Energy System Modeling for a Sustainable Economy Advisors: Prof. Rakesh Agrawal, Prof. Mohit Tawarmalani

  • Developed and rigorously simulated a family of novel solar thermal power generation cycles with calculated unprecedented efficiencies using integrated Aspen Plus and Matlab modeling environment.
  • Developed and implemented strategies to efficiently coproduce hydrogen and electricity from solar energy. Developed and optimized solar thermal hydrogen and power coproduction processes using integrated Aspen Plus and Matlab modeling environment. Integrated hydrogen power cycle with hydrogen and power coproduction process for continuous and efficient solar power supply.
  • Identified process options to convert biomass and natural gas to liquid fuel. Created a superstructure optimization problem that is simulated and optimized in Aspen Plus. Mathematically formulated the process superstructure as a Mixed Integer Nonlinear Program in GAMS and solved to global optimality using optimization techniques. Formulated and solved optimization problems to determine parameters from multiple experimental results for biomass conversion processes.
  • Designed and performed detailed process simulation of dimethyl ether closed loop large scale storage cycle, which include optimization of mixed refrigerant refrigeration cycle, design of cryogenic carbon capture and purification, detailed simulation of solid oxide fuel cell and solid oxide electrolysis cell.
  • Designed and performed detailed process simulation of multi stage flash (MSF) desalination processes for large scale fresh water production.
  • Explored energy efficient synergistic interactions at process and end use levels, and their potential impacts on policy formulation.
