An overview of 6 energy storage methods
Editor’s note: This article comes MaxPower Weekly, a blog from Maxwell Technologies. It is authored by Mike Wilk, Sr. Systems Engineer. Utilities and grid operators have a tremendous challenge every day—to produce enough energy to meet the ever-fluctuating demands on our electric grid. During the day there is peak demand—people, businesses and machines pull energy from the grid. […]
Ultracapacitors provide a better way to power pitch systems
For the Clipper turbine, the ultracapacitor is a drop-in replacement for batteries. Typically 18 modules replace the batteries on one turbine blade.

Advancing power storage with ultracapacitors
When considering energy storage, chances are you aren’t thinking about the pitch-control system in a wind turbine. But these systems, standard in most utility-scale turbines, include an important power-storage component. Because of the large rotors on these wind turbines, blades are exposed to wind speeds that vary from the highest point to the lowest. This…

Maxwell supercap news: 2.85V, 3,400F cell, 17% more power & 23% more energy
Maxwell Technologies introduces its newest member of its K2 family of ultracapacitors, the 2.85-Volt, 3,400-Farad cell. It expands the power range of the K2 family by 17% and the energy range by 23%, making it the most powerful cell available in the industry-standard 60-mm cylindrical form factor. It is the first cell to incorporate Maxwell’s…
Battery and ultra cap manufacturers to offer combined products
Editor’s note: This cooperation is significant. Batteries and capacitors each store electric power in different ways and with different advantages and drawbacks. Properly connecting the two would allow taking advantage of the plusses of each and thereby overcoming their drawbacks. Resulting products could be useful in cars and storing power off grid. Battery manufacturer Exide…
160V ultra cap module for wind turbine pitch control
A supplier of ultracapacitors has introduced a 160V ultracapacitor module to provide energy storage and power delivery for wind turbine pitch control, short-term uninterrupted power supply (UPS) and renewable energy systems. Primarily targeted at pitch control systems for 1.5 to 3 MW wind turbines, the 5.1 kg, 160V module provides a turnkey solution to simplify…
Ultracap bank capable of discharging 1 MW for 60 sec
Ultracapacitors are similar to batteries in that they can store energy but with a significant advantage in that they can charge and discharge quickly, in a matter of seconds. Another plus: ultracapacitors are excellent at cycling – some are rated for a million cycles. On the downside, they store less energy than batteries of similar…
125-V module OK for vehicles in Europe
Maxwell Technologies says the North American office of United Kingdom’s Vehicle Certification Agency (VCA) has granted European Economic Community (EEC)-Type Approval and Conformity of Production (CoP) clearance to Maxwell’s 125-volt Heavy Transportation Module (HTM125).
