Cost-efficiency of plug-in hybrids calculated a thousand times faster

Plug-in hybrids have low fuel consumption, but require more costly parts than cars with a regular combustion engine. During development, the optimal cost balance must be calculated, which has been extremely time consuming to date. Now researchers have developed a new method that dramatically reduces the time needed for these calculations.

Reliable systems for recharging electric vehicles

The success of electric vehicle networks depends on economical vehicles - and efficient power grids. Existing power lines were not designed for the loads generated by electric vehicles. Fraunhofer researchers have developed prototype software to show grid operators how many electric vehicles can be connected to their local grid.

Algae from wastewater solves two problems

In one of the first studies to examine the potential for using municipal wastewater as a feedstock for algae-based biofuels, scientists found they could grow high-value strains of oil-rich algae while simultaneously removing more than 90 percent of nitrates and more than 50 percent of phosphorous from wastewater.

Saving energy with smart facades

Glass-fronted office buildings are some of the biggest energy consumers, and regulating their temperature is a big job. Now a facade element developed by Fraunhofer researchers and designers for glass fronts is to reduce energy consumption by harnessing solar thermal energy.

Adding renewable energy to power grid requires flexibility

A new study offers a comprehensive reimagining of the power grid that involves the coordinated integration of small-scale distributed energy resources. The study asserts that the proliferation of renewable energy must happen at the periphery of the power grid, which will enable the local generation of power that can be coordinated with flexible demand.
