money moves

Verde Clean Fuels announced the entry into a stock purchase agreement with Cottonmouth Ventures, a wholly-owned subsidiary of Diamondback Energy.

With the deal, Midland, Texas-based Cottonmouth will make a $50 million equity investment into Houston-based Verde.

The investment will consist of the purchase of 12.5 million shares of Verde’s Class A common stock at a purchase price of $4.00 per share. Closing of the investment is anticipated to occur during the first quarter of the new year, which will be subject to satisfaction of customary closing conditions. The investment would represent the second investment by Cottonmouth in Verde over the past two years, which would equal a total investment of $70 million. This would make Cottonmouth the second largest shareholder of Verde.

“We are pleased to further our relationship with Diamondback and continue advancing our plans to deploy our technology through the development of commercial production plants,” Ernest Miller, CEO of Verde, says in a news release. “Diamondback is a strategic industry partner at the forefront of bringing sustainable operational practices to the oilfield and supporting the overall transition to clean energy.”

Verde Clean Fuels key pioneering technology is its "syngas-to-gasoline plus" (STG+®), which turns diverse feedstocks like biomass, municipal solid waste (MSW), and natural gas – into gasoline or methanol. Verde is able to deploy facilities in areas with abundant and low-cost feedstock. The company has developed two different pathways to gasoline production with the goal of reducing carbon emissions.

Proceeds from the investment are expected to be used to further the development and construction of potential “natural gas-to-gasoline production plants in the Permian Basin and for other general corporate purposes,” according to Verde Clean Fuels. The proposed plants developed by the parties would produce fully-refined gasoline utilizing Verde’s patented STG+® process from associated natural gas feedstock supplied from Diamondback's operations in the Permian Basin. Verde will also expand its board of directors to eight members and appoint a new director to be designated by Cottonmouth. Cottonmouth will be entitled to appoint an observer to the company’s board.

“This investment is an expression of confidence in our technology, which we believe has the potential to alleviate economic and environmental concerns in the Permian Basin and other pipeline-constrained basins, where flaring and stranded natural gas represent a significant challenge,” Miller adds in the release.

Investor on Texas as a climatetech hub, disruption opportunities with the grid, and more

Q&A

One of the biggest challenges to the energy transition is finding the funds to fuel it. Tyler Lancaster, partner at Energize Capital, is playing a role in that.

Energize Capital, based in Chicago, is focused on disruptive software technology key to decarbonization. One of the firm's portfolio companies is Amperon, which raised $20 million last fall.

In an interview with EnergyCapital, Lancaster shares what he's focused on and why Amperon caught Energize Capital's attention.

EnergyCapital: Energize Capital has been investing in climate tech for the better part of a decade now. What types of companies are you looking for and how are these companies’ technologies affecting the greater energy transition?

Tyler Lancaster: We partner with best-in-class innovators to accelerate the sustainability transition. This means identifying climate technology companies at various stages of maturity — from early commercialization to approaching the public markets — that we can help scale and realize their full potential. We invest in software-first climate technology businesses, with a focus on asset-light digital solutions that can help scale sustainable innovation and enable the new energy economy. Our portfolio currently drives software applications across renewable energy, industrial operations, electrification & mobility, infrastructure resilience, and decarbonization. We primarily focus on proven, commercially available and economically viable energy transition solutions (solar, wind, batteries, heat pumps, etc.). These solutions suffer from challenges related to efficient deployment or operations, where enabling digital platforms can play a key role in optimizing costs.

EC: Amperon is one of Energize Capital's portfolio companies. What made the company a great investment opportunity for Energize Capital?

TL: Accelerating the energy transition will require critical forecasting tools like what Amperon provides. This is underscored by the escalating impact of extreme weather events, increasing penetration of variable energy resources, like wind and solar, on the supply side, and surging demand growth driven by flexible loads and rapid electrification. We believe the need for Amperon’s platform will only continue to grow, and their increased raise from Series A to Series B showed they are scaling smartly. We’ve also known Sean Kelly, Abe Stanway, and the entire Amperon team for a long time, and building strong relationships with founders is how we like to do business. Amperon has built a blue-chip customer base in the energy sector in a very capital efficient manner, which is more important than ever for startups operating in the current equity market environment.

