California ARB awards $9.5M to Porterville to deploy 10 GreenPower electric buses and charging infrastructure
http://www.greencarcongress.com/2016/12 ... power.html

GreenPower Motor Company Inc. announced that the California Air Resources Board (CARB) has awarded $9.5 million to the City of Porterville to deploy 10 GreenPower EV350 40-foot zero-emission all-electric transit buses on all nine Porterville Transit routes, and to install the charging infrastructure including 11 charging stations.

The EV350 40-ft bus has a 320 kWh LiFePO4 battery pack providing some 185 miles of range (300 km); the two 85 kW drive motors are from Siemens. . . .

The grant award is part of California Climate Investments, a statewide program to reduce greenhouse gas emissions while providing clean-air benefits to California neighborhoods, with an emphasis on disadvantaged communities. California Climate Investments programs are funded by the Greenhouse Gas Reduction Fund using proceeds from the state’s cap-and-trade auctions. . . .

While I'm all for this, I wonder how long it will be before any AFV bus can get by on a purely commercial basis, without relying on government grants. Seems we still have a long way to go.

King County Metro Transit to purchase 120 battery-electric buses by 2020, 73 from Proterra
http://www.greencarcongress.com/2017/01/metro.html

. . . Eight of the buses are slated to go into service this year; 12 more in 2019. Up to eight of the new 40-foot battery buses will likely operate on Metro Routes 226 and 241 in Bellevue. As part of a pilot project last year, Metro began running three all-electric buses on these routes, which serve some of the county’s densest job centers, including the Microsoft campus and downtown Bellevue.

The 40-foot Catalyst buses have an estimated range of about 25 miles, with a quick charging time of just 10 minutes. Maintenance costs of all-electric buses are expected to decline versus hybrid-diesels, primarily because they have fewer moving parts.

The 73 battery-electric buses from Proterra will cost up to $55 million, starting with 20 buses totaling $15.12 million. Charging stations to support the initial orders of those buses will range from $5.5 million to $6.6 million.

Federal funding often helps pay for Metro’s new bus purchases. Last year, King County Metro received a $3.3-million grant from the Federal Transit Administration’s Low-or No-Emission Vehicle Deployment Program to help fund some new battery buses and charging stations for three buses that are in operations on the eastside of King County.

Metro will also acquire up to nine long-range electric buses from different manufacturers to test the battery technology with a range of about 140 miles. With this approximately $7-million acquisition, Metro is challenging the industry to produce buses that can travel farther. Metro also is calling on the industry to develop 60-foot long buses, better able to replace the articulated buses that make up 55 percent of its fleet. . . .

Paris tests electric driverless minibus to fight pollution:
Two electric-power EZ10 minibuses, which can carry up to six seated passengers, were put into service Monday and will be tested until early April between the Lyon and Austerlitz stations in Paris. The GPS-guided vehicle is free and will be running seven days a week.
That's an interesting approach. Here is a link to the manufacturer's website. It appears to have four-wheel steering. Heck, it even looks French!

Here is a page with details on the EZ10:

. . . The order from TEC Group covers 55 buses for Charleroi and another 35 buses for Namur. ABB will supply 4 charging stations to Charleroi and 8 charging stations for Namur. Delivery and installation will get under way this autumn. After the delivery, the TEC Group will have ordered in total 101 Volvo electric hybrids and 15 ABB charging stations.

The customer and operator, TEC Group, previously ordered 11 Volvo 7900 Electric Hybrids along with charging stations for Namur, a system that became operational in January this year. Once the 35 new buses take to the roads, 90% of Namur’s public transport will be electrified. . . .

It seems clear now that BEV buses are the electric drivetrain of choice in China with sales of 115,700 in 2016! This number represents 20% of the total bus market in China. HEV bus sailes peaked in 2013 (and disappeared in 2015) and PHEV sailes appear to have peaked in 2015 at only 23,051.

It seems China is producing about 3X as many BEV buses each year as Nissan is producing LEAFs. BYD is now the largest Li-ion battery manufacturer in the world/url] with [/url=https://ev-sales.blogspot.com/2017/01/china-buses-2016.html]8,848 MWh manufactured in 2016, almost equally split between buses and passenger cars.

It appears H2 FCV buses are an also-ran in this market, with China's largest single deployment of those buses being only 300 units.

The city bus market is already locked up for EVs, over diesel or hydrogen.

I fully expect that in ten years, there won't even be hydrogen or diesel city busses available (beyond grossly subsidized government funded experiments).

EasyMile's EZ10 is beginning a long-term trial in San Ramon:
Yahoo wrote:A pair of $250,000 autonomous buses began driving around an empty San Francisco Bay Area parking lot on Monday, preparing to move onto a local public road in California's first pilot program for a self-driving vehicle without steering wheel or human operator.
Even at the current price of a quarter-million dollars, I'm thinking this vehicle is already cheaper than its petroleum-powered alternatives. The reason is that, unlike with a private vehicle, when you eliminate the driver from a commercial vehicle, you also eliminate a huge expense. After a couple of years of operation, this vehicle should prove to be cheaper than its alternatives.

Porterville, CA orders ten 40' all-electric buses from GreenPower; option for 20 more
http://www.greencarcongress.com/2017/03 ... power.html

Canada-based GreenPower Motor Company has entered into a sales contract to supply 10 GreenPower EV350 40-foot zero-emission all-electric transit buses with the City of Porterville in California for deployment on all nine Porterville Transit routes. The order includes 11 charging systems to be installed at the maintenance facility and transit center for a total purchase price of approximately $9 million.

The funds for the acquisition were granted from the competitive California Air Resources Board (ARB) Zero-Emission Truck and Bus Pilot Program. The EV350 bus is spec’d with a 320 kWh LiFePO4 pack and a presumptive range of more than 185 miles (200 km).

The first bus is scheduled to be delivered in the fall of this year with the remaining nine buses three to four months later. . . .

Alstom and NTL launch electric Aptis as new mass transit mobility solution; four steerable wheels; Paris trials
http://www.greencarcongress.com/2017/03 ... aptis.html

Alstom and NTL presented Aptis, an innovative electric mobility solution for mass transit. Aptis’ unique and innovative design, based on that of a tram, incorporates low-floor accessibility and 360° views. Two or three large double doors enable easy on-and-off passenger flows and smooth access for wheelchairs and strollers. 95 passengers can travel on this 12-meter long bus. . . .

With four steerable wheels versus two for a bus, Aptis occupies 25% less surface area in curves. At bus stops, this minimizes the space needed to park while offering gains in available space for other vehicles.

With batteries and power systems located on the roof and the wheels situated at both ends with no overhangs, Aptis offers passengers the utterly novel concept of a 20 m2 fully low floor.

Aptis has four tires instead of six for buses, there is an air-cooling system for the motor instead of traditional water-cooling. . . .
