The global energy system is transforming towards renewable production, with large scale build-out of solar and wind generation on a commercial basis. However, the intermittency of wind and solar is a major problem. To achieve a fully renewable system that is both secure and affordable, other components such as storage and predictable energy generation must be added to the mix. The Deep Green technology, developed by Minesto, offers a novel solution to this challenge. It produces electricity from 100% predictable slow tides and ocean currents , using less material and benefitting from cost-effective installation and operations compared with competing technologies.
