Biography
Yoga Pratama is a research scholar in the IIASA Energy, Climate, and Environment Program.Pratama joined IIASA in 2022. His research focuses on the role of CO2 removal (CDR) technologies in global climate change mitigation. He is particularly interested in how policy and technological innovation can accelerate the deployment of emerging technologies needed for deep decarbonization. He also contributes actively to the development of the MESSAGEix-GLOBIOM modeling framework.
His interests and expertise include energy systems modeling and analysis for expansion planning and market design, decarbonization strategies, natural gas and hydrogen infrastructure, and policy analysis. His work spans from corporate and asset-level studies to nationwide planning. He specializes in multi-scale modeling and optimization of energy systems to assess the role and value of clean technologies across different system characteristics, as well as the market and pricing mechanisms required for cost-effective pathways to net-zero emissions.
Prior to joining IIASA, Pratama gained extensive experience through research and consulting collaborations with institutions such as Kyoto University, the Coal Industry Advisory Board (CIAB), the International Energy Agency Clean Coal Centre (IEA CCC), the IEA Greenhouse Gas (IEA GHG) Research and Development Programme, and various energy companies in Indonesia and the UK. As part of these projects, he served as an expert in developing energy systems optimization models for applications including electricity system expansion planning, small-scale LNG supply chain design, natural gas pricing, and electricity market design. His experience spans modeling at both corporate/asset levels and national scales.
He received his PhD in Energy Systems Transitions from the Centre for Environmental Policy at Imperial College London, where he was also affiliated with the Sargent Centre for Process Systems Engineering. He holds a bachelor’s and a master’s degrees in chemical engineering from Universitas Indonesia and a master’s degree in energy systems engineering from the University of Michigan, USA.
