“…In the context of this paper, these environmental burdens, resulting from the generation of electricity by each technology and state, are quantified by specific mathematical variables defined in ERCOM-LCIA. The life cycle inventory entries for most power technologies were obtained from the ecoinvent database v3.4 [35], while entries for those technologies missing in LCA repositories, namely coal with CCS [36], solar thermal [37], natural gas with CCS [38] and BECCS [14], were obtained from the literature.…”

“…This insight further underscores the need to incorporate the monetized endpoint indicators in the objective function of ESMs. Natural gas with CCS power plants cause 45% of the damage to ecosystem diversity in solution S3, which is mostly originated in the natural gas production phase [38]. Furthermore, the installation of ground-mounted PV in rural areas affect the species diversity of such lands [48], thereby, contributing to 22% of the damage to ecosystem diversity despite their small share (i.e., 6%)…”

Current energy systems models focus on cost minimization with a bound on some greenhouse gas emissions. This limited environmental scope can lead to mixes that are not consistent with our sustainable development. To circumvent this limitation, we here make use of the concept of monetization and life cycle assessment to quantify the indirect costs of electricity generation in the design of energy systems. Applying our approach to the United States, we found that the indirect costs of electricity generation could be reduced by as much as 63% by meeting the Paris Agreement. Consequently, the total opportunity cost (i.e., direct and indirect costs) of withdrawing from the Paris Agreement and continuing with the current mix would be as high as 1103 ± 206 billion USD2013 in 2030 (i.e., 6% of the United States gross domestic product in 2017). By optimizing the direct and indirect cost of electricity generation concurrently, we found an optimal ecological solution that attains total economic savings compared to the Paris Agreement mix of as much as 373 ± 164 billion USD2013 in 2030. Our work highlights the need to extend the environmental policies that govern energy systems beyond the direct greenhouse emissions to consider other critical environmental criteria.

“…With regards to the CO 2 , two fossil sources, CO 2 captured from coal and natural gas power plants (coal and NG CCU, respectively), were considered, along with direct air capture (DAC CCU). [39][40][41] We assume that the latter is powered by the current mix, which is yet to be decarbonized.…”

“…[28] Similarly, the LCIs for hydrogen production (the electrolytic and SMRÀ CCS H 2 ) and the captured CO 2 are based on literature sources and Ecoinvent.

[47] HH damages, expressed in disability-adjusted life years (DALYs), represent the time that a person is disabled due to disease or accident; EQ damages are specified in local species loss integrated over time (species y); while Res, quantified in USD ($), denotes the extra costs involved in future mineral and fossil resource extraction due to the current exploitation of resources.…”

Hybridization of Fossil‐ and CO₂‐Based Routes for Ethylene Production using Renewable Energy

et al. 2020

Carbon capture and utilization (CCU) has recently gained broad interest in the chemical industry. Direct electro-and thermocatalytic technologies are currently the focus of intense research, where the former employs electricity directly to reduce the CO 2 molecule, while the latter comprises hydrogenation of CO 2 in tandem with electrocatalytic water splitting. So far, it remains unclear which of the two is superior, yet this information is considered critical. Focusing on the platform chemical ethylene, the two CCU routes were compared using state-of-the-art performances with the fossil technology considering different power and CO 2 sources. The thermo-route was found to be, at present, economically and environmentally better, yet under the same electrolyzer efficiencies, the electro-route would become superior. CCU routes could substantially improve the carbon footprint of the fossil ethylene (by 236 %) while decreasing at the same time impacts on human health, ecosystem quality, and resources (64, 140, and 80 %, respectively). However, they are economically unattractive even when considering externalities (indirect cost of environmental impacts), that is, 1.7-to 3.9-fold more expensive compared to the current fossil-based analogue. Acknowledging this limitation, the concept of hybridization was applied as a means to smooth the transition towards more sustainable chemicals. Accordingly, it was found that an optimal hybrid plant could produce carbon-neutral (cradle-to-gate) ethylene with a premium of only 30 % over the current market prices by judiciously combining CCU routes with fossil technologies.

sulfur (LiÀS) batteries hold great promise for powering future electric vehicles, given their high theoretical specific energy of 2600 Wh/kg and low cost. However, the commercialization of LiÀS batteries is being hindered by several serious technical challenges including the corrosion of lithium metal anodes, the formation of lithium dendrites, the shuttle effect of lithium polysulfides, the decomposition of electrolyte, and low conductivity of sulfur and lithium sulfide. In the past decade, atomic layer deposition (ALD) as a new research thrust has been demonstrated to be a very effective technique in dramatically improving the performance of lithium-ion batteries (LIBs), featuring many unique advantages in fabricating sub-nano to nanoscale inorganic films. Stimulated by ALD's benefits, recently more and more research efforts have been reported in ALD for addressing the technical issues of LiÀS batteries and show very promising outcomes. Analogous to ALD, molecular layer deposition (MLD) is a thin-film technique exclusively for polymeric films. Some of the latest studies have uncovered that MLD is an alternative tool for tackling the challenges of LiÀS batteries with exceptional effectiveness. In this review, for the first time, we systematically summarized the progresses of both ALD and MLD in developing superior LiÀS batteries, covering their technical strategies, resulting performance, and the underlying mechanisms. In terms of the functionalities of ALD and MLD in LiÀS batteries, we focus our discussion in two main complementary aspects: (i) surface coatings and (ii) electrode designs.[a] Q. polysulfide, Li 2 S 8 , and the subsequent reductions of Li 2 S 8 to low order polysulfides Li 2 S n (3 n 6), corresponding to the decreasing voltage slope from 2.2 V to~2.1 V. While the lower voltage plateau (1.9-2.1 V) is ascribed to the reductions from the soluble low-order polysulfides (Li 2 S n , 3 n 6) to the insoluble Li 2 S 2 or Li 2 S. During the final stage of a discharge process, the reduction from Li 2 S 2 to Li 2 S is the main reaction step. In a charging process, the discharge product, Li 2 S is oxidized and then finally changed into S 8 .However, LiÀS batteries suffer from a series of major challenges in practice. [20a,f,23] First, the lithium electrode is prone to present heterogeneous deposition and dissolution during charge-discharge processes. In addition, lithium is likely to grow into dendritic structures [24] and the resulting dendrites pose serious risks to the cell safety. The dendritic lithium is possible to penetrate the separator, reach the cathode side, and then short the cell. [24e,25] Second, lithium metal anodes tend to experience corrosion in contact with liquid organic electrolytes such as the widely applied mixture of dioxolane (DOL) and dimethoxyethane (DME), leading to the formation of some gaseous and solid by-products, i. e., solid electrolyte interphase (SEI). [26] The formation of SEI consumes lithium and electrolytes. This may increase cell impedance and lead to the final failu...
