Technology Solution

Global annual installations of renewable energy, including wind power, are below half the level needed to get to an IPCC-compatible scenario to prevent global warming – costs need to come down and deployment needs to accelerate. Large wind turbine blades are 100m+ long, which causes tremendous forces on the blades and components, especially in high winds and storm conditions. Larger turbines create cheaper energy, but these forces mean blades have to be far heavier and more expensive as they get longer.

Brayfoil are building the future of wind turbine blades – patented biomimicryinspired compliant structures that change shape like a bird’s wings. The technology can be built into large wind turbine blades to reduce unnecessary loads, enabling larger, more efficient, more reliable and cheaper-per-MW devices. At turbine level, it can increase the annual clean energy production by enabling longer blades and fewer failures, and on an LCOE-driven level, this adaptive technology can increase wind turbine deployment – sites that would not previously have been viable for wind farms will be, thereby increasing the energy supply. With their first pilot turbine set to go on-site in mid-2022, the team welcomes partners and funders who align with their vision to help them accelerate wind power growth.

By going to market in 2026, this technology has the potential to reduce greenhouse gas emissions cumulatively by 43 gigatonnes of CO2 by 2050.
