Stationary Storage: the missing piece in a

modern electricity supply system

1 http://www.bmu.de/themen/klima-energie/erneuerbare-energien/kurzinfo/

Electricification of islands and remote locations on

the rise by replacing fossil fuels as energy source

Abating consequences of climate change requires a

shift from fossil to low-carbon options

Increase of generation from renewable energy sources

worldwide. E.g. Germany aims at covering 80% of its

power consumption in 20501 with renewables

Economic growth spurs electricity demand and peak

load; thereby stresses the grid, while acceptance for

grid expansion is limited

Bosch Storage Solutions

Idea of storage clear, but many open questions:

Bosch engaged in projects at all scales






Which technologies are best suited for

various applications?

Which requirements exist for batteries

in the various application settings?

How can a Storage Solution be

optimally designed for its purpose?

How reliable is Storage? What

maintenance is required?

How can Storage plants make money?

A lot of challenges still ahead of us, but

progress is being made Suitable reimbursement models are currently only being explored

(“Neighborhood energy trading”)

Legislative frame conditions, regulations, permissions, etc. to be adjusted

to enable the benefits of storage to unfold as part of decentralized energy

supply system

Partnerships between utilities, grid operators, industry and all other

stakeholders is key

Pilot storage projects help to promote and foster the “Energiewende” as

well as prove the benefits
