Dr Amr Omar is a senior postdoctoral research associate at the School of Mechanical Engineering at UNSW, with a research portfolio that bridges sustainable energy and water systems. His work focuses on decarbonising water-intensive processes using solar-driven technologies, with applications in desalination, PVT, green hydrogen production, evaporative cooling, data centres, and membrane-based nanobubble generation techniques.

He has served as Chief Investigator on multiple industry and government-funded projects, including the development of solar PVT heat pump systems, evaporative cooling roadmap, membrane distillation for carbon capture, and nanobubble irrigation technologies. His contributions have led to the deployment of pilot plants, strategic planning reports for the NSW government, and the creation of the first in-situ Flocculant Strength Instrument, now operational at the Nepean Water Treatment Plant.

Dr Omar’s research also addresses critical infrastructure and policy gaps in data centre development, including water-energy feasibility mapping, waste heat recovery using MED systems, and benchmarking water use efficiency (WUE) across climate zones. His work aligns with the UN Sustainable Development Goals, particularly SDG6 (Clean Water) and SDG7 (Affordable and Clean Energy).

In addition to his research, Dr Omar is a dedicated educator, teaching subjects such as Solar Thermal Engineering, Sustainable Energy, and Material and Energy Balances. He has supervised over 20 thesis students (as well as exchange and industrial students), including HDRs working on solar-driven desalination, hydrogen systems, and concentrated PVT optimisation. His mentorship has led to award-nominated student research and international conference presentations.

Dr Omar actively engages with industry and the public through keynote talks and public outreach. He is a member of the Early Career Academic Network Committee, a reviewer for top-tier journals and international funding bodies (Chilean Research Agency (ANID)), a member of interview panels for rural scholarships, and a contributor to health and safety initiatives at UNSW. His work has been featured in Water Desalination ReportThermopedia, and HelioCSP, and has earned him multiple awards, including the Malcolm Chaikin Prize for Research Excellence, Asian Union of Thermal Science and Engineering Young Scientist Award Nominee, and Research Excellence Award (ECA) Nominee.

Dr Amr Omar’s research focuses on advancing sustainable water and energy systems through solar-driven technologies, with a strong emphasis on real-world application and infrastructure integration. His work spans membrane distillation, multi-effect distillation, green hydrogen production, and nanobubble technologies, all aimed at decarbonising water-intensive processes and improving resource efficiency.

He currently leads several externally funded projects, including:

  • Solar PVT Heat Pump Optimisation for aquatic centres, with commercial deployment at the North Sydney Olympic Pool.
  • The Evaporative Cooling Roadmap for Regional NSW, addressing climate-resilient cooling strategies.
  • nanobubble irrigation pilot for turf farms, translating lab-scale innovations into field-scale drought resilience solutions.

 

He also investigates infrastructure and policy gaps in data centre development with current thesis projects:

  • Water and energy demand modelling for data centres across Australian climate zones, including GIS-based feasibility mapping and utility engagement frameworks.
  • Waste heat recovery using MED systems, evaluating the potential to repurpose thermal energy for water production and establishing water-use efficiency (WUE) benchmarks tailored to local conditions.

 

His research has led to the development of Australia’s first in-situ Flocculant Strength Instrument, now operational at the Nepean Water Treatment Plant, and has informed strategic planning at the state level through government reports and workshops. Collaborating with institutions such as NSW DCCEEW, DPIRD, RACE for 2030, CSIRO, and Sydney Water, Dr Omar’s work contributes to both academic advancement and societal impact, aligning with SDG6 (Clean Water) and SDG7 (Affordable and Clean Energy).
