This interactive policy sensitivity navigator explores how carbon constraints and Contract-for-Difference (CfD) support mechanisms influence hydrogen deployment in the Great Britain (GB) power system by 2050. Developed as part of the HI-ACT project on accelerated energy transition, the tool enables dynamic assessment of hydrogen integration pathways under varying policy and economic conditions.
The navigator allows users to examine a wide range of CO2 emission limits (0–500) and CfD support levels (0–250), and to assess their combined impact on system costs, emissions, and investment outcomes. Multiple hydrogen supply routes, including Grey H2, Blue H2, and Green H2, can be interactively enabled or disabled to reflect alternative decarbonization strategies.
Users can further explore the sensitivity of results across high and low investment assumptions and feedstock price scenarios, making the tool particularly useful for policy stress-testing and comparative analysis.
