21、ected in the United States over the next decades.ZE-MHDVs are ready to expand into all regional applications and longer-range routes.Deploying energy delivery systemsa package of technology products and supportive system developments making up a recharging infrastructure that supports the introducti
22、on of ZE-MHDVsis crucial.Infrastructure deployments must keep pace with the rapid growth of ZE-MHDVs or risk slowing the acceleration of the market.Over the last few years,industry has made major commitments to build out this infrastructure.Moreover,a growing ecosystem of infrastructure suppliers an
23、d solutions are in place to support these investments and manage this transition.Nevertheless,a particular fleets choice to transition to ZE-MHDVs can be influenced by uncertainty over the availability of recharging infrastructure.Exposure to potential unforeseen costs involved in infrastructure dep
24、loyment could affect and divert a fleets pathway toward transitioning to ZE-MHDVs,despite potential advantages regarding total cost of ownership.This concern is particularly acute with respect to electric recharging infrastructure;the delivery of electrons is different from the liquid or gaseous ref
25、ueling systems fleets may be used to and involves questions regarding the pace of transportation electrification and integration into the larger electric grid.1 To assess the feasibility of infrastructure buildout at a national scale,CALSTART projected the infrastructure necessary to deliver the ele
26、ctricity needed to meet the ZE-MHDV adoption rates in 2027,2030,and 2035 set by the Global Memorandum of Understanding on Zero-Emission Medium-and Heavy-Duty Vehicles(Global MOU);these rates represent a feasible pathway to 100 percent ZE-MHDVs by 2040(CALSTART,2022b).CALSTART 1 This analysis focuses
27、 on electric infrastructure and leaves the deployment of other zero-emission refueling infrastructure for future studies;recent work has,however,considered the role of other refueling technologies within some of the duty cycles involved in these projections(CALSTART,2023a).CALSTART|Phasing in U.S.Ch
28、arging Infrastructure 3 developed a scenario in which these needs emerge based on current vehicle activity patterns and ZE-MHDV adoption trends.In keeping with CALSTARTs overall strategy toward market acceleration and transformation,it was assumed that most of this investment will be through private
29、 entities,utilizing innovative strategies many CALSTART members have shared in public discussion on the topic(CALSTART,2022a;CALSTART,2022c).This projection shows how the accelerating pace of ZE-MHDV energy needs can be managed through market-driven,overlapping,and concurrent growth of a supportive
30、ZE-MHDV ecosystem in a phased transition.Deployment concentrates first around return-to-base depot infrastructure and in regional recharging hubs within key geographies supporting the full range of regional operations,then in key corridors enabling regional hub-to-hub operations,and finally in built
31、-out networks connecting corridors to each other and to other critical infrastructure along the larger surface transportation network.This assessment was structured to build on and further detail the Drive to Zero implementation roadmap(CALSTART,2022b).The 2040 ZE-MHDV roadmaps core strategy(Figure
32、1)breaks up the activity needed to reach full sales penetration into six overlapping stages,with smart infrastructure phasing as a critical,enabling component of five of the stages.Figure 1.Drive to Zero Six-Stage Strategy(CALSTART,2022b)CALSTART|Phasing in U.S.Charging Infrastructure 4 With the who
33、 and what of the ZE-MHDV transitionwho is investing in it and the pathway they are on to 100 percent ZE-MHDVsalready known,this study analyzes where ZE-MHDVs are likely to appear,why they appear in those locations,when they will need infrastructure,and how this phased buildout process will accommoda
34、te them.This first section presents this projection,detailing the scale and pace of the transition in terms of energy delivery needs and the phases to meet those needs.Energy Needs of the U.S.ZE-MHDV Transition ZE-MHDV Adoption Rates To determine where ZE-MHDVs will appear,this analysis used project
35、ed commercial vehicle ZE-MHDV market sales from the Drive to Zero zero-emission vehicle market assessment(CALSTART,2021a).The sales estimations are based on a multifactor forecast,which includes technology readiness and viability for key MHDV duty cycles,total cost of ownership,and production scalab
