Grid services are simulated with each country's data for 2017 for energy prices, grid services and wind power profiles from relevant wind parks. A novel metric is presented, the value of curtailed hydrogen, which is independent from several highly uncertain parameters such as electrolyser cost or hydrogen market price. Results indicate that grid services can monetise the unused spare capacity of electrolyser plants, improving their economy in the critical deployment phase. For most countries, up-regulation yields a value of curtailed hydrogen above 6 €/kg, over 3 times higher than the EU's 2030 price target (without incentives). However, countries with large hydro power resources such as Norway yield far lower results, below 2 €/kg. The value of curtailed hydrogen also decreases with hydrogen production, corresponding to the cases of symmetric and down-regulation.12641100enginfo:eu-repo/semantics/openAccessjournal article10.1016/j.ijhydene.2022.08.152HydrogenPower gridGrid balancing serviceElectrolyserFCRaFRRHydrogenPower gridGrid balancing serviceElectrolyserFCRaFRRRenewable Energy, Sustainability and the EnvironmentFuel TechnologyCondensed Matter PhysicsEnergy Engineering and Power TechnologySDG 7 - Affordable and Clean EnergyProject IDinfo:eu-repo/grantAgreement/EC/H2020/779469/EU/Hydrogen-Aeolic Energy with Optimised eLectrolysers Upstream of Substation/Haeolusinfo:eu-repo/grantAgreement/EC/H2020/779469/EU/Hydrogen-Aeolic Energy with Optimised eLectrolysers Upstream of Substation/HaeolusFunding InfoThis publication has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (now Clean Hydrogen Partnership) under the European Union's Horizon 2020 research and_x000D_ innovation programme under grant agreement No. 779469.
