The ORC (Organic Rankine Cycle) system is based on an innovative closed thermodynamic cycle for the flexible and distributed production of electric and thermal power. This ORC technology is particularly suitable for distributed generation close to the point of energy use, utilizing turbogenerators that convert thermal energy into electrical
The Rankine cycle was named after him and describes the performance of steam turbine systems, While many substances could be used as the working fluid in the Rankine cycle (inorganic or even organic), water is usually the fluid of choice due to its favorable properties, such as its non-toxic and unreactive chemistry,
For the majority of the organic Rankine cycle (ORC) working fluids, the expansion process is completely dry, thus blade erosion issues in turbines and inherent expansion inefficiency due to condensation are avoided. Several ORC working fluids are also suitable as a lubricant for rotating machinery, thus further simplifying the system.
Organic Rankine cycles can help to reduce that impact, as they can be operated by using the industrial waste heat of renewable energies. The present study presents a comprehensive bibliographic

Organic Rankine cycle. The organic Rankine cycle (ORC) uses an organic fluid such as n-pentane or toluene in place of water and steam. This allows use of lower-temperature heat sources, such as solar ponds, which typically operate at around 70 –90 °C. The efficiency of the cycle is much lower as a
The last decade (2013–2023) was the most prolific period of organic Rankine cycle (ORC) research in history in terms of both publications and citations. This article provides a detailed review of the broad and voluminous collection of recent internal combustion engine (ICE) waste heat recovery (WHR) studies, serving as a necessary
It has been demonstrated that energy systems driven by conventional energy sources like fossil fuels are one of the main causes of climate change. Organic Rankine cycles can help to reduce that impact, as they can be operated by using the industrial waste heat of renewable energies. The present study presents a
The organic Rankine cycle is is similar to the Rankine steam cycle, but uses an organic fluid such as refrigerants and hydrocarbons instead of water as the working fluid. The ordinary Rankine cycle uses thermal power to convert water to steam, which expands through a turbine in order to generate electricity.The organic Rankine cycle

The organic Rankine cycle (ORC) uses an organic fluid such as n-pentane or toluene in place of water and steam. This allows use of lower-temperature heat sources, such as solar ponds, which typically operate at around 70 –90 °C. The efficiency of the cycle is much lower as a result of the lower temperature range, but this can be worthwhile because of the lower cost involved in gathering heat at this lower temperature. Alternatively, fluids can be used that have boiling point
