Japan Japanese Life Support Systems for Space Travel/Habitat

For SpaceNut .... there are several topics that include "Japan" but none seem to cover this work ... … 00655.html

Honda announced its plans to partner with the Japan Aerospace Exploration Agency (JAXA) for a joint feasibility study on a circulative renewable energy system.

While most car companies focus their efforts on creating a clean and renewable energy source for cars, SUVs, and trucks, Honda and JAXA look to pioneer a renewable energy system that can supply oxygen, hydrogen, and electricity for human outposts and rovers in space.

Both parties have signed a three-fiscal-year joint research agreement to pursue studies in achieving this goal. The results of Honda and JAXA’s combined research will be used on Lunar Orbital Platform-Gateway (Gateway) and on the surface of the moon.

“Based on the Japanese government's decision to participate in the Artemis program, JAXA has been working on mission development and system studies for realizing full-fledged lunar exploration. Oxygen, hydrogen, and electricity are essential to human activities in space. Realizing a circulative renewable energy system will enable us to obtain these requirements in space without relying on a resupply from Earth. This is expected to dramatically expand our activities in space. We would like to make steady progress in this study by leveraging the respective strengths of Honda and JAXA.,” said JAXA Vice President and Director General for Human Spaceflight Technology Directorate Sasaki Hiroshi.

In this joint project, Honda will be using its high differential pressure water electrolysis and fuel cell technologies. Through solar energy, it can electrolyze water which will then produce oxygen and hydrogen.

If there is anyone in the active membership who can explain how a "high differential" system differs from a "normal" system, I'd appreciate there contributing to this topic.

If there is someone in the forum readership NOT already a member, who might be able to assist with an explanation, please check the Recruiting topic for procedures.
