🚨NEW STUDY🚨

Recent research submitted in the @researchsquare “presents first-of-its-kind process concepts for co-removal of #methane and #CO2 that combine the catalytic conversion of methane step (thermal/photo-catalytic) with #CO2Capture (#DirectAirCapture).”
1/17

“The proposed solution to co-remove methane and CO2 from low concentration sources has the potential of #removing more CO2-equivalents from the atmosphere at lower energy penalty when compared to technologies that focus on removing only CO2 from the air, the study affirmed.”

Based on the analysis of this study, researchers summarize the following challenges and opportunities with the proposed solution for co-removing methane and CO2 from the atmosphere:

🚨𝐍𝐄𝐖 𝐏𝐀𝐏𝐄𝐑🚨

A lately published paper by @rosner_fabian, Schamberger & @hanna_breunig present "a novel #DirectAirCapture concept whereby cooling towers at #geothermal power plants are hybridized to capture CO2 at very #lowcost."

Details in a 🧵below⬇️
[1/6]

"The system design is elegant in its ability to overcome key technical challenges and highlights the potential for using existing infrastructure to lower #DirectAirCapture cost and land footprint, and secure utilities and public confidence."
2/6

"The techno-economic analysis suggests a cost-of-capture of $100 per metric tonne of CO2 is feasible, allowing #geothermal facilities to increase their net profit by $29 per metric tonne of CO2 captured — or $6 million per year — under the 45Q tax credit."

🚨PAPER🚨

#DAC of CO2 from the atm. is being explored as a tech. that can contribute to the goal of reaching #NetZero CO2 emissions.

A new study led by @DonglongFu1 showed that the use of zeolitic materials are feasible for DAC when it is integrated with H2O harvesting.
🧵
1/7

"A combination of a commercially available desiccant, AQSOA-Z02A, and a mordenite-type zeolite (MOR) enables
continuous operation of a designed #DAC system comprised of two
parallel units with a regeneration temperature of 100°C," research finds.
2/7

Furthermore, "the system
using pure #zeolite alone requires regeneration at temperatures between 200°C and 300°C."

🚨NEW PAPER 🚨

"The energy-intensive nature of CO2 absorption-desorption processes has restricted deployment of #DAC operations. So, catalytic solvent regeneration is a valid solution to tackle this case by accelerating CO2 desorption at lower regeneration temperatures."

(1/9) I’ve seen a lot of op-eds about how awful it is that #CCS was included in the #IRA. Most lack nuance, because they haven’t clocked that the #energytransition isn’t just about the power sector anymore. Sorry #energytwitter. So, a 🧵 on why carbon capture still has a place.

@BloombergNEF

(2/9) First, I get this. I was a huge #CCS skeptic. Two things changed my mind: modelling pathways to #netzero for materials with my @BloombergNEF team, and the #BNEFNEO team's carbon budgets for industry. Sobering work that taught me a lot.

(3/9) Some industries just can’t do without CCS. Process emissions are just as harmful as combustion. And we’re past the point where abatement of emissions is enough. That means removals, which means #DirectAirCapture.
