Why energy storage?

Future of energy systems – towards a new paradigm?

Why energy storage?

  • increased distributed energy resources increases grid variability.
  • Baseload capacities needed for grid flexibility.

 sustainable solution to emerging energy problems! Smart local grids, linking a diverse set of distributed resources across different sectors.

A battery storage system consists

  • f more than just battery cells

Battery storage systems consists of:

  • Battery storage
  • Battery module
  • Cells
  • Housing
  • Battery management

(BMS)

  • If necessary, fan and

housing

  • Inverter
  • If necessary Energy-

management system (EMS)

  • Housing, possibly with

fan / can also be container format

  • Strength
  • Weakness
  • High energy density
  • High power density
  • Long Life time
  • High efficiency
  • Low maintenance effort
  • Complex battery management
  • thermal runaway
  • Still relatively high investment costs
  • Sometimes cooling is necessary
  • Opportunities
  • Threats
  • Fully automated mass production of

electric vehicles leads to drastic cost reductions

  • No special requirements on the site
  • No gassing
  • Exploitation possibilities in a few

countries

  • Expensive high performance storage is

not necessary for stationary applications

  • Acceptance problems by safety issues

Price of lithium-Ion battery – drop of 73% since 2010.

25

Economics of Battery Storage Systems

Decreasing price trend lithium-ion batteries caused by:

  • Technological improvements

increasing efficiency.

  • Competition and economies of scale in

manufacturing industry (car companies such as Tesla, BMW, entering the market for EV sector).

  • Oversupply manufacturing companies

(EV demand lower than expected).

slide-26
SLIDE 26

Lithium-ion battery prices will fall to $73/kWh by 2030

26

Economics of Battery Storage Systems

  • Exponential growth in demand lithium-

ion batteries expected (especially due to growth EV sector).

  • Many new manufacturing plants

announced or under construction.

  • Intensified competition and high

learning rate expected to further decrease prices.

Opportunities & Challenges Battery Storage Systems

Opportunities & Challenges

  • Battery storage systems provide solution for

emerging need for grid flexibility due to increasing trend in RE and distributed energy resources.

  • ESS + PV lower LCOE than diesel gensets,

especially in remote area’s where diesel is expensive (islands Indonesia, Philippines).

  • Lithium-Ion battery systems expected to drop further

in price (1% per month).

  • New battery technologies such as Redox Flow at

launching stage, offering longer charge/discharge cycle more suitable for bigger solar PV projects. Opportunities Challenges

  • Despite price reductions, technology remains

expensive.

  • Storing energy from big solar projects would

need warehouses full of batteries due existing technology’s small charge/discharge cycle.

  • familiarity with storage technology among

utilities, regulators and financiers.

  • The need for highly skilled and experienced

technicians to maintain and operate systems correctly.

  • No solutions yet for after end of battery life-

time.
