On November 14, National Cheng Kung University’s Office of Research and Development collaborated with the NCKU Research Center for Energy Technology and Strategy and the Hierarchical Green-Energy Materials (Hi-GEM) Research Center to hold a seminar on Sustainable Development Goal 7: Affordable and Clean Energy. Scholars and experts were invited to share their research and discuss a variety of topics, including energy resource circulation, energy resource education, industry–academy collaboration, smart energy, and energy-saving systems.
Tsair-Fuh Lin, Director of the Office of Research and Development, noted that in 2015, the United Nations announced 17 Sustainable Development Goals. In April 2020, the World University Impact Ranking released by Times Higher Education ranked NCKU as 2nd in Asia and 38th worldwide. Of the 17 SDGs, NCKU was ranked top 100 in 11 goals. By using the SDGs as institutional development goals and sustainable development concepts as the core objectives for industrial development, NCKU has generated abundant research energy and obtained fruitful research results. In addition, the university has increased the investment of intramural resources to enhance its global influence and achieve the NCKU 2030 Vision.
The Hi-GEM Research Center, one of the seminar organizers, was established in 2008 and became a top university research center in 2011. Hi-GEM Director Ta-Hui Lin stated that Hi-GEM’s research capacity currently leads Taiwan in the following fields: (1) monitoring and maintenance of offshore wind farms; (2) flexi-fuel technology for energy saving and emissions reduction; (3) smart energy grid and energy storage; and (4) energy resources and policies. After the Aim for the Top University Project concluded, the research center continued operation using funding granted for other research projects to achieve financial autonomy. In the future, the center will cooperate with national energy transition policies and endeavor to become an internationally recognized research center.
The flexi-fuel team of the Hi-GEM Research Center presented its developed flexi-fuel technology for energy saving and emission reduction, including material and source classification, preprocessing, basic combustion analysis, industrial-grade burning test analysis, and fly-ash reuse. The team constructed Taiwan’s first 100 kW-grade oxy-combustion research furnace, which combusts solid and liquid fuel under pure oxygen conditions. Over 90% of the flue gas of this furnace is CO2. Recently, the flexi-fuel team has collaborated with the Industrial Technology Research Institute Green Energy and Environment Research Laboratories to construct a low-carbon energy and resource circulation science-based industrial park and create Taiwan’s first 600 kW dual-circulation fluidized bed power generation platform. Equipped with various technologies and equipment for testing fuel and combustion characteristics, the flexi-fuel team supports manufacturers in developing and testing various fuels and collaborates with furnace manufacturers by providing furnace sample designs, analyzing furnace parameters, and constructing systems for entire plants.
The circular economy team shared its contributions in various recycle and reuse technologies developed for circular resources and materials since 2017. The team assists domestic stainless-steel production index companies in achieving production goals, in enhancing the quality of generated furnace slag for reuse, in modifying the refining process, in flame resistance testing, in obtaining international certificates with products, and in integrating the industry chain. The team has established the Diverse Resource and Material Joint Research and Development Center to facilitate collaboration between NCKU and the US company Applied Environmental Technologies, Inc. The collaboration project used an academic approach to create a novel plastic waste recycling mechanism, and the circular economy team has applied the developed mechanism for international certification as the first closed recycling system for plastic products in the world.
Director Lin observed that since 2018, the Hi-GEM Research Center has implemented the Talent Cultivation for the Integration and Application of Clean Energy System, a program set up by the Ministry of Education. Due to Taiwan’s shortage of energy resources and inability to rely on single energy resources, the future trend of energy consumption will orient toward small quantities of reusable resources, or highly volatile reusable energy resources, diversified and regional energy applications. To anticipate this trend, the cultivation and training of energy system integration talents is necessary. To this end, the program connects with United Nation SDG 7: Ensure access to affordable, reliable, sustainable, and modern energy for all. It both advocates for the regional implementation of education for energy system integration talent cultivation and industry–academy collaboration and proactively invites collaboration between industry, government, and academic sectors. The program is planned to end in February 2021, to establish 11 cultivation bases, and to cultivate highly demanded talents in the energy sector through the cultivation bases and training courses on professional energy technologies.
Hong-Tzer Yang, a distinguished professor of the Department of Electrical Engineering and a deputy director of the Hi-GEM Research Center, shared the goals of Taiwan’s energy development policies and introduced the power market system and infrastructure planning. Yang proposed using user-end demand side management–related information, such as demand response and demand bidding, and operation plans that facilitate the service trade market as references for the optimization of distributed energy resources in energy management systems to obtain maximum efficiency. Key technology applications used in the development of user-end power management systems include smart community power management system frameworks, renewable energy generation forecasting, optimization, demand response, human¬ machine interfaces, blockchain distributed ledgers, smart contracts, and nonintrusive load monitoring systems. In particular, Yang’s research used the power management system located in Area C of the Shalun Smart Green Energy Science Park.
The Hi-GEM Research Center’s offshore wind farm observation and maintenance team is among Taiwan’s few wind farm maintenance teams and has five years of experience. The team is equipped the world’s first commercialized floating light detecting and ranging device. In addition to employing mobile monitoring technology using this device, the team collaborated with the Energy Research Centre of the Netherlands to introduce the European offshore meteorological mast technology and operation experience. The Hi-GEM Multifunction Building Design Team introduced how testing platforms for energy conservation buildings are designed, presented concepts on digital twin technology, and shared their current platform testing results and the application integration framework for digital twin technology to provide a reference for future system development.
To end the seminar, the Hi-GEM research team lead by Professor Chuan-Pu Liu introduced a recent production technology for nano-silica powder and research on its applications. The presented research outcomes included application of nano-silica powder as the anode material in lithium-ion batteries, carbon-silica powder, and hydrogen production fuel cells, thereby demonstrating the potential of nano-silica powder in energy-related applications. Subsequently, Associate Professor Wen-Dung Hsu shared a novel artificial intelligence smart technology—applying materials genome engineering to support green energy material design. Hsu’s presentation, entitled “Application of Computational Materials Science in Advanced Secondary Batteries,” shared the development and research results of high-pressure electrolyte, a topic highly anticipated in the industrial field. Chia-Chin Chang, Director of the Research and Development Center for Lithium-ion Battery and Dean of the College of Environmental Sciences and Ecology, National University of Tainan, delivered a presentation entitled “Development of Microgrid Chemistry Energy Storage Component in Lithium-ion Battery Technology” and shared methods for integrating the research energy of the Hi-GEM Research Center to develop green applications in electronic service vehicles and energy storage systems and, in turn, facilitate development in the energy storage industry.
