Summit Nanotech has developed and deployed one of the most reliable and efficient direct lithium extraction (DLE) technologies on the market. Its modular system and high-performance sorbent, engineered in North America and designed for commercial complexity, produce high-purity lithium from brines in Chile, Argentina, and the United States, with industry-leading water efficiency. Summit is operating a field demonstration plant in northern Chile and a multi-column system in Colorado that enables rapid testing, process development, and sorbent optimization on customer feedstocks. Summit is actively developing sorbent and technology supply agreements for projects over 5 kT/y LCE and scaling production to meet global demand.

Syzygy Plasmonics is decarbonizing the chemical industry, responsible for almost 20 percent of industrial CO2 emissions, by using light instead of combustion to drive chemical reactions. Our Rigel reactor cells channel light into high-efficiency photocatalysts, delivering a lower-carbon, lower-cost solution for chemical producers. While many startups are bringing singular technologies to market, Syzygys reactor cells are designed to support multiple reactions. Our reactors are currently available for CO2-to-eFuels projects, and for producing hydrogen from Ammonia e-Cracking or Combustion-Free Steam Methane Reforming. With additional reactions in development, Syzygy is on a path to make a broad section of chemical production sustainable. Our vision is to create a world where chemicals, fuels, and fertilizer are low-cost, carbon-neutral, and accessible to everyone. Our mission is to prevent a gigaton of CO2 from entering the atmosphere by 2040. Follow us to keep up with the latest on our journey toward a cleaner, more sustainable tomorrow!
