Solar energy is a renewable energy of high importance and a further boost of utilization is crucial towards de-fossilizing the continually increasing energy demand and mitigating global warming. Solar energy is capable to satisfy effectively both electricity and thermal energy needs while a wide range of technologies is available covering different temperature ranges and systems’ sizes, to collect and convert heat to power. The use of low temperature solar heat to power generation is however a challenging and hot research issue, since it incorporates low heat to power conversion efficiency and a questionable cost-effectiveness.
The current state of the art indicates that the Organic Rankine Cycle (ORC) technology is almost exclusively used to convert low grade solar heat to electricity, due to its higher conversion efficiency and maturity, compared to all alternative technical solutions. However, several promising ideas towards improving further the thermal efficiency are under investigation such as expander liquid-flooding, supercritical operation, new organic fluids or TFC. Thermal efficiency improvement is a key challenge to enhance technical and economic attractiveness of low-grade solar heat-to-power conversion.
This Special Issue aims to further contribute in the efficient conversion of low temperature solar heat to electricity through the well-known technology of ORC. In this context, advances of all relevant technologies, design and control techniques and solutions are in the spotlight of this issue.
