Energy Excelerator

Energy Excelerator was launched in 2011 by Dawn Lippert and chairman R.L. Dee as a single-family office with a stated focus on decarbonizing the built environment and transportation sectors. The firm is based in Honolulu, Hawaii, and operates from a dual-purpose structure: deploying both equity investments into early-stage companies and project finance for clean energy infrastructure. The strategy targets three overlapping verticals — climate tech, energy transition, and mobility — through direct investments, SPVs, and co-investment vehicles. The portfolio includes stakes in companies like Kairos Energy, a Hawaii-based biofuels project developer; SmartKem, a British semiconductor firm for displays; and multiple Hawaii solar-plus-storage projects. The firm reports deploying capital across the United States and parts of the Asia-Pacific region, with a concentration in Hawaii, California, and Southeast Asia. Energy Excelerator maintains a small team of fewer than 15 professionals, per public LinkedIn data. The firm has not disclosed total AUM. In 2023, it participated in a Series B round for Kairos Energy alongside other Honolulu-based investors, per Crunchbase. The firm also runs a philanthropic arm, Energy Excelerator Foundation, which supports community-focused clean energy initiatives in Hawaii. The firm's structural differentiator is its explicit linkage of family-office capital with startup incubation and local policy engagement — it functions as both investor and project catalyst, deploying capital while also working with government and utility partners to accelerate regulatory adoption of new energy technologies. This hybrid model is unusual among single-family offices, which typically separate investment from advocacy.
