Are hydrogen cars the solution to the expected lithium shortage?September 29, 2022
As fuel cell vehicles have much smaller batteries, they could prevent a deficit in the rare metal.
Lithium is a critical part of the batteries needed in electric vehicles, and many zero-emission vehicle experts are hoping consumers will choose hydrogen cars to help prevent what some are calling a rapidly approaching shortage.
Lithium deficits could be inevitable within the coming decade if electric vehicle trends continue.
It’s more than clear that electric vehicles are far more popular than hydrogen cars in the current passenger vehicle market. While both do require a rechargeable battery, the unit in fuel cell vehicles is notably smaller and therefore requires considerably less lithium. Many experts in green transportation are hoping that larger and luxury vehicles will take a closer look at H2 to help prevent a large deficit in lithium.
The Advanced Propulsion Centre (APC) in the United Kingdom – which is UK government-backed – addressed the issue in its quarterly industry demand report, which it recently published. The organization works to boost the automotive industry’s net-zero transition.
In a previous report from the APC, the group had already identified a risk of a lithium shortage due to the rapid EV adoption increase. At that time, the APC stated that a lithium supply deficit would force automakers to reduce their EV production levels and have to develop and adopt next-generation batteries such as fuel cells in hydrogen cars.
In the APC’s most recent report, it has placed the spotlight back on hydrogen cars and lithium shortages.
The report warned that automakers and suppliers will need to prepare themselves to “mitigate” against supply shortages. It went on to recommend that they “diversify powertrain choice in the short to medium term” before they are forced to do so due to a lack of materials.
Some automakers have already had a focus on hydrogen cars and have been releasing their H2-powered models to a limited extent. Toyota has certainly become the most recognized of the automakers focusing on H2-powered passenger cars. The 2022 Toyota Mirai has all the outward appearance and performance of a luxury sedan.
Hyundai is another large automaker that has invested heavily in H2. Its 2022 NEXO is a crossover SUV which has a look and range similar to its conventional internal combustion engine models. Both Hyundai and Toyota have had small productions of their H2 vehicles when compared to the rollouts of electric vehicles from other automakers.
Battery tech best suits the lightest vehicles, with hydrogen cars working well in larger models.
According to the APC report, hydrogen cars will work well in large and luxury models. Approximately half of those vehicles would work well as zero-emission alternatives with H2 powertrains, said the report. It is small and light vehicles that are best suited to battery electric technology as they require smaller batteries and therefore less lithium.
As luxury models already have relatively small production runs, they would suit fuel cell rollouts well, said the report. It indicated that about half of all SUVs, four-wheel drive cars and delivery vans could switch away from batteries.
The report predicted that bout 6 percent of newly UK-manufactured cars and vans could be powered by hydrogen fuel cells by 2030. Comparatively, it expects that the same will be said for about 1 percent of vehicles in the rest of the world. Though there are a growing number of hydrogen cars currently driving on UK roads, it is mainly bus companies that have been adoption H2 as a zero-emission fuel.
If the trend toward the use of hydrogen cars doesn’t pick up, or if another alternative to conventional battery electric vehicles doesn’t roll out instead, global lithium supplies will rapidly fail to meet demand.
Sodium batteries are the solution to the lithium limitation for the industry. Also they are the economical and ecological option to the use of Lithium batteries.
How come Hydrogen fuel news is not addressing it as the road to green energies?
Surely car and van manufacturers will take the JCB route of using the hydrogen in an internal combustion engine and leave out the fuel cell component. Then only a small battery would be needed.
Hydrogen fuel cell cars will quickly be taken up when a reliable network of H2 supply points is available
At present most are in southern England although Orkney has H2 supplies produced locally, population only 20000!
Come on Government……..
The predicted shortage of lithium must favour arguments in favour of Hydrogen cell vehicles v electric vehicles which are only an interim solution for carbon free motor vehicles !
If so WHEN can we expect to see :
1.the mass production of Hydrogen vehicles (particularly cars and vans) at reasonable prices in the UK and
2. easily available supplies of hydrogen fuel ⛽️ at all UK filling stations to supply the above vehicles ideally well before 2030 – this must surely be in the longer term interests of the oil majors ? Would it be possible to supply their H2 pumps from on-site electrolysis units powered by green energy & water?
Perhaps Sir Keir Starmer’s proposed state owned Great British Energy firm could help by emphasising the vital importance of *H2 alongside
*wind *solar *tidal & *nuclear power ?
It is hardly surprising that there are few hydrogen powered cars in the UK, when there are almost no hydrogen filling stations compared to the Continent. Past Governments have created a problem by not planning the infrastructure of hydrogen filling stations, and more EVs are placing a strain on the ability of the national grid to support so many charging points, especially those for high speed charging. The lack of hydrogen is also forcing some bus companies to go for battery powered buses rather than hydrogen.
Before we can even consider H2FC vehicles we need to ensure that ALL commercial electricity generation is obliged to use their excess capacity to electrolyse water so that a constant trickle of H2 is produced, to store that capacity.
