GTA Electrolyzer Design
GTA has developed a breakthrough subsea electrolyzer platform built from commodity, corrosion-resistant materials. Instead of relying on scarce noble metals, GTA uses polyethylene housings, porous polyethylene sheets, nickel ribbon electrodes, and fiberglass-reinforced pipe—materials proven for long service life in harsh marine environments. The electrolyzers are modular, lightweight, and free of moving parts, ensuring low maintenance and high durability on the seafloor. Their design eliminates expensive titanium, iridium, and platinum components that dominate the cost structure of PEM systems. This engineering philosophy delivers a low-capex, high-reliability pathway to clean hydrogen at globally competitive prices.
Manufacturing & Supply Chain
GTA electrolyzers are designed for mass production using existing industrial processes. Injection molding, digital wire winding, and polymer fabrication enable large-scale manufacturing at low cost, without requiring specialized clean rooms or complex assembly steps. All core inputs—polyethylene, nickel, fiberglass—are widely available in competitive global markets, ensuring resilience against supply chain shocks. By contrast, PEM electrolyzers depend on iridium and platinum, metals with limited reserves and geographically concentrated production. GTA’s approach minimizes geopolitical risk, supports reshoring of U.S. clean energy manufacturing, and enables rapid expansion to gigawatt-scale capacity without supply bottlenecks.
