Tula study shows electrified DSF for LDV mild hybrid diesels reduces CO2 emissions by up to 11%

Green Car Congress

liter 4-cylinder 48-volt light commercial vehicle in challenging real-world conditions. When Tula’s software strategies were implemented, an additional 11% of CO2 was eliminated compared to industry-leading hybrid powertrains. The CO 2 reduction can be achieved at a cost of only €200 ($235 USD) per vehicle.

CPT developing 48-volt electric supercharger for micro-mild hybrids

Green Car Congress

Controlled Power Technologies (CPT) is developing a 48-volt version of its 12 volt electric supercharger based on its variable torque enhancement system known as VTES. At 48 volts, a VTES electric supercharger will transform 7kW of battery power into a highly boosted charge of air for downsized gasoline and diesel engines.

Berkeley Lab copper catalyst yields high-efficiency CO2-to-fuels conversion

Green Car Congress

It is now quite common in this field to make catalysts that can produce multicarbon products from CO 2 , but those processes typically operate at high overpotentials of 1 volt to attain appreciable amounts. That extra voltage is called the overpotential; the lower the overpotential, the more efficient the catalyst.

Berkeley Lab solar-to-fuel system for CO2 to ethanol and ethylene; light-powered production of fuel via artificial photosynthesis

Green Car Congress

Reducing CO 2 to a hydrocarbon end product like ethanol or ethylene can take up to 5 volts, start to finish. This is a big step forward in the design of devices for efficient CO2 reduction and testing of new materials, and it provides a clear framework for the future advancement of fully integrated solar-driven CO 2 -reduction devices.
