What You'll Learn
Electric cars
While electric cars are costlier than pure internal combustion engine (ICE) cars, they are not more expensive than hybrid cars. The high cost of electric vehicles is largely due to the battery, which accounts for 35-40% of the total cost. However, battery prices are decreasing rapidly, and as they become more affordable, electric car prices will also become more competitive with gasoline cars.
Another factor influencing the adoption of electric cars is the availability of charging infrastructure. The demand for electric vehicles is increasing, and as a result, the charging infrastructure is also expanding. This is evident in India, where Tata recently signed an agreement for the installation of 17,500 chargers over the next two years.
Automakers are also working towards converting their offerings to all-electric vehicles. While some have committed to ending gasoline car sales by 2035, others may take until 2045-2050 to fully transition. Several states in the US have already passed laws or signed executive orders banning the sale of new gasoline passenger cars by 2035.
Despite the challenges and uncertainties, electric cars are undoubtedly the future. With advancements in technology, increasing consumer acceptance, and growing investments in electrification, the world is moving towards a carbon-neutral environment with electric vehicles playing a pivotal role.

Hydrogen fuel cells
HFCVs are considered zero-emission vehicles, as their only by-product is water vapour. However, they are much rarer than EVs. As of mid-2022, there were 17,000 or fewer hydrogen-powered vehicles on US roads, and these were all in California, the only state with a network of retail hydrogen fuelling stations. By contrast, almost three million EVs have been sold in the US. Since 2015, only three car companies have offered hydrogen-powered cars for sale: the Honda Clarity Fuel Cell, the Hyundai Nexo SUV, and the Toyota Mirai. However, Honda has now ended production of the Clarity, and Hyundai has sold only about 1600 Nexo SUVs in six years.
Despite their rarity, HFCVs have some advantages over EVs. They have a similar refuelling time to traditional gas stations, taking only five minutes to refuel. They also do not suffer from the same limitations as EVs when it comes to charging infrastructure, as they do not need to be charged and can instead refuel at hydrogen fuelling stations. This makes them more practical for long-distance travel and use in rural or remote areas, where charging stations for EVs may not be readily available.
The Government of India is betting big on hydrogen technology, and they see hydrogen as the future for commercial long-distance transportation. They plan to use electric vehicles for passenger cars and last-mile connectivity. However, hydrogen technology faces some challenges. One major obstacle is the availability of hydrogen fuel delivered at the required pressure of 10,000 psi. Without a reliable source of hydrogen fuel, HFCVs will not be able to function.

Synthetic fuel
One of the main advantages of synthetic fuel is that it can be used in regular combustion engine cars without any modifications to the engine, providing the same energy output as petrol. This makes it a more environmentally friendly option for classic car enthusiasts who wish to continue using their original engines. Synthetic fuel can also be transported and stored using existing infrastructure, giving it an advantage over electric vehicles (EVs) and making it a viable option for long-distance applications such as aviation and shipping.
However, the production of synthetic fuel requires a significant amount of energy, and there are concerns about the availability of sufficient energy and infrastructure to support large-scale production. Some also argue that burning synthetic fuel is still burning petrochemicals, which contributes to global warming. While synthetic fuel has the potential to reduce emissions compared to traditional gasoline or diesel fuels, it may not be as environmentally friendly as its supporters claim.
In terms of availability, synthetic fuel is currently a distant dream, with mass production not expected before 2030 due to the high cost of production. However, organisations such as Formula 1 have announced plans to use sustainable synthetic fuel from 2026 onwards, indicating a potential future for this type of fuel in high-performance applications.
Overall, synthetic fuel has the potential to be a less polluting alternative to traditional fossil fuels for combustion engine cars, but it faces challenges in terms of energy requirements and infrastructure, as well as competition from other alternative fuels and technologies such as EVs and hydrogen fuel cells.

Ammonia fuel
While electric vehicles (EVs) are becoming more popular, some people are still sceptical about them. One of the main concerns is the higher cost of production of electric cars compared to traditional cars. However, the cost of batteries is decreasing, which will make electric cars more affordable in the future.
In the meantime, some people are exploring alternative fuels. Ammonia is one such alternative. Ammonia fuel has been used in combustion engines before, but China's GAC has recently unveiled an engine that uses ammonia fuel for regular cars. While this is a step forward, there are still some concerns about using ammonia as a fuel.
Ammonia is toxic and can cause severe burns. There is also a risk of spills, which could result in hospitalizations. In addition, ammonia has a low energy density compared to diesel fuel, which means it may not be suitable for long-distance travel. Another concern is the release of nitrogen into the atmosphere during combustion, which can lead to the production of ammonia and ozone, causing acid rain.
Despite these challenges, ammonia fuel may be a viable option for certain industries. For example, it could be used in shipping and trucking, where the benefits of ammonia fuel may outweigh the risks. Additionally, ammonia is already used in agriculture, and solar power could be used to generate synthetic ammonia fuel. However, as BloombergNEF's head of transport and automotive analysis, Colin McKerracher, stated, "Ammonia is hellish to handle, I can't see it taking off in passenger cars."

Hybrids
Hybrid vehicles are a combination of electric and fuel-powered engines working in tandem. They are seen by some as a stop-gap arrangement in the transition to fully electric vehicles. Hybrids are currently more affordable than electric vehicles, which require costly batteries that make up 35-40% of their overall cost. However, as battery prices decrease, electric cars will likely become more affordable.
While electric vehicles are gaining popularity, they face challenges such as the lack of charging infrastructure, especially in rural and remote areas. Hybrids can utilise existing fuel infrastructure, making them more convenient for consumers. Additionally, the production of electric vehicles can be more costly, and the electricity grid may struggle to handle the increased demand from a widespread shift to electric cars.
In contrast, hybrids provide a balance by combining electric power with traditional fuel engines. This technology allows hybrids to have larger engines, which some consumers prefer. However, hybrids may still face challenges in the future. As classic car enthusiasts may know, the sale and use of classic cars, which are mostly fuel-powered, will still be allowed even after the shift to electric vehicles.
Despite the advantages of hybrids, some countries, like the UK, are focusing on ramping up the market share of electric vehicles. This shift is driven by government policies aiming for carbon neutrality and a reduction in pollution. However, the transition away from fossil fuels is a complex process, and it is challenging to meet the required increase in renewable energy sources to facilitate a complete shift to electric vehicles.
In conclusion, hybrids offer a balance between electric and fuel-powered engines, providing advantages such as utilising existing fuel infrastructure and combining it with electric power. However, with the push for carbon neutrality and the decreasing costs of electric vehicle batteries, the future may lean more towards electric vehicles, despite the challenges in the transition away from fossil fuels.
