First of all, Prof. Chunhua Zheng from Automotive Electronics Research Center of SIAT introduced the cooperation background with Prof. Cha. They've known each other for more than ten years, both parties have been focusing on the research of hybrid energy storage system in Korea.

This year, through CAS-PIFI project, Prof. Cha comes to China to continue their cooperative research.

"Hydrogen can be used to power vehicles, generate electricity, power industry and heat our homes and businesses;" said Prof. Cha, "it could make a huge difference on our carbon emissions, and will be critical to achieving net zero."

In addition to scientific research, during his academic career, he had traveled and visited nearly 70 countries and cities, and he wherever he goes, he will taste the local beer, which contributed the critical thinking for his life. 

Prof. Cha's talk sparked strong interests from students and researchers, they raised some questions about the carbon neutral and application scenarios of hydrogen, Prof. Cha shared his thoughts and understanding from his personal experiences.
