The Hong Kong and China Gas Company Limited (Towngas) has partnered with the E&M Young Ambassador Programme to launch the Towngas Green Flame Hydrogen City Design Competition, inviting upper primary school students to envision the future of hydrogen-powered cities through hands-on model design.
Participating teams are required to use hydrogen as the primary energy source, powered by hydrogen fuel cell technology.
The models must simulate practical applications within a future zero-carbon community, demonstrating functionality and feasibility rather than serving as static displays. Students are expected to illustrate how hydrogen energy could effectively replace conventional energy sources to achieve a sustainable, zero-emission vision.
The competition will be conducted in two main stages. Teams shortlisted in the first stage will take part in green hydrogen experimental workshops, where they will learn to produce hydrogen through water electrolysis.
Students will also visit Towngas headquarters to gain insight into the daily operations of an energy enterprise and observe real-world applications of hydrogen energy.
Teams that advance further will deepen their understanding of energy science and innovation technology by participating in hydrogen model car races and visiting the headquarters of the Electrical and Mechanical Services Department.
Finalist teams will then present their hydrogen city models, showcasing a range of potential applications for hydrogen energy in future urban settings.
Bien Wong Chun-cheung, assistant general manager of group ESG at Towngas, said the competition aims to inspire young students to think creatively about integrating hydrogen energy into their communities and to explore innovative green energy solutions.
“We hope the competition can enhance students’ interest in energy science and stimulate their potential in STEAM — science, technology, engineering, arts and mathematics,” he said.
Registration is now open to primary schools across Hong Kong, with each school allowed to submit one team comprising three to five students. The champion team will receive HK$10,000 in book vouchers and a trophy, while the first and second runners-up will receive HK$8,000 and HK$5,000 in book vouchers respectively.
