NREL scientists advance solar thermochemical hydrogen (STCH) production
Perovskite materials may hold the potential to play an important role in a process to produce hydrogen in a renewable manner, according to an analysis from scientists at the National Renewable Energy Laboratory (NREL). Hydrogen has emerged as an important carrier to store energy generated by ...
I know they claim its green H2 but this is Australia. All H2 produced will be made from syngas derived from coal. Aus has a lot of coal and they want to use it all. Greenwashing.
Aviation H2 selects liquid ammonia as carbon-free fuel of choice
Following a three-month feasibility study, Aviation H2—an Australian-owned company seeking to achieve net-zero emissions in the aerospace sector through green hydrogen—has selected the use of liquid ammonia to turbofan combustion as the best route to carbon-free flight and will soon start modif...
That 89.2% is at 4.8V . 95.1% at4.7V for 160 cycles is a bit better.
Sodium is my great hope.
Researchers in China develop high-voltage-resistant electrolyte for ultrahigh voltage Li metal batteries
Researchers in China have developed a high-voltage-resistant (HV electrolyte) for use in ultrahigh-voltage lithium metal batteries. As reported in an open-access paper in the RSC journal Energy & Environmental Science, Li||LiNi0.8Co0.1Mn0.1O2 (NCM811) cells, which can work in a wide operating te...
This is not good news.
Tesla is targeting 3000 GWH by 2030 alone. About half for grid storage.
There is huge demand and constrained supply=inflated prices.
Benchmark: Li-ion battery pipeline could exceed 6 TWh by end of decade
Global lithium ion production capacity could reach over 6,000 GWh (6 TWh) by the end of the decade based on current plans, as companies accelerate gigafactory construction in Europe and the US, according to Benchmark Mineral Intelligence. Total lithium-ion capacity existing or being built has...
These seem somewhat off. When Nissan introduced the Leaf in 2010 I remember Nissan saying they were paying< $400 /Kwh at the cell level.
The figure from the comentariat was $375/Kwh at the cell level.
Now these were LMO cells ,not a good choice but LFPs would be the same price.
BloombergNEF annual battery price survey finds prices fell 6% from 2020 to 2021
Lithium-ion battery pack prices, which were above $1,200 per kilowatt-hour in 2010, have fallen 89% in real terms to $132/kWh in 2021, according to a new report from BloombergNEF (BNEF). (All prices are in real 2021 $, unless stated as nominal.) This marks a 6% drop from $140/kWh in 2020. Contin...
This should not be called green hydrogen. If you are using electricity from the NSW grid which is majority coal produced it is not green.
Typical for the sleazy NSW government.
Jemena and Coregas partner on green hydrogen for New South Wales transport industry
Australian energy infrastructure company Jemena and gas supply company Coregas are partnering to advance the use of green hydrogen for the transport industry in New South Wales. Under a new agreement, Jemena will produce and supply green hydrogen from its Western Sydney plant for use by tr...
Fine as far as it goes. Really should include LFP chemistry.
Australia is now importing Tesla model 3 with with LFP and Canada also soon.
BYD is also entering the market with LFP and are claiming 140wh/kg at the pack level.
Argonne study compares life cycle emissions of battery-grade lithium carbonate and lithium hydroxide from brines and ores
Researchers at Argonne National Laboratory have conducted life cycle analyses (LCAs) for battery-grade lithium carbonate (Li2CO3) and lithium hydroxide monohydrate (LiOH•H2O) produced from Chilean brines (Salar de Atacama) and Australian spodumene ores. An open-access paper on the study is publi...
G ood to see something other than coal ,sugar and methane coming out of Qld.
160-170 wh/kg would be very good for LFP. Right now the Tesla model3 SR coming into Aust. has LFP cells and BYD is shipping several models all with LFP "blade" cells.
It all comes down to price and with a cathode of aluminium and chlorine it could be cheap.
One thing not mentioned is that it does not overheat so no pack cooling.
Seems like a nobrainer for hybrids or even F1.
UQ, GMG graphene-enhanced aluminum-ion batteries show very high power density, long life

