PHOTOVOLTAIC ARRAY FOR HYDROGEN STATION

HCATT


Photovoltaic Array for H
2 Station

 

A 156 kW photovoltaic array was installed to power the hydrogen station in 2009

 

  • H2 is produced by solar power, deployable generator, or utility grid.
  • Configuration efficiency based on NREL PV Watts website.
  • 156kW PV array supports maximum load of station.  The facility has consistently made improvements and has advanced current production capability to 68kg/day.  This is enough hydrogen to refuel a fleet of 26 passenger vehicles currently in demonstration on Oahu.
  • Solar energy placed on grid when station is not operation.

 

 


 

PV Accumulated Values as of Jan 2011


  • PV array in operation for 25 months.
  • 499MWh of energy produced to either make hydrogen or offset energy consumption on petroleum based power grid.
  • 2,710kg of hydrogen produced since station opening in Nov 06; 1,815kg renewable hydrogen.
  • Approximately $80,000 savings from grid offset (station not producing/dispensing hydrogen). 
  • Rated 156kW PV array actually produced 183kW peak power.
