When we think of energy from sunlight, we usually think of solar power. But there may be another, even more exciting possibility that scientist have been working on: artificial photosynthesis (AP). If it can be made to work, it would result in hydrogen that could be used as is, or combined with other molecules into liquid form.
“If it works it would be magical,” Bill Gates told Reuters recently, “because with liquids you don’t have the intermittency problem batteries. You can put the liquid into a big tank and burn it whenever you want.”The upshot: It’s hoped that AP could go a long way towards meeting our energy needs for operating running our cars and even powering our urban areas.
Professor Leone Spiccia from the School of Chemistry at Monash tells World Economic Forum, “Electrochemical splitting of water could provide a cheap, clean and renewable source of hydrogen as the ultimately sustainable fuel.
We all studied photosynthesis in school: It’s the process by which plants convert water and carbon dioxide into carbohydrates. The idea of artificial photosynthesis is to use sunlight to…
