“…Devastating incidences of wildfire and flooding being experienced around the globe today are testaments to the adverse effects that climate change tends to pose on man and the environment. [1][2][3][4] No doubt, the emission of carbon and other obnoxious gases from the combustion of fossil fuels is among the principal causes of global warming. 5 It is therefore logical that efforts aimed at mitigating the global warming effects must keep in view the possibilities of eliminating or at least reducing the combustion of carbonrich fossil fuels.…”

This study was aimed at comparing the exergetic sustainability and exergoenvironmental performance of subcritical (SUBORC) and supercritical (SUPERORC) organic Rankine cycle (ORC) plants for waste heat recovery from a marine vessel engine. A liquid-gas shell-and-tube heat exchanger was employed to recover the engine exhaust gases’ thermal energy. The hot exhaust gases flowing through the gas side heat the Therminol 66 heat transfer fluid employed on the liquid side, which in turn heats the ORC working fluid (R600a). Zero-dimensional mass, energy, and exergy balance equations defined by the Laws of Thermodynamics were implemented in MATLAB for the design of the two ORC configurations. Results showed that the evaporator and the preheater are the most sustainable components with exergetic sustainability index (ESI) values of 7.7 and 39.4 for the SUBORC and the SUPERORC, respectively. Additionally, the condenser was obtained in both cases with the worst environmental performance with exergoenvironmental impact of electricity (EIE) values of 12 and 13 eco-indicator points per 1 MW of electricity produced by the SUBORC and the SUPERORC, respectively. Moreover, results showed that a switch from the SUBORC to the SUPERORC would have an insignificant effect on the ESI at the system level; it would reduce the recoverability ratio by about 4%, from about 0.47 in the SUBORC to around 0.45 in the SUPERORC; and it would reduce the EIE by 1.4 Pt/MW. In sum, a supercritical ORC system would exhibit better exergetic environmental sustainability than a subcritical one for waste heat recovery from a marine vessel engine.

In the present study, we have evaluated the extreme precipitation and temperature indices over the 10 agro-climatic zones falling under Ganga River basin (GRB)utilizing a high resolution daily gridded temperature and precipitation multi-model ensembled CMIP6 dataset (0.25°x0.25°) under global warming levels of 1.5°C, 2°C, and 3°C.We found that annual daily minimum temperature(TNN) showing higher rise of about 67% than maximum temperature (TXX)of 48%in GRB. The basin also experiences a greater increase in the frequency of warm nights (TN90P) of about 67.71% compared to warm days (TX90P) of 29.1% for 3°C global warming level.Along with extreme indices, population exposed due to the impact of the extreme maximum temperature has also been analysed for progressive warming levels. Population exposure to extreme temperature event (TXX) has been analysed with 20-year return period using GEV distribution method. The study concludes that exposed population to extreme temperature event experienced an increase from 46.99-52.16% for whole Ganga Basin. Consecutive Dry Days (CDD) and Consecutive Wet Days (CWD) both show a signi cant increasing trend, but CWD has signi cant increase in majority of the zones, while CDD show signi cant decreasing trend for some of the zones for three warming levels periods.Extreme climate indices help to understand the frequency and intensity of the extreme weather events such as heavy rainfall, droughts, heatwaves etc. to develop early warning systems and adaptation strategies to mitigate such events.
