Scheme 1 liquid nitrogen energy storage plant layout. At the peak times, the stored LN2 is used to drive the recovery cycle where LN2 is pumped to a heat exchanger (HX4) to extract its coldness which stores in cold storage system to reuse in liquefaction plant mode while LN2 evaporates and superheats.
The NNPS recovers nitrogen pressure energy for power generation and uses post-expansion cold energy to further reduce feedstock nitrogen temperature and compression energy consumption. We selected an NPS in China as a case study to analyze the performance of the NNPS under various operating conditions through energy, exergy, and economic analysis.
Currently, the large-scale energy storage plants with a storage capacity of 100 MWh used worldwide are Pumped Storage Hydropower (PSH) and Compressed Air Energy Storage (CAES) (Hameer and Niekerk, 2015).
We propose a novel nitrogen piping system (NNPS) and determine the key technical parameters to recover the pressure energy. The NNPS recovers nitrogen pressure energy for power generation and uses post-expansion cold energy to further reduce feedstock nitrogen temperature and compression energy consumption.
In NPS, the exergy loss of nitrogen is as high as 3594.29 kW after TV1 and TV2. The exergy loss is reduced to 2309.16, 1533.93, and 640.60 kW, and the system exergy efficiency is improved to 0.56, 0.61, and 0.66, respectively, in cases 1–3 in NNPS. Fig. 10. Diagram of the exergy flow in the system (kW).
