Forceful push for clean energy

CHINA is expected to develop its coal conversion industry into the world's largest by 2020 as the world's biggest coal producer and consumer is seeking clean use of its huge coal resources, industry insiders forecast.

"China's capacity of coal liquefaction projects would hit the equivalent of 20 million tons of oil, that of coal-to-gas would reach 50 billion cubic meters, and coal-to-chemical 10 million tons of oil equivalent," Du Minghua, deputy director of China Shenhua CTL & CTC Research Institute, said at an energy forum over the weekend in Taiyuan, capital of Shanxi Province.

The scale would then become the largest in the world, he noted.

Du said China so far has finished construction of eight pilot clean coal conversion projects. Annual coal liquefaction capacity stands at 1.68 million tons, and that for coal-to-gas at 15 billion cubic meters. The capacity for coal-to-olefin stands at 1.7 million tons.

China has large deposits of coal but lacks oil and gas.

Coal is used for power generation in China but this causes severe pollution, said Wang Jianguo, director of the Shanxi Institute of Coal Chemistry of the Chinese Academy of Sciences.

"For China, coal is dominant in the energy mix not only at present but will be in the coming 40 to 50 years," said Ni Weidou, an academician at the Chinese Academy of Engineering,

China would rely more on coal for power generation, he said, noting clean utilization of coal would be the key for China to develop a low-carbon economy.

China should better use coal-produced liquid fuel and chemical products to make up for the shortage of oil, Wang said.

Developing the clean coal conversion sector would help China reduce its emissions of carbon dioxide because it is easier to capture and store during the process than during direct burning. It would help the country to meet its target of cutting the intensity of carbon dioxide emissions per unit of gross domestic product in 2020 by 40 to 45 percent from the 2005 level, experts said.
