WASHINGTON -- Trigeneration
- it's the "hat trick" of energy.
the name suggests, trigeneration goes one up on cogeneration, a two-step
process. Cogeneration reuses steam not
only to generate more electricity but also to heat buildings. Cogeneration is
about 60 percent efficient - that is, cogeneration captures 60 percent of the
energy from each unit of fuel it burns.
60 percent is kid stuff for trigeneration.
produces electricity for power, and steam for heat and chilled water for air
conditioning. And it squeezes 90 percent of the energy from a unit of fuel.
Louis has plans to start "trigenerating," although officials say it's
probably three to five years down the road.
we hit the trigeneration, that's the golden egg for all the units," said
Dan Dennis, general manager. "We'd like to go after that target."
