Barbados has unveiled the world's first vehicle powered by renewable natural gas (RNG) derived from Sargassum seaweed, rum distillery wastewater, and Blackbelly sheep manure. This innovative project, led by the University of the West Indies (UWI) at Cave Hill and Rum and Sargassum Inc., aims to address environmental challenges and promote sustainable energy solutions.
The vehicle, showcased at Guinea Plantation in St. John, operates on bio-compressed natural gas (bio-CNG) produced through the co-digestion of Sargassum seaweed, rum distillery wastewater, and Blackbelly sheep manure. This process not only provides an alternative fuel source but also offers a sustainable method to manage the invasive Sargassum seaweed that has been affecting coastal regions.
Minister of Energy Lisa Cummins highlighted the significance of this development, emphasizing the potential of Sargassum as a valuable asset in Barbados' renewable energy transition. She noted that this initiative demonstrates the country's capability to lead in the renewable energy sector and serves as a model for the Caribbean region.
Dr. Legena Henry, founder of Rum and Sargassum Inc. and a lecturer in renewable energy at UWI Cave Hill, emphasized the project's potential to reduce fuel costs and carbon dioxide emissions. She stated that bio-CNG is an affordable solution that can help residents significantly lower their fuel expenses while contributing to environmental sustainability.
The project has garnered support from various stakeholders, including the Caribbean Centre for Renewable Energy and Energy Efficiency (CCREEE), which provided the electric vehicle for the test drive. Looking ahead, plans are underway to establish a biogas station, further integrating this renewable energy source into the country's infrastructure.
This initiative aligns with Barbados' goal of becoming a 100% renewable energy and carbon-neutral island state by 2030, showcasing the nation's commitment to sustainable development and innovative solutions to environmental challenges.
