The invention provides an improved method of injecting chemicals into pipelines or facilities that transport or process oil and natural gas at remote sites. Electric power is generated from stored liquid methanol, using a direct methanol fuel cell (DMFC) alone, or else a hybrid system using both DMFC and photovoltaic (PV) solar panel in combination. This electric power is then used to operate an electric pump to inject chemicals into the high- pressure pipeline at a specific controlled rate. This pump may be an electromagnetic linearly reciprocating solenoid type design, in order to consume less power than traditional rotary electric motor pumps. Surplus electric power produced may also be used for other local equipment, unrelated to the pump. This complete system results in far less operating expense and greenhouse gas emissions than the commonly used pneumatic pumps it replaces, and more reliable year-round operation compared to solar only.
