“…The underground pumped hydro storage (UPHS) technology is a well-established energy storage system. Following the principle of UPHS, Olsen et al (2015) introduced a novel concept of using a membrane to store the water which is named as Underground Pumped Hydro Storage Membrane (UPHSM). The energy is stored by elevating a mass of dart or soil through water being pumped into a below-ground readily constructed cavity.…”

“…The important feature of this concept is the fairly price efficient design where the main cost component is required for movement of the soil. The cost analysis indicated that a full-scale system will be economically viable when associated to the remote area power grid where the income can be generated by providing the daily power demand as well as marketing ancillary services, (Olsen et al 2015). Figure 2 It is assumed that the hydrostatic pressure in the membrane cavity, hydrodynamic losses, and the possible effects of energy stored in the soil edge zone are negligible.…”

“…Figure 2 It is assumed that the hydrostatic pressure in the membrane cavity, hydrodynamic losses, and the possible effects of energy stored in the soil edge zone are negligible. Therefore, the total stored energy (E) assuming the square dimensions of a square membrane cavity (length = width = L) can be calculated by the formula given in Equation 2 In addition to the above technological details, Olsen et al (2015) provided the values of design parameters at three experiment levels including lab test, field test, and full scale plant as given in…”

Worldwide, off-grid remote areas are facing energy issues. The Canadian remote communities depend on diesel generation posing many issues including high fuel cost and greenhouse gas emissions. The government policy is to connect such communities to electricity grid that requires high cost and long time. In this situation renewable generators, including wind and solar, may be an appropriate solution. However, their intermittent nature is problematic that needs to be addressed. Therefore, this project investigated the integration of underground pumped hydro storage membrane system (UPHSM) to address the intermittency to provide steady and reliable power supply. A four step systematic methodology is proposed to examine the feasibility of UPHSM in a remote community. The case study results show an overall 64 percent reduction in diesel consumption and 295696 t in CO2 emission. The study results also confirmed that the proposed system is a viable solution for off-grid remote areas.

“…Pumps used in UPHES systems have higher efficiency than conventional PES systems. Olsen et al 25 have presented a novel principle for UPHES that is storing energy by elevating a mass of soil through the pumping of water into an underground cavity. They have emphasized that the proposed concept has a lower cost than classical UPHES.…”

This study develops a geothermal-based underground pumped hydroenergy storage system (UPHES) integrated with an organic Rankine cycle (ORC) and district heating. The ORC has been integrated into the system for contributing the power demand of the pump used during the charging period to pump the water from the underground to the upper reservoir. District heating has been performed by geothermal. Heat recovered from the ORC has been used for the preheating of water used in district heating before entering the upper reservoir. With this proposed integrated system, both the peak energy demand has been shifted to off-peak hours and district heating has been performed. An ORC has also been included in the system to contribute to the energy demand of the UPHES pump. In order to evaluate the system's performance, thermodynamic analysis has been performed base on energetic and exergetic efficiencies. In the base case study, 60 MWh of electricity has stored by the UPHES. Also, a 2.8 MW of heating demand of 100 houses has been met and a 1.7 MW of power has been generated by the ORC. The power of the UPHES pump has been calculated as 6.81 MW. The efficiency of the UPHES system is 73.34%. Overall energy and exergy efficiencies of the proposed integrated system have been calculated as 93.09% and 78.37%, respectively.

Intermittency characteristic of renewable energy sources can be resolved using an energy storage technology. The function of the energy storage system is to store the excess energy that is produced from various renewable energy sources during the off‐peak hours and releases the same energy during the peak hours. The energy that is produced from the renewable energy sources can be stored in different forms such as Mechanical, Electrical, Electrochemical, Thermal, Chemical energy etc. Among all these forms of stored energy, a CAES technology under the Mechanical form of energy is the most cost effective for the bulk energy storage purpose. It involves a combined operation of various components such as Compressor/Expander, Gas turbine, combustion chambers, heat exchangers, generator unit, and underground compressed air storage. This article focuses to review the detail of various CAES systems such as D‐CAES, A‐CAES, I‐CAES etc. Additionally, it presents various technologies that are used to improve the energy efficiency and applicability of the CAES system. It is found that a maximum RTE of the C‐CAES, A‐CAES, and I‐CAES are 54%, 71%, and 80%, respectively. In addition, the RTE of the modified CAES systems such as LP‐CAES, PH‐CAES, and SC‐CAES are about 90%, 80%, and 60 to 80%, respectively.
