In addition to water and food, people need oxygen, as well as hydrogen for fuel and electricity for various activities for life in space. One of the solutions to obtain them in space without resupply from Earth is creating a circulative renewable energy system, which combines a high differential pressure water electrolysis system that produces oxygen and hydrogen using solar energy to electrolyze water and a fuel cell system that generates electricity and water from oxygen and hydrogen.
Based on this concept, in
In this joint research, while JAXA has been developing the study conditions according to the scenarios and requirements for missions related to the production of oxygen on the
During the current fiscal year (JFY 2021), JAXA and Honda, utilizing the prototypes, will start the feasibility study addressing the issues on component technologies of the circulative renewable energy system identified by the research conducted during the last fiscal year. JAXA and Honda are planning to reflect the results of this year's study on the viability evaluation of the whole system in the next fiscal year (JFY 2022).
