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.

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.
