A solution seems to have emerged to address the excess electricity problem from renewables in the UK.
Green energy, when produced in excess, can be converted into hydrogen that could be used in heating and other parts of the energy system, a report from the Institution of Mechanical Engineers (iMechE) has said.
One of the problems with the renewable energy is that it is produced in excess in times when demand may be low. Many power stations are inflexible and hard to turn off at times of high outputs.
According to the engineers at iMechE, the energy can be used to split water into hydrogen and oxygen, and the hydrogen can be used as an energy source.
Using lithium batteries to store the excess energy is one of the other alternatives being used.
