Researchers Say Mix of Policies and Current or Near-Term Technologies Could Phase Out US CO2 Emissions from Coal-Fired Power Plants by 2030

Green Car Congress

CO 2 emissions from US coal-fired power plant could be phased out entirely by 2030 using existing technologies or ones that could be commercially competitive with coal within about a decade, according to a paper published online 30 April in the ACS journal Environmental Science & Technology.

Process for Hydrogen Production from Sodium Sulfite Solutions Resulting from Capture of SO2 from Coal Flue Gas

Green Car Congress

A number of technologies have been employed for the capture and disposal of SO 2 from a flue gas stream. A typical example is the use of a dilute aqueous sodium hydroxide (NaOH) solution to absorb SO 2 from flue gas, forming an aqueous Na 2 SO 3 solution. Article ASAP doi: 10.1021/es903766w.

Lifecycle analysis finds Fischer-Tropsch diesel from coal and biomass with CCS can use less fossil energy than petroleum diesel, with GHG close to or below zero

Green Car Congress

A new study by Michael Wang and Jeongwoo Han at Argonne National Laboratory and Xiaomin Xie at Shanghai Jiao Tong University assesses the effects of carbon capture and storage (CCS) technology and cellulosic biomass and coal co-feeding in Fischer-Tropsch (FT) plants on energy use and greenhouse gas (GHG) emissions of FT diesel (FTD).

Are EVs Charged Mostly By Coal Power in the US?

EV Adoption

One of the common arguments you hear from people in America who are not fans of the idea of electric vehicles is that they are mostly charged from electricity produced from coal power plants. Heavy Coal Using States Accounted for Only 10% of EV Sales in 2020. The argument that EVs are powered mostly from coal simply isn’t true.

3 Oil Majors That Bet Big On Renewables

Green Car Congress

An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge.

Study finds co-producing FT fuels and electricity from coal and biomass with CCS delivers low GHG synfuels at lower cost and with less biomass than cellulosic ethanol

Green Car Congress

Furthermore, coproduction systems that utilize a co-feed of biomass and coal (CBTL) and incorporate CO 2 capture and storage (CCS) in the design offer attractive opportunities for decarbonizing both liquid fuels and power generation simultaneously.

Start-up Proposes Ionic Liquid - Amine Systems for Carbon Capture and Natural Gas Processing

Green Car Congress

The non-volatile nature and tunable chemistry of RTILs, when coupled with the high loading capacity of commodity amines, produce a “game-changing” technology for both CO 2 capture at fossil fuel-fired power plants and for natural gas processing, according to the company.
