Frontiers | Economics of CO2 Utilization: A Critical Analysis | …

The economics of CO2 utilization are discussed from a critical perspective, with a concise analysis of the state-of-the-art of economics in power-to-X (methanol, methane). The main elements of the analysis of the economics are commented to provide guidelines on how to interpret the techno-economic results in the area of CO2 utilization. It remarks the need of a careful analysis of the specific ...

Coal gasification in CO2 atmosphere and its kinetics since …

 · Fig. 2 shows the variation of the gasification rate with the carbon content present in the coal in the CO 2 atmosphere at atmospheric pressure and 900 C. In the figure, Miura et al. found that the gasification reactivity data of chars, prepared from 68 different coals by different authors , , , , were very scattered for low-rank coals (%C < 80), but the reactivity was higher than that obtained ...

Inerting system

An inerting system decreases the probability of combustion of flammable materials stored in a confined space, especially a fuel tank, by maintaining a chemically non-reactive or "inert" gas, such as nitrogen,[1] in such a space. "Inerted" fuel tanks may be used on land, or aboard ships[2] or aircraft.

Negative emissions—Part 2: Costs, potentials and side …

 · Side effects. A wide variety of biophysical, social and economic side-effects are considered in the AR literature. One of the most prominent issues from a climate perspective is albedo change, which finds significant attention particularly in global studies (Anderson et al 2011 , Arora and Montenegro 2011 , Betts et al 2007 , Jackson et al 2008 , Wang et al 2014 ).

Recognizing the Value of Collaboration in Delivering …

Removing CO2 from the atmosphere is needed in addition to deep mitigation of CO2 emissions. As not all countries possess the geo-biophysical assets to provide sustainable, permanent, and affordable CO2 removal, a cooperative and collaborative approach to CO2 removal, based on equitable burden sharing and CO2 sink trading, is needed to meet global CO2 removal goals at least cost.

The Covid Lockdown and CO2 | Watts Up With That?

 · On the “natural” side he counts emissions of CO2, and ignores removals of CO2. On the “human” side he counts net emissions of CO2. If you compare apples-to-apples (i.e., net CO2 flux, from both sources), it is obvious that mankind is responsible for the increase in CO2 level.
