Newport Beach, CA, January 03, 2018 --(PR.com
)-- A new patent has been filed by Stored Air Power, Inc. (SAP) for an all-in-one adiabatic air energy storage system (AESS) which combines a dual compressor/expander coupled to a motor/generator to an insulated gunite storage tank. This innovative storage system sets a new paradigm that improves the applicability for on-site distributed energy, increases efficiency to 70% instead of 40% for other compressed air energy storage (CAES) systems and lowers cost of previous adiabatic air storage systems. The AESS can be used to produce power from 500kW to 250MW at a cost lower than any available system.
· Energy Savings up to 25% – Time of use, demand response & demand charges
· Level Out Fluxuations in renewable power generation (like wind and solar)
· Standby Power for power interruptions, national defense & disasters
· No Capital Outlay with Discount Power Agreement
The race is on to create more efficient and economical ways to store energy and beat the cost of peak-power charges and blackouts. Energy storage systems provide a wide array of technological approaches to managing our power supply in order to create a more secure and resilient energy infrastructure and bring cost savings to consumers. There are long lists of old and new storage ideas like lead acid batteries, solid state batteries, other batteries, thermal, flywheels, pumped hydro-power and CAES. SAP has come up with a method of combining the most efficient, low-cost technologies together with the most efficient, low-cost storage solutions with their Adiabatic Air Energy Storage SystemTM (AESS). When there is a need for low-cost energy use during peak hours or emergency energy, their AESS turns the stored compressed air into clean, distributed electricity.
The AESS stores energy by compressing air or gas at low-peak times and sends it to an insulated gunite storage vessel to store the pressure and heat from compression and then returns the hot air/gas back through the expander generator in reverse to generate electricity to supplement renewable power or for use during peak hours, national defense and natural disasters. A site-constructed air storage vessel will serve as a heat sink constructed of post tension cables, spherically-shaped gunite concrete capable of withstanding pressures up to 1000 PSI. It is insulated to retain the heat of compression to be used to offset the Joule-Thomson cooling effect from the expansion of air during power generation. This system sets a new paradigm for CAES that improves the applicability for on-site distributed energy, doesn’t use fossil fuel to preheat the air on expansion, increases efficiency and lowers cost of previous adiabatic air storage systems.
The significant difference between peak and off-peak prices of electricity has created the incentive to improve energy storage technologies. Electric utilities often apply energy storage methods to meet fluxuations in the power load demand for solar and wind generation. According to the US Energy Information Administration (EIA), 2017 average peak power can be as high as $144.39/MWh compared to the lowest average peak power cost of only $0.14/MWh.(1)
