Division 48 Electrical Power Generation
Diesel and gasoline powered generators are the most common types of portable power generation, but they are polluting, noisy, and require the transportation and consumption of fossil fuels, which can be problematic in environmentally sensitive or fire-prone areas.
Portable photovoltaic (PV) generators can provide power with almost no jobsite impact, using batteries to store power for use during unfavorable weather conditions.
While not widely used today, hydrogen fuel cells are another option for low-impact portable power generation. Fuel cells have been used successfully in space and as backup power supply for buildings. They are not considered renewable however, because they rely on natural gas and other fossil fuels as a source for the hydrogen they use as fuel.
