Los Angeles Metro History of Alternative Fuels and CNG Engines

History of Metro Alternative Fuel and CNG Buses

Metro’s Alternative Fuel Fleet • First 10 CNG buses purchased in

• Purchased fleet of 333 Methanol buses 1989-1992

• AFI Policy Adopted - Purchased only CNG buses since 1992

• First fleet purchase of 294 CNG buses in 1995

• CNG Fueling Public/Private Partnerships in 1998

• 100% CNG Operation since 2011

• 2500 CNG buses; 85m+ miles/year.

• ~ 1.5 billion miles on CNG buses

1973 “Steam Bus”

• GMC New Look bus with custom built Leer Steam Engine

• Unreliable, inefficient, high emissions • “Not every idea is a good one”

New Bus Procurements

• Complete 900 bus New Flyer Delivery - October 2016.

• New RFP being released for up to 1000 40’ and 60’ buses for Metro’s fleet

– Conventional CNG or Zero Emission (most likely battery electric buses)

– Low NOx “Near Zero” CNG engines

– 90% Cleaner than current CNG engines!

– Wifi enabled for security, operating data, potentially for passengers

– Base order is for up to 300 40’ buses, and 100 60’ buses for delivery by mid 2019

– Will consider awarding a limited number as Zero Emission buses

– Expect to see similar features and amenities to current New Flyer buses

Alternative Fuel Basics – What are Hydrocarbons?

More Carbon = More Energy + More Emissions

Hydrogen: H2 High Fuel Cost, lowest emissions

Methane (CNG): CH4 Lower Fuel Cost, lower emissions

Gasoline: C6H14 Higher Fuel Cost, higher emissions

Diesel: C15H32; Higher Fuel Cost, higher emissions

Coal: C240H90O4NS Lowest Fuel Cost, highest Emissions Electricity: NA Note - Primarily sourced from hydrocarbons.

Current Outlook for CNG at Metro

• We foresee continued refinement of CNG engines, exhaust systems.

• CNG fuel prices expected to be stable – diesel fuel prices are expected to be more volatile in our region – Diesel currently $1.80/gallon – fuel cost

~$0.60/mile (price currently rising). – CNG cost $0.465/therm – total fuel cost of

~$0.40/mile (price stable ~ last 48 months)

– Since 2002, average diesel fuel price for Metro is $2.80/gallon, which equates to $0.85 per mile in our service

– Since 2002, average CNG fuel price for Metro is $0.51/therm , which, including compression, equates to $0.38/mile in our service.

Next Generation CNG

Can “Near Zero” CNG engines reduce fleet emissions? • Low NOx Engines with Renewable Natural Gas

– New Low NOx engine certified at 0.02g/bhp – 90% NOx and PM reduction possible. – 80% reduction in CO and GHG with RCNG – 0.02g/bhp NOx; PM <0.01g/bhp – Nearly equivalent to battery electric ZE in Los Angeles

• Post 2020 – We expect to see a new generation of smaller displacement CNG engines optimized for HD – Metro expects CNG to be a core part of our operation for the

foreseeable future and a transitional step to economical, proven ZE technologies

Electric Bus Program

• 5 BYD Buses Delivered in 2015 – 36,000 miles in service

– Overall performance was poor, esp. reliability, range, gradeability

– Poor operator and mechanic acceptance

– In process of negotiating a “Buy-Back” with BYD

– Potential trade in current buses for 5 BYD Articulated buses for Metro Orange Line

• 5 New Flyer All-electric Artics – Opportunity Charging at North Hollywood and

Chatsworth

– 10 minutes charging/hour of operation

– Continuous operation with no mid-day charging

– Expect deliver in Fall 2017

• Assessment of other potential electric battery bus lines is underway

Other New Bus Technologies

Looking over the horizon…

• Zero Emission Vehicles will play an increasing role

• Natural Gas and RCNG will also continue to play a big role

• Better communications and real time vehicle information

• ADA Enhancements

• Accident Avoidance Systems

• Semi-Autonomous Vehicle Operation

• Better vehicle management and tracking
