Maxwell Technologies, a developer and manufacturer of ultracapacitor-based energy storage and power delivery products, announced that its ultracapacitors have been selected by Beijing Huadian Tianren Electric Power Control Technology, a subsidiary of China Guodian Corporation. One of the five largest power producers in the country, China Guodian Corporation’s system is building the first megawatt-scale, ultracapacitor-based…

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…

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…

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…

Although there is a growing market for environmentally sensitive energy production, key challenges to widespread adoption remain. Among the most significant is creating consistent, reliable stores of energy from unpredictable natural resources such as solar and wind power. In the wind turbine market in particular, variable weather conditions create a demand for an energy storage…
