Special Issue Information

Dear Colleagues,

With the great economic development and numerous causes of fossil fuel consumption, the rapid increase in excessive carbon emission has become an urgent issue faced by the world. High CO2 emissions lead to serious environmental and climate problems such as global warming. The Paris Agreement established ambitious climate goals for the world’s countries. To meet the carbon-neutral vision, decarbonation techniques were needed and encouraged. Carbon capture and storage was one of the most effective methods to reduce carbon emissions. It includes the technologies of greenhouse gas capture from fossil-fuel-fired power stations, refineries, chemical plants, etc. Technologies of carbon storage in different media, such as deep saline aquifers, oil and gas reservoirs, coal beds, deep oceans, and so on, also need comprehensively studying.

This Special Issue provides an overview of the latest advances and prospects in the referred topics and contributes to the carbon capture and storage experimental and theoretical investigations. We therefore invite the submission of papers on innovative technical developments, reviews, case studies, analytical studies, and assessment papers from different disciplines, which are relevant to carbon capture methods, CO2 emission distribution, carbon storage mechanisms, underground and in oceans, carbon source and sink matching, CO2-enhanced oil and gas recovery, CO2-assisted natural gas hydrates, and coal bed methane development topics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In biology, respiratory quotient (RQ) is defined as the ratio of CO2 moles produced per mole of oxygen consumed. Recently, Annamalai et al. applied the RQ concept to engineering literature to show that CO2 emission in Giga Tons per Exa J of energy = 0.1 ∗ RQ. Hence, the RQ is a measure of CO2 released per unit of energy released during combustion. Power plants on earth use a mix of fossil fuels (FF), and the RQ of the mix is estimated as 0.75. Keeling’s data on CO2 and O2 concentrations in the atmosphere (abbreviated as atm., 1991–2018) are used to determine the average RQGlob of earth as 0.47, indicating that 0.47 “net” moles of CO2 are added to which means that there is a net loss of 5.6 kg C(s) from earth per mole of O2 depleted in the absence of sequestration, or the mass loss rate of earth is estimated at 4.3 GT per year. Based on recent literature on the earth’s tilt and the amount of water pumped, it is speculated that there could be an additional tilt of 2.7 cm over the next 17 years. While RQ of FF, or biomass, is a property, RQGlob is not. It is shown that the lower the RQGlob, the higher the acidity of oceans, the lesser the CO2 addition to atm, and the lower the earth’s mass loss. Keeling’s saw-tooth pattern of O2 is predicted from known CO2 data and RQGlob. In Part II, the RQ concept is expanded to define energy-based RQGlob,En, and adopt the CO2 and O2 balance equations, which are then used in developing the explicit relations for CO2 distribution amongst atm., land, and ocean, and the RQ-based results are validated with results from more detailed literature models for the period 1991–2018.
