Hauptversammlung 2012 28. 08. 2012, Heek Christian Grotholt Vorstandsvorsitzender 2 G Energy AG - COGENERATION 2 G Energy AGCompany & Plant Technology Presentation June 10 th, 2013 - Seoul www. 2 -g. com

FUTURE CHALLENGE The energy transition – Heading for sustainable energy technologies …into a safe power supply by renewable energies… …supported by CHP plants with best efficiencies and lowest emvironmental impact Shutting off old power plants and nuclear power… www. 2 -g. com 2

FUTURE CHALLENGES & CHANCES International • High expected availability of shale gas is likely to ensure cheap natural gas future • Spark Spread makes cogeneration operation even more economic Spark Spread • Worn-out networks • Obsolete power-plant structures • Waste treatment: In Europe only, every year around 150 million tons of organic residual materials ends up in waste -> equates ca. 36 TWh electricity p. a. -> equates ca. 6% of Germany's energy needs www. 2 -g. com 3

FUTURE CHALLENGES & CHANCES Korean Situation • Power shortage during summer time due to • old nuclear power plants • overloaded distribution networks • Increasing demand by global warming • Abundant renewable ressources available from • Landfill plants • Sewage treatment plants • Biomass treatment plants • Household waste • Animal manure etc. www. 2 -g. com 4
