Exhausting Our Air: Environmental and Human Costs of Diesel Trucks

September 28, 2023 / By Daniel Flaming and Patrick Burns / Sierra Club

California’s mandates to replace diesel trucks with zero-emission electric trucks will bring cleaner air and better jobs – if they stay on track. Slow action by electric utilities and fierce opposition by trucking companies are real threats. Displacement of brick-and-mortar retail stores by online retailing and sprawling warehouses has come at the cost of climate change, bad air, low wages.

Fuel Cells for Transportation: Technical Feasibility and Economic Impacts

Fuel cells are a feasible power system technology for future transit vehicles. The advantages of fuel cells include high efficiency and extremely low vehicle emissions. Progress in fuel cell technology is moving rapidly with limited commercialization expected in this decade. Transit vehicles are a logical first application of fuel cells in transportation. Fundamental to the application of fuel cells to transit is the choice of boarded fuel. Hydrogen and methanol are the favored fuels to store on the vehicle with methanol being converted into a hydrogen rich gas on-board the vehicle. Hydrogen simplifies the fuel cell power plant at the expense of the refueling facility. Methanol simplifies the refueling facility at the expense of the vehicle fuel cell system. Depending on the vehicle mission, range and payload advantages for each fuel can be shown. The total direct and indirect employment created per $1 Billion of demand for fuel cells is 15,157 jobs. Approximately 77% of this employment is found in the manufacturing sector.
