Evove Raised $13M. Its DLE Rivals Raised 25x That. Kurita Picked Evove.

Full disclosure before I answer it: I’ve been kicking the tires on Evove for years, since my own LeckerLithium experiments and an earlier conversation with the company, and I bumped into Andrew Walker, their CCO, in Amsterdam, where he invited me up to Newcastle to see the pilot for myself. So I went and stood in the field. But the reason I think this is worth an article rather than just an episode is what the numbers around Evove say once you line them up against everyone else chasing the same prize, which is a view you only get if you’ve been tracking the whole field.

Who’s actually winning the money race in lithium-from-water?

Almost nobody you’d expect. When I sort my direct-lithium-extraction list by capital raised, the top of the table is a wall of American cheques: Lilac Solutions at over $318 million, Energy Exploration Technologies (you’ll know them as EnergyX) at $134 million, then Canada’s Summit Nanotech near $90 million and Mangrove at $85 million. Evove sits a long way down that column at $12.95 million across five rounds since 2018, which puts a British company with one of the most-watched DLE pilots in the world eleventh on my list by money raised.

Two things jump out of that table once you sit with it. The first is a quiet naming pattern: a striking number of these companies started life as water businesses and rebranded toward the shinier word. Mangrove Water Technologies became Mangrove Lithium. Evove itself used to be G2O Water Technologies. The water people worked out, before the market did, that brine treatment and lithium extraction are close to the same job. The second is that Britain has quietly grown a whole DLE cluster, because alongside Evove my list carries Seloxium, CleanTech Lithium, WaterCycle Technologies and Salinity Solutions, none of them household names, all working the same seam (I’ve profiled one of them, how Salinity Solutions halves the energy of squeezing water out of any stream).

So why did the smallest serious player win Kurita?

Because Evove made a different bet with its money, and the bet is the story. Look again at the companies above it on the funding table and you’ll notice most of them did the same thing with the cash: they bought a lithium asset, a deposit or a site of their own, so they’d have somewhere to prove the technology and, eventually, a resource to sell (it’s how Standard Lithium and Adionics have played it). Walker is blunt that Evove deliberately refused to play it that way.

Buying a deposit is what turns a $13 million company into a $300 million one, because resources are expensive and slow. Evove stayed a technology licensor instead, selling its membranes and coatings and even its 3D-printing know-how to whoever is building the plant, and partnering with an asset owner (Northern Lithium) rather than becoming one. That’s the difference between a mining mindset and a water one, and it’s the whole reason a small balance sheet could get this far.

I’ll admit this is catnip for me, because I’ve been arguing a version of it across my whole lithium series, from the evaporation ponds of Salta to the DLE startups you trip over walking through Vancouver: strip away the mystique and direct lithium extraction is a water-treatment plant that happens to output something worth $15,000 a tonne, which is the whole case I’ve made for water technology in lithium.

Does the technology actually deliver?

This is where the muddy field earns its place, because an asset-light story collapses the moment the technology underperforms on someone else’s site. Between January and April 2025, Evove ran a 1:15-scale demonstration plant with Northern Lithium at Ludwell Farm in County Durham, on real brine pumped from under the North Pennines, and the published results held up: up to 92% end-to-end lithium recovery, an intermediate at 96.5% purity, and calcium and magnesium pushed below the 5-parts-per-million line where the instruments stop finding them (Evove, “DELiVERED,” October 2025).

The 96.5% is the number that matters, and here’s why, because it’s easy to skate past a purity figure. Walker reckons the intermediate most DLE outfits publish lands around 80 to 82% pure. Evove came out of this pilot at 96.5%, and that gap is money rather than bragging, because the closer your intermediate starts to battery grade, the less you spend dragging it the rest of the way. One of Evove’s conversion partners put real figures on it: starting from the cleaner Evove stream cut their downstream conversion cost by roughly 25% on capex and 22% on opex.

How it gets there is the divalent removal up front, stripping the calcium and magnesium out with its nanofiltration membranes before the lithium ever goes for polishing, and that same cleanliness is what lets Evove recycle its water and regenerate its own acids and bases on site, the basis of its zero-water and zero-chemical-footprint claims. One number you may have seen needs a quick correction, though: the 99.1% that’s been attached to this story is the selectivity of Evove’s Separonics membrane on a hexadecane rejection test, not a lithium-purity figure. The membrane is extraordinarily selective, the lithium results are the 92% and the 96.5%, and conflating the two is exactly the kind of thing that makes an investor distrust the rest of your deck. I’d add my usual asterisk to “zero footprint” too, since it’s always more site-specific than a pitch slide admits, but as DLE goes this is the cleanest version I’ve looked at.

