According to foreign media reports, a team of researchers at the University of Massachusetts Lowell Campus (UMass Lowell) has discovered a new and more efficient way to power electric vehicles. The innovative technology was developed by Professor David Ryan, the head of the Department of Chemistry, and a group of students at the University of Massachusetts Lowell campus. It enables electric vehicles of all sizes to travel longer distances while maintaining zero emissions. The new technology uses water, carbon dioxide and metallic cobalt to produce hydrogen on demand at relatively low temperatures and pressures.
Professor David Ryan said that most electric vehicles currently on the road rely on rechargeable batteries, but batteries have limitations in storage capacity, charging time, and cost. Therefore, the current technology is only applicable to small cars, but not to large vehicles such as trucks and buses. In contrast, the new technology developed by the team at the University of Massachusetts Lowell campus can power electric vehicles of all sizes.
The researchers' experimental device consisted of a stainless steel tank filled with cobalt. The carbonic acid solution made of carbon dioxide and water was pumped into the tank, and then heated to about 150 degrees. The carbonic acid solution was also compressed to 45 pounds per inch. In this case, cobalt metal is not the catalyst, and cobalt carbonate is the catalyst. The carbonic acid solution converts metallic cobalt to cobalt oxide, and hydrogen and carbon dioxide are produced during the conversion process. Then, hydrogen is directly injected into the fuel cell of the electric car. The hydrogen will mix with the oxygen in the air to generate electricity and water. The electricity can power the system and control the car motor, rechargeable battery, and headlights.
Despite the many advantages of hydrogen fuel technology, due to the high flammability of the gas, the technology has not been widely used due to safety concerns. Ryan said: "This process does not store any hydrogen, so it is very safe, does not cause transportation problems, and greatly reduces the possibility of fire or explosion. Moreover, the hydrogen produced by this technology has a purity of more than 95%. Combustion of hydrogen is very clean It does not produce carbon dioxide, only water. Hydrogen is used in fuel cells, where it is combined with oxygen in the air to generate electricity with an efficiency of up to 85%. "
Once the metal cobalt in the tank is used up, it is converted into cobalt oxide. The driver needs to replace a new tank every 300 to 400 miles. Then, using renewable energy such as wind or solar energy, the cobalt metal in the old tank is regenerated.
According to industry observers, due to increasing demand for green energy, the market value of the hydrogen market is expected to increase to approximately US $ 199.0 billion (approximately RMB1.3369 billion) in the next four years.
Ryan said: "Unlike fossil fuels, hydrogen must be produced manually if it is to be extracted from the ground or extracted. The current method of producing hydrogen is expensive and inefficient, and the lack of necessary infrastructure hinders the extraction of oil. The transition from an economy to a hydrogen economy. We hope that the catalytic hydrogen technology we have developed can help solve all such challenges. "
Researchers have obtained provisional patents for the technology and are still waiting for a complete patent for the technology. In addition to receiving support from the University of Massachusetts Lowell Campus, the research team also received a US $ 25,000 (about 167,955 yuan) seed fund from the Massachusetts Clean Energy Center to help promote the innovative technology from the laboratory to the market .
