When we talk about the technologies the world will need to tackle climate change, low-carbon hydrogen is increasingly part of the discussion. Two recent studies raise some big questions about whether some of these hydrogen technologies are as climate-friendly as proponents claim. In this episode of ESG Insider, we look at the research and development of blue hydrogen, which is derived from natural gas and paired with carbon-capturing technology to reduce the resulting emissions. And we also examine what role green hydrogen, which is created using renewable generation to separate water molecules, could play. We talk with the authors of those two recent studies and we hear from a hydrogen expert at a European research institute about the current state of the industry and what role the government is playing in promoting these technologies.
