Honda to test compact hydrogen system for space exploration on the ISS

In context: As humanity moves toward building permanent habitats off-Earth, researchers are developing reliable energy systems to support life in extreme environments. They've long studied electrolysis to generate oxygen and hydrogen in space, but low gravity reduces its efficiency. Honda plans to tackle this problem by testing its system aboard the International Space Station. Honda is aiming beyond Earth with plans to test its high-differential pressure water electrolysis system aboard the International Space Station. In partnership with Sierra Space and Tec-Masters, the company hopes the technology will support a regenerative fuel cell system for sustaining life on the Moon – and potentially offering scalable energy solutions on Earth. The centerpiece of Honda's effort is a circulative renewable energy system designed to continuously generate oxygen, hydrogen, and electricity. Drawing on decades of fuel cell expertise, the company plans to build infrastructure that uses lunar reso ... Read full article.
