7. Hydrogen production systems using solar energy include photolysis hydrogen production, solar power generation and water electrolysis hydrogen production. Solar hydrogen production has been developed in the past 30 to 40 years. Research on solar hydrogen production mainly focuses on the following technologies: thermochemical hydrogen production, photoelectrochemical decomposition, photocatalysis, artificial photosynthesis and biological hydrogen production.
8. Among hydrogen production methods, fossil fuel hydrogen production accounts for more than 90% of the world's hydrogen production. Hydrogen production from fossil fuels mainly uses a combination of steam reforming and pressure swing adsorption to produce high-purity hydrogen. Hydrogen production by electrolyzing water with electric energy also accounts for a certain proportion. Solar hydrogen production has been developed in the past 30 to 40 years. Research on solar hydrogen production mainly focuses on the following technologies: thermochemical hydrogen production, photoelectrochemical decomposition, photocatalysis, artificial photosynthesis and biological hydrogen production.
1. As early as 2018, LONGi began to pay attention to and deploy renewable energy electrolysis hydrogen production. In the past three years, LONGi has conducted in-depth R&D cooperation with well-known scientific research institutions and authoritative experts at home and abroad, and has accumulated technology in the fields of electrolysis hydrogen production equipment and photovoltaic hydrogen production. At the end of March 2021, LONGi Green Energy Venture Capital, a wholly-owned subsidiary, and Shanghai Zhuque Investment *** jointly established Xi'an LONGi Hydrogen Energy Technology Co., Ltd. to carry out hydrogen energy industrialization layout.
2. Inverter leader Solar Energy is one of the earliest listed photovoltaic companies in China to carry out research on photovoltaic hydrogen production. The company stated that it has established a dedicated hydrogen energy division and has carried out in-depth cooperation with the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, in advanced PEM electrolytic hydrogen production technology, integration of renewable energy and electrolytic hydrogen production, and hydrogen energy optimization. Production systems, etc.
3. Since 2019, Baofeng Energy, a leading company in high-end coal-based new materials, has launched a hydrogen production project. In April 2020, the company's "Solar Electrolysis of Water Hydrogen Production, Energy Storage and Comprehensive Application Demonstration Project" started construction at the Ningdong base in Ningxia. The project will involve solar electrolysis of water for hydrogen production, hydrogen storage and transportation, hydrogenation stations, demonstration applications of hydrogen energy transportation, and coupling with modern coal chemical industry to produce high-end new chemical materials.
4. In 2019, Jinko Technology stated: “By 2025, the huge progress in ‘photovoltaic + energy storage’ hydrogen production system technology will make large-scale application economically feasible.” To this end, the company's domestic and overseas layout: Abroad, the company signed a 2020 strategic cooperation agreement with Air Products. The two parties will cooperate in the field of photovoltaic new energy and combine "hydrogen production" with "green electricity." "; In China, the company is focusing on promoting the implementation of renewable energy hydrogen production projects.
I hope it can help you.
