About Professor Romagnoli
Professor Alessandro Romagnoli is a recognised expert in mechanical and energy systems engineering. He earned his PhD in Mechanical Engineering from Imperial College London, where his early research focused on turbine aerodynamics, waste heat recovery, and sustainable propulsion systems.
Since joining NTU in 2013, he has held leadership positions including Assistant Dean for Innovation and Enterprise, Cluster Director at the Energy Research Institute (ERI@N), and Co-Director of the NTU–Surbana Jurong Corporate Lab. He also established the Thermal Energy Systems Lab, which focuses on integrated energy solutions such as cryogenic storage, geothermal energy, and cold-economy systems.
Beyond academia, Professor Romagnoli advises respected institutions including the International Finance Corporation (IFC), the Asian Development Bank (ADB), Breakthrough Energy, and the European Research Council.
What You’ll Learn
Professor Romagnoli’s video series explores the pathways to energy transition. From understanding carbon emissions to unlocking geothermal power and improving everyday habits, his sessions connect large-scale innovations with simple, actionable steps. Viewers will gain a clearer sense of how science, technology, and behaviour together shape a more sustainable energy future.
Professor Romagnoli shares his journey from Italy to Singapore and his work at NTU on systems that accelerate the global energy transition. With a background in mechanical engineering from Imperial College London, his research focuses on decarbonisation in energy and transport to support a more sustainable future.

In this session, Professor Romagnoli examines the urgent need to decarbonise the energy sector and the role geothermal can play in that transition. He explains how new drilling technologies could unlock geothermal power in countries beyond volcanic regions, providing a constant and reliable source of clean energy to complement solar and wind.
watch
Professor Romagnoli explains how energy demand, efficiency, and fuel choice combine to drive carbon emissions. He shows why cutting demand, shifting to renewables, and using carbon capture are critical steps toward net zero.

Professor Romagnoli highlights how small, everyday habits, from air conditioning and lighting to charging devices and digital storage, add up to major energy waste. He shows how simple changes in households and online behaviour can cut costs and support wider decarbonisation efforts.
watch
Professor Romagnoli shows how simple daily actions, like adjusting aircon settings or reducing energy waste, can scale into major national savings. He explains how these choices cut household bills, strengthen energy systems, and help drive the broader transition to a cleaner, more resilient future.
