In order to reach TRL 7 at the end of the project, proposals should therefore include:

• Detailed simulations aimed to define the cogeneration system expected performances and the gas turbine durability (mean time between maintenance in terms of start-stop cycles number and fired hours);
• Development of dedicated safety and plant integration concepts to enable operation of the retrofit GT unit with up to 100% H2;
• Execution of a field test with a gas turbine equipped with DLE H2 system:
  • Availability of a gas turbine engine equipped with DLE H2 system;
  • Availability of required hydrogen amounts to conduit an engine test campaign with respective feed lines, storage system typically required;
  • System behaviour characterisation, including typical transient conditions of the gas turbine system operation (start-up ramp to full load, loads rejections, turndown limits);
  • Transient conditions characterisation, related to fuel composition variation;
  • Real system environment setup of acoustic damping systems;
  • Availability of a demo plant with a cogeneration system and possibility to perform multiple start-stop cycles;
• Evaluation of the legislative barriers, if any, of using co-generation systems including a gas turbine retrofitted with combustion systems able to operate with fuel compositions up to 100% hydrogen.

Considering the purpose of retrofitting the combustion system in existing gas turbines fleets for the hydrogen combustion, the targeted gas turbine size for cogeneration applications is at least 10 MWe.

A minimum number of 60 (not continuous) fired hours should be achieved, to properly cover the system behaviour characterisation, including typical transient conditions of gas turbine system operations.
