Ansaldo, ok alle turbine alimentate a idrogeno e olio vegetale

Two independent validations have certified Ansaldo Energia's progress in using low-carbon fuel alternatives: Tüv Süd verified the Gt36 turbine's capability to use hydrogen, while Dnv validated the Ae94.3A turbine's operation on hydroprocessed vegetable oil (Hvo), a liquid fuel produced from organic raw materials. Tüv Süd's Hydrogen readiness certification confirms the Gt36 turbine's path towards operating with increasing concentrations of hydrogen, a significant step towards operating on 100% hydrogen.

The Gt36 is currently available with a hydrogen usage capacity of up to 70% by volume. As for the Ae94.3A gas turbine, Dnv's independent testing campaign at Sesta lab in Radicondoli (Italy) demonstrated successfully the hybrid liquid fuel combustion system fueled by Hvo under conditions representative of the turbine's actual operation.

The campaign confirmed stable combustion across the entire operating range without flashback events or interruptions during Hvo-only operation. Federico Bonzani, chief technology officer of Ansaldo Energia, emphasizes that fuel flexibility is one of the company's main strengths. Hydrogen and low-carbon fuels offer concrete paths to reduce CO2 emissions, valorizing existing plants and preserving the stability services guaranteed by rotating machines.

The expertise developed can be applied to both new installations and existing fleets through retrofitting interventions. Combined with upgrade packages and digital services, fuel flexibility represents a key element in the progressive decarbonization of electrical generation assets.
