On 30th July 2024, the Spanish Ministry for the Ecological Transition and the Demographic Challenge (MITECO) announced a significant investment of €1.2 billion towards large renewable hydrogen valleys, commonly referred to as hydrogen clusters. This initiative aims to boost the development and growth of renewable hydrogen within Spain. The investment will be allocated through a competitive bidding process set to commence later in the same year, with the final winners expected to be revealed in the following years, 2025 and 2026. The support provided by MITECO will be in the form of capital grants specifically tailored for hydrogen producers. To further explain the core principles of this support scheme, ICIS has developed an informative infographic. This substantial financial backing signifies Spain's commitment to advancing the renewable energy sector and promoting the transition to cleaner energy sources. The investment is expected to drive innovation, foster job creation, and contribute to the country's overall environmental sustainability goals.
