Pilot project (2022 – 2024)
A pilot project was launched in Grenada to assess the feasibility of utilizing Sargassum seaweed for biogas and biofertilizer production. A biodigester was installed at True Blue Bay Resort, resulting in seven dissertation studies. These studies focused on various aspects of the project:

  • Two studies analyzed the quality and quantity of methane gas produced.
  • Two studies examined the quality of the biofertilizer derived from Sargassum.
  • One study explored the logistics of scaling the operation.
  • One study assessed the potential to connect the energy produced by the biodigester to Grenada’s national grid by generating electricity.
  • One study focused on the dimensioning and establishment of the scaled-up facility.

 



 

    Scaled up facility (2025)
    We are setting up a scaled-up facility at Telescope, St. Andrew’s (on the east coast of Grenada) to produce biogas and biofertilizer from sargassum. The biogas is used to generate electricity (150kW) which is fed to the electric grid and bio fertilizer is transported to large-scale agriculture customers.
  • Renewable energy solution: We provide a stable, predictable renewable energy source to complement intermittent energy in the future energy mix.
  • High electricity costs: Grenada’s average electricity cost is $0.30/kWh, presenting a strong business case for biogas-based electricity generation.
  • Favorable regulatory environment: Grenada’s restructured regulatory framework prioritizes sustainability and encourages competition, supporting our operations.
  • Pending application: In Q4 2024, we are applying for an Independent Power Producer (IPP) license under the Public Utilities Regulatory Commission (PURC) to establish a large-scale electricity production facility using Sargassum-derived biogas.




Large scale facilities (2026 – )
Starting in 2026 and beyond, we will expand and replicate our solution in Grenada, across the Caribbean, and in regions of North and South America affected by Sargassum seaweed, bringing our innovative approach to new markets worldwide. The goal is to install 20MW of Sargassum-derived electricity in the whole region.
