Rising risks facing solar projects | Jason Kaminsky, CEO of kWh Analytics
According to the International Energy Agency, the world is expected to build more renewable projects in the next five years as we have in the past 20. But this rapid and massive growth in the renewable energy space has proven increasingly challenging for insurers of these assets, who are struggling to deal with mounting losses from natural disasters (which themselves are often driven by climate change) as well as growing demand for new products that insure against other emerging risks such as production and revenue variability. In this episode, Chad Reed sits down Jason Kaminsky, CEO and co-founder of kWh Analytics, perhaps the leader in delivering data-enabled Climate Insurance for zero-carbon assets. In the discussion, Chad and Jason get into the weeds on the recent evolution of the Climate Insurance industry, kWh’s Fifth Annual Solar Risk Assessment as well as data-enabled solutions to address the most pressing risks facing the U.S. solar industry today.

Deploying a safer cold chain for vaccines, food, and planet | Manik Suri, CEO of Therma
We all depend on the cold chain to keep our foods, vaccines, and medical equipment safely chilled from production to use. This energy intensive process requires constant monitoring. As CEO of Therma, Manik Suri deploys small mobile sensors that monitor conditions to optimize energy efficiency and quality along the cold chain. His work is infused with his family’s legacy of service to others, and his team is dedicated to leveraging technology to improve the well-being of both people and planet. In this episode, Hilary Langer is joined by Therma CEO Manik Suri to discuss the impact of the cold chain on human health, food waste and the planet.

Credibly removing carbon at scale | Andreas Aepli, Climeworks
At this point, the science is very clear. If we want to limit global warming to 2 degrees above pre-industrial levels, we must not only reduce existing emissions, we must also at some point become net negative – meaning that we are removing more carbon from the atmosphere than we are putting into it. In this episode, Chad Reed sits down with Climeworks CFO Andreas Aepli to discuss the promise of Direct Air Capture (DAC) to provide a scalable, measurable and permanent solution for carbon removal. In addition to discussing how DAC works and both the DAC facilities Climeworks already has in operation and the DAC hubs in United States they are now developing, they delve into the viability of the business model for carbon removal, the need for supportive policy incentives and the imperative to establish transparency and trust for a truly scalable and tradable carbon removal credit market.

Going beyond megawatt hour matching | Katherine Collins, Hank He, Lee Taylor, Rob Threlkeld
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
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
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.
