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 E-Tron Quattro TDI Quick Spin

The operating word is quiet. This refers both to the sound inside the cabin of the upcoming Audi Q7 E-Tron Quattro TDI – even with the diesel engine running – and the company's public statements about its plan for this powertrain in the United States. Basically, while Europe is getting the diesel plug-in sometime next spring (a bit of a delay), all we know for sure right now is that the US will be getting the Q7 E-Tron, probably in 2018, and it will have either a 3.0-liter turbodiesel or 2.0-liter turbocharged gas engine. You may now place your bets as to which one you think the public (or, more likely, CARB) will go for. We're guessing 2.0T. Despite not knowing if we'll ever see this E-Tron TDI on our side of the Atlantic, we recently spent an enjoyable morning tooling around the hills outside Madrid, Spain. As we said, this beast is seriously quiet, and impressively so. Driving Notes The Q7 is a big vehicle, but with powertrain that combines electric motors and diesel thrust, there's a ton of low-end torque. The official 0-62 time is 6.0 seconds, which is basically the same as the 6.1 seconds of the non-PHEV Q7. The Q7 E-Tron is about 500 pounds heavier than the already-4,700-pound Q7, but because of its trick powertrain, never felt sluggish in the hills of Spain. This Q7 E-Tron is a parallel hybrid, with the 3.0-liter TDI diesel engine and the 94-kW disc motor both able to drive the wheels. Overall, they provide 373 horsepower and 516 pound-feet of torque. Despite the parallel system, the not-quite-powerful-enough electric motor doesn't provide the complete electric drive experience that EV fans might be looking for. For example, the Q7 E-Tron has a top speed of 139.8 mph, but that's only in hybrid mode. In EV mode, its top speed is just 78 mph. Audi's Virtual Cockpit display, first seen in the TT, remains an ideal way to give you a wealth of information in an easy-to-see format. It's just as slick in the Q7, where you can toggle the size of the gauges and then pick what you want the screen to focus on, whether that's speed limits, infotainment information, powertrain usage, speed, or navigation.

How Audi will make roads friendlier to autonomous cars

Today, Audi announced some of the new projects it will be implementing on Germany's Digital Motorway Test Bed, which comprises a few sections of highway on which the government and industry can test autonomous and connected tech. Among Audi's projects is one specifically aimed at making roads easier for autonomous cars to navigate. Audi is looking to make the road and other objects more visible. The company has been researching materials that could make guardrails and road markers reflect radar waves more readily, and Audi will install test versions soon. The goal here is to help make these objects easier for the autonomous vehicle's sensors to see in inclement weather, and at greater distances in good weather. The company will also test additional road markings that will be easier to see for onboard cameras and will help the car place itself on the road. Audi will also try out new vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) technology that will be able to alert cars to speed limits, traffic conditions, ice patches and possibly allow for driving patterns such as platooning. This will be a significant step above the traffic light communication system Audi has released in select areas. The company will also be working on very detailed mapping of the area. Audi claims it will be accurate down to the centimeter. From what we've seen at MCity, the world as it stands presents all kinds of difficulties for autonomous vehicles, from worn-out signs to rough pavement. So any advances that make it easier for autonomous cars to see and communicate should help bring such vehicles to reality much sooner.
