 of renewable energy; and steadily improves the technology of power transmission at voltages of ± 800 kv DC and 1,000 kv AC and power grid safety technology.

— Enhancing equipment manufacturing level. The equipment manufacturing industry is the foundation of the development of energy technologies. China gives impetus to the technological progress of the equipment manufacturing industry through key state projects. The Chinese government encourages the development of comprehensive excavation machinery in coal mining, large comprehensive mining, hoisting, transport and washing equipment for underground coal mining, and heavy-duty open-pit mining machinery. It supports the development of complete sets of large equipment for coal chemicals as well as R&D of coal liquefaction and gasification, and coal-to-olefin conversion equipment, the development of high-efficiency and low-pollution power generation equipment, high-efficiency coal-fired power generation units, hydropower and pumped-storage units, heavy-duty gas turbines, PWR nuclear power generation units with a capacity of one million kw, high-power wind-driven generators, and superhigh-power transmission and transformation machinery. It encourages the development of oil and natural gas prospecting and drilling equipment and support equipment for large offshore oil projects, crude oil carriers with a capacity of 300,000 dwt, liquefied natural gas carriers and high-power diesel engines.

— Strengthening frontier technology research. Frontier technology, as a new potential driving force for energy development, can blaze the way for the leapfrogging development of energy industry and technologies. China focuses on research into conversion from fossil, biomass and renewable energy resources to hydrogen, and high-efficiency hydrogen storage, transmission and distribution technology. It also conducts research into the technology for the manufacturing of basic and key components of fuel cells, integration of fuel cell stacks, fuel cell power generation and automotive fuel cell power systems, and strives 28
