Variability in solar output creates instability on the grid, which results in poor utilization of solar resources. But Maxwell Technologies’ offers a solution in its ultracapacitors, which it says are designed to face challenges in the grid market.
The company says its ultracapacitors can help combat these challenges by providing a few seconds of reactive power in a cost-effective and smaller package size. The long life, high power and superior charge/discharge cycling of ultracapacitors make them well-suited for energy storage for firming the output of renewable installations.
The K2 series of ultracapacitor cells provide extended power availability, allowing critical information and functions to remain available during dips, sags, and outages in the main power source. The ultracapacitors are a third generation design that provides 2.7 volt operating voltage while improving Maxwell’s high performance and high reliability on a high-volume manufacturing platform. In addition, it can relieve batteries of burst power functions, thereby reducing costs and maximizing space and energy efficiency. The ultracapacitor features a cylindrical design and an electrostatic storage capability that can cycle a million charges and discharges without performance degradation. They are available in quick and easy to implement threaded terminals or in compact, weldable terminals.
The company says the series is also an good source of back-up power. It can provide extended power availability, allowing critical information and functions to remain available during dips, sags and outages in a power supply or battery change. In applications where power is needed in spikes, the K2 Series provides a “green” power solution to reduce peak power demands on the grid, batteries or generators. And the series is capable of accepting charges at the identical rate of discharge.
