Warmtenetwerk Zaanstad B.V. has created the first open district heating network in the Netherlands in Zaanstad-Oost. This organization is a partnership between the municipality of Zaanstad, Firan, and the provincial authority of Noord-Holland. Thanks to the open structure, all suppliers and customers will ultimately be able to use the heating infrastructure under the same conditions. The district heating network, which has supplied heat to an existing residential district since 2019, is powered by a local small-scale biomass plant in this early phase. In the future, we will also be able to connect newly constructed homes and create links for new products, suppliers and users.
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.
The Municipality of Goeree-Overflakkee aims to be energy-neutral in 2020 through the use of wind energy. They want to proactively move away from natural gas and to be a model location for sustainable energy solutions. Stad aan ‘t Haringvliet has been designated as a pilot location. After research, it became clear that all-electricity is difficult and inefficient and that connecting households at natural moments gives the best result in terms of sustainability. Stedin has also indicated that the natural gas grid is suitable for hydrogen and that the estimated costs of this solution are lower than an all-electric solution that involves reinforcing the electricity grid. So why not switch to hydrogen straight away?
The Brescia Province (Italy) is an area with major superficial aquifers and geological irregularity. This allows the exploitation of a geothermal source. Analysis of the results achieved by Cogeme SpA in the research of deep geothermal fluids and in the prototyping of “cold district heating” network systems allowing a rational use of groundwater for energy purposes.
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.
The ENNSHAFEN port, located in Enns, is the newest and most modern public port in Austria. Several local stakeholders are committed to invest in various types of energy cooperation: PV modules on (large) company roofs or other areas at the Ennshafen site, utilization of waste heat flux at Ennshafen between relevant companies, cooperation of companies regarding electricity (supply and demand) and gas (supply and demand), and electrification of the power supply of anchored
An interesting energy cooperation solution can be found in Tuscany, where one can find an industrial area mainly composed of several tanneries and a shared
wastewater treatment plant, managed by Cuoiodepur. Several local stakeholders agreed on the following principles:
1.) Energy cooperation is considered as a chance to highlight the efforts of industrial park towards a low carbon economy.
2.) Reduction of energy costs.
3.) Energy autonomy in order to avoid the risks associated with the volatility of energy prices and enhance the use of potential energy.
4.) A more economic and environmentally sustainable management of solid and liquid waste.
