Hemp Biofuel Could Ease Our Dependence On Fossil Fuels By Ellijah Pickering - July 28, 2018 “Ministry of Hemp” After legalisation, hemp biofuel could be a key part of reducing our dependence on fossil fuels. Fuel is everything. America would not be the hyper-efficient economy it is today without something to power our cars, computers, and our Roomba vacuum cleaners. We would be nothing but Neolithic farmers without our electricity and gasoline. But, anything that is truly valuable always comes at a price. Traditional fuel sources hurt the environment, and they’re running out. Air pollution from processing fossil fuels harms the troposphere, and indirectly depletes ozone from our atmosphere. The price for hyper efficiency is evident, which is why alternative fuel sources are becoming so important. Today we focus on a fuel source that hits close to home. That alternative is hemp biofuel. The cannabis plant is the gift that keeps on giving’. This magic plant gives us CBD oil, THC, hemp fibres and even fuel! Researchers have made hemp into two types of biofuel: biodiesel and ethanol. HEMP BIODISEL Biodiesel is produced by the pressing of hemp seeds to extract their oils & fats. After the extraction, the product is then put through more steps to make it into a usable hemp biofuel for your car. If you’re curious to learn about the specifics of biodiesel production, the process is thoroughly explained by hemp.com. The argument for hemp-derived biodiesel comes down to convenience. If processed correctly, biodiesel can be put into any diesel-powered automobiles. It can be stored and transported like diesel, so there isn’t a need to create a new system for transportation. It even replaces the smell of traditional diesel with the smell of hemp. USING HEMP TO MAKE ETHANOL Ethanol is traditionally made from wheat- based crops such as corn and barley. It’s traditionally used as an additive to gasoline, which gave way to our “flex-fuel” vehicles of today. Hemp can be made into ethanol by various forms of fermentation. Using hemp as the main source of ethanol, instead of food crops like wheat & corn has clear advantages. Not using food crops as a fuel source allows more efficiency in food production, and hemp can be grown in lower quality conditions unlike corn or wheat. Hemp-derived ethanol also shares the advantages of transportation and usability as biodiesel. HEMP BIOFUEL OFFERS A MORE SUSTAINABLE ALTERNATIVE Fuel alternatives like this can seem like a no- brainer to replace our traditional fossil-fuel sources, but there are drawbacks to these alternative techniques.
