Revolutionary research reveals concrete foundations superior to steel for North Sea floating offshore wind projects, offering enhanced durability & 15-20% cost savings. The breakthrough enables access to deeper waters beyond 50 meters where stronger winds generate double the energy capacity. Concrete's corrosion resistance reduces maintenance costs by 40% over 25-year lifecycles while supporting local manufacturing. This technological advance could unlock 30 GW North Sea capacity by 2050, accelerating global floating wind growth from current 270 MW to gigawatt levels by 2026.
