GreenGas Project
in Évora
FUSION-FUEL is developing its first utility scale demonstrator plant – the GreenGas project – in the Évora region of Portugal. The project is expected to go-live in the second quarter of 2021 and will be Portugal’s first large scale solar-to-hydrogen plant.
Évora is ideally located for FUSION-FUEL's technology, with high levels of solar irradiation, a closed-loop natural gas network, readily available land and good access roads and connections. The combination of these features make Évora a great location for FUSION-FUEL's first demonstrator facility.
Solar to Hydrogen
Power Plant

55 HEVO-SOLAR generators will be deployed in the GreenGas project across two phases. Once commissioned, the plant will produce nearly 70 tons of green hydrogen per year, representing an avoidance of over 600 tons of CO2 emissions annually versus conventional hydrogen production.

The hydrogen produced at Évora will be used to establish a track record in use-cases: hydrogen blending in the natural gas network, conversion into electrical energy via a fuel cell and fed into the electric grid during periods of peak demand, and compression and bottling for industrial applications.

This is a strategic project for both FUSION-FUEL and Portugal overall in light of Portugal’s National Hydrogen Strategy, as it will be the first large scale solar to green hydrogen project in Portugal and the first pilot for industrial scale blending of hydrogen into the local natural gas network.
GreenGas I
Consists of 15 HEVO-SOLAR generators with the latest generation of FUSION-FUEL's HEVO electrolyzer, which will also provide for the production of green hydrogen using renewable energy from outside sources in times of low or no solar irradiation. This phase will include the installation of a hydrogen storage system, as well as a fuel cell to generate electricity to be fed into the national grid.
Phase I will also seek to validate the HEVO’s solar-to-hydrogen conversion efficiency of 26.8% on an industrial scale.

GreenGas II
Consists of 40 HEVO-SOLAR generators which will produce approximately 35 tons of green hydrogen per year, using only solar radiation. A portion of the hydrogen produced will be injected into the local natural gas network to pilot hydrogen blending, and the remainder will be compressed and bottled for sale to industrial users.

This will be Portugal’s first large scale project to produce green hydrogen from solar energy and blend green hydrogen at scale into a local natural gas distribution network.
