In the second episode of the series, Horizons presenter Adam Shaw visits the Royal Institution in London to meet Nobel Prize-winning chemist Professor Sir Harry Kroto to discuss the importance of developing new sources of renewable energy.

Best known for his role in the groundbreaking discovery of C60, a new form of carbon molecule, heralded as one of the cornerstones of the burgeoning field of nanoscience, Sir Harry Kroto argues that new sources of renewable energy will play a vital role in meeting the increasing demand for power from an ever expanding and rapidly urbanising global population.

Sir Harry Kroto discusses his belief that organic chemistry could provide a solution to the need for more sustainable sources of energy, including the role C60 could play in the development of the next generation of solar power.

“We use a million years’ worth of fossil fuel in one year,” says Professor Sir Harry Kroto. “We have to up our efficiency by a factor of a million, that’s the problem. But I think in the future, chemistry - or what I call 21st century chemistry, nanoscience and nanotechnology - has the possibility of solving many of these problems of sustainability.”

In Cambridge, Adam meets the team at Eight19 / Azuri who believe that the latest developments in printable plastic organic photovoltaic cells, which use carbon instead of silicon, could bring cheap renewable solar power to millions of off-grid consumers in developing countries.

Finally Adam travels to Boston to meet Harvard professor Daniel Nocera, creator of the ‘artificial leaf’, a device that aims to mimic the natural process of photosynthesis in plants to turn solar energy into storable hydrogen gas, which could revolutionise the way we look at power.
