Our Solutions

Innovative energy generation for maritime operations

BlueSpan Floating Solar

Modular, utility-grade floating solar arrays for reservoirs, harbors, and salt ponds. Low-cost, rapid‑deploy clean power near load centers.

  • Optimized 15% water coverage with light‑gap patterns
  • Reduced evaporation and improved water quality
  • Scalable hub‑and‑spoke electrical architecture

Electricity Generation

Generate clean electricity from vessel loading operations and tidal cycles, providing renewable power for port operations and grid export.

  • Renewable energy from vessel operations
  • Grid integration and export capabilities
  • Frequency regulation and demand response
  • Energy storage and management systems

Hydrogen Production

Produce green hydrogen using renewable energy from maritime operations and floating solar. BlueSpan + CLER hybrids improve electrolyzer utilization and economics.

  • PEM and P‑AEM electrolysis, grid‑synchronized
  • Compression, storage, and balance‑of‑plant
  • Refueling and export options
  • R&D: HydraFilm‑X thin‑film electrolyzer (lab prototyping; no performance claims)

Ammonia Synthesis

Convert green hydrogen into ammonia for cost-effective transport and export, creating a sustainable energy carrier solution.

  • Ammonia synthesis from green hydrogen
  • Cost-effective transport solution
  • Established chemical transport infrastructure
  • International export capabilities

Our Technology

Innovative approaches to maritime energy generation

CLER Technology

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.

Methodology

Assumptions and calculation approach for published figures

BlueSpan (Floating Solar)

  • Global plan derived from regional targets.
  • Capacity factor (CF) set per region; nameplate computed as MWp = (TWh × 1e6) / (CF × 8,760).
  • Power density: 60 MWp per km² of PV rafts; PV raft area = MWp / 60.
  • Strict environmental guardrail: ≤15% coverage per water body; water area needed = PV raft area / 0.15.
  • Average capacity (GW) = Annual generation (TWh) / 8.76.
  • Economic examples use electricity price deck AUD 70–100/MWh and PV capex $0.60/W for ROI ranges.
  • Regional water‑area availability to be validated; plans will be scaled to honor the ≤15% cap everywhere.

CLER (Cargo‑Loading Energy Recovery)

  • Physics‑based, displacement‑capped flow model using P = ρ g Q H η, limited by vessel throughput, berth occupancy, and tide.
  • Per‑berth nameplate and CF are site‑specific; figures depend on verified traffic, tidal range, and hydraulic design.
  • CLER hybridization with BlueSpan is favored to raise utilization and improve economics.

Note: We will update figures as regional reservoir/lake areas are confirmed and CLER site models are validated. All deployments will adhere to the ≤15% surface coverage constraint per water body.
