Background
Through primarily state-driven research and development and technology acquisition efforts beginning in the late 1990s, China transformed its coal-fired power plant fleet, reducing the average amount of coal required per unit electricity by 19% over the period 2000-2014. It now surpasses the U.S. in terms of average efficiency, and the large-scale government science and technology programs responsible for these achievements have attracted significant attention and positive appraisal. Yet, the adopted standardized designs often achieve suboptimal efficiencies due to low and fluctuating use in operation. The divergences between design and operation reveal one of several drawbacks with state-directed innovation programs. These are explored in the context of the political economy of China’s power system, where centralized targets and technology development plans are made at arms-length of the highly localized system planning and operation functions.
Methods
A review of the Chinese and English literature on the topic is combined with semi-structured interviews conducted in China in 2015-2016 with advanced coal technology program experts and electricity system operators.
Results
Figure - Interactions of coal power technology development and deployment processes and electricity systems planning and operation
Key features of China’s electricity sector such as volatile demand growth, underdeveloped power markets and significant political intervention have caused the suboptimal use of advanced coal units. The complexities of operational conditions are largely ignored in the small set of metrics that characterize technology development plans, which may assume for political and other reasons a set of ideal benchmark conditions (e.g., high economic growth leading to steady utilization). Further, the centralized targets and technology development plans made at arms-length of localized system operation have led to difficulties in addressing these concerns in subsequent designs, leading to increased costs, emissions and political frictions.
Conclusions
Examining the case of China’s coal upgrading program, this work speaks to the successes and shortcomings of state-directed innovation programs that coordinate scientific activity within hierarchies of state-defined goals, as opposed to more localized and/or less structured approaches to research and development. This has implications for targeted advanced technology development in multiple contexts, highlighting the need to consider various usage conditions and the limitations of directed science for political aims. Within China, ongoing programs such as 700C advanced ultra-supercritical boiler development as well as proposed policy fixes to the current challenges, including the adoption of limited markets, do not fully address these difficulties. Harmonization of provincial institutions and the modernization of regulatory and policy frameworks will be necessary to capture more of the benefits of advanced coal power plant technologies.
