Liquefied natural gas
Liquefied natural gas (LNG) is natural gas, mostly methane, cooled to about -260 degrees Fahrenheit into a liquid 600 times smaller in volume, enabling shipment across oceans by tanker.
Liquefied natural gas as bunker fuel
Liquefied natural gas as bunker fuel is the use of natural gas, chilled to a liquid, as fuel for ship engines instead of oil-based marine fuels.
Liquefied petroleum gas
Liquefied petroleum gas, or LP gas, is a fuel of mainly propane and butane, stored as a liquid under pressure and used for cooking, heating, and transport.
Liquid air energy storage
Liquid air energy storage, also called cryogenic energy storage, is a grid-scale technology that stores surplus electricity as liquid air and regasifies it to generate power.
Liquid fluoride thorium reactor
The liquid fluoride thorium reactor (LFTR) is a proposed molten salt reactor that breeds fertile thorium-232 into fissile uranium-233 in liquid fluoride fuel salt, descending from Oak Ridge's 1950s molten salt work.
Liquid hydrogen
Liquid hydrogen (LH2) is hydrogen cooled below its −252.8 °C boiling point, about 850 times denser than the gas and used as a common rocket propellant.
Liquid hydrogen tank
A liquid hydrogen tank is a double-walled, vacuum-insulated cryogenic pressure vessel storing hydrogen at about −253 °C, used for bulk storage, transport, and rocket propellant.
Liquid metal thermal energy storage
Liquid metal thermal energy storage is a high-temperature storage method in which molten metals such as sodium, lead, or tin move heat into and out of a solid storage medium.
Liquid organic hydrogen carriers
Liquid organic hydrogen carriers (LOHCs) are organic liquids that store hydrogen by reversible catalytic bonding, allowing transport at ambient temperature and pressure using existing fuel infrastructure.
Liquid Piston Compression
Liquid piston compression is a method of compressing gas in which a pumped liquid column, usually water, displaces the gas, removing heat efficiently for near-isothermal compressed air energy storage.
Liquid piston compressor
A liquid piston compressor is a positive-displacement gas compressor in which a rising liquid column displaces and compresses the gas, replacing the solid piston and crankshaft.
Liquid sunlight
Liquid sunlight (液态阳光), or liquid solar fuel, is a technology named in 2018 that stores renewable electricity as liquid methanol from green hydrogen and captured CO2.
