It has the potential to generate 90 gigawatts of clean, dispatchable power, equivalent to approximately 12% of the electricity generated in the United States in 2015, through the improvement and development of technologies related to enhanced geothermal systems (EGS). geothermal energy, creating opportunities for a variety of applications, including geothermal heat pump systems and direct-use markets. These advances open the door to reducing emissions and offer sustainable solutions for urban, rural and remote communities.

Lauren Boyd explores the field of geothermal energy, distinguishing between conventional geothermal resources and Enhanced Geothermal Systems (EGS). While conventional resources are limited to specific areas with natural hot water sources, EGS allows for the creation of man-made reservoirs. By injecting fluids into hot rocks, EGS increases the efficiency of heat release, allowing energy to be generated from previously untapped regions.

Geothermal energy has unique properties that make it an invaluable asset in the energy transition. Geothermal power plants provide robust, durable, flexible and dispatchable electricity that ensures reliable electricity supply. With their high power factor and operational flexibility, geothermal power plants outperform wind and solar plants, making them ideal for balancing daily and seasonal loads, especially in areas where renewable energy sources are intermittent.

Geothermal energy is characterized by its excellent efficiency and compactness. Unlike other energy sources, geothermal power plants have a smaller physical footprint because most of the infrastructure runs underground. This space-saving feature makes geothermal energy an attractive option for areas with limited land space.

Geothermal energy has gained recognition for its high efficiency based on the pursuit of sustainability and economic efficiency. Geothermal power plants can produce two to four times more electricity than wind or solar plants of the same capacity. With its base load capacity and operational flexibility, this efficiency has led to mandates and incentives for utilities to invest in geothermal resources, ensure long-term grid stability and reduce costs.

Looking ahead, the potential of geothermal energy is far greater than that of power generation. As technological advances continue, geothermal applications will expand and provide solutions for heating and cooling needs in all 50 states. From urban environments to rural and remote communities, geothermal heat pumps and direct access systems offer options for sustainable and affordable heating and cooling solutions.

In addition, the widespread use of geothermal energy can significantly reduce emissions. By replacing fossil fuel-based heating and cooling systems with geothermal alternatives, significant progress can be made toward meeting climate goals and creating a cleaner, greener future.

The journey towards unlocking the full potential of geothermal energy requires continuous research, innovation and collaboration. The US Department of Energy, together with industry partners and stakeholders, is committed to promoting the development of Advanced Geothermal Systems and the widespread use of geothermal energy.

In an effort to heed Pope Francis’ call to be better stewards of our shared Earth to begin implementing the university’s new comprehensive sustainability strategy, Notre Dame has begun planning to install several geothermal systems across campus.

Geothermal systems use a network of buried underground water-filled pipes that maintain a constant 50°F year-round average temperature. Notre Dame’s systems work by circulating water through a system of closed-loop pipes about 300 feet deep before returning it to the surface and bringing it to the energy center. There, separate hot water and cold water streams are produced to supplement the energy needs of the existing heating and cooling systems, and the campus steam includes chilled water pipes.

The first phase of this project was completed this spring in the East Quad. A 300-ton geothermal energy field was installed in the grassy quad south of McCourtney Hall, east of Hesburgh Library, to more efficiently heat the cooling for the construction of the Ricci Ba Pasquerilla Center. A system of 153 wells will provide Ricci a Pasquerilla halls with a capacity of 150 tonnes, leaving an additional 150 tonnes for future development.

Geothermal Heat Pump: How It Works

The Seco phase was accomplished this summer with the installation of a geothermal well field under the parking lots south of Notre Dame Stadium. With about 500 wells with a capacity of 1,000 tons, this field is much larger than the Ricci/Pasquerella field. Unlike the East Quad system, which only provides cooling for certain buildings, the south campus system will also connect to the central campus chilled water system for future buildings in area a.

“Connecting our geothermal fields to both localized centralized systems allows the university to maximize energy efficiency,” said Paul Kempf, senior director of technical services. “If more chilled water is produced than local building needs, the excess water can be pumped into a central system for use elsewhere on campus.”

The third phase, currently under construction, will include the installation of approximately 650 wells with a capacity of 1,350 tons, which will become the new Ricci Athletic Fields on the north side of campus. This system will connect to a new remote chiller plant east of Wilson Drive. Connecting this geothermal site to the plant increases flexibility by allowing the site to serve a central chilled water cooling system and a new regional east campus hot water heating system.

When complete, these three systems will together have the potential to reduce Notre Dame’s carbon dioxide emissions by 11,803 tons, an 8 percent increase over fiscal year 2016, equivalent to taking nearly 1,000 cars off the road each year.

Geothermal Heating And Cooling Networks For Green And Livable Urban Transformations

In addition to these planned milestones, several areas of campus continue to be investigated for potential geothermal fields. White Field is being considered for a 2,300-ton well field that will expand to support future North Campus growth, Burke Golf Course is being considered for a 2,000-ton geothermal field that will expand to support the West and South Quads .

The combined capacity of all the proposed systems would be 7,000 tons, or half of the university’s current peak capacity during the cooling season.

“Because geothermal systems transfer heat from one place to another instead of burning fossil fuels like traditional boilers, they do not emit greenhouse gases. This will reduce pollution and improve air quality,” said Lia Kurtos, director of sustainability. “In addition, the indoor systems being installed at Notre Dame will not consume any water. The system is filled and water is pumped through the energy transfer well area; these systems improve the sustainability of the system and the campus as a whole.

Compared to other renewable energy sources, geothermal applications provide a positive return on investment, as installation costs are quickly recouped through energy cost savings. The estimated capital cost of the systems currently being installed on the Notre Dame campus is approximately $40 million. The university expects to pay back the investment in about 15 years.

Furthermore, the use of geothermal energy does not directly involve the burning of any fuel; instead, it uses electricity for a high-efficiency energy cycle, thereby limiting the impact of energy price fluctuations, allowing for the use of more sustainable sources of energy production to provide electricity, thereby increasing Notre Dame Energy’s financial security .

Notre Dame joins more than 100 colleges nationwide that currently use geothermal as a campus energy source. In fact, the nation’s largest closed-loop geothermal system to date is located in Notre Dame’s backyard at Ball State University, 140 miles south of Muncie, Indiana.

In addition to geothermal, the University is working with the City of South Bay to expand its renewable energy portfolio to include large-scale regeneration by installing a 2.25-megawatt hydroelectric project on the St. Joseph River, a heat recovery system. power plant to support the east campus as well
