Solar energy is using the sun as a source of power, which is retained through photovoltaic (PV) and concentrating solar power (CSP) technologies (energy.gov). PV technology is the use of solar panels that convert sunlight into electricity, and CPS is using mirrors to convert sunlight into heat. Solar energy is a very important form of energy because it is a resource that we do not need to harvest by exploiting the earth. The sun is a giant ball of energy just waiting for us to absorb the rays it shines down on the planet. Based on a report from the International Energy Agency, solar energy technology is rising in popularity, increasing by 50% in 2016, with mostly China and secondly the US leading the charge in the expansion (USA today). The growing mode of solar technology is the use of PV technology / solar panels, because of mass installation in China and support from the Chinese government. With the rising popularity of solar technology, it is only natural that the next step in pursuing sustainable forms of energy would be to develop artificial photosynthesis.
What is artificial photosynthesis? It is a way of storing the energy that it collected from solar technology. Right now, we can use solar panels to power our stuff, but it really is only useful during sunny seasons. If there was a way to store the energy collected for use during the winter/darker seasons, people could be using sustainable energy all year long. That is the goal of creating artificial photosynthesis. With the creation of artificial photosynthesis, scientists hope to “store solar energy in a way that can be used later on.” (ZME Science). In order to actually start the process of creating artificial photosynthesis, there needs to be a catalyst for the chemical reaction of converting sunlight into energy. Plants use photosynthesis to make sugar from the carbon dioxide in the air, and the process is jump-started by a catalyst. The catalysts science has available to it are usually one-atom catalysts, and there is an exploration into the production of a 2-atom catalyst. Boston College Associate Professor of Chemistry Dunwei Wang is heading up experimentation into a 2-atom catalyst and was able to produce one that is durable and great for water oxidation (ZME Science). The catalyst created is made of iridium, which is a factor into the 2-atom catalysts strength. Having a durable catalyst could be the first major step towards a future where the sun powers the planet, rather than the precious resources we have almost drained completely from the earth. Professor Wang explains that artificial photosynthesis stores energy by directly harvesting solar energy and storing the energy in chemical bonds, similar to how photosynthesis is performed but with higher efficiencies and lower cost.” (IFL Science). Further study is still needed before artificial photosynthesis can begin production and get into the hands of the people, but there are high hopes because technology like this would be so beneficial to humanity and would help the world move towards a future with less negative environmental impact, and reduce our carbon footprint, especially since the artificial photosynthesis is literally taking in carbon dioxide and turning into energy.
