SgEC Webinar on “Hydrogen and Fuel Cell Technologies – A bridge towards a more sustainable future” took place on 11th November 2021 10 am SGT. Prof. Chan, who is Professor and President’s Chair in Energy at NTU, shared the evolution of energy use, the concept of energy storage for energy and power intensive applications, as well as the fuel cell and electrolyzer in connection to the renewable energy.
From the Thermodynamics perspective, a city or a nation can be seen as a thermodynamic system, and more specifically described by the concept of a control volume, whereby the energy in terms of heat (cooling and heating), work (electricity) and mass (oil and gas) are transferrable through the system boundary. Under the steady-state condition, the summation of these transferable energies is equal to zero, signifying that these energies are convertible from one another to fulfill a particular state of requirement. Unfortunately, the total energy requirement of a control volume is dynamic or transient all the time, hence an energy storage is inevitable. Hydrogen is a chemical energy. It is not only an energy carrier but also an ideal energy storage. Hydrogen and fuel cells are technologies that can govern the heat, work, mass, and energy storage in a thermodynamic system. This webinar will first present the evolution of energy use, then the concept of energy storage for energy and power intensive applications, and finally the fuel cell and electrolyzer in connection to the renewable energy.
