Steam accumulator
A steam accumulator, also called a Ruths accumulator, is an insulated pressure vessel that stores hot water and releases it as steam when pressure drops.
Steam explosion
Steam explosion, also called autohydrolysis, is a pretreatment that heats lignocellulosic biomass with high-pressure steam and rapidly releases the pressure, rupturing cell walls for enzyme conversion.
Steam generator (nuclear power)
A steam generator in a nuclear power plant is a heat exchanger that transfers heat from radioactive primary coolant to a secondary loop, boiling water to drive the turbine.
Steam injection (petroleum)
Steam injection is an enhanced oil recovery method that heats heavy oil reservoirs with steam, cutting viscosity so oil can flow; main schemes include CSS, steam drive, and SAGD.
Steam reforming
Steam reforming, also known as steam methane reforming, is an industrial catalytic process in which methane reacts with high-temperature steam to produce hydrogen and carbon monoxide.
Steam trap
A steam trap is an automatic valve that drains condensate from steam lines and equipment while blocking live steam and venting air, using thermostatic, mechanical, or thermodynamic designs.
Steam turbine
A steam turbine, also called the Parsons turbine, converts thermal energy of pressurized steam into rotational mechanical energy; Charles Parsons built the first modern multi-stage design in 1884.
Steam-assisted gravity drainage
Steam-assisted gravity drainage (SAGD) is an enhanced oil recovery method that uses two horizontal wells to recover heavy oil and bitumen, widely used in Alberta's oil sands.
Steam-generating heavy water reactor
The steam-generating heavy water reactor (SGHWR) is a nuclear reactor design in which pressure tubes of enriched uranium fuel and boiling light water coolant pass through a heavy water moderator.
Stedin
Stedin is a Dutch distribution system operator that owns and runs the regional electricity and gas grids for about 5.6 million people in South Holland, Utrecht, and Zeeland.
STEGAL Gas Pipeline
STEGAL (Sachsen-Thüringen-Erdgas-Anbindungsleitung) is a 314 km natural gas pipeline in Germany, running from Olbernhau in Saxony to Reckrod in Hessen since 1992 and described as a route for importing Russian gas.
Stellarator
A stellarator is a magnetic-confinement fusion device whose twisting field comes entirely from external coils, invented by Lyman Spitzer at Princeton in 1951 and developed alongside the tokamak.
Stem Inc

Sterling & Wilson Renewable Energy is an Indian engineering, procurement, and construction contractor for utility-scale solar projects, headquartered in Mumbai and operating across 28 countries.
Sterno
Sterno, also known as Sterno Canned Heat, is an American brand of jellied alcohol cooking fuel in steel cans, used to keep food warm under chafing dishes.
Stirling solar dish engine
A Stirling solar dish engine is a concentrating solar power system in which a parabolic dish of mirrors focuses sunlight onto a Stirling engine that drives a generator.
Stock-tank oil initially in place
Stock-tank oil initially in place (STOIIP), also called original oil in place (OOIP), is the total crude oil in a reservoir before production, measured at surface conditions.
Stockbridge damper
A Stockbridge damper is a dumbbell-shaped tuned mass damper with two masses on a short steel cable, clamped to overhead conductors to dissipate wind-induced vibration, patented in the 1920s.
