The first Italian Hydrogen Valley will be built near Rome, at the ENEA Casaccia Research Center, and will take care of the energy vector at 360 degrees to shorten the distance that currently separates the most promising innovations from large-scale production. The project conceived by ENEA was born with an investment of 14 million euros (Mission Innovation funds) to create the first Italian technological incubator for the development of the hydrogen supply chain that takes care of the entire nascent supply chain (from production to distribution, from accumulation to use) in collaboration with universities, research institutes, associations and companies, with the aim of promoting the energy transition and decarbonisation.
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.
The GRENOBLE-ALPES-METROPOLIS district heating, with its 170 km of liquid pressurized
water distribution pipes, is the second largest District Heating System in France (900 GWh). The
district heating is a strong part of the energy strategy of the city. The integration of renewable and recovery energy accelerates and solutions are deployed to achieve
a 100% RE District Heating in 2033. State of the art solutions (biomass, waste heat from incineration
plant, geothermal energy) are combined with innovative solution (storage, CO2 capture, smart control) .
Odense wants to phase out the remaining 30% coal consumption in the heat
production for the district heating network by 2025. In 2018, the coal consumption was already reduced from ~900.000 t/y in 2010 to 2-300.000 t/y but the goal is to substitute this completely. To realize this purpose, electric heat pumps, large heat storages, biomass boilers, and electric boilers are constructed. The challenge is
to carry this out without price increases for the consumers, especially the greenhouse industry where
heat price is an important competition faction.
The City of Kortrijk installed a pilot heatnet at Kortrijk Weide, as a nucleus for further extensions in the city. The feasibility to install a heatnet backbone from the waste incinerator at the outskirts of the city, along the River Leie, to the city center was researched. As many building projects are taking place along the river, this would create the opportunity to connect over 1,000 households.
The biomass heating plant and district heating grid in Güttenbach (Austria) was built in 1997. The boilers are fired with wood chips from local forests. There are two boilers installed, one biomass boiler with 1 MW capacity and one oil boiler for peak load and backup with 1.3 MW capacity. The village of Güttenbach has about 900 inhabitants and an area of 16 km2. The district heating grid has a length of 12 km with about 240 connected consumers. Each year there are 5,200 MWh heat sold to the consumers.
