AbstractFuel Cells are highly promising energy conversion systems for the new energy scenario. Particularly, Solid Oxide Fuel Cells (SOFCs) have been extensively studied during the last few years as a result of the increasing interest in the development of more efficient, and environmentally friendly ways of energy generation, as well as a consequence of their fuel flexibility. This work shows some strategies to improve the efficiency of SOFCs through the use of new anode materials, a novel method of microstructural optimisation by means of polymeric templates, using composites or cermets-based materials or applying a new concept in SOFC, e.g. the Symmetrical SOFC (SFC).

The United Arab Emirates (UAE) has been a major supplier of fossil fuel for the world economy for decades, which has allowed the country to thrive economically. But global concerns over ecological destruction and climate change is prompting the UAE’s leaders to pursue alternative sources of energy. From this ecological fear, Masdar City was born, an ambitious project that hopes to create the world’s first “zero-carbon” emission city. The project’s goal is to utilize energy in a socially, economically, and environmentally sustainable system without sacrificing modern lifestyles. This case study will utilize theory on energy and infrastructures to analyze the implications of the project’s innovations, as well as to explore the rising intersection of neoliberalism and environmentalism to understand how a project like Masdar came to be. In 2016, ten years after its initial construction, the city still had not achieved net zero-carbon emissions, but a mere 50%. The project’s ambitions included the creation of a new energy-based currency to account for consumption, and the integration of a massive data vault that stores all consumption of energy.What is found is a complex and highly integrated information system that could lead to the selling of information and the corporate/governmental manipulation of data for control over populations.

Systems engineering is a top-down approach to program management and systems procurement. It optimizes the development process by ensuring that the operational, technical, and cost goals (and limitations) of a total proposed system are understood before development begins. The requirements for the “forest” are determined before the features of the “trees” are specified. It makes a basic assumption that a team endeavor under single-system management will be established with authority to define development goals and assign subsystem programs and funding. It recognizes that each system requires a unique management structure that is based on the qualifications of the people and organizations available for the total endeavor. Systems engineering begins with an authoritative request or requirement for a system that would provide new capabilities or would reduce existing problems in a significant technical activity. After personnel and level of effort for a preliminary assessment of the need are identified, the initial effort then involves these steps: 1. A precise definition is prepared of the specific operational need for which the proposed system must provide a solution. For example, this book addresses the present national need for a new energy system that can provide a practical, timely, cost-effective, and nonpolluting alternative to petroleum-based fuels for transportation. The need arises from three factors: a. The perception that an alternative to dependence on petroleum fuels for transportation must be developed to avoid severe disruption of world economies in the early years of the twenty-first century; b. Evidence that combustion of fossil fuels is causing a significant increase in the carbon dioxide content of the atmosphere (if not reduced, this could eventually produce a “greenhouse effect,” leading to large-scale changes in climate and an increase in sea level, with severe economic consequences); and c. The belief that solar energy can be used via OTEC to supply nonpolluting fuel in sufficient quantity, at low enough cost, and in time to become a practical alternative to dwindling or unavailable petroleum supplies. Failure to define the system need with sufficient clarity is a root cause of most system development difficulties.

With a goal of achieving net-zero emissions by developing Smart Cities (SCs) and industrial decarbonization, there is a growing desire to decarbonize the renewable energy sector by accelerating green buildings (GBs) construction, electric vehicles (EVs), and ensuring long-term stability, with the expectation that emissions will need to be reduced by at least two thirds by 2035 and by at least 90% by 2050. Implementing GBs in urban areas and encouraging the use of EVs are cornerstones of transition towards SCs, and practical actions that governments can consider to help with improving the environment and develop SCs. This paper investigates different aspects of smart cities development and introduces new feasible indicators related to GBs and EVs in designing SCs, presenting existing barriers to smart cities development, and solutions to overcome them. The results demonstrate that feasible and achievable policies such as the development of the zero-energy, attention to design parameters, implementation of effective indicators for GBs and EVs, implementing strategies to reduce the cost of production of EVs whilst maintaining good quality standards, load management, and integrating EVs successfully into the electricity system, are important in smart cities development. Therefore, strategies to governments should consider the full dynamics and potential of socio-economic and climate change by implementing new energy policies on increasing investment in EVs, and GBs development by considering energy, energy, techno-economic, and environmental benefits.

I cannot overstate that 2020 was one of the toughest years on our industry’s ecosystem. The huge scale of the crisis wreaked by the COVID-19 pandemic has affected us all in such an unprecedented way and added a hard-hitting dimension to our industry’s fragile outlook. The prolonged periods of lockdown and the hiatus mandated in several countries, including some of the high-consuming ones, resulted in the largest oil glut ever, which exacerbated the economics severely. The flat oil-supply curve erased almost all the growth of the last decade and has put our endurance, agility, and resilience to a hard test. The offshore segment, from which approximately 33% of global oil production comes, was confronted by this turmoil, and escalating challenges surrounded the viability and sustainability of deepwater developments like never before. Unlike previous downturns experienced by our industry, the record plunge in oil demand has put the effectiveness of previous measures of recovery, such as deferral of investments or waiting for an upturn in oil prices, under the microscope. As the headwinds of the pandemic continue reshaping the global economy, our industry, and the deepwater segment in particular, have no time to lose to rock the boat and upend assumptions in the post-COVID-19 world. Imminent substantive changes within the industry are inevitable to reduce uncertainty and risk and to prepare for the new decade and beyond of delivery in light of the rapid evolution of renewables. Major deepwater operators have made remarkable achievements in lowering the average breakeven price to around $50 per barrel from around $70 per barrel in the past 5 years. Increasing cost savings are vital, and innovative money-saving engineering notions are an essential tactic to achieve a lower breakeven price. Additional proportionate, strategic, and reinventive initiatives are needed for the deepwater sector to adapt to the new energy landscape and search for new areas of growth. They will govern the future of the sector and differentiate the pioneers from followers. I am in no doubt that redefining fundamental strategies toward the development of partnerships in joint deepwater projects, embracing cutting-edge fit-for-purpose and cross technologies, and prioritizing net-zero emissions are keys to unlocking transformational gains and leveraging the opportunity to promote a sustainable future for the deepwater sector.
