DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

Given the nature of wet waste resources that requires dedicated waste management practices to collect, store, treat, and dispose of the waste, shifting the waste resources from going through conventional waste management practices to utilization as feedstocks for energy production may represent an avoided cost of waste management and disposal.

Purdue, EPFL team propose Hydricity concept for integrated co-production of H2 and electricity from solar thermal energy

Green Car Congress

In the co-production mode, the co-produced hydrogen is stored for use in a turbine-based hydrogen water power (H2WP) cycle with calculated hydrogen-to-electricity efficiency of 65-70%—comparable to fuel cell efficiencies. Similarly, in standalone hydrogen mode, pressurized hydrogen is produced at efficiencies approaching ~50%.

Toyota introduces second-generation Mirai fuel cell electric vehicle as design and technology flagship

Green Car Congress

In comparison, the first-gen Mirai was FWD, and the larger stack was placed under a raised section of the passenger compartment floor. Like a Toyota hybrid vehicle, the FC also sends electricity to be stored in the battery, and the battery is also charged by the motor-generator during deceleration. Luxury Car Chassis.
