Abstract: The present invention provides an energy storage device that utilizes a cold sink that undergoes cycles of freezing and thawing. The device converts electrical energy to stored thermal energy, and then re-converts the stored thermal energy to electrical energy, as needed or desired. The device can store energy on a large scale (e.g., on the order of megawatts or greater) and for an extended period of time (e.g., for at least 12 hours, or longer, as needed).

Abstract: The present invention provides energy and economically efficient and environmentally responsible processes for using acetone to dry, dehydrate and/or dewater various hydrated feedstocks.

Abstract: The present invention provides methods and systems for energetically efficient and economically viable temperature regulation of the environment within commercial scale enclosed microalgae cultivators.

Abstract: The present invention provides energetically and economically efficient methods for separating polyamide polymer(s) from commingled materials. The methods generally involve precipitating a polyamide polymer dissolved in a solvent (e.g., formic acid) using dimethyl ether (DME) as an antisolvent. The methods comprise dissolving the polyamide polymer in a solvent that (i) selectively dissolves the polyamide polymer relative to the other materials and (ii) has a higher solubility for DME relative to the polyamide polymer; and then contacting the mixture of the solvent with the dissolved polyamide polymer with DME, thereby precipitating the polyamide polymer.

Abstract: Systems and methods for improving dense gas solvent extraction of a solute and recovery of the solvent are provided. A pressure of the solvent/solute mixture obtained from an extraction chamber is increased, e.g. with a pump, thereby providing the mixture above saturation conditions. The increased pressure provides greater solubility of the solute and less solvent being vaporized in a heat exchanger. A buildup of solute in the system is reduced, thus improving system longevity. Also, process conditions of the separation process are isolated from those of the extraction process. Accordingly, the process conditions for the separating process are maintained while the process conditions of the extraction chamber vary with ambient temperature, thus saving cost and energy. This isolation also provides an ability to use, in the gas recovery cycle, a heat pump that can be used for many applications and environmental conditions while still using a conventional refrigerant.

Abstract: The present invention provides methods and systems for extracting ethanol from an ethanol-water solution comprising (1) extracting ethanol from an ethanol-water solution with a first solvent comprising an esterified fatty acid, wherein the esterified fatty acid comprises a hydroxylated fatty acid component and an alcohol component such that the alcohol component is a C3-6 alcohol, such that the distribution coefficient for ethanol in the mixture of the ethanol-water solution and the first solvent is at least 0.02 favoring the transfer of ethanol from the ethanol-water solution to the first solvent, thereby extracting the ethanol from the ethanol-water solution into the first solvent, and (2) extracting the ethanol-enriched first solvent with carbon dioxide, such that the carbon dioxide is at a liquid or near supercritical phase, wherein the distribution coefficient for ethanol in a mixture of the first solvent and the carbon dioxide is at least 0.
