Reversible Heat Pump–Organic Rankine Cycle Systems for the Storage of Renewable Electricity

Energies, 2018
Storage of electricity from fluctuating renewable energy sources has become one of the predominant challenges in future energy systems. A novel system comprises the combination of a heat pump and an Organic Rankine Cycle (ORC) with a simple hot water ...

A Combined Thermal System with an Air-cooled Organic Rankine Cycle (ORC)

Energy Procedia, 2014
AbstractA combined heat and power (CHP) system with an air-cooled organic Rankine cycle (ORC) is proposed to relieve the shortage of the water resources. In the completely closed thermal system, the steam condenser of the power plant is simultaneously used as the evaporator for the ORC system, and the organic working fluid (OWF), R245ca, from the ...

Electricity from Waste Heat Using the Organic Rankine Cycle (ORC)

Energy Exploration & Exploitation, 1991
In the conversion of low temperature heat into electricity the greatest efficiency is obtained in many cases by using an organic Rankine cycle (ORC). This paper deals with an ORC-design, in which a high-speed oil free turbogenerator-feed pump is used.

Safety Aspects of Organic Rankine Cycles (ORC) with Combustible Working Fluids

, 2021
Trass i at organiske Rankine-syklusar (ORC) har eksistert ei stund, er det lite forsking på slike syklusar der subatmosfærisk trykk blir brukt. Subatmosfærisk trykk opnar for høgare trykkforhold som igjen gjev høgare verknadsgrad. Slike trykk er unngått då det er risiko for forbrenning dersom det trengjer luft frå omgjevnadane inn i systemet.
