Power-to-Gas
Power-to-Gas will be a key element of our new energy system
· Integrates renewable excess power that otherwise has to be cut-off
· Enables growth of generation from renewables
· Provides nearly unlimited storage capacity
· Is a means to transport power via the gas grid with lowest losses
Ø Energy Mix of Today VS Energy Mix of Tomorrow
Increased Integration of Renewables needs Storage for power
· Due to the volatile nature of renewable energy - supply and demand does not always match
· Technology to store power in large quantities is not yet available
· Innovative technologies are required to balance the gap
Characteristics of Renewables: Load profile
· Supply of renewable power is volatile and excides demand from time to time
· With more renewable energy in the system oversupply will increase
· Without storage capacities, grid operators have to balance the system and have to stop production. The surplus of renewable energy will be lost.
· PtG will enable efficient use of the excess amount of renewable energy by converting it to hydrogen and methane.
The Role of Power-to-Gas in Future Energy Supply
Motivation
· Ambitious climate goals will need innovative technologies
· PtG technology will support the future energy system by producing clean (“green”) gas from renewable power which can
· be stored to support balancing the energy grid and providing gas for backup gas fired power generation
· be used as clean fue
