Electric marine propulsion system can save $1.7 million in fuel costs annually
An independent study for ABB by marine consultancy Deltamarin has found that the ABB Azipod electric propulsion system for ferries could save up to $1.7 million in annual fuel costs per vessel. By simulating a transit on seven existing ferry routes, researchers found that a ferry equipped with twin 10 MW mid-power range Azipod units… Read more »
Proterra CEO: Electric buses are close to inevitable
The economic case for electric transit buses has become a no-brainer, Proterra CEO Ryan Popple told Bloomberg in a recent interview. The energy cost of a typical e-bus is about 20 cents per mile, compared to about 75 cents per mile for diesel. The up-front costs for e-buses are substantially higher, but Proterra recently introduced… Read more »
Scaling EV charging infrastructure: Standards and interoperability
Sponsored by ABB. Download a PDF version of this article. A steeper growth curve for electric vehicles will depend on continuous technological development, further commercialization and practical regulatory policies. Standards and interoperability underscore all of these trends, across vehicles, charging systems and communication networks – and are a key driving force for electric vehicle adoption…. Read more »
Here we go again: German research institute claims diesels are cleaner than EVs
Anti-EV hit pieces clog the blogosphere like pickup trucks on a Texas highway, but this one sounded much more serious than the usual anonymous speculation. A respected German research institute released a study claiming EVs are dirtier than diesel – music to the ears of many in the German auto industry. “Considering Germany’s current energy… Read more »
California Air Resources Board mandates 100% zero-emission buses by 2040
The California Air Resources Board (CARB) has unanimously approved a rule that will move the state towards the goal of a 100-percent zero-emission bus fleet by 2040. Like most government programs, CARB’s Innovative Clean Transit (ICT) regulation has a long timeline – the process of proposals, meetings and workshops that led to this week’s final… Read more »
MIT wins $1.89-million DOE research grant for one-step electrochemical copper extraction from sulfur-based minerals
MIT Associate Professor of Metallurgy Antoine Allanore’s lab has received a nearly $2-million dollar grant to further develop copper collection methods from molten sulfur-based minerals using electricity. The resultant high-purity copper could be used in the production of high-quality wire used in growing markets like renewable energy and EVs. Current pyrometallurgy methods are tedious: sulfide… Read more »
California mayors call for 100% zero-emission buses
Over 35 California mayors, including the mayors of Sacramento, Los Angeles, San Francisco, Oakland and San Jose, have signed an open letter to the California Air Resources Board urging the agency to accelerate the deployment of zero-emission buses. In September, CARB is due to vote on a proposal called the Innovative Clean Transit (ICT) measure,… Read more »
Efficient Drivetrains introduces new electric drivetrain for Type A school buses
Efficient Drivetrains, Inc. (EDI), which recently announced a plan to be acquired by Cummins, has introduced its EDI PowerDrive 4000ev, suited for Type-A school buses. The Class 4 offering rounds out the company’s electric school bus solution portfolio for the North American market, which now includes Types C, D, and A. With a captive ridership… Read more »
UCS: Electric buses are cleaner in all parts of the US
Electric buses have lower global warming emissions than diesel and natural gas buses, even in cities with power grids that depend on coal plants, according to a new analysis by the Union of Concerned Scientists (UCS). The study found that, on average, electric buses produce less than half of the GHG emissions of diesel or… Read more »
