Every discharge-recharge cycle reduces the life of a battery. In fact, the higher the percentage of total available energy the battery delivers during a discharge, the greater the reduction in its ...

Scientists in Italy have looked at how flywheel storage and reversible solid oxide cells could be integrated with lithium-ion batteries in minigrids powered by solar. They found that flywheels ...

Flywheels handle short power spikes better than batteries alone; Quint pairs units with sodium-ion batteries for sustained ...

Three and a half years ago, in a column for a different website, I asked the question: will flywheel UPS ever be a viable and cost effective option? Since then, the vendor options for flywheel and ...

Although true flywheel-based kinetic energy recovery systems (KERS) never quite caught on in racing or in production hybrids, a company in Israel has been working on putting the technology to use ...

This post is part of a project to crowd-source the January issue of Forbes magazine. Click here to submit your own ideas for "Names You Need to Know in 2011." We'll put the best suggestions in the ...

Uninterruptible power supply (UPS) maker Active Power has based its business on flywheel systems which provide a short failover time. Its latest product is a departure: it is allowing batteries as a ...

It’s a not a new battery or super-hot liquid salt. But while they are not the sexiest of innovative power solutions, there is much to love about flywheels. Yes, flywheels. The energy storage ...

Typically, most all-electronic uninterruptible power supplies (UPSs) will handle loads in the tens of kVA range. Handling hundreds of kVA requires an electromechanical UPS, like a flywheel-based unit.

Earlier this year at the Detroit Auto Show, we heard about Porsche’s hybrid race car that garners energy from a flywheel, and now a consortium called Flybus has put that energy reusing technology into ...
