Basics

Conversion of Electricity (ie power) to Non-Fuel Chemicals
This is typically chemicals using Syngas or Hydrogen as a feedstock
Bioreactor using microbes and/or algae to make food and other valuable chemicals

- Although framed moreso as a power storage media, they do mention agricultural/industrial/scientific use as well
A Video by the Youtube Channel "Just Have a Think" Titled "Decarbonising AMMONIA production. Could a revolutionary new process be the key?" (Discusses a novel method of Direct Electrolytic Ammonia Production (Given it's like an Electrolyser it should work better with Itermittent Power unlike the Haber-Bosch Process which runs best continously supposedly (to prevent Catalyst Poisoning i guess, but that may just be an economic need to keep the machine going not a technical like the poisoning explanation would suggest? Need to look into this). Either way since this is at STP / near it, it should be more energy efficient)
