Electrofuels, also known as e-fuels, are electricity-based liquid fuels that can be used in internal combustion engines. E-fuels are made by using electricity to split water into hydrogen and oxygen, and then combining the hydrogen with carbon dioxide to make drop-in hydrocarbons like diesel, gas (methane), or jet fuel. While e-fuels can be low-carbon, they are not low-cost. The production of e-fuels is energy-intensive, and the equipment used to make them is expensive. As a result, e-fuels are significantly more expensive than fossil fuels and are not a realistic option for powering cars and trucks. However, e-fuels can be useful in sectors where electric batteries are not a viable option, such as aviation.

Premium fuel in EB improves performance and economy
Premium fuel can improve the performance and economy of EB engines. Using premium fuel in an EB engine can result in a notable increase in horsepower, with some estimates ranging from 7 to 20 horsepower. Additionally, premium fuel can also provide improved fuel economy, although the extent of the improvement varies depending on the vehicle. For example, the Honda CR-V experienced only a 1% improvement in fuel economy when using premium fuel, while other vehicles may see more significant gains.
The benefits of premium fuel in EB engines are attributed to its higher octane rating. Higher octane fuel has a higher knock threshold, allowing the engine controller to dial in more aggressive timing and higher boost pressures, which contribute to enhanced performance. Furthermore, premium fuel typically contains extra detergents that help keep the engine clean and carbon-free, which can also positively impact performance and fuel efficiency.
However, it is important to consider the cost-benefit analysis of using premium fuel. While premium fuel can provide performance and economy improvements, it comes at a higher cost per gallon. In some cases, the money saved by burning less gas due to improved fuel economy may not offset the higher cost of premium fuel. Therefore, the decision to use premium fuel in an EB engine should be based on the desired performance enhancement rather than solely economic considerations.
Additionally, it is worth noting that the benefits of premium fuel may vary depending on the specific vehicle and engine configuration. Some vehicles may exhibit negligible performance improvements when using premium fuel, while others may experience more noticeable gains. Therefore, it is advisable to refer to the vehicle's manual or seek advice from automotive experts or forums specific to the vehicle model to make an informed decision regarding the use of premium fuel in EB engines.
In conclusion, while premium fuel can indeed improve the performance and economy of EB engines, the decision to use it should take into account the specific vehicle characteristics, the desired level of performance enhancement, and the cost implications associated with the use of premium fuel over regular fuel.

EB fuel additives for gasoline and ethanol blends
Biobor EB is a fuel additive formulated for gasoline and ethanol blends. It is designed to combat the negative effects of ethanol in fuel tanks and engines, such as corrosion and phase separation, which can lead to costly repairs and breakdowns. By using Biobor EB, you can stabilise the fuel, prevent performance-robbing deposits and varnish, and protect vital engine components. This additive is suitable for use in any 2 or 4-cycle gasoline engine and can be applied through metered injection or splash blending with circulation.
Ethanol is a common additive in today's gasoline, added to raise octane and reduce the demand for refined hydrocarbons. However, ethanol is hygroscopic, attracting and accumulating water in your fuel tank. When ethanol blends with water, it can cause corrosion and engine damage, leading to a loss of engine efficiency and power.
Biobor EB is an effective solution to these issues. It prevents phase separation by keeping the gasoline and ethanol in suspension, stopping the formation of water and ethanol slugs that can destroy an engine. Additionally, it increases lubricity and cleans the entire fuel system, enhancing overall engine performance and efficiency.
To ensure the best results when using Biobor EB, it is important to remove any water or contamination from the fuel before applying the additive. For severely contaminated systems, consider fuel and tank cleaning. Biobor JF can also be used alongside Biobor EB to prevent microbial contamination.
By using Biobor EB, you can protect your engine and fuel system from the detrimental effects of ethanol, ensuring optimal performance, efficiency, and stability.

