Weekly Recap: The divergent paths of Tesla and Fisker

There's no doubt that Tesla is downshifting while Fisker has been grinding its gears. But it wasn't always that way.
In the wake of Tesla's recent success, it's easy to forget that there were once two California electric carmakers with bright futures.

Hydrogen could deliver one fifth of world carbon cuts by 2050, industry says

BONN, Germany — Increasing the use of hydrogen in power, transport, heat and industry could deliver around one fifth of the total carbon emissions cuts needed to limit global warming to safe levels by mid-century, a report by the Hydrogen Council said on Monday. To encourage industries to use hydrogen, Toyota and Air Liquide helped set up the Hydrogen Council, a global lobby launched in January this year. Its 27 members include automakers Audi, BMW, Daimler, Honda and Hyundai, and energy firms such as Shell and Total. The council said using hydrogen for transport, energy generation, energy storage, industry, heat and power could cut annual carbon emissions by 6 billion tonnes by 2050. "This would ... contribute roughly 20 percent of the additional abatement required to limit global warming to two degrees Celsius," the council said in a report released on the sidelines of a U.N. climate conference in Bonn. To achieve a two-degree limit this century agreed by governments in Paris in 2015, the world must reduce energy-related carbon emissions by 60 percent by 2050. The report said one in 12 cars sold in California, Germany and Japan were expected to be powered by hydrogen by 2030. By 2050, hydrogen could power 400 million cars, 15 million to 20 million trucks, around 5 million buses, a quarter of passenger ships and a fifth of non-electrified train tracks, as well as some airplanes and freight ships. Achieving this shift in transport and other sectors would require investment of $280 billion by 2030, with about $110 billion to fund hydrogen output, $80 billion for storage, transport and distribution, and $70 billion to develop products. Fuel cell vehicles combine hydrogen and oxygen to produce electricity to power an electric motor, producing water as a byproduct. However, making hydrogen from fossil fuels, a common route, also produces some greenhouse gas emissions. So far the take-up of hydrogen vehicles is tiny and industry experts say their wider use is years away, with high purchase prices and a lack of refueling stations the major barriers. But some firms, such as miner Anglo American and carmaker Toyota, are pushing for fuel cell cars to play a role even with the rise of battery-powered electric vehicles (EVs). Woong-chul Yang, vice chairman of automotive research and development at Hyundai said EVs and hydrogen fuel cell cars were needed because EVs were better for city driving and fuel cell vehicles better for longer journeys.

Audi A4 TDI plans scrapped for the US

It comes as no great surprise, but Audi of America president Scott Keogh told Automotive News that the automaker has ditched plans to offer the 2.0-liter TDI-powered A4 here in the US. Despite what you may be thinking, Keogh claims the decision isn't based on the ongoing talks between parent company Volkswagen and US regulators regarding the diesel emissions scandal. (Currently, Audi and Volkswagen are awaiting EPA certification for their diesel engines in the US.) The reason, he says, is that the demand for diesel sedans is low here, particularly when compared to the company's lineup of crossovers. "The marketplace speaks, we listen to the marketplace, and the marketplace told us, 'Go with SUVs,'" says Keogh, presumably in his usual straightforward, assuring manner. That's not to say, though, that one doesn't have an effect on the other. We've already seen that the scandal has had an impact on sales. Now, in a country where many were already under the assumption that diesel engines were dirty and noisy, it's no revelation that automakers are less than enthusiastic about expanding their grease-burning offerings. While the news is a bit of a bummer for those of us who have long hoped for more widespread diesel options here in the States (and for whom the whole Dieselgate debacle is downright depressing), there's still plenty to look forward to in terms of greener, cleaner Audis. At the A3 E-Tron event late last year, Keogh was bullish on EVs, promising that it was just the first step in a "substantial commitment." Audi's plan is, in Keogh's words, to "start with the plugs, come in with the full BEVs and then keep rolling from there." He repeated these assurances at the LA Auto show, saying that he expects 20 to 25 percent of Audi's sales to be plug-in vehicles by 2025. Plus, despite the whole diesel thing (which, to be fair, affects far fewer Audi cars than Volkswagens), Audi has been killing it lately. February sales marked a streak of 62 consecutive months of record sales in the US. For an automaker that is repeatedly saying that it believes the future is in electrification, this bodes well for us. Related Video:
