- Electrolyzers can produce hydrogen at pressure, so a compressor is not needed.
Calculations
- Cost targets - https://energy.gov/eere/fuelcells/hydrogen-storage
- 1kWhr=3.6MJ. 1 kG of hydrogen is 142MJ/kg
- Cost for car tanks target - $15/kWhr - or about 40x for 1 kG - $600/kg. (above reference)
- Cost or stationary storage goal - $1000/kg - [1]
Storage Tank Suppliers
- 700 bar, 20 gallon - [2]. RFQ submitted 1/27/18
- In-ground storage, 2200 PSI - 14"x40' - [3]
- Low, medium, and high pressure storage options - [4]
- Pictures of storage tanks - [5]
Cryogenic Storage
- Ultra High Density
- Can be done using a Delwar, a pure hydrogen gas source, and a cheap cryocooler
- A diy cryocooler could possibly be made to reduce costs further
Storage as a Synthesized Fuel
- Convert to Methane by the Sabatier Reaction
- That can be compressed/liquified as is or it could be further converted into other fuels
- Methanol can be made from methane via the following process Listed Here
- Dimethyl Ether can be made from Methanol This Details How
- Dimethyl Ether Can be Catalytically Converted to Hydrocarbons such as Gasoline This Details How
- Hydrogen + Carbon Monoxide can be directly converted to hydrocarbons via the Fischer Tropsch Process
Links
- This reports the cost of tanks at low-thousands scale for a car - [6]
- Energy.gov state of art technology report - [7]
- In an open source economy, these costs make hydrogen storage feasible at today's prices - deployable via community-supported manufacturing.
