Zero Emission BusAchievements in the USA

Zero Emission Bus Achievements:• A sustainable ZEB industry• Increasing variety in products, markets, and use cases• Technical success stories• Reliability success stories• New funding from public sources

The ZEB industry is growing

Many more in testing & development

A selection of OEMs with ZEB offerings…

More buses are on the road

• As of 2014 over 130 ZEBs are deployed nationwide - likely to double by end of 2015

• 24 battery fleets, 10 fuel cell fleets currently on the road• More ZEB miles -> more performance data, improvement

A variety of fuels & configurations are available

• In the last year ZEB offerings have covered many sectors• Configs for variety of transit agency use cases• Variety of charging solutions: depot plug-in, overhead fast

charge, inductive in-pavement

Battery Costs decreasing while energy density increasing

Source: US DOE Vehicle Technologies Office

2008: $1000/kwh, 600 Wh/L

2013: $350/kwh, 1400 Wh/L

• Between 2008 and 2013 battery costs dropped by 2/3, energy density more than doubled.

• Resulting ZEBs have longer range on fewer and cheaper batteries• Approaching DOE targets: $125/kwh and 400 Wh / liter.

• FCB reliability increasing, with per-mile maintenece costs dropping with new fuel cell bus generations

• Sunline Transit maintenance costs were lower than the CNG fleet

Public funding is increasing

As ZEB technology matures, buses are eligible for a wider pool of funding . A selection of sources:Federal Funding Sources

FTA LoNo Awarded $55m in 2015, more funding in 2016

FTA TIGGER Funded $21.2m for BEBs and FCBs 2013

FTA TIGER Funded 22 BEBs for IndyGo in 2013

California Funding Sources

CA Energy Commission

Awarded $7.3m for ZEBs in 2015, $5.8m for ZEBs in 2012.Continues for several years

Air Resources Board

New funding for large deployments (5+)$25m available in 2015, continues for several years

Incentive Programs

California ZEB vouchers $100 k - $160k per vehicle

Chicago ZEB voucher $150k per vehicle

New York State ZEB voucher $40k per vehicle

Additional Work Underway

Additional projects are breaking down barriers. In brief:• Procurement Standards. A broad industry coalition under FTA

and CTE is developing draft procurement standards to be included in the APTA White Book.

• Spare ratio requirements. Work is underway to provide guidance on the spare ratios needed to support a ZEB fleet . This would not be limited to additional vehicles, but include high-value spare components that can be swapped out between buses. • An example is a spare fuel cell that can be used in any bus within a fuel

cell bus fleet.• Altoona: several battery buses have undergone Altoona testing,

the first fuel cell bus will be tested in 2016.

Work Underway:Electric Bus Charging Standards

• EPRI and SAE are leading a task force to develop ZEB charging standards.

• Standard specs to be created for – Plug-in depot charging– Overhead conductive charging– Wireless in-ground charging

• Spec sheets will standardize three components– Physical connector– Voltage and current levels– Communication protocols

• Standardization will allow transit agencies to feel comfortable in investing in infrastructure without being concerned about verndor lock-in.

New Flyer Hi Voltage Lower Current Bus

Proterra Lower Voltage Hi Current Bus

In short…

• The ZEB market is growing into a stable industry• ZEB deployments are growing across the nation• There is a growing number of ZEB configurations, opening

opportunities with new agencies. • The industry is moving forward with technical achievements

including battery cost reductions and improved maintenance cost

• Funding sources continue to come online to grow this maturing technology.
