UL1973安全認證助力液流電池項目開發落地

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

UL1973涉及電站層級電池儲能系統的安全運行，模擬并評估其在制造商規定的充放電參數內承受模擬濫用條件的能力，進而評估設備、系統和組件的安全性、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已成為電池儲能系統安全的主要標準，同時還有美國國家防火協會（NFPA）發布的標準NFPA855（涵蓋安全安裝實踐）、UL9540（UL的安裝安全指南）和UL9540A（著名的誘導熱失控測試和評估電芯層級熱蔓延或熱擴散可能性）。
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.

與鋰離子電池在電池內儲存能量不同，VRFB將能量儲存在與電池堆分開的液體電解液存儲罐中，它們不會出現熱失控現象，這意味著對液流電池供應商來說通過安全測試是相對容易。

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.

"它們是相當容易通過的，但這并不意味著測試本身沒有大量熱傳感器包裹著液流電池系統"哈珀說。
“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.

雖然UL9540，特別是UL9540A主要關注消防安全，但UL1973是一個相對 "更寬泛 "的安全標準要求，這使Invinity團隊花大量時間準備該測試。
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，液流電池技術相比鋰電池技術有明顯區別（比如：安全），但也意味著需要向不太熟悉液流電池技術的測試人員解釋該技術的各個方面。
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.

換句話說，獲得認證背后的很多工作 "很難像鋰電那樣有一個標準的流程可以參考"，哈珀說。
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可以展現出液流電池技術的一些獨特優勢，特別是圍繞消防安全。
“But it allows us to really sort of emphasise some of the unique advantages of the technology, especially around fire safety.”

擁有正確的認證對獲得銀行擔保非常重要，這也使開發商更容易獲得項目融資，因此在他們選擇技術和相應供應商的決策過程中發揮了重要作用。
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.

不過，根據馬特-哈珀的說法，UL1973認證在整個開發過程中從頭到尾都很重要。
According to Matt Harper though, certifications matter from end-to-end throughout the whole development process.

"甚至在你被問到銀行擔保問題之前，如果你想在電網中安裝一個沒有這些安全認證的儲能設備，這是一個非常繁瑣的過程。它需要更長的時間來通過現場的一級許可，通過調試申請，以及其他入場資質的許可。
“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.

消防安全認證測試通過有助于圍繞 "技術的許多方面 "為行業建立信心，Kumaraswamy說。
Being able to point to verified test results helps build confidence for the industry around “many aspects of the technology,” Kumaraswamy said.

"從融資、保險等多個角度來看，確鑿地證明了技術獲得安全認證的重要性，另外這也是以一種高度差異化的方式對抗競爭，為客戶帶來好處。"
“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認證，那么當地的電氣檢查員就會看著說，'你已經滿足了國家標準，繼續吧'。"
“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’.”

考慮到更廣泛的銀行可擔保性問題，供應商需要能夠向客戶展示他們的技術具備生人全生命周期工作的能力。對于像VRFB這樣不太成熟的技術公司來說，不像鋰電池儲能系統那樣，可以輕松獲得銀行為整個系統擔保。
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，在對系統性能或系統性能的各個方面進行第三方驗證的同時，安全標準和認證開始為銀行擔保可行性建立一個案例。
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.

電池儲能系統集成商和技術供應商Fluence，通常與鋰離子電池化學制品合作，最近也宣布了其UL9540A燃燒測試的結果。
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+會議上，Fluence的增長副總裁和商業主管Kiran Kumaraswamy也指出了測試、標準和認證的不同方式。
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.
