#257 Betting on $2 Trillion in Climate Infrastructure & Lessons from the DOE Loan Programs Office | Brendan Bell (Aligned Climate Capital)
8/20/2025
What does it take to scale the clean energy transition—both at the bleeding edge of new technology and in the nuts-and-bolts of infrastructure?
Today’s episode dives into the nuanced world of climate finance and infrastructure with Brendan Bell, Chief Operating Officer and Partner at Aligned Climate Capital. Unlike most investors who play in either venture or infrastructure, Align straddles both worlds, backing early-stage companies while also owning and operating clean energy assets.
Brendan shares his unusual path from the Sierra Club to the U.S. Senate, the Department of Energy’s Loan Programs Office, and now into the private sector. Along the way, he offers candid insights into what makes a strong infrastructure investment, how venture-backed technologies eventually scale into bankable assets, and why understanding both sides of the capital stack is critical to accelerating the clean energy transition.
This is a masterclass on the interplay between policy, venture innovation, and hard infrastructure. If you’ve ever wondered how moonshot technologies meet the realities of capital markets and project finance, this conversation will give you the inside view.

#256 Soil Health, Carbon Markets & Measuring the Hidden Climate Solution Beneath Our Feet | Chris Tolles (Yard Stick PBC)
8/13/2025
How can we fight climate change by focusing underground?
It turns out one of the biggest untapped climate solutions isn’t in the air—or in the trees, it’s in the soil beneath our feet. Today’s guest has developed a game-changing way to measure and protect soil organic carbon, helping farmers, agribusinesses, and carbon markets work together for climate impact and economic resilience.
Our guest is Chris Tolles, Founder & CEO of Yard Stick PBC.
Some quotes to hook you:
“Soils store way, way more carbon than all the trees and plants and animals combined.”
“If you want to sell soil carbon credits, you’ve got to measure soil carbon—accurately and at scale.”
“Healthy soils aren’t just about climate—they’re about keeping Cheerios on the shelves.”
“Identify the application of your technology that helps someone make money or save money—that’s what all businesses do.”

#251 How to Fix a Quarter Trillion Solar Assets at Scale | Nikhil Vadhavkar (Raptor Maps)
7/14/2025
In this episode, we sit down with Nikhil Vadhavkar, co-founder and CEO of Raptor Maps, to uncover how the company is tackling the invisible crisis in clean energy: operational inefficiency across $250B+ worth of solar assets.
Nikhil explains why the solar industry’s problems aren’t just about building more — they’re about getting the existing infrastructure to perform. From labor shortages to rising insurance costs, from underperforming fields to unscalable maintenance methods, Raptor Maps is turning traditional solar operations on its head.
Their secret? A software platform built on digital twins, computer vision, and robotics that lets field techs do more of what matters.
You'll hear how Raptor Maps found product-market fit by replacing the most dangerous and manual tasks on solar farms with drone- and robot-driven workflows, and how that foundation has evolved into an AI-ready platform used across tens of gigawatts of global deployments. Nikhil shares the journey from MIT and NASA to Y Combinator and utility-scale solar, reflecting on what it means to build something technically excellent, deeply customer-embedded, and truly scalable.

#247 Could EVs + Demand Response Solve Grid Flexibility? | Joseph Vellone (ChargeScape)
5/28/2025
What’s up, everyone!
Today we’re sharing an episode with Joseph Vellone, the CEO of ChargeScape — a Joint Venture between Ford, Honda, BMW, and Nissan.
-----
Listen on: Apple Podcasts | Spotify | YouTube | Pocket Casts
-----
As the grid continues to buckle under the pressure of ever-increasing demand, it’s more important than ever to find ways to manage the existing load.
However, it’s not all bad. One of the main demand drivers might be the core solution to these demand problems—namely, EVs, when paired with smart charging software.
You see, all these EVs are essentially backup batteries. Currently, not all are equipped with bi-directional charging, but most new vehicles hitting the roads are.
So, not only can a smart charging software, managed by utilities, alleviate demand on the grid, it can also pull energy from the vehicles when the time is right (again, when the hardware capabilities are present).
-----

This fundamentally shifts our perspective on vehicles. Instead of a cost center, it could earn you money by purchasing cheap energy, or charging on solar for free, and selling back to the grid at peak demand times.
This is the type of utopian future we work towards — and the best part, it’s becoming reality in front of us.

5/21/2025
Today, we’re speaking with Sophie Purdom, Managing Partner of Planeteer Capital.
After co-creating CTVC with Kim Zou, the climate deals and deep-dives newsletter that has become canon in climate, with 75k+ readers, Sophie announced Planeteer Capital.
(We discussed on the pod)
They’ve closed the first fund at an exceptional $55m (🤯) and are going full speed with their investing thesis. They are focused on investing in companies at the incorporation stage, something they have been able to do well given the history and network that Sophie has.
Aside from announcing the fund, teasing the future of Planeteer, and discussing their unique advantage, Sophie gave us some insights on where the market is now.
One thing that surprised us is how, despite all the negative news, more deals are being done year over year than in years past.
Sophie shares the 4 types of climate tech founders, what they look for picking the right team, and core things to get right when navigating the climate capital stack.

