The carbon-neutral technology system needs to cover the full range of greenhouse gases and take into account both supply-side and consumer-side emission reduction needs.
Technology system construction is different from technology classification. Technology system construction seeks the unification of technology system classification and technology optimization combination to achieve the goal. Technology classification is often a process of distinguishing technologies by setting standards.
The construction of Chinese carbon neutralization technology system consists of the following aspects.Energy saving, efficiency and low carbon technology: reduce the carbon emission intensity of energy consumption and promote the development of clean energy. It includes clean and efficient utilization of fossil energy, coal gasification combined cycle power generation, ultra-high parameter ultra-supercritical power generation technology, and energy conservation, emission reduction, quality improvement and efficiency improvement technologies in industry, agriculture, construction, transportation and other fields.
Zero-carbon electric energy technology: complete zero-carbon transformation of supply side electricity production and transmission, promote the transformation of power system, and provide the basis for end-use electrification. Including renewable energy power and nuclear power technology, energy storage technology and transmission and distribution technology.
Zero-carbon non-electric energy technology: It is mainly used to solve the problem that the power density is not enough and can not be stored. It is the supplement of electric energy and forms zero-carbon energy system together with it. Including hydrogen energy, zero carbon non hydrogen fuel, heating technology and so on.
Fuel feedstock replacement technology: Solve the problem of fuel and feedstock replacement technology and process, and use process improvement and technological change to provide low carbon and zero carbon products. Including fuel substitution technology, raw material substitution technology, industrial process innovation and reengineering technology, resource recovery and recycling technology.
