Energy Excelerator Expands to Include Water Tech and Cybersecurity


Honolulu-based Energy Excelerator, the nation’s largest cleantech accelerator, just announced its newest cohort of companies, which include a newly expanded focus on water tech to solar to cybersecurity. In a statement, Energy Excelerator positioned it as part of the critical innovation ecosystem that is helping Hawaii reach its goal of 100% renewables by 2045 – the first state to set such an aggressive goal.

“2015 was a big year for energy innovation. The tech community, corporates, and governments agreed that innovation is ‘mission critical’ to reaching our global clean energy goals,” says Dawn Lippert, Director and Co-founder of Energy Excelerator. “It’s exciting to be in Hawaii, at the center of it all, where innovation and deployment meet.”

With the backing of the US Navy, Department of Energy, GE Ventures and more, Energy Excelerator now has 43 companies in its portfolio and is expanding its tech deployment network deeper into Asia. They recently announced a partnership with New Zealand’s largest utility, Vector.

Energy Excelerator is one of the most active investors in cleantech – it selects and funds 15 companies a year with up up to $1M per company. To date, Energy Excelerator has awarded about $15M to portfolio companies and those companies have gone on to raise over $223M in follow-on funding and launch 14 demonstration projects in Hawaii and the Asia Pacific.

Just as this cohort is being announced, applications for next year’s class are being prepared and will open on April 25.
