As a"bridge energy"to assist China's energy system's transition,natural gas serves as a"fundamental,flexible,and integrated"component of the country's energy system.In addition to being a key component in the low-carbon transformation of fossil fuels,hydrogen energy is also a key means of addressing the issues of new energy consumption and peak shaving.Natural gas and hydrogen energy have similar chain characteristics,as well as similar storage and transportation properties.They also share some application domains.So,they have favorable growth conditions to create a"natural gas + hydrogen energy"comprehensive industry chain.The primary roles that hydrogen energy and natural gas play in the new energy system provide the foundation for this article's exploration and evaluation of the necessity and feasibility of the"natural gas + hydrogen energy"coupling to create an entire industry chain.The analysis in this article focuses on the direction of development of the entire industry chain in terms of upstream preparation,midstream storage and transportation,and downstream utilization.Finally,specific operational recommendations are presented from the viewpoints of policy support,demonstration application,and technical research.
In recent years,improper plastics management has produced major environmental issues.As the world comes to an agreement on plastic pollution prevention,significant worldwide petrochemical and chemical businesses have devoted themselves to the plastic recycling industry.Studying and learning from their plastic recycling development strategies is of great significance to the sustainable development of the plastics business of Chinese chemical companies.This paper examines BASF,ExxonMobil,SABIC,and SK's plastic recycling development plans and pathways,and makes four recommendations:strengthening the responsibility mechanism and actively participating in the development of a plastic circular economy;improving goal orientation and defining clear recycling targets;advancing technological research with emphasis on the driving role of recycling technology;and increasing open cooperation and building a whole life industrial recycling chain of plastics.
A finance company functions as a type of"internal bank"that is commonly used by state-owned central enterprises to manage finance.An efficient financial platform of an enterprise's industrial chain,it helps to increase capital efficiency,lower financing costs,expand business,and guarantee capital security through a variety of activities such as fund settlement,fund collection,credit,and bill discounting.It does,however,have certain shortcomings.This paper seeks to clarify the finance companies'existing problems while outlining their current state of development.The problems include contradictions between the emphasis on business stability and significant financial risks,the original efficiency model and more stringent regulations,and the effectiveness of financial services and insufficient information support.This paper also examines the business development direction of the finance companies and makes suggestions based on the typical practices of the finance companies of CNPC and China Power International Development Limited.The suggestions include:strengthening the risk supervision system to guarantee that companies are run legally;closely adhering to national policy guidelines,emphasizing primary responsibilities and businesses while developing creatively;quickening the pace of digital transformation and upgrading,and raising the standard of technology in financial services.
A new,large-scale,long-term energy storage technology that has emerged quickly in China in recent years is compressed gas energy storage.Two popular working media for compressed gas energy storage are CO2 and air.After analyzing the basic technological pathways of compressed gas energy storage,this papers concentrates on adiabatic compressed gas energy storage,evaluates its system structure and performance,and focuses on the influencing elements of cycle efficiency.It also chooses an object that is representative of different systems and examines their investment costs and LCOE.Lastly,it talks about the growth trend of compressed gas energy storage and concludes that the development paths of compressed air(CO2)energy storage and liquid air(CO2)energy storage are distinct.According to the paper,the technology of advanced adiabatic compressed air energy storage has reached a mature state,with the efficiency of 100 MW or more having gradually surpassed that of pumped storage.And its unit investment cost and whole-life LCOE have started to surpass that of pumped storage of the same scale.The paper therefore suggests bolstering policy support and upgrading industrial supporting infrastructure,in order to quickly establish industrial advantages.On the other hand,the paper notes that although having significant development potential,compressed CO2 and liquid air(CO2)energy storage technologies are currently in their infancy due to high investment and LCOE costs.So,in order to promote the creation of demonstration projects,the paper recommends improving industry,academic,and research integration,putting policies in place that support grid connection and power pricing,and taking immediate action to improve technology maturity.
