To address the intermittency problems of variable renewable energy (VRE) in low-carbon energy systems, flexibility has become increasingly important. Electrified transportation exhibits great potentialto provide essential flexibility. In this work, we analyzed and compared the flexibility values of battery electric vehicles (BEVs) and fuel cell electric vehicles (FCEVs) for planning and operating interdependent electricity and hydrogen supply infrastructures while considering battery degradation impacts and costs. A cross-scale framework involving both macro-level and micro-level models was proposed to compute the values of flexible EV charging. At the macro level, a sector-coupling planning model was adopted to estimate the system cost reduction from flexible EV charging incorporating battery degradation costs. Battery degradation cost computation for BEVs was based on micro-level simulations of battery degradation via a porous electrode theory-based model under various charging-time constraints and temperatures. The results show that the flexibility values of BEVs are significantly reduced by considering the battery degradation cost and becomes comparable to those of FCEVs. Fast charging and a low-temperature environment could reduce the flexibility values of BEVs due to increased degradation. Under theelectrolytic-hydrogen only pathway, with more stronglycoupled power and hydrogen supply chains, the flexibility values of BEVs are significantly reduced because of the substitution effect of the less expensive flexibility from hydrogen storage. Our findings imply that policies (e.g., the hydrogen pathway) and relevant management technologies (e.g., battery fast charging and thermal management) for BEV battery degradation mitigation are crucial to shaping the comparative flexibility advantage of the two transportation electrification pathways.

“…The Intergovernmental Panel on Climate Change (IPCC) has issued a warning that if global warming is to be limited, fossil fuel emissions must be reduced to half by 2030 and to zero by 2050. , Even though steps are being taken to minimize the emissions and it has slowed over the past few years, it is still far from the target . To minimize the dependence on oil products due to depletion of fossil fuels, extreme global warming, and a continuous increase in the global energy demand, the world is transiting toward renewable energy sources and appropriate energy storage systems. − Moreover, the energy crisis has encouraged researchers to work on clean energy sources such as the biomass, hydropower, solar, wind, and biodiesel for the generation of electricity. , Electrical energy storage systems with high power density and high energy density are the focus of researchers at this point, and considerable developments are realized that might generate some headway. − …”

As the fossil fuels are running out, the world is advancing toward renewable energy sources and related energy storage technologies. Metal−air batteries have received significant prominence due to their high energy density compared to conventional batteries and fuel cells. Particularly, lithium−air battery has garnered tremendous attention owing to its highest theoretical energy density alongside a large cell capacity. However, technical challenges pertaining to the cathode such as cell voltage drop, carbon electrode corrosion, detrimental side reactions, electrode pore clogging, etc., still persist and hinder their commercial success. So, to improve their overall performance and make them a practical success, various cathode materials are being investigated by researchers around the globe. Nanoengineering of two-dimensional materials is one such subject under extensive investigation, where MXenes have recently emerged as strong candidates with their unique properties such as high hydrophilicity, large interlayer spacing, and high mechanical stability. MXenes with high electrical conductivity and catalytic activity possess a huge potential for applications in energy storage. Over the past few years, more than 30 MXenes with different chemistries have been synthesized for various applications. Yet, titanium carbide MXene (Ti 3 C 2 T x ) remains as the most studied MXene, mainly, but not exclusively, for its high electrical conductivity, which makes it a suitable choice for electrode material. This review presents an overview of MXene, its syntheses, and an up-to-date summary from the literature focused on the potential use of TiC MXenes as cathodes in Li−air batteries.

“…Several renewable energies, like wind and solar power, are characterized by high fluctuations, as a result of the prevailing conditions, and therefore demand storage solutions (Jafari et al, 2022;Polleux et al, 2022). As such, technologies like the power-to-gas concept have been developed, contributing to a flexible energy storage system (Mehrjerdi et al, 2022).…”

Trickle-Bed Bioreactors for Acetogenic H2/CO2 Conversion

et al. 2022

Acetic acid is an essential industrial building block and can be produced by acetogenic bacteria from molecular hydrogen (H2) and carbon dioxide (CO2). When gasses are supplied as substrates, bioreactor design plays an important role for their availability. Trickle-bed bioreactors (TBs) have an enhanced gas-to-liquid mass transfer and cells remain in the system by forming a biofilm on the carriers. So far, TBs have been investigated extensively for bio-methanation processes, whereas studies for their use in acetic acid production are rare. In this study, we evaluated the reproducibility of two parallel TBs for acetic acid production from H2:CO2 (= 70:30) by a mixed culture with a gas flow rate of 3.8 mL min−1 and a medium flow rate of 10 mL min−1. Additionally, the effect of glucose addition during the starting phase on the resulting products and microbial composition was investigated by setting up a third TB2. Partial medium exchanges to decrease the internal acetic acid concentration (AAC) combined with recycling of withdrawn cells had a positive impact on acetic acid production rates with maxima of around 1 g L−1 d−1 even at high AACs of 19–25 g L−1. Initial glucose addition resulted in the accumulation of unwanted butyric acid up to concentrations of 2.60 ± 0.64 g L−1. The maximum AAC of 40.84 g L−1 was obtained without initial glucose addition. The main families identified in the acetogenic TBs were Peptococcaceae, Ruminococcaceae, Planococcaceae, Enterobacteriaceae, Clostridiaceae, Lachnospiraceae, Dysgonomonadaceae and Tannerellaceae. We conclude that a TB is a viable solution for conversion of H2/CO2 to acetate using an anaerobic enrichment culture.
