Eric Dresselhuys, CEO of ESS, Makes the Case for Iron-Flow Batteries

An interview about the politics of energy storage — and whether different technologies can help

While in Anaheim for RE+ last week, I met with Eric Dresselhuys, CEO of long duration iron-flow battery storage manufacturer ESS Inc. We chatted about battery fires, community buy-in, and the future of China policy. I came in expecting optimism and left feeling we need a lot more conversations like this one.

The following is an abridged version of our conversation that has been edited for clarity.

How does your product address the opinion that battery storage has a buy-in problem?

It’s not so much an opinion as just reporting the obvious, which is that lithium-ion batteries on the grid have a buy-in problem. Maybe if you’re in rural western Australia nobody cares because there are no human beings around, but if you look at the need for energy storage to facilitate the energy transition, it’s pretty clear we have to put batteries all over the place and specifically close to where human beings live. And that’s a problem.

Can iron-flow help solve that problem? I think unequivocally we can. It’s a very different architecture. It’s a battery that’s really designed from the beginning to operate as a grid backup battery. If you go back to look at lithium, it was never designed to go onto the grid. It was designed to go into camcorders, phones. This is not the technology I think anybody would’ve picked for the grid if they had started from scratch.

Are you seeing any change in demand for your product from protests over lithium battery projects?

I think it’s the old gag of all politics are local. The politics of siting is a local problem. What’s simultaneously true is adoption of storage on the grid is growing at a phenomenally high rate. And yet there are stories [about opposition] all over the place. There was just one up in Marin County, California, where the community said it’s in an area adjacent to wetlands. And they said you know what? We’re just not going to put a–

But are these communities opposed to lithium storage actually choosing iron-flow over these projects, or are they just saying no to any development?

Right now, they’re just saying no. The communities are not going to solve the problem. They’re going to tell you what is unacceptable and it’s going to be somebody else’s job to solve the problem.

I’ll use Schiphol Airport in Amsterdam [as an example]. They said, we have thousands of gallons of jet fuel laying around. And people. And airplanes. We can’t put a lithium battery out here. So they’re using an iron-flow and sought out a non-lithium battery to solve their energy storage problems because it was safer.

China policy looms large over the future of U.S. battery supplies. What do you think the final endgame will be of our approach to China’s dominance in this business segment?

It’s a great question that I don’t think I know the answer to. I think the next step is to try and get the playing field somewhat level. The amount of subsidy that goes into renewables in general and batteries in particular in China is daunting. People talk about the IRA and all these things as if it’s a lot of money, but it’s a pittance compared to what China is putting in.

Getting the playing field a little more level in the short term through a combination of incentives here and tariffs coming on will be a next step. Until we get carbon accounting — cradle-to-grave carbon accounting — it’ll be hard to get things totally level because in the U.S. we enforce environmental laws and we don’t employ prison labor to build [these] things. Until we get that full ESG accounting, I think there’s going to be some limitation.

Okay one fun question – what was the last song you listened to? Keeping ‘em honest here at Heatmap News.

Meta’s Bacterial Mystery Could Poison the Data Center Well

Water pollution in Wyoming has big implications for the future of data center development.

Did a Meta data center introduce a rare, dangerous bacteria into the sewers system of Wyoming’s capitol city? It’s an environmental pollution mystery with an answer that could decide the future of American AI infrastructure development.

Our drama begins in Cheyenne, Wyoming, where the city’s board of public utilities just wrapped up a lengthy investigation into the presence of Cupriavidus gilardii, a potentially lethal bacteria resistant to heavy metals, in the city’s wastewater treatment systems. Apparently, in February, board staff detected the contamination and shut off public access to the city’s water reuse system, a supply of treated non-potable water fed with treated wastewater and used for lawns, athletic fields, and other green spaces. Officials were worried that spraying this water could release into the environment a bacteria found to cause fatal health outcomes in immunocompromised or elderly people who are infected by it.

