Hysata – Electrolyser Breaks Efficiency Records, Enabling World-Beating Green Hydrogen Cost
The title of this post, is the same as that of this article on Hydrogen Central.
These three paragraphs explain what Hysata have achieved.
Hysata – electrolyser breaks efficiency records, enabling world-beating green hydrogen cost.
Hysata’s world-leading hydrogen electrolyser technology has been recognised on the global stage with ground-breaking research published in top tier peer-reviewed scientific journal Nature Communications.
The research confirms Hysata’s ‘capillary-fed electrolysis cell’ can produce green hydrogen from water at 98% cell energy efficiency, well above International Renewable Energy Agency’s (IRENA) 2050 target and significantly better than existing electrolyser technologies, enabling a hydrogen production cost well below A$2/kg (US$1.50/kg).
Note.
- Hysata are an Australian company.
- The research and its results have have met the gold standard of pier review in a respected journal.
Their efficiency levels would appear to be breathtaking.
I have some more information and a couple of thoughts.
The Technology
This article on New Atlas is entitled Record-Breaking Hydrogen Electrolyzer Claims 95% Efficiency, gives a full overview of the technology.
It does appear that Hysata have shown tremendous attention to detail to raise the efficiency.
The Efficiency
In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, I said the following.
Ryze Hydrogen are building the Herne Bay electrolyser.
- It will consume 23 MW of solar and wind power.
- It will produce ten tonnes of hydrogen per day.
The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.
55.2 MWh/tonne is 55.2 kWh/kg.
Hysata are claiming on their web site, that their electrolysers have 95% efficiency, which is 41.5 kWh/kg.
- A megawatt of electricity at Herne Bay will produce 18.1 Kg of hydrogen.
- A megawatt of electricity in a Hysata electrolyser will produce 24.1 Kg of hydrogen.
That is 33 % more.
Gelion Claims Zinc-Bromine Gel Batteries Will Replace Lithium-Ion
The title of this post, is the same as that as this article on RideApart.
These are the first two paragraphs.
Battery technologies are evolving at a rapid pace—and for good reasons. With the automotive world moving toward electrification, companies need to find solutions for producing electric vehicles on a massive scale. While lithium-ion battery technology rules the roost today, that isn’t stopping firms from developing the next big leap forward.
From solid-state power units to structural batteries to sci-fi-worthy quantum batteries, there’s no shortage of ideas and concepts. However, the Australian company Gelion Technologies believes it found a more affordable and durable approach with its zinc-bromine gel battery. Unlike lithium-ion units, the material found in Gelion’s design isn’t rare, expensive, or potentially flammable.
It’s yet another development coming out of Australia.
Fortescue Future Industries And Airbus Join Forces To Help Decarbonise Aviation
The title of this post, is the same as that of this press release from Fortescue Future Industries.
These are the first two paragraphs.
Global green hydrogen company Fortescue Future Industries (FFI) and Airbus, a world leader in aeronautics, have joined forces to create a working alliance to help enable the aviation industry to decarbonise through zero-emissions green hydrogen.
Today’s announcement reflects FFI’s and Airbus’ shared ambition to leverage their respective expertise to support the entry-into-service of a green hydrogen-based aircraft by 2035. Green hydrogen, unlike other forms of hydrogen, is made from water using 100 per cent renewable electricity.
I think this is a smart move by Airbus.
It could be argued that hydrogen trucks, buses, cars, vans and other road vehicles have not taken off at a great rate due to the lack of hydrogen filling stations.
Hydrogen airliners travelling on typical routes will probably need refuelling at both ends of the route and possibly several times per day, so hydrogen refuelling would be an important part of any deal Airbus signs with an airline.
Fortescue Future Industries seem to be in prime position to be the first global hydrogen company, so they must be the ideal hydrogen fuelling partner.
I don’t think anybody predicted, when Airbus published the possible designs of their concepts for hydrogen-powered aircraft in September 2020, that I wrote about in ZEROe – Towards The World’s First Zero-Emission Commercial Aircraft, that an Australian company would be likely to provide the hydrogen fuel for these aircraft.
Earth Friendly Concrete
I was alerted to this product by this article on New Civil Engineer, which is entitled Keltbray Saves Carbon And Money With Earth Friendly Concrete On East London Job.
The article gave enough clues to find the Earth Friendly Concrete home page.
This is the introduction on the page.
We want to have a positive impact on the environment and supply our customers with an excellent product, that is why we created Earth Friendly Concrete ® by Wagners. It is a concrete that uses no ordinary Portland cement, instead using a geopolymer binder system made from the chemical activation of two industrial waste by-products – blast furnace slag (waste from iron production) and fly ash (waste from coal fired power generation). Our product has ZERO Portland cement and it has a much lower embodied energy compared to ordinary concrete, saving 250kg of CO2 for every cubic metre poured. Importantly, the engineering and construction properties of this environmentally friendly concrete is, in some areas, better than normal concrete. EFC has some significant performance advantages over normal Portland cement concrete, including improved durability, lower shrinkage, earlier strength gain, higher flexural tensile strength and increased fire resistance.