EC: One of the energy transition’s biggest problems is sourcing and storing reliable and affordable energy. What have you observed are the biggest problems with Texas’ electricity grid and what types of new tech can help improve these issues?

TL: Today’s electricity grid and the demands we’re putting on it look very different than they ever have. Major changes in climate and extreme weather show how perilous and unreliable the power grids in this country are, particularly in regions like Texas that don’t have the right infrastructure to shield grids from unusual temperatures — just look at the damage done by 2021’s historic Winter Storm Uri. And consumer demand for electricity is increasing as electrification accelerates globally. The makeup of the grid itself is shifting from centralized power plants to distributed clean energy assets like solar arrays and wind turbines, which brings issues of intermittent electricity production and no traditional way to forecast that.

Tech solutions like Amperon are the only way to navigate the nuances of the energy transition. With global net-zero goals and impending Scope II accounting, Amperon’s expertise in granular data management further enables companies to build accurate, dynamic forecasting models with smart meter data and get more visibility into anticipated market shifts so they can optimize their energy use — all of which helps to create a more resilient and reliable power grid.

EC: You are also on the board of the company, which recently announced a collaboration with Microsoft’s tech. What doors does this open for Amperon?

TL: Partnering with Microsoft and offering its energy demand forecasting solution on the Azure platform enables Amperon to better serve more companies that are navigating the energy transition and a rapidly evolving grid. Many power sector companies are also undergoing cloud migrations with Microsoft Azure having high market share. This partnership will specifically accelerate Amperon’s reach with utility customers, who typically have slower sales cycles but can greatly benefit from improved accuracy in energy demand forecasting and adoption of AI technologies.

EC: As a non-Texas investor, how do you see Houston and Texas-based companies’ investability? Has it changed over the years?

TL: While most tech startups are concentrated on the coasts and in Europe, we see Texas emerging as a hub for energy and climate focused startups due to its vicinity to energy giants, which represent potential customers. Texas leads the country in renewable energy production and sits at the forefront of the transition. Energy companies based in this region are relying on technology innovation and software tools to modernize operations and meet the evolving demands of their customers.

Houston investor launches energy transition venture studio to help elevate early-stage hardtech startups

money moves

The way Doug Lee looks at it, there are two areas within the energy transition attracting capital. With his new venture studio, he hopes to target an often overlooked area that's critical for driving forward net-zero goals.

Lee describes investment activity taking place in the digital and software world — early stage technology that's looking to make the industry smarter. But, on the other end of the spectrum, investment activity can be found on massive infrastructure projects.

While both areas need funding, Lee has started his new venture studio, Flathead Forge, to target early-stage hardtech technologies.

“We are really getting at the early stage companies that are trying to develop technologies at the intersection of legacy industries that we believe can become more sustainable and the energy transition — where we are going. It’s not an ‘if’ or ‘or’ — we believe these things intersect,” he tells EnergyCapital.

Specifically, Lee's expertise is within the water and industrial gas space. For around 15 years, he's made investments in this area, which he describes as crucial to the energy transition.

“Almost every energy transition technology that you can point to has some critical dependency on water or gas,” he says. “We believe that if we don’t solve for those things, the other projects won’t survive.”

Lee, and his brother, Dave, are evolving their family office to adopt a venture studio model. They also sold off Azoto Energy, a Canadian oilfield nitrogen cryogenic services business, in December.

“We ourselves are going through a transition like our energy is going through a transition,” he says. “We are transitioning into a single family office into a venture studio. By doing so, we want to focus all of our access and resources into this focus.”

At this point, Flathead Forge has seven portfolio companies and around 15 corporations they are working with to identify their needs and potential opportunities. Lee says he's gearing up to secure a $100 million fund.

Flathead also has 40 advisers and mentors, which Lee calls sherpas — a nod to the Flathead Valley region in Montana, which inspired the firm's name.

“We’re going to help you carry up, we’re going to tie ourselves to the same rope as you, and if you fall off the mountain, we’re falling off with you,” Lee says of his hands-on approach, which he says sets Flathead apart from other studios.

Another thing that's differentiating Flathead Forge from its competition — it's dedication to giving back.

