Concept
The Challenge
Europe must become climate-neutral, but one key element is still missing: affordable seasonal energy storage.
Europe has abundant renewable electricity in summer
but insufficient supply in winter.
Heat demand peaks when solar generation is at its lowest.
Existing long-duration storage options are inefficient, expensive,
or rely on carbon-based fuels.
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
Key Figures
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
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. .
