A team of researchers found 35,000 pairs of existing reservoirs, lakes and old mines in the US that could be turned into long-term energy storage – and they don’t need dams on rivers.
Renewable energy is expanding at a record pace, but still not fast enough. Here are the key areas to watch for progress in bringing more wind and solar into the power grid in 2022.
The UK government sees a reliable and low-carbon solution to future energy crises in nuclear power.
Electric cars are still more resilient to price shocks than vehicles running on fossil fuels.
The US is generating more electricity than ever from wind and solar power – but often it’s not needed at the time it’s produced. Advanced energy storage technologies make that power available 24/7.
Fifteen years ago electric power generation was the largest source of US greenhouse gas emissions. Now the power sector is leading the shift to a clean energy economy.
Britain's electricity sector continues to decarbonise, but its capacity to store energy lags far behind.
The electricity sector is expected to play a key role in Canada’s push to net-zero emissions. Enhancing long-distance transmission can be lower the cost of providing clean and reliable electricity.
A planned battery project in Essex will be ten times larger than the UK’s current biggest battery.
While much of the world moves towards zero-carbon economies, a NSW mega-plan for new renewables may set up the state as an energy superpower.
Hydrogen is feted as the key to a dynamic green economy. But is it the best choice for decarbonisation in all cases?
Don't count nuclear energy out – it may be our best hope of reaching net-zero emissions within the time we have left.
Batteries power much of modern life, from electric and hybrid cars to computers, medical devices and cellphones. But unless they’re made easier and cheaper to recycle, a battery waste crisis looms.
The blocks can be used to run steam turbines at power stations as a clean alternative to burning coal, and at a fraction of the price of storing energy in batteries.
Bricks turn out to be useful for storing electricity thanks to their porousness and red pigment.
Grid-scale batteries could be at least double the cost of those in electric vehicles.
Making ammonia produces almost 2% of global carbon dioxide emissions.
Don’t expect the new technology to become solar’s dark twin just yet, but it could play an important role in energy demands of the future.
Everything you need to know about pumped hydro.
Energy storage could prove an inexpensive way for power companies to handle heat waves and other times when consumers use more electricity than usual.
