MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. The research was supported by the MIT Arthur Samberg Energy Innovation Fund. —Daniel Cohn.

MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% —Steven Barrett, professor of aeronautics and astronautics at MIT and corresponding author. increase in block fuel burn.

MIT study finds air quality co-benefits of US carbon policies can significantly offset costs, depending upon the policy

Green Car Congress

The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. times the cost of implementing a cap-and-trade program.

MIT team calculates lead emissions from avgas fuel in US contribute to ~$1B in annual damages due to IQ losses

Green Car Congress

Researchers at MIT have produced the first assessment of the annual costs of IQ losses from aircraft lead emissions in the US. Their study, published in the ACS journal Environmental Science & Technology , found that that atmospheric lead pollution attributable to leaded aviation gas (avgas) contributes to US$1.06

CMU/MIT study finds large-scale battery manufacturing will do little to reduce unit costs past a 200-300 MWh annual production level

Green Car Congress

A new techno-economic analysis by researchers at Carnegie Mellon University (CMU) and MIT has found that economies of scale for manufacturing current Li-ion batteries for light-duty EV applications (in this case, prismatic pouch NMC333-G batteries and packs) are reached quickly at around 200-300 MWh annual production. —Sakti et al.
