There’s a reason “carbon footprint” became a buzzword. It sounds like something we should know. Something we should measure. Something that should be printed next to the calorie count on a label.

But unlike calories, a carbon footprint isn’t universal, standardized, or easy to calculate. In fact, for most companies—especially in energy and heavy industry—it’s still a black box.

That’s the problem Planckton Data is solving.

On this episode of the Energy Tech Startups Podcast, Planckton Data co-founders Robin Goswami and Sandeep Roy sit down to explain how they’re turning complex, inconsistent, and often incomplete emissions data into usable insight. Not for PR. Not for green washing. For real operational and regulatory decisions.

And they’re doing it in a way that turns sustainability from a compliance burden into a competitive advantage.

From calories to carbon: The label analogy that actually works

If you’ve ever picked up two snack bars and compared their calorie counts, you’ve made a decision based on transparency. Robin and Sandeep want that same kind of clarity for industrial products.

Whether it’s a shampoo bottle, a plastic feedstock, or a specialty chemical—there’s now consumer and regulatory pressure to know exactly how sustainable a product is. And to report it.

But that’s where the simplicity ends.

Because unlike food labels, carbon labels can’t be standardized across a single factory. They depend on where and how a product was made, what inputs were used, how far it traveled, and what method was used to calculate the data.

Even two otherwise identical chemicals—one sourced from a refinery in Texas and the other in Europe—can carry very different carbon footprints, depending on logistics, local emission factors, and energy sources.

Planckton’s solution is built to handle exactly this level of complexity.

AI that doesn’t just analyze

For most companies, supply chain emissions data is scattered, outdated, and full of gaps.

That’s where Planckton’s use of AI becomes transformative.

  • It standardizes data from multiple suppliers, geographies, and formats.
  • It uses probabilistic models to fill in the blanks when suppliers don’t provide details.
  • It applies industry-specific product category rules (PCRs) and aligns them with evolving global frameworks like ISO standards and GHG Protocol.
  • It helps companies model decarbonization pathways, not just calculate baselines.

This isn’t generative AI for show. It’s applied machine learning with a purpose: helping large industrial players move from reporting to real action.

And it’s not a side tool. For many of Planckton’s clients, it’s becoming the foundation of their sustainability strategy.

From boardrooms to smokestacks: Where the pressure is coming from

Planckton isn’t just chasing early adopters. They’re helping midstream and upstream industrial suppliers respond to pressure coming from two directions:

  1. Downstream consumer brands—especially in cosmetics, retail, and CPG—are demanding footprint data from every input supplier.
  2. Upstream regulations—especially in Europe—are introducing reporting requirements, carbon taxes, and supply chain disclosure laws.

The team gave a real-world example: a shampoo brand wants to differentiate based on lower emissions. That pressure flows up the value chain to the chemical suppliers. Who, in turn, must track data back to their own suppliers.

It’s a game of carbon traceability—and Planckton helps make it possible.

Why Planckton focused on chemicals first

With backgrounds at Infosys and McKinsey, Robin and Sandeep know how to navigate large-scale digital transformations. They also know that industry specificity matters—especially in sustainability.

So they chose to focus first on the chemicals sector—a space where:

  • Supply chains are complex and often opaque.
  • Product formulations are sensitive.
  • And pressure from cosmetics, packaging, and consumer brands is pushing for measurable, auditable impact data.

It’s a wedge into other verticals like energy, plastics, fertilizers, and industrial manufacturing—but one that’s already showing results.

Carbon accounting needs a financial system

What makes this conversation unique isn’t just the product. It’s the co-founders’ view of the ecosystem.

They see a world where sustainability reporting becomes as robust as financial reporting. Where every company knows its Scope 1, 2, and 3 emissions the way it knows revenue, gross margin, and EBITDA.

But that world doesn’t exist yet. The data infrastructure isn’t there. The standards are still in flux. And the tooling—until recently—was clunky, manual, and impossible to scale.

Planckton is building that infrastructure—starting with the industries that need it most.

Houston as a launchpad (not just a legacy hub)

Though Planckton has global ambitions, its roots in Houston matter.

The city’s legacy in energy and chemicals gives it a unique edge in understanding real-world industrial challenges. And the growing ecosystem around energy transition—investors, incubators, and founders—is helping companies like Planckton move fast.

“We thought we’d have to move to San Francisco,” Robin shares. “But the resources we needed were already here—just waiting to be activated.”

