Houston Energy and Climate Week was full of fast-paced pitches and inspiring technology, showcased during some of the week's signature events.

EnergyTech Cypher's annual Piloathon and Startup Showcase was one of the places to be, bringing together 16 pilot-ready startups to present their best seven-minute pitches before investors, plus 52 companies that demonstrated their technologies on the showcase floor.

"This year's cohort raised the bar," Nada Ahmed, co-founder of EnergyTech Cypher, shared in a news release. "Working with these founders through the pitch preparation process, we saw firsthand the depth of technology and commercial readiness they brought to the stage. Three ties in four categories says it all."

Seven startups took home top honors in various categories, all under this year's theme of "The NEW Energy Industrial Revolution," with three categories ending in a tie. Judges included leaders from Baker Tilly, NRG Energy, Shell, Aramco Ventures, Baker Hughes, Avatar Innovations, Kanin Energy, NoviDigiTech, aiCTO Services, and the FIFA World Cup Houston Committee.

Here's who won in their respective categories:

Future of Industrial Work: Houston-based BigMachine AI, an AI engineer for industrial projects, and Oslo, Norway-based OTee, an automation machinery manufacturer. Otee was also named one of the 10 most-promising startups at the Rice Alliance Energy Tech Venture Forum during HECW.

Industrial Decarbonization: Berkeley-based Oleo, which is developing a biomanufacturing platform to transform biomass waste into carbon-negative, cost-competitive oil feedstocks for advanced fuels

Grid Infrastructure and Distributed Energy: Edinburgh-based Mocean Energy, which works to deliver renewable ocean energy to power offshore industry, and Tulsa-based RyuGen Energy Solutions Inc., which works to turn underused commercial power into distributed AI infrastructure

Critical Minerals and Resource Security: Houston-based Resollant, which is working to produce battery-grade graphite and ultra-low-cost hydrogen, and Berkeley-based Sunchem, which provides precision separation of critical metals from sources including e-waste, evaporator scrap, solar panels, and mining ores and concentrates.

Last year, the Pilotathon named eight winners from the competition, which focused on the theme of "Energy Access and Resilience." See the winners here.

EnergyTech Cypher rebranded from EnergyTech Nexus earlier this year. The energy transition hub also launched Cephyron, EnergyTech Cypher's new investor relationship management platform, built specifically for energy and climatech founders.

Houston energy transition ecosystem rebrands as 'Energytech Cypher'

new look

Houston-based Energytech Nexus has rebranded.

The cleantech founders community will now be known as Energytech Cypher. Organizers say the new name was inspired by the Arabic roots of the word cypher, ṣifr, which is also the root of the word zero.

"A cypher is a key that unlocks what's hidden," Nada Ahmed, co-founder and chief revenue officer of Energytech Cypher, said in a news release. "And zero? Zero is where every transformation begins, the leap from 0 to 1, from idea to reality, from potential to power. We decode the energy transition by connecting the right founders, the right capital, and the right corporate partners at the right time, because the most important journey in energy is the one that takes you from nothing to something."

Energytech Nexus has rebranded to Energytech Cypher.

Co-founder and CEO Jason Ethier says that the name change better reflects the organization's mission.

"The energy transition doesn't have a technology problem. It has a connection problem," Ehtier added in the release. "The right founders exist. The right investors exist. The right partners exist. What's been missing is the infrastructure to bring them together—to decode the complexity, remove the friction, and make sure the best technologies find the markets that need them. That's what this community has always done. Energytech Cypher is the name that finally says it."

Energytech Cypher, previously known as Energytech Nexus, was first launched in 2023 and has grown from a podcast to a 130-member ecosystem. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, Solidec and many others.

It is known for its flagship programs like the Pilotathon, which connects founders with industry partners for pilot opportunities. The event debuted in 2024.

Energytech Cypher also launched its COPILOT Accelerator last year. The accelerator partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. The inaugural cohort included two Houston-based startups and 12 others from around the U.S.

It also hosts programs like Liftoff, Energy Tech Market, lunch and learns, CEO roundtables, investor workshops and international partnership initiatives.

Last year, Energytech Cypher also announced a new strategic ecosystem partnership with Greentown Labs, aimed at accelerating growth for clean energy startups. It also named its global founding partners, including Houston-based operations such as Chevron Technology Ventures, Collide, Oxy Technology Ventures, and others from around the world.

