Building the world of low carbon cement | Ryan Gilliam, CEO of Fortera Aug 25, 2023

Show notes

In this week’s episode, we explore the world of cement. Concrete is the second most consumed material on earth behind water and is essential to the infrastructure that will enable the transition to renewable energy. But producing cement, which is the material that glues concrete together, is incredibly carbon intensive. As CEO of Fortera, Dr. Ryan Gilliam looks to nature and how coral and shells are strengthened by imbedding ambient carbon. Fortera’s first plant, in Redding, California, will come online by the end of 2023 and Fortera cement is construction ready.

Throughout the conversation, Dr. Gilliam discusses how he partners with existing concrete suppliers, why the first iteration of Fortera failed to gain traction, and how he has built a business savvy team to bring Fortera cement to market.

Going beyond megawatt hour matching | Katherine Collins, Hank He, Lee Taylor, Rob Threlkeld Jul 26, 2023

Show notes

For several years, well-intentioned companies seeking to reduce their emissions from electricity consumption – a primary component of their Scope 2 emissions – have bought Renewable Energy Credits (RECs) or signed Power Purchase Agreements (PPAs). Known as energy or megawatt hour matching, this approach, which forms the backbone of the Greenhouse Gas Protocol’s Scope 2 Market-Based Method accounting system, does not distinguish the time, location or emissions profile of a company’s electricity consumption from that of its REC and PPA interventions to offset this consumption.

But as different grids have decarbonized at different rates over the years, the emissions impact of a REC purchased or PPA signed in one location at a particular time no longer necessarily has a similar impact to RECs purchased or PPAs signed in different locations covering different periods of time. In essence, at least as it pertains to carbon impact, not every megawatt hour is created equal.

In this episode, recorded at the GreenFin 23 Conference in Boston, Chad leads a panel of industry experts – including Katherine Collins of Putnam Investments; Hank He of Tabors Caramanis Rudkevich; Lee Taylor of REsurety; and Rob Threlkeld of General Motors – on the deficiencies of energy matching, the benefits of a new approach known as carbon matching and the resulting implications for ongoing efforts to reform Scope 2 of the Greenhouse Gas Protocol.

How nanobubbles solve climate challenges | Nick Dyner, CEO of Moleaer Jul 14, 2023

Show notes

Nanobubbles provide an effective solution to many of the challenges of climate change. These nanoscopic bubbles are 2500 times smaller than a single grain of salt and can be formed with any gas. Unlike larger bubbles, they remain suspended in liquid longer and remain stable until they interact with surfaces or contaminants. Their size allows them to achieve dissolved oxygen levels many times greater than those achieved using traditional aeration technologies. With applications from industries including agriculture, aquaculture, oil and gas, mining, and municipal and surface water treatment, nanobubbles can improve energy efficiency, save water, and reduce chemical use.

In this episode Hilary Langer talks with Moleaer’s CEO Nick Dyner. Moleaer provides nanobubbles-as-a-service, nanobubble equipment, and water quality improvement around the world.

The essential role of RNG in the energy transition | Michael Bakas, Ameresco Jun 28, 2023

Show notes

Every community across the globe produces waste. This waste can come from landfills, decomposing food, animal manure, and wastewater sludge. As this waste decomposes, it emits natural gas – primarily composed of methane, which is a naturally occurring but very potent and harmful greenhouse gas. In fact, methane is nearly 30 times more potent at trapping heat in our atmosphere than carbon dioxide. Renewable Natural Gas (RNG) projects capture this methane before it harms our environment and repurposes it to create clean and reliable energy that is used to generate electricity, power our vehicles, heat our homes, cook our food, and many other productive purposes. In this episode, Chad and Gil speak with Michael Bakas, Executive Vice President at Ameresco, a leading cleantech integrator specializing in energy efficiency and renewable energy. Michael details the various RNG production pathways and revenue streams, discusses his views on RNG market growth drivers, and makes a compelling case for the essential role of RNG in the energy transition.

The Finless Foods sustainable seafood strategy | Shannon Cosentino-Roush May 31, 2023

Show notes

Seafood provides nearly 20% of the animal protein humans consume globally. This growing source of protein is also rather healthy with many of our nutrient-rich foods coming from aquatic creatures. But already, the supply of our wild capture seafood has flattened, meaning that the vast majority of our global fisheries today are being overfished in an unsustainable manner.

Fortunately, Finless Foods and other sustainable seafood startups are working to bring sustainability-driven innovation to the seafood space. With both plant-based and cell-cultured options, consumers are finally beginning to experience the taste and value of seafood alternatives that are better for our oceans and their inhabitants as well as our climate. In this episode, Chad Reed talks with Finless Foods’ chief strategy officer Shannon Consentino-Roush about the past, present and future of the sustainable seafood movement and industry.

Integrating emissionality into the Greenhouse Gas Protocol | Faraz Ahmad, Amazon Apr 20, 2023

Show notes

More than 90% of Fortune 500 companies report their emissions using the Greenhouse Gas Protocol (GHGP), which supplies the world’s most widely used greenhouse gas accounting standards. But despite significant advances in data analytics around emissions measurement, it’s been nearly a decade since the GHGP was last updated. Thankfully, the NGOs that manage the GHGP recently kicked off the update process, soliciting feedback from stakeholders across the spectrum.

In this episode, Chad Reed and HASI Strategic Advisor Brendan Herron speak with Faraz Ahmad, Head of Net Zero Grid for Amazon. Faraz dives deep into the efforts of the Emissions First Partnership, a consortium of companies working together to reduce their emissions with the most impactful clean energy projects and to move away from megawatt hour matching and toward integration of an emissions-based framework into the GHGP. Faraz also discusses how underserved regions – both across the globe and within the U.S. itself – could economically benefit from an emissions first approach to the energy transition.
