Construction has begun on a 30MW 100%-hydrogen turbine in Ordos, northern China. The turbine is being implemented into a renewable energy storage and generation system in the Otoke High-Tech Industrial Development Zone.<\/p>\n
According to a report<\/a> from Fuel Cell Works, this will link wind, solar, hydrogen storage, electrolysis, and green ammonia in a single closed-loop energy system. The project aims to prove the viability of large-scale hydrogen-fired generation.<\/p>\n The turbine will run solely on hydrogen, instead of an H2-natural gas blend, marking a world-first achievement for a project of this scale.<\/p>\n China\u2019s new 100% hydrogen turbine<\/p>\n In 2020, Japan\u2019s Kawasaki Heavy Industries demonstrated a 100% hydrogen turbine. Siemeins unveiled its 100%-hydrogen model in 2023. However, China\u2019s new project is the first to integrate its turbine with large-scale renewables and on-site storage directly. This means it will be the first of this scale to run exclusively on hydrogen.<\/p>\n The development is part of the Ejingke wind-solar-hydrogen integrated green ammonia project. Mingyang Hydrogen, a subsidiary of Mingyang Smart Energy, and Shenzhen Energy are jointly developing it.<\/p>\n The turbine will have a 500MW upstream wind capacity. It will feature a 5MW off-grid photovoltaic array and 240MW of electrolysers producing 48,000 Nm\u00b3 of hydrogen per hour (about 4.3 tonnes\/hour). It will include twelve 1,875 m\u00b3 spherical storage tanks and a plant that produces 150,000 tonnes of green ammonia annually.<\/p>\n An \u2018electricity\u2013hydrogen\u2013electricity\u2019 closed-loop cycle<\/p>\n Ultimately, the goal of the project is to deploy an \u201celectricity\u2013hydrogen\u2013electricity\u201d closed-loop cycle. This will convert green power to hydrogen, store it, and then use it for electricity generation during periods of low renewable output. This will help to stabilise supply and address grid intermittency.<\/p>\n The facility will be key in Inner Mongolia\u2019s ambitions to become a national hydrogen energy demonstration hub. It could serve as a guide for future projects worldwide looking to integrate hydrogen into renewable-heavy grids.<\/p>\n According to the Fuel Cell Works report, critics have highlighted the energy losses associated with electrolysis, storage, and combustion. This, they say, could lead to high energy costs.<\/p>\n However, by building a comprehensive green hydrogen ecosystem, China aims to become a world leader in clean energy. The country has made great strides this year. Between January and May, it added 198 GW of solar and 46 GW of wind. According to a report<\/a> from The Guardian, that is equal to the full electricity output of Indonesia or Turkey.<\/p>\n
