In February 2008, the Research Center for Energy Technology and Strategy (RCETS) was established by the National Cheng Kung University (NCKU), with the goal of organizing the university's researchers and resources in energy related fields. RCETS has created thirty-two research groups that focus on a wide variety of energy technology, including most importantly solar cells, energy strategies, bio energy, wind power, LED lighting, carbon capture and storage, and hydrogen systems. These groups represent eight colleges and thirty departments at NCKU, along with thirty off-campus research institutes and companies. Approximately 200 NCKU professors and researchers are involved. Since 2011, RCETS has become one of the four most prominent research centers at NCKU. In 2017, in consideration of international research trends and the main national energy policy development, RCETS readjusted six key technologies, including smart grid (smart grid and energy storage), offshore wind power (offshore wind farm observation, operation and maintenance), microalgae biomass energy (microalgae carbon fixation and water purification), flexi-fuel energy saving and emission reduction (flexi-fuel energy saving and emission reduction and circular economy), composite buildings (multifunctional building design), and energy strategies (energy strategies and policies).
