Energy Science &Engineering, Volume 14, Issue 5, Page 2499-2513, May 2026.Integration of a steam cycle with an existing gas turbine increased efficiency from 32% to 51%, reducing fuel consumption by 21.4% and CO2 emissions by 18.6%. The modification generated USD 13.9 million annual savings and lowered the Levelized Cost of Energy to 38.7 USD/MWh, with a 3‐year payback.

Energy Technology, Volume 14, Issue 4, April 2026.Heat‐pump charging of Carnot batteries with zeotropic large temperature glide CO2–alkane mixtures enables charging from ambient to ≈398.15 K with improved heat‐exchanger temperature matching at moderate pressure ratios. The highest COP occurs near xCO2 ≈ 0.15, whereas cost and throttling losses rise monotonically with CO2 content; butane isomers ...

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.ABSTRACT This study investigates binary zeotropic mixtures of R744 (CO₂) blended with eco‐friendly refrigerants for medium‐high temperature heat pumps, comparing them with conventional R744/R134a systems. All mixtures meet 60–80 K temperature lift requirements under low‐temperature conditions. A genetic algorithm optimized system parameters using fixed

AIChE Journal, Volume 71, Issue 11, November 2025.Abstract In this work, we present the first algorithm for identifying the minimum reboiler vapor duty requirement for a general multi‐feed, multi‐product (MFMP) distillation column separating ideal multicomponent mixtures. This algorithm incorporates our recently developed shortcut model for MFMP columns.

Pareto‐Optimal Treatment of Uncertainties in Model‐Based Process Design and Operation
Chemie Ingenieur Technik, Volume 97, Issue 11-12, Page 1057-1064, November 2025.It is described how to handle here‐and‐now (i.e., process design‐related) and wait‐and‐see (i.e., process operation‐related) decisions in a multicriteria framework. This approach exploits the adjustability for the wait‐and‐see variables while at the same time respecting optimality guarantees on process key performance indicators.
