Doug Vining There's a fundamental problem with this headline

Natural gas, while cleaner than oil, is still a 'fossil' fuel. India has large gas reserves, and also the largest coal reserves in the world. They are already looking at coal-to-fuel processes from Sasol to provide energy for their growing economy. So I don't see how they can have a 'no more fossil fuel' strategy - maybe 'no more imported oil' would be more accurate?

We are in violent agreement - but the 20-year strategy pursued by India and others in this scenario specifically takes them beyond LPG and others towards a Hydrogen Economy - beyond fossil fuels - both for public and private transportation and power generation. LPG and other fossil-based fuels are just an interim step in the process to reduce emissions.

Doug Vining China's economy reaching environmental limits

14 April 2007
BEIJING (AFP) - China's booming economy is being increasingly constrained by shortages of energy and natural resources as well as environmental concerns -- forcing the nation to seek a more efficient growth model.

According to high-ranking officials in Beijing, there is simply not enough fuel around on the planet to sustain a Chinese boom using the same energy-intensive recipe that made the western nations rich.

China would need 4.5 billion tonnes of oil annually if it consumed energy like the United States, according to Xu Dingming, the vice head of an energy task force at the National Development and Reform Commission, the country's economic planner.

But the annual global oil supply is just four billion tonnes, including 1.6 billion tonnes in commercial circulation, Xinhua news agency quoted Xu as saying earlier this month.

Officials are aware of the looming pressures, but they also say it will not be easy to change an economic formula that has resulted in a 25-year boom with little attention to efficiency or the environment.

"Over the past two years we've seen a change, as the government has acknowledged environmental degradation is resulting in social instability," Yang Ailun, Greenpeace China's expert on climate change, told AFP.

Jack Nel Enough resources?

Just a comment, haven’t had a chance to look at the underlying research yet.

Does the world have enough hydrogen resources to pull this off? Thought that comes to mind is that we will probably be facing water shortages by 2015.

Brett Dawson A few concerns

My biggest problem with H2 is that it is only an energy carrier. You still need a primary energy source to generate H2 and this MB doesn't answer that question, which is probably the most important. The carbon footprint of the primary fuel is one key issue. There are energy losses with each conversion process and so even though fuel cells have high efficiencies (currently in the lab) it doesn't take the full energy chain into account. High pressure H2 storage alone isn't sufficient for vehicles - the "tank distance" is too small.

CNG is still a fossil fuel and still has GHG problems, even though it is better than diesel (because of the lower Carbon/hydrogen ratio). The % improvement depends on the conversion technology used, efficiency and optimization. Energy used for compression (to turn NG into CNG) is often not taken into account. Natural gas fields reach production peaks and fissle out much faster than oil fields. Maintaining sustainable supplies is a massive challenge.
LPG cannot realistically replace diesel because a barrel of oil has diesel & LPG fractions in it. To make LPG you will still get a large diesel fraction. If you only use LPG then you need to export all the diesel (large market to find & expensive). SOFC's are not suitable for transport because they generate a lot of heat (high T FC).
It's very difficult to address all these issues in one MB.

Doug Vining RE: China builds a green dream machine

An interesting read. I wonder if the Chinese usage model will export very well - I can't see the average western owner unplug the battery and take it upstairs to be charged. On the other hand, with that kind of pricing, it will need several orders of magnitude of production expansion before they need to export anything at all!

Doug Vining China to reduce coal dependence

China's coal consumption is likely to drop to 63 percent of total energy consumption by 2015, down from 70 percent last year, said an official with the National Energy Administration. Non-fossil fuels will provide 11 percent of China's energy needs in 2015 and 15 percent in 2020, said Jiang Bing, head of the development and planning department of the NEA.

The future of energy is a deeply fascinating space! There will be new winners,m and some big losers - mainly slow and cumbersome incumbents, locked into fossil fuels.
