Biography
Shubham Tiwari is an energy systems modeler and a research scholar in the Agriculture, Forestry, and Ecosystem Services Research Group of the IIASA Biodiversity and Natural Resources Program. He leads the development of the BeWhere model, a spatially explicit, bottom-up, techno-economic optimization tool designed to determine the optimal geographical placement of renewable technologies and assess the energy systems at the supply chain level. The model has been applied across diverse research domains, including direct air capture (DAC) and green hydrogen-based e-fuel development, bioenergy, algae production, solar and wind energy integration, negative emissions technologies, and urban public transport electrification while including the constraints on ecosystem services.His current research focuses on evaluating the technical feasibility and market potential of sustainable aviation fuel (SAF) deployment across specific regional and national case studies. Additionally, he is actively engaged in developing prominent carbon dioxide removal (CDR) pathways, particularly bioenergy with carbon capture and storage (BECCS) and DAC, to support long-term decarbonization strategies. Furthermore, he is working on renewable energy expansion roadmaps while considering nature restoration and ecosystem services as important constraints.
Tiwari earned his PhD from the Department of Sustainable Energy Transition at the Asian Institute of Technology, Thailand, in 2023. His doctoral research focused on developing a co-optimization framework for multi-energy systems and sector coupling, integrating Power-to-X (P2X), hydrogen storage modeling, carbon storage, and carbon markets to analyze pathways for low-carbon energy transitions.
Beyond research, Tiwari enjoys outdoor sports, particularly tennis, badminton, and swimming.
