Gransolar To Produce Hydrogen From Seawater In Southern Spain

Last Updated on 08th January 2024

Spanish PV developer Gransolar plans to build a large-scale green hydrogen production plant in the southern Spanish port of Almería.


 According to a company spokesperson, the facility will generate hydrogen from seawater and will be powered by a 30 MW solar plant and a 20 MWh storage system with 4-hour autonomy. The facility will use a double-reverse osmosis system with energy recovery, followed by deionized water electrolysis via a proton exchange membrane (PEM). Additionally, cell membrane electrolysis can be used for secondary electrolysis of concentrated brine.


The main electrolyzer at the facility will have a capacity of 20 MW and a production capacity of 1,000 tonnes per year. The fuel produced will be stored in trucks for pressurized gas at a pressure of 400 bar.


The hydrogen will be used to power public transportation at the port as well as urban cleaning vehicles in Almería; it will also be used to power port unloading machines, national and international freight transport, and a portion of the local manufacturing industries' energy demand.


Almería isn't the only Andalusian port considering hydrogen production. Malaga's port is also expected to accommodate the development of green hydrogen as part of a project that includes artificial intelligence.


The project will cost EUR 80.5 million to construct and be completed by the end of 2024. Gransolar confirms the Almería City Council's support and commitment, as well as numerous companies from various technical industries, without giving any additional details.
