Researchers in Sweden have demonstrated efficient solar energy storage in a chemical liquid. The stored energy can be transported and then released as heat whenever needed while the storage medium is fully recovered – a so-called molecular solar thermal system.

The state of California has submitted a bill that would mandate the installation of solar power on all new buildings. Current law only mandates new buildings to be “solar ready” meaning, that there has to be at least 15 % of the roof’s area free of shades. However, at the moment the bill is in the early stage and a lot is still to be figured out.

A call to end uncertainty on solar heat in the UK

A group of 21 organisations called on the British government to end the uncertainty and retain solar thermal in the Renewable Heath Incentive (RHI). In a letter sent to the minister for energy and intellectual property, Baroness Neville-Rolfe, representatives of the solar industry, local governments, manufacturers, housing providers, land owners and environmental groups said that the technology should not be excluded from the support scheme.
