POWER TO

GAS

- Gasmotor engines are able to be operated in modulating

output control from 50 – 100 %

Synergy effects with other renewable energies

- Large scale gas storages can buffer changing

demands of power input.

- Modern electric control systems supply high

electricity quality

- Power to gas very promising

Summary

http://www.export-erneuerbare.de

- Construction and operation of modern and safe biogas

plants requires qualified and experienced staff

Summary

- Continuous training and instruction is necessary

- Biogasplants can provide cheap electricity and

heating with local raw materials and low

transportation expenses

- Multiple synergy effects with other RE

- Anaerobic digestion offers economic, social and

environmental benefits for remote areas.

Summary

- For safe operation and low maintenance rigourous

planning and contruction management is necessary.

- Regenerative energy production with biogas plants

can support weak grids – even stand alone

solutions are possible.
