+945 TWh
AI doubles demand
Global data center electricity goes from 415 TWh (2024) to 945 TWh by 2030. Without efficiency gains, it is unsustainable for the grid and for operators' bottom line.
Solutions · Coastal data centers
Cool your data center with the sea. PUE 1.1, no biocides.
AI is driving up data center electricity demand. Marine cooling lowers PUE from 1.5 to 1.1, 80% less cooling consumption. The only barrier was biofouling. We eliminate it.

The problem
Data center cooling is unsustainable, and AI makes it worse
PUE 1.56
PUE stalled for 5 years
The industry's average PUE hasn't improved since 2020. Only hyperscalers reach 1.1, with CAPEX and locations most operators can't replicate.
under 0.1%
Marine cooling is blocked
Cooling with seawater would lower PUE to 1.1. But fewer than 0.1% of data centers use it, even though half are near the coast. The barrier is biofouling, not physics.
The solution
A submerged titanium box cooler. A single circuit.
The anti-biofouling titanium heat exchanger is submerged in the sea and dissipates the data center's heat directly. No chiller, no evaporative tower, no seawater pumps, no chemicals.
How the technology works- Eliminates biofouling without biocides, compliant with European regulation
- 95% less electricity dedicated to cooling
- Zero freshwater consumption, a critical ESG factor in water-stressed areas
- No cleaning shutdowns, critical uptime in Tier III/IV

Reference figures for a 1 MW data center. Assume €0.10/kWh (European average). In Ireland, with electricity at €0.20/kWh, savings double and payback drops below 3 months. With CAEs (Spain) or CEEs (France), net CAPEX can be almost fully covered.
Where
Spain, France and Ireland: the European triad
Three markets with differential levers that reduce validation risk.
Spain
CAEs
Energy Savings Certificates let operators monetize savings and cover nearly all CAPEX. Established operations + Mediterranean and Atlantic coastline.
France
CEEs
Europe's most mature CEE system, with standardized sheets (BAT-TH-156, IND-UT-135) that fund up to 100% of water freecooling in data centers.
Ireland
Grid + cold water
Europe's highest data center density (22% of national consumption). Cold Atlantic water year-round + a grid moratorium that makes low PUE a condition of viability.
