Looking back over years of research into the topic of hybrid systems based on different combinations of solar, wind, hydro and other renewables, an international group of scientists found strong potential for strategies to exploit complementarity between the different sources integrate more intermittent renewables onto regional and national grids. The scientists present a series of conclusions and recommendations that aim to push research in hybrid renewables forward.

The 18-meter long solar cell-clad trailer is said to enable fuel savings of 5-10% in Sweden. Swedish thin-film manufacturer Midsummer is a partner on the project.

A study from Sweden seeks to consider how PV could be sympathetically installed on historic buildings. The researchers propose a target-based approach for assessing panel visibility.

The devices, developed by a European research team, are said to have twice the energy density of conventional aluminum devices. The scientists used a cathode made of anthraquinone, instead of one based on graphene, increasing energy density.
