As the penetration of complex software-driven inverter-based resources (IBRs) rapidly increases in power systems around the world, the need for modeling large areas of these systems in a time-domain electromagnetic transient (EMT) environment has also increased. Since 2016, the Australian Energy Market Operator (AEMO) has been developing “large-scale” EMT models of parts of Australia’s interconnected Eastern Australian power system, known as the National Electricity Market ( NEM ), for use across many of AEMO’s functions as the NEM’s independent system operator. Due to the size and complexity of the models, these simulations have required large computational requirements and were typically very slow, taking more than 24 h for a 30-s simulation in 2016.

I Started infrastructure Masons (iMasons) in 2016 to unite the builders of the digital age. How to define digital infrastructure is an ongoing discussion, as are questions about the size of the digital infrastructure industry. The answers to these questions are essential to answer one more: What is the industry’s carbon footprint? The answer to that question will serve as a baseline for the iMasons Climate Accord, which launched on 25 April 2022, and commits member companies to achieve carbon neutrality in power, materials, and products as a step toward net zero. To measure our industry’s carbon footprint, we need to define two things: what to measure and how to measure it.

The notion of global south can be defined as a term that broadens the concept of developing countries, referring to those countries that have a social and economic structure with great inequalities in the quality of life levels of their populations. Generally, in these countries, access to basic resources is scarce, and this does not allow the equitable growth and empowerment of these communities.

Technology for the electrification of transport is currently undergoing rapid development that is necessary for reducing greenhouse gas (GHG) emissions. On a global level, the transport sector is responsible for around 12% of the world’s GHG emissions. While the introduction of battery-electric cars is leading the way in terms of commercial scale, developments are also progressing toward electrification of heavy-duty vehicles for road freight transport and coastal transport by battery-electric ships. The performance of modern Li-ion batteries is also enabling electrification of other types of machines and small vehicles that have traditionally been powered by internal combustion engines (ICEs). However, until recently, the developments toward electrification have been mainly directed toward applications with either a large market for series-produced vehicles, such as electric cars, or a high degree of individual engineering for each unit, such as battery-electric ships. Still, there are several application areas where other types of vehicles and machines contribute significantly to GHG emissions.

Highlighted by the United Nations sustainable Development Goals to ensure universal access to clean, reliable, and modern energy services by 2030, the world is increasingly becoming concerned by energy poverty and its consequences on human development and the environment. Yet, even if numerous initiatives and a significant amount of money are directly addressed to tackle the energy-access challenges, a billion people are still denied access to basic and modern electricity services, especially in rural areas of sub-Saharan Africa and Southeast Asia. In the past two decades, the African continent has seen an encouraging improvement as the number of people gaining access to electricity rose from 9 million per year between 2000 and 2013 to 20 million per year between 2014 and 2019, outpacing population growth for the first time. However, most of those recent improvements are restricted mainly to urban and peri-urban areas of a small number of countries located in eastern or western Africa. Also, the population without access to electricity in Africa is expected to increase in the coming years following the health crisis and economic downturn caused by COVID-19. This definitely proves the fragility and poor resilience of the electrification solutions favored today. While grid extension and conventional microgrids suffer from low inclusivity and replicability, solar home systems are only a stopgap measure and fail to boost socioeconomic development. A third way must be proposed to combine quick and affordable access to basic electricity services and community uplift through socioeconomic development, answering the two greatest challenges that developing countries are struggling to cope with today. With this objective in mind, Nanoé, a French–Malagasy social company, is developing the lateral electrification model, based on the collaborative and progressing building of electric infrastructures, which is presented in this article, first from a general point of view and then through a focus on Nanoé’s experience in Madagascar.

Electric Vehicle (EV) sales and adoption have seen a significant growth in recent years, thanks to advancements and cost reduction in lithium-ion battery technology, attractive performance of EVs, governments’ incentives, and the push to reduce greenhouse gases and pollutants. In this article, we will explore the progress in lithium-ion batteries and their future potential in terms of energy density, life, safety, and extreme fast charge. We will also discuss material sourcing, supply chain, and end-of-life-cycle management as they have become important considerations in the ecosystem of batteries for the sustained growth and adoption of EVs. With significant government and private sector investments in research and development, processing, and manufacturing and advances in anodes (lithium and silicon), cathodes (high nickel), designs, supply chain development, and the circularity of lithium-ion batteries, lithium-based batteries are on track to make EVs mainstream, addressing climate concerns of fossil-fueled vehicles.
