Consultation on Biomass Power Generation Technology Improvement

Abstract Biomass resources are very abundant in China, with great energy potential. Energy utilization from biomass is an important way to national economic sustainable development on renewable energy, as well as reducing pollution to environment. Renewable Energy Law has been legislated in February 2005 in China, in which the development and utilization of renewable energy ranks priority item among Chinese energy development. CRESP cooperated between the State Development and Reform Commission of China and the World Bank aims at expanding and developing China’s renewable energy utilization to accelerate technological scale-up and industrialization process. CRESP office has entrusted and supported Guangzhou Institute of Energy Conversion (GIEC), CAS to make an elaborate analysis and assessment of cogency on the application of biomass electricity generation technology in China, which constitutes part 1 of this report, and is submitted to the Expert Workshop on “Analysis of Potential in China for Improvement in Biomass Power Generation Technology” of CRESP in April 2005. Based on the analysis and assessment, Experts and researchers participating in the conference discussed and expressed various opinions on some important points such as foreign and domestic relevant technologies and future development trend, biomass energy technological industrialization and which technologies are priority of industrial support and special measures. Everyone has the consensus that energetically developing biomass power generation technology is of importance to national sustainable development, particular to the wide rural and remote areas in China. The meeting summary constitutes part 2 of this report. As described in part 1, present key problem of scale-up utilization for biomass power generation technology is that China is very weak in general manufacture and production ability of biomass power generation related equipment. In order to advance China’s biomass power generation technology level and relevant energy equipment manufacturing ability, CRESP office particularly set up the Competitive Grant-in-aid Project according to GoC/ World Bank/ GEF, and entrust GIEC with the project implementation scheme, including the emphasis of technology advance items to be supported by ESCRP, qualifications for supported objectives and examination standard. These constitute part 3 of this report.

The Best Practices for Off-grid Solar Energy: A Case Study on China

Abstract While the beauty of solar energy is well known, there exist a lot of barriers to the greater use of photovoltaic solar home systems in meeting the basic power needs of the substantial population in developing world. Among them reviewed are purchase, delivery and maintenance related barriers in policy and institutional perpectives. A few good practices are examined accordingly. Finally, a case study on the development of solar PV of China are conducted, covering the current situation, the existing problems, the applicability of international practices and recommendations.

Alternatives to Fuel-based Lighting in Rural China-LED Lamps in Tibet

Abstract Despite high rates of electrification in China, 25 to 30 million people remain without access to electricity. This population, as well as those with only intermittent access, must rely on alternate sources of power for their lighting needs. This paper presents a comparison of available off-grid and grid-based lighting options in terms of performance and economics, which is then contextualized using a case study of semi-nomadic populations in rural Tibet. Fuel-based lighting is shown to be significantly more costly than solar-powered compact fluorescent lamps (CFLs) and solar-powered light-emitting diode (LED) alternatives per unit of lighting services delivered. We calculate that a hurricane-style kerosene lamp costs approximately $0.40 per thousand lumen hours (klmh) or $2.89 per thousand lux hours (klxh), while a solar-CFL lantern costs $0.17/klmh and $1.20/klxh and a solar-LED device costs $0.15/klmh and $0.03/klxh. Furthermore, as LED efficiencies continue to improve, solar-LED products will become even more economical. Three focus groups and 15 household interviews were held among off-grid populations in rural Tibet to gauge response to LED technologies. LEDs were universally ranked below CFL alternatives, primarily due to the directional nature of the LED devices exhibited, but were still ranked above all non-electric sources of light. Diffusing optics may thus need to be incorporated into solar-LED lighting systems before they are rated as more attractive for general illumination than solar-CFL systems. Accordingly, those surveyed placed a high value on the use of LED bulbs for flashlight applications. Finally, we note that despite the potential benefits of LEDs, market forces are not likely to spur innovation in solar-LED lighting options for the unelectrified populations of Tibet, as the design of these systems is dominated by the governmental bodies subsidizing their distribution. Unless this structure changes, the future development of LED-lighting technologies will depend on top-down investment from the central and local governments.
