With the increase of power generation from renewable energy sources and due to their intermittent nature, the power grid is facing the great challenge in maintaining the power network stability and reliability. To address the challenge, one of the options is to detach the power generation from consumption via energy storage. The intention of this paper is to give an overview of the current technology developments in compressed air energy storage (CAES) and the future direction of the technology development in this area. Compared with other energy storage technologies, CAES is proven to be a clean and sustainable type of energy storage with the unique features of high capacity and long-duration of the storage. Its scale and cost are similar to pumped hydroelectric storage (PHS), thus CAES has attracted much attention in recent years while further development for PHS is restricted by the availability of suitable geological locations. The paper presents the state-of-the-art of current CAES technology development, analyses the major technological barriers/weaknesses and proposes suggestions for future technology development. This paper should provide a useful reference for CAES technology research and development strategy.

“…The compressed gas expands through three phases: charging, expansion and discharging. In this process, the compressed gas pushes the expander center and side chambers getting bigger in each cycle; the expanding crescent sealed side chambers immediately open at some moment in each cycle and they do not exist anymore during the rest of each cycle; the moving scroll does not rotate but rather wobbles on a cam which connects to the expander shaft; the overall generalized motion from the moving scroll movement is the rotation of the shaft (for details, refer to [25,26] The paper starts with the mathematical modelling of the dynamic process of the proposed recycling scheme as shown in Figure 1. The measured operation data (pressure, flow rate and temperature) from a gasoline engine discharge port is used to compare and examine the working conditions of the scroll expander for the exhaust energy recovery application.…”

Abstract:The growing number of vehicles on the road has led to a rapid increase in fuel consumption and toxic gas emissions, so the challenges in fuel efficiency improvement and reduction of CO 2 and NO x emissions have always been on the top agenda of the automotive industry. The paper presents a feasibility study of recovering the low-pressure exhaust gas energy via by-pass connection of a scroll expander to the engine system exhaust. The paper starts with the description of the proposed new exhaust energy recycling scheme and the mathematical modelling of the system. A feasibility study is carried out to investigate whether this new scheme can work with the engine operation conditions specified by the engine test data. The initial study indicated that the scroll expander structure needs to be modified; otherwise, it cannot be used for exhaust energy recovery. The experimental test and simulation results presented in this paper indicate that it is feasible to recover the low-pressure exhaust gas energy using a scroll expander with a modified structure. The proposed energy recovery system has the potential to produce over 400 W power output with over 90% of engine exhaust flow recycling.
