Siemens Energy and Beijing Green Hydrogen Technology Development Co. Ltd, a subsidiary of China Power International Development Ltd (China Power), have signed an agreement on providing a hydrogen production system for a hydrogen fuelling station. Located in Yanqing District, Beijing, the new production facility will help guarantee the hydrogen supply for the public transportation system. The MW scale solution is the first of its kind to be built by Siemens Energy in China. The project is expected to be delivered in May 2021.
In September 2019, Siemens signed a Memorandum of Understanding on co-operation in green hydrogen development and comprehensive utilisation with State Power Investment Corporation (SPIC), which is the ultimate controlling shareholder of China Power. The hydrogen production project is the result of a close partnership between the two companies. The two sides also plan to further expand their co-operation on green hydrogen projects.
Siemens Energy is expecting to help its customers achieve their decarbonisation goals by building infrastructure for Power-to-X and making a global contribution to cross-sector decarbonisation. Siemens Energy offers all core technologies for a long-term CO2-free energy supply – from power and heat generation by renewable energies or gas-fired power plants, to power transmission and distribution, to efficient electrolyser solutions for hydrogen production.
Electrolysis of hydrogen is called green if the electricity used comes exclusively from a renewable source, eg from wind farms, solar plants, hydro or geothermal power plants. The Siemens system uses a PEM (proton exchange membrane) electrolyser system, Silyzer 200, that it says can produce high-quality hydrogen at industrial scale. In addition, the hydrogen production system responds quickly, the start-up time under pressure is less than one minute, and it can be directly coupled with renewable energy.
