Proposal for a 100,000 Mt-day Seawater Desalination - LNG

Executive Summary

Geodyn Solutions proposes a 100,000 Mt/day (100,000 m³/day) seawater desalination plant in North Jakarta, Indonesia, powered by a self-reliant 40 MW LNG plant with Organic Rank- ine Cycle (ORC) and Heat Recovery Boiler (HRB). Using enhanced GeoRO™, GeoGraphene™, GeoHybrid™, GeoForward™, and GeoZero™ technologies, the plant maximizes efficiency and sustainability. GeoZero™ recovers 1,500 tons/day of salts for fertilizers and commodities, gen- erating $64.20M/year net profit. With a 30% contingency, 0% Bappenas loans, World Bank grants, and BKPM tax incentives, it achieves a 10-year ROI of 141.40 %, creates 880–1,180 jobs, and aligns with Indonesia’s water security goals.