On this page, which is entitled About EFC, this said about the products Environmental Excellence.
EFC is a new class of concrete that contains NO ordinary Cement. Globally, the production of 1 tonne of Portland Cement produces 1 tonne of CO₂ emissions and is responsible for 5 to 8% of manmade greenhouse gas emissions. Instead of cement, EFC has a geopolymer binder that is made from the chemical activation of two recycled industrial wastes, flyash and slag. This recycled binder reduces the CO₂ emissions associated with Portland cement by 80 to 90%.
Every m3 of 40 MPa EFC saves 220kg CO₂ emissions.
Wagners, the company behind the development, are based in Queensland. Australia.
So it’s a case of Well Done The Aussies!
They have appointed Capital Concrete, to deliver Earth Friendly Concrete in the London area.
Conclusion
Does High Speed Two and other large projects that will need large amounts of concrete, know about this development?
What is Mineral Carbonation And How Could It Transform The Building Industry?
The title of this post, is the same as that of this article on AZO CleanTech.
This is the introductory paragraph.
Natural carbonates have been prime building materials for centuries, but synthetic carbonates are a modern, robust building material, created via mineral carbonation.
The article is a must-read introduction to this fascinating Australian technology, which could be very important in combating climate change.
There is also an explanatory video, which is worth a watch.
Fortescue’s Forrest Says German Hydrogen Deal Is Just The Start
The title of this post, is the same as that of this article on Reuters.
This is the opening paragraph.
Australian miner Fortescue Metals’ (FMG.AX) newly-announced deal to supply green hydrogen to Germany is just the start as the rest of the world will catch up with Europe’s lead, Fortescue’s chairman told a Berlin industry conference on Monday.
I very much agree with Andrew “Twiggy” Forrest, as if countries are serious about commitments to fight global warming, there will be a big rush for hydrogen, so that countries can decarbonise their chemical, steel and other industries.
Some countries like Australia, Canada, Denmark, Norway, Spain, Sweden, The Netherlands, the UK and the US will be fine, but others will struggle.
Germany seems to be taking action by buying up supplies from everywhere they can.
Wabtec’s 100% Electric Locomotive Trickle Suddenly Becomes International Flood
The title of this post, is the same as that of this article on Clean Technica.
This is the introductory paragraph.
Whelp, that was fast. The locomotive manufacturer Wabtec lit up the Intertubes last November when it debuted the new FLXdrive 100% electric locomotive in Pennsylvania, but that was just the beginning. The company has nailed down two clients in Australia for its carbon-free choo-choo while also locking in a spot on the new Europe’s Rail Joint Undertaking, which aims to green up railway systems throughout Europe.
It certainly has been quick.
Usually, only in times of war, do things go that fast.
But you could argue that climate change is as big a threat to the world than China, Iran, North Korea or Russia.
BHP Joins The Party On Electric Rail
The title of this post, is the same as that of this article on Australian Mining.
This is the introductory paragraph.
BHP will add four battery-electric locomotives to its Western Australian rail network, becoming the fourth major miner to improve rail decarbonisation efforts in Australia since mid-December.
These are some details of the locomotives.
- Two are from Progress Rail and two are from Wabtec.
- The locomotives have 14.5 MWh batteries.
- The locomotives will be delivered by 2023.
BHP will also investigate the use of regenerative braking using the topography of the rail route.
With four companies going electric, it does seem that Australian mining, is very much driving the move to battery-electric heavy-haul freight.
Considering, that Wabtec only formally launched the FLXdrive concept in Pittsburgh in September last year, which I wrote about in FLXdrive ‘Electrifies’ Pittsburgh, that would appear to have been good going.
Goldman Sachs Invests $250 million In Hydrostor To Advance Compressed Air Energy Storage Projects
The title of this post, is the same as that of this article on pv Magazine.
This is the introductory paragraph.
The investment is planned to support development and construction of Hydrostor’s 1.1GW, 8.7GWh of Advanced Compressed Air Energy Storage projects that are well underway in California and Australia, and help expand Hydrostor’s project development pipeline globally.
It certainly seems that the big beasts of finance are starting to back innovative energy storage.
Green Ships Ahoy Along Vital Corridors
The title of this post, is the same as that of this article on 7 News Australia.
These are the first two paragraphs.
Australia’s biggest miners are preparing for a day of reckoning.
Shipping accounts for two to three per cent of global greenhouse gas emissions so manufacturers and retailers are no longer just considering what appears in national targets.
The article then goes on to explain how the big mining companies are cutting their emissions.
This paragraph illustrates how important mining and shipping is to Australia.
Resources and energy earnings passed $300 billion for the first time in 2020-21 and will surge towards $400 billion in 2021-22, according to December figures.
Hence the big need for ships fuelled by lower carbon fuels.
