What You'll Learn
GMO corn is a big part of today's fuel supply
GMO corn is a significant part of today's fuel supply, with corn being used to produce fuel (ethanol) and many other everyday items. In 2020, 92% of corn planted in the United States was GMO corn, and corn is the most commonly grown crop in the country. GMO corn is designed to be herbicide-resistant, insect-resistant, or both, which helps farmers use fewer pesticides.
The advantages of using GMO corn for biofuel production are similar to those of using GMO food crops. The faster and more accurate selection of desired traits saves time and money in developing cultivars. GMO corn also has benefits beyond fuel and food production. It can be used to produce everyday items such as toothpaste, dish detergent, paper, and cosmetics.
However, the use of GMO corn for fuel is controversial. Critics argue that it puts pressure on global food supplies and contributes to environmental degradation. They claim that diverting corn into energy production will lead to food price rises, especially for the poorest. Additionally, there are concerns about cross-contamination with existing corn crops, as the traits that make GMO corn attractive for ethanol production would negatively impact the food industry.
While GMO corn has the potential to revolutionize the fuel industry, it is essential to carefully consider the potential impacts on food security and the environment. The development and use of GMO corn for fuel must be balanced with the need to ensure a stable food supply and protect the environment.
In addition to GMO corn, other GMO crops, such as soybean, can also be used for biofuel production. Vegetable oils, including GMO oils, can be used as fuel sources for diesel engines, but modifications to the vehicle are usually required to address viscosity issues. Overall, GMO corn plays a significant role in today's fuel supply, and its use in this sector is likely to continue evolving.

GMO crops can be used to generate renewable fuels
The use of GE crops for biofuel production offers several advantages. Firstly, it improves biomass conversion properties by modifying the cell wall architecture, particularly lignin content and composition. This reduction in lignin concentration and changes in lignin composition have been correlated with higher glucose yields, improving ethanol production by up to 50%. Additionally, the faster and more accurate selection of desired traits in GE crops saves money and time in developing cultivars, benefiting farmers and customers. For instance, Syngenta's Enogen® corn is engineered to contain its own amylase enzyme, eliminating the need for its addition during production and reducing water, electricity, and natural gas consumption.
The use of biofuels like ethanol has had a significant impact on reducing carbon emissions. From 2005 to 2015, biofuels reduced US transportation-related carbon emissions by 589 million metric tons, equivalent to removing 124 million cars from the road over that decade. Corn ethanol reduces transportation-related greenhouse gas emissions by 43% compared to gasoline. Additionally, ethanol is blended into 97% of the US fuel supply, helping to protect against spikes in oil prices.
While GMO crops offer benefits for fuel production, there are also considerations to keep in mind. One disadvantage is the ethical perspective, where the use of crops for biofuels could be prioritized over food production if it is deemed viable and profitable. Additionally, the use of vegetable oils as biofuels has been explored, but it often requires modifications to vehicles to address viscosity issues. Straight vegetable oil (SVO) or pure plant oil (PPO) can be used in suitably modified engines, and preheating the oil can help reduce viscosity and surface tension. However, it is essential to follow the manufacturer's recommendations for fuel types to avoid damaging the vehicle or invalidating the warranty.

