The current volume of wastewater - the result of water forced underground to fracture rock - is estimated at 250 million barrels per day.

The result surprised even the research group: compared to pure barium titanate, the current flow was up to 1,000 times stronger.

Lithium-ion batteries are currently the preferred technology to power electric vehicles, but they're too expensive for long-duration storage

An estimated two-thirds of humanity is affected by shortages of water and in the developing world face a lack of dependable electricity.

Reducing emissions will require major policy changes such as doubling the amount of electricity generated from renewables and a shift to EVs

With the rapid reduction in the costs of renewable energy generation, there is a growing need for energy storage technologies.

The sun’s enormous energy may soon be harnessed in the dark of night following a significant advance in thermal capture technology.

Researchers have used a widespread species of blue-green algae to power a microprocessor continuously for a year—using light and water.

Hydrogen fuel cells convert hydrogen to electricity with water vapour as the only by-product, making them an attractive green alternative.

Turmeric and gold are used to create an electrode that requires 100 times less energy to efficiently convert ethanol into electricity.

In the constant search for environment-friendly alternatives to lithium-ion batteries, proton batteries are proven to have great potential.

Red bricks — some of the world’s cheapest and most familiar building materials — can be converted into energy storage units.

Hydrogen fuel cells convert hydrogen to electricity with water vapour as the only by-product, making them an attractive green alternative.

Researchers have developed a sensor made of sapphire fiber that can tolerate extreme temperatures with efficiency and emission reduction.

Researchers have optimized the design of a nuclear battery generating power from the beta decay of nickel-63, a radioactive isotope.

Researchers developed rechargeable batteries that can store up to six times more charge than ones that are currently commercially available.

New energy system makes it possible to capture solar energy, store it for up to eighteen years and release it when and where it is needed.

Molten-salt battery locks in energy for months without losing capacity and marks step toward seasonal storage of grid-scale energy.

The system hoists 30 tonne “mobile masses” into the air using excess energy. When the need arises for the power, the mass descends.

The solar project on the 17-mile-long reservoir in Hapcheon is able to generate 41.5 megawatts, enough to provide power for 60,000 people
