Can factories install local battery banks to cover a day’s utilization? Charge up the batteries on the cheap electricity during noon and run the plant off of those reserves. I assume other industries are already running these cost optimization analyses as the renewable electricity market continues to develop. There is a balancing point between the capex and opex, but unless it is insanely energy hungry (like aluminum), that seems possible.
- jandrewrogers 2y ago> but unless it is insanely energy hungry (like aluminum) Producing a ton of hydrogen by electrolysis requires ~3x the energy to produce a ton of aluminum. It is, in fact, "insanely energy hungry". This isn't necessarily a problem but it does create logistical challenges.
- marcosdumay 2y agoWhat comes back to the fact that you only need batteries for the ammonia production. Hydrogen production is a low-pressure process, and optionally even low-temperature.
- quickthrowman 2y agoIt takes 11 MW of electricity to make 1 ton of ammonia, ammonia plants can make 1000 to 3000 tons a day. Providing battery storage for that production rate for 24 hours would probably cost more than the plant itself.
- pfdietz 2y ago> It takes 11 MW of electricity to make 1 ton of ammonia Do you mean MWh? Because the units given don't make sense. But 11 MWh would be too low.
