Solar Panels Are Starting to Die, Leaving Behind Toxic Trash

Solar panels are an increasingly important source of renewable power that will play an essential role in fighting climate change. They are also complex pieces of technology that become big, bulky sheets of electronic waste at the end of their lives—and right now, most of the world doesn’t have a plan for dealing with that.

But we’ll need to develop one soon, because the solar e-waste glut is coming.

Argonne National Lab Breakthrough Turns Carbon Dioxide Into Ethanol

According to a press release from ANL, researchers at the lab, working with partners at Northern Illinois University, have discovered a new electrocatalyst that converts carbon dioxide and water into ethanol with very high energy efficiency, high selectivity for the desired final product, and low cost. Ethanol is a particularly desirable commodity because it is an ingredient in nearly all US gasoline and is widely used as an intermediate product in the chemical, pharmaceutical, and cosmetics industries.

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.

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.

NEWS Selective graphene membranes could invigorate carbon capture technology

Scientists have developed membranes that separate carbon dioxide from nitrogen. The membranes feature porous graphene decorated with polymers and use interactions between the polymers and carbon dioxide to create a system that can selectively filter carbon dioxide out of flue gas.

Carbon capture and storage remains one of the most promising strategies to limit the impact of carbon emissions. Some industrial plants already capture carbon dioxide using amine sorbents, where heating regenerates the amines and removes the carbon dioxide – but this process is energy intensive.
