Challenges and opportunities for battery health estimation:Bridging laboratory research and real-world applications

Addressing climate change demands a significant shift away from fossil fuels,with sectors like electricity and transportation relying heavily on renewable energy.Integral to this transition are energy storage systems,notably lithium-ion batteries.Over time,these batteries degrade,affecting their efficiency and posing safety risks.Monitoring and predicting battery aging is essential,especially estimating its state of health(SOH).Various SOH estimation methods exist,from traditional model-based approaches to machine learning approaches.

Policy and Management of Carbon Peaking and Carbon Neutrality:A Literature Review

The vision of reaching a carbon peak and achieving carbon neutrality is guiding the low-carbon transition of China’s socioeconomic system.Currently,a research gap remains in the existing literature in terms of studies that systematically identify opportunities to achieve carbon neutrality.To address this gap,this study comprehensively collates and investigates 1105 published research studies regarding carbon peaking and carbon neutrality.In doing so,the principles of development in this area are quantitively analyzed from a space–time perspective.At the same time,this study traces shifts and alterations in research hotspots.This systematic review summarizes the priorities and standpoints of key industries on carbon peaking and carbon neutrality.Furthermore,with an emphasis on five key management science topics,the scientific concerns and strategic demands for these two carbon emission-reduction goals are clarified.The paper ends with theoretical insights on and practical countermeasures for actions,priority tasks,and policy measures that will enable China to achieve a carbon-neutral future.This study provides a complete picture of the research status on carbon peaking and carbon neutrality,as well as the research directions worth investigating in this field,which are crucial to the formulation of carbon peak and carbon neutrality policies.

Five tips for China to realize its co-targets of climate mitigation and Sustainable Development Goals(SDGs)

In 2018,a total of US$166 billion global economic losses and a new high of 55.3 Gt of CO_(2)equivalent emission were generated by 831 climate-related extreme events.As the world’s largest CO_(2)emitter,we reported China’s recent progresses and pitfalls in climate actions to achieve climate mitigation targets(i.e.,limit warming to 1.5-2°C above the pre-industrial level).We first summarized China’s integrated actions(2015 onwards)that benefit both climate change mitigation and Sustainable Development Goals(SDGs).These projects include re-structuring organizations,establishing working goals and actions,amending laws and regulations at national level,as well as increasing social awareness at community level.We then pointed out the shortcomings in different regions and sectors.Based on these analyses,we proposed five recommendations to help China improving its climate policy strategies,which include:1)restructuring the economy to balance short-term and long-term conflicts;2)developing circular economy with recycling mechanism and infrastructure;3)building up unified national standards and more accurate indicators;4)completing market mechanism for green economy and encouraging green consumption;and 5)enhancing technology innovations and local incentives via bottom-up actions.

Climate or Carbon Mitigation Engineering Management

1.Introduction Carbon mitigation engineering,also known as climate engineering internationally,is an umbrella term of engineering measures targeted at combating climate change and achieving carbon neutrality.Climate or mitigation engineering can be commonly divided into three categories based on technological principles[1]:(1)carbon dioxide removal(CDR),which has the potential to achieve negative emissions by removing atmospheric carbon dioxide[2].

Could the EU carbon border adjustment mechanism promote climate mitigation?An economy-wide analysis

Due to concerns about carbon leakage and sectoral competitiveness,the European Union(EU)proposed implementing the carbon border adjustment mechanism(CBAM).The effectiveness and potential negative consequences of CBAM have aroused extensive discussion.From the perspective of the economy-wide analysis,this study uses a global computable general equilibrium model to explore the rationality of CBAM from the aspects of socioeconomic impact and the effects of promoting climate mitigation.Furthermore,the potential alternative mechanism of CBAM is proposed.The results show that CBAM can reduce the EU's gross domestic product(GDP)loss;however,the GDP loss in all other regions increases.Moreover,CBAM raises household welfare losses in most regions,including the EU.Second,although CBAM can reduce the marginal abatement cost in eight regions,it comes at the cost of greater economic losses.Furthermore,the economic and household welfare cost of raising emissions reduction targets in regions like the USA and Japan is substantially higher than the impact of passively accepting the CBAM;therefore,CBAM's ability to drive ambitious emission reduction initiatives may be limited.Finally,for the potential alternative mechanism,from the perspective of reducing economic cost and household welfare losses,the EU could implement domestic tax cuts in the short-term and promote global unified carbon pricing in the long-term.

Modeling the dynamic impacts of maritime network blockage on global supply chains

Recent phenomena such as pandemics,geopolitical tensions,and climate change-induced extreme weather events have caused transportation network interruptions,revealing vulnerabilities in the global supply chain.A salient example is the March 2021 Suez Canal blockage,which delayed 432 vessels carrying cargo valued at$92.7 billion,triggering widespread supply chain disruptions.Our ability to model the spatiotemporal ramifications of such incidents remains limited.To fill this gap,we develop an agent-based complex network model integrated with frequently updated maritime data.The Suez Canal blockage is taken as a case study.The results indicate that the effects of such blockages go beyond the directly affected countries and sectors.The Suez Canal blockage led to global losses of about$136.9($127.5–$147.3)billion,with India suffering 75%of these losses.Global losses show a nonlinear relationship with the duration of blockage and exhibit intricate trends post blockage.Our proposed model can be applied to diverse blockage scenarios,potentially acting as an earlyalert system for the ensuing supply chain impacts.Furthermore,high-resolution daily data post blockage offer valuable insights that can help nations and industries enhance their resilience against similar future events.

中国碳中和技术发展路径

Carbon neutrality has been considered a new focus of countries for achieving the goal of the Paris Agreement.China has pledged to peak CO_(2) emissions before 2030 and achieve carbon neutrality before 2060,and a"1+N"policy framework has been built to guide the implementations.Scientific and technological innovation has been emphasized as one of the key strategies to establish an innovation system,strengthen research,and promote applications of green and low-carbon technologies[1].Despite numerous studies and policies on decarbonization technologies,studies focusing on technological development pathways for China’s carbon neutrality are needed[2].

Special issue:Transition management of energy systems towards carbon neutrality

A profound transition of energy system is central to China's"3060"goal since the bulk of anthropogenic emissions arises from energy use.Covering the production,conversion,transmission,distribution and consumption of energy,energy system has complex internal structure and close linkages with the surrounding economic and social systems.Energy system transition towards carbon neutrality has presented tremendous challenges in a wide range of aspects,including technology,finance market,business models,governance structure,policy regime,etc.A better understanding of the dynamics and mechanism underlying energy system transition is critical to the transition management of energy systems.

Special issue: Low-carbon management

This special issue of Frontiers of Engineering Management (FEM) targets at how to devise the strategies for lowcarbon management. Climate change is one of the greatest threats that mankind is facing today. Global cooperation has been undertaken to address climate change and establish the goal of controlling the surface temperature rise by no more than 2℃ or even 1.5 ℃ by the end of 2100. This has not only caused the establishment and development of the new international governance system, but also greatly promoted the revolutionary change of world's energy system toward low-carbon developme nt. Low-carb on management thus becomes an emergi ng megatrend.
