Imagine using wind power to split water into hydrogen gas, which acts like a giant battery for a whole island. This gas is stored and then used to power city buses or put electricity back into the grid when the wind isn't blowing. It's essentially a way to turn unpredictable weather into a steady stream of clean fuel and power.
Islands struggle with energy stability and high carbon emissions from transport and power grids. They lack the infrastructure to store excess renewable energy for long-term use.
A complete hydrogen value chain pilot including a 4 MWel electrolyser, high-pressure storage, a 0.4 MWel fuel cell, and hydrogen-powered buses.
If you are a city transport operator dealing with carbon emissions from diesel fleets — this project developed a system using hydrogen buses from Union Coaches-SOLMAR that run on clean fuel produced locally via a 4 MWel electrolyser.
If you are a utility provider dealing with electricity grid instability — this project developed a 0.4 MWel PEM Fuel Cell that stores energy as hydrogen and releases it back to the grid to balance supply.
If you are a port manager dealing with shipping fuel decarbonization — this project established a production hub at the port of Atherinolakkos that can provide hydrogen as a maritime fuel.
The system utilizes an Alkaline Electrolyser with a capacity of +3 MWel to +4 MWel, capable of producing over 500 tons of hydrogen per year.
Based on available project data, specific cost figures and pricing models are not provided, although Life Cycle Costing (LCC) studies are part of the project scope.
The project partners have signed a Consortium Agreement to secure cooperation and the operation of the pilot plant; however, specific IP licensing terms are not detailed in the summary.
It connects to the 582 MW Aegean wind project and the Greek-Egypt electricity transmission interconnection to utilize cheap African PV power.
The project period runs from June 1, 2023, to May 31, 2028.
The consortium is heavily industry-driven with a 70% industry ratio (7 out of 10 partners), indicating a strong focus on commercial viability over pure research. It includes specialized technology providers like De Nora and Ballard, alongside local implementers like EUNICE and Union Coaches-SOLMAR, spanning 4 countries (DK, EL, IT, NL).
