Comparison of single and double stage regenerative organic rankine cycle for medium grade heat source through energy and exergy estimation

International Journal of Renewable Energy Development, 2019
Regenerative organic Rankine cycle (RORC) can be used to improve organic Rankine cycle (ORC) performance. This paper presents a comparison of a single (SSRORC) and double stage regenerative organic Rankine cycle (DSRORC) using a medium grade heat source.

Optimizing Building Energy Systems Using Generalized Disjunctive Programming: Improving Model Precision and Decision‐Making Efficiency

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This paper examines the optimization of building energy systems (BESs) through the lens of generalized disjunctive programming (GDP), a methodology that streamlines the modeling of intricate logical structures and discrete decisions. The study concentrates on three pivotal aspects of BES optimization: the imposition of minimum part‐load constraints ...

Cost Analysis and Optimization of Green Hydrogen Production via Concentrating Solar Technologies and PEM Electrolyzer

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
The burgeoning demand for power across the globe and the disastrous effect of climate change that results from power generation through depleting unclean fuel sources have necessitated the use of renewable and clean fuels. Hydrogen is a good alternative but only when produced from low‐carbon energy resources.

Working fluid selection of Organic Rankine Cycles

Energy Reports, 2020
Organic Rankine Cycles (ORCs) are identified as one of the best candidates to generate electricity from low-grade heat sources. ORCs operate on low temperatures and low pressures with comparative to conventional Rankine Cycles. Therefore, organic fluids or refrigerants can be used as the working fluids for ORC applications, instead of water, which is ...

Techno‐Economic Assessment of Green Hydrogen Production Using Supercritical Geothermal Energy and Solid Oxide Electrolysis

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Green hydrogen uses renewable energy to power electrolysis and dissociate water into hydrogen and oxygen, making it an environmentally sustainable alternative to grey and black hydrogen, which both require fossil fuels (using natural gas and coal, respectively).

FLUOROETHERS AS A WORKING FLUIDS FOR LOW TEMPERATURE ORGANIC RANKINE CYCLE [PDF]

Problems of the Regional Energetics, 2014
Hydrofluoroethers as a new class of working fluids for the organic Rankine cycle have been considered to utilize the low-potential waste heat. Temperature range 300…400 K was chosen to provide energy conversion of waste heat from fuel cells.
