the former Mukilteo, Washington, office of UniEnergy Technologies. Taxpayers invested $15 million in the development of a ground-breaking battery. Then it was given to China by the American government.
NPR’s Jovelle Tamayo Ten years ago, a group of engineers and scientists realized they were on to something significant when they assembled in a warehouse in Mukilteo, Washington. They gathered tables and chairs from various places, made room for experiments in the parking lot, and then set to work.
They were constructing a vanadium redox flow battery in accordance with a blueprint prepared by two dozen American experts working in a government lab. The batteries could be used for decades, were about the size of a refrigerator, and contained enough energy to run a house. The engineers saw people setting them down next to their air conditioners, mounting solar panels on them, and leading happy, independent lives.
Chris Howard, an engineer there for a U.S. company named UniEnergy, said of it, “It was beyond promise.” “We were observing it operating as intended and anticipated.”
Engineer Chris Howard worked at UniEnergy Technologies.

There were no longer any staff there. A Chinese company is hard at work manufacturing the batteries in Dalian, China, which is more than 5,200 miles distant.
This technology wasn’t taken from the Chinese corporation. The American Department of Energy gave it to them. Both in 2021 as part of a license transfer and initially in 2017, as part of a sublicense. According to a joint investigation by NPR and the Northwest News Network, the federal agency violated its own licensing guidelines by allowing the technology and employment to be outsourced while failing to step in on many occasions to protect American workers.
Now, China has advanced, pouring millions of dollars into the cutting-edge green technology that was meant to keep the United States and its economy in the lead.

NPR asked officials from the Gov. Jay Inslee’s office and the Department of Energy for an interview to explain how technology that cost American taxpayers millions of dollars ended up in China, but they declined. The federal agency revoked the license with the Chinese company, Dalian Rongke Power Co. Ltd., after NPR submitted department officials written questions explaining the sequence of events.
According to a written statement from the department, “DOE takes America’s manufacturing duties within its contracts extremely seriously.” “DOE will investigate all legal remedies if DOE decides that a contractor who owns a DOE-funded patent or downstream licensee is in breach of its U.S. manufacturing duties.”
A FEW U.S. COMPANIES HAVE SOUGHT LICENSES TO MAKE THE BATTERIES. According to the statement, the department is currently conducting an internal assessment of the licensing of vanadium battery technology to see whether this license and others have broken U.S. manufacturing regulations.
Several American businesses, including Forever Energy of Bellevue, Washington, have been vying for the Department of Energy’s approval to manufacture the batteries. The chief financial officer of Forever Energy, Joanne Skievaski, has been attempting to obtain a license for more than a year and referred to the department’s decision to permit overseas manufacture as “mind boggling.”
In Bellevue, Washington, Forever Energy’s chief financial officer is Joanne Skievaski. For more than a year, the business has been attempting to obtain a license from the Department of Energy to manufacture the batteries.
NPR’s Jovelle Tamayo This technology was created with government money, according to Skievaski. “It was created in a government laboratory. It is now held and deployed in China. It’s frustrating, and that’s an understatement.”
The concept for this vanadium redox battery first emerged in the basement of Pacific Northwest National Laboratory, a government laboratory three hours southwest of Seattle. In 2006, more than two dozen scientists started to have doubts about the ability of a unique combination of acid and electrolyte to store unusually high amounts of energy without deteriorating. They were proven to be accurate.
The scientists took six years and more than 15 million taxpayer dollars to develop what they thought was the ideal vanadium battery formula. Similar batteries had previously been created using vanadium, but this combination was twice as strong and didn’t seem to decay like cellphone or even car batteries do. The batteries were discovered by the researchers to be capable of charging and refilling for up to 30 years.

