Two UMD Companies listed in America’s top Greentech companies of 2025

TIME and Statista recently named the top 250 U.S. companies reducing environmental impact; four of these are Maryland companies of which two were established at the University of Maryland (UMD) and the Maryland Energy Innovation Institute (MEI²).

Every year, the effects of climate change become more pronounced, but so too do the contributions from an increasing number of Greentech innovators. The sustainable solutions from these Greentech innovators aim not just to replace wasteful practices with more efficient ones, but to transform the way society operates, creating innovative, commercially viable solutions that have a positive environmental impact.

This year, TIME once again partnered with Statista to rank the 250 top sustainability focused companies in the U.S. The analysis considered the positive impact, financial strength, and innovation of organizations that are developing products, services, or technologies to stop or reverse the impact of human activities on the planet.

Ion Storage Systems, a solid-state battery company offering safe, reliable and durable solutions, and InventWood, transforming wood into high-performance, sustainable building materials, both made the top 250 list this year. Both companies began in labs at the A. James Clark School of Engineering and received energy seed grants from MEI² before launching into commercial space, in Beltsville, MD (ION) and Frederick, MD (InventWood).
