Energy storage Wind and the sun are intermittent energy sources, and affect the
technology stability of the power grid. Hence, the power grid has limited
capacity for such kind of energy. Efficient storage technology needs
to be developed. At present, this technology is in the hands of
European countries and the United States. The technology is still in
the R&D stage.
Carbon Taking into account China’s coal-based resource endowment, CCS
capture and technology will be of great significance to mitigation. Currently,
storage (CCS) there has not been a commercial demonstration of CCS technology.
technology The research is still in the preliminary stage, and a long way from
large-scale commercial implementation. China needs to do joint
R&D and keep track of the latest developments. In addition, China
needs to study both pre-combustion carbon capture and post-
combustion carbon capture technologies.
Coke dry By the end of May 2008, 57 units of CDQ devices have been
quenching put into operation in China, accounting for 13.5% of the total
(CDQ) coke production capacity (360 million tonne). Most of the CDQ
techniques in China were imported. Domestic metallurgical coke
design institutes such as Capital Steel & Iron Design Institute and
Anshan Coking & Refractory Engineering Institute have the capacity
to design a CDQ process, and some are able to manufacture CDQ
equipment, but they still lack the capacity to design and manufacture
high-pressure CDQ technology, which is in the hands of Japanese
companies.

Steel recovery and steel sector is low (only 45.6%), while advanced international
technologies enterprises, such as Japan’s Nippon Steel can have a recovery rate
of more than 92%. Thus, there is great potential for China’s iron and
steel industry to improve its waste recovery rate.
Coal moisture CMC has great mitigation potential and have been developed

technology of CMC. In China, however, only second-generation of
CMC is widely used.
