$潍柴动力(SZ000338)$ 总部位于澳大利亚的Hysata的毛细管电解电池能够以98%的电池能效从水中生产绿色氢气，据该公司称，这远远高于IRENA的2050年目标。
到2020年代中期，我们的技术将使氢气产量低于每公斤1.50美元，比一般预期更早地达到澳大利亚和全球的成本目标。这对于绿色氢的商业可行性和难以减少的行业去碳化至关重要。
Australian electrolyser manufacturer Hysata claims its electrolyser technology could enable hydrogen production costs to fall below US$1.5/kg by the mid-2020s.
The research, which was published in the peer-reviewed scientific journal Nature Communications, confirmed Hysata’s ‘capillary-fed electrolysis cell’ can deliver a 95% system efficiency, almost 20% higher than modern alkaline electrolysers which produce the best system efficiency so far.
Paul Barrett, CEO of Hysata said the technology will allow green hydrogen to “outcompete fossil fuel-derived hydrogen” with production cost to fall below US$1.5/kg by the mid-2020s putting Australia as a “leading manufacturer” and exporter of electrolysers.
“This is critical to making green hydrogen commercially viable and decarbonising hard-to-abate sectors,” said Barrett.
Barrett’s prediction is five years earlier than IRENA’s or research firm IHS Markit’s prediction costs for green hydrogen being able to outcompete blue (or grey) hydrogen in all major markets, with IRENA predicting a cost of US$2.46/kg by 2030 for Australia using solar as the energy source.
Barrett added the company is on its way to commercialise the technology and reach gigawatt scale hydrogen production by 2025.
A report about hydrogen production costs from the UK government’s Department for Business, Energy & Industrial Strategy (BEIS), suggested conversion efficiencies would increase to 82-86% for alkaline, PEM and solid oxide electrolysers by 2050.
Gerry Swiegers, chief technology officer at Hysata, said: “Hysata’s overall electrolyser system has been designed for ease of manufacturing, scaling and installation, delivering 95 percent overall system efficiency, equivalent to 41.5 kWh/kg, compared to 75 percent or less for existing electrolyser technologies.”
Swiegers added the technology stands to reduce both capital and operational costs for hydrogen producers to make green hydrogen.
The technology was first created by scientists at the University of Wollongong and will be commercialised by Hysata, backed by IP Group and the Clean Energy Finance Corporation (CEFC).
With green hydrogen projects increasing in the past few years, many initiatives have been announced in the past two years to ramp up green hydrogen production.
During COP26 last year, the UN-supported Green Hydrogen Catapult (GHC) committed to bring 45GW of green hydrogen electrolyser capacity to a final investment decision by 2026 and commissioning by 2027.
An European initiative, the HyDeal Ambition initiative aims to achieve 67GW of electrolysis capacity by 2030 and deliver green hydrogen across Europe at €1.5/kg (US$1.82) before 2030.
