ExxonMobil and Global Thermostat signed an agreement to advance technology that they said can capture and concentrate carbon dioxide emissions from industrial sources, including power plants, and the atmosphere.

The companies will evaluate the potential scalability of Global Thermostat’s carbon capture technology for large industrial use. If technical readiness and scalability is established, pilot projects at ExxonMobil facilities could follow.

Global Thermostat uses amine-based chemical sorbents that are bonded to porous, honeycomb ceramic monoliths that act together as carbon sponges. These carbon sponges adsorb CO2 directly from the atmosphere, smokestacks or a combination of both. The captured CO2 is then stripped off and collected using low-temperature steam (85° C to 100° C). The company said that its process results in 98% pure CO2 at standard temperature and pressure.

ExxonMobil earlier in 2019 committed to spend up to $100 million over 10 years on research with the U.S. Department of Energy’s National Renewable Energy Laboratory and National Energy Technology Laboratory to bring lower-emissions technologies to commercial scale.
