Amminex City-SCR upgrade delivers gaseous ammonia for improved SCR conversion of NOx; avoiding high off-cycle emissions

Green Car Congress

The technical reason for these high “off-cycle” NO x emissions is poor NO x conversion efficiency of installed SCR systems when exhaust temperature is low. The ammonia gas is stored in solid AdAmmine material, packaged in cartridges, and is released upon heating using electric energy and/or the engine coolant. Source: Amminex.

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). P2G converts electrical energy to chemical energy in the form of hydrogen. Power-to-Gas concept.

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

Green Car Congress

It is important to state that there are several technology paths to achieve these levels of emissions, and some of them can simultaneously lower greenhouse gas emissions, such that the NO x reductions do not compete with the CO 2 reductions.

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

Green Car Congress

The MECA assessment is based on the implementation timeline presented by CARB staff at a January 2019 public workshop as well as the assumptions laid out in the CARB staff white paper released in April 2019. g/bhp-hr and a low-load cycle limit below 0.2 The cost of controlling NO x to 0.05 g/bhp-hr in 2024 and to 0.02

AMPLY Power: Top 25 US cities could save avg. 37% on fuel costs by switching to electric vehicles and buses; up to 60% with managed charging

Green Car Congress

A white paper by AMPLY Power, a company providing fleet charging as a service, finds that 25 of America’s largest metropolitan areas could save an average of 37% on fuel costs by electrifying their bus and light-duty vehicle fleets. AMPLY developed an interactive map to compare gas and electric fleet fueling costs.
