Another big car company gives up on hydrogen

engadget.com Unknown 2025-07-21 12:30:11

Stellantis, the automotive giant behind Chrysler, Citroen, Fiat, Jeep and Peugeot, is pulling out of hydrogen. The company said it’s killing its fuel cell development program in the face of “limited availability of hydrogen refueling infrastructure, high capital requirements and the need for stronger consumer purchasing incentives.” To put that another way, it’s realized hydrogen EVs are facing the same set of challenges it’s not been able to overcome in the last two or three decades. It’s a st

Feds tell automakers to forget about paying fuel economy fines

Automakers selling cars in the United States now have even less incentive to care about fuel economy. As Ars has noted before, the current administration and its Republican allies in Congress have been working hard to undermine federal regulations meant to make our vehicle fleet more efficient. Some measures have been aimed at decreasing adoption of electric vehicles—for example the IRS clean vehicle tax credit will be eliminated at the end of September. Others have targeted federal fuel econom

Stellantis abandons hydrogen fuel cell development

arstechnica.com Unknown 2025-07-23 16:51:59

To paraphrase Mean Girls, "stop trying to make hydrogen happen." For some years now, detractors of battery electric vehicles have held up hydrogen as a clean fuel panacea. That sometimes refers to hydrogen combustion engines, but more often, it's hydrogen fuel cell electric vehicles, or FCEVs. Both promise motoring with only water emitted from the vehicles' exhausts. It's just that hydrogen actually kinda sucks as a fuel, and automaker Stellantis announced today that it is ending the developmen

Nuclear Waste Reprocessing Gains Momentum in the U.S.

news.ycombinator.com Julia Tilton 2025-08-03 05:28:58

The United States’ 90,000-ton stockpile of radioactive nuclear waste has long been a liability, but researchers are increasingly eyeing it as a resource. New techniques in transforming spent fuel, new nuclear fuel cycle directives from the Trump administration, and the doling out of a Biden-era $40 million research program together aim to repurpose nuclear waste on a commercial scale. In a suite of executive orders announced on May 23, U.S. President Donald Trump directed the U.S. Department of

China jumps ahead in the race to achieve a new kind of reuse in space

arstechnica.com Unknown 2025-08-07 01:18:02

Two Chinese satellites have rendezvoused with one another more than 20,000 miles above the Earth in what analysts believe is the first high-altitude attempt at orbital refueling. China's Shijian-21 and Shijian-25 satellites, known as SJ-21 and SJ-25 for short, likely docked together in geosynchronous orbit some time last week. This is the conclusion of multiple civilian satellite trackers using open source imagery showing the two satellites coming together, then becoming indistinguishable as a

GOP budget bill poised to crush renewable energy in the US

arstechnica.com Unknown 2025-08-17 20:34:15

Far from the front lines of the climate crisis, 100 men and women in air-conditioned offices, 61 of them millionaires, are making decisions that could increase United States carbon dioxide emissions, and the warming of the climate they are driving, for decades to come. In the latest political wrangle over energy and climate policy, a group of Republican senators over the weekend added provisions to the U.S. federal budget bill that, as currently written, would end clean energy tax credits at th

Lamborghini Revuelto review: perfect harmony

theverge.com Peter Nelson 2025-08-20 05:00:00

With the dawning of a new era of hybridization in the automotive industry, more and more manufacturers are integrating electric propulsion into their lineups. Mild-hybrid systems are well-established, and more beneficial plug-in hybrid systems keep getting better and better. Even Lamborghini’s participating in the latest wave of hybridization, which might come as a surprise to some. That’s because this Italian company’s outlandish supercars have never been regarded as thrifty, or ever trying to

Biofuels Policy, a Mainstay of American Agriculture, a Failure for the Climate

news.ycombinator.com Georgina Gustin 2025-09-12 05:02:22

The American Midwest is home to some of the richest, most productive farmland in the world, enabling its transformation into a vast corn- and soy-producing machine—a conversion spurred largely by decades-long policies that support the production of biofuels. But a new report takes a big swing at the ethanol orthodoxy of American agriculture, criticizing the industry for causing economic and social imbalances across rural communities and saying that the expansion of biofuels will increase greenh
