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.

Mercedes-AMG planning hybrid hypercar?

It used to be that, a few overlapping two-door models aside, Mercedes-Benz and Porsche didn't really compete with one another. That's how the two ended up collaborating on projects like the Mercedes 500 E that put it on the performance sedan map without fear of stepping on each other's toes. But Porsche has grown considerably since then, challenging its Stuttgart neighbor with four-door sedans and crossovers, as well as sports coupes and convertibles. Little wonder, then, that Mercedes has hit back at Porsche with the AMG GT, and there will be many more versions to follow in 911 style. But that may not be the final salvo the Silver Star marque launches at Zuffenhausen. According to the latest bit of speculation and deduction from our friends at Motor Trend, Mercedes-AMG may be planning a hybrid hypercar of its own to take on the Porsche 918 Spyder – not to mention the McLaren P1 and LaFerrari. Solid information is sparse at this point, but after speaking to AMG chief Tobias Moers, MT speculates that the new flagship will likely be mid-engined, with a boosted version of the company's 4.0-liter twin-turbo V8 kicking out between 650 and 700 horsepower, working with a pair of electric motors at the front to deliver tenacious through-the-road all-wheel traction and a combined output in the thousand-horsepower range. There is the possibility, though, that Mercedes could go after the latest hybrid hypercars with a flagship version of its just-launched AMG GT, packing a similar powertrain setup as the ultimate evolution of the breed. Other GT versions will likely soon include a GT3 racing model, a Black Series version and a roadster – following a similar path taken not only by the 911, but also by Benz's previous halo supercars like the SLR McLaren and SLS AMG.
