I invested in CPH2 in 2022 and it went down like 90%, however I continued to follow the companies progress and found the progress in their press releases encouraging: basically, a lot of companies are interested in buying their product, or getting a licence to manufacture and sell their product. So I decided to buy a load at the rock bottom prices (5p, whereas my original investment was 61p) and I thought I'd mention CPH2 here because based on recent price activity, there might be something here.

I just kept seeing CPH2 as the top daily mover in my portfolio, often seeing +20% and at that huge run up my position actually went green (which after seeing -90% never thought would happen) now that it's had a huge drop back I thought I'd mention it here if anyone is interested.

They've been putting out some good press releases past few months, multiple MoUs even one with Siemens.

So about the company:

CPH2 has developed a 'membrane free electrolyser' that means they can split water into hydrogen and oxygen without a membrane which constantly decays and can require expensive materials such as platinum.

Now why would you want hydrogen when hydrogen cars are a flop? Actually, their first customer bought the unit for the pure oxygen (for aerobic digestion of sewage) and the pure hydrogen is a valuable by-product.

What we need in the UK, especially in Scotland where too much wind power is produced, is a load of these CPH2 units, using all the excess electricity to generate hydrogen that we could then store, so when the wind isn't blowing, burn the hydrogen in gas power plants.

Additionally hydrogen is also used in fertiliser production, oil refining, production of certain chemicals, steel-making and other industrial processes that require high heat, there are some use cases in heavy transportation, synthetic fuels, etc.

Then the pure oxygen is useful in hospitals, wastewater treatment, steelmaking and other industrial processes that require high heat, certain welders, glass making, certain chemicals, fish farming, fermentation, aerospace, mining, ozone generation, etc

So as you can see, there is a load of reasons why the world will want to buy CPH2 units, which have gone through all the tests such as the site acceptance test.

First Deployment of Mobile System Validates New Revenue Channel for Company's Waste Destruction Services Platform

"The Company estimates that a single mobile AirSCWO system has the potential to generate between $500,000 and $1.5 million in annual revenue"

At 5pm UK time, Jim Mellon will be live on r/iAmA to answer questions about Agronomics which invests in cultivated meat and precision fermentation, both of which are set to revolutionize the meat, dairy, egg, palm oil (and some other things that can be produced through precision fermentation such as cocoa) industries with a more sustainable, healthier, ethical and less price volatile alternatives.

1,440,000 shares sold at $2.48. 1,771,263 remaining. Only owns 10.6% of SCWO now.

Must have been an off market exchange as no volume spike showing up on Nasdaq.

Good news I say, because it means he can't abuse his voting rights like he did when he forced board changes. 10% is still a lot, but a lot less influential than when it was about 20%.

Edit: Wasn't actually a sale but a gift:

SEC transaction code G means “bona fide gift.” That is the SEC’s official definition for Form 4 ownership transaction codes.

So this was not reported as an open-market sale and not reported as a purchase. It means Nagar gave away 1,440,000 shares as a gift, rather than selling them for cash in the market.

Third-Party Test Results Presented by ARCADIS Confirm Greater Than 99.9% Destruction and Removal Efficiency for Concentrated PFAS Wastes

MORRISVILLE, NC / ACCESS Newswire / April 30, 2026 / 374Water Inc. (NASDAQ:SCWO) ("374Water" or the "Company"), a leading cleantech and environmental services company, today announced the public release of U.S. government PFAS destruction test results using AirSCWO^(™). The results come from 374Water's participation in an official project led by the US government's Defense Innovation Unit ("DIU") and the Environmental Security Technology Certification Program ("ESTCP").

AirSCWO Destroys PFAS - Permanently

Unlike conventional treatment approaches that filter or concentrate PFAS, AirSCWO permanently destroys organic contaminants. Results were evaluated by a third party and presented by Arcadis, a global leader in environmental engineering, which served as the Company's independent project partner.

