For a technology that is essentially still in a pre-commercial phase, the expectation is high for floating wind to be the future of the offshore wind industry. But the technology landscape that is going to help floating scale is far from settled. With vertical axis wind turbines having been around for just as long as horizontal axis ones, floating also presents an opportunity for vertical turbines to play a bigger part. To discuss how the floating offshore wind sector has evolved, and the role that vertical axis turbines can have in the growth of this market, David spoke with Johan Sandberg, CEO of SeaTwirl.
