Many American universities hope to use algae to develop diesel fuel blends

According to foreign media reports, a team of experts from the University of Michigan and researchers from Penn State and the University of Delaware has launched a research collaboration. The project involves $ 2.5 million in funding. Looking for feasible solutions to deal with climate change and air pollution.

Creating economical algae fuel for vehicles is not a new idea, they chose algae as a breakthrough in research and development. The R & D team hopes to separate oil from algae and add it to a viable diesel fuel mixture, which can be used as a renewable energy source.

The team first selected the correct algae species from tens of thousands of algae species. The research group will try to finalize an algae species that needs to resist disease and grow rapidly in a large volume, and the chemical properties of the algae need to match the engine. Unfortunately, algae can easily pollute water quality, and pure algae biofuels do not seem feasible.

Compared with gasoline engines, diesel engines can greatly improve fuel economy and traction advantages.

The research team pointed out that diesel vehicles and equipment are mainly responsible for nearly half of the nitrogen oxides and two-thirds of particulate pollutants in the US transportation industry, and such particulates also cause premature death.

However, the researchers pointed out that if the diesel engine is properly designed and improved, it can ensure that the particulate matter after combustion of the fuel is kept as low as possible, which helps limit the greenhouse gas emissions.

Boehman said: "Diesel engines play a very important role in improving fuel economy and reducing carbon dioxide emissions in exhaust, which is one of the effective ways to reduce vehicle carbon emissions."

The funding from the US Department of Energy is dedicated to the development of diesel fuel, and the process envisioned by the researchers may also be used for other fuels.

Professor Cardinale said: "The team has designed various types of biofuels, whose chemical properties are in line with current needs, or can be matched with diesel engines, paving the way for future biofuel design." (Text / Li Wenlong)

Grow Lights

Grow lights are artificial light sources that mimic the sun's spectrum and intensity to provide necessary illumination for optimal plant growth. They are designed to produce the right amount of light at the right wavelengths to ensure healthy and vibrant plant growth. All of our full spectrum grow lights have those functions, with sunlike full spectrum, and dimmer to adjust light intensity. Grow lights can also be used to enhance colors, boost plant immunity, and increase crop yields. Ours are mainly led grow lights for cannabis.
