我国清洁能源碳减排效益分析及发展顺序

发展低碳能源是应对全球气候变化、实现电力低碳化发展的有效途径,最终要以发电技术在具体工程项目中应用来实现,衡量各技术的经济可行性、评价可再生能源发电技术CO2的减排效益是关键。分析了当前我国主要5种低碳发电技术置换火电的碳减排成本及产生的碳减排效益,并对2020年低碳能源发电技术的碳减排潜力进行了测算。结果表明,水电发电成本及相应的碳减排成本最低,核电其次,光伏发电最高,应优先发展水电、大力开发核电,同时积极发展风电等其他低碳能源。

Benefit Analysis of Carbon Emission Reduction and Development Order of Clean Energy in China

The development of low carbon energy is one of effective measures to address global climate change and achieve power low carbon development. Eventually, it has to achieve the application of power generation technology in the specific projects. It is the key to evaluate CO2 emission reduction benefit of renewable energy power generation technologies and the economic feasibility of each technology. This paper analyzes carbon emission reduction cost benefit of five main low carbon power generation technologies to replace coal fired power in China. And then, the carbon emission reduction potential of low carbon energy generation technologies in 2020 is estimated. The results show that the generation cost of hydroelectric power generation and the corresponding carbon emissions cost is lowest; the second is nuclear power; while photovoltaic power generation is the highest; therefore, it should give priority to development of hydropower and exploit nuclear power on a big scale; at the same time, it actively develops wind power and other low carbon energy.
