Hydrogen Fuel Cell Trucks
An updated summary of available hydrogen fuel cell electric trucks and buses, their announced range and hydrogen capacity.
CARB Advanced Clean Fleets – Proposing 100% electrification of heavy duty vehicles by 2036
A summary of CARB’s latest Advanced Clean Fleets proposal for heavy-duty truck electrification as discussed in the February 2023 Workshop.
Summary of EPA MY2027 heavy-duty engine standards
The US EPA has finalized its standards for heavy duty engines starting model years 2027 and beyond. Here is a summary of the standards and a high-level comparison with California’s low NOx rule published earlier.
On hydrogen requirements for long haul trucking in the US
We show that to convert 25% of the long-haul truck fleet in the US to hydrogen fuel cell will require doubling of the total H2 demand and doubling of the renewable electricity generation in the US today.
H2 ICE truck cost of ownership vs diesel and fuel cell vehicles
Here’s an attempt at deconvoluting the cost of ownership of H2-ICE and a comparison with diesel and fuel cell vehicles.
Characterizing the in-use heavy-duty vehicle fleet
Heavy-duty vehicles cover a very wide range of applications and typical driving profiles. A one-size-fits-all approach is unlikely to work for reaching zero tailpipe emissions from this sector. Here’s a summary of the application diversity from a US viewpoint.
Meeting the HD Low NOx standards – tech update part 1
This is part 1 of 2 technology updates on pathways to meet the low NOx standards for heavy-duty vehicles set by California and being considered by the EPA for nationwide implementation starting model year 2027.
Will batteries be the limiting factor for heavy-duty electrification?
What’s your guess – how much will the battery requirement increase relative to passenger cars if we electrify the heavy-duty sector? Taking the US as an example, we navigate this question.
Preparing for Euro VII : Sub-23 nm particles
Starting with Euro 7 regulations in Europe, particles down to 10 nm will be counted and regulated, a change from the current cut-off of 23 nm, reflecting both the increasing awareness of health impact due to ultra-fine particles and also improved measurement capabilities. We give an overview of the issue.
SuperTruck II Update : Notes from the 2021 DOE Annual Merit Review
As we enter into the final lap of the SuperTruck 2 program, all teams are confident of meeting the 55% BTE and doubling-of-freight-efficiency targets. Here are the technical solutions being pursued.
