Hydrogen power is the future of electric cars

The Chinese government is endorsing the implementation of hydrogen vehicles in designated trial regions as it sets up an ecosystem that includes manufacture, storage, transportation and refuelling,

The visualization to make China an electric-vehicle centre revolutionised the global auto industry, reinforcing a move away from the combustion engine. Now, EV expert Wan Gang says get ready for the next game-changing moment.

The world's principal car market is set to embrace hydrogen fuel-cell vehicles the way it did EVs, said Mr Wan, who's been called the father of China's electric-car programmes, in a rare interview in Beijing on June 9. "We should look into establishing a hydrogen society. We need to move further toward fuel cells."

A former Audi executive who went on to become China's science-and-technology minister, Mr Wan persuaded leaders two decades ago to bet on the then-untested technology of vehicle electrification, selling it not only as a way to boost economic growth but also to tackle China's dependence on oil imports and its mounting levels of pollution.

His stratagem - using government subsidizations to bring automakers and drivers on board - made China home to one of every two EVs sold globally currently. And now it's hydrogen's turn, said Mr Wan, 66, a vice-chairman of China's national advisory body for policy making, a role that ranks higher than a minister and gives him a voice in the nation's future planning.

All this means that the government will promise resources to developing such vehicles, he said. While China plans to phase out the long-time subsidy programme for the maturing EV industry next year, government funding for fuel-cell vehicles may stay in place to some extent, he said.

Despite the backing of industry giants such as Toyota Motor Corp. and the benefits of fuel-cell vehicles - they refuel faster and are more suitable for driving long distances than all-electric vehicles - the technology hasn't caught on amid expensive prices.

But China has the force to transform all that should it make hydrogen-powered vehicles a domestic priority - the type of turning point the industry has been waiting decades for.

For Mr Wan - a mechanical engineer trained in Germany - the shift towards hydrogen is a natural step in realising a vision of having electric cars dominate inner-city traffic, while buses and trucks filled with hydrogen tanks roam the nation's highways for long-distance travel.

The adoption of fuel-cell vehicles has been slow in spite of China having an abundant supply of hydrogen, he said. There are only about 1,500 such vehicles in use there today, compared with more than two million purely electric vehicles, he added.

Hydrogen fuel cells have fought to gain traction universally not just because of high costs - one of the key components is platinum - but also the lack of infrastructure and the complexity of storing hydrogen.

Then there's the matter of hydrogen's flammability, as evidenced by the recent fire at a refuelling station in Norway. "We will sort out the factors that have been hindering the development of fuel-cell vehicles," Mr Wan said.

Exertions are ongoing in Japan, which plans to intensify the number of fuel-cell vehicles on its roads to 40,000 by 2020, though Bloomberg NEF estimates sales so far aren't close to that target.

In Europe, Daimler AG's Mercedes-Benz unit rolled out a fuel-cell version of its popular GLC SUV. In the US, the California Fuel Cell Partnership is trying to promote the technology, with limited success.

Buses appear to be particularly ripe for fuel cells, which use a chemical process to convert hydrogen into electricity, emitting only water vapor. China is by far the world leader in using electric buses - accounting for 99 per cent of them worldwide last year, according to researcher BNEF - but they're mostly used in cities for short distances.

"We have a responsibility to reduce emissions," Mr Wan said
