Designed to power ports, islands, and clean hydrogen at scale.
<2g CO₂/kWh
(compared to 25g for offshore wind power)
<2€/kg H₂ green
Truly competitive green hydrogen.
100% recyclable steel
No concrete foundation
Consistent energy production
Designed for grid connection and storage
HACE harnesses wave energy via a unique Oscillating Water Column (OWC) system.
🌊
Waves push water up into the columns, compressing air in an upper chamber.
💨
The compressed air powers a one-way turbine, isolated from seawater to prevent corrosion.
⚡
Power is delivered to the grid or converted into green hydrogen.
🧱
The entire system is modular, concrete-free, and made of recyclable steel.
HACE is committed to coexisting with all marine stakeholders
Globally patented – Field-tested since 2018 – Proven at sea in 2023
High-impact solutions for a faster energy transition
The HACE system enables strategic, high-impact uses—particularly where other renewables struggle. With continuous output and <2g CO₂/kWh, it’s a core asset for:
