HyPowerGT: Demonstrating a hydrogen-powered gas-turbine engine fuelled with up to 100% H2

At a glance


The HyPowerGT project aims at moving technological frontiers to enable gas turbines to operate on hydrogen without dilution. The core technology is a novel dry-low emission combustion technology (DLE H2) capable of handling mixtures of natural gas and hydrogen with concentrations up to 100% H2. Besides ensuring low emissions and high efficiency, the DLE H2 combustion technology offers fuel flexibility and response capability on a par with modern gas-turbine engines fired with natural gas.

The new technology will be fully retrofittable to existing gas turbines, thereby providing opportunities for refurbishing existing assets in industry (CHP) and offering new capacities in the power sector for load levelling the grid system (unregulated power) and for mechanical drives. The DLE H2 technology adheres to the strictest specifications for fuel flexibility, NOx emissions, ramp-up rate, and safety, stated in the Clean Hydrogen Partnership Strategic Research and Innovation Agenda 2021-2027.

System prototype. The new DLE H2 combustion technology will be further refined and matured and, towards the end of the project, demonstrated at TRL7 on a gas-turbine engine (NovaLTTM16 in the 16 MWe range), fired with fuel blends mixed with hydrogen from 0-100% H2. Within this wide range, emphasis is placed on meeting pre-set targets for (a) fuel flexibility and handling capabilities, (b) concentration of hydrogen fuel during the start-up phase, (c) ability to operate at varying hydrogen contents, (d) minimum ramp speed, and (e) safety aspects pertaining to any level with regard to related systems and applications targeting industrial gas-turbine engines in the 10-20 MWe class.
