Lithium-ion battery OEM CATL’s claim that its latest BESS product has no degradation for the first five years of use has provoked much discussion across the industry, with some sceptical of its merits.
As storage plays an increasingly central role in the energy transition, so too is the importance of managing battery degradation. Giriraj Rathore of battery storage system integrator Wärtsilä Energy Storage & Optimisation explores some of the main strategies for successful battery augmentation, a key means of offsetting the impacts of system degradation.
Optionality is key for battery storage developers and owners when considering project augmentation, leading system integrators to enhance their augmentation offering.
The battery storage sector is about to enter its first ever phase of large-scale augmentations of systems as they reach 3-5 year degradation points and there are questions over how this will pan out, Burns & McDonnell told Energy-Storage.news.
The opening up of independent system operator (ISO) services as a result of FERC 841 has led to a “huge difference” in storage dispatch strategy for merchant markets with concurrent bidding now the typical strategy.
There is a perception that “batteries cannot be long life assets”, but it depends very much on how they are designed and used, Dr Marek Kubik of Fluence has said, in a video interview with Energy-Storage.News.
The UK government’s Department of Business, Energy and Industrial Strategy (BEIS) has refused to provide any clarity over when a decision on the potential de-rating of energy storage assets within the capacity market (CM) will be made despite a senior policy advisor stating the judgement is “imminent”.
Independent accreditation and testing company DNV GL has created Battery XT, the first testing-based verification of battery lifetime for Li-on batteries.
