Thank you for your hard work David! Do I understand correctly that the source of energy for the conversion is (mostly) the hydrogen?
I've been interested in if we could use large bodies of water (like lakes or ponds) to both get a lot of interaction with CO2 from the air, and get energy from the sun to capture carbon. Do you think fermentation could work outside, or would we need a more resilient organism like algae or even seaweed?
My idea is to float a dark membrane on top of the water, with a thin layer of water on top. The dark membrane heats the water, sustaining the algae, and then the algae get robotically harvested. Could that work for your organism?
- DavidPBL 5y agoI would describe hydrogen as an energy carrier rather than an energy source. Hydrogen is always made from something else, and the energy is either provided by that something else, or indirectly from another source, or a combination of both. If you use an electrolyser to make hydrogen from water, your energy source is actually the electricity used to drive that reaction. The energy is stored as hydrogen gas. Large bodies of water are great passive systems to capture CO2. For the outdoors, and if using sunlight is the energy source, algae and seaweed are definitely great candidates for capturing CO2. Unfortunately your idea wouldn't work for our microorganisms as it is anaerobic, so it would die if exposed to air. But I like your idea for using sunlight to improve the growing conditions of algae + using automation for harvesting!
