Scaling The Power of Renewable Energy

Advances in Nanoscience and Technology

Opportunity

Professor Uri Banin, founding director of the Hebrew University Center for Nanoscience and Nanotechnology, is on the precipice of a new day for solar power as he and his team work harnessing even more potential from the clean and renewable energy source.

The Situation Today

More energy from sunlight strikes the Earth in one hour than all the energy consumed on the planet in a year. However, there is a lot of daylight between our present use of solar energy and its enormous undeveloped potential. Professor Banin is investigating efficient methods of generating “solar fuel” from water and sunlight. Specifically, this aims at producing hydrogen from water via solar irradiation using nanotechnology.

Implications for Tomorrow

The most glaring opportunity for Professor Banin’s work is in transportation. His team has shown an ability to provide clean fuel where hydrogen is produced from water by clean and free sunlight before returning once more to water after being used to generate electricity in a fuel cell. The production of hydrogen can most efficiently be achieved using nanoparticles, acting as photo-catalysts, that utilize solar light and allow the transformation of light energy into chemical energy stored in the hydrogen fuel. Banin’s team has already demonstrated the feasibility of doing this using hybrid nanoparticles based on the gold-tipped nanostructures that he invented in 2004 while pioneering this area of nano research worldwide. Since then a multitude of concepts, new materials and promising applications of these photocatalysts have emerged. Ultimately, these advancements could cut transportation costs while reducing pollution throughout the world.

NEQST Steps

Hebrew University’s Nanoscience Center is due to move to new quarters in the NEQST (NanoscalE Quantum Science & Technology) Innovation Building, along with members of the Quantum Information Science Center. Their world class faculty members and high level research have positioned both Centers as leading their fields in Israel and on a global level.  Support for NEQST innovation in both centers and an investment in the shared premises and infrastructure will ensure continued breakthroughs not only in energy research but in nano-medicine, smart materials, quantum communications and more.
