GOOD AS GOLD

Cleantech startup Gold H2, a spinout of Houston-based energy biotech company Cemvita, has named oil and gas industry veteran Prabhdeep Singh Sekhon as its CEO.

Sekhon previously held roles at companies such as NextEra Energy Resources and Hess. Most recently, he was a leader on NextEra’s strategy and business development team.

Gold H2 uses microbes to convert oil and gas in old, uneconomical wells into clean hydrogen. The approach to generating clean hydrogen is part of a multibillion-dollar market.

Gold H2 spun out of Cemvita last year with Moji Karimi, co-founder of Cemvita, leading the transition. Gold H2 spun out after successfully piloting its microbial hydrogen technology, producing hydrogen below 80 cents per kilogram.

The Gold H2 venture had been a business unit within Cemvita.

“I was drawn to Gold H2 because of its innovative mission to support the U.S. economy in this historical energy transition,” Sekhon says in a news release. “Over the last few years, my team [at NextEra] was heavily focused on the commercialization of clean hydrogen. When I came across Gold H2, it was clear that it was superior to each of its counterparts in both cost and [carbon intensity].”

Gold H2 explains that oil and gas companies have wrestled for decades with what to do with exhausted oil fields. With Gold H2’s first-of-its-kind biotechnology, these companies can find productive uses for oil wells by producing clean hydrogen at a low cost, the startup says.

“There is so much opportunity ahead of Gold H2 as the first company to use microbes in the subsurface to create a clean energy source,” Sekhon says. “Driving this dynamic industry change to empower clean hydrogen fuel production will be extremely rewarding.”

3 takeaways from COP28 from Houston biotech, sustainability founder

big picture

Before he even had a chance to recover from the jetlag, Moji Karimi was thinking about his biggest takeaways from 2023 United Nations Climate Change Conference or Conference of the Parties, more commonly known as COP28.

Karimi, CEO and co-founder of Cemvita, a biotech company with sustainable solutions for the energy transition, joined the Houston Innovators Podcast this week to discuss what his biggest takeaways were.

"It was a pretty amazing experience," Karimi says, comparing the event to how CERAWeek has evolved to really have a strong presence in its innovation-focused track called Agora. "This year you had a massive section for innovation and sustainability. I think that will become a theme in COP29 and beyond to bring entrepreneurs, investors, and more participating in the event."

Karimi's three big observations are outlined below, as is the full podcast with him sharing more about Cemvita's growth this year.


Expanding the environmental footprint

One of the big things Karimi observed was that there seems to be a rising conversation about not only how carbon emissions are effecting climate change, but that companies and countries need to look more broadly at their environmental impacts.

Specifically, Karimi learned about the new framework Task Force on Nature-Related Financial Disclosures (TNFD), an addition to Task Force on Climate-Related Financial Disclosures (TCFD), which was introduced a few years back.

"TNFD is the new framework to capture non-carbon emissions-related aspects of an impact on the environment, such as biodiversity loss," he says.

Language has evolved to reflect this shift too, Karimi says, referencing "nature-positive tech" and "nature tech." He says he feels like Europe has led the way so far, but in the next year or two the conversations will come to the United States.

"Some of this is driven by COP30 being in Brazil and being focused on biodiversity," he adds.

A major focus on nuclear

Karimi says he saw a lot of support for nuclear energy, which can lower the cost and carbon intensity of power. Personally, Karimi is wondering what happens if and win nuclear is better adapted, solving the current challenges the power industries face.

"What I'm interested in is so many other climate tech applications that are enabled once you have low-cost, and low-carbon power from nuclear energy. That will be interesting to watch," he says.

Actionism, not activism

Lastly, Karimi says he saw a huge push toward action, not simply advocacy. The emphasis on "actionism" included activations for COP28 attendees to share what actions could be taken now.

"The point was to all come together, no matter where you come from, and focus on what actions you can take," he says. "It was interesting to bring people together in a different way. We'll see how that translates into actions from here on."

Research from Rice University that merges biology with electrochemistry has uncovered new findings on how some bacteria generate electricity. Research showed how some bacteria use compounds called naphthoquinones, rather than oxygen, to transfer electrons to external surfaces in a process known as extracellular respiration. In other words, the bacteria are exhale electricity as they breathe. This process has been observed by scientists for years, but the Rice team's deeper understanding of its mechanism is a major breakthrough, with implications for the clean energy and industrial biotechnology sectors, according to the university.
