Machine learning PODA model projects the impact of COVID-19 on US motor gasoline demand

Green Car Congress

The PODA model is a machine-learning-based model to project the US gasoline demand using COVID-19 pandemic data, government policies and demographic information. The Motor Gasoline Demand Estimation Module quantifies motor gasoline demands due to the changes in travel mobility. —Ou et al.

MIT/UC Davis professors challenge claims that ethanol production decreased gasoline prices in 2010 and 2011

Green Car Congress

Knittel/Smith results for implied gasoline price effects from elimination of ethanol for 2010 using Du/Hayes model and pooled-sample estimates. Christopher Knittel at MIT and Assoc. We encourage similar skepticism about the estimated effect of ethanol on gasoline prices generated from these models. Click to enlarge.

MIT study finds significant economic and environmental benefits from designing US LDVs to use higher octane gasoline (98 RON)

Green Car Congress

In a companion study to an SAE paper presented in April ( earlier post ), researchers at MIT have quantified the net economic and CO 2 emissions benefit that could be obtained by utilizing 98 RON gasoline in light-duty vehicles, based on reasonable assumptions for possible refinery changes and the evolution of the LDV fleet.

MIT and IEA reports take different views of the future of natural gas in transportation

Green Car Congress

MIT and the IEA both have newly released reports exploring the potential for and impact of a major expansion in global usage of natural gas, given the current re-evaluation of global supplies. emissions are reduced by around 25% relative to the use of gasoline for the same engine efficiency.
