Eccentric-looking they may be, but ultra-large two-bladed turbines promise to generate at a levelised cost of energy (LCoE) that is as much as 50% lower than current offshore designs — a massive step towards making offshore wind competitive with other energy sources.
“If the improvement in cost of energy is of the magnitude we are calculating, major developers will be forced to see the commercial logic of two-bladers,” says Martin Jakubowski, chief executive of Italian turbine designer Condor Wind.
