MADA's Integrated LAES
Existing gas-fired generating and liquid natural gas (LNG) facilities are still needed to provide energy for the global economy and will likely be needed for many decades. Although cleaner than coal, gas-fired power generation and the production and use of LNG still generate massive amounts of greenhouse gas (GHG) emissions. Renewables can reduce emissions by reducing the use of gas for power generation, but currently gas is the most economic form of fully dispatchable power that is needed for reliable power grids. Solutions are needed to reduce the emissions and improve the performance of LNG production/regasification and gas-fired power generation as the clean energy transition continues.
Integrated LAES – Reducing the Emissions and Improving the Performance of Today’s Gas Technologies
MADA’s Liquid Air Energy Storage (LAES) technology takes advantage of sources of waste heat and cold from gas turbines, LNG facilities and industrial processes, as well as excess renewable power on the grid to increase the efficiency of these technologies, store the energy for later use by the host facility or the grid and increase output beyond the host facility’s capacity during periods of greatest demand.
MADA’s novel, proprietary Integrated Liquid Air Energy Storage for use with gas turbines or engines (LAGT) integrates liquid air energy storage into the operations of existing (or new) gas-fired power plants. This has the benefit of providing a high quality heat source from the gas turbine/engine waste heat to superheat the liquid air during discharge, driving significantly higher round trip efficiency for the LAES, while at the same time taking advantage of the waste cold of the discharging liquid air to eliminate CO2 emissions from the power plant exhaust and, specifically for gas turbines, to cool the air entering the gas turbine, increasing the output and efficiency of the gas turbine.
MADA’s Turbine Inlet Air Chilling (TIAC) when integrated with gas turbines, increases the fuel efficiency and peak output for the unit at ambient temperatures above 60°F, with exponential improvements in performance as ambient temperatures increase.
The deployment of MADA’s LAES technology at LNG production plants increases the yield and efficiency of the LNG plant by capturing the LAES cold energy. Using the waste heat from the LNG production process helps regasify and superheat air at the LAES to generate discharged power, and increase its round trip efficiency.
Utilizing MADA’s LAES technology at LNG regasification plants improves the efficiency of LAES storage efficiency by using the cold LNG to help liquefy air, while the waste heat from air compression is used to regasify the LNG. When combined with an onsite gas-fired reciprocating engine, the regasification process is further enhanced by utilizing the engine’s waste heat.
Liquid Air Energy Flow Process
MADA has patented a novel, proprietary Integrated Liquid Air Energy Storage with Carbon Capture for Gas Turbines/Engines (LAGT) which integrates with simple cycle gas turbines (GTs) or reciprocating gas engines (GEs). Our technology utilizes the temperature difference between liquid air (-320°F) and solid CO2 (-109°F) to capture 99-100% of the carbon emissions from GT and GE peakers, regardless of their fuel, while providing long duration energy storage.
Foundational LAES IP
The MADA Analytics foundational LAES IP for long-duration energy storage and dispatchable generation is based on approved U.S. patents from key personnel.
