EnerG2 Raises $3.5M More

Seattle-based EnerG2, an advanced materials and energy storage company, has raised $3.5 million in new equity financing from an undisclosed investor, according to a regulatory filing. The company, led by CEO Rick Luebbe, develops nano-scale materials to make better ultracapacitors for electric and hybrid vehicles and other applications. EnerG2 spun out of the University of Washington and raised $8.5 million led by OVP Venture Partners and Firelake Capital in 2008. Last August, the company won a $21.3 million grant from the U.S. Department of Energy to build a manufacturing plant in Albany, OR.
