It isn’t solely the enterprising folks serving to themselves to the catalytic converters in parked vehicles who search to recycle invaluable platinum. Bosch needs to get well platinum the authorized approach moderately than reducing it out from beneath different folks’s vehicles.
The objective is to recycle the platinum that goes into hydrogen gas cells when the cells attain the tip of their helpful lives. It may be reused in new gas cells or be used for different functions corresponding to new catalytic converters. Bosch estimates that it might probably get well 95 p.c of the platinum that goes into its gas cells.
Q&A With Bosch President on the Migration to EVs
In line with derivatives market CME Group, Inc., recycled platinum at the moment accounts for about 25 p.c of the trade’s provide, with 80 p.c of that complete coming from automotive catalysts. A lot of the relaxation comes from recycled jewellery.
To get well the platinum, Bosch has inked a cope with Cologne-based mobility startup Hylane, which offers for the repurchase of fuel-cell stacks by Bosch after their helpful lives within the hydrogen vans Hylane leases.
The deal ensures Bosch an choice to repurchase stacks, which can be recycled by a third-party firm. Hylene’s profit is that Bosch will use the recovered platinum in gas cells destined to be used in Hylane’s vans.
“We’re proud to have reached this progressive mannequin settlement with Bosch that offers it the choice to repurchase retired fuel-cell stacks,” mentioned Hylane managing director, Sara Schiffer. “To realize a sustainable transformation in mobility, it’s necessary that we think about not solely automobile use on the roads however all the automobile lifecycle as effectively.”

Because it does in catalytic converters, platinum acts as a catalyst within the gas cell. On this case, it accelerates the response of hydrogen and oxygen moderately than oxidizing unburned hydrocarbons.
The dear steel is $938 an oz on the time of this text’s writing. For comparability, gold is $1,932 and palladium, which can be utilized in catalytic converters, is $1,250. Silver is a discount at $23. World demand for platinum will develop by 20 p.c by 2040, in accordance with a 2021 research by the German Mineral Assets Company, so recycling will assist maintain a lid on worth will increase.
Moreover, recycling platinum will assist Bosch cap the carbon footprint of its gas cell manufacturing. In that course of, platinum accounts for 80 p.c of the carbon emissions, Bosch says.
“By recycling, we are able to make the stacks extra economical and on the similar time scale back the carbon emissions related to platinum mining,” mentioned Thomas Pauer, the president of the Bosch Powertrain Options division. “We’re already laying the groundwork for recovering uncommon uncooked supplies like platinum.”
“Our estimates counsel that by 2030 on the newest, considerable numbers of gas cells will want recycling,” Pauer continued. This seven-year span from now compares to a median 13-year lifespan for catalytic converters earlier than they’re recycled, in accordance with the CME Group.
After they do, it should each lower your expenses and scale back the CO2 emissions related to the manufacturing of future gas cells. “By recycling, we are able to make the stacks extra economical and on the similar time scale back the carbon emissions related to platinum mining,” Pauer mentioned.

Bosch factors out that as a part of its Bosch eXchange program, the corporate’s Automotive Aftermarket division has been reconditioning components corresponding to used starter and alternator items for many years, which is an much more environment friendly type of recycling.
