Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. But the cars and SUVs used in these situations drive more miles each year than a typical personal vehicle, contributing a higher proportion of greenhouse gases to the environment.

Researchers develop earth-abundant photocatalyst for conversion of ammonia into hydrogen

Green Car Congress

and Princeton University’s Andlinger Center for Energy and the Environment have created a scalable photocatalyst that can convert ammonia into hydrogen fuel. This result demonstrates the potential for highly efficient, electrically driven production of hydrogen from an ammonia carrier with earth-abundant transition metals.

Galp and Northvolt establish JV for lithium conversion plant in Portugal; initial annual capacity of 35,000 tons of lithium hydroxide

Green Car Congress

The plant will use a proven conversion process, leveraging recent process improvements and technologies to increase sustainability and efficiency. Additionally, the JV is seeking to enable use of green energy to power the conversion process, thereby minimizing and eventually avoiding reliance on natural gas as is the conventional approach.
