This past week, CERAWeek 2025 brought together over 10,000 leaders from more than 2,000 companies and 80 countries in Houston, all focused on the future of energy. This year’s theme, “Moving Ahead: Energy Strategies for a Complex World,” captured the tension between energy security, affordability, and decarbonization—three priorities that cannot exist in isolation.
At Energy Capital Ventures (ECV), we champion Green Molecules™ as a critical pillar of the future energy system. These low-carbon fuels, feedstocks, and emissions management solutions (like hydrogen, renewable natural gas, and carbon capture-based products) are essential for ensuring a clean, affordable, and secure energy transition. From hydrogen production costs to the role of biotech in carbon-negative fuels, Green Molecules were embedded in the discussions across every major theme at CERAWeek. Below, we break down the key takeaways from the conference and what they mean for the Green Molecules™ economy.
Affordability was front and center at CERAWeek, as the cost of the energy transition remains a global concern. Without affordability, there is no transition—households, industries, and governments cannot embrace clean solutions that are economically unviable. U.S. Energy Secretary Chris Wright underscored this, noting that “over 20% of Americans struggle with high energy bills”, reinforcing that cost must be a core metric for evaluating new energy solutions.
This is precisely why Green Molecules must be at the heart of the affordability conversation. While wind and solar have driven down electricity costs in many regions, not all sectors can be electrified efficiently. Heavy industry, long-haul transport, and heating—which rely on fossil fuels today—require drop-in, low-carbon replacements like clean hydrogen, sustainable fuels, and carbon-derived chemicals. If these industries are forced to transition without affordable alternatives, we risk economic stagnation and supply chain disruptions.
Saudi Aramco CEO Amin Nasser captured this challenge well: "With the winds of history in our sails again, let’s use our industry’s vast experience and practical expertise to usher in a truly golden new era of abundant, affordable and sustainable energy for all." His call to action aligns with what we see happening in Green Molecules—advancing solutions that use existing infrastructure while lowering emissions and costs.
The momentum behind Green Molecules is clear, but it’s capital and policy frameworks that will determine how affordable these solutions become. Scaling green hydrogen, biofuels, and captured carbon products requires both investment and regulatory clarity. One of the strongest takeaways from CERAWeek is that the capital transition must align with affordability—funding must flow toward practical, scalable Green Molecule solutions rather than theoretical bets.
CERAWeek’s Innovation Agora showcased the most exciting developments in energy, with AI, biotech, and carbon management emerging as key enablers of low-carbon fuels and emissions reduction technologies. As Daniel Yergin, Vice Chairman of S&P Global, put it: “When it comes to charting pathways to the energy future, change is proving to be the one constant.”
For Green Molecules, this innovation is happening at the intersection of chemistry, data, and synthetic biology. AI is now being deployed to optimize hydrogen production, carbon capture efficiencies, and bio-based fuel synthesis. One of the most promising frontiers? Biomanufacturing carbon-based fuels and materials.
Moji Karimi, CEO of Cemvita, a leading biotech company using microbes to convert CO₂ into valuable chemicals, highlighted this at CERAWeek:
“What’s so amazing about synthetic biology is that humans are just scratching the surface of what’s possible.”
The key takeaway? Nature has already solved many of the challenges of carbon utilization—we just need to scale those solutions commercially. Cemvita, an ECV portfolio company, is proving this by using engineered microbes to turn waste CO₂ into bio-based oil—a scalable pathway for carbon-negative fuel production.
Meanwhile, in hydrogen production, the industry is moving away from the "color debate" (green, blue, turquoise, etc.) and toward carbon-intensity-based valuations. As one panelist put it: "There’s no room for the hydrogen rainbow in a net-zero future. What matters is how much carbon it emits—not what we call it."
This shift is critical. The sooner we standardize carbon intensity metrics, the faster we can drive down costs, scale production, and integrate hydrogen into industrial supply chains.
While optimism about Green Molecules ran high, CERAWeek panelists were clear that scaling these solutions will not be easy. The biggest barriers? Infrastructure, permitting delays, and capital bottlenecks. These hurdles are especially relevant for hydrogen hubs, carbon capture projects, and sustainable fuels, which require large investments before they reach commercial scale.
Amin Nasser delivered one of the most striking warnings:
"There is more chance of Elvis speaking next than the current plan working."
His point? The current pace of infrastructure development is far too slow to meet the world's energy needs while reducing emissions.
We see this firsthand in hydrogen project delays, slow CCUS adoption, and underdeveloped carbon markets. For Green Molecules to succeed, policymakers must create investment-friendly regulations that provide long-term certainty for infrastructure developers.
Permitting reform was also a hot topic, as industry leaders called for faster approvals for carbon storage wells, hydrogen pipelines, and biofuel facilities. Without regulatory streamlining, many Green Molecule projects will remain stuck in the "valley of death"—too costly for venture investment, but too early for project finance.
At ECV, we invest in solutions that make Green Molecules scalable and cost-competitive. Three of our portfolio companies, Cemvita, Highwood Emissions Management, and Sapphire Technologies had strong presences at CERAWeek:
Cemvita is shaping the future of Sustainable Aviation Fuels (SAF) with its strategic foresight research on cost, regulation, and innovation in biofuels. At CERAWeek, CEO Moji Karimi shared insights on how feedstock sustainability, policy shifts, and renewable electricity costs will dictate SAF’s growth through 2035. Cemvita’s CemOil™️, a drop-in fuel for HEFA refineries, is already scaling, with its first commercial plant in development in Brazil in partnership with Be8.
Highwood Emissions Management is leading the methane data revolution, helping operators turn emissions data into real, actionable reductions. At CERAWeek, Highwood took the stage at EDF’s Methane Innovation House, Canada House, and Agora Pods, showcasing its Emissions Intelligence Platform (EIP). CEO Jessica Shumlich emphasized that data harmonization is critical for operators to integrate satellite, ground, and sensor-based methane data at scale. As public emissions data becomes more accessible, companies must proactively manage their emissions to stay ahead of increasing transparency and regulations.
Sapphire Technologies is advancing energy efficiency in natural gas infrastructure through its Turboexpander technology, which captures wasted pressure energy and converts it into clean electricity. At CERAWeek, CEO Freddie Sarhan and VP Ayman Zeitoun engaged with industry leaders at Chevron’s Partner House, highlighting how energy recovery solutions can make natural gas more efficient and sustainable. As the push for decarbonization and operational efficiency grows, Sapphire’s innovations offer a practical, cost-saving pathway to reducing emissions in gas infrastructure.
All of these companies embody ECV’s vision for Green Molecules—leveraging cutting-edge science to make energy cleaner, without compromising affordability or reliability.
CERAWeek 2025 made it clear: Green Molecules are not optional—they are necessary. Whether in hydrogen, biofuels, or carbon utilization, these solutions provide the affordable, scalable, and reliable energy transition pathways we need.
The biggest takeaways?
1. Affordability must remain the cornerstone of decarbonization. Without cost-competitive Green Molecules, industries will struggle to transition.
2. Innovation—especially in biotech, AI, and emissions management—is accelerating the deployment of Green Molecules.
3. Challenges remain, but infrastructure and permitting reforms can unlock rapid scaling.
As Energy Capital Ventures, we are proud to invest in and advocate for Green Molecules, ensuring that the energy transition is both practical and profitable. CERAWeek 2025 reaffirmed that we are on the right path—now, it's about execution.
