It has long been here, but work into vintage storage of solar energy from the 80s (and beyond) finally produces results. Recent developments provide existence proof for hybrid systems collecting and storing sunlight as heat for 24-hour use by scientists from Houston University in Texas. Nope, it’s not a solar system that concentrates and does not rely on molten salt or advanced oils. This contains Norbornadiene-quadricyclan, which is quite recent on the radar of CleanTechnica.
Norbornadiene-quadricyclane has been studied for solar power storage for at least 1983. It was then published by the American Chemical Society in the journal Industrial & Engineering Chemistry Process Design and production in the journal “Norbornadiene-quadricyclane method for the photochemical conversion and storage of solar energy.”
The center of a Norbornadiene-quadricyclane energy system lies in the use of solar energy in the form of heat to “flip” an isomer to another.
Sunlight produces an impact and transforms it into a norbornadiene-quadricyclane. The transition from one to the next often switches from low energy to high energy, where the energy storage angle is located.
In a norbornadiene-quadricyclane storage system, the capacity for high energy density is apparent and this explains the interest of researchers in renewable energies.
Which takes us to Houston University in Texas eventually. A team of scientists at the school cooked a new solar energy storage system for Norbornadiene-quadricyclans last autumn to address a series of issues that had hindered commercial development.
The new system avoids the losses caused by the transfer of energy from a collection unit into a stock platform by combining solar energy harvesting with an energy store in one hybrid system. As scientists describe in the journal Joule: It could involve applying the hybrid setup to different compounds, to optimize performance and increase scaling, to convert solar power to the immediate use and store the excess. CleanTechnica asks the researchers for an update, so keep up with it.