Pacific Northwest National Laboratory/Andrea Starr The project’s principal investigator, Gary Yang, expressed excitement at the prospect of producing the batteries outside of the laboratory. To help bring vital new technologies accomplish the market, the lab encourages scientists to exactly that. Because U.S. taxpayers funded the study, the lab and the government of the United States still control the patents.
Yang submitted his application for a manufacturing and sales license for the batteries to the Department of Energy in 2012.
Yang started UniEnergy Technologies after receiving the license from the organization. He employed scientists and engineers. But he immediately encountered problems. He claimed he was unable to get any American investors.
In an interview, Yang stated, “I contacted to practically all big investment banks; none of them (wanted to) invest in batteries. The banks demanded a return on their investments more quickly than the batteries would generate a profit.
Governor Jay Inslee of Washington, Gary Yang of UniEnergy Technologies, and Imre Gyuk, director of energy storage research in the Department of Energy’s Office of Electricity, pose side by side in 2015.
Government of Jay Inslee He said that another scientist had put him in touch with Chinese industrialist Yanhui Liu and the parent firm of Dalian Rongke Power Co. Ltd. He seized the opportunity to secure their financial support and even enlist their assistance in the production of the batteries.
Initially, UniEnergy Technologies assembled the majority of the batteries in the warehouse. Chris Howard noted that over the course of the following few years, Rongke Power began to take over an increasing amount of the production and assembly. In order to enable the business to produce the batteries in China, Yang formally sublicensed Dalian Rongke Power Co. Ltd. in 2017.
Any business can decide to produce in China. But in this instance, the guidelines are rather obvious. According to Yang’s original license, he must sell a specific quantity of batteries in the United States, and those batteries must be “substantially manufactured” locally.
Yang admitted in an interview that he didn’t do it. Few batteries were sold by UniEnergy Technologies in the United States, but not enough to satisfy its needs. The ones it did sell were produced in China, including in one instance to the U.S. Navy. Yang, however, said that over the years, neither the lab nor the department had ever questioned him or brought up any concerns.
In Bellevue, Washington, Chris Howard is now Forever Energy’s director of operations.
NPR’s Jovelle Tamayo Then, according to Howard, in 2019, representatives of UniEnergy Technologies assembled all the engineers in a meeting room. He claimed that managers informed them that they would have to spend four months at a time working in China for Rongke Power Co.
The strategy wasn’t apparent, at least to myself and other engineers, according to Howard, who is currently employed with Forever Energy.
NATIONAL Yang admits that he desired for his American engineers to work in China. But he claims that he did so because he believed Rongke Power could assist in teaching them important skills.
Yang earned his Ph.D. at the University of Connecticut despite being a Chinese citizen and having been born in China. He claimed that while he would have preferred to produce the full battery here, the U.S. lacked the necessary supply chain. He claimed that when it comes to producing and engineering utility-scale batteries, China is better advanced.
“China is ahead of the United States in this manufacturing and engineering arena,” Yang claimed. “Most people wouldn’t believe it,”
He said that he did not send his engineers and the battery to assist China abroad. He said that the engineers in that nation were supporting his UniEnergy Technologies workers and assisting him in building his batteries.
However, press reports at the time indicate that the actions benefited China. The Chinese government announced millions of dollars in funding for large-scale vanadium batteries and started a number of significant demonstration projects.
Yang was having more financial difficulties in the United States as battery work picked up in China. He consequently made a choice that would prevent the technology from remaining in the United States.
THE EU HAS STRONG REGULATIONS REGARDING WHERE COMPANIES CAN MAKE PRODUCTS. Yang gave the battery license to a Dutch-based European corporation in 2021. According to Roelof Platenkamp, the company’s founding partner, Vanadis Power initially intended to keep producing the batteries in China before opening a factory there and ultimately hoping to produce in the United States.
According to Platenkamp, the European Union has severe regulations on where businesses may manufacture their goods, therefore Vanadis Power has to produce batteries there.
In an interview with NPR, Platenkamp stated, “I have to be a European company, obviously a non-Chinese company, in Europe.
After receiving a permit from the Department of Energy to produce and market vanadium batteries, Gary Yang established UniEnergy Technologies.
NPR’s Jovelle Tamayo But similar laws exist in the United States as well. To prevent manufacturing from moving abroad, the U.S. government must approve each transfer of a license. In recent years, the United States has lost a considerable number of employment in industries where it first made headway, like solar panels, drones, and telecom equipment. Nevertheless, it appears that UniEnergy had no trouble obtaining approval when it asked for it.
On July 7, 2021, a government manager at the facility where the battery was developed received an email from a top UniEnergy Technologies official. According to emails analyzed by NPR, a UniEnergy executive claimed they were working out a contract with Vanadis and would transfer the license to them.
According to the email from UniEnergy Technologies, “We’re working to clinch a transaction with Vanadis Power and believe they have the ideal balance of technical knowledge.” “Our deal with Vanadis is approved, and we’re ready to move forward.”
In response, the government manager said he needed confirmation before transferring the license and sent an email to a second UniEnergy employee. After waiting an hour and a half for the second employee, Vanadis Power received the license.
It is unknown whether the manager or anyone else at the lab or Department of Energy thought to inquire whether Vanadis Power was an American company or whether it intended to manufacture in the U.S. during that hour and a half or after. According to Vanadis’ own website, the batteries would be produced in China.
Department representatives responded by saying they check each transfer for compliance and that new regulations put in place last summer by the Biden administration will plug gaps and keep more manufacturing in the country.
However, agency representatives admitted that because their reviews frequently depend on “good faith disclosures” from the corporations, the U.S. government might never know if firms like UniEnergy Technologies don’t come forward.
Joanne Skievaski said that she and other firm representatives frequently informed Department of Energy representatives that the UniEnergy license did not meet requirements.
NPR’s Jovelle Tamayo Government investigators said that issue has bedevilled the department for years.
The Department of Energy depended on outdated computer systems, didn’t have uniform policies across all of its labs, and lacked the resources to adequately oversee its licenses, according to the Government Accountability Office’s 2018 report ( found ).
In this instance, Forever Energy, an American business, contacted UniEnergy more than a year ago with questions over the license. Joanne Skievaski said that she and other firm representatives frequently informed department representatives that the UniEnergy license did not meet requirements. Officials from the department informed NPR in emails that it was.
How come the national lab didn’t demand American manufacturing? asked Skievaski. “It violates not just the terms of the license but also the laws of our nation.”
Skievaski expressed her hope that Forever Energy will be able to buy the license now that it has been cancelled by the Department of Energy or acquire a license that is similar to it. The business intends to start producing next year after establishing a plant there. She recoils at the notion that American engineers are incapable of meeting the challenge.
That is hogwash, she retorted. We’re prepared to use this technology.
She claims that despite this, it will be challenging for any American corporation to catch up at this stage. Dalian Rongke Power Co. Ltd. is now ranked as the world’s leading producer of vanadium redox flow batteries by industry trade reports . Skievaski is also concerned about the possibility that China would stop producing batteries once an American company is given the go-ahead to do so.
That might be improbable. According to Chinese news sources, one of the biggest battery farms the world has ever seen is set to go online. According to the reports , vanadium redux flow batteries are used throughout the entire farm.
