Science Daily December 29, 2021 From the gene-sequencing analyses of the behaviour of CO2 within a CO2-Eenhanced Oil Recovery (EOR) flooded oil field an international team of researchers (UK, USA – Woods hole Oceanographic Institution, industry, France, Canada) has shown that up to 74% of CO2 left behind by CO2-EOR was dissolved in the groundwater. It also revealed, that microbial methanogenesis converted as much as 13-19% of the injected CO2 to methane, which is a stronger greenhouse gas than CO2. The authors suggest that this process is occurring at other CO2-rich natural gas fields and CO2-EOR oil fields. Temperature is […]

Liquid marbles: how this tiny, emerging technology could solve carbon capture and storage problems
Phys.org December 8, 2021 Research shows “liquid marbles”—tiny droplets coated with nanoparticles—could possibly address current challenges in materials used to capture carbon. Gas from the reactor hits the marbles, where it clings to the nanoparticle outer shell, the gas then reacts with the liquid within, separating the CO₂ and capturing it inside the marble. CO₂ can be taken out and stored underground, and then recycle the liquid for future processing. This process can be a more time and cost-efficient way of capturing CO₂. However, many properties of liquid marbles remain elusive as physical experiments have their limitations. An international team […]
