The main challenges to which the project aims to contribute are these: In order to achieve climate neutrality by 2050 and to achieve its targets for reducing greenhouse gas emissions from 2030, Wallonia wants to deploy technologies based on hydrogen from renewable energy sources, as indicated in the Walloon contribution to the National Energy and Climate Plan. In addition, Wallonia has companies that are active across the entire hydrogen value chain, with a very significant potential for economic growth and employment. The main challenges addressed by the project are reducing the carbon footprint of Walloon companies and industries in the transport or housing/services sector, creating jobs in this new branch, responding in a proportionate way to the need for flexibility that renewable energy sources and reducing, in the long term, our dependence on imported fossil fuels. This project should also contribute to the challenge of maintaining Wallonia&#39;s scientific, technical and industrial excellence.