They are going to struggle.
Mercedes-Benz starts production of battery systems for the new EQS and expands EV expertise
Mercedes-Benz has started producing high-performance batteries for its all-electric luxury EQS at its Stuttgart-Hedelfingen plant, as part of the Untertürkheim location in Germany, ahead of the sedan’s world premiere on 15 April 2021. The EQS marks the start of a new generation of high-performa...
From this article it is stated that they are removing one ton of CO2 for each ton of H2.
However wikipedia states that for producing H2 by steam reforming of LNG ,which is what is happening here (because it is cheapest), between 9 and12 tons of CO2 is produced for each ton of H2 (depending on quality of feedstock).
Nothing green going on here.
It would simpler ,cheaper and cleaner to take the CH4 ,compress it and run it through an ICE. Say like the NissanEpower unit.
SK Group to invest $16.4B to create hydrogen production-distribution-consumption ecosystem by 2025
Korea-based SK Group will invest about 18 trillion won (US$16.4 billion) over the next five years to create a domestic hydrogen ecosystem—production, distribution, and consumption—through creation of domestic hydrogen infrastructure and also through partnerships with global companies. In the fi...
You have to understand we do it differently here in Oz.
The biggest and best lithium mine in the world. the Talison mine in WA has been sold to a Chinese(state) company who see no advantage in value adding in Oz,
This is customary here. The iron ore, coal, gas,aluminium etc are all majority owned by "offshore" entities.
We have a prime minister who has a lump of coal as a pet rock.
The government has changed the rules so that gas producers can use funds set aside for alternate energy.
The government cannot agree that global warming is caused by humans.
Roskill expects only 3.2% reduction in shipping emissions of spodumene concentrate by 2030; order of magnitude below IMO ambition
Shipping emissions form a significant part of the commodity supply chain’s carbon footprint, particularly for those commodities reliant on the mass transport of low-grade ores and concentrates. Roskill has analyzed the trend in carbon intensity of shipping using spodumene concentrate as an examp...

Thank you for your well crafted comment.
The 70% efficiency for 150degreeC FC is stated as a target.
Ive seen cell startups "targeting " 400wh/kg for years now.
I truly hope both come true but I reckon the batteries might get there first.

First luv your work Roger.
But this time youve strayed into fanciful territory.
Claiming that FCs are 3X as efficient as turboprops is a bit of a stretch. We know that PEMs are ~50% efficient at best and that energy must then be translated to motive power via an emotor , a loss of another 10% so 45%.
The present F1 engines are claiming >50%. Toyotas 4 cylinder engine claims to have efficiency >40%. Big diesels are also getting ~45%.
But I do agree that PEMFCs would be more efficient than turboprops.
The real problem is liquid hydrogen. I get flashbacks of the Challenger disaster.
Handling the stuff at -250 to-260 degrees C, in a commercial setting, nup.
If you really must have FCs ,then go for SOFCs with a liquid fuel.
Not really green but you could call it biofuel.

I agree the engineers are not morons.
They are doing what they are being paid to do.
I am sure they can probably build a hydrogen fueled plane. The question is why.
To provide 700bar hydrogen at the small airports this plane is aimed for is problematic.
Hydrogen will always be expensive(unless made from fossil fuels).
With the incremental increase in energy density and the drop in price of batteries hydrogen may have a niche position but cannot compete in the market place without financial help or the use of fossil fuels.
As sd relates in a lower comment there is a 9 seater with a range of 420 miles running on batteries and they planning to fly the hydrogen Malibu 300 miles.

Claiming 300 to 500 mile range. Could do that with batteries a lot cheaper and simpler. Boris might have been sold a pup here.

Hey mahonj . These are still high temp (>750 degrees C) ,so not suitable for LDVs . Could perhaps work for long distance trucks or work boats. There is a lot of cheap sugar around here. But as you allude ,best to stay away from Au and Pt.

Thanks for the reply EP. Yes a printer is a complex and expensive machine but so is a press and dies(and the heated steel).
The NUMMI plant is said to have a floor area of 5.5m sq ft enough for 50,000 car sized beds. Now you wont use that many , but you might have a few thousand of various sizes(making wheels/doors ,whatever).
The "printers" might be the ones using light to catalyze the composite, faster and a fair finish.
They would be cheaper when made in the thousands(perhaps many thousands).
And you save a couple of tons of co2 for every ton of steel not used.

I cant agree EP. The footprint of the printer is not much bigger than the object being made so there are many. Very little human intervention is needed. Modifications and new designs are quickly and cheaply implemented.
A great way of using some of the CNTs being electrolytic produced from CO2 ala prof. Licht.
Strong light and wont rust.Lovely.
