DICP's 250-kW system co-produces hydrogen and fresh water from seawater
A Dalian Institute of Chemical Physics team reports in Nature Energy, published September 15, 2026, a 250-kW system that couples alkaline water electrolysis with low-temperature seawater distillation driven by the electrolyser's waste heat: 48 Nm³/h of hydrogen and 31.6 kg/h of fresh water, with a 14.4% improvement in system electrical efficiency relative to alkaline electrolysis of fresh water alone, per the abstract. The institute's September 16 release says the 250-kW unit was completed in August 2024 and has run stably for more than 40 days.
Skyven reports sustained COP of 8.0 at its Arcturus steam heat pump demo
Skyven Technologies announced on September 2, 2026 that its 1 MWth Arcturus steam-generating heat pump demonstration center in Dallas, Texas has achieved a sustained coefficient of performance of 8.0, up more than 20% from the 6.5 the company reported at commissioning on November 20, 2025. Skyven says Arcturus delivers lifts from 38°C to 185°C with COPs from 8.0 down to 2.0, and the release names no customer installation.
KIMM demonstrates ammonia heat pump cooling from 40°C waste heat
The Korea Institute of Machinery and Materials announced on August 5, 2026 that it demonstrated a chemical adsorption heat pump providing cooling from waste heat of approximately 40°C, well below the 70°C-plus that conventional adsorption systems require. Samjung Tech built a 10 kW-class prototype, and KIMM says the redesigned adsorption bed reaches a specific cooling power of 346.5 W/kg, more than twice that of comparable international technologies.
