Hydrogen has a well-established, if limited, role in the modern economy. It has been used in refining and ammonia production for decades, but its potential has long been touted in various areas, including decarbonizing hard-to-abate industrial processes such as steelmaking, as well as in larger roles in heavy-duty transportation and energy storage. The last few years have seen a significant push to expand hydrogen’s role — an attempt to capitalize on its versatility and lack of carbon dioxide (CO2) emissions —  but a number of formidable obstacles to wider adoption remain, including price, availability and infrastructure, in addition to its tenuous political support. In today’s RBN blog, we look at the challenges that make forecasting the industry’s growth difficult and the emerging consensus around the most practical end uses for hydrogen.
