H2U Hydrogen Valley – Reni

The technical and economic calculations for building a renewable hydrogen production plant near the city of Reni in the Odesa region have been completed. An assessment of regional renewable energy potentials has been performed. The possibilities of constructing a plant with installed electrolyzer capacities in phases: 100 MW, 200 MW, and subsequently upscaling to a larger capacity have been considered.

The regional water resources, including those of the Danube River, are more than sufficient to supply water to the plant of the considered size without creating any water deficit. The front-end engineering design has been completed on the designated land plot, considering the possibility of constructing a plant with an initial electrolyzer capacity of 100 MW, with the potential for scaling up to 200 MW. An assessment of the technical feasibility of constructing renewable energy sources (wind and solar power plants) with a total capacity of two phases – 400 MW, for the purpose of electric power supply for hydrogen production by electrolysis, has been carried out.

The project has been officially recognized and certified by Mission Innovation and the Clean Hydrogen Partnership, and published on the Mission Innovation Hydrogen Valley Platform 2.0 for hydrogen project developers, which was launched on May 8, 2023, to showcase flagship hydrogen projects worldwide.


H2U Hydrogen Valley – Zakarpattia

The renewable hydrogen production plant in the Zakarpattia region is planned to be built on the territory of Velykodobronska local community, Uzhhorod district, Zakarpattia Region. The site for the project is located near high-voltage electrical networks, water sources for electrolysis, and pipeline of the existing gas transmission system of Ukraine.

The initial phase of the project involves creating a small-scale local hydrogen value chain, while subsequent phases include large-scale hydrogen production with electrolyzer capacity starting from 100 MW to 1.5 GW and creating a hydrogen transportation corridor from Ukraine to US Steel Košice in Slovakia, followed by the scaling of this hydrogen corridor to other Central European countries.

This project is part of the cross-border Slovak-Ukrainian hydrogen valley EastGateH2EU Hydrogen Valley, which serve as a key element for large-scale hydrogen production and its transportation from Ukraine to the EU via the Central European Hydrogen Corridor (a modified pipeline stretching from Ukraine to Slovakia, the Czech Republic, Austria, and Germany).

In November 2023, the project was certified by Mission Innovation and the Clean Hydrogen Partnership and published on the Mission Innovation Hydrogen Valley Platform.
