Very cool, except first you need to get the hydrogen. For that I believe he is planning to use the "artificial leaf" he has invented previously. Problem is, while the bacteria can reproduce on their own, the leafs won't. They are made from silicon so probably similar tech to regular solar cells. This can be likely a limiting factor here. Still interesting news.
