Generating hydrogen offshore by electrolyzing seawater using renewable power provides limitless energy.
Renewable energy systems often produce more energy than can be consumed at the time. Capturing this surplus energy as hydrogen and storing it for later use to produce electricity will provide stable power supply with zero emissions.
Our offshore integration abilities in production systems and umbilicals, risers, and flowlines provide the means to store hydrogen subsea for later use, and to transport it ashore.

Wind to power and green hydrogen
Deep Purple™ is our solution for integrating renewable energy with hydrogen to form a complete, zero-emission offshore energy system.
It can be configured to a specific energy demand and application, and includes power generation, seawater treatment, electrolysis, hydrogen storage and re-electrification. An energy management system enables its flexible operation – determining when to deliver power directly, when to use it for electrolysis, and when to turn hydrogen stored subsea into electricity.
Our unique subsea storage system provides more capacity than batteries could. Each module holds up to 12 tons of hydrogen, enough to generate 200 megawatt hours – the same as 4,000 electric car batteries.
Deep Purple™ covers two main segments that together represent a total addressable market of 6 gigawatts by 2030:
- Offshore green hydrogen production and subsea infrastructure for coastal applications.
- Off-grid energy systems, delivering renewable and stable power to traditional energy installations and remote islands.
We are in the process of engineering and procuring a small-scale version of Deep Purple™ to demonstrate the system and validate our digital solution.
Deep Purple™ is the key part in integrating hydrogen into Floating Power Plant’s wind-wave floater structure – enabling buffering renewable energy offshore. A potential demonstrator project in the Canary Islands would serve as a scaled validation of key steps in the Deep Purple™ commercialization roadmap and accelerating its technology readiness for commercial projects.
