Lead acid batteries are the most widely deployed technology for providing stored energy for emergency power to critical DC power systems for applications including telecommunications, uninterruptible power systems (UPS), electric utility switchgear, and other stationary power systems. As the user’s applications have evolved to include more remote, uncontrolled environments, the desire to evaluate and deploy alternative energy storage technologies that may enhance life, performance, safety, economics, and reliability has become an important consideration in the strategic system engineering plans for many corporations. This paper will present an overview of various technologies that are currently considered as potential alternatives to the traditional lead acid battery approach. Key attributes of each technology will be presented and compared to other storage technologies, including lead acid, to assist the system designer in evaluating the applicability of each potential solution to the DC system requirements.
