Revolutionizing Renewable Energy Storage
The REVEAL project is set to transform the landscape of renewable energy storage. By leveraging innovative technologies, we aim to provide a sustainable, efficient, and cost-effective solution for long-term energy storage. Discover how our groundbreaking approach can pave the way for a climate-neutral Europe.
Current Challenges
Today, renewable electricity and heat can be produced at low costs. However, the challenge lies in storing this energy for long periods, especially across seasons. Existing technologies for long-term storage are either scarce or prohibitively expensive, limiting their widespread adoption.
Our Innovative Solutions
The REVEAL project addresses these challenges with a unique and game-changing solution. By converting aluminum oxide into aluminum metal (Power-to-Al), we can store renewable energy in an environmentally friendly manner. This stored energy can then be converted back into heat and electricity or hydrogen (Al-to-Energy) whenever needed.
Why is REVEAL a Game-Changer?
High Energy Density
Our solution offers an unmatched energy storage density of over 15 MWh/m³, significantly higher than current alternatives.
Cost-Effective
The cost of converting electricity into a storable form is attractively low, making it a viable option for widespread use.
Environmentally Friendly
Our process minimizes environmental impact, with no emissions during storage and conversion.
Safe and Easy Storage
Aluminum is easy to store and transport, without the need for pressurized or cooled containers.
How It Works
This ground-breaking technical solution will enable to store large amounts of energy with an unmatched energy storage density of over 15 MWh/m³ at an attractively low cost, without losses and with lower environmental impact than today's solutions. The easy transportable energy vector can be used for heat and electricity or hydrogen production wherever and whenever needed, in scalable units from few kW to the MW range.
This breakthrough high-density storage solution will enable to cover energy demands with flexibility also in small units and off-grid situations, and – above all – in seasons where the demand is much higher than local renewable production could possibly cover.
Therefore, with the emerging technology of carbon free reduction of aluminium oxide to aluminium in combination with the release of energy from an aluminium storage vector, this project will provide one of the missing pieces of the puzzle for a climate neutral Europe.

Aproach
The REVEAL project introduces a groundbreaking Power-to-X technology that leverages carbon-free aluminum electro-winning cells to convert renewable electricity into aluminum metal (Power-to-Al). This stored aluminum can then be converted back into heat, electricity, or hydrogen through a controlled oxidation process (Al-to-Energy).
Advantages:
High Energy Density: Provides a volumetric energy density of over 15 MWh/m³ in practical applications, far exceeding most comparable technologies.
Cost-Effective and Safe: Simplified storage and transportation, with no reliance on a carbon source, lead to lower costs and enhanced safety.
Environmentally Friendly: Eliminates combustion with air, producing zero NOx, VOC, CO, and CO₂ emissions.
