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 Q7 plug-in hybrid spied, Porsche powertrain possible

It's no secret that a new Audi Q7 is on the way. The replacement for the aging, three-row luxury CUV has already been spotted once, in December of 2013. Now, though, we have images of the second-generation model lapping Germany's Nürburgring Nordschleife, and it just happens to be showing a feature we reported on at the end of July - a plug-in-hybrid powertrain.
Given away by its high-voltage stickers on the window and a spare door to hide the charger - note how both the driver and passenger sides sport an access point - our spies snapped a series of photos, and put forth the compelling idea that the new Q7 would use the PHV system from the Porsche Cayenne S E-Hybrid.
If that's the case, that should mean at least 320 horsepower from a 3.0-liter, supercharged V6, while an electric motor chips in a further 95 ponies for a total system output of 416 hp.

Spy video shows Audi RS4 Avant twin-turbo V6 lapping the Nurburgring

Nurburgring testing season is in full swing, and Audi took some of its newest upcoming models for a spin. That means our first listen to Ingolstadt's new, turbocharged RS engine under the hood of the RS4. Based off the updated A4, the new RS4 Avant is a return to the performance variant's roots. The original RS4 (and early versions of the S4) used twin-turbo V6 power, although more recent models stuffed the beloved 4.2-liter V8 under the hood. The turbo engine in the new model is also rumored to find its way into the back of the R8 supercar. We don't know horsepower figures yet, but with 450 horsepower as the benchmark from the last RS4 we expect big numbers from the six-cylinder. The new engine might be just as powerful as the old V8, but as you'll see in the video, it's missing the phenomenal growl that the 4.2-liter made as it revved to the sky. This new car is quiet, especially compared to the ear-tingling five-cylinder note of the TT RS testing alongside the wagon. A quiet performance car is fine if you like stealth, but with its flared wheel arches, oval exhausts, and big wheels, the RS4 is a car that's anything but subtle.
