Newly built (greenfield) power plant offer the advantage of optimised integration measures to reduce the efficiency penalty associated with the application of a post-combustion CO2 capture process by wet chemical absorption. Especially, the integration of waste heat from the desorber overhead condenser of the CO2 capture unit (CCU) and from the CO2 compressor into the [...]

Carter explained that the substance became known as “dry water” because it consists of 95 percent water and yet is a dry powder. Each powder particle contains a water droplet surrounded by modified silica, the stuff that makes up ordinary beach sand. The silica coating prevents the water droplets from combining and turning back into [...]

Hollow fiber sorbents in rapid thermal swing mode, packed bed solid sorbents in thermal swing mode, hollow fiber membranes, monoethanolamine-based liquid amines, and chilled ammonia CO2 sorption systems are compared on an energetic basis for CO2 capture from coal-fired power plants. The systems are compared on an intrinsic heat and auxiliary basis both with and [...]

Abstract: The present invention relates to methods for the production of isoprene by the direct conversion of atmospheric carbon dioxide using metabolically engineered genetically engineered photosynthetic microorganisms. The present invention also relates to genetically engineered photosynthetic microorganisms, such as cyanobacteria, that are capable of producing isoprene from CO2.Read the app.In English: This app is cool [...]

The original FutureGen site was supposed to be in Matoon, Illinois, and serve as the nation’s first commercial-scale coal plant equipped with carbon capture and sequestration (CCS) technology. Under the revised FutureGen 2.0 plan, the site will now serve as a regional deep saline injection CO2 storage facility.  Instead, an idle 200 megawatt coal-fired power [...]

This study aimed to achieve higher CO2 consumption ability and lipid productivity of an indigenous microalgal isolate Scenedesmus obliquus CNW-N by a two-stage cultivation strategy. The microalga strain was first cultivated with 10% CO2 using a nutrient-rich medium to promote cell growth, which was followed by a nutrient-deficient condition to trigger lipid accumulation. The optimal [...]

Using the catalyst technology, Novomer can form both high molecular weight (MW) polymers to make thermoplastic polymers that can be used to make plastics, and low MW polymers that can be used to make resins for use as coatings and adhesives. The technology can also be used to convert carbon monoxide into a range of [...]
