Founded in 2017, RCAM Technologies is a climate tech startup dedicated to reducing the cost of renewable energy and creating domestic jobs using automated concrete manufacturing technologies. RCAM is developing and demonstrating a suite of 3D printed concrete products including wind turbine towers, anchors for floating solar, wave, and wind energy systems, and a long-duration subsea energy storage technology. In 2022, RCAM installed its 3D concrete printing system in AltaSea at the Port of Los Angeles, establishing the world&rsquo;s first facility for 3D concrete printing R&amp;D and prototyping in a port. RCAM has received funding from agencies including the&nbsp;National Science Foundation, Department of Energy, California Energy Commission, NYSERDA, and NOWRDC. RCAM received the 2021 Innovation of the Year Award from the Business Network for Offshore Wind for its modular concrete fixed bottom foundation and won &ldquo;Highest Potential Impact&rdquo; in the 2022 National Energy Storage Summit Pitchfest hosted by Lawrence Berkeley National Laboratory.
