North Sea energy explained: oil, gas, wind and what comes next

A comprehensive primer on the UK North Sea energy landscape — from decades of oil and gas production to the rapid growth of offshore wind, hydrogen and carbon capture.
The North Sea story so far
- The UK Continental Shelf has produced over 45 billion barrels of oil equivalent since the 1970s — one of the most productive basins in the world.
- Peak production was around 4.5 million barrels of oil equivalent per day in 1999. Current production is approximately 1.3 million boe/day.
- An estimated 3-4 billion barrels of oil equivalent remain recoverable with current technology.
- Over 300 active offshore installations operate across the UK Continental Shelf, connected by thousands of kilometres of subsea pipelines.
The rise of offshore wind
- The UK is the world's second-largest offshore wind market after China, with over 14GW of installed capacity.
- Scotland has committed to 40GW of new offshore wind by 2040, with ScotWind and INTOG adding 23.5GW+ to the pipeline.
- Fixed-bottom wind farms dominate current installations, but floating wind is the growth frontier — enabling projects in deeper waters further offshore.
- Major projects include Dogger Bank (3.6GW), Hornsea One and Two (2.6GW combined), and the Moray and East Anglia hubs.
What comes next: hydrogen, CCS and beyond
- The North Sea is emerging as a hub for green hydrogen production, using offshore wind to power electrolysers.
- Carbon capture and storage (CCS) projects like Acorn and Northern Endurance aim to store CO2 in depleted North Sea reservoirs.
- The NSTA estimates that CCS could support up to 40,000 jobs by 2030 across the UK.
- The energy transition is not a simple swap — it requires new skills, new infrastructure and new ways of working across the entire marine economy.
