​​Developing a MDHD ZEV Infrastructure Blueprint for the South Coast​

This report uses data from multiple sources to conduct modeling and analysis to estimate the number of future Medium- and Heavy-Duty Zero Emission Vehicles (MDHD ZEVs) deployed in the South Coast Air Quality Management District (SCAQMD) territory and their respective power and fuel requirements. Projections of future MDHD ZEV deployments in the region are estimated based on EMFAC model vehicle inventory, the current California Air Resources Board (CARB) Scoping Plan, and relevant ZEV mandates. The numbers of projected MDHD ZEVs operating in the analysis region are approximately 2,900 in the year 2025, approximately 56,000 in 2030, and approximately 129,000 in 2040. The estimated electric energy and hydrogen fuel requirements are approximately 165 MWh and 5,000 kg, respectively for the year 2025, and 8,000 MWh and 165,000 kg for 2040. The number of future MDHD electric charging stations and hydrogen fueling stations are estimated based on the amount of total fuel and electric energy needed and daily dispensing capacity limits per station. The approximate combined numbers of stations required are on the order of up to 45 stations by year 2025, on the order of 150 by 2030, and on the order of 400 by 2040. The required station numbers will vary significantly depending on a number of parameters, including MDHD ZEV deployment timelines, number of private versus shared facilities, and individual station capacities and specifications. This report also provides a map of the South Coast region, with a relative preference rating of areas for the placement of future MDHD hydrogen fueling and electric charging stations. The candidate area analysis considers existing transportation infrastructure, current MDHD vehicle driving patterns and truck stops, electric grid infrastructure, projected MDHD ZEV fuel/energy requirements, and zoning information. In addition, the report evaluates the anticipated benefits associated with MDHD ZEV deployment in the region, including reductions of GHG, criteria pollutant, and air toxics emissions, qualitative health impacts, and jobs created by investments.
