Lockheed Martin Energy: emphasis on redox flow batteries

Lockheed Martin Corporation is an American aerospace, defense, arms, security, and advanced technologies company with worldwide interests. It was formed by the merger of Lockheed Corporation with Martin Marietta in March 1995. It is headquartered in North Bethesda, Maryland.

Recently, the company published a White Paper, highlighting the Lockheed Martin Energy line of business within Lockheed Martin. Lockheed Martin Energy “delivers targeted, flexible, affordable and effective energy management solutions to customers all over the world”, said the company. These solutions include long duration energy storage, federal energy solutions and nuclear instruments and controls.

Lockheed Martin Corporation:

“As the grid evolves toward a distributed model, energy storage can play a vital role in providing stability, reliability and capacity. In the earlier stages of energy storage, lithium-ion chemistry emerged as a dominant design for short-duration frequency regulation and renewables integration. Soon, lithium-ion became the most widely deployed electrochemical battery technology for stationary applications. However, as the market has since evolved to two-hour demand charges and four-hour capacity, it is clear the industry is continuously moving towards energy storage with longer and longer duration.”

“Growing market applications such as transmission and distribution deferral and renewables shifting require long-duration energy storage. In general, requirements for energy storage on the grid are becoming more challenging – requiring batteries with not only longer duration, but higher flexibility. Currently the dominant technology in the energy storage industry, lithium-ion has proven to have significant durability, flexibility, and cost limitations for long-duration storage. Technologies beyond lithium-ion can provide long-duration storage the market increasingly needs.”

This paper examines what’s driving the need for long-duration, high-durability storage and compares the capabilities of each approach. Finally, the paper finds clear advantages of redox flow batteries and details the ideal architecture and application for optimal results:

  • The storage market opportunity, focusing on the opportunity for long-duration energy storage solutions;
  • Current long-duration storage systems, comparing their relative strengths and weaknesses;
  • Characteristics of the best redox approach to utility-scale applications that ensure the most durable, scalable and cleanest energy storage system.
