It intends to build a £150 million (€170 million) green hydrogen plant at the port of Felixstowe, England.
The plant would initially feature 100MW of electrolysis capacity, which could be operational in 2026. But this could be expanded to a capacity in the multi-hundred megawatt range at an unspecified later date, an Iberdrola spokeswoman explained.
Iberdrola plans to use the green hydrogen – produced by splitting water into hydrogen and oxygen using electricity produced by renewable sources – to power vehicles and machinery at the port. It also plans to use the green hydrogen as fuel for trains transporting goods to the port, Iberdrola stated.
It could also use the green hydrogen to produce clean ammonia and ethanol for export to international markets, it added.
The Spanish utility believes the electrolyser could be capable of producing 14,000 tonnes of green hydrogen per year in its first 100MW phase. It expects this output could be doubled in the future.
This output could include the fuelling of up to 1,300 green hydrogen trucks per year, Iberdrola added.
The electrolysis capacity would be located on a brownfield site, similar in size to a football pitch (about 7,140m2), the company explained.
It would be built close to the 2.9GW East Anglia Hub of offshore wind farms, which is due online from the middle of the decade. However, Iberdrola did not confirm which renewable energy projects would power the green hydrogen plant. A spokeswoman said that it would use "offshore, onshore [wind] and solar PV generation and through power purchase agreements to ensure 100% renewable electricity supply" for the green hydrogen plant.
Iberdrola did not confirm whether it would be the sole investor in the £150 million project. It also did not confirm whether a specific portion of the East Anglia Hub’s capacity would be reserved for green hydrogen production.