What did Kurita actually buy?

Not a stake, a chokehold. In October 2025 Kurita Water Industries completed an investment that made it Evove’s largest shareholder and, more tellingly, handed it exclusive global rights to use Evove’s DLE technology (Kurita Water Industries, October 2025). In the same announcement, Northern Lithium, Kurita and Evove committed to a three-way plan for commercial UK lithium starting end of 2027, at 500 tonnes a year and ramping past 20,000 tonnes a year by 2035 (PRNewswire, October 2025). So the modular plants get built and manufactured by one of the largest water-treatment companies on earth, while Evove keeps being the technology inside them. For an asset-light licensor, that’s the dream customer, and it’s not the only Japanese name circling: Walker also described an offtake-and-project-finance tie with a trading house he could only call a $100-billion-turnover company.

What I’d flag for an investor is the pattern, not the single deal. The serious money entering DLE from the water side is strategic, not venture, with Kurita buying into Evove and Veolia already running DLE membranes at Centenario in Argentina. The water majors have decided lithium is their adjacency, and they’re shopping for the technology rather than building it, which is precisely the exit a company like Evove is built to be.

What could still go wrong?

Plenty, and I’d be selling you the pitch deck if I skipped it. Asset-light cuts both ways: leaning on Northern Lithium and Kurita gets Evove to scale cheaply, but Evove no longer fully controls its own destiny, and Walker himself calls the partner route “a lot more risky.” Manufacturing is the other open question, because he’s refreshingly candid that churning out these 3D-printed ceramic modules at volume is still unproven, and he’s watched additive manufacturing over-promise before. And the capital math hasn’t gone away just because Kurita showed up: water-tech venture money is thin, hardware is unforgiving, and one large strategic backer is not the same as a deep market of investors. Hold the 92% and the 96.5% in one hand and those three in the other.

Why this matters now

Because the supply chain is the whole game. China spent two decades building a near-monopoly on lithium-processing technology and in 2025 began enforcing export curbs on exactly that know-how, which is what turns a working extraction line in a Durham field from a science fair into a strategic asset. Evove’s answer to the obvious objection, that a scattered Western industry can’t catch up, is counter-intuitive and the reason I keep thinking about it.

Three years from now, if Northern Lithium’s commercial plant comes online as planned, it won’t look like a mine. It’ll look like a water-treatment facility that happens to produce one of the most valuable materials on earth, which is either a quietly radical idea or the most obvious one going, depending on whether you came up through mining or through water. You can probably guess which side of that field I was standing on.

The full conversation with Andrew Walker, plus the walk around the Northern Lithium site, is in the episode embedded above. And I dug into the wider water-meets-lithium thesis across my newsletter, if you want the map the rest of this sits on.

Frequently asked questions

What is direct lithium extraction (DLE)?

A family of processes that pull lithium straight out of brine with membranes, sorbents or ion exchange, instead of evaporating brine in ponds for months or mining hard rock. It’s faster and uses far less land and water, which is why the water-treatment industry has moved into it.

What is Evove?

A UK company, formerly G2O Water Technologies, that makes graphene-oxide-coated reverse-osmosis and nanofiltration membranes plus 3D-printed membrane spacers, and applies them to direct lithium extraction and industrial water treatment. Its advanced filtration line is branded Separonics, commercial launch planned for 2026.

What did Evove’s Northern Lithium pilot achieve?

At the County Durham demonstration in early 2025: up to 92% end-to-end lithium recovery, 96.5% purity for the intermediate lithium chloride and sulfate, divalent ions (calcium, magnesium) below 5 parts per million, across more than 300 hours and 78 million data points.

How much has Evove raised, and who backs it?

About $12.95 million across five rounds since 2018, including a $6.9 million Series A in 2023 led by At One Ventures. In October 2025 Kurita Water Industries became its largest shareholder and took exclusive global rights to its DLE technology.

How does Evove compare to other DLE companies?

By capital raised it’s far smaller than leaders like Lilac Solutions (over $300M) or EnergyX (over $130M); it sits about eleventh on my list of forty. Its differentiator is the asset-light model: it licenses technology and partners with asset owners rather than buying lithium deposits of its own.

Is Evove’s lithium battery-grade?

The pilot produced a high-purity 96.5% intermediate; battery-grade lithium carbonate needs 99.5% or above, reached in a downstream conversion step. Evove has separately made around 2 kg of battery-grade lithium carbonate above 99.5% purity at its own test centre.

Who is Andrew Walker?

Evove’s CCO, or Chief Commercial Officer. He came into water from additive manufacturing, which is where the company’s 3D-printing expertise originates.
