PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure). Heldebrant, D.,

Universal Hydrogen successfully completes first flight of hydrogen fuel cell powered regional airliner

Green Car Congress

During the second circuit over the airport, we were comfortable with the performance of the hydrogen powertrain, so we were able to throttle back the fossil fuel turbine engine to demonstrate cruise principally on hydrogen power. Deliveries will start in 2025.

DOE awards Eaton $4.9M to develop low-cost fast-charging solution; solid-state transformer, modular chargers

Green Car Congress

The US Department of Energy (DOE) has awarded power management company Eaton $4.9 million for a program to reduce the cost and complexity of deploying direct-current (DC) fast electric vehicle charging infrastructure (EVCI). Yet, current charging technology can be prohibitively expensive to deploy on a large scale.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

UC Berkeley chemists created the first such carbon-capture MOF in 2015, and subsequent versions have proved even more efficient at removing carbon dioxide from flue gases, such as those from a coal-fired power plant. The low cost of porous melamine means that the material could be deployed widely.
