Improved electrolysis for Distributed Hydrogen production

 

Proposal must address the following objectives:

  • Development of electrolysers from 100 to 500 kW to provide grid services. Fact based assessment of specifications, supported by experimental evidences (i.e. from existing facilities, especially interaction with the grid and renewable electricity sources), is highly valuable
  • System and component optimization for partial load operation, from 20% (with a minimum efficiency of 50%) to 120%
  • System and component optimization for highly dynamic operation
    • ramp-up rates of less than 2 seconds going from 20% to 100% of nominal power,
    • warm start-up
    • cold start-up
    • standby behaviour, i.e. maximum of 5% of nominal power in standby mode
  • Control system designed to enhance interaction with the grid and renewable sources

Proposals could address the additional following objectives:

  • System engineering and improvements i

    Implemented energy policies have the objective of producing 65% of electricity from renewable energy sources by 2050, and of reducing emissions of CO2 linked to energy production by 50%.

    The rapid deployment of wind power and solar energy sources contribute to reducing the carbon footprint of the electricity grid. However, wind power and solar energy are resources dependent on meteorological conditions and their instability poses a number of problems for functioning of the electrical grid, in terms of stabilisation mechanisms, regulation and offsetting. The bottlenecks in the electricity supply system result from an excess of renewable energy which cannot be transferred to the grid and that is consequently curtailed by the operators of the supply grid, in order to balance the power produced and demand for energy and/or to permit the allocation of electricity deriving from other sources

    Considerable investments in transport and distribution infrastructure will be necessary in the fort

    • Address business cases and applications where the Distributed Hydrogen Production may have a significant impact
    • As reported in the MAWP, target KPIs on cost per nominal power for alkaline and PEM electrolysers will be considered
    • Contribution to achieve KPIs of the “Electrolysis Study” from FCH 2 JU, decreasing electricity consumption to 52 kWh/kg H2 for alkaline electrolysers and 48 kWh/kg H2 for PEM electrolysers, and capital cost to 630 EUR/kW for alkaline electrolysers and 1,000 EUR/kW for PEM electrolysers)
    • Setting up innovative solutions and configurations for grid and renewable energy integration, implemented of control systems fully adapted to provide grid services
    • Involvement of policy makers to develop regulations for grid services provided by electrolysers in the EU member states
