Presented at Nordic Green II conference, April 2010

1. Cleaning of exhaust from ships engines by
use of Cool Flame
State of the art technology - meeting maritime emission restrictions

2. Value proposition
• Increased awareness and restrictions on emissions from ships engines (NOx, particles/soot
and sulphur)
• Main focus on harbours incl those with high population density, and coastal waters
• A new proven cool flame technology for significant reductions of NOx has recently been
demonstrated.
• The technology handles NOx in different kinds of fuels incl heavy/bunkers oil, and has
potential to handle particles/soot and sulphur as well.
• Future markets include maritime, large diesel engines in trucks and heavy duty, oil companies
/ refineries and waste treatment

3. A few facts
• Exhaust Gas Recirculation (EGR) is a promising cleaning technology for ships engines, but
with technical challenges so far
• CFT controls the exclusive rights to commercialize the patented “cool flame” conversion
technology
• A test project involving the Norwegian maritime institute Marintek and Rolls Royce recently
demonstrated that the cool flame concept reduces NOx emissions significantly
• The new technology is superior on part loads, typically for ferries and supply vessels, and for
ships using heavy fuels.

5. Testing on Rolls Royce ships engine
• Testing at Marintek
• Full scale Rolls Royce diesel engine
• 20 kW cold flame generator
• Control system delivered by Marintek
• Testing done with both heavy fuel and marine gas oil.

6. Testing results
• First tests without any optimalisation or tuning
• Engine tested at 25, 50 and 75 % load with up to 20 % EGR
• 50 % reduction in NOx, even at 75% load with only 2-4 % penalty in fuel
consumption
• Technology feasible for retro fitting as well as for new ships under construction

7. Strategy
• Go to market with current maritime system:
– First phase Scandinavia, served from a Norwegian production base
– Facilitate US introduction, based on JV for production and sales

8. The first full scale cool flame system to be installed later this year in a vessel
operating in the Norwegian fjords
