Abstract
This paper reviews the development of South Korea’s national research and development (R&D) in graphene technology, focusing on projects that have been classified as “green” technology. A total of 826 projects (USD 210 billion) from 2010 to 2019 were collected from the National Science and Technology Information Service (NTIS), which is full-cycle national R&D project management system in South Korea. Then we analyzed its R&D trend by conducting diverse text mining methods including frequency analysis, association rule mining, and topic modeling. The analysis suggests that the number of graphene green technology (GT) R&D projects and the research expenses will show a rising curve again in the incumbent government along with the implementation of the Korean New Deal policy, which integrates the Green New Deal and the Digital New Deal.
Highlights
International competitiveness in research and development (R&D) is a national strength and a key to sustainable national development [1,2]
Green New Deal is a socio-economic paradigm, which means the policy of converting the current energy policy centered on fossil energy into new one that is centered on renewable energy to create a low-carbon economy and increase employment and investment at the same time
The trend in total R&D expenses for graphene green technology (GT) R&D projects showed the same trend as the number of projects (Figure 1)
Summary
International competitiveness in research and development (R&D) is a national strength and a key to sustainable national development [1,2]. On 14 July 2020, the South Korean government introduced the “Green New Deal” policy whereby it would spend KRW 73.4 trillion (USD 60.9 billion) and create 659,000 jobs. The South Korean government announced its aim to reduce the net carbon emissions to zero (Net Zero) by 2050, for example, by supplying 1.13 million eco-friendly vehicles and creating 230,000 energy-efficient buildings. In the Green New Deal policy, the central concern is electricity supply [4]. As the markets for new and renewable energy and electric vehicles grow rapidly, and the limitations of fossil fuels and energy problems continue to emerge, the importance of high-capacity energy storage technologies for efficient energy use and response to climate change is greatly emerging. Researchers are considering graphene-based technologies for application in the green industry