E-fuels as a death knell for ICE cars
E-fuels, also known as electrofuels, are electricity-based liquid fuels that can be used in internal combustion engines (ICE) such as cars. They are made by using electricity, preferably renewable, to split water into hydrogen and oxygen. The hydrogen is then combined with carbon dioxide to make drop-in hydrocarbons like diesel, gas (methane), or jet fuel. While e-fuels can be very low-carbon, they are not low-cost.
The production of e-fuels is energy-intensive and expensive. Using e-fuels in an ICE car requires about five times more renewable electricity than running a battery-electric vehicle. This makes e-fuels significantly more expensive than fossil fuels. According to a study by the International Council on Clean Transportation (ICCT), using e-fuels to reduce greenhouse gas (GHG) emissions from vehicles would cost three times as much as the penalty for not complying with Europe's fuel economy standards for passenger cars.
In addition, e-fuels are inherently inefficient. According to ICCT, an ICE on e-fuel only reaches an efficiency of 16%, compared to 72% for a battery-electric vehicle (BEV). This is because a significant amount of energy is lost in the conversion to liquid fuels and during combustion in internal combustion engines. In contrast, the majority of energy used by electric vehicles goes to powering the wheels, with only a small percentage lost in charging and by the motor.
While e-fuels can be used in existing ICE engines with minor adaptations, they are not a realistic option for powering all road transport vehicles. To power Europe's road transport fleet with liquid e-fuels, the EU would have to generate one and a half times more than its current total electricity production, and all of this electricity would have to be renewable. As a result, e-fuels are seen as a supplement to, rather than a replacement for, strong policy measures to reduce the impact of flying.
In conclusion, while e-fuels may provide a temporary solution for ICE cars, they are not a long-term alternative to electric vehicles. The high cost, inefficiency, and limited scalability of e-fuels make them impractical for widespread use in road transport. Therefore, e-fuels could indeed be considered a death knell for ICE cars, as they cannot realistically provide a pathway to decarbonize this sector.

Hydrogen fuel cells for cars
The hydrogen fuel cell technology offers several advantages. Firstly, it provides a quick refuelling experience, taking only about five minutes, similar to traditional gas stations. Secondly, these vehicles can offer a driving range of over 300 miles, comparable to conventional internal combustion engine cars. Additionally, HFCVs are equipped with regenerative braking systems, capturing and storing energy lost during braking in a battery, enhancing overall efficiency.
However, hydrogen fuel cells also face certain challenges. One significant issue is the variability in power demands during regular car usage, ranging from steady speeds on flat roads to intense acceleration for merging onto highways. While a steady power output suits hydrogen fuel cells best, manufacturers have addressed this issue by incorporating supplemental batteries similar to those in hybrid vehicles. These batteries provide extra power during acceleration and are recharged through regenerative braking or excess fuel-cell output.
Another challenge is the production of pure hydrogen, which requires a substantial amount of energy to extract from compounds like natural gas, with CO2 as a byproduct. Although hydrogen is the most abundant element in the universe, it is not typically found in its pure form. As a result, most hydrogen today is derived from fossil fuels, which can be counterproductive for decarbonisation efforts. Nevertheless, hydrogen fuel-cell vehicles present a promising path towards reducing carbon emissions, particularly in the aviation industry, where alternatives to conventional liquid fuels are limited.

E-fuels for aviation
E-fuels, also known as electrofuels, power-to-liquids, power-to-gas, e-gas, or "renewable synthetic fuels", are electricity-based liquid fuels that can be used in internal combustion engines. They are made from solar and wind energy. To produce e-fuels, electricity is used to split water into hydrogen and oxygen. The hydrogen is then combined with carbon dioxide to make drop-in hydrocarbons like diesel, gas (methane), or jet fuel.
While e-fuels can be very low-carbon, they are not low-cost. The equipment used to make e-fuels, such as electrolyzers, is expensive. Analysts have predicted that the cost of e-fuels will be around 3 or 4 Euros per liter in 2030.
The inefficiency and cost of e-fuels mean they are not a silver bullet for decarbonization. However, they could be a viable low-carbon fuel to meet part of aviation's future energy demands. Aviation currently accounts for about 6% of total petroleum consumption and 2-3% of global carbon emissions. As the demand for flights continues to increase, the use of e-fuels for aviation should be given serious consideration.
The EU's ReFuelEU Aviation regulation is a step towards the decarbonization of aviation and the promotion of synthetic fuels and renewable fuels. The regulation requires jet fuel suppliers in the EU to guarantee a blending of at least 2% sustainable aviation fuels (SAFs) in 2025, increasing to 6% in 2030 and 70% in 2050. The use of e-fuels in aviation is being pursued by several countries, including Norway, Germany, and France. However, the main obstacle to widespread e-fuel usage is their higher cost compared to fossil and bio-based fuels.
