A world-first research has confirmed the potential for LNG and its infrastructure to behave as an accelerator for the rising world hydrogen financial system.
Key factors:
- The paper demonstrates, for the primary time, the viability and business potential of a whole hydrogen provide chain from Australia to Japan based mostly on the transport of LNG.
- The idea is predicated on a hydrogen provide chain entailing LNG export to Japan the place it’s used for blue hydrogen manufacturing and by-product carbon dioxide (CO2) is liquefied and repatriated to Australia for sequestration or utilisation.
- Throughout the provide chain, numerous hydrogen manufacturing applied sciences have been assessed, together with steam methane reforming (SMR), autothermal reforming (ATR) and pure gasoline pyrolysis (NGP).
- SMR with carbon seize and storage (CCS) resulted within the lowest complete hydrogen provide value of US$19.00/GJ (US$2.30/kgH2) which meets the 2030 Japanese hydrogen value goal of US$25.00/GJ (US$3.00/kgH2). This expertise additionally obtained the bottom CO2 emission depth (EI) of 38 kg CO2/GJ (4.5 kg CO2/kgH2).
- The evaluation signifies this provide chain can act to considerably scale back CO2 emissions and meet focused hydrogen provide prices.
Researchers from the Future Power Exports Cooperative Analysis Centre (FEnEx CRC) not too long ago made the discovering in a peer-reviewed research revealed within the Worldwide Journal of Hydrogen Power.
Talking on the Australian Hydrogen Analysis Convention held in Canberra, FEnEx CRC CEO, Professor Eric Might, stated the research has demonstrated {that a} viable and cost-effective hydrogen export enterprise from Australia to Japan may very well be achieved quickly by harnessing the experience and infrastructure of the established LNG sector.
Professor Might stated LNG is a supply of significant power all through Asia and the world; nonetheless, it’s a lot much less recognised for its potential to speed up the event of business scale hydrogen.
“Proper now, the world is working to succeed in internet zero by 2050 and there’s no doubt that hydrogen can play a essential position as we search for low carbon sources of power,” he stated.
“The fee-effective manufacturing and supply of ‘inexperienced’ hydrogen developed from renewable sources is an final aim however, at current, we now have plenty of vital technical and price obstacles that must be solved earlier than that is viable.
“Our researchers present that utilizing LNG and current applied sciences can shortly set up a provide chain to ship what is commonly termed ‘blue’ hydrogen to Japan from Australia, inside the fee goal set by the Authorities of Japan (GOJ) and at a CO2 emission depth effectively beneath proposed targets.”
Professor Might stated the paper explored how hydrogen may very well be produced from shipped LNG to Japan at a price of US$2.30/kg which met the 2030 GOJ goal of US$3.00/kg. The paper, Techno-economic and Environmental Evaluation of LNG Export for Hydrogen Production, additionally outlined that by utilizing current carbon, seize and storage (CCS) applied sciences, LNG-produced hydrogen may meet emission depth targets for hydrogen.
“What we will see is {that a} full hydrogen provide chain entailing LNG exports to Japan, its conversion into hydrogen, after which liquefying and repatriating by-product CO2 to Australia for sequestration or utilisation is financially and technically achievable,” Professor Might stated.
Professor Might stated a significant good thing about growing an LNG-based hydrogen export provide chain meant that the world may begin to break down the obstacles for hydrogen adoption and in addition permit researchers and corporations to ‘study from doing’.
“If we look forward to the expertise and the infrastructure wanted to develop and use solely inexperienced hydrogen, we sluggish our progress in direction of reaching internet zero,” he stated.
“What we’d like is extra hydrogen within the market – blue or inexperienced – in order that it, as a cleaner type of power, will be extra more and more adopted and permit governments and the general public all over the world to achieve confidence in it as a sustainable power supply for the longer term.”
Professor Might stated he hoped the paper would stimulate dialogue throughout governments and business on utilizing LNG as a viable hydrogen export choice till different hydrogen provide chain choices (similar to liquid hydrogen or ammonia) develop into aggressive.
He additionally believed the paper ought to speed up dialogue about how CCS ought to be thought of as an important device within the power transition.
Professor Might stated the research was the results of an infinite quantity of analysis collaboration by scientists and engineers on the College of Western Australia and Curtin College group, which included: Saif Al Ghafri, Caitlin Revell, Mauricio Di Lorenzo, Gongkui Xiao, Craig E. Buckley, and Michael Johns.
Professor Buckley at Curtin College leads the FEnEx CRC’s Hydrogen Exports and Worth Chains Analysis Program, whereas the paper’s corresponding creator, Professor Michael Johns on the College of Western Australia, is the Director of Analysis for the FEnEx CRC.