How Big of a Problem Is Data Center Noise?

A conversation with Ross Marchard of the Taxpayers Protection Alliance

The Q&A subject.

This week’s conversation is with Ross Marchard, executive director for the Taxpayers Protection Alliance, a center-right advocacy group that focuses on what it sees are onerous policies potentially hindering responsible collection and use of tax dollars. TPA’s position on AI clearly skews pro-free market, as they’ve recently defended Anthropic from Trump administration attacks. TPA also recently took on the mantle of defending data centers from noise complaints, publishing a paper on Tuesday “debunking myths about data centers being excessively noisy.” The paper references various analyses of data centers by state legislators and local regulators to argue that claims the sector is generally noisy are false.

I asked TPA’s executive director to chat with me about why and how the organization will try to quell these fears. The conversation was really interesting so I decided to share it with you in full, sans light editing for clarity and consistency.

The Electro-Magnetic Freakout on the Cape

And more of the week’s news around project development.

The United States.

1. Barnstable County, Massachusetts – I have a whopper of an update on the Vineyard Wind project, which might be in operation but risks becoming fodder in the fight against offshore wind.

  • Like all offshore wind projects, Vineyard Wind has to send power to the coastline via cable. One of the three sites where these giant power lines land is Barnstable, a small shore community, where longtime residents for years have voiced concerns about electromagnetic fields or EMF.
  • Concerns about EMF are comparable to those about infrasound from data centers. We do not know whether these concerns are really rooted in legitimate health impacts, as I have written, but regardless this remains a common concern raised around large high-voltage power lines, including those for offshore wind projects.
  • On June 30, the town’s board of health heard from a group of Barnstable residents who claim to have measured EMF from the town’s wind cable. The same group, Save Greater Downes Beach, had unsuccessfully sought to stop the cables through litigation and public pressure.
  • This board of health meeting was controversial: Ahead of the meeting, the director of Sierra Club’s Massachusetts chapter wrote the board of health requesting their testimony be limited and no action be taken on the findings. “Concerns being raised about electromagnetic field exposure associated with Vineyard Wind 1’s underground export cables are not only invalid but outside of the Board of Health’s jurisdiction,” wrote chapter director Vick Mohanka, according to a copy of the letter posted to Facebook by anti-wind activist Susanne Conley.
  • This Sierra Club chapter was right to be concerned about how this meeting would affect Vineyard Wind. I watched the lengthy testimony before the board of health. Activists presented a case that the town should implore regulators with authority to deeply study the wind farm cables. They asked the board of health to back a state study on EMF and put the question before the Massachusetts permitting regulator, the Energy Facility Siting Board.
  • “We’re not asking the board to place any restrictions or limitations on the project at this time,” Gary Peters, a local medical professional and member of Save Greater Dowses Beach, told the board. “We’re asking you to put that ball in the court of EFSB.”
  • The board was receptive to this request. Board chair F.P. Lee told the group he would “take this under advisement” and said he’d talk to their legal department about it. Daniel Luczkow, the board’s vice chair, said he agreed with activists’ feelings that Barnstable residents were “guinea pigs.”
  • “It sounds like the contention is that these levels we’re measuring are much, much higher than the information given when the project was started,” Luczkow said. “We’re the only place on the planet, maybe, that actually runs these [cables] through a populated area and we have no idea what type of damage they’re causing?”
  • Should Barnstable strenuously take this issue up, I would predict it only be a matter of time before it’s also raised by organs of the federal government. Health and Human Services Secretary Robert F. Kennedy Jr. last year asked the Centers for Disease Control to study negative health impacts from precisely this infrastructure. This kind of hyperlocal squabble is often what manifests as conversation in anti-wind opposition circles, and Vineyard Wind was already causing PR headaches for the energy transition.

2. Prince William County, Virginia – Northern Virginia is officially hostile territory for data center developers, and I learned about it through a call from my mom.
