The newly published article focuses on the physical & chemical aspects of #CO2#storage via liquid & solid chemical carriers & sorbents & gives an overview of the energetics around their use & options for their future development. #CarbonRemoval #CarbonStorage
🧵 1/7
Research pointed that "exciting opportunities for coupling #capture and medium to high maturity multi-year #storage technologies could support #CarbonRemoval in the coming decades." 2/7
Highlights of the analysis are:
🔸"The remarkable #storage capacity of oxalic acid & formic acid (CO2-density of 1857 kg m−3 & 1152 kg m−3, compared with condensed liquid CO2 at 993–1096 kg m−3, respectively)." 3/7
Cont'd...
🔸"The relative scalability and compatibility of carbonate salts for stationary storage with #DirectAirCapture, and the potential promise of multiple carriers for CO2 transportation." 4/7
So, results suggested that "solid sorbents do not achieve such ultra-high #storage capacities, but could improve storage over compressed gas tanks on a capacity and energetics basis." 5/7
🚨What if we bet too much on future carbon removal tech and it doesn’t deliver?
New study shows that over-relying on #CDR like DACCS & BECCS could let fossil fuel emissions continue longer, delay action, and raise costs later.
Key findings🧵1/9
2/ Many net-zero plans assume large-scale CDR. But techs like direct air capture (DACCS) & bioenergy with CCS (BECCS) are tiny today and scaling them is risky due to land, energy & cost barriers.
3/ Researchers ran 6 scenarios using GCAM:
-Stage 1: Plan for high or low CDR now
-Stage 2: Learn mid-century whether high CDR is actually feasible or not, and then adjust policy or not
They tracked emissions, energy shifts, costs & who bears the burden.
This episode dives into a radical proposal: using a buried nuclear explosion on the seafloor to break up basalt & speed up carbon removal via Enhanced Rock Weathering. The goal? Sequester 30 years of global CO2.

@InSoilClimate secured its largest funding to date through a €100 million agreement with Key Carbon, accelerating regenerative agriculture and carbon credit generation across Europe.
Canada Nickel partnered with NetCarb to scale mineral carbon sequestration at Crawford. NetCarb's tech could boost CO₂ uptake 10‑fold to 10–15 Mt/year, vs 1.5 Mt via Canada Nickel's proprietary IPT Carbonation.
