UL1973安全认证助力液流电池项目开发落地

UL1973 safety certification opens doors, speeds up project development, flow battery maker Invinity says

钒液流供应商Invinity Energy最近获得了一项关键的安全认证UL1973，这可以帮助公司加快技术的市场推广，并简化原本复杂的项目开发流程。
Anglo-American flow battery provider Invinity Energy’s recent attainment of a key safety certification will open up doors for its technology and streamline complicated project development steps.

Invinity首席商务官（CCO）Matt Harper表示，虽然没有这些认证也能完成项目，但通过UL1973和NFPA855等标准的认证，可以让获得现场许可、调试和其他阶段的所需时间大大缩短。
While projects can be done without them, being certified to standards like UL1973 and NFPA855 makes the “mind numbing” process of going through site-level permitting, commissioning and other development stages much shorter, Invinity chief commercial officer (CCO) Matt Harper said.
 

Harper在上周加州举行的RE+2022活动中接受采访并表示，几天前钒氧化液流电池（VRFB）供应商Invinity宣布其第三代电池模块VS3获得UL1973认证。
Harper spoke to Energy-Storage.news at last week’s RE+ 2022 industry event in California, a few days after vanadium redox flow battery (VRFB) provider Invinity announced that its third-generation battery modules, VS3, got UL1973 certification.

 
UL1973涉及电站层级电池储能系统的安全运行，模拟并评估其在制造商规定的充放电参数内承受模拟滥用条件的能力，进而评估设备、系统和组件的安全性、可靠性和兼容性。
UL1973 concerns the safe operation of stationary battery energy storage systems, evaluating their ability to withstand simulated abuse conditions within charge and discharge parameters specified by the manufacturer.

因此UL1973已成为电池储能系统安全的主要标准，同时还有美国国家防火协会（NFPA）发布的标准NFPA855（涵盖安全安装实践）、UL9540（UL的安装安全指南）和UL9540A（著名的诱导热失控测试和评估电芯层级热蔓延或热扩散可能性）。 
As such, it has become the major standard for battery storage system safety, alongside the US National Fire Protection Association (NFPA) standard NFPA855, which covers safe installation practices, UL9540, UL’s installation safety guidelines and UL9540A, the famous test to induce thermal runaway and assess likelihood of fire spreading, or propagating, from one cell to others.

与锂离子电池在电池内储存能量不同，VRFB将能量储存在与电池堆分开的液体电解液存储罐中，它们不会出现热失控现象，这意味着对液流电池供应商来说通过安全测试是相对容易。

Unlike lithium-ion batteries which store energy inside the cells, VRFBs store energy in tanks of liquid electrolyte separately to the cell stack. They do not go into thermal runaway, which means it might be assumed going through safety tests would be relatively easy for a flow battery provider to pass through.

"它们是相当容易通过的，但这并不意味着测试本身没有大量热传感器包裹着液流电池系统"哈珀说。
“They are fairly easy to get through, but it doesn’t mean that the tests themselves don’t have this massive amount of stuff wrapped around them,” Harper said.

 
虽然UL9540，特别是UL9540A主要关注消防安全，但UL1973是一个相对 "更宽泛 "的安全标准要求，这使Invinity团队花大量时间准备该测试。 
While UL9540 and specifically UL9540A focus directly on fire safety, UL1973 is a “much broader” standard, and required the Invinity team to spend a lot of time preparing for a test that examines “every aspect of battery safety”.
 

因此，在某些方面，液流电池技术相比锂电池技术有明显区别（比如：安全），但也意味着需要向不太熟悉液流电池技术的测试人员解释该技术的各个方面。
In some ways, therefore the company benefitted from its tech having certain key differences to lithium-ion, but also meant various aspects of the technology needed to be explained to testers less familiar with the flow battery technology.

换句话说，获得认证背后的很多工作 "很难像锂电那样有一个标准的流程可以参考"，哈珀说。
 In other words, a lot of the work behind getting the certification “is less standard than what gets done by a lot of the other battery companies out there,” Harper said.

"但UL1973可以展现出液流电池技术的一些独特优势，特别是围绕消防安全。
“But it allows us to really sort of emphasise some of the unique advantages of the technology, especially around fire safety.”

拥有正确的认证对获得银行担保非常重要，这也使开发商更容易获得项目融资，因此在他们选择技术和相应供应商的决策过程中发挥了重要作用。
Having the right certifications is important for bankability, making it much easier for developers to get project financing and therefore playing a vital role in their decision-making process on selecting technologies and technology providers.

不过，根据马特-哈珀的说法，UL1973认证在整个开发过程中从头到尾都很重要。 
According to Matt Harper though, certifications matter from end-to-end throughout the whole development process.

 
"甚至在你被问到银行担保问题之前，如果你想在电网中安装一个没有这些安全认证的储能设备，这是一个非常繁琐的过程。它需要更长的时间来通过现场的一级许可，通过调试申请，以及其他入场资质的许可。
“Even before you get to questions of bankability, if you’re trying to install a battery in the grid that doesn’t have those kinds of certifications, you could do it and we’ve done it, but it’s just a mind-numbing process. It takes a lot longer to go through the site-level permitting, go through the commissioning process, to get everything signed off.

消防安全认证测试通过有助于围绕 "技术的许多方面 "为行业建立信心，Kumaraswamy说。
Being able to point to verified test results helps build confidence for the industry around “many aspects of the technology,” Kumaraswamy said.

 
"从融资、保险等多个角度来看，确凿地证明了技术获得安全认证的重要性，另外这也是以一种高度差异化的方式对抗竞争，为客户带来好处。"
“From a financing perspective, from an insurance perspective, from so many dimensions, it proves conclusively what the technology can do for you, in a safe manner and I would also say in a highly differentiated manner against competition and deliver the benefits for the customers.”

"而如果你有UL1973或UL9540认证，那么当地的电气检查员就会看着说，'你已经满足了国家标准，继续吧'。"
“Whereas if you’ve got, UL1973 or UL9540 certification, then the local electrical inspector is going to look at and say, ‘Ok, you’ve met that, you’ve met the national standard, just go ahead’.”

 
考虑到更广泛的银行可担保性问题，供应商需要能够向客户展示他们的技术具备生人全生命周期工作的能力。对于像VRFB这样不太成熟的技术公司来说，不像锂电池储能系统那样，可以轻松获得银行为整个系统担保。
To think about the broader question of bankability, providers need to be able to show customers their technology will do what it’s claimed it can do over the lifetime of the project. For companies working in a less mature technology like VRFBs, as opposed to lithium-ion batteries, there is no “magic bullet” that will make a system bankable.
 
然而，在对系统性能或系统性能的各个方面进行第三方验证的同时，安全标准和认证开始为银行担保可行性建立一个案例。
However, alongside third-party verifications of system performance or of various aspects of system performance, safety standards and certifications “start to build a case” for bankability.
 
电池储能系统集成商和技术供应商Fluence，通常与锂离子电池化学制品合作，最近也宣布了其UL9540A燃烧测试的结果。  
Battery storage system integrator and technology provider Fluence, which does typically work with lithium-ion battery chemistries, recently announced results of its UL9540A burn tests, as reported by Energy-Storage.news a few days ago.
 
在上周的RE+会议上，Fluence的增长副总裁和商业主管Kiran Kumaraswamy也指出了测试、标准和认证的不同方式。
Also speaking to the site at RE+ last week, Fluence’s VP of growth and head of commercial Kiran Kumaraswamy also pointed out the different ways in which testing, standards and certification matter.
