“…Compared to MEA, this process shows a reduction of emissions and energy cost savings. In [4], Manuilova compared power units with MEA sorbents and without CO 2 capture and corroborated the general conclusions of other research works which reported a decrease in SO 2 and particulate matter and an increase in NOx emissions due to MEA emissions. Additionally, increased levels of smog, water consumption, and water toxicity were also calculated.…”

Environmental Assessment of a Coal Power Plant with Carbon Dioxide Capture System Based on the Activated Carbon Adsorption Process: A Case Study of the Czech Republic

et al. 2020

The Czech Republic is introducing new technological concepts for mitigation of greenhouse gases (GHG) in coal-based energy industries. One such technology, in power plants, is post combustion CO2 capture from flue gases by activated carbon adsorption. A life cycle assessment (LCA) was used as the assessment tool to determine the environmental impacts of the chosen technology. This article focuses on a comparative LCA case study on the technology of temperature-swing adsorption of CO2 from power plant flue gases, designed for the conditions of the Czech Republic. The LCA study compares the following two alternatives: (1) a reference power unit and (2) a reference power unit with CO2 adsorption. The most significant changes are observed in the categories of climate change potential, terrestrial acidification, and particulate matter formation. The adsorption process shows rather low environmental impacts, however, the extended LCA approach shows an increase in energy demands for the process and fossil depletion as a result of coal-based national energy mix. The feasibility of the study is completed by the preliminary economical calculation of the payback period for a commercial carbon capture unit.

“…Several researchers have examined greenhouse gas emission related to CO 2 -EOR life cycle operations, including a scenario for the Permian Basin of West Texas CO 2 -EOR, EOR in the Williston Basin Weyburn field based on economic optimization, environmental effects of CO 2 -EOR, emission factors for CO 2 -EOR versus other conventional oil production and electricity generation, and postcombustion capture and CO 2 -EOR for the Boundary Dam Project . The International Energy Agency examined the potential for EOR to reduce net CO 2 emissions on large scales .…”

Large CO₂ Storage Volumes Result in Net Negative Emissions for Greenhouse Gas Life Cycle Analysis Based on Records from 22 Years of CO₂-Enhanced Oil Recovery Operations

2020

Emissions were documented in a greenhouse gas emission life cycle analysis of 22 years of CO2-enhanced oil recovery (CO2-EOR) operations for a site in the Northern Michigan Basin, U.S. At the site, CO2 was cycled through a series of 10 carbonate reef structures 1500–2000 m deep in the subsurface. The CO2 mobilized oil in the reefs, and the operator produced 294 321 metric tons (2 290 000 barrels) of oil with CO2-EOR at the site from 1996 to 2017. In the process, a total of 2 089 000 metric tons of CO2 were stored in the deep rock formations, which is a very large volume for CO2-EOR applications of this scale. The life cycle analysis accounted for greenhouse gas emissions related to CO2 capture, compression, pipeline transport, CO2 injection, oil processing, CO2 recycle, dehydration, fugitive emissions, construction, land use, well drilling, oil transport, oil refining, hydrocarbon product combustion, and other processes. The analysis was based on site-specific operational records such as natural gas usage, drilling records, and system flow metering. Altogether, the upstream CO2 capture, “gate-to-gate” CO2-EOR operations, and downstream fuel product refining/combustion had total emissions of 1 929 443 metric tons of CO2 equivalent. Thus, the life cycle analysis showed −159 907 metric tons of CO2 equivalent net balance for the CO2-EOR system for 1996–2017. The CO2-EOR system obtains CO2 from a gas processing facility that separates CO2 from natural gas produced in the area, and the CO2 would be otherwise vented to the atmosphere. A ready source of CO2 that allowed a large volume of associated CO2 storage, compressors that run on natural gas, a small pipeline distribution network, highly contained reservoirs, and government incentives to encourage CO2 storage also contributed to the lower CO2 emission balance when compared to other CO2-EOR life cycle studies. While this site had many favorable factors to result in net negative emissions, it provides an example of managing CO2-EOR operations and optimizing associated CO2 storage to reduce net greenhouse gas emissions.

“…351 The capture capacity has tripled since 2010, but is far from the 2050 net zero scenario level of 1150 Mt CO 2 captured per year. This includes the Boundary Dam Carbon Capture Project from SaskPower in Saskatchewan (Canada) 352 and the Sleipner offshore gas facility in Norway. 353 This latter project, with its capture capacity of 0.9 Mt/year, is the first large-scale CCS project which has now stored more than 20 Mt of CO 2 in a deep saline formation since 1996.…”

Metals and alloys are among the most technologically important materials for our industrialized societies. They are the most common structural materials used in cars, airplanes and buildings, and constitute the technological core of most electronic devices. They allow the transportation of energy over great distances and are exploited in critical parts of renewable energy technologies. Even though primary metal production industries are mature and operate optimized pyrometallurgical processes, they extensively rely on cheap and abundant carbonaceous reactants (fossil fuels, coke), require high power heating units (which are also typically powered by fossil fuels) to calcine, roast, smelt and refine, and they generate many output streams with high residual energy content. Many unit operations also generate hazardous gaseous species on top of large CO2 emissions which require gas-scrubbing and capture strategies for the future. Therefore, there are still many opportunities to lower the environmental footprint of key pyrometallurgical operations. This paper explores the possibility to use greener reactants such as bio-fuels, bio-char, hydrogen and ammonia in different pyrometallurgical units. It also identifies all recycled streams that are available (such as steel and aluminum scraps, electronic waste and Li-ion batteries) as well as the technological challenges associated with their integration in primary metal processes. A complete discussion about the alternatives to carbon-based reduction is constructed around the use of hydrogen, metallo-reduction as well as inert anode electrometallurgy. The review work is completed with an overview of the different approaches to use renewable energies and valorize residual heat in pyrometallurgical units. Finally, strategies to mitigate environmental impacts of pyrometallurgical operations such as CO2 capture utilization and storage as well as gas scrubbing technologies are detailed. This original review paper brings together for the first time all potential strategies and efforts that could be deployed in the future to decrease the environmental footprint of the pyrometallurgical industry. It is primarily intended to favour collaborative work and establish synergies between academia, the pyrometallurgical industry, decision-makers and equipment providers. Graphical abstract Highlights A more sustainable production of metals using greener reactants, green electricity or carbon capture is possible and sometimes already underway. More investments and pressure are required to hasten change. Discussion Is there enough pressure on the aluminum and steel industries to meet the set climate targets? The greenhouse gas emissions of existing facilities can often be partly mitigated by retrofitting them with green technologies, should we close plants prematurely to build new plants using greener technologies? Since green or renewable resources presently have limited availability, in which sector should we use them to maximize their benefits?
