Revolutionising Green Hydrogen: Seawater Electrolysis Without Desalination
Building resilience and sustainability into hydrogen production at scale.
About Us
By re-thinking electrolysis, Hychor, a spin-out from the University of Aberdeen, has engineered a novel method of producing hydrogen from seawater instead of freshwater which current technologies rely on.
The Freshwater Problem in Green Hydrogen Production
By 2050, green hydrogen may account for up to 35% of the UK’s energy system. However, producing hydrogen through electrolysis is freshwater-intensive, withdrawing up to 32.2 litres of freshwater per kilogram of hydrogen. At scale, this presents a major bottleneck. Seawater is a limitless alternative, but current methods require energy-intensive desalination, which drives up costs and produces polluting brine.

Globally, by 2050, green hydrogen production could withdraw over 11.5 Giga Tons of freshwater—more than three times the UK's annual domestic water use.

Hychor’s solution
Seawater Electrolysis Without Desalination
Hychor’s technology eliminates the need for desalination, reducing both capital and operational costs. Unlike traditional methods, our electrolysers can safely return seawater to the ocean without removing salts or additives, avoiding the generation of corrosive by-products or polluting brine.
This allows hydrogen production without the environmental impact of brine and at the same energy input as existing systems
Why Choose Hychor
Cost-Effective, Sustainable, Scalable
Eliminate Desalination and Reduce Costs
Hychor removes the need for desalination, simplifying plant design and reducing both operational and capital costs. This solution scales to meet the needs of large energy providers and industries, while supporting a sustainable future by not tapping into freshwater resources.
Maximise Renewable Energy Efficiency
When combined with renewable energy, such as wind, excess electricity can be converted into green hydrogen—avoiding costly grid constraint payments and ensuring energy isn’t wasted
Zero Pollution, High Efficiency
Our process is simple: hydrogen and oxygen are produced without by-products, ensuring zero pollution and high efficiency.
