A new zinc-based battery claims to do away with many of the disadvantages of lithium-ion batteries, and at a lower cost.
A study examining the historic prices of fossil fuels and renewable technologies suggests coal, oil and gas might not actually be as cheap as common.
Digital technologies are providing even small mini-grid developers with the tools to act like the big guys.
In Germany, industry is responsible for around a quarter of all CO2 emissions. We talked to Grischa Beier (IASS Potsdam) about how industry can reduce its massive CO2 emissions with the help of digitalisation.
Traditional lithium-ion batteries come with a whole host of issues, not least their expense. A Boston startup is looking to new materials for the next generation of batteries.
Solar power, heat pumps and waste heat - renewable energies are readily available. The former Pfaff factory site is being used to test what the climate-neutral neighbourhood of the future will look like.
There are many potential ways to store surplus renewable energy, but hydrogen is emerging as one of the most promising. New advances are making it cleaner and more practical.
Is it possible for heavily industrialized nations to create energy security with renewable power alone? Yes, it is! However, one of the most important factors in achieving this is efficient storage technologies.
Solar power is one of the best-known sources of renewable energy, but it is still only responsible for 3 percent of global electricity. What's keeping it back and how can it further develop?
