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.

Will Blue States Open Up Their Wallets for Renewables?

A conversation with Heather O’Neill of Advanced Energy United.

The Fight Q&A subject.

This week’s conversation is with Heather O’Neill, CEO of renewables advocacy group Advanced Energy United. I wanted to chat with O’Neill in light of the recent effective repeal of the Inflation Reduction Act’s clean electricity tax credits and the action at the Interior Department clamping down on development. I’m quite glad she was game to talk hot topics, including the future of wind energy and whether we’ll see blue states step into the vacuum left by the federal government.

The following conversation has been lightly edited for clarity.

The Anti-Renewables Movement is Coming for Your Wires

The Grain Belt Express was just the beginning.

The anti-renewables movement is now coming for transmission lines as the Trump administration signals a willingness to cut off support for wires that connect to renewable energy sources.

Last week, Trump’s Energy Department with a brief letter rescinded a nearly $5 billion loan guarantee to Invenergy for the Grain Belt Express line that would, if completed, connect wind projects in Kansas to areas of Illinois and Indiana. This decision followed a groundswell of public opposition over concerns about land use and agricultural impacts – factors that ring familiar to readers of The Fight – which culminated in Republican Senator Josh Hawley reportedly asking Donald Trump in a meeting to order the loan’s cancellation. It’s unclear whether questions around the legality of this loan cancellation will be resolved in the courts, meaning Invenergy may just try to trudge ahead and not pick a fight with the Trump administration.

Vineyard Wind Is Besieged Again

And more of the week’s most important conflicts around renewable energy.

The United States.

1. Nantucket County, Massachusetts – The fight over Vineyard Wind is back with a vengeance. But can an aggrieved vacation town team up with conservative legal activists to take down an operating offshore wind project?

  • The offshore wind project, which is under construction and currently provides power to Massachusetts, was threatened this week when Nantucket signaled it may sue Vineyard Wind over a laundry list of demands related to the facility and last year’s blade breakage. Then less than 24 hours later, the Texas Public Policy Foundation – a conservative legal advocacy group – filed a petition to the Interior Department requesting it not only reconsider previous permits issued for Vineyard Wind but also halt operations at the site.
  • It’s hard to ignore the timing here: before this flurry of activity, the Interior Department released a new secretarial order that laid out many ways it would potentially go after wind facilities. One method would be potentially settling lawsuits filed against both offshore and onshore wind projects in favor of plaintiffs.
  • We are still waiting to see if Interior will take up the Vineyard Wind petition. But this activity suggests that opponents of offshore wind feel increasingly emboldened by the anti-renewables direction that Trump has taken in recent weeks, and we may soon find out if their aspirations for killing operating projects are well-founded.

2. Henry County, Virginia – A fresh fiasco around a solar farm is renewing animus against solar projects in the Commonwealth of Virginia.
