lds and offshore wind developments on the UK continental shelf
Replacing the UK gas supply with hydrogen will require ~150 TWh of seasonal storage capacity
We calculate a P50 value of 6900 TWh of hydrogen working gas capacity in natural gas
fields and 2200 TWh in porous saline formations on the UK continental shelf
Most of this capacity is located in natural gas fields in the Southern North Sea where existing infrastructure and several GW of existing and planned offshore wind developments could be
utilised to develop large-scale offshore hydrogen production.

UK gas supply
Highly seasonal with over 70% from UK and Norway gas fields1
Total above average demand in winter of 2017/18
was 133.5 TWh
2018 UK gas demand was 881 TWh2
Seasonal hydrogen storage requirement:
This study calculates
at least 133.5 TWh
Energy Research Partnership (ERP) study3 implies ~150 TWh
