High River power station (潞安长子高河低热值煤电厂) is a 1,320 MW coal-fired power station in Changzhi, Shanxi, China, with two 660 MW ultra-supercritical units burning low-calorific-value waste coal since 2021.
High Sulphur Fuel Oil
High Sulphur Fuel Oil (HSFO) is a residual marine fuel with up to 3.5% sulfur, the dominant bunker fuel for ships until the IMO 2020 sulfur cap.
High-assay low-enriched uranium
High-assay low-enriched uranium (HALEU) is uranium enriched to between 5 and 20 percent uranium-235, above today's reactor fuel; most U.S. advanced reactors are built around it.
High-burnup fuel
High-burnup fuel is nuclear reactor fuel discharged at a burnup of 45 GWd/MTU or more, a level the US Nuclear Regulatory Commission treats as high, pursued mainly for economic reasons.
High-concentration electrolytes
High-concentration electrolytes (HCEs) are battery electrolytes with salt levels typically 3 to 5 M, where anions enter the cation's solvation shell and change interphase chemistry.
High-entropy cathode
A high-entropy cathode is a battery positive-electrode material in which five or more elements share active cation sites in near-equiatomic proportions, stabilized by high configurational entropy.
High-entropy electrolyte
A high-entropy electrolyte (HEE) is a battery electrolyte, liquid, gel, or solid, that mixes multiple salts, solvents, or ions to raise disorder, improving ionic conductivity, interfacial stability, and cycling.
High-entropy layered oxide cathodes
High-entropy layered oxide cathodes (HELOs) are battery cathode materials in which five or more cation species share a layered oxide sublattice, stabilizing the structure during cycling.
High-entropy oxide electrocatalysts for oxygen evolution
High-entropy oxide electrocatalysts for oxygen evolution are single-phase oxides containing five or more metals that catalyze the oxygen evolution reaction, an alternative to costly iridium and ruthenium catalysts.
High-entropy solid electrolytes
High-entropy solid electrolytes (HESEs) are solid ion-conducting battery materials that mix several cations or anions into one disordered lattice, an approach adapted from high-entropy alloys to raise ionic conductivity.
High-frequency transformer
A high-frequency transformer transfers power at frequencies far above the 50 or 60 Hz grid, typically tens of kilohertz, providing galvanic isolation in switched-mode power supplies, DC-DC converters, and solid-state transformers.
High-pressure grinding rolls
High-pressure grinding rolls (HPGR) are comminution machines that crush rocks and ores between two counter-rotating rollers, cutting grinding energy use by 20–40% in mining and cement.
High-pressure water scrubbing
High-pressure water scrubbing is a biogas upgrading technology that removes carbon dioxide by dissolving it in pressurized water, historically the most widely used upgrading method worldwide.
High-strength pipeline steel
High-strength pipeline steel is line pipe steel of grade X80 and above in the API 5L system, used for large-diameter, high-pressure oil and gas pipelines.
High-temperature co-electrolysis of steam and CO2
High-temperature co-electrolysis of steam and CO2 is a process in which a solid oxide electrolyzer cell at 650–900 °C turns renewable electricity, water, and CO2 into synthesis gas.
High-temperature gas-cooled reactor
A high-temperature gas-cooled reactor (HTGR) is a graphite-moderated, helium-cooled nuclear reactor with ceramic-coated TRISO fuel, reaching coolant temperatures of 700–950 °C; China's HTR-PM became the first commercial-scale plant in 2023.
High-temperature phase-change materials
High-temperature phase-change materials are substances that store thermal energy as latent heat while melting and solidifying above about 300 °C, for use in concentrated solar power and industrial waste-heat recovery.
High-temperature steam electrolysis
High-temperature steam electrolysis (HTSE) splits steam into hydrogen and oxygen using solid oxide electrolysis cells at 500–1000 °C, needing roughly 35% less electricity than conventional low-temperature electrolysis.
High-voltage direct current
High-voltage direct current (HVDC), also called high-voltage DC, transmits electrical power as direct current at high voltage, used for long-distance bulk transmission, submarine cables, and connecting unsynchronized AC grids.
