Maritime energy infrastructure

Oversized
by design.
Scalable. Combinable.
Integrable.

HACE was designed to deliver maximum capacity factor in all conditions — and to adapt to any ambition: from a single module to gigawatt scale, from combined uses to the most complex ecosystems.

The founding choice

Oversized
by design.

The HACE turbine is sized at 1 MW rated while the system can theoretically produce 9 MW. This is not a constraint — it is a deliberate strategic decision.

Result: the turbine constantly runs at saturation, regardless of sea conditions. In 5 cm of swell or heavy weather. This ratio is what delivers a capacity factor of 50 to 90% — where offshore wind peaks at 30%.

HACE capacity factor—
Offshore wind (reference)25–35%
Solar10–25%

* Estimates from internal models and IRENA data. Final capacity factor depends on site and local swell conditions.

Scalability

Scalable
without friction.

One module. One technology. One manufacturing process — in any shipyard worldwide, with no heavy equipment.

From demonstrator to diesel-dependent island, from coastal project to multi-GW array: the same building block. No technology disruption. No new industrial risk at each step. It is the same machine that multiplies.

Positive externalities

Uses
stack up.

A single HACE installation can simultaneously generate electricity, protect a coastline, power an electrolyzer and secure a port. Each additional use improves overall ROI with no major added cost.

This is the opposite logic of other energies: here, the more you use, the more profitable it gets.

System vision

The building
block of
a more ambitious ecosystem.

HACE could become the energy source of a system that goes beyond simple electricity production. Synergies with complementary players already exist — and the most ambitious architectures are yet to be built.

ZESTAs — Zero-emission maritime transport

Global alliance of 50+ players. HACE as "Absolute Zero" energy supplier for ports and vessels.

Confirmed alliance · 2026

SHZ + H2X — Complete hydrogen chain

20× lighter storage (SHZ) + end-use solutions (H2X). HACE would supply continuous energy at the start of the chain.

Partnership in progress · conditional

Hybrid grids — HACE + wind + solar

HACE's continuous production compensates for the intermittency of other sources. A natural complementarity that could eliminate the need for massive storage.

Identified potential · to develop

Data centers + coastal cooling

Large coastal digital infrastructures could be powered by stable HACE energy while using seawater for cooling.

Emerging use · to be structured
