This partnership focuses on advancing renewable hydrogen production, storage, transport, and distribution technologies.
• Investment and Funding: The EU provides financial support for hydrogen projects through various instruments, including the Recovery and Resilience Facility and Important Projects of Common European Interest (IPCEIs). These initiatives aim to stimulate investment in hydrogen technologies across the entire value chain, from production to end-use applications.

Types of Hydrogen: Navigating the Color Spectrum

Hydrogen is not a primary energy source but an energy carrier, meaning it must be produced from other sources. The environmental impact of hydrogen production varies significantly depending on the method used, leading to a color-coded classification system:

• Green Hydrogen: Produced through electrolysis of water using renewable electricity sources like wind or solar power. This method has zero greenhouse gas emissions and is considered the most sustainable option.
• Blue Hydrogen: Produced from natural gas via steam methane reforming (SMR) or autothermal reforming (ATR), coupled with carbon capture and storage (CCS) technologies. While it reduces CO2 emissions compared to grey hydrogen, it still involves some greenhouse gas emissions and depends on the effectiveness of CCS.
• Grey Hydrogen: Produced from natural gas without carbon capture. This is the most common production method today, but it is also the most carbon-intensive, contributing significantly to greenhouse gas emissions.
• Turquoise Hydrogen: Produced through pyrolysis, using heat to break down natural gas into hydrogen and solid carbon. This method has the potential for lower emissions than grey hydrogen, provided the solid carbon is permanently stored or used.
• Pink/Yellow Hydrogen: Produced through electrolysis using electricity from nuclear power.
• Brown Hydrogen: Produced from coal gasification, a carbon-intensive process.

The EU is prioritizing the development of green hydrogen as the primary pathway to decarbonization, recognizing its long-term sustainability and alignment with climate neutrality goals. However, low-carbon hydrogen, including blue hydrogen, is considered a transitional energy source that can play a role in reducing emissions in the short to medium term.
