Master Thesis: Future Competing Battery-Chemistries in Large- Scale Battery Energy Storage Systems

Publicerad 2022-11-23

Om tjänsten


About the thesis

The electrification of wider society & industry is driving an extraordinary need for increased power generation primarily from intermittent sources. An increasing share of intermittent power generation in the energy system calls for large-scale energy storages. Batteries are one alternative frequently employed as energy storage system where Li-ion is the dominating technology. As the battery-industry grows and further potentials unravel, so does the business potential which in turn drives a technical development of bringing more chemistries to the table.  

At Vattenfall R&D we are interested in learning more about the promising battery-chemistries who will be able to compete with existing technologies in large scale deployments within the next 5-10 years.


Din bakgrund


Scope: What to do

• Review literature on battery storage and summarize a fundamental overview of generally feasible chemistries

• Involve critical stakeholders in a dialogue to summarize the view of future potential chemistries being able to complement Li-ion as large-scale battery energy storage system.

• Identify the hurdles and problems that these stakeholders see (e.g., safety aspects, capital and operating costs, critical minerals, business risk profile) and define relevant decision criteria

• Identify 2-3 possible chemistries with a significant technology-readiness level increase during the next 5-10 years.

• Interview manufacturers, suppliers and/or system integrators that work with the chosen battery chemistries

• Develop system design specifications for each chemistry for a combination of use cases and at a site specified by Vattenfall.

• Compare the different alternative chemistries for this combination of use cases at the specified site with the standard Li-ion technology currently used, based on a number of specified criteria’s, among others investment as well as running cost, environmental as well as fire risks and life-time.

• Identify whether the selected technologies is a transition technology or a longer-term technology with potential for further improvements.
