From record breaking heatwaves to sporadic weather conditions, it can seem that nature is looking for some retribution against humans for their contributions to climate change. Scientists have issued a series of warnings to the drastic consequences if carbon emissions are not reduced with more ecologically friendly energy sources.
Buses That Run on Formic Acid
A group of students from the Technical University of Eindhoven in the Netherlands has developed a bus that works with formic acid. This acid, a natural substance produced by ants and bees, is a more economical, practical and, of course, much cleaner and sustainable energy source than traditional fuels commonly used today.
Although it is possible to find it in nature, formic acid can also be obtained at the industrial level. It is currently used to process textile and leather materials, to keep food for livestock and to manufacture cleaning products.
Hydrocin: The Fuel of Future Buses
The new fuel, called “hydrocin”, is in a liquid state, which facilitates transport and loading on buses. The group of students is responsible for finding an efficient way to transport the elements needed by the hydrogen fuel cells used to power electric vehicles.
Although buses will emit CO2 and water through the exhaust pipe, they can be considered completely neutral as this CO2 is used by the system itself to make the fuel.
Project managers have stressed that at no point in the fuel-making process are ants or bees required to be killed for formic acid.
Although the first prototype for the production process was introduced in January 2016 and the first successful tests have already been carried out, the current system is much more powerful (up to 25 kW of power) and seems to be officially ready to start at the end of this year.
The European Commission (EC) recently presented the new objectives for the Clean Mobility Package Horizon 2030. It sets out the environmental objectives that affect the passenger transport sector and the legislative measures that should be applied to all new vehicles from the year 2025. Although all new vehicles Continue reading
After waking up in the morning, many of us turn to a warm cup of coffee to overcome our grogginess and take on the day. It’s a part of many people’s morning routines, but in a few years’ time, it may be that buses get their morning coffee as well. Bio-bean, a British startup, has teamed up with Shell Corporation and Argent Energy to work on a Continue reading
Between being caught up in daily routines and the excitement of holiday planning, it’s often easy to forget about the environmental impact our choices make. Travelling by coach rather than car is one decision that helps decrease the carbon emissions in the air by reducing traffic. Fortunately, cities like York Continue reading
The Scottish coach company megabus is known for low-cost tickets starting from only £1. Maybe this is one of the reasons why its luxury sleepercoach service could not quite convince UK travellers and will be discontinued on 21 May. The overnight coach service was launched in 2013 and has been connecting Continue reading
If you believe buses are just used for boring school trips or overcrowded public transport, take a closer look at the international bus industry. Tinkerer and innovators around the world are working on groundbreaking projects to improve the attractiveness of buses as means of transportation as well Continue reading
Taking the coach is one of the most affordable and eco-friendly ways of travelling but it can also be fairly time-consuming. If you’re an experienced traveller, then this won’t bother you too much but if you’re travelling with children, it’s a different scenario. This is why we came up with some pieces of advice Continue reading
The polar ice caps are melting which is why the CheckMyBus elves are getting a bit concerned. After all, their boss Santa travels around the whole world every year and that cannot really be such an eco-friendly endeavour. They couldn’t help but wonder: are flying reindeer a modern and low-emission Continue reading
For the last 75 years, Wonder Woman has inspired young girls and women from all over the world. The DC comic book heroine filled a void in the otherwise male-dominated comic sphere, which is why the United Nations have decided to celebrate the iconic role-model by honouring her with a day of her own. Continue reading
Every year, on 22 September about 1,500 cities in 40 countries celebrate World Car Free Day. In order to cut down pollution and to reduce traffic and noise, cars are either banned from large parts of the city centres or other activities and competitions are offered which are meant to encourage the population Continue reading
