A hydrogen turbine operated without a compressor for 303 seconds, setting a new record

Researchers have made a significant discovery in the field of hydrogen turbines, operating a gas turbine without a compressor for 303 seconds, surpassing NASA's previous record of 250 seconds. This turbine utilizes an advanced form of combustion with pressure rise, allowing for longer operation without the risk of melting the combustion chambers.

The new system generates the necessary pressure directly in the combustion chamber, eliminating the need for a mechanical compressor, which consumes a significant portion of the turbine's power. This innovation not only reduces energy losses but also the number of moving components, increasing overall efficiency. Hydrogen, produced from renewable sources, is ideal for this technology due to its rapid reaction.

Researchers anticipate that this approach will lead to lighter, cheaper turbines with high efficiency, having applications in electricity generation and aviation in the long term.
