Today, October 24th, is Climate Protection Day. Sustainability is becoming a buzzword everywhere, and it will soon become a fundamental part of our daily lives. However, pollution of our planet remains a pressing issue and a huge challenge that we must address! INCON-LOGISTIC Kft. is working hard to make our company an environmentally friendly workplace that contributes to the protection of our planet.
This raises the question: where did this day originate? It was initiated by Bill McKibben, an American environmentalist and author, who founded the 350 international climate protection movement in March 2008. Climate Protection Day is tied to this movement, aiming to encourage people to take action for environmental protection and awareness. This day is observed in 192 countries around the world, including Hungary, in conjunction with the UN’s day, on October 24th, to draw attention to the urgent issue of climate change for policymakers.
In honor of Climate Protection Day, we’ve brought you an interesting topic! Have you seen electric trucks or buses on the roads? Or have you heard about hydrogen-powered vehicles? We want to discuss this in our article, as it’s a topic of great interest to us as well.
Alternative solutions
First, let’s take a look at alternative fuels, as many people still have doubts. This category includes hybrid vehicles, biofuels, and hydrogen propulsion, all of which are becoming increasingly important for sustainable transportation.
Starting with hybrid vehicles, which operate using a combination of traditional internal combustion engines and electric motors. These cars are not only ideal for reducing pollution but also offer more economical operation for users. Through regenerative braking and the optimization of the dual fuel system, hybrid vehicles save on fuel costs and improve air quality.
Biofuels, particularly biodiesel, also play a significant role in sustainable transportation. Biodiesel is produced from renewable sources, such as plants and animal fats, and emits fewer pollutants than traditional diesel. It can also be made from industrial and agricultural waste, further reducing the environmental footprint. A noteworthy alternative biofuel source is coffee grounds. With approximately 16,000 cups of coffee consumed globally every second, a vast amount of coffee grounds are generated, which can serve as an alternative source for biodiesel production. Researchers at Aston University aimed to produce high-quality biodiesel from residual coffee grounds using microalgae. This solution not only targets the recycling of coffee grounds but also contributes to the development of green energy sources. Biodiesel has numerous advantages: it is environmentally friendly, renewable, and versatile, as it can be used in existing diesel engines without modification. Promoting alternative fuels can help all of us contribute to sustainable transportation. It’s important to support biodiesel initiatives, advocate for renewable fuel use in our communities, and educate others about the benefits of sustainable energy. As the world moves increasingly towards sustainability, it’s essential for us to consciously choose the fuels and transportation solutions we use in our daily lives.
Why Are Electric Trucks Becoming More Popular?
The rise of electric trucks in urban transportation is increasingly important, especially for sustainable development and improving air quality. They do not emit harmful substances, such as nitrogen oxides, particulates, and carbon dioxide during operation, significantly contributing to better air quality compared to traditional diesel vehicles. Research from 2020 suggests that they can reduce air pollution in urban transportation by up to 90%. Additionally, electric vehicles are quieter than their internal combustion counterparts, helping to reduce noise pollution, particularly at night when traffic is minimal.
From an economic perspective, electric trucks are also more attractive, as their operating costs can be 30-50% lower than traditional vehicles. However, challenges such as the need for suitable charging infrastructure and the initial purchase costs pose obstacles to their wider adoption. Therefore, cities need strategies that support the use of electric vehicles.
The use of electric trucks in urban areas marks a significant step towards sustainable transportation, contributing to improved air quality and reduced noise pollution while also offering economic advantages.

How Does Hydrogen Propulsion Work?
Have you heard about this? It is one of the promising alternative fuel technologies for the future, which uses hydrogen as an energy carrier and is particularly attractive from a climate protection perspective. The environmental impacts of using hydrogen as a fuel are minimal, as hydrogen fuel cell vehicles produce only water vapor during operation, resulting in zero harmful emissions.
