„Carbon Capture and Storage (CCS) is a process wherein up to 90% of carbon dioxide emissions produced as a result of combustion of fossil fuels, are captured. Thus, preventing them from entering the atmosphere. The process comprises three steps, first step involves capturing the carbon dioxide which is emitted, second step involves transportation of the captured carbon dioxide and the third step involves its secure storage.“
„Carbon capture and storage (CCS) works by catching CO2 produced by large industry (think steel factories or oil refineries) before it goes into the atmosphere, transporting it and then using high pressure to funnel it deep into the ground.“
„Britain could have the world’s first “carbon-negative” power station by the mid-2020s under plans by a trio of energy companies to capture carbon emissions in the Humber region.“
„Scientists have developed a new way of achieving artificial photosynthesis, producing high-energy hydrocarbons by leveraging electron-rich gold nanoparticles as a catalyst.“

„A Canadian startup plans to build the largest carbon dioxide removal plant in the world, capable of sucking half a million metric tons of the greenhouse gas out of the air every year. If the project is ultimately built, it will represent a big step forward for direct air capture, a technology that a growing number of studies find could be essential for preventing dangerous levels of global warming. But it comes with a catch.„

„This review provides new insights into the state-of-the-art accomplishments in the utilization of biochar in environmental management and covers three perspectives: firstly, mitigation of greenhouse gas (GHG) emissions, such as sequestration of CO2 and CH4 in global carbon pools and mitigation of N2O emissions; secondly, pollution control, including adsorptive removal and reactive removal of inorganic and organic contaminants; thirdly, potential negative aspects of biochar applications, including contaminations originated from biochar, negative alterations to soil properties and soil biota, negative impacts of biochar on GHG emissions and negative impacts of biochar migration.“

„Converting carbon dioxide (CO2) into liquid fuels and synthesis gas is a world-wide priority. But there is no experimental information on the initial atomic level events for CO2 electroreduction on the metal catalysts to provide the basis for developing improved catalysts. Here we combine ambient pressure X-ray photoelectron spectroscopy with quantum mechanics to examine the processes as Ag is exposed to CO2 both alone and in the presence of H2O at 298 K.“