Houston energy expert looks ahead to climate tech trends of 2026

Guest Column

There is no sugar‑coating it: 2025 was a rough year for many climate tech founders. Headlines focused on policy rollbacks and IRA uncertainty, while total climate tech venture and growth investment only inched up to about 40.5 billion dollars, an 8% rise that felt more like stabilization than the 2021–2022 boom. Deal count actually fell 18% and investor participation dropped 19%, with especially steep pullbacks in carbon and transportation, as capital concentrated in fewer, larger, “safer” bets. Growth-stage funding jumped 78% while early-stage seed rounds dropped 20%.

On top of that, tariff battles and shifting trade rules added real supply‑chain friction. In the first half of 2025, solar and wind were still 91% of new U.S. capacity additions, but interconnection delays, equipment uncertainty, and changing incentive structures meant many projects stalled or were repriced mid‑stream. Founders who had raised on 2021‑style valuations and policy optimism suddenly found themselves stuck in limbo, extending runway or shutting down.

The bright spots were teams positioned at the intersection of climate and the AI power surge. Power demand from data centers is now a primary driver of new climate‑aligned offtake, pulling capital toward firm, 24/7 resources. Geothermal developers like Fervo Energy, Sage Geosystems and XGS did well. Google’s enhanced‑geothermal deal in Nevada scales from a 3.5 MW pilot to about 115 MW under a clean transition tariff, nearly 30× growth in geothermal capacity enabled by a single corporate buyer. Meta and others are exploring similar pathways to secure round‑the‑clock low‑carbon power for hyperscale loads.

Beyond geothermal, nuclear is clearly back on the strategic menu. In 2024, Google announced the first U.S. corporate nuclear offtake, committing to purchase 500 MW from Kairos Power’s SMR fleet by 2035, a signal that big tech is willing to underwrite new firm‑power technologies when the decarbonization and reliability story is compelling. Meta just locked in 6.6GW of nuclear capacity through deals with Vistra, Oklo, and TerraPower.

Growth investors and corporates are increasingly clustering around platforms that can monetize long‑duration PPAs into data‑center demand rather than purely policy‑driven arbitrage.

Looking into 2026, the same trends will continue:

Solar and wind

Even with policy headwinds, solar and wind continue to dominate new capacity. In the first half of 2025 they made up about 90% of new U.S. electricity capacity. Over the 2025–2028 period, FERC’s ‘high‑probability’ pipeline points to on the order of 90–93 GW of new utility‑scale solar and roughly 20–23 GW of new wind, far outpacing other resources.

Storage and flexibility

Solar plus batteries is now the default build—solar and storage together account for about 81% of expected 2025 U.S. capacity additions, with storage deployments scaling alongside renewables to keep grids flexible. Thermal storage and other grid‑edge flexibility solutions are also attracting growing attention as ways to smooth volatile load.

EVs and transport

EV uptake continues to anchor long‑term battery demand; while transportation funding cooled in 2025, EV sales and charging build‑out are still major components of clean‑energy demand‑side investment

Buildings

Heat pumps, smart HVAC, and efficient water heating are now the dominant vectors for building‑sector decarbonization. Heating and cooling startups alone have raised billions since 2020, with nearly 700 million dollars going into HVAC‑focused companies in 2024, and that momentum carried into 2025.

Hydrogen

The green hydrogen narrative has faded, but analysts still see hydrogen as essential for steel, chemicals, and other hard‑to‑abate sectors, with large‑scale projects and offtake frameworks under development rather than headline hype.

CCS/CCUS

After years of skepticism, more large CCS projects are finally reaching FID and coming online, helped by a mix of tax credits and industrial demand, which makes CCS look more investable than it did in the pre‑IRA era.

So, yes, 2025 was a downer from the easy‑money, policy‑euphoria years. But the signal beneath the noise is clear: capital is rotating toward technologies with proven unit economics, real offtake (especially from AI‑driven power loads), and credible paths to scale—not away from climate altogether.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.

Podcast: How AI-powered detection can prevent workplace accidents before they happen

now streaming

Workplace safety has always been reactive. Incidents happen, reports are filed, lessons are learned — sometimes too late. But what if safety wasn’t about reacting to accidents, but preventing them altogether?

In this episode of the Energy Tech Startups Podcast, Stephen Ojji, founder and CEO of VisionTech, challenges how high-hazard industries approach safety. His vision? AI-driven incident detection that doesn’t just monitor the workplace —i t actively prevents injuries, ensures compliance, and builds a stronger safety culture.

