Greenhouse gas 12,000 times worse than CO2 shows surprise rise in the atmosphere

A greenhouse gas that can cause 12,000 times more warming per tonne than carbon dioxide is rising unexpectedly in the atmosphere, despite reports by its major producers, China and India, that they've mostly eliminated emissions of the gas.

Atmospheric gas measurements at five stations around the world show that emissions of HFC-23 or trifluoromethane reached a record high in 2018 of 15,900 tonnes, reports a study led by Kieran Stanley, a visiting research fellow at the University of Bristol.

Newly developed screening processes will help accelerate carbon capture research

University of Alberta researchers have developed techniques that save a significant amount of time in developing more efficient carbon capture technologies, which may help lower the costs to use the technologies and increase their adoption as a way to mitigate carbon dioxide emissions.

U of A engineering professor Arvind Rajendran and his team developed a two-step screening process that assesses carbon capture materials called zeolites in seconds rather than a day.

IRS delay threatens carbon capture projects

WASHINGTON - Almost two years after Congress passed a law more than doubling tax credits for power and industrial plants that build systems to prevent carbon dioxide emissions, efforts to begin construction are on hold.

Companies have announced plans to build more than 20 so-called carbon capture facilities, but all are waiting for the Internal Revenue Service to issue guidance on the specifics of how the tax credit can be claimed.

US leads new wave of carbon capture and storage deployment

As we ring in the new decade, it has become ever more apparent that the next ten years will be crucial to leaping on decarbonization efforts. Time is not on our side. We cannot favor one technology over another. An all-of-the-above approach is necessary. Carbon capture and storage (CCS) technologies must be part of the portfolio of solutions to decrease emissions from energy-intensive sectors and existing infrastructure, as well as remove CO2 already present in the atmosphere.

Capturing CO2 from trucks and reducing their emissions by 90%

Researchers at EPFL have patented a new concept that could cut trucks’ CO2 emissions by almost 90%. It involves capturing CO2 within the exhaust system, converting it into a liquid and storing it on the vehicle. The liquid CO2 would then be delivered to a service station and where it will be turned back into fuel using renewable energy.

Electric vehicles are supposed to be green, but the truth is a bit murkier

At gatherings of electric vehicle enthusiasts, the curious surround Rob Spreitzer and his car. Both are celebrities in these circles — he's known as "High Mileage Rob," having driven more than 115,000 kilometres in his Tesla Model 3 in a little more than a year of ownership.

No other Model 3 in Canada is believed to have reached that milestone in such a short time, and it's possible no other battery-only electric vehicle has either.

Germany Pulls Plug On Wind Energy As Industry Suffers ‘Severe Crisis’

Once lavished with huge incentives, the German wind industry is being hit hard after the government recently ended the huge subsidies that were once aimed at expanding the installation of wind energy capacity.

Power grid operators had been struggling to keep the grid stable due to erratic feed-in and the subsidized feed-in of wind energy caused German electricity prices to become among the most expensive worldwide.
