(FOR) CUMMINS BACKING H2 & ELECTRIC

Cummins is developing battery-electric and hydrogen fuel cell electric power trains for trucks, commercial vehicles, rail and potentially aircraft. CUMMINS INC.

Cummins Inc., a century-old maker of truck engines powered by diesel and other fossil fuels, may not seem like the most likely attendee at the UN Climate Conference COP26 in Glasgow, Scotland, but CEO Tom Linebarger was there last week telling industrial partners and customers the company is working to help them shift to low- and no-carbon vehicles powered by batteries and hydrogen.

As battery-electric passenger models gain market share in the U.S., Europe and China, attention is shifting to electrifying larger, dirtier commercial vehicles including semi-trucks, construction and mining vehicles, as well as trains, ships and aircraft. Currently, no single type of electric power train can easily scale to handle light and heavy-duty vehicle categories, so it’s necessary to use both, Linebarger tells Forbes.

“If you’re flogging one thing and you trash the other, it's not a good plan for meeting the challenge of climate change,” he said from Glasgow. “Climate change is the existential crisis of our time. It’s just not a good idea to argue about whether batteries are better than fuel cells.”

Tesla CEO Elon Musk, whose company has become synonymous with electric cars, is among the most vocal critics of using hydrogen as a transportation fuel, citing its inefficiency relative to batteries and the high cost of the fuel cell stacks that make electric power from hydrogen and oxygen. Yet makers of trucks and commercial vehicles that need to travel long distances aren’t convinced that multi-ton, lithium-ion battery packs that need relatively long recharge times are the best option. (Notably, Musk also doesn’t launch his SpaceX rockets with batteries, but instead a blend of kerosene and liquid oxygen that spew climate-warming black carbon, or soot.)

Shifting away from carbon-based fuels was a key topic for negotiators at COP26 and appeared to have made a historic breakthrough with a first-draft agreement calling for the phasing out of fossil fuel subsidies. But a second draft appeared to soften the wording as major oil and gas producers fight to save subsidies. Forbes - link - Alan Ohnsman - link - more like this - link

(H2V) HYDROGEN ICE

Hydrogen-fuelled internal combustion engines, or ICEs for short, will add “significant momentum” to the deployment of zero-emission commercial vehicles and heavy-duty trucks and could be the earliest adopters of such technology, Cummins told H2 View.

Mobility is a sector benefitting considerably from hydrogen, with the clean energy carrier sporting longer distances and zero emissions; it is often seen as a perfect complement to battery electric vehicles.

Perhaps the most exciting technology bubbling in the mobility sector is hydrogen-fuelled internal combustion engines, with interest around the subject skyrocketing in recent months.

And for US industrial firm Cummins, this has been no exception. In July, Cummins revealed it had begun testing of a new internal combustion engine that can use green hydrogen fuel.

Amy Davis, Vice-President and President of New Power at Cummins, confirmed to H2 View Cummins has successfully established initial proof-of-concept and is now accelerating the programme ahead -  link - George Heynes - link - more like this - link
