Assens Fjernvarme (Denmark) has supplemented their existing wood chip combined heat and power plant and an existing wind turbine with a solar cell system and an air to water heat pump system. This unique combination of renewable energy sources makes it possible to combine a low price for heat consumers with the production of green electricity when the electricity market needs electricity and purchase electricity from the electricity grid when there is a surplus of green electricity in the grid.
In 2003, a hydrogen strategy was developed by the Government of Aragon. Its main objective is the development of new hydrogen technologies integrated with renewable energies and the promotion of Aragon’s incorporation to economic activities related to the use of hydrogen as an energy vector. To that end, the organisation, management, and execution of a wide range of actions in order to generate, store and transport hydrogen for its use in fuel cells, in transport applications or for the generation of distributed energy is carried out. The Government of Aragon aims to encourage research, technological development, cogeneration and industrial adaptation, contributing to industrial modernisation and the improvement of competitiveness. The implantation of projects based on sustainable energies that provide technological innovation and promote the energetic and environmental sustainability are favoured. Nowadays there are 73 members of the hydrogen strategy which are part of its Board and they belong to different sectors of interest.
Over the past several years, the Northern Netherlands has accelerated its hydrogen project pipeline together with its ambitions of becoming the leading European hydrogen ecosystem. The Northern Netherlands has received recognition as the leading European Hydrogen Valley developing a full-fledged green hydrogen value chain. Furthermore, multinationals have increasingly committed to the Northern Netherlands as their hydrogen ecosystem of choice, and regional governments have increased their commitments to realize the Northern Netherlands hydrogen ecosystem.
Green industrial areas are an important part of the transition to a sustainable economic system. This case shows how local policymakers connect the local renewable energy ambitions to concrete activities on a nearby industrial park. The park and the municipality cooperate together to create a green industrial area.
The city of Neustrelitz is a very ambitious municipality, especially in the areas of renewable energies, climate protection, and digitization. The local public utility company (Stadtwerke Neustrelitz), the municipality and the State Centre for Renewable Energy MV work hand in hand to promote the sustainable development of the municipality. The new city strategy for 2025 “green smart digital” unites the visions of the local actors. The development and implementation of a green business park is a further component in the realisation of the city vision 2025.
In 2008, the Regional Municipality of Bornholm decided to become a 100% sustainable and CO2-neutral society in 2025, in which only sustainable and renewable energy is used. In 2019, already 60% of the island’s energy is produced fossil-free by using wind, sun and biomass power. The island’s green vision, big share of renewable energy, citizen and community involvement and replicability of the energy solution helped in winning the 2019 RESponsible Island Prize.
