Photovoltaic solar power company of Japan is expected to achieve low cost hydrogen production

Editor's note: Japan material research institute ( 年来的) In collaboration with the university of Tokyo and Hiroshima university, if can be acidic sulfide semiconductor material as catalyst for water decomposition reaction of light, is expected to achieve low cost hydrogen production process.

in 2019, the Japanese material research institute ( 年来的) In collaboration with the university of Tokyo and Hiroshima university, for hydrogen production system of photovoltaic power generation and storage battery technology economic benefit evaluation, confirmed the international price competitiveness of low cost hydrogen production technology level, in the technology development of renewable energy to become the main power supply, the results can be used as an important guide. Team designed according to the photovoltaic power generation, adjust the battery charge and discharge amount and integrated system, the amount of water electrolysis hydrogen production to evaluate its technical and economic benefits, China solar power network, through the comprehensive consideration of the future of technology improvement, and comprehensive investigation into the battery and the capacity of the water electrolysis device, etc. , to determine the low cost hydrogen production technology. Through the development of around 2030 is possible to develop practical, discharge is slow but cheap battery, Japan is expected to achieve per cubic meter of 17 ~ 27 yen ( About 1. 04 - 1. 64 yuan) The cost of hydrogen production.

kyushu city university research team developed a greenhouse environment with low energy visible light, just one more step can be realized from methane ( CH4） Conversion of ethane ( C2H6） And hydrogen ( H2） A new type of photoelectric chemical reaction process. By applying an electric field, light stimulates the recombination of electrons and holes are suppressed, compared with the traditional method of photocatalytic reaction, the quantum efficiency is greatly improved, for the first time using visible light energy to make hydrogen gas at room temperature.

in central Japan university developed a type used for solid oxide fuel cell ( SOFC） A new type of air electrode materials, SOFC as household fuel cell system & other; 烯- 农场” Is gradually popularization, the working temperature is about 750 ℃. Also improved as the work temperature is reduced, start, so can also use the mobile body, solar equipment, can consider applied to the auxiliary power supply of the plane ( APU） And EV extended range of engines.

Japan's new energy industry technology comprehensive development agency ( NEDO） In collaboration with the university of Tokyo and shinshu university, gateway to solar energy, solar energy, first developed using visible light to split water into hydrogen and oxygen acid sulfide photocatalyst. The development of catalysts for the production of micro particle future large sheet, photocatalyst spraying method such as simple process convenient application. If can be acidic sulfide semiconductor material as catalyst for water decomposition reaction of light, solar energy, is expected to achieve low cost hydrogen production process.
