The GreenH2CY project will produce hydrogen from renewable energy for the transport sector, to refuel trucks and replace diesel vehicles. The project will include a refueling station and hydrogen storage facilities, which will allow the electrolyser that produces the hydrogen to be used flexibly and to be run during off-peak hours in the electricity market. The relative GHG emissions avoidance from the operation of the project over a ten year period will be 100% compared to the reference scenario.

Project Information


The GreenH2CY project is the first-of-its-kind in Cyprus and will serve as an important step towards establishing the hydrogen economy in the country. Cyprus is an isolated electricity network and lacks the necessary storage facilities or interconnections with other networks to store renewable lectricity, notably at times of low demand and high production. Currently, this excess electricity is curtailed and discarded. Flexible hydrogen production during those hours using an electrolyser which runs off the excess renewable electricity, combined with a hydrogen storage facility can provide an innovative solution to energy storage and distribution to address this challenge. The project will avoid 21 677 tonnes CO2 equivalent of greenhouse gas emissions during its first ten years of operation, attributed to the replacement of diesel fuel.

The GreenH2CY project includes the installation and operation of a 2 megawatt (MW) Proton Exchange Membrane (PEM) electrolyser, a hydrogen storage facility and a re-fuelling station, in the same location. The hydrogen production unit is expected to produce approximately 150 tonnes of hydrogen fuel per year, which is equivalent to 627 tonnes of diesel fuel per year. The water used in the electrolyser will be supplied from tertiary treatment of stewater from the Water Development Department of Larnaca, supporting a circular economy.

In view of achieving the EU’s climate neutrality objectives and moving away from the use of fossil fuels, the transport sector requires mid to longterm decarbonisation solutions. The green hydrogen fuel produced by the GreenH2CY project will be used in the mobility sector, specifically for light and eavy trucks of a large bakery chain. However, its use could be extended to any other vehicles engineered to use hydrogen fuel in order to replace ossil-fuels based vehicles.

Due to an abundance of renewable energy, there is significant potential to produce green hydrogen in large quantities to use in both the mobility/transport sector (e.g. coaches, buses, saloon cars) and in the maritime sector (ports and marinas). The pilot project will reate crucial understanding and experience in the generation, distribution and use of green hydrogen, thus contributing to the acceptance of hydrogen as a reliable and sustainable form of alternative fuel in Cyprus. Thanks to this learning, the project aims to scale-up production both at the project site and at other sites already identified.
