Proposal: Geodyn Solutions 100 MW Algae Biogas & Circular Bioeconomy Plant – Puerto Rico
Executive Summary
Geodyn Solutions proposes a 100 MW algae-based biogas power plant in Puerto Rico, designed around a circular bioeconomy that produces renewable electricity, organic fertilizer, and high-protein algae biomass for food and feed. Using open pond algae cultivation and anaerobic digestion, the project maximizes ROI through multiple revenue streams while contributing to Puerto Rico’s energy independence, agricultural sustainability, and environmental goals.
This model offers low-cost, land-based deployment, exceptional carbon sequestration potential, and a 12-year ROI of nearly 300%, making it one of the most financially and ecologically attractive clean energy projects available.

Annual Output & Revenue Streams
- Electricity Sales
- Annual Output: 100 MW × 85% capacity × 8,760 hours = 744.6 GWh
- Revenue: 744.6M kWh × $0.19 = $141.47 million/year
- Organic Fertilizer Sales
- Digestate Output: ~200,000 tons/year
- Revenue: $100/ton = $20 million/year
- Algae Protein (Food/Feed) Sales
- Dry Biomass Output: ~10,000 tons/year
- Revenue: $2,500/ton = $25 million/year
Total Annual Revenue:
$141.47M (Electricity) + $20M (Fertilizer) + $25M (Algae) = $186.47 million/year
