911r flywheel energy storage

Was the 911 GT3 R A 'flywheel hybrid'?

Hybrid street cars were becoming mainstream, and "road relevance" was repeatedly cited by Oge along with energy independence and low carbon emissions as EPA imperatives. But, like its similarly new Formula One hybrid race car cousins, this special 911 GT3 R was not a street-going hybrid. This was a "flywheel hybrid."

How does a 911 GT3 R flywheel motor work?

In the 911 GT3 R, the flywheel motor used a carbon-fiber composite flywheel with a 16-inch (406mm) diameter. Mounted in a carbon fiber box where the passenger seat would be in a road-going 911, the flywheel motor received power from, and sent power to, an 80hp (60kW) electric motor/generator at each front wheel.

Are flywheel-based hybrid energy storage systems based on compressed air energy storage?

While many papers compare different ESS technologies, only a few research , studies design and control flywheel-based hybrid energy storage systems. Recently, Zhang et al. present a hybrid energy storage system based on compressed air energy storage and FESS.

Does a flywheel store energy?

"But the technology wasn't without challenges. In general, the flywheel does not store much energy, just the braking energy," he says. "A battery is able to achieve highly stable long-term energy storage in a way that a flywheel simply cannot match.

What type of flywheel does a Porsche GT3 use?

In the GT3 R Hybrid, it was reserved for the flywheel. Porsche In the 911 GT3 R, the flywheel motor used a carbon-fiber composite flywheel with a 16-inch (406mm) diameter.

How can flywheels be more competitive to batteries?

The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