The core of the technology lies in fuel cell systems. The basic principle is quite simple: the structure consists of an elementary cell made up of two electrodes and a polymer membrane between them. The semi-permeable membrane allows only protons to pass through, causing hydrogen ions to accumulate around the cathode, where they react with oxygen ions. The electrons released at the anode exit the cell in the form of electric current, ultimately driving the electric motor that powers the vehicle.
Fuel cells require no maintenance and have a long lifespan. The elementary cell comprises just two electrodes and a membrane that is only permeable to positively charged hydrogen ions. The hydrogen ions (which are essentially positively charged protons due to the composition of hydrogen) form water molecules by reacting with oxygen from the air around the cathode. The separated electrons from the hydrogen molecules return to the cell from the electric motor powering the vehicle and are incorporated into the water molecules.
Unlike hybrids, hydrogen-powered fuel cell vehicles do not have an internal combustion engine. The energy needed for propulsion is generated from hydrogen stored in three high-pressure tanks located underneath the floor. The Toyota Mirai can hold a total of 5.6 kg of hydrogen; in comparison, a similarly performing all-electric vehicle would have a battery weighing around 700 pounds.
In Europe, hydrogen production is increasingly playing a significant role, especially with the utilization of renewable energy sources. In Puertollano, Spain, a solar park produces green hydrogen at the Iberdrola facility, which is used for various purposes, including fertilizer production.
In Germany, the HYBRIT consortium uses green hydrogen in steel production, while in France, several hydrogen production facilities are operating that also utilize renewable energy sources. The European Union aims to produce 10 million tons of renewable hydrogen by 2030 and import an additional 10 million tons, planning to invest over 22 billion euros to develop hydrogen production.
Hydrogen-Powered Buses: The Saviors of Cities
Sustainability in urban transportation is one of today’s major challenges, as the sight of streets filled with vehicles and the need to reduce air pollution demand new solutions. Whether we like it or not, the European Union has implemented various regulations aimed at environmental protection, requiring that 45% of newly sold buses be zero-emission vehicles. This percentage is set to increase to 65% by 2025. Additionally, by 2030, it is expected that CO2 emissions from buses and trucks will need to be reduced by 30%, as part of the fight against climate change.
This is where hydrogen-powered buses come into play, offering numerous advantages and the potential to revolutionize urban public transportation. Their introduction can significantly contribute to cleaner air and a more sustainable urban environment, addressing both pollution and the growing demand for efficient public transit solutions.
The greatest advantage of hydrogen buses is that they emit only water vapor during operation, as mentioned earlier. This is especially important in large cities, where air quality directly impacts the health of residents. Hydrogen-powered vehicles thus contribute to the fight for cleaner air.
These vehicles are not only environmentally friendly but also significantly quieter than conventional diesel buses. This characteristic enhances urban quality of life, as reduced noise pollution makes cities more livable. Additionally, thanks to the quick refueling of hydrogen buses, service providers can operate their fleets more efficiently, minimizing downtime. The range of hydrogen buses is also impressive, as they can travel longer distances than their battery-electric counterparts. This is particularly beneficial for longer routes, where traditional electric buses may face limitations. Furthermore, hydrogen can be produced from renewable energy sources, providing a sustainable solution in the long run.
Although we do not yet have precise data on the extent to which hydrogen-powered vehicles are used in public transport in various countries, the trend is clearly positive. There are already over 300 hydrogen buses operating across Europe, and this number continues to grow. In Germany, hydrogen-powered trains are in service, while France and the Netherlands are increasingly introducing more hydrogen buses into their fleets.
Interesting Fact:
The first major breakthrough occurred in the Far East. Japan was among the first countries in the world to launch its national hydrogen strategy as early as 2017. The country set ambitious goals, including establishing a supply chain capable of producing 300,000 tons of hydrogen by 2030 and ensuring broader access to hydrogen-based mobility. Plans include introducing 800,000 fuel cell vehicles and 1,200 fuel cell buses on the country’s roads by 2030.
