Returning to Vietnam at the end of November to attend the Global Young Vietnamese Intellectual Forum, Dr. Nguyen Duy Tam shared with all his dedication to renewable energy and green energy in Vietnam. After six years of research, Tam has successfully optimized the storage of renewable energy batteries. He invented a battery with high efficiency up to 80% and an average life span of about 35 years.

He said that the battery uses Vanadium material - a type used in rechargeable batteries. This material helps the battery store more energy than usual, even maximizing its storage capacity to infinite. It also allows the storage of renewable energy sources, especially solar and wind power, which means that the battery can store energy in electrolytes instead of electrode materials as traditional batteries, so there is no risk of fire, environmentally friendly.

One of the difficulties when making research on this type of battery is the cost, Tam said.

“Due to its specific characteristics and high cost, it’s very picky for scientists to do research on Vanadium battery. I myself have been supported by two companies in this fields from Austria and Germany to complete the project”.

Dr. Tam advises on transferring renewable energy technologies from abroad to Vietnam, instead of buying at high price.

He and his team at Nanyang Technological University, Singapore are now working on smart windows fabrication using electrochromic materials and nanostructured grapheme-based materials. This material has transparent characteristics. When a small voltage is passed, it will absorb the radiation from the infrared onwards, while still allowing light transmittance in the visible area.

Dr. Nguyen Duy Tam was born in Bo Trach (Quang Binh). After graduating from Hanoi National University, he applied for a research fellowship on reducing the amount of electricity needed to regulate room temperature.at Nanyang Technological University, Singapore. Since 2013, he has pursued research on renewable energy materials and technologies. To date, he has more than 20 international publications, a patented invention and many papers presented at international scientific conferences. In September, he was awarded the Best Presentation at the International Conference on Materials Science and Engineering in Australia.
