While the direct use of hydrogen in many of the applications discussed in this ‘Grid Balancing and Energy Security’ issue is often seen as the end goal, there has been growing excitement over the prospect of blending hydrogen with natural gas as an interim step to lower emissions in the shorter term.
In theory, blending the two gases will lower the emissions from natural gas grids while allowing existing infrastructure to be used, serving end-users where electrification is uneconomic.
From boilers and gas turbines to industrial processes and more, the idea of blending has been bounced around in a variety of geographies, with many policy-led projects exploring the pathway’s potential.
