Abstract The presence of impurities in captured CO2 plays a vital role in the safe and effective CO2 transport and storage in the CCUS chain. Impurities can significantly increase the cost of processing, transport, and storage and moreover add additional challenges to the design, operation, health and safety and integrity aspects. The effects of various impurities on the aforementioned challenges have been addressed in this work. Despite the importance of this area, there are still some knowledge gaps in terms of assessing the impact of CO2 specification on CCUS design and operations. International standards address different elements of the CCS chain, but none cover the full chain or consider the full chain economics. There are also differences between industry and leading CO2 authorities regarding the potential issues and challenges of implementing those standards. This paper reviews available standards and references which provide specifications/limitations for impurities for the purpose of transport and storage. In this work, the modified cubic EoSs and GERG EoS have been used to predict the thermodynamic properties and tuned viscosity models have been used for the prediction of transport properties. The required specifications for the quality of CO2 streams have been investigated using the above methodology for fluid properties, followed by the use of commercial software packages for thermohydraulic analysis of CO2 pipelines. Additionally, the storage capacity and geochemistry of fluids under high-pressure and high-temperature (HPHT) storage conditions were investigated. The impact of impurities has been assessed based on various CO2 sources using commercial capturing technologies. The assessment considered the impact of impurities on thermodynamic, thermohydraulic, integrity and operation of CO2 transport, injection, and storage system. This would include the effects of various types of components and their typical concentrations, e.g., water content, non-condensable gases (N2, O2, CH4, Ar, H2and CO), toxic gases (H2S and SO2), and hydrocarbons, on the thermophysical properties including density, viscosity, phase envelope and hydraulic parameters. A comparison of modelling results against the available experimental data measured at elevated pressure and temperature conditions have also been presented. This paper has mainly focused on the lessons learned from past CO2 transport design and operational experiences in order to identify the areas where it could lead to an optimised system in terms of design, costs, and operation. Additionally, past experience in the design of CO2 pipelines and operation of CO2 injection has been used to identify opportunities where CO2 specifications and guidelines could potentially be modified in order to achieve an optimised and cost-effective CO2 transport and injection system.

The Impact

Battery energy storage systems (BESSs) are being deployed on electrical grids in significant numbers to provide fast-response services. These systems are normally procured by the end user, such as a utility grid owner or independent power producer. This paper introduces a novel research project in which a research institution has purchased a 1 MW BESS and turned ownership over to a utility company under an agreement that allowed the institution to perform experimentation and data collection on the grid for a multi-year period. This arrangement, along with protocols governing experimentation, has created a unique research opportunity to actively and systematically test the impact of a BESS on a live island grid. The 2012 installation and commissioning of the BESS was facilitated by a partnership between the Hawaii Natural Energy Institute (HNEI) and the utility owner, the Hawaiian Electric and Light Company (HELCO). After the test period ended, HELCO continued to allow data collection (including health testing). In 2018, after 8500 equivalent cycles, the BESS continues to operate within specifications. HNEI continues to provide HELCO with expertise to aid with diagnostics as needed. Details about the BESS design, installation, experimental protocols, initial results, and lessons learned are presented in this paper.

Most experts would agree that recovery from the COVID-19 crisis will be slow (see Figure 6.2), in large part due to the impact that the crisis has had on the global travel and tourism industry (Romei, 2020). Until there is vaccine, the virus will influence nearly every sector of travel from transportation, destination and resorts, to the accommodations, attractions, events and restaurants. The first section of this chapter looks at the future for these different sectors, a future heavily influenced by technology and a heightened emphasis on health and safety. The second part of the chapter focuses on a theme that has been prevalent in this book – the need for adaptability or ‘COVID-aptability’. Consumer demands and behavior will be permanently altered by the pandemic, and all stakeholders in the travel industry will need to adapt. One part of adaptability is redesigning servicescapes – a necessity for many after the lockdown, and this is the subject of the penultimate section of the chapter. The conclusion looks at lessons learned from this crisis.

ABSTRACT Introduction At the start of the coronavirus disease 2019 (COVID-19) pandemic, Walter Reed Army Institute of Research (WRAIR) mobilized to rapidly conduct medical research to detect, prevent, and treat the disease in order to minimize the impact of the pandemic on the health and readiness of U.S. Forces. WRAIR’s major efforts included the development of the Department of Defense (DoD) COVID-19 vaccine candidate, researching novel drug therapies and monoclonal antibodies, refining and scaling-up diagnostic capabilities, evaluating the impact of viral diversity, assessing the behavioral health of Soldiers, supporting U.S. DoD operational forces overseas, and providing myriad assistance to allied nations. WRAIR personnel have also filled key roles within the whole of government response to the pandemic. WRAIR had to overcome major pandemic-related operational challenges in order to quickly execute a multimillion-dollar portfolio of COVID-19 research. Consequently, the organization learned lessons that could benefit other leaders of medical research organizations preparing for the next pandemic. Materials and Methods We identified lessons learned using a qualitative thematic analysis of 76 observation/recommendation pairs from across the organization. These lessons learned were organized under the Army’s four pillars of readiness (staffing, training, equipping, and leadership development). To this framework, we added organizing and leading to best capture our experiences within the context of pandemic response. Results The major lessons learned for organizing were: (1) the pandemic created a need to rapidly pivot to new scientific priorities; (2) necessary health and safety precautions disrupted the flow of normal science and put programs at risk of missing milestones; (3) relationships with partners and allies facilitated medical diplomacy and advancement of U.S. national military and economic goals; and (4) a successful response required interoperability within and across multiple organizations. For equipping: (1) existing infrastructure lacked sufficient capacity and technical capability to allow immediate countermeasure development; (2) critical supply chains were strained; and (3) critical information system function and capacity were suddenly insufficient under maximum remote work. For staffing and training: (1) successful telework required rapid shifts in management, engagement, and accountability methods; and (2) organizational policies and processes had to adapt quickly to support remote staffing. For leading and leadership development (1) engaged, hopeful, and empathetic leadership made a difference; and (2) the workforce benefitted from concerted leadership communication that created a shared understanding of shifting priorities as well as new processes and procedures. Conclusions An effective pandemic response requires comprehensive institutional preparedness that facilitates flexibility and surge capacity. The single most important action leaders of medical research organizations can take to prepare for the next pandemic is to develop a quick-reaction force that would activate under prespecified criteria to manage reprioritization of all science and support activities to address pandemic response priorities at the velocity of relevance.

