A research team from the Georgia Institute of Technology in Atlanta have developed a new kind of material called hyperbranched aminosilica (HAS), in which the amine is held on a solid porous silica substrate, on the tips of several branches.
An advantage of HAS is the ability to reuse it many times (tested 12 times) without losing its absorption capacity. But the best thing about this technology is the low energy input compared to the liquid amines, which must be heated at very high temperatures. The solid amines HAS have to be heated to just 110°C to release the CO₂, which means a 75% lower energy consumption than for liquid amines.
However, a remaining challenge is the need to reduce the heating effect of the amine/CO₂ reaction because HAS captures best at cool temperatures.
The research team points to the reuse of the captured CO₂ to feed biofuel stock. A biofuel producer in Louisiana precisely uses captured CO₂ to grow algae.
For now, the reasearcher Christopher Jones is working on a pilot air capture plant in Menlo Park in California, with the aim to absorb 2 tons of CO₂ per day.

Recent attacks on Ukraine’s Zaporizhzhia nuclear power plant "mark the beginning of a new and gravely dangerous front of the war," the UN atomic agency's director general said last week.
After years of inaction, Germany is working on its Carbon Management Strategy to resolve how CCS can play a role in climate action in industry. At the end of February, the Federal Ministry for Economic Affairs and Climate Action published first key points and a proposal to amend the law Kohlenstoffdioxid Speicherungsgesetz (KSpG). Bellona Deutschland, who was actively involved in the previous stakeholder dialogue submitted a statement in the association hearing.
In the midst of a global discussion on whether natural gas should be used as a transitional fuel and whether emissions from its extraction, production, transport and use are significantly less than those from other fossil fuels, Russia has developed ambitious plans to increase its own production of liquified natural gas (LNG) in the Arctic – a region with 75% of proven gas reserves in Russia – to raise its share in the international gas trade.
In this news digest, we monitor events that impact the environment in the Russian Arctic. Our main focus lies in identifying the factors that contribute to pollution risks and climate change.
