Revolutionising Hydrogen Production with Seawater Electrolysis
As global demand for green hydrogen continues to rise, hydrogen producers are searching for sustainable, cost-effective solutions that can scale to meet future needs. Hychor has developed a cutting-edge seawater electrolysis technology that eliminates the need for desalination, reducing both operational and capital costs for hydrogen producers.
Why Seawater Electrolysis?
At the predicted scale of the hydrogen economy, tapping into domestic water supplies may be unsustainable or act as a bottleneck for a rapidly expanding industry. On-shore freshwater sources, such as rivers, are prone to fluctuations due to changing weather conditions which may impact production. Seawater is a limitless, stable water source which does not rely on co-locating to a domestic supply or freshwater source. Current traditional hydrogen production relies on freshwater for electrolysis, which requires costly desalination when seawater is used. This not only increases expenses but also produces harmful brine waste and other chemical residues, further impacting the environment. Hychor’s seawater electrolysis technology removes these barriers, offering hydrogen producers a sustainable solution that:
Eliminates the need for desalination, saving on capital and operational costs.
Produces no harmful by-products like brine, ensuring environmentally friendly operations.
Scales to meet demand, making it a long-term solution for large-scale hydrogen production.

Key Benefits for Hydrogen Producers
Reduce Costs and Complexity
By eliminating the need for desalination, our technology significantly reduces the cost and complexity of hydrogen production. With fewer infrastructure requirements and lower energy use, hydrogen producers can optimise their operations and cut costs.
Environmentally Sustainable
Seawater electrolysis removes brine production from desalination, making it a more sustainable solution compared to traditional methods. As well as this our technology doesnt produce chemical by-poducts. Using seawater, hydrogen producers can reduce their reliance on freshwater resources, contributing to global sustainability goals.
Seamless Integration with Renewables
Hychor’s technology can integrate with renewable energy sources, such as wind or solar power. Any excess renewable energy can be efficiently converted into green hydrogen, helping producers avoid grid constraint payments and make the most of renewable resources.
Building-in System Resilience
Hychor’s technology derisks issues of water sourcing from unstable freshwater supplies, ensuring access to a constant output of hydrogen. By eliminating desalination and brine production, our technology also addresses environmental concerns and potential future policies surrounding brine output.
Who Can Benefit from Hychor's Technology
Large-Scale Hydrogen Producers
Cut costs and simplify operation of plant by adopting seawater electrolysis without the need for desalination.
Renewable Energy Providers
Couple renewable electricity with hydrogen production to maximise energy production and eliminate constraint payments.
How Hychor’s Technology Works
Hychor’s innovative approach to seawater electrolysis technology allows hydrogen production without desalination. Traditionally, seawater electrolysis has been challenging due to corrosive by-products formed from seawater’s salts, namely chloride, but Hychor’s novel approach overcomes this, allowing safe, efficient hydrogen production while returning seawater safely to the ocean.
Our novel system’s approach take an alternative reaction pathway than traditional electrolysis, allowing us to by-pass corrosive chlorine production but with the same predicted energy input.
How does Hychor’s system compare to traditional desalination-based methods in terms of cost?
Because we take a system’s approach rather than a material one, we can utilise current commercially available materials, expecting a similar or improved cost, all while removing the costs of desalination. A net improvement.
Can Hychor’s system integrate with our existing hydrogen production setup?
Our electrolysers strive to conform to industrial electrolyser standards, ensuring easy integration into plant.
What are the long-term environmental benefits?
Brine, which is typically twice as concentrated and denser than seawater, may significantly increase the local salinity of the environment and negatively impact the ecology. Our technology on the other-hand only increases the concentration by <1%, only taking the hydrogen and oxygen we need
Is maintenance more complex compared to traditional electrolysis?
Membrane fouling is an issue in all electrolysers, particularly those using seawater, but we are working towards solving this issue by optimising effluent pre-treatment, separator selection, and utilising our unique system for in-situ maintenance.
