Advanced energy storage
Using a combination of ultracapacitors and batteries in vehicle energy storage architectures can help reduce emissions and increase cost savings.
VSP News: Kolman's Korner, Episode 137 - Engine Idling
In this installment, Fleet Maintenance editor David A. Kolman visits with Jeff Brakley, senior marketing and business development manager, Maxwell Technologies, about idling diesel engines and some of the issues associated with doing this.
Energy storage: the key to enabling renewable energy
As energy demand and the drive to reduce global emissions increases, many countries are making a move to more renewable resources, like wind and solar power. However, there are a number of questions about the dependability of these alternatives.
Ultracapacitors for Start-Stop Systems in Micro-Hybrids
As more states offer incentives for the purchase of electric vehicles (EVs), governments are overlooking the benefits that alternative eco-friendly and energy efficient vehicles offer. By only providing credits for pure EVs, states are missing out on an opportunity to ignite adoption of other cars, like micro-hybrids, which also offer environmental advantages compared to traditional combustion engines.
Ultracapacitor Energy Storage: Improving Power Reliability And Efficiency Across The Grid
Ultracapacitors are power devices capable of hundreds of thousands of cycles and feature long lifetimes, making them a natural fit in grid energy storage solutions. According to Navigant Research, grid energy storage is expected to generate in excess of $68 billion in revenue from 2014 to 2024.
Feeding The Energy Appetite Of The Grid
The worldwide power grid is hungry.
Long-term energy and short-term power are the menu options. While batteries are perfect for serving up long-term energy, their specialty isn’t in meeting the grid’s fast response, rapid fire, comparatively short duration energy needs. Ultracapacitors, like batteries, are energy storage devices, but are unique in that they specialize in delivering short bursts of power in near instantaneous time frames. The grid’s changing appetite for energy (long-term) and power (short-term) are being satisfied by hybrid battery-ultracapacitor energy storage systems.

Supercapacitors continue to gain usage as more applications require storing and releasing high amounts of energy in short periods. The devices, which have two plates soaked in an electrolyte and are separated by a very thin insulator, store considerably more energy than conventional capacitors. Compared to batteries, they have lower overall storage capacity but higher energy density.
NFPA 110 Compliant Ultracapacitor-based Starting Solutions
Maxwell Technologies Generator Starting Solution (GSS) provides a fast, reliable starting solution for gensets ranging from 15 kW to 3.5 MW. The incorporation of their ultracapacitor technologies allows for up to 10 years of reliable maintenance-free starting, as there are no electrochemical cells that undergo degradation compared to lead acid batteries that have to be replaced every two years.
The Role of Ultracapacitors in Automotive Technologies
An ultracapacitor complements a primary energy source by supplementing power during periods of peak demand. They are able to quickly release or accept charge at a moment’s notice, and what an ultracapacitor lacks in storage capacity is overcompensated for by efficiency and life expectancy. They are able to quickly absorb energy, produce peak loads on demand and withstand repeated charge cycles without degradation. Essentially, they are a power storage device with an extended life expectancy.
Ultracapacitor Makers Look to Micro-Hybrid Vehicles for Growth
Ultracapacitor makers are looking to vehicle electrification as a way to increase sales, targeting the so-called "micro-hybrid" market rather than plug-in electric vehicles.
