Spanish power and gas utility Naturgy Energy Group SA (BME:NTGY) is partnering with gas grid operator Enagas SA (BME:ENG) on a study to produce green hydrogen from 350 MW of floating offshore and onshore wind farms in Spain.
The companies plan to install the wind farms and set up electrolysers in Spain’s northwestern region of Asturias to produce enough green hydrogen to support the decarbonisation of the local steel industry and shipyards and export the rest to Europe, Naturgy said.
The floating wind component is planned to have a total of 250 MW of capacity by the end of the project. In the demonstration phase, Naturgy and Enagas will install a 50-MW floating wind farm, a 5-MW offshore electrolyser, a 100-MW onshore wind farm and a 100-MW onshore electrolyser.
In the second phase, the partners would boost the floating wind power capacity to 250 MW and add another 100-MW onshore electrolyser.
The floating technology will be developed by shipbuilder Navantia and wind tower maker Windar Renovables SL, which will manufacture up to 24 platforms through their joint venture.
The goal of the project is to gain experience from integrating electrolyser and renewable energy components at a large scale and work towards bringing down costs of the production of green hydrogen, added Naturgy.
The project is part of the Green Crane initiative launched by Enagas, which has already sought financing for its latest effort under the EU state aid tool for Important Projects of Common European interest (IPCEIs).
Enagas is engaged in a number of green hydrogen projects in its native Spain, forming partnerships with domestic energy players.
With Naturgy, Enagas has an ongoing project to produce hydrogen from 400 MW of solar power. The company is also part of a multinational consortium in the Green Hysland project, an island-wide initiative to help Mallorca switch to sustainable fuels and develop green hydrogen economy.
