A study by researchers at CU Boulder and Edinburgh Napier University finds that high-density, low-rise environments such as those found in Paris are the optimal urban form when looking to reduce greenhouse gas emissions over their whole life cycle. However, urban environmental design often neglects life cycle GHG emissions.

Tula Technology is presenting its diesel Dynamic Skip Fire (dDSF) technology ( earlier post ) at the 4 th Future Diesel Powertrain Summit China 2020 on 24-25 September 2020 in Shanghai, China. As demonstrated through testing, Tula’s dDSF technology reduces tailpipe NO x emissions by up to 66% while also reducing CO 2 emissions by up to 4%.

The internally funded advancement successfully reduced heavy-duty diesel engine nitrogen oxide (NO x ) emissions to meet the California Air Resources Board (CARB) 2027 standards. Today’s diesel engines use selective catalytic reduction (SCR) to abate NO x emissions. DEF—a 32.5 g/hp-hr standard. —Wheeler et al.

These 48-volt systems can power new, advanced energy-consuming components and can help reduce emissions and improve fuel economy and performance. Collectively, new emissions regulations will reduce tailpipe NO x limits by up to 90%, accelerating the need for global engine manufacturers to employ additional emissions reduction strategies.

Battery electric trucks should be the baseline for hydrogen fuel cells electric vehicle (HFCEV) comparisons, rather than any internal combustion engine alternative. The future acceleration of HFCEVs is likely not about the vehicles and fueling but resides mostly on the creation and distribution of the hydrogen itself.??.
