Japan's 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.
the 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 by comprehensive consideration of the future of technology improvement, and comprehensive investigation into the battery and the capacity of the water electrolysis device, etc. , determine the international price competitiveness of low cost hydrogen production technology level. By developing completely before and after the May 2030, for example, practical, the discharge is slow but cheap batteries, Japan is expected to achieve per cubic meter of 17 & ndash; 27 the yen ( About 1. 04 - 1. 64 yuan) The cost of hydrogen production.
