Anders Bo Skov, a Master's degree student in chemistry by the University of Copenhagen, together with Ma?tre Mogens Brøndsted Nielsen and his team, have always been developing molecules capable of harvesting solar power and storing it for a great deal of00 time and releasing it on preference.
"My research into the dihydroazulene-vinylheptafulvene (DHA-VHF) system has been focused on stripping the software of a stabilizing group (a cyano-group), which turned out to increase to amassed energy, and at the same time increase the duration calorie consumption can be stored for from precious time to a hundred years, " Skov talks about.
One major hurdle was one apparent law of nature: As you move the capacity of the molecules to hold calorie consumption seemed to improve, the capacity to store it out time dropped; and vice versa. Speak to, every time the group managed to design modified molecules, the molecules lost a selection of their ability to hold their shape.
Skov's molecule is a so-called photochromic model, in which a molecule (DHA) changes this structure into a different molecule (VHF) upon irradiation. "The VHF is regarded as a less stable species, and so it could seek to release the energy as protect over time, reverting into DHA, " the researcher explains.
Finally, having been able to double the energy density from inside the molecule and it can predictably hold this shape for decades.
However , releasing collected solar energy on demand still stayed a challenge. "We have experience in the catalyzing the energy-release through are metal salts, " Skov talks about. "However the common ones used tend to be too harsh for my chemical, so I am working on finding more gentle catalysts, both within the metal additionally non-metal 'library' of chemical factors. "
The research breakthrough could be a game-changer in solar energy storage. "Currently, option solutions exist, to my knowledge, so that storage of solar energy for more than a couple of hours without significant losses of energy, " Skov says. "My discovery, in case put into use, could allow storage from solar energy for years without losses of speaking of. "
What is more, Skov's stage does not release carbon dioxide or crank out toxic byproducts. "The significance of the is primarily in the comparison as well as competing solutions, " he says. Si solar cells are very costly to produce regarding carbon dioxide production and current calorie consumption storage solutions (i. e., batteries) typically include metal and other contaminated materials to be effective. In these regards, good competitive advantage of Skov's material could it be is more environmentally friendly.
"To me, in the exciting part of the advance is that the boost of energy stored combined with an increase in livestock time is a chemical rarity, " Skov says. He defied the man's undergraduate books on the topic, on a tell of principles of nature why say the two should be inversely associated, and not increase together. "If they allow this once, we can do it again, making this model ideal for use. "
The revolutionary research could be extremely useful in real life. "A viable solution to storing solar power for times when the sun is tight and heating is expensive factors ultimate application for this research, to my way of thinking, " says Skov.
Currently, the man's system's energy storage capacity is at in existance 25%, and he is focusing on search engine marketing. "We are working with the same model, mainly trying to increase the energy ability to be stored, both by lasting in the same direction, but also by new structural changes to the system, " Skov continues. "The catalyst an issue also beckons, of course , and we intend to find a catalyst which is mild the two to our material, and to the environment. "
Skov and Brøndsted, who leaders the Center for Exploitation of Solar technology at the University of Copenhagen, obtain published the paper "Towards Solar technology Storage in the Photochromic Dihydroazulene-Vinylheptafulvene System" in Chemistry — A European Work schedule.
