One kilogram of hydrogen has 39.4 kWh of energy, but current commercial electrolyzers typically cost 52.5 kWh to create. Australian company Hysata says its new capillary-fed electrolyzer cell cuts those energy costs to 41.5 kWh, breaks down efficiency records and is cheaper to install and run. The company promises green hydrogen at US $ 1.50 per kilogram in just a few years.

Efficiency is one of the biggest blows against hydrogen as we move towards the future of clean energy. It can store more energy per weight or volume than batteries and it supports fast refuelling, which is useful in applications where batteries do not have the energy density to compete. But since batteries are the most efficient way to store and release energy, hydrogen seems to throw energy at every step: electrolysis, storage and transport, converting it back into electricity through the fuel cell … heck, it leaks slowly. Metal tank.
what it says on the tin,
If Hysata’s new electrolyzer technology does what it says on the tin, the efficiency of the electrolysis stage will be better utilised with precious pure energy. And by lowering CAPEX and OPEX costs for operators, by generating more hydrogen from a specific energy supply, this tool can lower the cost of green H2, perhaps to the point where it becomes competitive with dirty hydrogen or fossil fuels.
How does it work?
So how does it work? According to Hysata, it’s about blisters. Blisters in the electrolyte fluid are not conductive, and they can cling to the electrodes and hide them from contact with the fluids they need to touch to do their job. This is surely a problem as electrolyzers convert water into H2 and O2 gases.
According to Hysata, early electrolyzers had both electrodes immersed in the electrolyte, forming bubbles around them. In the 70s, zero-gap electrolysis brought the anode and cathode directly into contact with the separator membrane, increasing the efficiency by allowing only bubbles to form on one side of each electrode. More recently, polymer electrolyte membrane technology has allowed the cathode side to run without electrolyte.

Hysata’s characteristics of the evolution of electrolyzers, which led to the company’s exceptionally effective new design.
ThevHysata’s capillary-fed electrolyzer cell takes things to the next and possibly final level. The reservoir at the bottom of the cell keeps the electrolyte away from contact with both the anode and the cathode, which is pulled through a porous, hydrophilic, inter-electrode separator using a capillary action. The electrolyte has direct contact with the electrodes, but only on one side, and both hydrogen and oxygen gases are produced directly, without any bubbling.
Resistance is further reduced by the fact that the water does not pull to the side of the electrode releasing the gas, so the two do not overlap and when the water is electrolyzed by the separator, the capillary action draws. More from the reservoir to replace it.
In a peer-reviewed paper posted in Nature Communications, the Hysata group claims that its capillary-motion electrolyzer mobileular reveals ninety eight percent record-breaking efficiency, higher than “state-of-the-art [presumably asymmetric polymer”. Electrolyte membrane] business water electrolyte. “It reveals eighty three percent mobileular efficiency. Gas crossover is very low – this is crucial, because at the right temperatures and concentrations, the hydrogen-air mixture is explosive.
The company says the technology will reduce costs outside the cell. No need for fluid circulation, gas-liquid separator tanks, piping, pumps and fittings. This gear can be air-cooled or radiantly self-cooled, cutting high capital and operating costs, and if the gravity-limited peak height of the capillary action proves to be a limiting factor, you can just pop in, says Hiasata. Run over the reservoir tank and down the separator instead of the electrolyte.
All these factors help to reduce the “plant balance” energy consumption outside the electrolyzer cell, creating an even bigger gap between this technology and others when looking at overall system efficiency.
“Hysata’s ordinary electrolyzer machine is designed for ease of manufacturing, scaling and installation, turning in ninety five percentage ordinary machine efficiency, identical to 41.five kWh / kg, seventy five percentage or much less in comparison to current electrolyzer technologies,” stated business enterprise Swiegers Gerry. Press release. “For hydrogen producers, this will significantly reduce the investment and operating costs for producing green hydrogen.”
Swingers calls this device “a whole new class of electrolyzer that is reminiscent of the move from an internal combustion engine to electric motors.”
Hysata CEO Paul Barrett says the business enterprise plans to commercialise the era and have “a gigawatt-ability hydrogen manufacturing ability through 2025,” at which factor they consider that US $ 1.50 consistent with kilogram of hydrogen. Plans are underway to build a pilot electrolyzer production plant, and the company is hiring “dozen” in 2022 as part of the process.
Hydrogen production is expected to skyrocket in the coming years as Green H2 finds its place in the tough sectors of the new green energy economy. So there is definitely a gold rush, and producers expect a squeeze on electrolyzer production to get their facilities up and running. In such cases, a cheap, super-efficient electrolyzer will certainly find itself in great demand, so Hysata may have a gigantic product on its hands and an opportunity to make an impactful contribution to the combat towards weather change.
Of course, there is a long race between published paper and massive commercial success, but with the potential Ulta that Hysata is claiming, this is clearly a company to look out for.
Hysata is an Australian electrolyzer company that is developing an entirely new type of electrolyzer, which has the world’s most efficient electrolysis cell and a simplified balance of the plant.
Green hydrogen generates high costs and, therefore, the most efficient electrolyzer delivers low cost hydrogen.
Hysata’s founding team includes experts in the electrolyzer industry, with deep expertise in the design and scale-up of novel electrolyzers. On top of that we are developing a world-class engineering, manufacturing and commercial team with a footprint across multiple continents.
With the support of major global investors, Hysata is moving rapidly toward production on the multi-gigawatt scale needed to address climate change.