From Oil and Gas Safety to AI Innovation

Stephen’s journey into energy tech isn’t what you’d expect. Starting as a safety engineer in Nigeria’s oil and gas sector, his early career was focused on ensuring compliance, training teams, and reducing workplace risks. But he quickly realized a flaw in the system — many incidents weren’t being reported at all.

"Workers don’t always report hazards, and not because they don’t care," he explains. "Sometimes it’s fear of consequences. Sometimes it’s just human nature — we’re focused on getting the job done. But ignoring small risks leads to big accidents."

That’s where VisionTech’s AI-powered safety monitoring system comes in. Instead of relying on human reporting, VisionTech integrates with existing workplace cameras, using computer vision technology and AI to detect:

  • Spills, fire hazards, and safety violations in real-time
  • Workers at risk of injury due to incorrect lifting techniques or missing PPE
  • Trends in safety culture, helping companies address recurring risks

"Think of it like having an extra set of eyes that never blinks," Stephen says. "Not to police workers, but to protect them."

AI and Safety: Moving Beyond Compliance to Prevention

Unlike traditional workplace monitoring, VisionTech’s AI safety system doesn’t track individuals — it tracks behaviors. The system uses ghosting technology, ensuring that workers’ identities remain anonymous while hazards are flagged instantly.

This shifts the focus from penalizing mistakes to empowering safer work environments.

"Companies say they care about safety, but what does that really mean?" Stephen challenges. "If safety is the priority, why not use every tool available to protect workers before an accident happens?"

And here’s the kicker: VisionTech doesn’t just detect risks. It helps companies act on them.

Instead of logging safety incidents in spreadsheets that go unread, the system transforms safety data into actionable insights — identifying patterns, trends, and areas for improvement that help companies make real, lasting changes.

Why Now? The Urgency for Smarter Safety Solutions

With OSHA regulations tightening and ESG commitments pushing for stronger worker protections, industrial companies are under growing pressure to do more than just meet compliance standards.

At the same time, AI and machine learning have advanced rapidly, making AI-powered safety monitoring more affordable, scalable, and accurate than ever before.

"If we had tried to build this 10 years ago, it wouldn’t have worked," Stephen admits. "The technology wasn’t ready. The market wasn’t ready. But today? It’s the right time, and the right tool for a problem that’s been ignored for too long."

What’s Next for VisionTech?

Currently in the MVP stage, VisionTech is preparing for pilot programs with oil and gas companies to prove its impact in real-world environments. The plan? Scale beyond oil and gas into manufacturing, construction, and any industry where safety matters.

But for Stephen, this isn’t just about launching another safety product — it’s about changing how companies think about protecting their workers.

"Safety isn’t just a compliance box to check," he says. "It’s about people. If companies really believe that ‘our employees are our greatest asset,’ then investing in their safety should be the easiest decision they ever make."

This is a conversation you don’t want to miss.

Houston energy startup names former Cheniere execs to C-suite

new leaders

Houston-based energy infrastructure startup Joulent has brought aboard a new chief financial officer and new chief operating officer—both former executives at Houston-based Cheniere Energy.

The C-suite moves come three months after Joulent raised $1.75 billion from National Grid Ventures.

Michael Wortley joins Joulent as co-president and CFO. Wortley most recently was executive vice president and CFO at Cheniere, an LNG producer and exporter.

In conjunction with Wortley’s hiring, Brian Boland, who was Joulent’s interim CFO, has been named executive vice president, chief investment officer, and head of strategy.

Corey Grindal comes to Joulent as co-president and COO. Grindal most recently was executive vice president and COO at Cheniere.

“As Joulent evolves to meet the growing demand for power infrastructure, our expanded leadership team will help ensure we continue delivering the execution certainty our customers, partners, and investors expect,” Chris James, Joulent’s founder and CEO, said in a press release.

“Corey and Michael are accomplished operators with exceptional records of building and leading world-class energy infrastructure businesses, where they have embedded a culture defined by operational excellence and disciplined execution,” James added.

Joulet builds dedicated power-generating facilities that feed directly into data centers and other power-dependent facilities. This eliminates the need for companies to draw power from grids.

