While the price for lithium-ion batteries has dropped significantly in recent years, the technology is still a tad too expensive to be the best solution for the long-term storage of renewable energy, most of which is weather-dependent. As such, innovators are looking beyond … [Read more...] about These ultra-low-cost batteries use CO2 to store renewable energy

We could soon use hills as batteries to store solar and wind energy
While solar and wind power are now the cheapest sources of energy across the world, energy storage remains one of the biggest hurdles preventing a full switch to renewables. This is because it’s still quite expensive to use batteries for storing power. A startup, however, has … [Read more...] about We could soon use hills as batteries to store solar and wind energy
This new material could help store renewable energy for months at a time
As renewable energy generation continues to grow at an exponential rate, it is essential that we find technologies that can efficiently store that energy until it’s needed. A new material identified by scientists at Lancaster University could offer exactly that. Known as a … [Read more...] about This new material could help store renewable energy for months at a time
New power plant uses liquid air to store renewable energy
While batteries are great for short-term energy storage, they are still too expensive to do long-term energy storage. Plus, batteries require minerals that are becoming increasingly scarce as the world moves towards power systems based on variable renewable energy. Fortunately, … [Read more...] about New power plant uses liquid air to store renewable energy
This system uses massive weights to store energy
When you coil a spring, you load it with a bunch of potential energy that gets released when you let go. Using the same basic principle, a Scottish company called Gravitricity is creating an energy storage facility that uses weights instead of springs to store energy. The idea … [Read more...] about This system uses massive weights to store energy
