| Abstract: | China possesses rich resources of renewable energy. Developing renewable energy technologies is becoming more mandatory to reducing environmental pollution, greenhouse gas emission and replacement of fossil fuels. Relative to fossil fuels, the energy density of various renewable energy resources is low and scattered, and renewable energy systems are difficult to utilize in a concentrated way. Distributed use of heat by integrated renewable energy is a scientific way of energy utilization-the energy efficiency is high, in harmony with the environment, and changes traditional energy use patterns. Distributed energy systems are arranged around users in a small-scale decentralized way, and using renewable energy could supply energy to remote areas conveniently and safely. So distributed use of heat by integrated renewable energy is an important way to renewable energy consumption. The paper analyzes the overall capacity of distributed renewable energy for heat utilization from the fields of construction, industry and urbanization development. The demand growth of heating, cooling and electricity in construction field, the close relationship between huge energy consumption and heat utilization in industry, and the rapid growth of energy consumption brought by urbanization development have provided bright prospects of renewable energy utilization. At the same time, on the basis of energy requirements and technology developments, the paper analyzes the deployment potential of distributed renewable energy for heat utilization. The amount of alternatives to fossil fuels in construction field, the enhanced proportion of solar thermal utilization in industry, and the energy-saving potential in the field of urbanization are quantitatively evaluated. Furthermore, the paper elaborates the technology developing prospect and direction of renewable energy heat utilization technology including solar furnace, cross-season heat storage and supply and air-conditioning technologies by solar energy, wind energy heat pump technology, biomass heating technology. It also explains renewable energy cascaded utilization technology including solar cogeneration technology, biomass distributed CCHP technology, low-temperature multi-effect desalination technology based on renewable energy. Besides, the paper also expoundes renewable energy multienergy complementary and integrated utilization technology including solar photovoltaics and solar thermal integration technology, solar energy and biomass complementary distributed cogeneration technology, solar energy and alternative fuels thermochemical complementary CCHP technology. The paper draws the technology roadmap of distributed use of heat by integrated renewable energy. The roadmap plans developing directions of distributed renewable energy from three levels for the next 5 years, including heat utilization, cascaded utilization and integrated utilization, respectively. After the gradual maturity of distributed use of heat by integrated renewable energy technology, the scalable industrialization distributed renewable energy-related equipment manufacturing and others shall be promoted, and demonstration projects of a variety of renewable energy heat utilization and utilization technology shall be established and promoted to form the energy supplying mode of comprehensive renewable energy consumption. By 2030, the proportion of distributed use of heat by integrated renewable energy in the primary energy consumption sector is projected to reach "6%-9%", and the future direction of energy structure is expected to gradually shift to the dominance by renewable energy. Finally, the paper presents the developing initiatives of distributed renewable energy. This study clearly puts forward that the industry will be the main area to promote the proportion of renewable energy;technological innovation shall become an important way to give a full play to the potential of distributed use of heat by integrated renewable energy. Solar furnace, biomass gasification, integration of solar thermal and solar photovoltaic technology shall become the focus of future research and development. We shall promote new industries of distributed use of heat by integrated renewable energy in order to improve the overall technological level and international competitiveness of China''s energy industry. Supporting policies such as financial subsidies, tax incentives, low-interest loans and other policies shall be provided to promote the coordinated development of distributed renewable energy and the predictive ability of distributed renewable energy development by country and industry associations. |
