Bella Coola Hydrogen Assisted Renewable Power (HARP) System
The Hydrogen Assisted Renewable Power (HARP) system project is a partnership between BC Hydro, General Electric and Powertech Labs, and is supported by the Province of British Columbia and Sustainable Development Technology Canada (SDTC). It is a demonstration project to determine the feasibility of storing excess renewable energy in remote communities to reduce the reliance on diesel generators.
The HARP project uses an electrolyzer to generate hydrogen from a renewable energy source. The system compresses and stores the hydrogen at 200 bar (20 MPa). PEM fuel cells are used to convert the hydrogen into 100 kW of electricity during peak demand periods. The demonstration project uses a micro-grid control system to balance the electrical load between the renewable energy source, diesel generation, and the power provided by the fuel cells.
