Green hydrogen is a promising energy carrier that can grow into a new northern force and economic and social impact. Hydrogen is an important cross-sectoral integration theme in the Climate Agreement. Northern Netherlands has knowledge, skills and experience with natural gas and renewable energy. As a result, Northern Netherlands is relevant for the Dutch and North-West European energy supply. There is a commitment of the Northern Dutch industry, SMEs, knowledge institutions and government, with long-term cooperation between these parties, to develop this green hydrogen market. In order to ultimately legitimise the large-scale investment for the large-scale deployment, wider applications are needed that are physically developed in our region. Many industrial companies and SMEs are working to exploit the same market opportunities with hydrogen and find that they cannot do so alone. There is a need and willingness to cooperate and innovate in the pre-competitive playing field. Experience also shows that this type of cooperation does not go by itself. Mutual trust is important, as well as making the approach and results concrete by actively guiding the process. There are currently over 100 initiatives (ideas, plans and feasibility studies) in the field of water-dust, project overviews collected by the New Energy Coalition. Many of these require similar preparations, such as consortium formation, project development, planning and financing.In the North of the Netherlands, the HydroGreenn network with more than 15 companies interested in hydrogen was launched in mid-2017. They work short-cyclically on concrete issues and with natural decision-making moments to adjust, continue or stop. A lot is learned. This new form of cooperation, with the aim of exploiting the market opportunities of water dust, is successful. HydroGreenn’s method is unique (bottom-up, trust, open, concrete and short-cyclical, learning and doing) and has a suction effect on others. This method has also been translated into a collaborative project which resulted in a grant application to RVO. There is a lot of interest from market players in the North of the Netherlands to get started with hydrogen. A number of HydroGreenn members now want to harness the momentum by setting up the “Green Hydrogen Booster” to: 1.Connecting partnerships and initiatives, accelerating and sustainable innovation in the hydrogen chain through green hydrogen, and achieving sustainable growth and jobs.2. Creating an open innovation environment and promoting hydrogen to make the region an innovation ecosystem for the transition to green hydrogen.3.Providing an environment, knowledge and technology for professional education.Green hydrogen has the potential to be an important component for the energy supply of the whole of the Netherlands and Northwest Europe. In the North of the Netherlands, all elements are present to convert large-scale sustainable generation into hydrogen: large-scale production of offshore wind (this green electricity is an essential green raw material from which green hydrogen can be produced), high-voltage power supplies, power plants and knowledge and skills. The Green Hydrogen Booster is an initiative of a consortium of Hanze Hogeschool Groningen, Noorderpoort, VNO-NCW MKB Noord, New Energy Coalition, Stork-Fluor, Rendo, BAM Infra, DNV GL, KIWA, NAM, emmtec and TCNN. They make an investment and take the lead to create a state of the art and unique open innovation ecosystem that any industry, SME, government or knowledge and educational institution can participate in.
