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.

How Building Transmission Could Lower Electricity Costs

Talking with National Grid’s Matthew Satterwhite about his new report with S&P Global.

The Q&A subject.

This week’s conversation is with Matthew Satterwhite, head of U.S. policy for National Grid. This week National Grid released a report in collaboration with S&P Global I found noteworthy amidst the data center backlash, asserting that building new transmission lines can potentially reduce consumer costs. I reached out asking if we could chat about how this argument leans into the fight over hyperscale infrastructure. I found our conversation illuminating and educational.

The following Q&A was lightly edited for clarity.

The Solar Farm-to-Data Center Switcheroo Hits a Snag

Plus more of the week’s biggest development fights.

1. Clark County, Nevada – The first data center approved on federal lands has hit a legal brick wall.

  • On Monday, the Townsite 2 solar farm-to-data center environmental review swap I’ve previously covered received a stay from the Interior Department’s board of appeals. David Gunter, a Biden appointee, ruled that the Center for Biological Diversity’s appeal of the permit flip was likely to succeed on the merits because a solar farm … is not a data center. Seems logical!
  • As I covered at the time, the Bureau of Land Management approved the environmental review swap claiming that a solar farm and a data center have essentially the same characteristics. It was a bold claim. Both the agency and Townsite said the characteristics would have substantially the same environmental impacts. Gunter shrugged off the claim idea, however, stating that statute requires projects to be both substantially similar and have equally similar impacts under the National Environmental Policy Act.
  • Crucially, Gunter also noted that the federal agency had never done an environmental review of any data centers under NEPA, so there’s not even a proper frame of reference. “BLM has not studied the Townsite data center project, or indeed any other data center project, in any environmental document,” he wrote.

2. Jackson County, Missouri – We have yet another high-profile case of a city councilor losing their job over voting for a data center, and this one’s a doozy.

These 5 States Are Primed for a Data Center Pause

Where temporary moratoria could happen next.

Brace yourself for more statewide data center moratoria.

So far there are only two full state-wide blocks on data center permits, in New York and Texas. At least fifteen states have moratorium legislation in the pipeline, but few if any of those bills stand a chance of becoming law in the short term. Here are five states, however, where a broad development pause may gain momentum in the next year or two — and all of them are crucial to watch this November.
