Recent research submitted in the @researchsquare โ€œpresents first-of-its-kind process concepts for co-removal of #methane and #CO2ย that combine the catalytic conversion of methane step (thermal/photo-catalytic) with #CO2Capture (#DirectAirCapture).โ€
1/17 Image
โ€œThe 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.โ€

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:

"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 โ€” or $6 million per year โ€” under the 45Q tax credit."

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

continuous operation of a designed #DAC system comprised of two
parallel units with a regeneration temperature of 100ยฐC," research finds.

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

(1/9) Iโ€™ve seen a lot of op-eds about how awful it is that #CCS was included in the #IRA. Most lack nuance, because they havenโ€™t clocked that the #energytransition isnโ€™t just about the power sector anymore. Sorry #energytwitter. So, a ๐Ÿงต on why carbon capture still has a place.
(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 canโ€™t do without CCS. Process emissions are just as harmful as combustion. And weโ€™re past the point where abatement of emissions is enough. That means removals, which means #DirectAirCapture.

If you ever wanted to acquire #carbonoffsets, you've surely faced the question of categorization. Here is an easy taxonomy ๐Ÿ‘‡ ๐Ÿงต
1/ Two weeks ago I highlighted the difference between carbon emission reduction and removal projects.

The idea of #CarbonReduction is to pay others to reduce emissions in your place. But your output remains in the system. One plus zero.
2/ #CarbonRemoval on the other hand scrubs carbon directly from the atmosphere. Plus one, minus one.

But technically, the #carbonmarket makes no difference. A ton is a ton.

@CatalystPod with @shaylekann gets into the weeds with @rutherdan on the complexities and options for decarbonizing aviation. From SAFs to electric propulsion, this one is a must listen!

Today @POTUS unveiled the #AmericanJobsPlan that includes transformative investments in clean energy that could kickstart the economy, create millions of good jobs and tackle the #climatecrisis head on. Here are a few key measures in the proposal [THREAD]
Electric Vehicles: $174 billion to compete in the global #EV market and support American workers to make batteries and EVs, electrify federal fleet, replace 50,000 diesel transit vehicles & work w/ state/local governments to build national network of 500,000 EV chargers by 2030.
Electric School Buses: Electrify at least 20% of US school bus fleet through new Clean Buses for Kids Program at @EPA and set the country on a path to 100% clean buses. Our analysis shows electric buses can have major health, cost-savings & jobs benefits. wri.org/publication/maโ€ฆ
