“…The limiting current is defined as the current when steady-state CO 2 concentration reaches zero at the depth of the PAQ electrode. CO 2 (15%) was used in the calculation, which is the approximate concentration expected in many carbon capture applications ( 41 ). The limiting current decreases with decreasing gas pressure and/or increasing electrode thickness, with the value being ~2 mA cm −2 for a 50-μm electrode under 1 atm pressure ( Fig.…”

Electrochemically mediated gating membrane with dynamically controllable gas transport

et al. 2020

The regulation of mass transfer across membranes is central to a wide spectrum of applications. Despite numerous examples of stimuli-responsive membranes for liquid-phase species, this goal remains elusive for gaseous molecules. We describe a previously unexplored gas gating mechanism driven by reversible electrochemical metal deposition/dissolution on a conductive membrane, which can continuously modulate the interfacial gas permeability over two orders of magnitude with high efficiency and short response time. The gating mechanism involves neither moving parts nor dead volume and can therefore enable various engineering processes. An electrochemically mediated carbon dioxide concentrator demonstrates proof of concept by integrating the gating membranes with redox-active sorbents, where gating effectively prevented the cross-talk between feed and product gas streams for high-efficiency, directional carbon dioxide pumping. We anticipate our concept of dynamically regulating transport at gas-liquid interfaces to broadly inspire systems in fields of gas separation, miniaturized devices, multiphase reactors, and beyond.

In this study different possibilities and the feasibility of applying carbon capture at an integrated steel mill based on blast furnace process, in order to reduce carbon dioxide emissions were studied. Technologies considered for capturing of CO2 are post-combustion carbon capture (PCC) and oxygen blast furnace route (OBF). Post-combustion capture for the integrated steel mill was evaluated in an earlier study by Arasto et Al. and Tsupari et Al. [1,2]. Implications of different capture amounts, different solvents for post-combustion capture and process integration levels to the greenhouse gas balance and operation economics are compared to the steel production base case with varying costs of CO2 emission allowances. Furthermore the effect of reducing the carbon intensity of steel production on the final steel production cost is evaluated. Iron and steel industry is responsible of around 5% of the overall global CO2 emissions [3]. Steel production based on the blast furnace and basic oxygen furnace-based route is the main technology corresponding to the growth in global steel production [4] and this technology route is also the main source of CO2 emissions in the iron and steel industry. The assessment of potential and cost for carbon capture and storage in the iron and steel industry is based on a case study on Ruukki Metals Oy's steel mill in Raahe. The mill is situated on the northeastern coast of the Gulf of Bothnia. It is the largest integrated steel mill in the Nordic countries producing hot rolled steel plates and coils. It is also the largest CO 2 point source in Finland emitting approximately 4 Mton of CO 2 / year. Raahe steel mill produces district heat for use in the town nearby as well as for use onsite for heating of the premises. The power plant is connected to the national electricity grid, and thus it is possible to buy and sell electricity across system boundary. In contrast to power plant applications of CCS, CO 2 emission sources at an integrated steel mill are scattered around the industrial site and the flue gases are led to several stacks. Due to this, the capture process evaluation is much more complex and requires system level optimization. Carbon capture processes and process integration options were modeled using Aspen Plus process modeling software and the results were used to estimate CO 2 emission reduction possibilities and carbon abatement costs at the integrated steel mill from an investor's point of view. Different heat integration options and heat utilization scenarios were investigated and optimized with a custom-built CC-Skynet™ economics toolkit. Heat available for solvent regeneration varies between these heat utilization scenarios and thus different capture amount are investigated depending on the heat available for solvent regeneration in different case 7118Antti Arasto et al. / Energy Procedia 37 ( 2013 ) 7117 -7124 studies. Also different technologies related to oxygen blast furnace were considered, both for oxygen production and for top gas treatment. The application ...

“…However, Boysen et al (2017) note that using biomass plantations to sequester carbon would reduce biodiversity, because they are likely to be monocultures, and occupy land that might otherwise be used for food production. These authors conclude: '…that this strategy of sequestering carbon is not a viable alternative to aggressive emission reductions…' Most current research on 'aggressive emission reductions' is focussed on the integration of new technologies to capture CO2 from flue gasses in power plants, which are responsible for about 80% of the worldwide CO2 emissions (Romano et al, 2013). Methods based on exposing flue gas to water under suitable conditions ('hydrate-based processing') is a promising and high efficiency technology for CO2 capture, but the high cost of maintaining suitable conditions for hydrate formation is preventing wide industrial application of this technology (Li et al, 2019).…”

To combat climate change, proposals have been made to develop methods that would pull carbon dioxide out of Earth's atmosphere. One recommended approach is to remove CO2 from the atmosphere with activities such as reforestation and changing forest management and agricultural practices to enhance soil carbon storage. However, it is also noted that such activities would limit land for food production and negatively affect biodiversity. Furthermore, decay of dead wood and fallen leaves in natural forests releases huge quantities of CO2 and other greenhouse gases back into the atmosphere. The only other carbon-sequestration technique that is widely considered is the application of CO2 capture processes to flue gases of power plants, which are responsible for about 80% of the worldwide CO2 emission from large stationary sources. Hydrate-based processing is a promising technology for CO2 capture as it results in high CO2 recovery, but its high cost prevents this technology having much impact. In this note I suggest that the ability of marine organisms (shellfish and coccolithophore algae) to remove permanently CO2 from the atmosphere into solid (crystalline) CaCO3 should be harnessed. I suggest that if the level of finance and effort that are readily
