Exergy Efficiency of Closed and Unsteady-Flow Systems
A companion treatment extending systematic exergy efficiency definitions to closed and unsteady-flow systems, where boundary work, transient storage and finite reservoirs change how recovered and expended exergy must be accounted.

A Systematic Approach to Exergy Efficiency of Steady-Flow Systems
A general treatment of exergy efficiency for steady-flow systems, deriving explicit relations for turbines, compressors, pumps, nozzles, diffusers, valves and heat exchangers, as well as heat engines, refrigerators and heat pumps, with five equivalent formulations for power and refrigeration cycles.

Exergy as Criteria for Efficient Energy Systems: Maximising Energy Efficiency from Resource to Energy Service
An exergy-based optimisation model for a fully decarbonised national energy system, applied to Austria with 2030 renewable capacities. The work evaluates the technology mix that maximises exergy efficiency across both supply and final energy application.

Advanced Exergy, Exergoeconomic, and Exergoenvironmental Analyses of an Integrated Solar-Assisted Gasification Cycle
Advanced exergy, exergoeconomic and exergoenvironmental analysis of an integrated solar-assisted gasification cycle producing power and steam from heavy refinery fuels. Splitting destruction into avoidable and unavoidable parts localises where thermodynamic losses can realistically be recovered.

Exergetic Life Cycle Assessment: A Review
A systematic review of exergetic life cycle assessment across sustainability, energy systems and the built environment. The paper consolidates methods for resource accounting on an exergy basis, shows that exergy-based metrics provide an improved measure of sustainability, and identifies the opportunity for a more comprehensive exergetic LCA framework.
