CoaLogix Announces the Expansion of CoalVision 360 with its NOxAssure(TM)
Program
Over 2,000 Modules of catalyst in inventory to smooth the transition to CAIR

CHARLOTTE, N.C., Feb. 2-- CoaLogix Inc., owned by
Acorn Energy, Inc. (Nasdaq: ACFN) and EnerTech Capital, today announced
NOxAssure(TM), a first of its kind fast response catalyst inventory system for
the SCR systems in coal-fired power plants.  CoaLogix's NOxAssure program
currently consists of over 2,000 modules of plate and honeycomb catalyst of various
specifications, representing over $15,000,000 of "new value" to power plants.
These catalyst are ready for purchase, regeneration and installation to meet
specific customer needs.  NOxAssure is an expansion on CoaLogix's CoalVision
360 strategy which is a blueprint for providing affordable solutions for
improving the environmental footprint and efficiency of coal-fired power
generation plants. The first initiative under this strategy was to prove the
commercial viability of catalyst regeneration. CoaLogix over the past seven
years has proven that regenerated catalyst costs 40% less than new, can be
available faster than purchasing new catalyst and ultimately reduces the
plants' environmental footprint.  To date, CoaLogix has regenerated over
11,000 modules of catalyst, many during the actual outages of coal-fired
plants.  

The announcement of the NOxAssure program could not have come at a better time
for utilities.  On December 23, 2008 the Clean Air Interstate Rule (CAIR) was
reinstated.  CAIR mandates that certain utilities run their SCR systems year
round. Many utilities have had to modify outage schedules and capital
expenditure projects to incorporate the changes that are needed to comply with
CAIR.   With the reinstatement of CAIR effective January 1, 2009, NOxAssure is
an opportunity for utilities to comply with the new regulations quickly at a
reduced cost.

Bill McMahon, CEO of CoaLogix stated, "NOxAssure is part of our ongoing effort
to provide a safety net for power plants that have been caught off guard by
the recent reinstatement of CAIR.  The requirement to run the SCR 12 months
per year in lieu of the 5 month operation will require operation during the
cold weather seasons which will have significant consequences for plants in
the northern United States. Consequently, with longer operating cycles, SCR
catalyst will need to be replaced at least twice as frequently."
