Innovative energy generation for maritime operations
Modular, utility-grade floating solar arrays for reservoirs, harbors, and salt ponds. Low-cost, rapid‑deploy clean power near load centers.
Generate clean electricity from vessel loading operations and tidal cycles, providing renewable power for port operations and grid export.
Produce green hydrogen using renewable energy from maritime operations and floating solar. BlueSpan + CLER hybrids improve electrolyzer utilization and economics.
Convert green hydrogen into ammonia for cost-effective transport and export, creating a sustainable energy carrier solution.
Innovative approaches to maritime energy generation
Our proprietary Cargo-Loading Energy Recovery (CLER) system represents a targeted approach to port energy. Best applied at high‑throughput, high‑tidal‑range berths and when hybridized with BlueSpan to raise annual capacity factor.
