“Batteries will play a central role in accelerating renewable energy deployment”

By Mari Kristine Buckholm, Smart Innovation Norway 13. April 2018

New battery technologies are expected to offer higher energy density, faster charging, extended lifetime, and lower cost – which will be demonstrated in the INVADE pilots.

As the INVADE project seeks to integrate electric vehicles and batteries to empower storage in distribution grids, the status battery technologies and prices is worth having a look at.

In general, lithium-ion battery technologies have reached a commercial phase. There are lots of battery manufacturers and system integrators, who provide battery packs or complete energy storage systems.

Declining prices

“With current technologies, the performance is good and the cost is reasonable for many business cases. However, the technology is not fully matured yet. This can be seen, e.g., in lack of standardized products and in rapid decline of prices,” explains Ari Hentunen, Research Scientist, DSc (Tech), at VTT Technical Research Centre of Finland Ltd.

He reveals that the current prices of battery packs and complete energy storage systems for stationary applications are in the order of 600 $/kWh and 1000 $/kWh, respectively. The prices have fallen on average 10% annually and are expected to further decline at a lower rate.

“The levelized cost of stored energy is decreasing as a result of lowering prices and improvements in technology, especially in improvements in cycle life and calendar life,” Hentunen points out.

Batteries in INVADE

The VTT research scientist emphasizes that batteries can provide the flexibility that future electricity systems will need to balance the fluctuating generation of solar and wind energy.

“Batteries will play a central role in accelerating renewable energy deployment,” he states. Which is why the use of batteries as flexibility sources will be demonstrated in the INVADE pilots.

“Lithium-ion battery is a versatile energy storage technology that can be used in a wide range of applications from fast-acting power quality to daily energy storage,” explains Hentunen.

Developing our future society

As huge amounts of lithium-ion batteries are needed in the ongoing shift from the use of fossil fuels towards sustainable transportation and renewable energy production, it is important to develop battery technologies even further.

“For example, the battery technologies need to be improved for large-scale adoption in transportation and storage,” notes Hentunen. He adds:

“New battery technologies are expected to offer higher energy density, faster charging, extended lifetime and safety, and lower cost.”

@INVADEH2020 : Renewable energies and electric vehicles (EVs) change the way we consume and produce electricity. It also changes the way those who manage and distribute it must think about the electricity system – to always provide the best possible service for the connected costumers. The goal of the EU funded Horizon2020 project INVADE is to greatly speed up this process, by showing that the technologies and solutions we have today, only must be connected in new ways to solve the challenges of tomorrow.

@INVADEH2020 : As part of the European Sustainable Energy Week (EUSEW), the Sustainable energy days in Albena last week was an informative event/workshop about the innovations and optimizations in the energy field the company is introducing (https://www.eusew.eu/energy-days/eu-sustainable-energy-days-albena-bulgaria). One of the projects presented was the EU Horizon2020 project INVADE (www.h2020invade.eu). Two INVADE partners were represented, Albena Resort, Bulgaria and Smart Innovation Norway. Researcher Bryan Pellerin presented INVADE to the local stakeholders and got to exchange with Albena’s partners (both hotel managers, guests and more technical people) about what the project is addressing. "This is a part of our work package 3 focused on exploitation. We also toured their facilities (farm, wine yards, biogas plant), which was very interactive and puts INVADE in context of their other sustainability activities," explains Pellerin. ( - 1 month ago)

@INVADEH2020 : In the INVADE project, a central delivery is the cloud-based Integrated INVADE platform, which will be used by the Flexibility Operator to manage #flexibility from flexibility providers and offer this to flexibility customers. It is crucial to specify how data can be sent to and from the Integrated INVADE platform through its communication platform API pilot by Pilot. You can access Deliverable 7.2 "Specification of the CP-API-functions" at https://h2020invade.eu/deliverables/ ( - 2 months ago)

The pilots have begun testing the INVADE integrated platform: “An excellent example of how we can bring flexibility and storage technology to the end-users”

In the end of May, the INVADE consortium was gathered in the Netherlands. During the two-day meeting, all five pilot owners presented their progress to the project partners. (2 months ago)
