Dan Yates, CEO of Dandelion Energy, discusses the benefits and features of residential geothermal energy and its connection to HVAC heat pump adoption. They cover Dandelion Energy's technologies, operations, business model, and recent tax incentives. They also explore factors influencing decision-making and the deployment of residential geothermal in the US Northeast. Additionally, they discuss the feasibility of geothermal energy in different areas of the US, project costs and benefits, and job opportunities in the geothermal energy industry.
Dandelion Energy focuses on residential geothermal energy solutions, utilizing a closed-loop system to access the stable temperature of underground soil for efficient heating and cooling in homes.
Geothermal heat pumps eliminate the need for outside units and offer consistent efficiency by extracting heat from the ground, aiming to replace traditional fossil fuel-based heating systems with an eco-friendly alternative.

Dandelion Energy: Bringing Residential Geothermal to Scale
Dandelion Energy is a startup focused on bringing residential geothermal energy solutions to scale. Unlike utility-scale geothermal, which taps into rare underground heat sources to generate electricity, residential geothermal utilizes a closed-loop system to access the consistent temperature of underground soil for heating and cooling functions in homes. Dandelion's mission is to use the ground as an insulator, leveraging it as a long-term store of solar energy to provide efficient heating and cooling. The company operates in the US Northeast, primarily in New York, Massachusetts, and Connecticut, where there is ample demand for geothermal due to high heating costs and state incentives. Dandelion is vertically integrated, handling everything from sales and marketing to drilling and installation. They offer financing options and have their own customized heat pumps. The company has been experiencing growth and is focused on expanding its direct-to-consumer retrofit business, as well as new construction projects and the development of its IP around heat pumps.
The Geothermal Advantage: Efficiency and Consistency
Geothermal heat pumps allow for efficient heating and cooling by utilizing the stable temperature of the ground. Cold is the absence of heat, and geothermal systems leverage this principle to transfer heat from the ground to the inside of a home in winter, and vice versa in summer. Dandelion's geothermal systems run a refrigerant cycle that passes through a loop buried underground, extracting heat from soil temperatures as low as 55 degrees Fahrenheit. This process eliminates the need for an outside unit and enables consistent efficiency, regardless of extreme weather conditions. By electrifying heat, Dandelion aims to replace traditional fossil fuel-based heating systems, such as natural gas or oil, with an eco-friendly and cost-effective alternative.
Market Expansion and Business Model
Dandelion primarily serves the US Northeast, which has a high concentration of homeowners using heating oil and propane. However, they can deploy geothermal systems nationwide as the technology works in various geologies and climates. The company has been successful in acquiring customers through digital marketing channels and has a direct-to-consumer approach. They offer financing options and have developed partnerships with developers for new construction projects. Dandelion's business model is vertically integrated and profitable at each stage, including heat pump manufacturing, installation, and sales. Incentives, such as the Investment Tax Credit and state-level incentives, significantly reduce the cost for homeowners, making geothermal systems more affordable.
Challenges and Future Outlook
Dandelion's main challenge lies in the operational complexity of its business, which requires smooth execution at every stage to generate revenue and profit. However, the regulatory trend is in their favor, with increasing state-level incentives and a growing recognition of the need to transition away from fossil fuel-based heating systems. Dandelion aims to continue its growth in the direct-to-consumer retrofit business, expand its new construction projects, and further develop their heat pump IP. They are always looking for talented individuals to join their team, and they emphasize the importance of spreading awareness about geothermal as a viable option for homeowners.
Dan Yates is the CEO and Chairman of Dandelion Energy, a Series B Stage startup deploying solutions for residential geothermal energy.
As Dan explains it, residential geothermal distinguishes itself from utility-scale geothermal by not aiming to exploit a scarce, underground heat source for electricity generation through turbines. Instead, the process involves circulating an aqueous solution through a closed loop underground. This allows the system to harness the stable temperature of the soil beneath and employ it for both heating and cooling functions in a residential ground source heat pump. Essentially, residential geothermal aligns with the trajectory of residential HVAC heat pump adoption, serving as a means to maintain a dependable and efficient temperature for optimal heat pump performance.
Dan is a repeat guest on My Climate Journey. He joined Jason way back on Episode 7 to recount his journey as the Co-founder and the CEO of Opower. Dandelion's Co-founder, Kathy Hannun, was also on the pod way back on Episode 35. A lot has changed in that time.
In today's conversation, we touch a bit on Dan's Opower journey, but most of the time is spent on Dandelion and geothermal. We also cover Dandelion's current geographic focus areas, the technologies it has developed, how they operate the company, the business model, the recent tax incentives from the Inflation Reduction Act and other legislation that have benefited the company, and so much more.
