ExxonMobil expands agreement with Global Thermostat; sees promise in CO2 direct air capture technology

ExxonMobil and Global Thermostat (GT) have expanded their joint development agreement following 12 months of technical evaluation to determine the feasibility and potential scalability of Global Thermostat’s technology that captures carbon dioxide directly from the air.

GT believes ExxonMobil’s financial and technological strength will enable it to scale up its carbon removal technology to pull a gigaton of carbon out of the atmosphere and to continue to grow to remove the 40 gigatons of CO2 per year that the UN’s Intergovernmental Panel on Climate Change (IPCC) says is required to avoid irreversible and catastrophic damage to the planet.

The United Nations Framework Convention on Climate Change has said that CO2 capture, use and storage “is a key technology for the decarbonization of the energy sector in the long term. ” In addition, the International Energy Agency recognizes that CO2 removal is expected to play a “key role” in the energy transition.

Global Thermostat’s CO2 capture uses proprietary amine-based adsorbents to remove CO2 from the air. These compounds act together like a filter to efficiently capture CO2, which can then be stored safely underground, used to make chemicals, consumer products or construction materials.

ExxonMobil has a strong network of research partnerships across universities and national labs. As a part of the joint development agreement with Global Thermostat, ExxonMobil will leverage this network and engage the expertise of university partners that have strong expertise in material science and the US Department of Energy’s National Labs that offer expertise in CO2 capture and utilization. Global Thermostat will also engage its network of universities and industrial partners to help scale its technology.



" the International Energy Agency recognizes that CO2 removal is expected to play a “key role” in the energy transition"
I don't see that. IMO, the energy transition is about generating energy without CO2, not about taking CO2 out of the air. This is a different thing - both are good and useful, but they are different and independent (IMO).

It always strikes me as easier to not put the CO2 into the atmosphere in the first place, rather than taking it out afterwards. (The only exception I can think of is aviation).
If you put the same amount of effort into closing and substituting Coal plants and burning forests, you would get much more bang for your buck.

Surface transport can be electrified, as can most sea transport (eventually).
Air transport is much harder as batteries and hydrogen tanks are bulky and heavy for long / medium range.
