I tested the Tesla Powerwall 3 – going off-grid feels good, but it's a long-term investment rather than a quick fix

The construction of large and small battery storage systems is booming in Germany. The systems can help to reduce electricity prices. However, today's batteries come mainly from Chinese manufacturers. This could give rise to a new discussion on the safety of critical infrastructure.

I tested the Tesla Powerwall 3 – going off-grid feels good, but it's a long-term investment rather than a quick fix

Tesla's Powerall 3 is a giant battery pack for your house –I tried one in the UK's Lake District to see whether it's worth the painful initial investment.

Big battery boom could deliver 18 GW of grid-scale energy storage by 2035

BNEF says Australia is on the cusp of a big battery boom that could deliver an eight-fold increase in capacity.

Among the storage systems, the compressed air one is inherently interesting. Up to now, however, it was still too expensive to implement it. But some researchers may have found a solution. Everyone knows now. If we want to be able to make the difference to intermittent renewable energies, we will have to equip ourselves with electricity storage systems. Batteries, of course. But also other technologies. Like the one that the experts know under t…
