
Lower storage costs compared to Power-to-Methane solutions
Unlocking annual market potential and creating around 250,000 jobs in Europe
The REVEAL Solution
REVEAL introduces a new Power-to-X pathway: renewable electricity is converted into aluminium fuel via a carbon-free electrolysis process.
This aluminium is solid, safe, and transportable, and can be stored loss-free for months or seasons.
When needed, it is reconverted into heat, electricity, or hydrogen. The result is a circular, emission-free and highly scalable storage cycle.
Circular – alumina is fully recycled
into new fuel.
Scalable – from a few kW for homes
to MW for industry.
Emission-free – no CO₂, NOx
or other pollutants at point of use.
How It Works
CO₂-free electrolysis produces renewable aluminium fuel.
Solid aluminium stored without losses for months.
Low-temperature (water) or high-temperature (steam) route → hydrogen + heat.
Alumina recycled; impurities stabilized.
GOALS
IMPACT
REVEAL delivers a breakthrough in seasonal renewable storage. It enables Europe to rely on renewables all year round, cutting winter dependency on fossil fuels.
The technology supports buildings, industry, mobility and off-grid areas with affordable, safe and circular energy.
Beyond technical progress, it strengthens European energy security, reduces imports, and opens new market opportunities. .