The Impact

The coronavirus outbreak has created a global health crisis that has disrupted all industries, including the construction industry. Following the onset of the pandemic, construction workers faced and continue to face unprecedented safety and health challenges. Therefore, construction employers established new safety precautions to protect the health and safety of the workforce and minimize the spread of the virus. The new precautions followed the advice and guidelines offered by different health and safety agencies like the Occupational Safety and Health Administration (OSHA), Centers of Disease Control and Prevention (CDC), and the Associated General Contractors of America (AGC). With construction projects resuming operations, it becomes important to analyze the coronavirus-related health and safety concerns of construction workforce and understand how the new safety procedures can assist on jobsites. Existing studies mostly focused on interviews and surveys with construction companies to understand the impact on project performance and supply chains. However, no study has yet to analyze the United States construction workforce. This paper fills the gap by providing a qualitative descriptive analysis of the COVID-19 complaints data gathered by OSHA from construction jobsites. Information gathered by OSHA includes the jobsite location, the North American Industry Classification System (NAICS) of the construction company, the type of the complaint (i.e., formal or non-formal), and a thorough description of the complaint. N-grams were employed to analyze the complaints, detect trends, and compile a list of the most frequent concerns reported by the workforce. The analysis of the complaints data identifies safety practices that were most violated, highlights major safety and health concerns for construction workers, and pinpoints geographical areas that have seen a surge in complaints. The study also synthesized the existing research corpus and compiled a list of 100 best practices that construction employers can adopt to mitigate the concerns of the workforce. The findings of this study provide insights into the safety and health trends on construction sites, lay the foundation for future work of academicians and practitioners to address the concerns faced by construction workers, and serve as lessons learned for the industry in the case of any future pandemic.

Purpose This study aims to find and evaluate the impact of COVID-19 in India’s mining activities. From the literature survey and input from experts, 14 important factors and ten green recovery strategies are identified. These 14 factors and 10 strategies are examined in a real industrial environment. Design/methodology/approach In this research study, fuzzy-complex proportional assessment is used to compare the identified strategies with the selected factors. Based on the outcome, this study identifies the optimum strategy that could assist the mining industry in handling both COVID-19 and sustainability issues. Findings The study’s outcome reveals that a large group of workers, collapse of demand and disruption, and suffered contractual workers are the top three factors that need to be considered regarding COVID-19 and sustainability issues. Effective strategies for eco-innovation practices, an emphasis on health and safety, and environmental awareness, education and training are the three primary strategies to be implemented for the greatest impact. Originality/value This research study is the first of its kind to coordinate both issues of COVID-19 and sustainability. In this regard, this study sheds a timely light on the precautions that need to be taken in tackling COVID-19 and sustainability issues. This study’s outcome will enhance the managerial capability in developing robust and effective strategies for handling difficult situations.

Product dissection has been used successfully in a variety of ways to actively engage students in their learning; however, using product dissection in the classroom does have drawbacks: products, tools, and their upkeep can be costly, workspace and storage space can be difficult to obtain, and even the best crafted dissection assignments can end in chaos. Recent cyberinfrastructure initiatives seek to create ubiquitous, comprehensive, interactive, and functionally complete digital environments for research communities that consist of people, data, information, tools, and instruments. With product dissection as our unifying theme, we are applying cyberinfrastructure tools and technologies to undergraduate engineering education and assessing the impact of these tools on student learning. Specifically, the project combines product dissection activities at three universities with two digital design repositories CAD modeling and animation, video, and MediaWiki technology to enable cyberinfrastructure-based product dissection activities. Lessons learned from these efforts are presented from the students’ perspectives as well as that of the faculties in both engineering and computer science. The implications for implementing the developments on a national scale are discussed along with ongoing research.

Due to significant temperature differences between the injected medium and in situ formation, injection of CO2 (as with water or other cold fluids) at depth induces thermal changes that must be accounted for a complete understanding of the mechanical integrity of the injection/storage system. Based on evaluations for the Northern Lights Carbon Capture and Storage (CCS) project, we focus on thermal effects induced on the caprock via conduction from cooling in the storage sands below. We investigate, using both analytical and numerical approaches, how undrained effects within the low permeability caprock can lead to volumetric contraction differences between the rock framework and the pore fluid which induce both stress and pore pressure changes that must be properly quantified. We show that such undrained effects, while inducing a more complicated response in the stress changes in the caprock, do not necessarily lead to unfavourable tensile conditions, and may, in fact, lead to increases in effective stress. These observations build confidence in the integrity of the caprock/seal system. We also show, through conservative assumptions, that pressure communication between the caprock and storage sands may lead to a localised negative effective stress condition, challenging stability of the base caprock, which will be mitigated for in field development planning.
