Lower Cost, Scalable
and Higher Efficiency
Electrolysis
Hadean has developed a low-cost tubular Solid Oxide Electrolyser (tSOE) with higher efficiency than incumbent technologies like PEM and Alkaline electrolysis. Our mission is to accelerate industrial decarbonisation.
Lower cost
No use of platinum group metals
Scalable
Efficient
Up to 30% less electricity consumption compared to PEM and Alkaline technologies
TECHNOLOGY
SOLID OXIDE ELECTROLYSIS
Solid oxide electrolysis (SOE) is the most efficient method of electrolysis when integrated with waste industrial heat.
SOE converts steam into hydrogen and oxygen in an electrochemical reaction, using a ceramic electrolyte. It can utilise industrial waste heat to increase the efficiency of the cell, making SOE up to 30% more energy efficient than PEM and Alkaline technologies.
Hadean’s tubular solid oxide cell structure reduces cost and reduces system complexity.
SOLID OXIDE ELECTROLYSIS
APPLICATIONS
With the ability to generate clean hydrogen as a versatile fuel, SOE holds tremendous potential for a wide range of applications.
Whether it’s powering fuel cells, supporting industrial processes, or propelling transportation, the hydrogen produced through SOE can help drive the decarbonisation of our energy systems, contributing to a greener and more sustainable future.
SOLID OXIDE ELECTROLYSIS
INDUSTRIES
Green hydrogen produced through electrolysis is a renewable resource that can be readily integrated into current industrial processes.
It is particularly important in hard-to-abate industries, including:

NGV Earth and Hadean Energy Join Forces to Build Breakthrough eSAF Pilot Plant
Melbourne, Victoria – Jul. 2025: In a groundbreaking move toward greener skies, NGV Earth and Hadean Energy have joined forces to build a first-of-a-kind integrated pilot facility for producing synthetic sustainable aviation fuel (eSAF). This pioneering collaboration blends NGV Earth’s cutting-edge catalytic fuel synthesis process with Hadean Energy’s revolutionary tubular Solid Oxide Electrolyser (tSOE) technology, heralding a major step forward in aviation sustainability.
Hadean electrolyser pilot demonstrates efficiency and durability at Bluescope Steel Plant
Nov. 2024: CSIRO, Australia’s national science agency, has successfully trialled its game-changing hydrogen production technology at BlueScope’s Port Kembla Steelworks in New South Wales, demonstrating affordable and renewable hydrogen can be generated at scale to help decarbonise heavy industry.
CSIRO’s tubular solid oxide electrolysis (SOE) technology has clocked 1000 hours of successful operation in the trial with BlueScope Steel which commenced in October 2024.
Unlike conventional hydrogen electrolysers, which rely heavily on electricity to split water into hydrogen and oxygen, CSIRO’s advanced SOE technology uses both waste heat (for example, steam from the steelworks) and electricity to produce hydrogen with greater efficiency.
