Abstract
This article focuses on the battle for dominance between various battery technologies in the residential grid storage market (< 10 KWh) in the context of residential energy systems and the related home energy management systems. We focus on five major battery technologies that are available in the market (lithium-based batteries, lead-based batteries, flow batteries, nickel-based batteries, and sodium-based batteries). Based on a literature review and expert interviews, we study the factors for technology success in the residential grid storage market. By applying the best worst method (BWM), we assign the relative importance to the factors and predict which technology will have the highest chance of achieving success. We compare this to the technology that now has the highest market share and conclude that BWM is a useful method to indicate technology dominance in this market.
