Carbon capture
-
The oceans soak up enormous quantities of carbon dioxide, and MIT researchers say they've developed a way of releasing and capturing it that uses far less energy than direct air capture – with some other environmental benefits to boot.
-
Greenhouse gases and plastic waste are two of the biggest environmental problems the world faces today. A new reactor from Cambridge tackles both at once, converting CO2 and used plastic bottles into useful materials, powered entirely by sunlight.
-
Denmark is moving forward with Project Greensands, an initiative that will take huge quantities of captured carbon out to an oil rig in the North Sea, and pump it down to sequester it in the sandstone formations that once held oil and gas.
-
Although there are now a number of systems that capture carbon emissions from smokestacks, many people may still wonder – what is that captured carbon used for? Well, Swiss company On is making shoes out of the stuff.
-
The US state of Wyoming is set to welcome the world’s largest direct air capture plant for the removal of atmospheric carbon dioxide. Called Project Bison, the facility is expected to suck up five million tons of CO2 each year by 2030.
-
A student team has built a prototype electric passenger car that removes and stores carbon dioxide from the air as it rolls down the road, with the aim of capturing more CO2 than is emitted during the full lifecycle of the vehicle.
-
We're seeing a growing emphasis on direct air capture technology in our efforts to combat climate change, and an interesting new take on this technology could see it put to use on railways around the world.
-
Swiss outfit Climeworks has today broken ground on its second direct air capture plant in Iceland, and one that marks significant progress in its ambitions of removing gigatons of CO2 from the atmosphere each year by 2050.
-
Scientists have announced an interesting new means of removing carbon dioxide (CO2) from flue gas emissions, which would create a usable substance. It's a sheet of treated cotton, which converts CO2 gas into bicarbonate.
-
Carbon capture could be an important tool to fight climate change. Researchers have now developed a new compound that can reportedly remove carbon dioxide from ambient air with 99 percent efficiency and at least twice as fast as existing systems.
-
The US Department of Energy's efforts to combat climate change are set to receive a massive cash injection, with the Biden administration announcing US$3.5 billion in funding for regional direct air carbon capture hubs to help reach net-zero by 2050.
-
Engineers in the US and Mexico have developed a way to use soot from emissions to improve solar thermal devices. The coatings are not only cheaper to produce but more efficient than using materials like graphene, while reducing pollution.
