When: Annually, August 10.
On August 10 every year, it is International Biodiesel Day. This is a day focusing on an alternative to the more polluting version of diesel.
Origin
The invention of biodiesel takes centre stage on 10 August, the International Biodiesel Day. This is special because this is the birth anniversary of the ordinary diesel engine in 1893. Responsible for this design was Rudolf Christian Karl Diesel (18 March 1858 – 29 September 1913). Biodiesel no longer has much to do with that original fuel, as it is an alternative. A natural(er) alternative. This is an alternative to the limited supply of petroleum that must be called upon.
What is biodiesel?
Biodiesel is produced from vegetable oils or animal fats. It is a renewable energy source and can help reduce greenhouse gas emissions and fuel dependency.
Production process
The biodiesel production process starts with the collection of vegetable oils, such as soybean oil, or animal fats. These oils and fats consist mainly of triglycerides, which are converted into biodiesel by a chemical process called transesterification. This involves mixing the triglycerides with an alcohol, usually methanol, and a catalyst such as sodium hydroxide or potassium hydroxide. This process breaks down the triglycerides into glycerol and methyl esters, the chemical name for biodiesel.
Species and mixtures
Biodiesel can be used pure (B100) or blended with conventional diesel in various ratios. Common blends are B5 (5% biodiesel and 95% conventional diesel) and B20 (20% biodiesel and 80% conventional diesel). These blends can be used in existing diesel engines without major modifications.
Advantages
One of the main advantages of biodiesel is that it is a renewable energy source. Unlike fossil fuels, which take millions of years to form, biodiesel can be produced from crops that are harvested annually. Moreover, using biodiesel can reduce emissions of harmful substances such as carbon dioxide (CO2), hydrocarbons and particulates. This makes biodiesel a more environmentally friendly alternative to conventional diesel.
Challenges
While biodiesel offers many advantages, there are also some challenges. One of the biggest challenges is feedstock availability. Using food crops such as soya to produce biodiesel can lead to competition with food supplies and higher food prices. Therefore, there is increasing research into producing biodiesel from non-food crops and waste products, such as used frying oil and animal waste.
Future prospects
The future of biodiesel looks promising, especially with the development of second-generation biofuels. These fuels are produced from waste products and non-food crops, making them a more sustainable alternative. Moreover, technological innovations continue to make the production process more efficient and cost-effective.
In conclusion, biodiesel is a promising renewable energy source that can contribute to a more sustainable future. Although challenges remain, ongoing developments in technology and feedstocks offer hope for wider acceptance and use of biodiesel in the coming years.
About this day
Sustainability is at the heart of the day. Then, in particular, it is about emphasising that biodiesel is or should be a suitable alternative to ordinary diesel. Where it is not yet possible, it should be. What challenges this might pose is something to think about on a day like this. By the way, this need not be limited to just the International Biodiesel Day. Sustainable (bio)fuel is something that should not be limited to one day.
Biodiesel as an alternative
Today, biodiesel is recognised worldwide as an important renewable energy source. Many countries have introduced policies and subsidies to encourage biodiesel production and use. Much research is also being done to develop second-generation biofuels, which are produced from waste products and non-food crops.
Future
The question is what the future looks like. What will happen? That depends primarily on technological developments. In addition, political decisions play an important role. That is why the choice of the Dutch political parties forming the Dutch right-wing government (PVV, VVD, NSC and BBB) was not particularly motivating. One chose to bring back red diesel for the agricultural sector, as here can be read. This is duty-free diesel. Good news for the agricultural sector perhaps, bad news for sustainability and the environment. With that, this cabinet showed where its priorities lay. Red diesel was abolished in 2013. This, incidentally, puts the Netherlands in an exceptional position.
The future of biodiesel itself, by the way, does look more interesting. Perhaps even more promising. Despite the decision taken in the Netherlands. Technological developments continue and awareness is only growing. More and more people are aware that there is a need to move away from ordinary diesel and then alternative energy sources come into the picture. For example, biodiesel. When it comes to global energy supply, biodiesel may play an increasingly significant role. The International Biodiesel Day is especially important for this very reason. It is also a good time to look ahead, to determine what still needs to be done.
