U.S. EPA Phase 3 Greenhouse Gas Proposal for Heavy-Duty Vehicles
A downloadable summary of the U.S. EPA announced the Phase 3 GHG proposal for heavy-duty vehicles. From 2027 to 2032, 45% reduction in CO2 emissions for light vocational vehicles and 25% for Class 8 sleeper cabs. Over half of light vocational and a quarter of sleeper cabs expected to be ZEVs by 2032.
What’s in a tire – you may be surprised
Tire manufacturers are developing the next generation tires for light- and heavy-duty vehicles to address the new performance and sustainability needs of electrified fleets.
Revised CO2 standards in Europe for heavy-duty vehicles
Europe has proposed an ambitious revision to its heavy-duty vehicle CO2 emission standards. Here’s a summary of some of the revised and new elements
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.
