[DIYbio] Growing Cupriavidus necator

The first time I read about the bacteria Cupriavidus necator it still had the name Ralstonia eutropha (my source that those are the same bacteria is wikipedia), so on this site I searched on both but didn't find what I was looking for. To just cut and paste something I wrote in another context (very basic, you can skip it if you know anything about it already). One (there are several) interesting features of C. necator is that it can take energy from, and live on, hydrogen. This means that you can use solar energy to divide water into hydrogen and oxygen and feed the bacteria with it. The point is that solar cells are much more efficient than photosynthesis. Plants use only ~ 1% of all solar energy that hits their leaves. Using solar cells and bacteria that eat hydrogen is both in theory and in practice a more efficient method of producing a biomass than photosynthesis is.

So yeah, that's my understanding of those types of bacterias. And my question is if anyone has, or if it's theoretically possible, to build a low tech incubator for C. necator? Like water, with some nutrients, as a growth medium in a water tank or pipes with an airstone for aquariums to deliver hydrogen gas?

In the simplest form this should just be a method to produce biomass - I guess one  could make compost from it and use it for soil improvement and carbon sink. Then the follow up question is, how do one harvest bacteria? And of course I can fantasize about taking one step more, use the bacteria to produce nutrition for other organisms. Like there's they who do research on lab grown wood. In vitro wood grown with sugar from hydrogen feed C. necator¸ should be more efficient than ordinary trees and save the forests.
