DRIFT Energy, a UK startup based in Bath, is pioneering the development of a 60-meter catamaran that can generate and store green hydrogen while sailing. The company's innovative approach has won the UK's 2025 Startups 100 Sustainability Award for its commitment to combating climate change and offering scalable alternatives to fossil fuels. Using wind power and hydrogeneration, the catamaran collects saltwater, purifies it, and then utilizes electrolysis to separate it into oxygen and hydrogen. This process results in 'green' hydrogen, considered the cleanest form of fuel produced solely from renewable energy sources. DRIFT Energy's founder, Ben Medland, was inspired to create this concept when exploring ways to make renewable energy generation more weather-responsive. The company's vessels are designed to travel at speeds up to 25 knots, producing green hydrogen efficiently and effectively. The vessels are equipped with a unique routing algorithm, Goldilocks, which utilizes artificial intelligence to optimize energy production and ensure timely return to port once the hydrogen tanks are full. This mobility allows the ships to deliver energy wherever needed, making them highly versatile and advantageous especially for island nations lacking traditional energy resources. With an initial funding round of £4.65 million, DRIFT Energy is progressing towards launching their first catamaran by 2027. The vessels will be operated initially by professional sailors for performance evaluation in various conditions before transitioning to autonomous operation. DRIFT Energy's innovative approach to harnessing wind power for green hydrogen production has been well-received, highlighting its potential to revolutionize the maritime industry and contribute significantly to the global shift towards sustainable energy solutions.
