MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

In this report, MECA provides our assessment of technologies being commercialized by component suppliers, including MECA members, to help their customers comply with future lower NO x standards. CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective (corrected)

Green Car Congress

It has now been widely demonstrated that the traditional trade-off relationship between CO 2 and NO x emissions at the tailpipe has been overcome and reductions of both pollutants can be achieved simultaneously through the use of commercially available technologies. Earlier post.). g/bhp-hr and a future LLC certification requirement.

MECA report assesses technology feasibility for heavy-duty diesel trucks to meet lower NOx standards by 2024

Green Car Congress

The Manufacturers of Emission Controls Association (MECA) released a report assessing market-ready technologies being commercialized by suppliers of emission control and efficiency components for heavy-duty diesel vehicles to meet lower intermediate standards for oxides of nitrogen (NO x ) by 2024 as a transition to final standards in 2027.

California Hydrogen Business Council says a robust P2G RD&D program should be a priority for the state

Green Car Congress

The case for using Power-to-Gas solutions to store renewable energy is compelling for a number of important use cases, according to a new white paper released by the California Hydrogen Business Council (CHBC). Constraining storage solutions to “electricity-in, electricity-out” only will increase the cost of intermittency.

Study: natural gas heavy-duty trucking fleet could benefit economy, but has mixed environmental effects

Green Car Congress

Switching from diesel fuel to natural gas may hold advantages for the US heavy-duty trucking fleet, but more needs to be done to reach the full environmental benefits, according to a new white paper released by the Institute of Transportation Studies at the University of California, Davis, and Rice University.

Montana Company Licenses Lawrence Livermore Zinc Air Fuel Cell Technology

Green Car Congress

In a 1995 paper, Cooper noted that the cost of the recovery unit is small compared with the cost of the battery because it operates continuously and hence at a lower power level than the battery. In addition, it lacks the expensive air electrode of the zinc/air battery, adding to the lower cost of the ZAFC solution.

ARB Staff Posts Expert Review Reports of the ZEV Technical Analysis

Green Car Congress

ARB staff then published a white paper summarizing possible changes to the ZEV regulation along with attachments on ZEV technology status; a 2050 GHG analysis; and complimentary policies. If so, this tracks fairly well with the most aggressive DOE and NRC (2008) cases for FCV commercialization, assuming strong policy support.
