Our planet Earth has an abundance of fuels such as coal, petroleum, which sadly is diminishing at an alarming rate . With increasing technology and population natural resources are not enough , hence scientists are looking for various other alternative forms of non -perishable fuel .





One of the most famous alternative sources of energy is solar power. Solar power is non-perishable and available in abundance. But the problem faced is that there is no proper way to store the energy for a long time. Hence therefore it is difficult to use in the long run.





Scientists in Sweden has developed a special kind of fuel which is capable of storing solar power for up to 18 years. It is referred as Solar Thermal Fuel . The scientists from University has been working on this molecular liquid fuel for almost a year .





The fuel is basically a molecule in liquid version which traps solar energy which can be used later on for various purposes. It is composed of hydrogen and nitrogen when heated it stores the solar energy within the molecules.





When the fuel cools down to room temperature the solar power still remains stored within the atoms turning into a new energized version called an isomer. Whenever the energy will be needed it will be drawn through a catalyst which converts it into its original form and releases the energy .





"The energy in this isomer can now be stored for up to 18 years," says one of the team, nanomaterials scientist Kasper Moth-Poulsen from Chalmers University.





"And when we come to extract the energy and use it, we get a warmth increase which is greater than we dared hope for."
