Open Source Thermal Energy Storage Construction Set
From Open Source Ecology
Consists Of
Solid Storage Medium (SSM)
Concrete Blocks
Metal Blocks
Geothermal Heat Storage
Liquid Storage Medium (LSM)
Water
Oil
Molten Salt
- Sodium Chloride Melts at 801 °C and Boils at 1,413 °C
- Quite Common
- Is good on most points, but kind of corrosive + it has a high operating temperature
Molten Metals
- Lead-bismuth eutectic alloy (LBE; 45% Pb, 55% Bi) melts at 125 °C and does not boil until 1670 °C (Ideal, but toxic, corrosive + hard to obtain)
- Aluminium Melts at 659 °C and boils at 2470 °C (Non-Toxic, Easy to Find, But High Minimum Operating Temperature
- Note that steel pipes melt ~1371 °C So that is probably around the upper limit of operating temperature
Gas Storage Medium (GSM)
Steam
Compressed Air
Phase Change Material Medium (PCMM)
Sodium Hydroxde
- Works by evaporating the water from a soduium hydroxide solution to store energy, and adding water back in to release energy
- Less energy dense, but potentially infinite storage time (at room temperature)
Hybrid Storage Medium (HSM)
Saturated Water
- IE "Steam Accumuators"
- Hold Water at A High Temperature and Pressure. More Pressure is Created from Superheated Water Going to Steam when pPressure is Removed for Turbines/Motors etc
- Open Source Steam Accumulator
- Saturated Water
Liquid and Solid Mixture
- Such as Oil and Gravel, or Oil and Glass Beads
Uses
Allows For
- Energy Storage (For grid/house level electricity storage)
- Indirect Thermal Vehicles (Combustionless Locomotives etc)
