About
Hydrogen can be an abundant energy source. With personal hydrogen appliances and solar energy, energy abundance is possible in a distributed way.
To do so, we need:
- Open source HICE as the next engine of civilization. Modular and scalable, manufactured in local microfactories with digital age precision.
- Storage vessels
- Hydrogen generation at low cost from renewable energy, demonetizing energy. As opposed to Brown Hydrogen
Cost of Production and Storage
- Cost of green hydrogen is $4.5/kg in 2023. [1]
- p13. 1 GW [2] of electrolysis has been installed by 2024, and 12 GW have passed Financial Investment Decision (FID) [3]. 1 GW of electrolysis is about a million metric tons per year or a billion kg. The equivalence is about 1 watt of electrolyzer to 1 kg per annum - good figure to remember
Bogus. 1 watt is under 9kWhr per year if running 24/7 - how do we get 1 kg if electrolysis cost 55kWhr/kg?
- Projections of 300 GW by 2030 are announced on p. 11 [4] but reality so far was 20% meeting of goals to present.
- p17 - Hydrogen refueling stations increased from 700 to 1100 between 2021 and 2023 worldwide.
- p13. 1 GW [2] of electrolysis has been installed by 2024, and 12 GW have passed Financial Investment Decision (FID) [3]. 1 GW of electrolysis is about a million metric tons per year or a billion kg. The equivalence is about 1 watt of electrolyzer to 1 kg per annum - good figure to remember
- This is for centralized production. OSE proposes ntegrated decentralized production on the home and village scale, which can be done today at approximately $1.4/kg if you DIY.
- Cost of solar electricity: 1 kW installed yields 66MWhrs over life of the PV panel (see Minimum Cost Solar for the 20 cent case), with BOS costs near zero in a building integrated system with efficient wiring and stringing to feed an electrolyzer directly with minimum power management equipment.
- The above 66 MWhrs
