The turbine at the Emsland gas power plant runs on hydrogen, natural gas or any mix of the two. Tests with up to 100% hydrogen are planned over the coming months.
Argo Space, a company with fewer than 30 employees, is building a spacecraft that splits water into hydrogen and oxygen for combustion. Its July demonstration did not test the propulsion.
Europe's Prometheus prototype demonstrated multiple restarts without a starter system and verified a cold-gas-sprayed combustion chamber.
The production car uses a single tank for methanol and gasoline, offering up to 1,880 km of range.
The 2026–2028 contract with Yakovlev covers development, certification and flight tests. The reason is the growing difficulty of keeping SaM146 engines airworthy.
The new hybrid system is built around 1.5-litre four-cylinder engines, smaller electric motors and compact power electronics, and is designed for several drive types.
The TF-35000 engine aims to enhance the KAAN stealth fighter's performance and domestic production capabilities.
Researchers demonstrated a laboratory prototype combustion actuator that regenerates its fuel from water by electrolysis, removing the need for external refueling.
Two heat pumps in Esbjerg, Denmark, used 19.9 MW of electricity and supplied 55.2 MW of heat at 90°C from 3.3°C seawater in a two-hour winter test. The plant is rated at 70 MW.
The US patent describes making the piston from a crown, a skirt and an outer ring joined by welds. The document contains no test data.
The integrated test flight aims to recover both rocket stages at the launch pad to advance full system reusability.
The Florida developer presented a hybrid powertrain project designed to carry 2,000 pounds over 1,000 nautical miles.
Integrated surface and reservoir modeling indicates hydrogen turbines offer lower capital expenditure and storage costs than fuel cells.
A functioning reproduction of the internal combustion engine designed by Eugenio Barsanti and Felice Matteucci will be showcased in Italy.
