During the past 2 years, lithium ion (Li-ion) batteries have emerged as the most widely deployed technology for new stationary energy storage projects. These batteries are typically selected due to the attractive combination of low cost and highly reputable vendors. Driven by increases in manufacturing capacity and sales volumes from the complementary EV industry, Li-ion battery pack costs have decreased dramatically. Yet, despite their popularity, Li-ion batteries are not well-suited for certain stationary storage applications.
Many non-Li-ion battery technology providers are hoping to capitalize on the weaknesses of Li-ion technology and capture a piece of this rapidly growing industry. Non-Li-ion battery providers include both startups and large, well-established corporations. While some non-Li-ion technologies have just emerged from laboratories and been introduced to the market, others have been utilized for decades. Within the stationary storage market, sodium sulfur (NaS) batteries have been widely deployed around the world. However, the high costs for NaS systems compared to alternatives combined with safety concerns due to several battery fire incidents have allowed both Li-ion and new non-Li-ion technologies to capture market share. Vendors are working to take advantage of the strengths of each of the technologies, including non-Li-ion solutions such as flow batteries, advanced lead-acid batteries, and zinc-based batteries.
This Navigant Research Leaderboard evaluates the Strategy and Execution of 13 leading non-Li-ion battery energy storage providers. These companies are rated on 12 criteria: vision; go-to-market strategy; partners; production strategy; technology; geographic reach; sales, marketing, and distribution; product performance; product quality and reliability; product portfolio; pricing; and staying power. Using Navigant Research’s proprietary Leaderboard methodology, vendors are profiled, rated, and ranked with the goal of providing industry participants with an objective assessment of these companies’ relative strengths and weaknesses in the global market for non-Li-ion batteries for grid energy storage.
