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.

Mobility is fundamental for the wealth and health of the world’s population, and it has a significant influence on our daily life. However, with the increasing complexity of traffic, the need to transport goods, and growing urbanization, improving the quality of mobility in terms of time, space, and air becomes more challenging. An autonomous electric vehicle offers technology and potential for new mobility concepts in smart cities. Today, many vehicles have been developed with automated driving capabilities. A safety driver is still required to intervene in most cases if the autonomous electric vehicle is not able to handle a situation in a safe and, at the same time, reliable way. One important aspect to achieve safety and reliability goals is a robust and efficient perception of the vehicle’s environment. The tragic accident involving an Uber self-driving car killing a pedestrian in 2018 highlighted the importance of perception in autonomous driving. In its investigation, the U.S. National Transportation Safety Board found that the Uber self-driving car and its safety driver involved in the accident failed to detect the pedestrian at the same time. Since this accident, the autonomous vehicle industry has been working to improve perception systems through the use of advanced sensors, machine learning algorithms, and other technologies. A variety of sensor technologies are used in vehicles to detect objects and perceive the vehicles’ surroundings. Cameras and radars are among the widely used technologies for sensing systems, as they are cheap and reliable, and as these sensors are operating at different wavelengths, they are not susceptible to common errors. While some companies solely use cameras and radars, others also use lidars in their sensing systems. These sensors are widely used in the industry, and the technology itself is continuously enhanced, leading to new developments, such as 4D lidar, which are capable of measuring not only the distance of an object but also its velocity by evaluating the phase shift of the returned light. Various methods for the perception of the environment exist and rely on different kinds of sensors. Machine learning-based methods have evolved rapidly in recent years and are currently leading the field in perception, particularly in the tasks of object detection and classification.

The exponential increase in Global greenhouse gas (GHG) emissions and the rapid depletion of fossil fuels over the past few decades have swayed the transportation sector toward becoming more electric. In the last decade, with continuous improvements in battery technology and interfacing power electronics, there has been immense progress in the electrification of land-based transport. As their electrification gains pace, the focus is shifting toward greening other forms of transport, such as maritime and aviation sectors, since they contribute substantially to the total carbon footprint. The marine sector has witnessed huge growth in recent years because of the development of international trade, wherein it plays an essential role in the transportation of goods across the globe. The variation in ship sizes, types, and routes—along with their grid-distant nature and water-borne operation—distinguishes them from terrestrial electric vehicles. This gives rise to a multitude of unique challenges on board as well as at the ports that they operate around. Power electronics is one of the key enabling technologies in tackling these challenges and thereby creating safe, reliable, and emission-free maritime transport.
