ABSTRACT

Korea is vulnerable to oil price volatility due to its significant energy import dependence, which accounts for almost 97% of the primary energy consumption. Korea ranked eighth worldwide in terms of the volume of oil consumption in 2014 according to the BP statistical review 2015. Consequently, the best way to address the energy problem in Korea and enhance its national energy security is to implement a mid-term strategic energy technology development plan supported by the Korean Research Council for Public Science and Technology, along with well-focused research and development (R&D). We thus established a mid-term strategic energy technology development plan for the five years from 2007 to 2011, which serves as a guide for producing focused R&D outputs and outcomes, and provides a continuous energy technology development policy for coping with the significant government scientific and technology policy shift toward a world class research institute. This paper applies data envelopment analysis (DEA), a multi-criteria decision-making approach, to measure the relative efficiency of nine selected energy technologies included in the mid-term strategic energy technology development plan, from an economic viewpoint, from 2007 to 2008. As policymakers, we need to analyze and determine whether nine energy technologies have to be carried out continuously or not by considering the R&D performance of the nine selected energy technologies is competitive under limited R&D investment and resources. Using the DEA approach, energy technology R&D programs can be thus effectively assessed in relation to the relative efficiency of the nine selected energy technologies. Two core technologies, namely redox flow battery (RFB) and combined heat and power plant (CHP), need to enhance their R&D outputs and outcomes to become relatively efficient technologies from an economic viewpoint. The government and energy policymakers can re-evaluate their status and enhance any weak points towards strategically shifting to a world-class research institute within five years.

Conclusion

The mid-term strategic energy technology development plan was launched by the Korean government, targeting a well-focused R&D performance and creating a world-class research institute within five years. We focused on analyzing the relative efficiency of nine selected energy technologies in the mid-term strategic energy technology development plan for determining whether the current Korean mid-term strategic energy technology development plan should be carried out continuously as plan with the R&D limitation. Before we carry out the third year plan of it with the limited R&D budgets, Korean policymakers have to measure the relative efficiency of the nine energy technologies whether the R&D status of the selected nine energy technologies is on the efficiency frontier group or not and enhance the weak points of them. We applied DEA to measure the relative efficiency of the nine selected energy technologies considering R&D budget limitations, R&D outputs and outcomes. As a result, seven energy technologies, that us, synfuel oil production technology, CO2 capture process technology using sorbents, CO2 capture technology of oxygen combustion, offshore wind power technology, solid-state DSSC technology, PEMFC core, and applied technology and production processes of high purity hydrogen, and core storage technology using natural gas were included in the efficient frontier group regarding the production of efficient outputs and outcomes in view of the mid-term strategic energy technology development plan. On the other hand, the status of RFB and CHP technologies must be re-evaluated in terms of their performance to produce more competitive outputs and outcomes comparing with the other seven technologies. This can be done by changing the outputs and outcomes, including the numbers of overseas patent registrations, overseas papers, and technology dissemination in terms of RFB and CHP technologies. Sensitivity analysis shows that the increase in the quantity of overseas patents, papers, and technology transfers by changing one and two of them can move them to the efficiency group.
