Carbon capture storage and China
by Ray Block
Energy Information Administration, an agency of the US government, says that world coal consumption is expected to increase by 49 per cent from 2006 to 2030.
Over the same 24 year period, coal’s share of world energy consumption will rise marginally from 27 to 28 per cent. In the electric power sector, coal’s share of world energy consumption moves from 42 per cent in 2006 to 40 per cent in 2o2o, and then increases again to 42 per cent by 2030.
An even larger growth pattern in energy related CO2 emissions is projected by the International Energy Agency, which forecasts a 57 per cent rise by 2030.
Hopefully by that stage, carbon capture, transport, and storage technology will have reached peak success levels, such that CO2 emissions will become negligible.
This is not a fairy tale, at least not intentionally, because a large number of countries are willing to spend big to prove the technology’s success. The Global Carbon Capture and Storage Institute headquartered in Australia has as foundation members 23 national governments and 100 major companies and organisations.
All these participants have a stake in either coal production, coal generated power, enhanced oil recovery, CO2 pipelines and tankers, all reliant on successful outcomes in carbon capture and storage.
China, now the world’s largest carbon polluter consumes more than 1.1 billion metric tons of coal per year, and the US which has swapped places with China to be the second largest polluter consumes about half the Chinese total. These two countries consume over 70 per cent of world coal consumption.
Australia’s largest scientific and industrial research organisation, CSIRO, has a joint venture with the Huaneng Group for a post carbon combustion pilot facility in China involving carbon capture and storage. Huaneng has a majority stake in Huaneng Power International, China’s largest electricity generating company with a capacity of 39,203 MW.
Post carbon combustion may not eliminate all the CO2 escaping into the atmosphere. But it is the only one of the three CCS technologies, which can be retrofitted to existing power plants.
From remarks made to the Shanghai Daily, you get the strong feeling that the Chinese at this stage haven’t any intention to spend much on carbon capture and storage to reduce carbon emissions. So that the Chinese-Australian initiative may not be much more than going through the motions.
Huaneng’s joint venture with CSIRO in carbon capture and storage started with a power plant in Beijing. The intention has been that at the end of 2009, the research would move to a second carbon capture project in a power plant in Shanghai.
The Shanghai Daily(June 1 2009) quoted Jiang Minhua, director general of Huaneng’s science and technology department as saying CCS ”is extremely expensive” He said that high costs are holding back further progress.
Jiang Minhua said that by 2050, capturing CO2 before it is released into the atmosphere could provide 15 per cent of the carbon reduction required to reduce greenhouse gas.
Minhua said that “carbon capture costs around 200 yuan (US$29.31) per ton using current technology. And actually handling it, processing it, so it can be used industrially, will cost another 150 yuan ($21.98) per ton.”
The $51.29 in Huaneng CCS costs can’t be reconciled with the consultants McKinsey’s estimate of $130 a ton in CCS demonstration costs. But the latter estimate assumes large costs in transport and storage. In May 2009, Brian Ricketts, coal analyst with the International Energy Agency, said that each CCS installation would cost “a billion euros” and funding was the biggest challenge.
Huaneng’s Shanghai project aims to capture 10,000 ton of CO2 per year from one of the company’s power plants, and it is the “next step to industrialising the process.”
But it is only a small fraction of the CO2 from the company’s Shanghai operations. The first use of the CCS post combustion technology at the company’s operations at Gaobeidian, on the outskirts of Beijing was even smaller capturing 3000 tons of CO2 a year.
Ever practical, Huaneng is endeavouring to market CO2, rather than going down the underground storage route. Jiang Minhua said that a market study suggested that selling 100,000 tons of CO2 in the Shanghai region will not be a problem. “That doesn’t include something else we are looking into-using the CO2 to boost extraction rates in nearby oil fields.”
Su Wei, director general of the climate change department at the National Development and Reform Commission told a Bloomberg reporter (August 4) that “carbon capture and storage, particularly for China, is not one of the priorities- the cost is an issue.”
Su Wei said that ” if we spent the same money for CCS on energy efficiency and the development of renewables, it would generate larger climate change benefits.”
Bloomberg (August 6 2009) reported that Su Wei, director general of the climate change unit at China’s National Development and Reform Commission(NDRC) said that “darbon capture and storage, particularly for China, is not one of the priorities- the cost is an issue. If we spent the m=same money for CCS on energy efficiency and the development of renewables, it would generate larger climate change benefits.”
