ansaldo gas combustion technology

Norwegian multinational energy companies Ansaldo Energia and Equinor have announced a cooperation agreement to advance hydrogen combustion technology through full-scale, full-pressure burner verification testing. To accomplish the goals of the Paris contract, decarbonization in the power generation sector is crucial. The main challenge of hydrogen combustion compared to natural gas is a rise in reactivity, ensure in a reduction in engine production of conventional premixed ignition systems.

Hydrogen gas turbines enable configurable power generation without carbon dioxide (CO2). Hydrogen without CO2 can be produced by electrolysis (green hydrogen) using renewable energy, or it can be produced from natural gas (blue hydrogen) using dedicated CCS technology. As per Ansaldo Energia statements that its GT36 and GT26 gas turbines get the best of this drawback and can utilize all ranges of hydrogen in low NOx premixed ignition systems. The GT36 Class H gas turbine burner operates in natural gas with a volumetric hydrogen content of 0 to 50%. Recent comprehensive high-pressure experiments have shown that it is feasible to operate up to 70% hydrogen without reducing power efficiency, and it is possible to burn up to 100% hydrogen.

The two companies said that the cooperation between Ansaldo Energia and Equinor will further change this fuel flexibility function. The main target is to improve ultra-low NOx emissions, operational workability and minimalize engine derating at huge hydrogen levels. Equinor co-sponsored is the hydrogen testing activities of these combustion chambers.
