Helios Climate Ventures is a venture capital firm based in Aspen, Colorado, founded in 2016 to back early-stage companies that address climate change through technology. The firm seeks investments that can generate strong financial returns alongside measurable reductions in greenhouse gas emissions, reflecting the belief that scaling effective climate solutions and achieving success in the market go hand in hand.
Focusing on a small, curated portfolio, Helios applies a hands-on approach to support founders as they navigate product development and commercialization. The team brings together expertise from industry, science, government and finance to evaluate potential investments. While the primary emphasis is on the energy storage ecosystem, the firm also invests in sustainable lithium extraction and related clean technology innovations that help decarbonize power generation and transportation.
In the field of battery technology, Helios has backed companies developing next-generation solid-state batteries for electric vehicles, advanced silicon anode materials for higher energy density and faster charging, and safer chemistries that reduce reliance on toxic or flammable components. Portfolio highlights include a solid-state battery developer partnering with major automakers, a pioneer in 100% silicon anodes scaling pilot production, and innovators creating non-toxic, affordable battery cells. Additional investments span nickel-zinc energy storage for critical systems, direct lithium extraction techniques, and low-light photovoltaic cells designed to power indoor devices without conventional batteries.
