The Island Hydrogen Project: Electrolytic Generated Hydrogen for Automotive and Maritime Applications
In 2014, the transport sector was responsible for 23% of total greenhouse gas emissions in the European Union (EU). During the same year, 13% of that sector’s emissions came from the maritime segment, a number that is expected to rise during the coming years. The transport sector’s share of renewable energy in 2014 was just 5.9%, mostly comprising biodiesel and bioethanol fuel.Electrification is a solution that will help reduce the transport sector’s reliance on hydrocarbonbased fuels. This article describes the Island Hydrogen project, which introduced and tested new solutions to produce and use hydrogen as a fuel for vehicles and vessels.

Green Gas to Replace SF6 in Electrical Grids
Environmental considerations are increasingly taking a front seat in all arenas of our daily lives—political, industrial and societal. Not least among the major concerns are global warming and the greenhouse gases that contribute to it, as their concentration in the air reaches new heights. Hence the power industry’s focus on sulfur hexafluoride (SF6) and the need to find a suitable alternative for it in industrial applications. Grid Solutions, a GE and Alstom joint venture, has identified a fluoronitrile based gas mixture dubbed ‘g3–green gas for grid’ that is such a alternative.

IoT-Enabled Humans in the Loop for Energy Management Systems: Promoting Building Occupants’ Participation in Optimizing Energy Consumption
The governments of various countries continue to be alarmed by the adverse environmental impact of fossil energy, which could result in additional pollution, polar glaciers further melting, and intensified natural disasters. Around the world, the consumption of fossil energy is a socioeconomic and sociopolitical calamity. However, remedies in such circumstances depend, to a great extent, on the availability of cleaner energy resources and governmental policies on energy pricing, consumption, and conservation. Consequently, corrective countermeasures and effective policies are essential to cope with energy production and consumption.

Deploying Electric Vehicles Into Shared-Use Services: Amping up Public Charging Demand to Justify an Investment in Infrastructure
This past October, the Intergovernmental Panel on Climate Change released a special report, “Global Warming of 1.5?C: A Summary for Policymakers.” A total of 91 authors and review editors from 40 countries worked on the report, basing their projections and conclusions on peer reviews and the more than 6,000 studies they examined. Lobbying by low-lying island states and others who were concerned that the assumptions and agreements from the Paris Climate Change Conference and Treaty might not be aggressive enough prompted the report’s creation.

Powerlines and Wildfires: Overview, Perspectives, and Climate Change: Could There Be More Electricity Blackouts in the Future?
Overhead powerlines cross extensive areas of forest and grasslands, and these areas are often flammable and can burn. Wildfire is a natural phenomenon important to many ecosystems around the globe, but also capable of considerable damage to people and communities. As a result of human activity in natural spaces, people have altered wildfire regimes over time, and wildfires have become a threat to people, to their property, and infrastructure.

Obstacles to the Success of Fuel-Cell Electric Vehicles: Are They Truly Impossible to Overcome?
Cities with substantial population growth continue to encounter economic, social, and environmental challenges in their daily operations. This growth has led to public outcry demanding that societies curb their dependence on fossil fuel consumption to limit global warming. In fact, major cities’ usage of fossil fuels constitutes 75% of global energy resource use and accounts for 70% of global greenhouse gas emissions, despite occupying only approximately 5% of the planet’s total land mass. Rapid urbanization also contributes to multiple types of serious environmental pollutants (e.g., air, soil, and water), which affect the people’s health and the quality of life.

Smart Cities for a Sustainable Urbanization: Illuminating the Need for Establishing Smart Urban Infrastructures
Cities with substantial population growth continue to encounter economic, social, and environmental challenges in their daily operations. Figure 1 shows how the urban population, in which more than 55% of the globe’s people currently live, has nearly quadrupled since the 1950s. Globally, urbanization is expected to encompass 70% of the world population by 2050, resulting in an unprecedented increase in the consumption of existing resources.

Data-Driven Dynamical Control for Bottom-up Energy Internet System
With the increasing concern on climate change and global warming, the reduction of carbon emission becomes an important topic in many aspects of human society. The development of energy Internet (EI) makes it possible to achieve better utilization of distributed renewable energy sources with the power sharing functionality introduced by energy routers (ERs). In this paper, a bottom-up EI architecture is designed, and a novel data-driven dynamical control strategy is proposed.

DAFT-E: Feature-Based Multivariate and Multi-Step-Ahead Wind Power Forecasting
At the recent 26th United Nations Climate Change Conference last year, more than 140 countries pledged to achieve net-zero emissions to combat climate change. And in a dramatic appeal to attain sustainability in the skies, Europe’s Flightpath 2050 initiated a bold effort to reduce CO2 emissions worldwide by 75%, NOx emissions by 90%, and the noise footprint by 60% by the midcentury mark.

Advancements in Clean Air Insulation Technologies for Switchgear and Circuit Breakers
Our power systems and grids are rapidly transforming to help realize a CO2 -neutral world. Reducing CO2 and equivalent greenhouse gases (GHG) is an important step to address global warming. Power systems must phase out the most potent GHG, sulfur hexafluoride (SF6 ), to achieve this CO2 -neutral society. SF6 has the highest known global warming potential (GWP) of all GHG, estimated to remain in the atmospheric environment for 3,200 years. There is also no SF6 gas waste management system commercially available today. At the same time, utilities must ensure transmission performance and reliability are maintained or increased.
