BalticSeaH2 will establish the first, largescale interregional hydrogen valley in Europe. BalticSeaH2 will build a main cross-border Hydrogen Valley between Finland and Estonia and connects it with local valleys in different countries surrounding the Baltic Sea. The ultimate goal is to develop an international hydrogen economy and markets that work optimally both from the technical, economic and environmental perspectives across country borders in the Northern Europe, more specifically around the Baltic Sea. The project will develop, scale and demonstrate hydrogen use in production, storage and distribution, and in Use Cases in different sectors from industry, mobility and energy. The learnings from the cross-border build-up of a hydrogen economy will be shared with specifically identified Connected Valleys and replicated across borders between them, but furthermore, shared to boost replication and initiate new hydrogen valleys across Europe. The cross border Main Valley is to be located in the region of Southern Finland – Estonia. These regions are already connected with a natural gas pipeline, transmission cable and maritime operations and the Transmission System Operators (TSO) in both countries collaborate actively in the further development of the cross border infrastructures. The cross border nature of the Main Valley makes is possible to develop cross border markets and businesses for green hydrogen production, transport and use from the start, including also development of cross border neighbouring pricing zones for renewable electricity to reach optimized system, market and business designs for an efficient hydrogen economy.

The CoordiNet Innovation Action proposal aims to demonstrate how DSOs and TSOs shall act in a coordinated manner to procure grid services in the most reliable and efficient way through the implementation of three large scale “TSO-DSO-Consumer” demonstrations, in cooperation with market participants (and end users). The consortium will define or adapt, demonstrate and promote future standardized grid services and related market platforms to enable a seamless pan-European electricity market. The CoordiNet consortium under the coordination of ENDESA is composed of 23 beneficiaries and 10 linked third parties from 10 different European countries. It is supported by an Advisory Board and a Stakeholders’ Forum to liaise with on-going projects in Europe and beyond. Three complete value chains of TSO-DSO-market participants constitute the backbone of the project in three demonstration macro-areas (Spain, Sweden, Greece) with ten demonstration pilots (four in Spain, four in Sweden and two in Greece) representing various boundary grid, climatic, load and generation conditions. Next to the demonstration campaigns, promising game-changer enabling technologies, such as IoT, Artificial Intelligence, Big data services, P2P energy trading platforms, Blockchain, Distributed ledger Technologies will be tested to explore alternative means to facilitate energy prosumers participation of small-scale energy consumers into the markets. Over the CoordiNet demonstration areas, the extent of demonstrations provides high level of added value to extrapolate features of TSO-DSO-market collaboration on a European wide-area through the set of standardized products that will be defined and field-tested and the building blocks for a future European platform that will contribute to opening new revenue streams for consumers providing grid services. Finally, the project will provide a pathway towards a seamless pan-European electricity market with non-discriminatory access to all market participants.
