The useful question is what changes for users, developers or buyers, and whether the announcement stays industry context or becomes something people can actually use.

ESS Tech, Inc. (NYSE: GWH) announced on July 30, 2026, that it has been included in TIME and Statista’s World’s Top GreenTech Companies 2026 for the second consecutive year. The annual ranking, developed in partnership with Statista, evaluates companies globally based on environmental impact, financial strength, and innovation in sustainable technologies.

Drew Buckley, CEO of ESS, attributed the recognition to the company’s team and its role in advancing non-lithium energy storage technologies. He emphasized the growing demand for solutions that balance performance, safety, sustainability, and supply chain resilience as global energy storage needs expand. Buckley highlighted ESS’s commitment to leveraging an emerging American supply chain to address customer and community demands for secure, sustainable alternatives.