“We’ve set aside a quarter of our carried interest for scholarships and grants,” Lee says.

The funds will go to scholarships for future engineers interested in the energy transition, as well as grants for researchers studying high-potential technologies.

“We’re putting our own money where our mouth is,” Lee says of his thesis for Flathead Forge.

Houston cleantech co. secures investment from Mitsubishi

money moves

A Houston-based company that's created a photocatalytic reactor that uses light instead of heat to cleanly manufacture chemicals has announced its latest investor.

Syzygy Plasmonics announced a strategic investment agreement with Mitsubishi Heavy Industries Ltd., executed through Mitsubishi Heavy Industries America Inc. The terms of the deal were not disclosed, but Syzygy reports that the funding will go toward commercialization and development of its products.

"MHIA has been making moves to establish themselves as one of the leaders in the energy transition," Syzygy CEO Trevor Best says in a news release. "Formalizing our relationship with them shows their commitment to helping scale cutting edge technology and opens up new avenues for Syzygy and MHIA to work together as we commercialize our industrial decarbonization platform."

Currently, Rigel, the commercial-scale photoreactor, is being tested in Syzygy's Pearland facility. Founded based off a breakthrough discovery out of Rice University from co-founders and professors Naomi Halas and Peter Nordlander, Syzygy closed a $76 million series C financing round last year, a $23 million series B round in 2021, and its $5.8 series A in 2019.

The funding will support advancement and commercialization of the technology and is a part of Mitsubishi Heavy Industries Group's commitment to decarbonization.

"By collaborating with and investing in partners with innovative technologies, MHI Group is working to build a hydrogen ecosystem and a CO2 ecosystem that can contribute to the realization of a decarbonized society," the company writes in a statement. "Through this investment, Mitsubishi Heavy Industries will support Syzygy's efforts to develop innovative alternative technologies that will lead to the diversification of both ecosystems."

The Supreme Court heard arguments in a fight over plans to store nuclear waste at sites in rural Texas and New Mexico. President Joe Biden's administration and a private company with a license for the Texas facility appealed a ruling by the 5th U.S. Circuit Court of Appeals that found that the Nuclear Regulatory Commission exceeded its authority in granting the license. The outcome of the case will affect plans for a similar facility in New Mexico roughly 40 miles away.

On this issue, President Donald Trump's administration is sticking with the views of its predecessor, even with Texas Gov. Greg Abbott, a Republican ally of Trump, on the other side.

The push for temporary storage sites is part of the complicated politics of the nation’s so far futile quest for a permanent underground storage facility. Continue reading.

Energy tech company Baker Hughes announced two major clean energy initiatives this month.

The Houston-based company has teamed up with Dallas-based Frontier Infrastructure to develop carbon capture and storage (CCS), power generation and data center operations in the U.S.

Baker Hughes will supply technology for Frontier’s nearly 100,000-acre CCS hub in Wyoming, which will provide open-access CO2 storage for manufacturers and ethanol producers, as well as future Frontier projects. Frontier has already begun drilling activities at the Wyoming site.

“Baker Hughes is committed to delivering innovative solutions that support increasing energy demand, in part driven by the rapid adoption of AI, while ensuring we continue to enable the decarbonization of the industry,” says Lorenzo Simonelli, chairman and CEO of Baker Hughes.

Additionally, Baker Hughes announced this week that it was selected by the U.S. Air Force and the Department of Defense’s Chief Digital and Artificial Intelligence Office (CDAO) to develop utility-scale geothermal power plants that would power global U.S. military bases.

Baker Hughes was granted an "awardable," or eligible, status through the CDAO's Tradewinds Solutions Marketplace, which aims to accelerate "mission-critical technologies," including AI, machine learning and resilient energy technologies. The potential geothermal plants would provide cost-effective electricity, even during a grid outage.

“The ability of geothermal to provide reliable, secure baseload power makes it an ideal addition to America’s energy mix,” Ajit Menon, vice president of geothermal, oilfield services and equipment at Baker Hughes, said in a news release. “Baker Hughes has been a pioneer in this field for more than 40 years and our unique subsurface-to-surface expertise and advanced technology across the geothermal value chain will help the U.S. military unlock this critical domestic energy source, while simultaneously driving economic growth and energy independence.”
