Production of low or zero-carbon hydrogen on an industrial scale needs to be built in tandem with the emerging sources of demand across the economy. The ultimate goal is to be able to create hydrogen on a cost-competitive basis with grey hydrogen, which uses a carbon-intensive methane steam reforming process and currently dominates industrial supply, as well as conventional fuels/sources for power generation. 

The panel discussed the viability of different sources of hydrogen supply, energy storage solutions and renewable power generation, including from wind farms. It will consider recent technological developments and remaining challenges, as well as the economic and legal foundations necessary to facilitate its widespread adoption.
