Carbon Capture and Storage:History and the Road Ahead

The large-scale deployment of carbon capture and storage(CCS)is becoming increasingly urgent in the global path toward net zero emissions;however,global CCS deployment is significantly lagging behind its expected contribution to greenhouse gas emission reduction.Reviewing and learning from the examples and history of successful CCS practices in advanced countries will help other countries,including China,to promote and deploy CCS projects using scientific methods.This paper shows that the establishment of major science and technology CCS infrastructures in advanced countries has become the main source of CCS technological innovation,cost reduction,risk reduction,commercial promotion,and talent training in the development and demonstration of key CCS technologies.Sound development of CCS requires a transition from pilot-scale science and technology infrastructures to large-scale commercial infrastructures,in addition to incentive policies;otherwise,it will be difficult to overcome the technical barriers between small-scale demonstrations and the implementation of million-tonne-scale CCS and ten-million-tonne-scale CCS hubs.Geological CO_(2) storage is the ultimate goal of CCS projects and the driving force of CO_(2) capture.Further improving the accuracy of technologies for the measurement,monitoring,and verification(MMV)of CO_(2) storage capacity,emission reduction,and safety remains a problem for geological storage.CO_(2) storage in saline aquifers can better couple multiple carbon emission sources and is currently a priority direction for development.Reducing the energy consumption of lowconcentration CO_(2) capture and the depletion of chemical absorbents and improving the operational efficiency and stability of post-combustion CO_(2) capture systems have become the key constraints to largescale CCS deployment.Enhanced oil recovery(EOR)is also important in order for countries to maximize fossil fuel extraction instead of importing oil from less environmentally friendly oil-producing countries.

Exploring the frontiers of deep underground sciences and engineering—China Yunlong Lake Laboratory is striving to be the best

This paper introduces the establishment of deep underground infrastructure for science and engineering research.First,the representative deep underground research laboratories and facilities in the world and their functions were summarized and reviewed.Then,the plan and service target of China Yulong Lake Laboratory were proposed for the storage of resources and energy,as well as the sealing of hazardous waste in deep underground space.On this basis,this paper reveals how the facility addresses its key scientific issue on“The law of fluid matter migration in deep underground space”and engineering significance.Finally,the construction progress of the facility components was demonstrated in details.As is hoped,this paper would provide useful reference to the deep underground research community;meanwhile,international collaboration on deep underground research is highly welcome.

Evaluation of animal biosafety webinar series for professionals working in animal facilities across Pakistan during the COVID-19 pandemic

Experimental research with animals can help the prevention,cure,and alleviation of human ailments.Animal research facilities are critical for scientific advancement,but they can also pose a higher risk than other biomedical laboratories.Zoonosis,allergic reactions,bites,cuts,and scratches by animals are all substantial concerns that can occur in animal facilities.Furthermore,human error and unexpected animal behavior pose a risk not just to humans,but also to the environment and the animals themselves.The majority of biosafety and biosecurity training programs focus on clinical and biomedical laboratories dealing with human safety factors,with little emphasis on animal biosafety.The current virtual training was designed to improve biosafety and biosecurity capabilities of animal laboratory personnel,researchers,and veterinarians from different regions of Pakistan.The results revealed that understanding was improved regarding triggers for risk assessment in addition to annual and regular reviews(56%to 69%),biosecurity(21%to 50%),decontamination(17%to 35%),safe handling of sharps(21%to 35%),Dual Use Research of Concern(DURC)(17%to 40%),Personal Protective Equipment(PPE)usage by waste handlers(60.9%to 75%),waste management(56%to 85%),animal biosafety levels(40.57%to 45%),and good microbiological practices and procedures(17%to 35%).To bring human and animal laboratories up to the same level in terms of biosafety and biosecurity,it is critical to focus on areas that have been overlooked in the past.Training programs focusing on animal biosafety should be conducted more frequently to strengthen bio risk management systems in animal research facilities.
