Summary

Real hydrogen turbine hardware is moving. GE Vernova secured its first 100% hydrogen aeroderivative order and is testing at scale in Texas. Japan launched its first commercial 30% hydrogen turbine. The technology works; the constraint is hydrogen supply infrastructure, not turbine readiness.

GE Vernova - First 100% Hydrogen Order

• Order from ATCO Australia for four LM6000VELOX units.
• Destination: 200 MW Whyalla hydrogen power plant, South Australia.
• Commissioning expected early 2026.
• First time a GE Vernova power plant project at commercial scale is powered by aeroderivative combustion technology capable of operating on 100% hydrogen.
• In January 2026, GE Vernova initiated full-scale testing of 100% hydrogen-capable aeroderivative gas turbines at a pilot facility in Texas.

Japan - First Commercial 30% Hydrogen Turbine

• Japan launched the first commercial engine capable of generating electricity with 30% hydrogen.
• Described as “a step that seemed impossible just a few years ago.”

KIT Germany - Compressorless Hydrogen Turbine

• Karlsruhe Institute of Technology achieved a runtime record and first electricity generation with a compressorless hydrogen gas turbine.
• Research-stage, not commercial, but a novel approach.

Siemens Energy + Kawasaki Heavy Industries

• Joint development agreement (announced March 2025) to accelerate commercialization of hydrogen-ready gas turbines for large-scale power plants.
• Joint testing and pilot deployments planned for 2026.

Hanwha

• Hanwha created a new global compressor and gas turbine business unit (March 2026), signaling entry into this market as a fourth OEM.

Market Size

• Hydrogen gas turbine market projected to reach $3.47 billion by 2032.
• 16.5% CAGR between 2026 and 2033.
• North America leads with 35% market share.
• Key players: GE Vernova, Mitsubishi Power, Siemens Energy.

Our Thinking (2026-04-05)

The hydrogen turbine story splits into two timeframes:

Now (2026-2028): Single-site demonstrations. GE Vernova Whyalla is the flagship. Japan’s 30% commercial unit proves the lower blend works. But these are all at sites where hydrogen supply was specifically arranged. They don’t represent fleet-wide adoption.

Later (2028-2035): Fleet conversion depends entirely on hydrogen supply infrastructure (production, transport, storage). The turbines are ready; the fuel is not. Mitsubishi’s roadmap (30% in 2025, 100% by 2035) is technically feasible but requires a hydrogen supply chain that does not exist today.

New character: Hanwha. Their entry as a fourth OEM in gas turbines could eventually add manufacturing capacity to the supply-constrained market. Worth monitoring.

The case for commercial blending staying below 30% through 2030 is holding but under pressure. Japan hit 30% commercially, so the “below 30%” language may need updating. The real question is what percentage of the installed fleet runs any hydrogen at all, not what individual units can do.