The future of sustainability is measurable—and monetizable

The takeaway from this episode is clear: measuring your carbon footprint isn’t just good PR—it’s increasingly tied to market access, regulatory approval, and bottom-line efficiency.

And the companies that embrace this shift now—using platforms like Planckton—won’t just stay compliant. They’ll gain a competitive edge.

Tech entrepreneur turned climate investor is on a mission to monetize carbon removal

now streaming

The climate conversation is evolving — fast. It’s no longer just about emissions targets and net-zero commitments. It’s about capital, infrastructure, and execution at industrial scale.

That’s exactly where Yao Huang operates. A seasoned tech entrepreneur turned climate investor, Yao brings sharp clarity to one of the biggest challenges in climate innovation: how do we fund and scale technologies that remove carbon without relying on goodwill or government subsidies?

In this episode of the Energy Tech Startups Podcast, Yao sits down with hosts Jason Ethier and Nada Ahmed for a wide-ranging conversation that redefines how we think about decarbonization. From algae-based photobioreactors that capture CO₂ at the smokestack, to financing models that mirror real estate and infrastructure—not venture capital—Yao lays out a case for why the climate fight will be won or lost on spreadsheets, not slogans.

Her message is as bold as it is practical: this isn’t about saving the planet for the sake of it. It’s about building profitable, resilient systems that scale. And Houston, with its industrial base and project finance expertise, is exactly the place to do it.

The 40-Gigaton Challenge—and a Pandemic Pivot

Yao’s entry into climate wasn’t part of a long-term plan. It was sparked by a quiet moment during the pandemic—and a book.

Reading How to Avoid a Climate Disaster by Bill Gates, she came to two uncomfortable realizations:

  1. The people in power don’t actually have this figured out, and
  2. She would be alive to suffer the consequences.

That insight jolted her out of the traditional tech world and into climate action. She studied at Stanford, surrounded herself with mentors, and began diving into early-stage climate deals. But she quickly realized that most of the solutions she was seeing were still years away from commercialization.

So she narrowed her focus: no R&D moonshots, no science experiments—just deployable solutions that could scale now.

Carbon Optimum: Where Algae Meets Infrastructure

That’s how she found Carbon Optimum, a company using algae photobioreactors to remove CO₂ directly from industrial emissions. Their approach is both elegant and economic:

  • Install algae reactors next to major emitters like coal and cement plants.
  • Feed the algae with flue gas, allowing it to absorb CO₂ in a controlled system.
  • Harvest the algae and convert it into valuable commodities like bio-oils, fertilizer, and food ingredients.

It’s a nature-based solution, enhanced by engineering.
One acre of tanks can capture emissions and generate profit—without subsidies.

“This is one of the few solutions I’ve seen that can scale profitably and quickly,” Yao says. “And we’re not inventing anything new—we’re just doing it better.”

The Real Problem? It’s Capital, Not Carbon

As an investor, Yao is blunt: most climate startups are misaligned with the capital markets.

They’re following a tech startup playbook—built for SaaS, not steel. But building climate infrastructure requires a completely different approach: project finance, blended capital, debt structures, carbon credit integration, and regulatory incentives.

“Climate tech is more like real estate or healthcare than software,” Yao explains. “You don’t raise six rounds of venture. You build a stack—grants, equity, debt, tax credits—and you structure your project like infrastructure.”

It’s not just theory. It’s exactly how Carbon Optimum is expanding—through partnerships, offtake agreements, and real-world deployments. And it’s why she believes many climate startups fail: they don’t speak the language of finance.

Houston’s Role in the Climate Capital Stack

For Yao, Houston isn’t just a backdrop—it’s a strategic asset.

The city’s deep bench of project finance professionals, commodity traders, lawyers, and infrastructure veterans makes it uniquely positioned to lead the deployment phase of climate solutions.

“We’ve been calling it the wrong thing,” she says. “This isn’t just about climate—it’s an energy transition. And Houston knows how to build energy infrastructure at scale.”

Still, she notes, the ecosystem needs to evolve. Less education, more execution. Fewer workshops, more closers.

“Houston could be the epicenter of this movement—if we activate the right people and get the right projects over the line.”

From Carbon Capture to Circular Economies

The potential applications of Carbon Optimum’s algae platform go beyond carbon capture. Because the output—algae biomass—can be converted into:

  • Renewable oil
  • High-efficiency fertilizers (critical in today’s geopolitically fragile supply chains)
  • Food ingredients rich in protein and nutrients
  • Even biochar, a highly stable form of carbon sequestration

It’s scalable, modular, and location-agnostic. In island nations, Yao notes, these systems can offer energy independence by turning waste CO₂ into local energy and fertilizer—without needing to import fuels or food.

