The North Sea can become Europe’s largest climate-neutral energy system by 2050. It can help deliver net zero by modernising existing assets, becoming a test bed for new technology, and enabling a new level of energy connectivity between European countries. Shallow waters and raging winds make the North Sea an ideal location for offshore wind, and the geology that kept natural gas in place for millions of years is the perfect place to bury carbon dioxide. There are challenges though. Its harsh weather and seabed conditions and tides create difficult infrastructure issues. However, overcoming these obstacles could see the North Sea become a beacon for change.
