This study determines the cost reducing effect of hydrogen supply-push targets, which will indicate the sufficiency of current UK government policy to initiate a hydrogen economy within the industrial sector. This study will also answer the question “What demand-pull policies can support fuel switching to hydrogen in UK industry?” A novel mixed-methods approach is used, in-depth rapid evidence assessment and a macro market penetration assessment to understand how to best establish an industrial hydrogen economy. Our findings show that without demand-pull policies, 65 GW to 350 GW of hydrogen supply is required to achieve price parity with natural gas.