“It’s not just emissions reduction. It’s economic sovereignty through circular systems.”

Doing, Not Just Talking

One of Yao’s key takeaways for founders? Don’t waste time. Climate startups don’t have the luxury of trial-and-error cycles stretched over years.

“Founders need to get real about what it takes to scale: talent, capital, storytelling, partnerships. If you’re not ready to do that, maybe you should be a CSO, not a CEO.”

She also points out that founders don’t need to hire everyone—they need to tap the right networks. And in cities like Houston, those networks exist—if you know how to motivate them.

“It takes a different kind of leadership. You’re not just raising money—you’re moving people.”

Why This Episode Matters

This conversation is for anyone who’s serious about scaling real solutions to the climate crisis. Whether you’re a founder navigating capital markets, an investor seeking return and impact, or a policymaker designing the frameworks — Yao Huang offers a grounded, urgent, and actionable perspective.

It’s not about hope. It’s about execution.

Oxy's $1.3B Texas carbon capture facility on track to​ launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.

Fervo Energy selects Baker Hughes to provide supply geothermal tech for power plants

geothermal deal

Houston-based geothermal energy startup Fervo Energy has tapped Houston-based energy technology company Baker Hughes to supply geothermal equipment for five Fervo power plants in Utah.

The equipment will be installed at Fervo’s Cape Station geothermal power project near Milford, Utah. The project’s five second-phase, 60-megawatt plants will generate about 400 megawatts of clean energy for the grid.

Financial terms of the deal weren’t disclosed.

“Baker Hughes’ expertise and technology are ideal complements to the ongoing progress at Cape Station, which has been under construction and successfully meeting project milestones for almost two years,” says Tim Latimer, co-founder and CEO of Fervo. “Fervo designed Cape Station to be a flagship development that's scalable, repeatable, and a proof point that geothermal is ready to become a major source of reliable, carbon-free power in the U.S.”

Cape Station is permitted to deliver about two gigawatts of geothermal power. The first phase of the project will supply 100 megawatts of power to the grid beginning in 2026. The second phase is scheduled to come online by 2028.

“Geothermal power is one of several renewable energy sources expanding globally and proving to be a vital contributor to advancing sustainable energy development,” Baker Hughes Chairman and CEO Lorenzo Simonelli says. “By working with a leader like Fervo Energy and leveraging our comprehensive portfolio of technology solutions, we are supporting the scaling of lower-carbon power solutions that are integral to meet growing global energy demand.”

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company has surpassed $1 billion. In March, Axios reported Fervo is targeting a $2 billion to $4 billion valuation in an IPO.

Over the course of eight years, Fervo has raised almost $1 billion in capital, including equity and debt financing. This summer, the company secured a $205.5 million round of capital.

Houston-area sustainable steel company emerges from stealth with $17M in VC funding

heavy metals

Conroe-based Hertha Metals, a producer of substantial steel, has hauled in more than $17 million in venture capital from Khosla Ventures, Breakthrough Energy Fellows, Pear VC, Clean Energy Ventures and other investors.

The money has been put toward the construction and the launch of its 1-metric-ton-per-day pilot plant in Conroe, where its breakthrough in steelmaking has been undergoing tests. The company uses a single-step process that it claims is cheaper, more energy-efficient and equally as scalable as conventional steelmaking methods. The plant is fueled by natural gas or hydrogen.

The company, founded in 2022, plans to break ground early next year on a new plant. The facility will be able to produce more than 9,000 metric tons of steel per year.

Hertha said in a news release that its process, which converts low-grade iron ore into molten steel or high-purity iron, “doesn’t just materially lower cost and energy use — it fundamentally expands our capacity to produce iron and steel at scale, by unlocking a wider range of iron ore feedstocks.”

Laureen Meroueh, founder and CEO of Hertha, says the company’s process will fill a gap in U.S. steel production.

“We’re not just reinventing steelmaking; we’re redefining what’s possible in materials, manufacturing, and national resilience,” Meroueh says.

Hertha says it’s in talks with magnet producers — which make permanent magnets and magnetic assemblies from raw materials such as iron — to become a U.S. supplier of high-purity iron. In its next stage of growth, Hertha will aim to operate at a capacity of 500,000 metric tons of steel production per year.

The company won the Department of Energy's Summer Energy Program for Innovation Clusters (EPIC) Startup Pitch Competition last summer. Read more here.
