Battery storage system security was on the high of the agenda for a lot of distributors and their prospects at ees Europe final week.

{The electrical} energy storage commerce occasion passed off alongside Intersolar Europe and different strands referring to electric autos (EVs) and different good and clear energy trade sectors and applied sciences, at Messe Munchen in Munich, Germany.

Whereas there have been many attention-grabbing merchandise on present and numerous large image matters mentioned – like the necessity for coherent policy strategies at EU level on energy storage and the continued provide chain crunch – numerous sources commented that the lithium battery storage trade’s must reassure stakeholders on the subject of fireplace security is paramount.

“As a way to actually play an necessary position in our energy and skill, future batteries must be protected. It’s dangerous for the trade if persons are involved about battery security,” Kai-Philip Kairies of battery analytics specialist ACCURE Battery Intelligence tells Energy-Storage.information.

ACCURE’s software program may help monitor and assess how batteries in EVs and battery energy storage techniques (BESS) are performing, how they’re growing old and the way safely they’re working. Of these three primary options of the analytics suite, security has gotten probably the most consideration recently, Kairies, a battery expert-turned startup CEO, says.

There have been some “excessive profile failures,” that embody the fireplace at Tesla’s Victorian Big Battery in Australia and the overheating incident at Moss Landing Energy Storage Facility in California: respectively the largest BESS tasks in Australia and the world.

Most just lately there was additionally hearth reported at a 10MW/40MWh BESS installed for utility Salt River Project (SRP) in Arizona. Germany’s dwelling energy storage system market can be quickly rising and Kairies says he is aware of of 5 fires at residential techniques reported up to now month alone.

Whereas fortunately it seems that nobody has been injured by any of these incidents they usually stay uncommon relative to the sheer volumes of battery storage being put in all over the world, nobody — least of all prospects or most of the people — will be taking them calmly.

Battery storage producer Saft has been delivering containerised techniques to international markets since 2010. It has by no means skilled any critical failures of apparatus which have precipitated fires, a monitor report that the corporate’s VP for improvements and options, Michael Lippert, stated it’s pleased with.

Nonetheless, there’s nonetheless a possible danger concerned and one ought to “by no means say by no means” relating to security assessments. Lippert says that for Saft, important security concerns wanted to be thought of holistically and in-built from the very begin of labor to design the corporate’s grid-scale battery product, Intensium Max.

A method through which Saft’s strategy might differ from its rivals is that the Intensium Max is a standardised, repeatable product that doesn’t basically change in design from venture to venture.

“From the very starting, we’ve got made a danger evaluation of any attainable danger. This consists of issues just like the impact of the cooling system, we’ll embody humidity resulting from condensation, for instance, which is a danger as a result of in a 1500 Volt system, any humidity can create leaking energy,” Lippert says.

“We make it possible for earlier than you open your [container] door, we set the temperature past the condensation level. So, there are various issues we’ve got thought by to start with in the direction of [enhancing] functionalities, but in addition security.”

Saft’s system design integrates a mixture of detection techniques, hearth suppression and hazard administration that Lippert claims is “fairly distinctive on this planet”.

Intensium Max, the constructing blocks of all Saft’s tasks, comprises two unbiased hearth suppression techniques. The corporate has additionally realized, from seeing incidents happen at different makers’ tasks, that there’s a want for administration of the gases that may trigger explosions if constructed up inside containers.

“We pay lots of consideration to creating positive that the operator, but in addition hearth brigades that may intervene are aware of these gadgets they usually have the instruments to make the suitable resolution. Which suggests they don’t must open the container to see what is occurring, they’ve the coaching, they usually have the diagnostic instruments outdoors to see the temperature, to see whether or not there’s an explosive environment.”

Evolving security applied sciences

INTILION, a battery storage producer headquartered in Germany, was unveiling a brand new prototype BESS for the business and industrial (C&I) market, with an inbuilt hearth security function.

The numerous benefits that lithium-ion batteries have, additionally include “attribute hearth and explosion dangers,” which imply a lithium hearth can’t be extinguished, INTILION product supervisor Martin Peters says.

There are three primary causes of fires: electrical dangers from overvoltage, overcurrent or overheating, thermal dangers from excessive temperatures outdoors the battery system and mechanical dangers that come from bodily injury or manufacturing defects which may’t be readily recognized externally.

“Perhaps over time of utilization, you’ve gotten some points within the cells. Dendrites on the plates may very well be growing, resulting in a cell inner brief circuit, which then results in thermal runaway after which propagation.”

Within the German market, battery techniques for indoor use want to fulfill certification requirements set by VDE. These embody necessities that no hearth can unfold or propagate between neighbouring battery modules and that there ought to be no flames outdoors the module.  

INTILION has designed an extra housing to go round every module, with calculated air channels that route any gases launched in an outlined method. The gasoline is subsequently compressed sufficient to not be flammable, and the gases are vented from the entrance of the unit.

The prototype has been licensed by a laboratory in Germany. Peters says the fireplace danger from lithium batteries can’t be utterly eradicated, however the injury will be restricted to only one module. The INTILION system additionally features a tray to gather any leaked electrolyte, stopping contamination of groundwater.

As soon as techniques are literally within the subject, battery knowledge will be an efficient instrument in preventive upkeep, ACCURE’s Kai-Philipp Kairies says.

“Each battery has a BMS, a battery administration system, that generates some knowledge like voltage, present and temperature and we use that knowledge to mainly reverse engineer what’s taking place inside the battery,” Kairies says.

There are particular “interior states” of battery well being that may’t instantly be measured, will be calculated. Relying on how these interior states develop over time, ACCURE is ready to choose if a battery module or cell’s efficiency is wholesome, and much like the remainder of the pack.

If the analytics software program signifies that one battery reveals indications of plating, for instance, that battery will be pulled out of operation earlier than it turns into harmful. With over 1.5GWh of property beneath administration throughout the EV and ESS sectors, ACCURE proves this may be performed at scale, Kairies says, making certain the security of this and the subsequent era of lithium battery storage techniques.

No such bulletins from main tasks have surfaced in Europe just lately however record-high inflation may make this extra doubtless.

Simply final week, Norwegian startup FREYR Battery announced it would go ahead with construction of the primary of a pipeline of almost 100GWh of manufacturing amenities.

Alongside the ramp-up of Europe’s home lithium-ion battery manufacturing capability, the pick-up in deployments from 2028 onwards that Delta-EE is anticipating could also be helped by different battery applied sciences.

“Options to lithium which can be much less suited to mobility (sodium, zinc, iron and many others) are prone to change into extra aggressive for stationary storage, whereas non-battery storage can be rising (from a small base),” Ferris mentioned.

He added that he anticipated movement batteries to search out aggressive niches that may contribute to the pick-up in development, however didn’t count on the provision of second life batteries to materially affect forecasts till the 2030s.

Talking on the findings extra usually, Ferris added: “Nice Britain and Germany are main the best way, however their wants may improve as renewables targets are revised upwards. As a peninsula, Spain is prone to require additional development, particularly if rising temperatures pressure the reliability of pumped hydro.”
