Biofuel made from seaweed is one of many options for future energy. New research from the University of Virginia shows that seaweed made biofuels the most energy efficient compared to other biofuels. That is, under the same planting area, the biofuel made from seaweed can be used to run cars for a longer period of time. In addition, the latest research shows that biofuels made from seaweeds have a burden on the environment because they emit carbon dioxide.
The research report of the University of Virginia shows that for farmers who want to maximize their profits, the fuel produced per hectare of seaweed is more efficient than economic crops such as rapeseed, and seaweed requires less of the planting environment. Strong. However, from the environmental point of view, in the process of making biofuel from seaweed, it takes a lot of water and emits carbon dioxide.
It is reported that a report entitled "Environmental Impact of Diesel Fuel Made from Seaweed" has been published online. Cress, a researcher at the school, said that they are currently considering a wide range of biofuels. Cress hopes that these reports will cause public controversy and allow people to have the right choice when using alternative fuels.
Creus said: “This is a question of value orientation. Do you think that driving SUVs over long distances will consume a lot of fuel? If so, we need to work hard to develop seaweed to ensure that it can actually produce more fuel. If we are concerned that energy consumption will cause climate change and lead to tight water supply, then we should think about how to better use rapeseed and other crops to produce biofuels."
The report from the University of Virginia may trigger industry rethinking of biofuels from seaweed. Traditionally, biofuels have obvious advantages because they do not compete with crops for arable land. Many experts once believed that seaweed biofuels are expected to become the ideal biofuel in the future.
Michel Stanley of the Scottish Marine Science Association stated: “The market competitiveness of seaweed biofuels cannot be achieved overnight. Therefore, the initial incentive measures are very important. Leyett believes that in order for seaweed to be economical, oil prices need to At $300 a barrel, high-value chemicals extracted from seaweed may change this situation."
At present, many companies around the world are actively preparing for the development of the biofuel market. Algae BioFuels, a subsidiary of PetroSun Company, announced in April 2007 that it will transfer biodiesel technology to Australia and convert seaweed oil into biodiesel. The production facility includes a biofuel refinery designed to produce 20 million gallons of biodiesel annually. According to the study, the amount of oil produced by seaweed exceeds 55,000 kilograms per hectare per year, which exceeds that of other oil crops. Israel Simm Biotech has developed a new technology to use the carbon dioxide emitted by power plants to cultivate seaweeds and then to obtain biofuels from them. Siemer Biosciences launched the study at an experimental farm in the Ashcroft power plant in 2004. The researchers separated carbon dioxide from the exhaust gas emitted by the power plant and cooled it to release it into the pond where the seaweed was cultivated. After cultivation, seaweed grows rapidly and yields are greatly increased. This provides raw material for the production of biofuels from seaweed.
