Compressed air project saves oil
*-
Technology conserves energy
United Press International
NEW YORK — By storing
compressed air underground
and using it to turn generators,
the electric utility industry could
save 100 million barrels of oil a
year, says a spokesman for Bat-
telle Pacific Northwest Labor
atories.
It’s already being done in
Germany and at least a dozen
American electric utilities have
compressed-air power projects
on the drawing boards, said Bat-
telle’s project manager TJ.
Daugherty.
Daugherty said the largest
proposed compressed-air pro
ject he knows about in the Un
ited States is being planned by
Maryland’s Potomac Power Co.,
which wants to store enough
compressed air in hard rock
caverns to produce 1,000 mega
watts of electricity during peak
consumption hours.
The German plant at Hun-
torff has been operating since
1977. The compressed air is
stored underground in old salt
mine caverns.
Battelle is managing a study at
Pittsfield, Ill., under a $2.2 mil
lion federal grant, to determine
the feasibility of storing com
pressed air for power genera
tion in porous rock the way na
ture stores oil and gas. The
actual work is being done by the
Houston office of Parsons
Brinckerhoff, the widely known
engineering firm, and Kaver-
nen Bau-und-Betriebs Co. of
Germany.
Using compressed air to turn
power-generating turbines, of
course, is a variant of, and a
potentially great improvement
over, the pumped storage water
power generating cycle.

project manager.
ity industry is that the gener
ators have to produce vastly
more power than is needed dur-
1 I
hours. Unless it can be sold and
transported considerable dis-
■ tances, this power just goes to
waste.
In the pumped storage cycle
the excess power is stored by us
ing it to pump water into a reser
voir. During the peak consump
tion hours, this water flows back
to the power plant by gravity
and helps turn the turbines, sav
ing vast amounts of fuel.
If air is substituted for water
in a pumped storage cycle, it has
many advantages. Water in the
quantities needed to generate
power is available at limited loca
tions. Air is everywhere and un
limited in supply and it doesn’t
need gravity to exert its force.
The capital requirements of
compressing and storing air
underground appear to be sub
stantially less than those of
pumping and storing water. But
Daugherty said no general fi
gures on these comparative costs
can be given because the costs
vary so much from site to site.
Nevertheless, he said, it can be
calculated pretty accurately that
widespread use of a compressed
air storage cycle could save the
electric utility industry at least
100 million barrels of petroleum
or coal equivalent yearly.
In comparison with the cost of
running a power plant on gas
turbines without any off-peak
hour storage,
the fuel savings migi:
order of one third.