GMO crops can reduce carbon emissions
Genetically modified organisms (GMOs) have been a topic of debate for decades, with controversies surrounding their use in the human diet. However, GMOs have also been used in the energy sector, specifically in the production of renewable fuels. While the use of GMO crops for biofuels has advantages and disadvantages, one of their significant benefits is their potential to reduce carbon emissions.
GMO crops have been instrumental in reducing global greenhouse gas (GHG) emissions. The adoption of GMO insect-resistant and herbicide-tolerant technologies has significantly reduced the need for pesticide spraying, decreasing the environmental impact associated with herbicide and insecticide use. This reduction in chemical usage has led to a substantial decrease in fuel consumption, as fewer spray runs are required. In 2016, this resulted in a saving of 2,945 million kg of carbon dioxide, equivalent to taking 1.8 million cars off the road for a year. By 2020, the savings had increased to 23,631 million kg of carbon dioxide, equal to removing 15.6 million cars from the roads annually.
The use of GMO crops has facilitated a transition to "no-till" and "reduced-till" farming systems, also known as conservation tillage. This approach has significantly reduced tractor fuel usage, as tillage, or soil cultivation, is a fuel-intensive process. Conservation tillage has also enhanced soil quality and reduced soil erosion, leading to increased carbon sequestration in the soil, which further lowers GHG emissions.
Additionally, GMO crops can contribute to carbon dioxide assimilation through the intensification of crop production. The adoption of GMO technologies has resulted in higher crop yields and additional cropping, such as the facilitation of second cropping of soybeans after wheat in South America. While estimating the GHG emissions savings from additional production is complex due to varying variables, the increased assimilation of carbon dioxide contributes to reduced atmospheric carbon levels.
Overall, the use of GMO crops has positively impacted carbon emissions, contributing to a cleaner environment and helping to mitigate the detrimental effects of greenhouse gases on the planet. While further research is needed, the current evidence highlights the potential of GMO crops in reducing carbon emissions and promoting a more sustainable future.

Vegetable oil can be used as a diesel substitute
Vegetable oil can be used as a substitute for diesel fuel. Rudolf Diesel, the father of the engine that bears his name, initially designed it to run on coal dust but later modified it to run on vegetable oil. Straight vegetable oil (SVO) or pure plant oil (PPO) can be used as a fuel source in diesel engines, but only if the vehicle has been modified to address the viscosity issue. For example, adding a heat exchanger to preheat the oil can reduce its viscosity and surface tension. This is necessary because vegetable oil is very thick and sticky, which means it won't flow properly through the engine and won't burn efficiently. Mixing vegetable oil with conventional fuels like petroleum diesel is another solution to this problem.
Vegetable oil can also be processed into biodiesel, which can then be used as a fuel source. This process, called transesterification, involves some toxic and hazardous chemical transformations and is dangerous if not done correctly. A two-tank system can be used, with one tank for petroleum diesel to start and shut down the engine, and another for the heated vegetable oil. This ensures that no vegetable oil remains in the engine or fuel lines when the engine is started from cold.
The use of vegetable oil as a diesel substitute is not a new concept. Periodic petroleum shortages spurred research into vegetable oil as a diesel substitute during the 1930s, 1940s, 1970s, and early 1980s. The first commercial enterprise to allow consumers to run straight vegetable oil in their automobiles was Elsbett of West Germany in the 1970s. During the 1990s Bougainville conflict, islanders cut off from oil supplies due to a blockade fueled their vehicles with coconut oil. Today, biofuels like vegetable oil make up about 5% of UK diesel, and the government is investigating the environmental benefits of increasing this percentage.
While vegetable oil can be used as a diesel substitute, there are some drawbacks. Firstly, engine modifications are required, which can be costly and may not be worth it financially. Additionally, the cost of vegetable oil is approximately the same as diesel fuel, so there are minimal cost savings. Finally, the use of vegetable oil as a fuel source is controversial. While it can economically benefit farmers, customers, and the environment, there are ethical concerns about prioritizing crops for biofuels over food.

Vegetable oil can be turned into biodiesel
To turn vegetable oil into biodiesel, you will need the following:
- 1 litre of vegetable oil (e.g. canola oil, corn oil, or soybean oil)
- 3.5 grams of sodium hydroxide (also known as lye)
- 200 millilitres of methanol (methyl alcohol)
First, pour the methanol into a glass blender pitcher. Turn the blender on its lowest setting and slowly add the sodium hydroxide. Continue mixing until the sodium hydroxide has completely dissolved, which should take about 2 minutes. Then, add the vegetable oil to this mixture and continue blending on low speed for 20 to 30 minutes. Finally, pour the mixture into a wide-mouthed jar, where you will see the liquid start to separate into layers.
It is important to note that the chemicals used in this process are toxic, so it is strongly advised that this process is left to experts. If the chemical compounds are mixed or processed incorrectly, they can cause a very dangerous and hazardous chemical reaction.
Vegetable oil can also be used as a fuel source for diesel engines without being turned into biodiesel, but this requires modifications to the car to address the viscosity issue. For example, a heat exchanger can be added to preheat the oil, reducing its viscosity and surface tension.
