ASX Green Energy Stocks: $2/kg hydrogen? This company says it could be on the cards by 2025
Australian electrolyser company, Hysata, has demonstrated it can produce green hydrogen from water at 98% cell energy efficiency, enabling a hydrogen production cost well below A$2/kg (US$1.50/kg) by the mid 2020’s.
In a report published in peer-reviewed journal, Nature Communications, the company said its ‘capillary-fed electrolysis cell’ introduces a new concept of water electrolysis that promises increased energy efficiency and lower capital costs, making hydrogen more cost-competitive with fossil fuels.
Producing green hydrogen from water at 98% cell energy efficiency is well above the International Renewable Energy Agency’s (IRENA) 2050 target and significantly better than existing electrolyser technologies, Hysata said.
Green hydrogen is vital for decarbonisation of hard-to-abate sectors like steel, heavy transport, and chemicals.
The Energy Transitions Commission expects demand for green hydrogen to grow to 500-800 million tonnes per annum by 2050 to meet demand in these sectors, creating a new multi-trillion-dollar industry.
Currently however, green hydrogen is too expensive to compete with fossil fuels, due in large part to the low efficiencies of existing electrolysers.
Hysata’s ultra-high efficiency electrolyser will make green hydrogen competitive years earlier than generally assumed, accelerating global decarbonisation, and increasing energy security.
The technology was invented by scientists at the University of Wollongong and is now being commercialised by Hysata, with backing from IP Group and the Clean Energy Finance Corporation (CEFC).
Hysata chief technology officer Gerry Swiegers said the overall design of the Hysata electrolyser system was simpler than existing technologies.
“Electrolysers have been around for 200 years, however the large amounts of renewable electricity required to produce green hydrogen and the overall cost of electrolysers today has prevented large-scale uptake of green hydrogen,” he said.
“This significant step change in hydrogen technology is on track to accelerate the global hydrogen economy and drive down the cost of green hydrogen production in Australia and globally, positioning Australian as a leading manufacturer of electrolysers and producer of green hydrogen.”
ASX vanadium play, Australian Vanadium (ASX:AVL), has been awarded a $49mn Federal manufacturing collaboration grant this week, which will be used in the development of the Australian Vanadium Project, near Meekatharra and Geraldton to create an Australian green fuelled vanadium industry.
AVL shares rose by more than 40% on the news yesterday, with funds also set to support the development of the vanadium redox flow battery market, including vanadium electrolyte and battery project dev elopement for downstream users.
The company said it will collaborate with ATCO to incorporate green hydrogen into the project, which will fuel the processing of vanadium to a >99.9% pure vanadium oxide product, and will work with Bryah Resources (ASX:BYH) to explore the opportunity of processing an economic critical battery mineral resource.
In a separate announcement this morning, AVL said it has also signed a Letter of Intent (LOI) for the supply of its iron titanium co-product, further validating the end user market for the AVL co-product.
The buyer for this LOI is Wingsing International Limited, the commercial arm of Tianzhu Steel – a private owned enterprise (POE) with a mill located in the coastal Hebei province of China and an annual capacity of 5Mtpa steel.
Fluence Corporation (ASX:FLC) secured its first SUBRE MABR plant upgrade contract yesterday, designed to increase wastewater treatment plant capacity from 125,000 people to 167,000 people in Anhui province – an increase of 33% pc while preserving treatment quality.
Instead of enlarging current plants and building new basins, SUBRE towers are submerged in existing chambers, improving effluent quality, lowering the use of chemicals, saving energy and operational costs, and increasing capacity.
SUBRE upgrades wastewater plants using membrane aerated biofilm reactor (MABR) modules.
It is the first project with new customer Anhui Kehuan Environmental Engineering Co.
