A NEW DIRECTION IN WIND ENERGY Wind Power. Redefined.™ A N EW C ATEGORY OF R ENEWABLE E NERGY : ELECTROHYDRODYNAMIC (EHD) WIND POWER

Award $4.9M over 2 years Goals Achieve 10x scale-up and complete first-ever sub-commercial scale validation of offshore power production using EHD technology and validate disruptive LCOE cost Testing University of Maine Advanced Structures & Composites Center Partner ARPA-E and Accio Energy share the goal of demonstrating and commercializing a transformative energy technology 2

NEW CATEGORY OF RENEWABLE ENERGY: ELECTROHYDRODYNAMIC (EHD) WIND POWER LOWER COST HIGHER LOGISTICS, offshore CAPACITY INSTALLATION, O&M wind farms FACTOR advantages SITING ENVIRONMENTAL advantages benefits

EHD WIND: GE GENE NERATION P ON PROCE OCESS Robust Design Manufacturing Logistics & Installation Survivable • Standard containers • Remaining panels operate • High volume, trusted • Lower non-recurring shipping if one or more is damaged processes for low cost and engineering design costs reliability • Panelized for easier • Power conversion is • Panel count defines total • Common, inexpensive installation ground based power generated materials • 20kW to many MW

EHD WIND: SCALABLE FLEXIBLE SURVIVABLE RENEWABLE  “Pop-up” transportable,  450kW concept design floating EHD wind system that deployable from the deck of a operates “near shore” cargo ship   Estimate 2 containers to Power for expeditionary or relief operations deploy 25kW

EHD WIND: REDEFINES MILITARY WIND ENERGY
