We present the first-of-its-kind process concepts for co-removal of methane and CO2 and calculate the total energy demand per ton of CO2-equivalent (referred to as CO2eq in the remaining text) removed. Much of the emphasis in this work has been on presenting the process concepts for CH4...
which was triggered when methane production rates were low. Since methylotrophic methanogenesis rates are much lower in marine sediments than under optimal conditions in pure culture, CO2conversion to methane is an important but previously overlooked methanogenic process in sediments...

Thus, the ratio of the feed can be used to control conversion; an equivalent conversion of CO2 and CH4 would be approached by having a CO2/CH4 ratio of 1.2. However, an increase in CO2 content favors the RWGS reaction and therefore causes a decline in the H2/CO production ratio. ...
The new catalyst costs 18,000 yuan (about 2,650 U.S. dollars) per tonne, equivalent to one-10,000th of the price of traditional metal catalysts, said lead researcher Zuo Zhiwei. It also has great potential application in the pharmaceutical and agricultural chemistry industries. Some Chinese ...
CO2 and CH4 emissions are presented in units of CO2 equivalent (CO2-eq). CO2-eq emissions are calculated by multiplying CH4 emissions by the GWP of CH4, and adding this value to the CO2 emissions. The GWP measures the relative heat-trapping ability of CH4 compared to CO2, and is a funct...
"We found that bio-methane produced through anaerobic digestion emits far less than its fossil natural gas equivalent," says Sharath Ankathi, the paper's lead author and a PhD student at Michigan Tech. Studying each product's carbon footprint is a way to assess its social, environmental and...
In 2019, heating in the built environment emitted 23Mt of [Math Processing Error]CO2 equivalent. This value represents [Math Processing Error]12.5% of the total emissions in the Netherlands [89]. The Dutch government has the goal of reducing emissions by [Math Processing Error]49% by 2030 an...

an annual cycle, CO2-equivalent CH4emissions offset 28 and 35% of the carbon sink capacity attributed to atmospheric CO2uptake in the macroalgae and mixed vegetation habitats, respectively, and augment net CO2release of unvegetated sediments by 57%. Accounting for CH4alongside CO2sea-air fluxes ...
