Solar Supercapacitor Generates Both Electricity and Hydrogen

Janina Lazo-Cruz — Sun, 03 Dec 2017 11:14:34 +0000

Hydrogen is a much cleaner option than other renewable energy sources, only if not derived from methane that involves carbon dioxide emission. Another limitation of hydrogen fuel cell is its feasibility to be mass produced, efficiency in energy conversion, and cost. For these reasons, a team of scientists from University of California, Los Angeles (UCLA) […]

The Electric Vehicle of the Future Could be Powered by Supercapacitors

Benji Jerew — Wed, 16 Jul 2014 16:00:43 +0000

Energy can be stored in a number of ways, from pumped hydro to supercapacitors, but you’d be unlikely to engineer pumped-hydro energy storage into an electric vehicle or smartphone. On the other hand, there are plenty of small-scale energy storage systems for electric vehicles, smartphones, and laptops. Currently, lithium-ion battery technology delivers the best balance […]

Structural Electric Vehicle Batteries Will Make Electric Vehicles More Efficient

Benji Jerew — Thu, 31 Oct 2013 21:16:38 +0000

At first, electric vehicles were no more than conventional vehicles with the conventional powertrain replaced by an electric one, but this isn’t a very efficient way of doing things. In fact, the electric vehicle is evolving quite like the conventional vehicle has evolved over the last hundred years. For example, conventional vehicles were built with […]

Thin and Flexible Glass from Penn State Suited for Ultracapacitor Applications

Ovidiu Sandru — Tue, 23 Jul 2013 15:47:26 +0000

A new type of glass developed at Penn State promises better energy storage technologies that could power future hybrid and electric cars in the future. Glass is a dielectric material, which means electrons don’t pass easily between two of its surfaces. This property makes glass (and other dielectrics) suited for capacitor applications, where its two […]

Siemens Installing First Rail Regenerative Braking Supercapacitor Storage in Portland

Benji Jerew — Fri, 07 Jun 2013 19:16:40 +0000

In order to make use of all the energy in a moving system, like a hybrid electric vehicle, for example, regenerative braking converts the forward momentum of the vehicle into electricity. Energy is never lost, but it can be wasted, that is, converted into something unusable. Conventional vehicles, when slowing down, convert kinetic energy into […]

New Supercapacitor Can Give 1MW/kg/sec of Electricity

Ovidiu Sandru — Wed, 18 Mar 2009 16:35:42 +0000

If we pursue the road towards the full electric car, we must find ourselves the energy storage that can bear at least the power of gasoline. As far as today, batteries, supercapacitors and hydrogen have been the ways to follow for powering an electric car. Of the three, the supercapacitors have a great advantage: they can charge and discharge very quickly, giving instant torque to the electric car's motor.
