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.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

2014 Mercedes S-Class priced lower from $92,900*

The massively overhauled 2014 Mercedes-Benz S-Class will start at $92,900, not including a $925 destination fee, when it arrives at US dealers in October. That's a 2.8-percent drop over the 2013 S-Class, although Mercedes is fast to point out that a drop in price doesn't equate with a drop in equipment for the executive sedan.
Besides an extra 20 horsepower from the 4.6-liter, biturbocharged V8, the S550 sports a standard panoramic sunroof, keyless start, a rear-view camera and LED headlights, taillights and interior lights. Adding the German manufacturer's 4Matic all-wheel-drive system bumps the S550's price up to $95,900.
If the S550 doesn't quite cut the mustard, you can wait until November, at which point Mercedes will quite happily sell you the new S63 AMG 4Matic for $139,500. Power is also up on the S63, from a max of 563 ponies with an AMG Performance Package to 577 horsepower as standard on the 2014 model.
