Why is algae more valuable for biofuel?
Advantages for Biofuels A significant advantage of using algae for biofuels is that it need not displace farmland used for growing food sources. The Department of Energy reports that algae have the potential to yield at least 30 times more energy than land-based crops currently used to produce biofuels.
Why are algae considered a very good biofuel resource quizlet?
algae are potentially the next good source of energy because: The tiny organisms are very good at trapping and storing energy, the oil they produce is rich in chemical energy, all they need is sunlight, carbon dioxide, adn water, they can also grow rapidly.
Why are energy rich lipids from algae more useful as a fuel than energy rich sugars and other carbohydrates produced by photosynthetic organisms such as corn and wheat?
Why are energy-rich lipids from algae more useful as a fuel than energy-rich sugars and other carbohydrates produced by photosynthetic organisms such as corn and wheat? The sugars contain less chemical energy than the lipids and the lipids can be used directly as fuel.

Why is algae good for renewable fuel?
Algae are believed to be a good source of renewable energy because of its rapid growth rate and its ability to be cultivated in waste water or waste land. Several companies and government agencies are making efforts to reduce capital cost and operating costs and make algae fuel production commercially viable.
What are the advantages of algae?
Here are 10 reasons why algae are a promising new source of fuel and other products:
- Algae Grow Fast. …
- Algae Can Have High Biofuel Yields. …
- Algae Consume CO2. …
- Algae Do Not Compete With Agriculture. …
- Microalgal Biomass Can Be Used for Fuel, Feed and Food. …
- Macroalgae Can Be Grown in the Sea.
Does algae require less fertilizer than corn?
How do the environmental costs of growing algae for biofuel production compare to other crop options? Algae require less fertilizer than corn.
Why is biofuel produced by algae considered to be carbon neutral?
Because algae use carbon dioxide through photosynthesis, algae biofuel is carbon neutral. The CO2 produced by burning the fuel is the same amount of CO2 that the algae took to grow and produce the fuel. This means that the net CO2 emission is zero, the same as if the algae had never been grown.
What are the benefits of using native plants instead of corn to create biofuels quizlet?
Advantages include the ability to control conditions (e.g., carbon dioxide concentration, temperature, nutrients, pH) to maximize lipid production from sunlight and carbon dioxide. The major disadvantage is the cost of maintaining such a sophisticated system.
How do environmental costs of growing algae for biofuel production compare to other crop options?
How do the environmental costs of growing algae for biofuel production compare to other crop options? Algae require less fertilizer than corn. When considering which biofuel is the most sustainable, which of these must be considered? The fuel used to run our cars contains _____ energy.
Is algae biofuel sustainable?
Algae are considered as clean renewable energy source as they do not cause pollution to the ecosystem. Biofuels, currently produced through algal biomass are bioethanol, biomethanol, biobutanol, biodiesel, biomethane, biohydrogen, and bio-oil.

What is an advantage that algae biofuel has over plant based biofuels quizlet?
Why are algae considered more valuable for biofuel than plants (such as corn)? Many types of algae can divert the sugars they make by photosynthesis into lipids that can be used to make biodiesel. Biodiesel is a promising replacement for fossil fuels.
How does algae work as a biofuel?
Algal oils, just like oils produced by soy, canola, palm and the less-known jatropha plants, can be made good biodiesel feedstocks through transesterification. In that process, a catalyst creates a biodiesel fuel (consisting of fatty acid methyl esters) by hydrolyzing and methylating fatty acids in the oils.
What advantage does algae have over plants?
Algae take CO2 from the Earth's atmosphere through photosynthesis in the same way that plants and trees do. But they can absorb more CO2 and they grow much faster: 1m3 of algae culture is equivalent to 100m2 of forest in carbon capture. They are not dependent on agricultural land, fertilisation or freshwater.
Why is algae better than corn?
With already limited space, algae is a better alternative because it can grow on land not suited for agriculture. Also, because of microalgae's high lipid/biomass yield, it needs less land to produce the same amount of biofuel compared to corn and soybean.
How do algae grow biofuels?
Algae for biofuels is typically farmed in ponds, using the sun. Hann's method will be to “potentially grow the algae in a confined space, just using electricity from the solar panels,” the university says. A bioreactor, which is a way to grow algae, typically using light.
What are two reasons why algae is good for making renewable fuel?
Algae are believed to be a good source of renewable energy because of its rapid growth rate and its ability to be cultivated in waste water or waste land. Several companies and government agencies are making efforts to reduce capital cost and operating costs and make algae fuel production commercially viable.
How do the environmental costs of growing algae for biofuel production compare to other crop options?
How do the environmental costs of growing algae for biofuel production compare to other crop options? Algae require less fertilizer than corn. When considering which biofuel is the most sustainable, which of these must be considered? The fuel used to run our cars contains _____ energy.
What is necessary for biofuel production by photosynthetic algae?
they trap the energy of sunlight and store it in the form of molecules inside their cells. What things to algae need to produce this oil that is high in chemical energy? sunlight, carbon dioxide, water plus a few nutrients.
How is algae made into biofuel?
Microorganisms, such as algae, can be turned into biofuel through the extraction of fatty acid contained in biomolecules known as lipids. Extracting this fatty acid traditionally required removing all the water from the microorganism, resulting in a dry powder or biomass slurry.
What is a potential solution that is better than corn for biofuels?
Switchgrass a better biofuel source than corn.
Why is algae so important?
They play a vital role in aquatic ecosystems by forming the energy base of the food web for all aquatic organisms. As autotrophic organisms, algae convert water and carbon dioxide to sugar through the process of photosynthesis.
Is algae more sustainable than corn?
Growing algae for use in biofuels has a greater environmental impact than sources such as corn, switch grass and canola, researchers found in the first life-cycle assessment of algae growth.
How are algae helpful?
Algae is beneficial in the simplest manner because algae release oxygen as part of their metabolism, they serve to oxygenate the water. Green algae are preferred because blue-green algae float on the surface and are associated with water quality problems.
How is algae used to make biodiesel?
Algal oil is converted into biodiesel through a transesterification process. Oil extracted from the algae is mixed with alcohol and an acid or a base to produce the fatty acid methylesters that makes up the biodiesel. An excess of methanol is used to force the reaction to favor the right side of the equation.
