What is a Capstone turbine?

• In layman's terms, A miniature jet engine that
  runs at speeds up to 96,000 rpm and generates
  electricity and heat.
• Electrical power output 30 kW to 5MW range
• Highly Reliable
• Ultra low emissions
• Multiple fuels natural gas, propane, diesel,
  biodiesel, methane/biomass
• Simple/cost effective design
• Low maintenance

Microturbines vs Piston Engines
Capstone Microturbines Traditional Piston Engines
Ultra low emissions Local air permits and exhaust cleanup required
Low maintenance Six hours per year High maintenance Oil changes, Coolant, Spark plugs
On board digital electronics External controls without power electronics
Integrated utility protection synchronizing Requires external relays control equipment
Lightweight small footprint More than twice the weight footprint

CCHP Case StudyRonald Reagan Presidential
Library and Museum

• The Issues
• Overcome potential power supply issues and
  rolling blackouts
• Keep exhibit building containing retired Air
  Force One jet cool, comfortable, and well lit

• The Solution
• 16 C60 microturbines running on clean-burning
  natural gas supply 95 of the facilitys
  electricity
• Three 129-ton direct exhaust-fired absorption
  chillers create 387 tons of refrigeration for
  cooling
• Exhaust from the microturbines provide hot water
  to heat the pavilion

• Savings
• Over 300,000 in annual operating costs
• 823,156 incentive reduced installation cost 30

C1000 CHP

• Absorption chillers

• Cooling towers

• C1000

Hybrid Electric Vehicle Case StudyDesignLine /
Hybrid Buses

• The Issues
• Run low emission vehicles in densely populated
  areas
• Increase fleet efficiency
• Reduce maintenance
• Improve reliability

• The Solution
• The buses' Capstone turbine generates electricity
  to charge batteries, which run electric motors.
  The batteries are charged overnight and the
  turbine system recharges them when operating.
• The vehicles are fitted with remote monitoring
  which means Designline engineers can talk to the
  on-board computers monitoring performance and
  carry out diagnostic checking.

Secure Power Case StudyBoeing Data / Telecom
System

• The Issues
• Protect data and phone networks and equipment
  from grid outages
• Minimize noise and vibration
• Allow minimal environmental impact

The Capstone C30 demonstrates its small footprint
on site at Boeing.

• The Solution
• A Capstone C30 microturbine was installed in a
  pre-existing enclosure near the buildings
  loading dock
• The natural gas powered microturbine provides
  electric power 24x7 to the network and equipment
• The microturbine ensures uninterrupted service in
  the event of a grid power outage
• The Capstone technology was preferred over UPS
  batteries and genset engines due to their noise,
  emissions and vibrations

Installation was simple, with the turbine placed
in an existing enclosure.
