NACFE releases guidance report on hydrogen fuel cell heavy-duty trucks

Green Car Congress

Battery electric trucks should be the baseline for hydrogen fuel cells electric vehicle (HFCEV) comparisons, rather than any internal combustion engine alternative. Stop comparisons of fill times. What is the value of a comparison on fill times? The report contains 101 figures and 230 references.

IDTechEx comments on Volkswagen’s long-term, high-manganese cathode strategy

Green Car Congress

During Volkswagen’s recent Power Day ( earlier post ), the company referred to a long-term strategy of using high-manganese cathodes for its volume segment. High-manganese cathodes could refer to several different materials, and so it is unclear as to the specific material Volkswagen were referring to.

DOE tool allows consumers to estimate localized upstream greenhouse gas emissions for EVs and PHEVs

Green Car Congress

Zip code is required because emissions are dependent upon fuels used to generate the electricity, often referred to as the grid mix, which varies by location. The tool provides some interesting comparisons. The consumer chooses the make, model, and model year of the vehicle and enters the zip code where the vehicle will be charging.

Study finds sustainable aviation fuels show up to 70% reduction in particle mass emission compared to fossil fuel

Green Car Congress

Reductions up to 70% in non-volatile particle mass emission compared to the fossil reference fuel were observed at low power settings. A comparison to in-flight emission data showed similar trends at cruise altitudes. The reduction tends to decrease with increasing power settings. during idle and taxi).

Scientists call for careful use of time scales, reference dates and statistical approaches in analyzing climate change trends to avoid distortion and hampering of response

Green Car Congress

Demonstrating that the use of different time scales, reference dates, and statistical approaches can generate highly disparate results in climate reports, scientists at the University of Alaska Anchorage argue that careful use of these tools is critical for correctly interpreting and reporting climatic trends in Alaska and other polar regions.

“Charging Station” — Is That the Location or the “Charger”?

EV Adoption

This requires simple, easy-to-understand terms without jargon, and that leverage consumer’s existing reference point of the gasoline refueling experience. In an ensuing discussion around this “charging station” reference it wasn’t clear what the author meant. 39% assumed charging station refers to the site/location and 43.2%

Researcher urges more effort on assessment of land and water impacts of oil sands production; reference point for other unconventional fuels

Green Car Congress

Bitumen production from the Canadian oil sands provides a point of reference that could be used to observe and better manage the land and water impacts of a rapid transition to unconventional fuels, suggests Dr. Sarah Jordaan of the Energy Technology Innovation Policy Research Group, Department of Earth and Planetary Sciences, Harvard University.