"Performing technical demonstrations at scale, such as this DIU project, are essential to build trust within government agencies," said Howard Teicher, the Company's VP, Government. "Watching AirSCWO PFAS-contaminated waste streams, in some cases to a NON-DETECT or single-parts per trillion level, affirms that this technology is ready for operational use."

AirSCWO was evaluated with six distinct PFAS-contaminated waste streams and met or exceeded every key performance objective. Results were evaluated by a third party and presented by Arcadis, a global leader in environmental engineering, which served as the Company's independent project partner. These wastes are the types of concentrated, hard-to-treat waste streams generated at military bases, industrial facilities, and municipal water systems nationwide. The independently validated results demonstrate that AirSCWO achieved greater than 99.9% destruction and removal efficiency ("DRE") across all four highly concentrated PFAS liquid waste streams, and greater than 90% DRE for solid waste streams:

• Allonnia SAFF40 Foam Fractionate - Total PFAS DRE of 99.9998%, with effluent concentrations at or below method detection limits across all primary analytes
• Cyclopure DEXSORB Media Regenerant Still Bottoms - Aggregate PFAS DRE of 99.95%, exceeding 99.99% for PFOS, PFOA, PFHxS, and 6:2 FTS
• ECT2 SORBIX RePURE IX Regenerant Still Bottoms - Aggregate PFAS DRE of 99.996%
• AFFF (Aqueous Film Forming Foam; C8 & C6 Blend) - Aggregate PFAS DRE of 99.997%, exceeding 99.999% for PFOS, PFOA, and 6:2 FTS
• Spent AIX/GAC Mixture - Over 97.5% aggregate PFAS DRE, exceeding 99.5% for PFOS and PFOA
• Spent GAC - Aggregate PFAS DRE greater than 90%, exceeding 99.9% for PFOS and PFOA

All testing followed EPA Method 1633 for liquid-phase PFAS analysis, with supplemental air emissions monitoring conducted via multiple validated federal methods. Critically, hydrogen fluoride stack emissions were non-detectable across all six tests - confirming that AirSCWO fully mineralizes these highly recalcitrant fluorinated organic compounds with no hazardous air emissions.

"These results represent a defining moment for AirSCWO and for the PFAS destruction market as a whole," said Dr. Raj Melkote, Chief Technology Officer for 374Water Inc. "What Arcadis and Clean Earth helped us demonstrate is not just that AirSCWO works - it's that it works across the hardest waste streams, under the most rigorous federal protocols, with third-party analytical data that leaves no room for ambiguity. That we can reduce 75,000,000 nanograms per liter of PFOS in firefighting foam down to less than 120 parts per trillion (less than the reporting limit) is not a theoretical laboratory result. It represents full-scale performance, independently verified, with real-world scenarios and at the exact conditions the market demands. We expect to see the industry respond strongly to this data."

A Large and Growing Market Opportunity

The PFAS problem spans virtually every segment of the water and waste management industry from military installations remediating impacted soil and groundwater, to municipal utilities facing costly biosolids disposal constraints, to landfill operators handling billions of gallons of PFAS-laden leachate each year. Regulatory pressure to move beyond conventional approaches toward permanent destruction solutions is accelerating rapidly, driven by tightening federal and state discharge limits, liability uncertainty and public health concerns.

Importantly, conventional technologies don't destroy PFAS - they concentrate it, creating a residual waste problem that still needs to be solved. AirSCWO is the final step in that treatment chain: receiving the concentrated PFAS residuals that other technologies produce and permanently destroying them and thus eliminating all long-term risks associated with these wastes.

The full results were publicly presented at the Northeast Waste Management Officials Association ("NEWMOA") Science of PFAS Conference on April 16, 2026, by Baxter Miatke, PE, PFAS Treatment Technology Lead at Arcadis, and Lauren March, PE, PFAS Destruction Subject Matter Expert at Arcadis.

374Water will be sharing these results and discussing SCWO applications at its upcoming conference appearances.
