aviation

Sustainable aviation fuel (SAF) can reduce carbon dioxide emissions by up to 80% compared to conventional jet fuel.

Learn about our solutions

Aviation accounts for 2.5% of global CO₂ emissions.

While other sectors are decarbonizing, aviation remains hard to abate. Sustainable aviation fuel (SAF) offers a proven, scalable path forward – but only when produced with clean hydrogen.

Clean hydrogen unlocks low-carbon SAF.

Today’s SAF technologies rely on hydrogen as a critical feedstock. By replacing fossil-based hydrogen with renewable, electrolytic hydrogen, we can drastically cut the carbon intensity of SAF production.

Our electrolyser technology is the future of sustainable aviation fuel production.

MC Series

PEM Electrolysers

  • High-purity hydrogen for synthetic fuels: PEM electrolysers deliver ultra-pure hydrogen using only water and renewable electricity – ideal for SAF pathways such as Fischer–Tropsch or alcohol-to-jet, where fuel quality is critical.
  • Modular and scalable systems: Whether you’re piloting Power-to-Liquid production or scaling for commercial SAF supply, PEM electrolysers provide the flexibility to grow alongside demand.
  • Designed for dynamic operation: PEM technology is well-suited to renewable-powered SAF production, handling variable loads with high responsiveness and consistent output.

A Series

Alkaline Electrolysers

  • Proven, cost-effective hydrogen supply: Alkaline electrolysers are a mature technology for large-scale hydrogen production, offering a dependable and affordable solution for SAF developers.
  • Stable performance at scale: Ideal for steady-state SAF production, alkaline systems provide reliable hydrogen flow into fuel synthesis processes with minimal disruption.
  • Optimised for large-volume projects: With high efficiency and low operating costs, alkaline electrolysers make green hydrogen accessible for SAF production at industrial scale.
