The Role of Hydrogen Emissions for a Climate-neutral Industry
Hydrogen is an important energy carrier that will be essential for decarbonizing our economies, in particular for industrial sectors like steel and chemical production. But hydrogen itself is an indirect greenhouse gas (GHG), and emissions along the hydrogen value chain – including those of methane and CO2 if blue hydrogen is part of the mix – have the potential to reduce the climate benefits of hydrogen if not properly managed. In a recent study, we evaluated the potential impact of climate-warming emissions in Germany’s future hydrogen economy and provide recommendations for German and EU policymakers on how to avoid them.