What’s up, everyone!
Today, we have a great episode with Haroon Inam & Michael Wood III from DG Matrix. We’re talking about a simple technology that can fundamentally reshape the energy industry by transforming electricity more efficiently and with way less physical space than what’s been done traditionally.
Take an EV charger, for example. You need to get the exact electricity flow right. Usually, that would take a few parking spaces’ worth of transformers. With DG Matrix, you can do it with a simple power stand smaller than your refrigerator.
This is still the case even if you’ve got solar, batteries, or other distributed resources all mixed in together. They can handle all the streams of electricity in and out.
It’s clear the industry is loving this too. They have over $1bn of pipeline to date.
We got Haroon and Michael, so it’s a great episode.

#243 Battery Storage Supply Chains & Future in US-China Trade War | Danny Lu | Powin

What’s up, everyone!
Today, we have a great episode with Danny Lu from Powin. Powin is a leading provider of BESS, w/ 8 GWh of systems built and 9 in the pipeline.
As the Trump admin pushes for more drilling and a seemingly anti-clean energy policy (despite that not being the definition of abundance) we are seeing the value of battery storage. Prior to tariffs, building a speaker plant would be more expensive and take longer than building energy storage systems to manage grid flexibility issues. (It’s tbd what the situation will be with huge Chinese tariffs).
Powin has years of experience working in this space to solve supply chain issues and is always improving its business to adapt to whatever battery chemistry is most feasible and affordable for its clients.
Given all this, it was great to speak with someone who can help us understand where the market is going and what the key challenges and opportunities are that lie ahead.

#241 The Biz Model Making eFuels Pencil Out | Joe Rodden (Lydian)
4/9/2025
Follow us on YouTube
---------
Today, we have a great episode with Joe Rodden from Lydian. And we are talking all things eFuels and their story.
Lydian uses Co2, Water, and abundant Green Energy to create eFuels/SAF. And because of their flexible run method, they can do it profitably, consistently.
In the recent past there has been a huge demand for SAF that has been hard for major airlines to procure. In part because the technology was not there, but mostly because there were no plants up and operating.
SAF plants are assumed to look like chemical production facilities… ie: always on. This way the cost of the investment is paid back soon.
Lydian made sure they used inexpensive materials to create their system. And they made it to start and stop whenever there is excess electricity being produced. It’s a game changer.
On top of this, Joe has a great story.
A story that I’m sure you’ll enjoy on today’s episode. Let us know your thoughts by leaving a comment and giving us 5 stars on your favorite podcast app.

#240 Bulldozing in a New Era of Climate Tech Investing & Tech-Enabled Investing | Andrew Chan from Atas VC
4/2/2025
Today, we have a great episode with Andrew Chan from Atas Ventures.
Surprise surprise…we’re continuing the conversation about the climate tech vibe shift, climate tech 3.0, climate risk…whatever you want to call it.
However, our conversation with Andrew Chan of Atas Ventures is a little bit different. Andrew has, from the very beginning, thought about climate investing from first principles, placing profitability and tangible impact at the core of his strategy. He refers to this next wave as "Climate 3.0," an evolution beyond traditional impact investing towards applied technologies like robotics, IoT, and advanced energy solutions.
Our conversation today focuses on these themes, including how venture capital can meaningfully intersect with antiquated industries such as mining, agriculture, and manufacturing to drive both profits and genuine environmental outcomes. Andrew also shares why the venture capital playbook may need to evolve, emphasizing smarter portfolio construction, disciplined investing, and leveraging real-world experience to build lasting companies.
Overall, it's an amazing episode and we're really excited to share this with you.
Sidenote, we recorded this remotely while Andrew was traveling—he joined us from Bangor, Maine. If you'd like to watch, check it out on YouTube. (Also, be sure to give us a follow on YouTube to help us grow the channel!)

#239 Climate Risk, a New Era for Climate Tech | Grace & Adam from Equal Ventures
3/26/2025
📺 Watch on YouTube
What’s up, everyone!
Today we have a great episode with Grace Penders and Adam Chadroff from Equal Ventures. If you're not familiar with Equal, I recommend checking out episode 116 where we had on Rick Zullo, the Founder of Equal.
Today, we're continuing the conversation about the climate tech vibe shift. However, our conversation with Equal is a little bit different. Equal has, from the very beginning, had a thesis broader than just climate. One of those other areas is insurance. This is an area that is increasingly intersecting with climate. This is becoming especially acute given the rise in natural disasters and the catastrophic financial impacts that follow.
Our conversation today focuses on these themes as well as what the insurance industry’s role is in helping solve the climate investing challenge. There are plenty of ways. This is playing into how governments engage.
Overall, it's an amazing episode and we're really excited to share this with you.
Sidenote, we recorded this in person in the equal offices during my recent visit to New York. So if you'd like to watch, check it out on YouTube. (Also, be sure to give us a follow on YouTube to help us grow the channel)

#238 ClimateTech is Mainstream, so is The Vibe Shift | Tommy Leep (Jetstream)
3/19/2025
📺 Watch on YouTube
Hey everyone! Today we’ve got a great episode with Tommy Leep from VC, Jetstream. Some of his PortCos include David Energy, Pachama, Rhizome, and past pod guests Pathways & Glacier.
He’s been on the show in the past with some great advice on fundraising. Check it out — episode 85.
#85 How to Raise Money for your ClimateTech Startup w/ Tommy Leep, founder of Jetstream VC
Recently there have been a bunch of people shifting their focus or branding to be more inclusive and not always sound ‘pure climate tech’ — Tommy is one of those people. He recently claimed “ClimateTech is Mainstream now.” Because of it, he’s broadening his fund thesis.
This is the first of at least two conversations on this exact topic (stay tuned for next week’s episode with Grace and Adam from Equal Ventures).
