Open Circuit: Jigar, Katherine, and Stephen are back
This week, we’re featuring an episode of Open Circuit, a new show from Latitude Media that reunites Jigar Shah, Katherine Hamilton, and Stephen Lacey.
Many listeners may remember them from The Energy Gang, a show they co-hosted for eight years.
They are back together, co-hosting a weekly roundtable that will cover the latest news – to explain what's really accelerating the energy transition, from technological leaps and supply chain shifts, to market upheavals and policy uncertainty.

The first commercial construction project for low-carbon cement
In May 2024, Yanni Tsipis was watching as his team prepared to pour a low-carbon version of concrete — one that had never been used in a commercial project. As senior vice president of WS Development, he was in charge of the team building Boston’s largest net-zero office building for operating emissions (not embodied emissions), and he had spearheaded an effort to use a new type of low-carbon cement from a startup called Sublime Systems.
It's hard to understate how big of a deal it is for the construction industry to try a new version of cement. It’s the glue that holds concrete particles together, and the recipe used today has barely changed since 1824. It's incredibly versatile stuff, but making it accounts for nearly 8% of global emissions, so there's pressure on the industry to clean up. But with the literal foundations of buildings, bridges, and roads at stake, you can understand why the industry might be slow to change.Â
But Yanni's team wanted to try.Â
In this episode, Lara talked to Yanni about the journey to the first commercial deployment of this low-carbon cement. He talks about the economics of cement, securing enough material in time to meet construction deadlines, and earning buy-in from WS Development’s internal team, plus their long list of contractors and subcontractors. It’s a case study in finding the right customer for a first-of-a-kind climate tech project.

Pioneering one of the first IRA tax credit transfers
When Chris Taylor and his team at GridStor were building Santa Barbara county's largest battery storage project in Goleta, CA they saw an opportunity: become one of the first companies to transfer tax credits under the newly passed Inflation Reduction Act. But there was no playbook to follow.
Instead of working with smaller, specialized investors, GridStor took an unconventional approach. They went straight to JP Morgan, one of the largest tax credit investors in the country, to prove that battery storage projects could work with mainstream financial institutions. The strategy involved navigating complex legal requirements, securing specific opinion letters, and creating a framework that other companies could follow.
In this episode, Lara Pierpoint talks to Chris Taylor, CEO of GridStor, about executing this groundbreaking financial deal while simultaneously building a 60-megawatt battery storage facility. They discuss the challenges of pioneering new financial territory, working with major financial institutions as a startup, and what successful tax credit transfers could mean for scaling clean energy projects.

Building the world’s biggest DAC facility
On Christmas Eve 2023, Doug Chan wasn't celebrating with family. Instead, he was in Hellisheiði, Iceland with his team, preparing to commission Mammoth — what would become the world's largest operational direct air capture facility.
Getting there wasn't easy. After building two successful smaller plants, Climeworks faced its biggest challenge yet in attempting a 10x scale-up of its Orca plant. When the team broke ground, they discovered issues with their newly designed equipment that forced tough decisions. And Iceland's harsh winter conditions complicated both construction and operations.
In this episode, Lara Pierpoint talks to Douglas Chan, chief operations officer at Climeworks, about proving and scaling direct air capture technology. They discuss managing technology risks, choosing the right partners — and what's next as Climeworks plans for an even bigger facility in Louisiana.

A complex path for building heat batteries
In 2022, John O’Donnell and Peter von Behrens figured out how to design a heat battery that would deliver heat at very high, constant temperatures. The breakthrough came on the heels of two years of research and development, some of which took place in Peter’s garage.Â
Now, John and Peter were ready to prove their technology at commercial scale. So they approached a long-time innovation partner, Calgren Renewable Fuels, about deploying a 2-megawatt-hour heat battery for industrial heat delivery in Calgren’s Pixley, California plant.
That’s when the next wave of problem solving started. It turns out, designing the technology was just half the battle. Manufacturing and installing a commercial scale demonstration proved harder than expected. In October 2023, they started on a six-month construction project that threw a myriad of challenges at the new start-up.Â
In this episode, Lara Pierpoint talks to John O’Donnell, co-founder and chief innovation officer at Rondo Energy, about the bumpy road of building a first-of-a-kind commercial demonstration. They cover things like the structural engineering challenges of scaling a new technology, and finding the right construction partner. Plus, John explains what new design specs mean for the company going forward.Â