36、ility inputs for the primary commercial vehicle categories.The adoption rates represent the 2040 goal of the Global MOU.Global MOU signatories have pledged to reach 100 percent new ZE-MHDV sales by 2040 and 30 percent new ZE-MHDV sales by 2030;the United States became a signatory in 2022.The Global
37、MOU,co-led by the Government of The Netherlands and Drive to Zero,also aligns with the Paris Agreement to reach net-zero by the middle of the 21st century and to drastically cut emissions to keep the rise in mean global temperature below 2.0 degrees Celsius and limited as far as possible to 1.5 degr
38、ees Celsius.This standard is aligned with the targets announced by most major global original equipment manufacturers who have set 2040 as the date by when all new vehicle sales will be zero-emission or fossil-free(CALSTART,2021a).The Global MOU adoption rates assume this transition will occur throu
39、gh a phased“beachhead”strategy with respect to market acceleration and technology adoption.In the beachhead strategy,first-mover technology applications like transit buses,cargo vans,and school buses dominate markets.From there,supportive services and a supply chain develops behind these early appli
40、cations(CALSTART,2022c).The ZE-MHDV sales rates assumed in this analysis constitute a share of the total commercial vehicle population,which is significantly higher than those proposed by certain regulatory targets.This includes the U.S.Environmental Protection Agencys(EPAs)recently proposed Phase 3
41、 ruling targets for MHDVs,as well as the Advanced Clean Trucks(ACT)rule of the California Air Resources Board(CARB)already adopted by several statesand the Advanced Clean Fleets(ACF)rule.These rates also align with other forward-looking rates CALSTART|Phasing in U.S.Charging Infrastructure 5 of adop
42、tion used in infrastructure assessments such as those from the International Council on Clean Transportation(ICCT)(ICCT,2023).Where and How Energy Needs Will Arise Using these rates,energy needs and where they will appear were projected by considering how new ZE-MHDV sales,and the infrastructure to
43、support them,would be distributed across the United States.The purpose of this projection was to show that these needs arise from the travel patterns on the existing transportation network used by commercial vehicles.In other words,while individual fleet transitions will collectively add up to a tot
44、al energy need,they will do this within a travel market with spatially differentiated and regional variations.To demonstrate this,new sales were distributed in relation to vehicle miles traveled(VMT)by commercial vehicles(Classes 38)on relevant segments of the ZE-MHDV road network,which was defined
45、as the National Highway Freight Network(NHFN)within the lower 48 U.S.states.2 Using Federal Highway Administration(FHWA)Highway Performance Management System data,commercial vehicle activity was calculated on individual road segments and then aggregated into uniform 10-square-mile travel areas(i.e.,
46、an analytic grid)across the network.VMT for travel on individual road segments was then calculated within these areas,which was used as a basis for determining new ZE-MHDV introductions by way of a scaling factor.The energy used by travel through an area vis-vis all travel on NHFN was related to the
47、 energy of potentially introduced ZE-MHDVs in that area to the total ZE-MHDVs forecasted by the Global MOU scenario,given their energy usage,typical range,and other factors.The assumption behind this approach,one of several possible currently being explored,was that the energy used to travel through
48、 each area on NHFN will be supplied in similar proportions by a share of newly introduced ZE-MHDVs in the future.3 More detailed information on the methodology is available in the Appendix.2 NHFN was used given inter-regional and inter-state commercial vehicle travel utilizes much of the freight net
49、work.Other states and territories were excluded at this time to focus on the deployment scenarios involving the majority of this network.3 This analysis assumes vehicle range and travel patterns are constant through the duration of the projection.There are indicators that these may shift and become
50、more efficient with vocational specialization among ZE-MHDVs.CALSTART|Phasing in U.S.Charging Infrastructure 6 The introduction of ZE-MHDVs across the road network then presents a consequential change in energy delivery needed to support these vehicles,both in space and over time(Figure 2).Figure 2.
