Houston-based Pyrophyte Acquisition Corp., a “blank check” SPAC, plans to merge with Canadian quartz silica producer Sio Silica Corp. in a deal valued at more than $700 million.

The companies say the deal carries an enterprise value of $708 million and an equity value of $758 million.

Sio is sitting on a potential supply of 15.2 billion metric tons of high-purity quartz silica, a material needed to produce energy transition technologies such as photovoltaics, solar panels, semiconductors, batteries, and other electronics. Proceeds from the merger will be earmarked for construction of the first phase of Sio’s silica extraction and processing facility near Winnipeg, Manitoba.

“We searched long and hard for the right candidate to combine with Pyrophyte and its energy transition mission. Sio fulfilled all our criteria,” Bernard Duroc-Danner, chairman of Pyrophyte, says in a news release. “We are proud to join Sio on its journey to supply what is becoming in many countries around the world one of the most important strategic minerals for the world’s energy transition.”

In 2021, Pyrophyte’s stock began trading on the New York Stock Exchange in an IPO valued at $201.25 million. Since then, it’s solely been a special purpose acquisition company (SPAC) without any business operations. Typically, a SPAC aims to acquire or merge with a private company that boasts a promising business model.

Duroc-Danner is former chairman, president, and CEO of Houston-based oilfield equipment and services company Weatherford International Ltd.

Calgary, Alberta-based Sio says high-purity quartz silica will represent a $30 billion global market opportunity by 2030. Among the products that rely on silica are semiconductors, solar panels, photovoltaic (solar) cells, optical fibers, and batteries.

Once the deal closes, the combined company will operate as Sio Silica Inc., whose stock will be traded on the New York Stock Exchange. Sio’s CEO, Feisal Somji, will lead the newly formed company.

The deal has been approved by Sio’s and Pyrophyte’s boards but still must be endorsed by the companies’ shareholders.

Q&A: Houston robotics entrepreneur on IPO, military innovation, and more

automation nation

Almost a decade ago, Nicolaus Radford founded a robotics company that automated underwater operations for heavy industry customers. Now, the company provides its robotics-as-a-service business to customers across industry, providing key analytics, risk-managed monitoring, and emission-reducing service.

Nauticus Robotics (Nasdaq: KITT) went public via SPAC last year, and Radford, CEO and founder, sat down with InnovationMap earlier this year to share the unique challenges he faced with the IPO, the company's partnerships with the United States Marine Corps, and more. Check out the shortened Q&A below and head to InnovationMap for the full conversation.

InnovationMap: Tell me about life after IPO. What’s been surprising for you leading your company through the transition and now on the other side of IPO?

Nicolaus Radford: I'll tell you what, it’s the hardest thing I ever did in my professional career by a factor of 10. It was a very exceptionally challenging period of time. It took a long to complete the transaction, and the market was just changing under our feet. Rules were and regulations were changing — were we grandfathered in or were we not?

I'm part of some business organizations and, and some of those confidential relationships have turned into friendships. And a couple of them call me and they're like, “we're really worried. We think this is going to be we don't know if you're going to get it done. And we just want you to be aware that you're not you may not get it done.” It is a little scary because once you engage in it, you're running quite a tab with bankers and law firms and all sorts of things. And if you don't complete the deal, it just might kill the company.

But we did it. We were one of a few people last year to actually get a deal over the line. I'm very proud of that. I think it speaks to the quality of the deal that we had. The macro economic environment was exceptionally difficult. It remains to be very difficult today. But we had strong backing from our strategic investors and our partners that were already on the cap table. They put a tremendous amount of money into the deal.

You know, I look back on it and it's, you know, ringing the Nasdaq bell when we listed, and giving that speech at the podium — it was a surreal moment. I remember when I was standing there looking at the Nauticus logo on the seven-story Nasdaq tower, having as many people in the company as we could bring, and just sharing that moment with all of them.

I was excited but cautious at the same time. I mean, the life of a CEO of a public company at large, it's all about the process following a process, the regulations, the administration of the public company, the filings, the reportings — it can feel daunting. I have to rise to the occasion to tackle that in this the next stage of the company.

IM: You’re working with the military on a project that adapts Nauticus tech for Marine Corps use. What’s it been like working with the military on this project?

NR: We've probably worked with military interests for the last six years, but all of the things that we have been doing have been extremely confidential and hush. Now we've been able to work with customers that have a stronger public facing persona, and the Defense Innovation Unit is one of those.

Their charter is it's quite literally looking for commercial technology and adapting that towards military applications, and so it's been nice to be able to show the utility and the application of of a lot of our technology and what we've been working on for so long as it's applied on a broader scale to the big services, whether it's the Navy or the Marine Corps.

Both of the programs we’re working on are all about mine countermeasures, and mines are really, really difficult, especially underwater mines. We've been we've been applying all of Nauticus’s broad technology portfolio to being able to search autonomously and being able to identify and neutralize threats in the water. I love that mission because anytime we can remove our service men and women from these situations, that's just the right thing to do.

IM: What’s next for Nauticus?

NR: What’s next is tough to talk about, because I can only talk about what’s already been published. I see Nauticus being the preeminent ocean robotics company. I want Nauticus to be an empire. It starts small but it grows — and it grows in many different ways, and we’re exploring all of those different ways to grow. We’re leading a technology renaissance in the marine space — and that happens only a few times in an industry.

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.
