Biological engineering methods can help supply materials in the future

Scientific researchers have presented a new bio-energy and recycling process that can help produce enough fuel for all cars in the United States. This new method can even provide enough fuel for other vehicles by recycling all the wasted CO ₂ in the production of materials, and seems to be more efficient than previous techniques. here.

Transportation vehicles in the United States consume a large amount of oil 16% of the world and emit about 8% of global CO2. Oil prices and concerns about global warming have spurred studies to create clean biofuels to replace crude.

This is a method of mixing hydrogen and carbon gas that can help create diesel fuel from coal or biotechnology without adding any CO2 into the atmosphere. Biofuel production processes can use plant or animal materials such as beans or sugarcane. However, the conversion of this vegetation into fuel is effective with two-thirds of the loss is CO ₂ during the conversion process.

Chemical engineers led by Purdue University directed Professor Rakesh Agrawal have reported this new method on the US National Academy of Sciences's Minutes of Records, a very unique method because it Use hydrogen gas from energy sources to keep all the CO ₂ generated from fuel production.

Agrawal's new method differs from current biofuel production methods because it reacts to excess CO ₂ by hydrogen to produce more diesel. The hydrogen gas in the reaction can be obtained from water molecules by using energy from non-degradable energy sources such as solar energy or nuclear energy.

Experts say the effect is so beneficial that the same amount of biomass is estimated to meet only 30% of US shipping demand (1.239 billion tons), but can now meet. total. The amount of biofuels produced in an area covers about 10% of the US biology carpet

Although cars that use diesel fuel still emit carbon dioxide and that amount of carbon dioxide from the atmosphere can be absorbed by growing many biological mats that will essentially create a balanced CO2 cycle.

Professor Agrawal told Cosmos Online : This is a much cleaner process than the process from coal or biological carpet to material. It is also of great benefit that it is possible to use existing equipment to transport while it cannot be transported for energy such as hydrogen.

He predicts using this new method, only the industry of producing raw materials can meet demand when coal resources are exhausted and can even produce a new mixed hydrogen-carbon economy.

For trains, planes, other types of engines, research experts also point out that the biggest challenge for energy is produced from fuel sources such as nuclear, sun, wind and fuel. Other non-degradable materials are storage problems. For an available space on the ship, the energy supply density of the power supply unit and hydrogen gas will greatly limit the control distance. Similarly, energy and prices associated with transportation will more or less create price division.

Professor Behdad Moghtaderi of Newcastle University's Center for Energy Research in New South Wales explains this is an interesting concept that scientists have mentioned, although the method is considered successful in the US but there is still a weakness that is the production of hydrogen.

The hydrogen gas used in this new method will be created by using solar, wind and nuclear power to separate water molecules. This is difficult to accomplish in Australia simply because they do not have enough water to produce Hidro in a wide range.

Researchers believe that the production of Hidro is an issue to be considered. To realize this new chemical method, hydrogen production methods and gas supplies from plant biotechnology can be developed to regenerate CO2.

Currently the shipping area is emitting a large amount of CO2, and there is a lot of discussion about technical issues to help extract the CO2 from the atmosphere.

Cosmos online had a meeting with a collaborative industrial support research center on greenhouse gas emissions techniques in Canberra to discuss how new research impacts industry related. taking carbon out of the atmosphere. However, they refused to talk.

The study is in the archives of the National Academy of Sciences.
