This commitment is reflected in policies to encourage and support the adoption of zero-emission vehicles. However, despite growing demand and carmakers' efforts to expand the range of electric vehicles available on the market, there are still obstacles to overcome. At the same time, there is growing interest in innovation in the battery sector, with the search for solutions that can improve range, reduce charging times and cut production costs.
Obstacles and prospects for the electric vehicle market
Despite the potential of electric vehicles, the industry faces several challenges in the future. Advances in EV technologies such as batteries, expansion of charging infrastructure and cost reduction are key factors in ensuring greater EV adoption. In addition, the integration of emerging technologies such as autonomous vehicles and hydrogen fuel cells could further transform the market, offering innovative solutions to mobility challenges. To meet these challenges, governments, industries and organizations will need to make continuous efforts to encourage innovation and accelerate the transition to more sustainable mobility.
Key innovations for the future
Several technologies are set to revolutionize the electric vehicle market:
- the lithium-sulfur battery ;
- induction charging ;
- autonomous vehicles;
- hydrogen fuel cells as an alternative to electric vehicles;
- the Hyperloop
Let's explore one technology at a time to better understand the benefits it will bring.
1. Lithium-sulfur battery
Lithium-sulfur batteries have a long history dating back to the 1960s, and although they have evolved into systems with significantly improved performance, they still fail to meet the needs of practical applications. Over the past decade, to overcome these barriers to widespread adoption, research efforts have progressively improved the fundamental understanding of electrochemistry by proposing innovative new approaches to materials and cell design.
We examine the advantages and disadvantages of using solid electrolytes in the assembly of lithium-sulfur (Li-S) batteries, which are solid-state batteries (ASSLBs).
Advantages:
- High specific energy: lithium-sulfur batteries offer significantly higher specific energy, on the order of 550 Wh/kg. Lithium-ion batteries, on the other hand, rarely exceed 260 Wh/kg.
- Relative lightness.
Disadvantages:
- Structural changes to electrodes: during the charging and discharging cycle, structural changes occur in the electrodes, which can lead to mechanical stresses inside the battery.
- Consumption of internal materials: due to the charging and discharging processes, the battery's internal materials undergo progressive consumption.
- Problems hindering large-scale commercialization: safety, durability and performance stability over time are just a few.
2. Induction charging
Wireless charging technology for electric cars is based on the use of polyphase electromagnetic coupling coils with rotating magnetic fields. This system enables energy to be transferred from the grid to the car's battery without the need for physical cables. The coils are designed to be compact, guaranteeing higher magnetic density and energy transfer power of up to 100 kW with 96% efficiency.
Operation is very simple: once positioned on the inductive plate, the vehicle equipped with an inductive receiver receives energy via the magnetic field generated by the charging coil. This process takes place quickly and safely, enabling efficient recharging without the need for physical connections.
Advantages and disadvantages
Advantages:
- the added convenience of wireless charging.
- the ability to recharge while driving. It offers increased autonomy and greater flexibility during journeys.
Disadvantages:
- Initial installation cost.
- The need to integrate inductive coils into both the vehicle and the road infrastructure.
The first road trials of wireless charging have already been successfully completed, demonstrating the potential of this technology. For example, an experimental wireless charging system has been installed along the A35 Brebemi freeway, integrated into the asphalt layer. This project, the fruit of collaboration between several companies and institutions, has produced promising results and attracted the interest of the automotive industry.
3. Autonomous vehicles
Autonomous vehicles, also known as "self-driving cars", represent a major innovation in the automotive industry, revolutionizing the way we think about mobility on the road. This technology relies on the use of a range of sensors, such as cameras, radar and lidar, as well as sophisticated software and algorithms, to enable vehicles to operate autonomously, without the need for direct human intervention.
Advantages and disadvantages
Autonomous vehicles offer a number of advantages:
- Increased road safety: by reducing human error in driving, they can help prevent road accidents.
- Improved traffic management.
- Accessibility and inclusion: offering greater independence to people with reduced mobility or those unable to drive conventional vehicles.
- Reduced environmental impact.
However, there are also disadvantages to consider, including
- High development and production costs.
- Legal and insurance liability.
- Ethical aspects.
- Risk of hacking and privacy breaches: they can be vulnerable to cyber-attacks and raise concerns about privacy and personal data protection.
4. Hydrogen fuel cells
Fuel cell cars represent a revolutionary prospect for the automotive industry. They use a technology that exploits an electrochemical reaction between hydrogen and oxygen to produce electricity, powering an electric motor. This process produces only water vapor as a by-product, making hydrogen-powered cars "zero-emission" vehicles.
Advantages:
- No emissions while driving.
- Access to restricted traffic zones and tax benefits.
- Rapid refuelling similar to that of a petrol/diesel car.
Disadvantages:
- Limited refueling infrastructure: currently, the network of hydrogen refueling stations is still underdeveloped, especially when compared with the wider availability of electric car charging stations or gasoline/diesel stations.
- High cost of hydrogen.
- Limited availability and high cost of hydrogen car models.
Currently, only two hydrogen car models are available on the European market: the Hyundai Nexo and the Toyota Mirai. However, the limited network of refuelling stations in Italy, with only 36 projects under development between now and 2026, still represents a major challenge to the widespread adoption of hydrogen-powered cars.
5. Hyperloop
Hyperloop is a high-speed transportation concept that uses a system of partially empty tubes to transport goods and passengers at speeds comparable to those of jet aircraft, but at considerably reduced costs. The technology involves the use of magnetic systems to propel the capsules inside the tubes, eliminating air resistance and enabling very high-speed travel.
Advantages:
- High speed: Hyperloop promises speeds of up to 1223.1 km/h, enabling rapid travel between distant cities in much less time than conventional means of transport such as high-speed trains or planes.
- Cost reduction: Due to its energy efficiency and ability to use existing infrastructure such as highways, Hyperloop could offer lower travel costs than other long-distance transport options.
- Environmental sustainability: Because Hyperloop operates on the principles of electricity and magnetism, it can be powered by renewable energy sources, reducing environmental impact and greenhouse gas emissions compared with traditional means of transport.
Disadvantages:
- High construction costs: building a network of suspended tubes and service stations for Hyperloop requires a significant initial investment, which could be prohibitive for many governments and investors.
- Safety and reliability testing: given the innovative nature of Hyperloop technology, extensive testing is required to guarantee the system's safety and reliability, especially considering the extreme speed at which capsules travel in the tubes.
- Technological and regulatory constraints: The introduction of Hyperloop requires the development of new regulations and safety standards, as well as the overcoming of potential technological hurdles related to the system's design and maintenance.
Hyperloop represents a promising alternative to traditional means of transport, with the potential to radically transform long-distance travel. However, a number of technological, financial and regulatory hurdles need to be overcome before Hyperloop becomes a large-scale reality.
In conclusion
We have seen that these five technologies that will revolutionize the electric vehicle market by 2030 are different from one another. Their development will be constant, and we'll soon see changes in the market as they become more widespread.
