Scientists have successfully generated electricity with a hydrogen turbine that produces its own pressure through detonation waves instead of relying on a mechanical compressor. The breakthrough could unlock dramatically more efficient power systems for clean energy and future aviation.
This hydrogen turbine turns controlled explosions into electricity

There probably is some novel idea here, but the headline and description could also apply to regular gas engines...

It's referring to a detonation wave engine that does not require a compression stage.

The article isn't very clear about how compression in this engine is achieved, but it's clear that compression is still required.
How is this different?

In a detonation wave, the exhaust gases reaches a very high pressure almost immediately, and you use this effect to drive a turbine. This eliminates the need for a compression stage.

Thank you, but that explanation is causing more confusion because it is at odds with the article. The article states that compression is required before ignition. Is that true?
If not, then in the detonation engine, is the fuel mixture already at explosive concentrations upon mixing?

You need to read the article more carefully. It is expilicitly pointing out that only conventional gas turbines need compression. A detonation wave engine does not.

I'm specifically referring to that line.

Please read that sentence more carefully. It is not saying what you think it is saying. The detonation wave generates pressure without compression.

so its an ice engine configured for hydrogen?

No. IC engines require compression. This does not.
