There is a wealth of knowledge and expertise that currently exists in the well and geothermal industry. Rather than try to replicate this extensive experience, Darcy’s approach is to leverage this knowledge and capability by employing its business model of using the “same People, same Processes and same Partners” to develop and deliver its sustainable heating and cooling system. Darcy has established deep working relationships with several industry-leading experts and complements their well-established practices with our hydrological and geological expertise to create and deliver the most practical and sustainable heating and cooling solution.
A full service well contractor established in 1948, Bergerson Caswell has been installing geothermal systems since 1987. They maintain strong connections with the National Groundwater Association, including its recent involvement as the association president. Bergerson’s diverse experience and extensive national contacts are helping Darcy Solutions navigate technical, regulatory, and commercial hurdles.
Midwest Mechanical Solutions
Founded in 1997, Midwest Mechanical Solutions specializes in engineered solutions for sustainable design and efficient HVAC systems. The company develops and maintains relationships with commercial and industrial building owners, consulting engineers & contractors to solve for unique building needs.
The Glacier Group
A manufacturer’s representative specializing in innovative, energy-efficient HVAC systems for the commercial and industrial markets. Glacier focuses on providing clients with forward-looking solutions supported by expert applications knowledge and first-class customer service.
Established in 1904, Johnson Screens is the leading international manufacturer of water well screens, well casings, and accessories for municipal and industrial wells. Additionally, they publish the industry standard textbook on well construction, Groundwater and Wells. Johnson’s team provides design analysis, technical support, and the industry’s most trusted experts.
DOE works with stakeholders to develop programs and policies to facilitate the deployment of advanced clean energy technologies that make energy more affordable and strengthen the reliability, resilience, and security of the U.S. electric grid. In support of that mission, Darcy has received a Phase I Small Business and Innovation Research (SBIR) grant.
NSF “supports R&D of deep technologies – those that are based on discoveries in fundamental science and engineering.” Darcy’s Phase I SBIR grant from NSF is supporting the continued development of Darcy’s technology. With additional NSF funding, we participated in NSF’s intensive Innovation-Corps program where we developed market insights from more than 100 prospective customers and partners.
The USDA SBIR program focuses on transforming scientific discovery into products and services with commercial potential and/or societal benefit. Unlike fundamental research, the USDA SBIR program supports small businesses in the creation of innovative, disruptive technologies and enables the application of research advancements from conception into the market. Darcy has received a Phase I SBIR grant from the USDA.
Evergreen Climate Innovations (formerly Clean Energy Trust), Darcy’s first investor, provides catalytic capital and support to startups working on solutions for clean energy, decarbonization, and environmental sustainability. They are providing us specific insights on our business, and their targeted introductions across the electric utility ecosystem are extremely helpful in connecting us with potential industry partners.
There are several important considerations when thinking about de-carbonizing building heating and cooling and the electrification of HVAC technology. Providing the most energy efficient technology can help reduce system load and avoid the need for additional power. generation and transmission investments. Similarly, utilizing technology that helps reduce peak electrical demand and smooth energy use can also enhance system load factors and mitigate the need for additional generation and transmission capacity.
Heat pumps are essentially air conditioners that can be operated in one direction to provide cooling and operated in the opposite direction to provide heating. Heat pumps use refrigerants, which take advantage of the ideal gas law (PV = nRT) and move heat around through 4 steps.
For cooling, a heat pump works as laid out in this table.
The system works in reverse when the building needs to be heated.
The geothermal energy that occurs across various parts of the globe, such as Iceland, can offer 2 important and beneficial uses. High temperature geothermal (>360 F) can be used to create steam which in turn can be used to generate electricity. Lower temperature (68 – 302 F) geothermal can be used for direct heating, as the ancient Romans did.
Darcy’s technology utilizes what is really a form of solar energy that is stored in the shallow earth. Groundwater temperatures are relatively stable year-round, and typically reflect the average annual temperature for the area, ranging from 45 degrees F in the northern part of the continental U.S. to 75 degrees F in the southern part of the country. HVAC equipment, such as a heat pump, is designed to supplement these temperatures to provide the desired level of heating or cooling.
There are two major benefits.
The first benefit is that a system does not lose efficiency over the course of a season due to the gradual decrease in temperature while heating or a gradual increase in ground temperature while cooling (as happens in traditional geothermal). Maintaining consistent efficiency helps reduce electricity use and cost.
The second benefit is that a system can be designed to deliver cooling only or heating only without concern for gradual increase (or decrease) in underground temperature over years of operation. This flexibility enables the incorporation of creative heating or cooling systems (e.g., a cooling only system with the use of chilled beams, a DOAS, and no heat pump) for which energy savings can be significant, sometimes as much as a 70% reduction vs. conventional systems.
