Summary Albeit numerous studies discussing manifold issues of combined cooling, heating and power (CCHP) systems, there is still lack of theoretical studies indicating to what extent the energy mismatch and the deviating working conditions affect the CCHP performance, absence of reports systematically summarizing the multiple effects of energy saving units (ESUs), and deficiency of research quantifying the benefits from ESUs to energy savings. The shortage of such studies will confuse some CCHP designers when a CCHP system is designed. Therefore, in this research, theoretical discussions have been undertaken about the energy mismatch issue between CCHP systems and their users as well as the multiple effects of ESUs on CCHP systems. An improved calculational method of energy storage rate (ESR) has been adopted to evaluate the energy savings performance of CCHP systems. Two general heat‐to‐electricity ratios (Ruser for CCHP users and RCCHP for CCHP systems) have been used to quantify the energy mismatch between CCHP systems and their users. In the regime of ‘priority of providing cooling’, the ESR reaches its maximum when Ruser is equal to RCCHP. Otherwise, the ESR tends to decrease rapidly, especially when the electrical demand must be supplemented from the grid. Furthermore, when the CCHP system produces more electricity than required, the payment mode of extra electricity from the CCHP system will significantly affect the ESR. Therefore, it is imperative to reach an international consensus regarding the dispose of extra CCHP products. The theoretical analyses also corroborate the advantages of incorporating an ESU into a CCHP system. The ESU enables the CCHP system components to operate at their optimal working conditions. Meanwhile, the power generation unit and the absorption refrigerator capacities can then be reduced. Moreover, the ESU also promotes the productivity of electricity and ensures an undiminished ESR regardless of what extra electricity payment mode is adopted. Copyright © 2016 John Wiley & Sons, Ltd.

“…Energy is retrieved by expanding the compressed air through a turbine to produce electricity. According to Zhai et al (2013), CAES are reliable, have negligible self-discharge, are non-toxic, and have very long lifetimes. One disadvantage of CAES is that it has a low thermodynamic efficiency because there is a rise in temperature of the air during compression, which causes heat to be lost to the surroundings.…”

This paper recommends research that is required to develop and, thus, enable cost effective, residential electricity storage systems for renewable energy. As residential electricity generation from renewable sources becomes more prevalent, residential energy storage will become an important factor in ensuring the stability of the electrical grid; grid operators will be able to timeshift demand to smooth peaks and match supply capacity. However, local storage of excess energy from renewable sources is currently not economically attractive due to the long payback period required to recover capital costs. NIST Engineering Laboratory is well positioned to make significant contributions to the relatively neglected field of residential energy storage. Possession of the NIST's Net-Zero Energy Residential Test Facility makes it possible to work collaboratively with other laboratories within NIST to demonstrate field performance of new ideas in energy storage technologies such as batteries, super capacitors, superconducting magnets, and hydrogen storage. In addition, EL staff and facilities are well matched to projects in Phase Change Material (PCM) facades and PCM evaporators, pumped hydro, solar water heaters and cost/benefit analyses. Potential project ideas are provided for these areas of research.1 Corresponding author. Tel./fax: (301) 975-5282/(301) 975-8973.
