Wikipedia notes that "in some geographic localities, photovoltaic solar or onshore wind is the cheapest new-build electricity," a sign of just how mature those particular technologies have become. Browsing by maturity separates technologies still emerging from those already fully commercial.FactsTRL 9: Actual System Proven in Operational EnvironmentSourcesComments (0)Reader Challenges (0)FactsComparisonEra of EmergenceWell-attested1931 1TRL 9: Actual System Proven in Operational EnvironmentFilter Results31 entriesTechnology TypeAllAir Purification (3)Carbon Capture (2)Gas Detection and Vapor Recovery (4)Nitrogen Oxide and Vehicle Exhaust Control (5)Particulate Control Devices (6)Scrubbers and Flue Gas Cleaning (6)Energy Source UsedAllNatural Gas (1)Invented EraAll1870 (1)1895 (1)1907 (1)1927 (1)1930 (1)1931 (1)1956 (2)1957 (1)1961 (1)1973 (1)1975 (1)1990 (1)Show ResultsBrowseCompareSelect all 31Activated Carbon InjectionTRL 9: Actual System Proven in Operational EnvironmentAir FilterTRL 9: Actual System Proven in Operational EnvironmentAir PurifierTRL 9: Actual System Proven in Operational EnvironmentAir SeparationTRL 9: Actual System Proven in Operational EnvironmentAmine Gas TreatingTRL 9: Actual System Proven in Operational EnvironmentBaghouseTRL 9: Actual System Proven in Operational EnvironmentCarbon Dioxide ScrubberTRL 9: Actual System Proven in Operational EnvironmentCarbon FilteringTRL 9: Actual System Proven in Operational EnvironmentCatalytic ConverterTRL 9: Actual System Proven in Operational EnvironmentContinuous Emissions Monitoring SystemTRL 9: Actual System Proven in Operational EnvironmentCrankcase Ventilation SystemTRL 9: Actual System Proven in Operational EnvironmentCyclonic SeparationTRL 9: Actual System Proven in Operational EnvironmentDiesel Particulate FilterTRL 9: Actual System Proven in Operational EnvironmentDry ScrubberTRL 9: Actual System Proven in Operational EnvironmentElectrochemical Reduction of Carbon DioxideTRL 9: Actual System Proven in Operational EnvironmentElectrostatic PrecipitatorTRL 9: Actual System Proven in Operational EnvironmentExhaust Gas RecirculationTRL 9: Actual System Proven in Operational EnvironmentExplosimeterTRL 9: Actual System Proven in Operational EnvironmentFabric FilterTRL 9: Actual System Proven in Operational EnvironmentFLOX (Flameless Oxidation)TRL 9: Actual System Proven in Operational EnvironmentFlue GasTRL 9: Actual System Proven in Operational EnvironmentFlue-Gas DesulfurizationTRL 9: Actual System Proven in Operational EnvironmentGas DetectorTRL 9: Actual System Proven in Operational EnvironmentGas FlareTRL 9: Actual System Proven in Operational EnvironmentLow-NOx BurnerTRL 9: Actual System Proven in Operational EnvironmentRegenerative Thermal OxidizerTRL 9: Actual System Proven in Operational EnvironmentSelective Catalytic ReductionTRL 9: Actual System Proven in Operational EnvironmentSelective Non-Catalytic ReductionTRL 9: Actual System Proven in Operational EnvironmentVapor Recovery UnitTRL 9: Actual System Proven in Operational EnvironmentVenturi ScrubberTRL 9: Actual System Proven in Operational EnvironmentWet ScrubberTRL 9: Actual System Proven in Operational EnvironmentSources1.
