Dr. Mohamed is Clean Energy 4 Africa’s founder and director. He is also the founder and managing director of Terra Energy (the parent company of Clean Energy 4 Africa). He is a sustainable energy consultant and an expert and award-winning researcher with 8+ years of experience in the renewable energy field. Mohamed holds a Ph.D. in sustainable energy from Hamad Bin Khalifa University, Qatar.

Dr. Mohamed has strong experience in working with intl. organizations, utilities, and philanthropies in various energy transition projects in Africa and globally. He has worked with the Africa Enterprise Challenge Fund (AECF) and kFW Bank in conducting a comprehensive market assessment study for the Sudan SME Catalytic Fund, with an emphasis on SMEs working in the renewable energy and agribusiness sectors. He also worked with the Basel Agency for Sustainable Energy (BASE) in conducting a study on customer-driven business models that can scale up renewable energy and e-mobility in Morocco, Kenya, Nigeria, Ghana, Rwanda, and South Africa. Furthermore, he worked for three years as a technical expert with the Public Utility Company in Qatar, where he took part in developing the national renewable energy strategy for the country. Moreover, he worked as a research consultant for the Energy for Growth Hub, where he developed policy memos on the desalination market in Africa.

Mohamed completed his PhD, at 28 years old, at Hamad Bin Khalifa University (in Qatar), where he worked on developing a sustainable solar-driven seawater desalination technology. His PhD research, which received several prestigious awards, investigated the technical performance, environmental impact, and economic feasibility of solar-driven low-pressure thermal desalination, particularly for water-scarce countries such as Qatar. Dr. Mohamed has published numerous peer-reviewed articles in prestigious and high impact journals in renewable energy, desalination, and environmental sciences such as Desalination (Elsevier), Environmental Research Letters (IOP Publishing), and Energy Conversion and Management (Elsevier). Moreover, his PhD research received the “Best Green Sustainable Initiative” Award (2018) by the Ministry of Energy & Industry in Qatar. Mohamed completed a MSc. in Energy Technology from The National University of Malaysia and a BEng. Honors (in the First Class) in Mechatronics Engineering from The University of Nottingham.
