I'm pretty excited about Solar Foods; since it's "just" an industrial-grade biological process, you could set it up in any suitable industrial facility.

My hope is that this would let us disconnect nutrition from crop-failure-due-to-weather (well, normal weather like drought or unseasonal rains) and (maybe) become post-scarcity with respect to nutrition. Just as solar, wind and batteries allow us to create reliable electricity sustainably and reduces energy prices, I hope this technology allows us to reduce the risk of famine and reduce the base cost of a (healthy) calorie.

Plus in theory this could be used to support space colonies, which I think would be a nice addition to humanity's skillset.

Another competitor in this space is the California-based company Air Protein.
