There's recently been lots of talk recently about the role of hydrogen in decarbonising energy systems. So, is the "hydrogen economy" back on the agenda? If so, how will hydrogen be produced and for which applications? Is it really low-carbon? 

In this latest chinwag, we briefly run through some of these questions and outline the key issues involved in taking hydrogen forwards; including how hydrogen might fit into the energy mix alongside other growing sectors such as offshore wind, and how it provides a way to decarbonise while linking the different sectors of power, transport and heat.
