Offshore Wind Power and Renewable Hydrogen Production
There is an emerging consensus in the offshore wind industry that renewable hydrogen will be essential for continued economic success and growth because of the need for large-scale grid-balancing and expansion into new and profitable markets. GTA has pioneered the development and prototype testing of subsea electrolyzers for large scale renewable hydrogen production. High voltage cables and large power transformers are eliminated. GTA’s electrolyzer has been vetted at the National Renewable Energy Laboratory. Please refer to the presentation materials given below. They present feasibility and techno-economic information on this new game-changing technology that is ready for commercialization now.

Designed electrolyzers
have been tested and validated at the National Renewable Energy Laboratory and have an investment grade international patent portfolio available for sale or licensing. We are seeking an enterprising company with business and engineering experience in the offshore energy industry to partner with.
Add Perpetual Revenue & Value
Subsea electrolytic production of renewable hydrogen adds perpetual revenue and value to depleted offshore oil and gas fields.
Subsea Business Opportunities
New business opportunities and markets are presented to the energy, and construction companies engaged in current subsea operations.
Reduce Labor Costs
Subsea electrolytic hydrogen production does not require continuous human presence. Alkaline electrolyzers rarely need servicing.
Autonomous ai operation
low-cost commodity materials
Simple Design
HYDROGEN compression
Deep-water hydrostatic pressure is leveraged for hydrogen production at high pressure. Cool subsea water is leveraged for coolling.
Produced & Stored Safely
Hydrogen is produced and stored in safe locations, away from population centers and protected from inclement weather and EMP events. Delivered to shore by pipeline or to floating production and offloading vessels (FPSOs).
