A UK-based startup has taken a significant step toward commercialising a novel approach to green hydrogen production at sea. DRIFT Energy has received approval in principle from classification society RINA for a ship design capable of harvesting energy while underway and using it to produce hydrogen fuel onboard.
According to Ship & Bunker, the approval was presented during the Seatrade Cruise Global event in Miami. RINA noted in a statement that this is believed to be the first approval in principle ever issued for an energy-harvesting vessel concept of this kind.
How the Technology Works
As reported by Ship & Bunker, DRIFT’s vessel design centres on hydro-kinetic turbines fitted beneath the hull. While the ship is at sea, these turbines generate electricity, which is then used to produce hydrogen through electrolysis. The hydrogen is stored onboard and delivered to ports and coastal users upon arrival.
To maximise the amount of energy generated during each voyage, DRIFT uses an AI-powered routing system called Goldilocks. The system is designed to guide vessels along weather patterns that offer optimal conditions for energy harvesting.
Fleet Ambitions
DRIFT has stated that its first vessel is planned for launch in 2027. The company also reports having secured orders for more than 30 ships, signalling early commercial interest in the concept.
Does This Matter to You?
For those operating in the bunkering and maritime fuel supply sector, this development is worth monitoring. If DRIFT’s model moves toward commercial scale, it introduces a new category of vessel capable of producing and delivering hydrogen directly to ports — potentially offering an additional supply channel for alternative fuels at the quayside.
Port operators, fuel traders, and vessel operators exploring hydrogen as part of their decarbonisation strategies may find this technology relevant as the energy transition continues to reshape fuel sourcing and supply infrastructure. The receipt of formal approval in principle from a recognised classification society marks a concrete step beyond the concept stage.
That said, commercial viability at scale remains to be demonstrated, and the first vessel is not expected to launch until 2027.
