Summary
• 100% hydrogen-capable turbines are expected to be commercially available by the early 2030s, carrying a CAPEX premium of approximately 10% relative to natural gas systems, increasing to around 20% for early deployments requiring power derating. Available evidence from early-stage projects, and OEM engagement indicates that power derating of between 10 – 20% could be required for initial deployments. These turbines offer flexible operation on hydrogen-natural gas blends and the capacity to operate on natural gas in the event of hydrogen fuel supply disruption.
• Turbines typically require natural gas for start-up, necessitating dual fuel infrastructure.
• Reciprocating engines, commercially available today for 100% hydrogen, typically carry a CAPEX uplift of 10–20% compared to natural gas equivalents but face significant power reductions when operating on blends, limiting their operational capacity in the event of hydrogen fuel supply disruption.
• Industrial combined heat and power (CHP) systems are typically developed at refineries or sites with local steam demand, presenting viable local decarbonisation opportunities, dependent on steam offtake, but with limited potential for extensive rollout.
• Fuel cells, despite high efficiency, face high CAPEX versus competing technologies. Future deployment hinges on capital cost reductions and high load factor applications to leverage efficiency benefits.
• Effective deployment of all grid-scale hydrogen to power technologies depends heavily on hydrogen storage, particularly geographically limited salt caverns, with storage needs rising significantly at high hydrogen blends, and the potential for dual-fuel flexibility to optimise storage use and system reliability.
• Coordinated policy and regulatory frameworks across hydrogen production, storage, and power generation are essential to manage risks and enable investment.
