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.

2017 Audi A4 First Drive [w/video]

Internally, Audi refers to the A4 lineage with a B designation. Why the discrepancy? The model legacy traces back to the 1972 Audi 80, and the A4 name wasn't adopted until 1996 for the North American market. So the fifth-generation A4 is code-named B9. There is no confusion about what this car means to Audi. In 19 years, the brand has sold more than 12 million A4s around the world, which puts this new generation on the A-list when it comes to brand importance. If you squint, the new car looks like a facelifted version of the last-generation facelift unveiled in 2013. We get the same impression of the new A4 as we do with the third-generation Audi TT: it hasn't been comprehensively reconceived, it's been comprehensively re-detailed. But with a move to the updated VW group platform known as MLB Evo, 90 percent of the components on this car are new. On the outside, those changes are reflected through deeper sculpting on a body that's about the same height as before but 0.5-inches wider, one-inch longer, and with a wheelbase stretched 0.7 inches. The tweaked grille separates reworked Bi-Xenon headlights, which are standard across the lineup now – halogens go bye-bye. LED headlights are optional, as are the matrix units in other markets. Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. Above those lights is a version of a clamshell hood – its shutline forms the front third of the pronounced shoulder line along the sedan's flanks. Audi designed a new hinge that keeps the hood lined up properly over the life of a car because small misalignments show more easily on the vertical seams. In back there are updated taillights, a standard rearview camera, and a trunk opening that's an even one meter across. In the press presentations, any conversation quickly turns to weight loss and aerodynamic efficiency. The only curb weight we have from Audi so far is for the base sedan, empty and without a driver, with the 1.4 TFSI engine that we don't get, coming in at 2,910 pounds. The current US-spec A4 is listed at 3,583 pounds, and Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. About 35 pounds of that comes from the chassis, with new forged aluminum links on the suspension, fixed-caliper, four-piston brakes up front, and wheels that are never heavier than 26 pounds. The rest of the weight loss comes from the body, mostly through greater use of aluminum.

Audi promises production laser headlights

Audi is showing off new laser headlight technology this week at the 2014 Consumer Electronics Show on its Audi Sport Quattro Laserlight Concept, and most intriguingly, the automaker has plans to use the long-range lighting on production vehicles. Audi CEO Rupert Stadler tells Automotive News that this type of headlights will be used on a future production vehicle, although he did not specify any timeframe.
On the concept vehicle, the headlights employ LED low beams, while the high beams use the laserlight technology. Audi says that these lights are not only very small ("a few microns in diameter") they are also able to light the road for almost a third of a mile (1,640 feet), with three times the brightness of an LED highbeam, yet with pinpoint control. These lights have already been confirmed for use in motorsports on the 2014 Audi R18 e-tron Quattro LMP1 racecar, and the tech will eventually trickle down to road-going cars.
In addition to how long this trickle down will take, it's doubtful we'll see these lights in the US anytime soon. Audi is still working with the US Department of Transportation for approval of its LED Matrix Beam headlights, which are already sold in other markets, and the negotiations appear to be taking quite a bit of time. Automotive News also notes that the laser headlights earmarked as options on the 2015 BMW i8 will not be offered in the US, either.
