“…We introduced a correction factor, ηcorrection, for the oil injection flow. A small deviation from the air flow rate Ṁ induces a significant error in the difference of heat exchanged with the oil ∆ calculated in equation (7). The air mass flow Ṁ depends on the Reynolds number air flow measured with the orifice plate in the diaphragm.…”

“…A CAES power generation facility uses electric motor-driven compressors to inject air into a reservoir, later releasing the compressed air to turn turbines and generate electricity into the grid. Even though CAES concept dates back more than four decades ago [3], environmental concerns and technological advances are encouraging their research and development interest to increase worldwide [4][5][6][7].…”

Compressed air energy storage facility with water tank for thermal recovery

et al. 2020

The paper presents the prototype of the first Romanian Compressed Air Energy Storage (CAES) installation. The relatively small scale facility consists of a twin-screw compressor, driven by a 110 kW threephase asynchronous motor, which supplies pressurized air into a 50m3 reservoir, of 20 bar maximum pressure. The air from the vessel is released into a twin-screw expander, whose shaft spins a 132 kW electric generator. The demonstrative model makes use of a 5m3 water tank acting as heat transfer unit, for minimising losses and increasing efficiency and the electric power generated. Air compression and decompression induce energy losses, resulting in a low efficiency, mainly caused by air heating during compression, waste heat being released into the atmosphere. A similar problem is air cooling during decompression, lowering the electric power generated. Thus, using a thermal storage unit plays an essential role in the proper functioning of the facility and in generating maximum electric power. Supervisory control and data acquisition is performed from the automation cabinets. During commissioning tests, a constant stable power of around 50 kW with an 80 kW peak was recorded.

“…To our knowledge, no grid-scale AA-CAES is presently available. Dib et al worked on a system composed of commercial units that are available on the market [14]. By means of simulation, they found a system efficiency of 33.7%, a Levelised Cost Of Energy (LCOE) as low as 0.25 €/kWh and that the storage pressure had the biggest impact on the total cost.…”

The urgent energy transition needs a better penetration of renewable energy in the world’s energy mix. The intermittency of renewables requires the use of longer-term storage. The present system uses water displacement, in a lined rock cavern or in an aerial pressurised vessel, as the virtual piston of compressor and expander functions in a carbon dioxide heat pump cycle (HPC) and in an organic transcritical cycle (OTC). Within an impermeable membrane, carbon dioxide is compressed and expanded by filling and emptying pumped-hydro water. Carbon dioxide exchanges heat with two atmospheric thermal storage pits. The hot fluid and ice pits are charged by the HPC when renewable energy becomes available and discharged by the OTC when electricity is needed. A numerical model was built to replicate the system’s losses and to calculate its round-trip efficiency (RTE). A subsequent parametric study highlights key parameters for sizing and optimisation. With an expected RTE of around 70%, this CO2 PHES (pumped-hydro electricity storage) coupled with PTES (pumped thermal energy storage) could become a game-changer by allowing the efficient storage of intermittent renewable energy and by integrating with district heating and cooling networks, as required by cities and industry in the future.

“…When such cavities are not available, high pressure vessels are necessary to reduce the storage volume. Dib et al [6] demonstrated that increasing the storage pressure from 40 to 200 bar greatly reduce the initial cost of the system. However, turbines cannot use air at a so high pressure.…”

A trigenerative compressed air energy storage system (CAES) integrating vortex tubes is investigated numerically. In this work, the system is sized according to the electrical power required for the community of Aupaluk in Nunavik (QC). The vortex tube parameters are optimized using a genetic algorithm to maximize the electrical efficiency of the system and the reduction in carbon dioxide emissions. The proposed system increases both the electrical efficiency and the reduction in carbon dioxide emissions when compared to the same system using a throttling valve in the discharging process. Details on the pressure and temperature levels at each step of the system are provided for the optimal solution. Finally, vortex tubes may generate liquid carbon dioxide from atmospheric air in CAES using high storage pressure. This new quadrigeneration CAES is one promising way to address the problem of climate change.Index Terms-Compressed-air energy storage system, Ranque-Hilsch vortex tube, thermodynamic model, multiobjective optimization.
