Caribbean scientists are revolutionizing the way we view sargassum, a problematic seaweed that has plagued local tourism, by converting it into bio-compressed natural gas to fuel cars. This project, led by researchers at the University of the West Indies (UWI), aims to tackle an environmental challenge while also providing a solution to energy needs. The initiative gained momentum in 2011 when invasive sargassum began to wash up on the region's pristine beaches, leading to a national emergency declaration by Barbadian Prime Minister Mia Mottley in 2018.
From Burden to Breakthrough: Transforming Sargassum Seaweed into Sustainable Fuel
From Burden to Breakthrough: Transforming Sargassum Seaweed into Sustainable Fuel
An innovative project in Barbados is turning invasive sargassum seaweed into a biofuel, aiming to reshape the region's energy landscape.
Amid the overwhelming accumulation of this foul-smelling algae, a group of dedicated researchers, including Dr. Legena Henry and biologist Shamika Spencer, began investigating how to turn this environmental crisis into an opportunity for sustainable energy. By combining sargassum with wastewater from rum distilleries and indigenous sheep dung, the team was able to create an innovative biogas that promises to power local vehicles. The process is simple, with an installation cost of approximately $2,500, making it accessible for a wide array of vehicles.
The journey began when a student, Brittney McKenzie, suggested using the ubiquitous sargassum after observing the extensive efforts to remove it from beaches. This idea blossomed, leading to successful trials that caught the attention of investors, including the US non-profit Blue Chip Foundation, which pledged $100,000 to support their efforts. The project not only provides solutions to the seaweed crisis but also mitigates health risks associated with decomposing sargassum that emits hydrogen sulfide.
As the team strives to scale production, plans include establishing a biogas station that will enable sustained energy supply and possibly extend their innovative work into pest control products. This ambitious project not only aims to boost the local economy but also serves as a model for other regions similarly affected by sargassum, showcasing Caribbean ingenuity and resilience in facing the impacts of climate change.
