Active Energy plc (LON:AEG, OTCQB:ATGVF), the international biomass based renewable energy business, has announcd it has been awarded a further patent from the US Patent and Trademark Office with respect to the Company’s proprietary technology for process for beneficiating and cleaning biomass (US Patent No. 11,702,607).
The patent awards Active Energy with the rights to exclude others from making, using, and selling any apparatus or system that includes the Company’s existing CoalSwitch existing production technology.
Active Energy’s patented system includes a reaction vessel that increases exposure of biomass within the reaction vessel to steam. This latest-issued patent complements earlier patents that Active Energy has been granted for its CoalSwitch® production technology.
CoalSwitch® has been shown to reduce lifecycle CO2 emissions by up to 99 per cent. compared to coal and up to 97 per cent. compared to natural gas in an independent report from Life Cycle Associates. This is in addition to independent testing completed under the Sustainable Transportation and Energy Program (“STEP”) that has shown that CoalSwitch®, can readily co-fire with coal without significant additional capital expenditure and in doing so significantly reduces emissions and produces fewer pollutants.
Barron Hewetson, Chief Technology Officer of Active Energy Group, commented: “The award of this patent builds upon the original patent and increases Active Energy’s ability to control the resulting fixed carbon content of the finished product. To simplify, our steam explosion unlocks pathways that weren’t previously economically viable, and we are now able to strategically target industries and commercial sectors that were previously not available. We are expanding upon the “steam explosion” process and capitalizing on the inherent synergy of other waste biomass and waste wood production systems in novel ways to drive future growth, notably in pre-treatment systems and alternate thermo treatment systems, including pyrolysis.”
