Electrical energy storage underpins modern power systems by smoothing fluctuations from variable renewable sources, enhancing grid stability and enabling portable electronics and electric transport.

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an ...

From both a regulatory and development perspective, 2018 was a significant year for the expansion of energy storage resources (ESRs). From a significant ruling of the Federal Energy Regulatory ...

Pumped storage hydropower is one of the most proven and reliable forms of large-scale energy storage in the world. | Opinion ...

An aerial photo of Hoover Dam with the Lake Mead reservoir behind. The white lines along the shore indicate the dropping water level of the reservoir as years of less than average rain fall have ...

Some electronics can bend, twist and stretch in wearable displays, biomedical applications and soft robots. While these devices' circuits have become increasingly pliable, the batteries and ...

This topic was brought to my attention when a representative from Underwriter’s Laboratories (UL) answered a question in the July/August issue of IAEI magazine. Here’s the question as it appeared in ...

It’s no secret that the energy of the future will be increasingly powered by renewables. In fact, the U.S. Energy Information Administration estimates that the share of electricity from renewables ...

Most climate action centres on getting rid of carbon dioxide. Energy Dome, an Italian startup, wants to put it to use. Its “CO 2 batteries” will store the gas under high pressure when electricity is ...

“Consumers have recognised how useful and profitable batteries are, especially in combination with solar systems, heat pumps ...

Italian researchers have looked at the potential of thermal and electrical energy storage to improve self-consumption rates in buildings when coupled with PV-powered heat pumps. They have concluded ...
