Toyota plans to use regenerative fuel cell technology to power a manned lunar rover, executives said on Friday, raising the prospect of eventually using the moon’s water ice as an energy source in the future.

Japan has stepped up its space ambitions under Prime Minister Fumio Kishida.

It is participating in NASA’s Artemis program and plans to have an astronaut at a lunar space station called Gateway as part of that in the latter half of the 2020’s.

Toyota has teamed up with the Japan Aerospace Exploration Agency since 2019 to develop the manned lunar rover — which it dubbed the Lunar Cruiser — that they hope can be put on the moon in 2029.

“In order to conduct long-term and stable research on the surface of the moon, we are aiming to source various items on site over a long period,” said Ken Yamashita, head of lunar exploration projects at Toyota.
