Could grids negate the need for energy storage?

The potential for interconnections to minimise the need for storage across Europe looks vanishingly thin in the face of recent research.

Five future interconnection scenarios published last November as a result of a European Commission project called e-Highway2050 all accept the need for significant storage capacity in order to de-carbonise Europe’s energy system.

The 40-month-long project concluded it would be possible to achieve close to zero carbon emissions by 2050 with an investment of between €100bn and €400bn in electricity transmission infrastructure.

At the same time, however, all the models used in e-Highway2050’s research findings booklet also included an allowance of between 73GW and 113GW of energy storage, compared to 45GW in place in 2012.

“I suppose that the architects behind the project want to demonstrate the high shares of fluctuating energy can be handled,” consultant Paul-Frederik Bach told Energy Storage Report.
