Skyven reported sustained COP 8.0 at its 1 MWth Texas steam-heat-pump demonstration center on 2 September 2026, up from 6.5 at commissioning. This is a supplier disclosure; the announcement does not give the demo temperature pair or measurement boundary.

Architecture

Result status

The September 2026 announcement replaces the earlier roadmap with a supplier-reported result of 8.0. The numeric COP field remains blank because comparable test conditions are missing.

Architecture

Oil-lubricated screw/screw cascade: ammonia lifts refrigeration heat to about 82°C, pentane then produces steam

SPH / JOA demo card (installation year 2025): at Philip Morris Manufacturing & Technology Bologna, a two-stage heat pump turns dryer exhaust heat into saturated steam at 139°C and 2.5 bar(g). Rated duty is 650 kW. A FAT COP of 2.5 is source-reported, not remeasured here.

Temperature lift

Architecture

Two-stage reciprocating heat pump (SPH) integrated by JOA with direct recovery from humid dryer exhaust

Result status

The card lists installation year 2025, about 5,000 h/a, and a COP of 2.5 measured during factory acceptance testing. That FAT figure is not a published multi-season site audit.

Lüchu Technology (9 Apr 2026): a 2 MW-class very-high-temperature heat-pump storage demo at Xisai Science Valley, Huzhou, Zhejiang, China, reached full load. It uses air as the heat-pump fluid and molten salt as storage, and is reported to release superheated steam near 540°C at a COP of 1.41 from about 45°C waste heat. Not a process-steam heat pump, and not independently metered here.

Temperature lift

≈ 495 K

Architecture

Reverse Brayton-style air heat pump charging molten salt, then releasing high-temperature steam — heat-pump storage, not closed-cycle steam generation plus MVR

Result status

The builders reported full-load operation on 9 Apr 2026. Electric input is about 1.5 MW and heating output about 2 MW. COP 1.41 is source-reported for the 45°C source. A separate 8 MW / 400°C phase was announced earlier and is not treated here as this operating unit.

Shanghai Electric (acceptance 9 May 2025): a 1.1 MW / 10.8 MWh molten-salt store coupled to a high-temperature heat pump, supplying industrial steam at a factory in Fengxian, Shanghai. This is thermal storage plus a heat pump, not a process-steam heat pump of the closed-cycle plus MVR type. Not independently metered here.

Architecture

Single-tank molten-salt storage coupled to a high-temperature heat pump for green steam

Public project note: BASF has started construction at Ludwigshafen, Germany, of an open heat-pump system (GKT CompriVAP, formerly GIG Karasek) meant to turn steam-cracker waste heat into up to 50 MW of process steam. Commissioning is scheduled for mid-2027. This entry is under construction, not an operating case.

Architecture

Vicinity’s May 2026 update keeps its 35 MW Charles River heat-pump complex at Kendall on a 2028 installation target. The stated role is to preheat water for an electric boiler supplying district steam. It remains an engineering/construction project, not an operating heat-pump case.

Result status

The 11 May 2026 owner update says heat-pump engineering is active and installation is planned by 2028. Kendall’s electric boiler entered service in November 2024; its eSteam supply is not evidence that the heat pump is operating.
