Molten carbonate fuel cell
A molten carbonate fuel cell (MCFC) is a high-temperature fuel cell that uses molten carbonate salts as its electrolyte and operates at about 650 degrees C for stationary power generation.
Molten chloride salt thermal energy storage
Molten chloride salt thermal energy storage is a high-temperature storage technology using liquid chloride salts such as NaCl-KCl-MgCl2, stable above 400–800 °C for power generation.
Molten chloride salts for concentrated solar power
Molten chloride salts for concentrated solar power are a cheap MgCl2/KCl/NaCl mixture for next-generation CSP plants near 720 °C, paired with supercritical CO2 Brayton cycles.
Molten Salt Fast Reactor
The Molten Salt Fast Reactor (MSFR) is a Generation IV nuclear reactor concept in which molten fluoride salt serves as both liquid fuel and coolant in a fast neutron spectrum.
Molten salt reactor
A molten salt reactor (MSR) is a nuclear fission reactor in which molten salt serves as fuel, coolant, or both instead of solid fuel rods and pressurized water.
Molten salt thermal energy storage
Molten salt thermal energy storage stores sensible heat in molten nitrate salts in insulated tanks; it dominates concentrating solar power storage and offers 93–98% thermal round-trip efficiency.
Molten salt thermal storage
Molten salt thermal storage is a high-temperature energy storage method that stores heat in liquid salt tanks, used mainly in concentrating solar power plants to generate steam for turbines.
Molten-metal methane pyrolysis
Molten-metal methane pyrolysis is a hydrogen production process in which methane bubbles through molten metal or salt near 1000 °C, splitting into hydrogen and solid carbon without producing carbon dioxide.
Molten-salt battery
A molten-salt battery is a battery using molten salt as an electrolyte, ranging from primary thermal cells to rechargeable types such as the sodium-sulfur and sodium-metal halide (ZEBRA) batteries.
Molten-Salt Breeder Reactor
The Molten-Salt Breeder Reactor (MSBR) was a thermal-spectrum reactor concept from Oak Ridge National Laboratory that used a thorium fuel cycle in circulating molten fluoride salt.
Molten-Salt Reactor Experiment
The Molten-Salt Reactor Experiment (MSRE) was an experimental nuclear reactor at Oak Ridge National Laboratory, Tennessee, that ran from 1965 to 1969, with uranium fuel dissolved in circulating molten fluoride salt.
Molten-silicon thermal energy storage
Molten-silicon thermal energy storage is a grid-scale storage concept that stores electricity as heat in silicon at 1414 °C, discharging it as heat or electricity.

Monitored Retrievable Storage
Monitored Retrievable Storage (MRS) is a US Department of Energy concept for above-ground interim storage of spent nuclear fuel before permanent disposal, proposed in Tennessee but never built.
Monju Nuclear Power Plant
Monju (もんじゅ) was a 280 MW prototype fast breeder reactor in Tsuruga, Fukui, Japan, Japan's only breeder reactor with power generating capability, abandoned after a 1995 sodium leak.
Mono-like silicon
Mono-like silicon, also called cast-mono or quasi-mono silicon, is photovoltaic silicon grown by directional solidification on monocrystalline seeds, combining mono-like efficiency with cheap multicrystalline casting.
Monocrystalline silicon
Monocrystalline silicon, also known as mono-Si or c-Si, is silicon in the form of a single continuous crystal lattice, used as the absorbing semiconductor in most solar cells and grown mainly by the Czochralski process.
