Barbados is poised to make history with the launch of the world’s first vehicle powered by renewable natural gas (RNG) derived from Sargassum seaweed, Blackbelly sheep manure, and rum distillery wastewater. This innovative project, a result of over a year of research by the University of the West Indies at Cave Hill, marks a major step in renewable energy development.
The initiative, spearheaded by Rum and Sargassum Incorporated and Supernova Lab of Future Barbados, has attracted over $1 million in investments. The unveiling of Test Drive Zero, set to take place at Guinea Plantation in St. John, is a significant milestone in the island’s push for sustainable energy solutions.

According to Dr. Heidi Jack, the event will highlight various uses of RNG, including cooking, electricity generation, and powering vehicles. Attendees will witness the test drive of an electric vehicle fueled by RNG, as well as showcases of RNG-ready vehicles.
Dr. Legena Henry, a mechanical engineer and lecturer in renewable energy at UWI Cave Hill, emphasized the cost-saving potential of the initiative. “Bio-CNG is an affordable solution that can help Bajans cut their gas bills by 50 percent,” she said. “Car owners can keep their vehicles while benefiting from this locally sourced renewable fuel, derived from waste products like rum distillery wastewater, Blackbelly sheep manure, and Sargassum seaweed.”

Plans are underway for a biogas refueling station, with the long-term goal of enhancing the island’s natural gas supply, supporting the electricity grid, and providing liquified natural gas for export. The project is also aimed at addressing waste management challenges and supporting the country’s goal of becoming fossil-fuel-free by 2030.
Dr. Henry noted that if vehicles were to switch from gasoline to Bio-CNG, it could remove 103,000 metric tonnes of carbon dioxide emissions annually. The venture has received significant funding, including $200,000 from the Blue Chip Foundation, $200,000 from Venture for Climate Tech, and $600,000 from the European Union.

Looking ahead, there are plans to establish a network of eco-stations across the island, enabling motorists to refuel with biogas just as they would at a conventional petrol station. Dr. Henry’s research continues to explore ways to harness natural resources from the Caribbean Sea, such as Sargassum seaweed and ocean waves, for sustainable power generation.
