The main challenge;
the global climate - energy situation
ZEG Power
more energy – less emission!
The ZEG – technology (ZEG®)
Innovative, high efficient
co-production of
electricity and hydrogen
from hydrocarbon gases
with integrated
CO2- capture
ZEG Power
- more energy and less emissions
•
Sustainable use of carbon based fuels
– Increased life span of fossil energy reserves
•
No release of greenhouse gases
– CO2 capture an integrated part of the
technology
– No additional costs
•
Sustainable solutions for an increasing
energy demand
– Positive, varied market possibilities
– Phased technology deployment
ZEG Power AS, the company
• Established in 2008
2013
– JV between the two Norwegian research
institutes Institute for Energy Technology &
Christian Michelsen Research
• Business objective

First major up-scaling towards industrial ZEG - plants
–
–
–
–
•
Establish operational knowledge on industrially relevant ZEG-plant
Maximise system efficiency by optimised heat integration
Study ZEG-plant operational flexibility
Study long-term ZEG-plant operational stability and performance
Outcome:
– Optimised operational data forming basis for development of
commercial, small-scale standalone ZEG-plants
– Basis for further development of core ZEG-technologies and ZEGplants
Third Party Assessment
The ZEG-technology and upscaling from 50kW to 400kW
are evaluated by the German research institute ZSW
•
The concept and potential is confirmed
– “Compared with commercial available combinations of technology, the ZEG400
concept shows high potential to become cost effective even when engineering
costs for the first plant are considered. This due to the high system efficiency and
the included carbon capture technology, which leads for alternatives to high
investment and operation costs”
•
No clear showstoppers are identified
– Risks and concerns indicated in different technology elements
•
Recommended areas for development are focused in the on-going
projects and in planned work

ZEG400
- “proof of concept”
in industrial scale
Main objectives:
•Heat integration with heat transfer loop
•H2 – cycling for efficiency optimisation
•SOFC-technology
•Operation for improved lifetime
Pre-engineering phase supported by
Market and industrial opportunities
The main strengths of ZEG® for
energy production:
