Must-run conv. supply + fluctuating renewables

Must-run conventional supply and/or baseload

Time Energy from excess renewable power

Directly usable energy from (non-excess) renewable power

Energy that has to be supplied by either conventional power or by stored energy from excess power © Siemens AG, 2011 1.

Increase of volatile power production leads to challenges in balancing production and consumption

Large-scale renewable

Challenge: Balancing production & consumption power

Decentralized generation Consumers turn to producers  Photovoltaic  Mixture between self-supply and feed-in

Volatile production  Wind power plants  Large scale solar power plants

Solutions Flexible generation technology

Grid extension

(e.g. gas turbines/ peaker, stand by, shut-down renewable)

(e.g. demand side management, smart grid)

Fluctuating energy production leads to different challenges for customers which could be solved by storage

Generator Renewable

Fossil

Transmission System Operator

Distribution System Operator

Prosumer

Different use-cases and technologies for storage Current roadblocks for breakthrough of storage

1) Technical maturity 3) Incentive schemes and regulations (e.g. fixed feed in tariff for renewable) 4) Viable alternatives available: (e.g. Fossil GT ramp-up within 30 minutes) Prosumer – blend of “producer” and “consumer”

H2 Fuel for car

 Different use-cases  Existing infrastructure can be used (turbines, pipelines)

 High potential for cost reduction  High efficiency  Low maintenance

 All components are state of the art  Efficiency – only one step from electricity to heat

 Technical maturity  Low round-trip efficiency  High capital costs

 Low economics of scale  Safety issues

 No electricity output – not feasible for positive load balancing  Infrastructure must be available
