by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them.

Argonne National Laboratory’s Systems Assessment Center has released the 2020 version of the suite of GREET models and associated documentation. Vehicle technologies include conventional internal combustion engines, hybrid-electric systems, battery-electric vehicles, and fuel-cell-electric vehicles. CO 2 -derived ethanol.

The 2017 release of the suite of GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) models and associated documentation includes the following expansions and updates: Added plastic-to-fuel (PTF) pathway. Implemented new pathways for fuel cell electric medium- and heavy-duty vehicles powered by gaseous hydrogen.
Charged EVs

This tragedy involves a cast of many players—automakers, charger manufacturers, network operators, electric utilities, and often a lot more—and all need to start reading from the same script if there’s to be any hope of a happy ending. We said, “Where does charging fail 80% of the time? Let’s figure those out. Let’s categorize them.

Jesse Jenkins and his collaborators used the REPEAT energy model to project the greenhouse-gas reductions resulting from recent U.S. Jenkins: Energy systems became globalized in the middle of the 20th century and then encountered global supply shocks, like the oil embargoes of the ’70s. clean-tech legislation.

Otherwise it will become impractical to constrain atmospheric carbon dioxide, the greenhouse gas produced in burning fossil fuels, to a level that prevents the climate system from passing tipping points that lead to disastrous climate changes that spiral dynamically out of humanity’s contro l.”. That’s 18 months away.

The same commute in a plug-in hybrid electric vehicle (PHEV), meanwhile, would take a whopping 318 gallons. All told, electric miles necessitate threefold the water consumption and 17 times the water withdrawal of gasoline miles. Water consumption per MWH for a new natural gas plant is around 250 gallons per MWH.
