Dispatchable capacity is declining as existing generation is retired and much of it is being replaced with intermittent renewable capacity. Approval of new fossil fuel generation is getting harder as the clean energy transition progresses. While short duration energy storage can cover many gaps in intermittent generation, periods of high demand and low renewable output can last multiple hours and days, beyond the economic duration of any battery storage technologies currently available. Presently this challenge is solved separately through accelerated development and market entry of the new long duration energy storages (LDES) and via evolution of the fleet of fully dispatchable, mainly gas-fired, power generators, along with NG/LNG chain facilities required for their operation. MADA uses another approach to solve the mentioned challenge: it integrates technological processes of its new LDES with operation of the co-located power generation plants and LNG production or regasification facilities, achieving a significant synergistic effect from such integration.
The known Liquid Air Energy Storage (LAES) technology distinguished by the freedom from the stubborn geographical, land, environmental, application and permission constraints has been selected by MADA for the required modernization and target integration with the co-located plants and facilities. A general idea of this technology can be had from viewing the MOVIE presented below.
In the LAES version modernized by MADA and called as Integrated LAES (I-LAES) the processes of internal recovery of the waste heat and cold streams have been replaced by an exchange of the waste energy streams between the I-LAES and co-located power generation or LNG production / regasification facilities. As is shown in the diagram below, the waste thermal energy obtained by the L-LAES from the co-located facilities are profitably used to reduce consumption of charge power during charge cycle or/and increase storage power output during discharge cycle, and so enhance the I-LAES round-trip efficiency (RTE). In its turn, the waste thermal energy supplied by the I-LAES to the co-located facilities during charge and/or discharge cycles helps to significantly improve the performance of the co-located facilities: increase their power output or production yield, enhance fuel efficiency and reduce or even make zero their carbon emissions.

In so-called LAGT configuration the deployment of MADA’s I-LAES technology at the peaking gas turbine (GT) plant makes possible to use a high-grade cold energy of discharged liquid air evaporation to provide operation of turbine inlet air chilling (TIAC) and recycled cold air compressing (RCAC) systems. Simultaneously, a high-grade heat energy of the GT exhaust is used to superheat the evaporated air before its expansion at the LAES.
Utilizing the MADA’s I-LAES technology at the peaking gas engine (GE) plant in so-called LAGE configuration may provide the use of a high-grade cold energy of discharged liquid air evaporation for cryogenic capture of CO2 emissions from GE exhaust and the recovery of LAES exhausted air as combustion air for the GE. Simultaneously, a high-grade heat energy of the GT exhaust is used to superheat the evaporated air before its expansion at the LAES
As an unique instrument for deployment in the today’s transition to the decarbonized electric grids and net zero carbon footprint of power generation, MADA is offering its new proprietary I-LAES technology. It is only sole of all known LDES technologies that provides decarbonization of the electric grids not only through storage and return to the grids an excess of renewable energy, but through cryogenic post-combustion 100% capture and removal of CO2 emissions from exhaust of gas and liquid fuel-fired co-located power generators as well. This functional innovation of I-LAES technology may be inherent in all MADA’s technological products, wherein LAES is integrated with gas engines, diesel engines or gas turbines