“With an initial multi-gigawatt development portfolio and strategic partnerships across the energy, infrastructure, and data center ecosystem, Joulent is helping remove power constraints to enable the next chapter of American innovation and U.S. reindustrialization,” the company says.

The $1.75 billion minority investment from National Grid Ventures complements Joulent’s existing partnerships.

Joulent, founded in 2023, emerged from stealth mode this summer. Cambridge, Massachusetts-based GE Vernova, a provider of energy equipment and services, and investment firm Engine No. 1 formed Joulent.

Joulent’s first project, the Project Kilby natural gas facility in West Texas, will be co-located with a Microsoft data center. It’ll deliver about 2.67 gigawatts of power under a 20-year deal between Microsoft and Energy Forge One, a subsidiary of Houston-based Chevron. Engine No. 1 and Chevron teamed up to build the plant.

Lithium refiner expands into Houston with new Energy Corridor office

new to hou

Battery-grade lithium carbonate manufacturer Stardust Power has expanded into Houston’s Energy Corridor, the company tells Energy Capital.

The company’s new office will serve as a project execution hub to support operations and planning for the company’s forthcoming lithium refinery in Muskogee, Oklahoma, according to a news release. The Greenwich, Connecticut-based, publicly traded company says the facility will be one of the largest lithium refining operations in the United States. The refinery is expected to have production capacity of up to 50,000 metric tons per year and seeks to address the critical shortage of U.S. lithium refining capacity.

Battery-grade lithium carbonate is commonly used in electric vehicle batteries and energy storage systems.

The company says it chose Houston as the location for its new execution hub for its rich history of expertise in engineering, a robust energy infrastructure ecosystem, and access to a leading talent pool for engineering, procurement and construction professionals. The Houston project hub will work closely with the company’s existing office in Oklahoma City.

“The Houston office strengthens our operational footprint at a critical phase of development,” Chris Celano, COO of Stardust Power, said in the release. “By building out a dedicated project management hub in one of the most experienced energy markets in the world, we are positioning the Company for execution as we advance the Muskogee refinery.”

Currently, the Houston office plans to accommodate a workforce of about 20 people with the possibility to add staff upon reaching project milestones, according to a representative from the company.

“This expansion reflects our commitment to deliver domestic, battery-grade lithium that supports U.S. energy security and industrial growth,” Celano added in the release.

In August, Stardust Power secured an offtake agreement to supply up to 20,000 metric tons of battery-grade lithium carbonate by 2030 from the Muskogee, Oklahoma, refinery to New York-based battery technology company Charge CCCV. Stardust reports that the deal adds to a separate non-binding agreement for up to 25,000 metric tons annually for 10 years with an undisclosed global trading company.

European cleantech company breaks ground on Houston manufacturing site

coming soon

Spanish renewable energy company Power Electronics broke ground on its new 53-acre Houston campus on Sept.24.

The new site is expected to create over 400 local jobs and deliver 40 gigawatts of production capacity per year. The company said in a news release that the campus is expected to be the largest manufacturing site for power conversion systems in the U.S. Power Electronics specializes in solar, energy storage, data centers and electrification technologies.

A completion date and operational start date have not yet been announced.

“For the first time in many years, the United States will be able to meet its growing need for sustainable power generation capacity and energy resilience through local manufacturing, supported by the most advanced technology in the world,” David Salvo, CEO of Power Electronics, said in the news release. “Our [40-gigawatt] Houston Campus will help shape the future of energy and AI growth globally."

Once operational, the manufacturing site will feature two buildings of approximately 150,000 square feet and 700,000 square feet. They will house production, logistics, R&D, corporate offices, training and electronic manufacturing departments.

The company says the Houston campus will be its most automated inverter production site by using advanced technologies in production to streamline day-to-day processes. Inverters convert direct current (DC) electricity that is generated by solar panels and batteries to alternating current (AC) electricity used by electrical grids.

Power Electronics' global headquarters is in Valencia, Spain, with U.S. operations in Houston, Tampa, and Gilbert, Arizona. Its North American headquarters is located at its existing North Houston office on East Airtex Drive. Community Impact News reports that the new manufacturing site is located in the Cy-Fair/Jersey Village area.

Power Electronics shared on LinkedIn that the new Houston campus represents its commitment to its American business and will allow it to serve the market with "greater scale, proximity and local expertise." It currently has more than 116 gigawatts installed in the U.S. and is working toward a global goal of 105 gigawatts of annual global production capacity.
