Why Is Geothermal Energy Good For The Environment – Geothermal energy is all energy stored as heat beneath the surface of the solid earth. It is a reliable and permanent source of renewable heat that is low carbon and weather independent. It is found across the UK at depths ranging from a few meters to several kilometers and can be mined using different technologies.

Heating accounts for around a third of the UK’s total energy use (latest figures for 2021). More than 80% of domestic heating is still provided by gas boilers, but it accounts for almost 17% of the UK’s carbon emissions. In order to achieve net zero targets in the UK by 2050 (and in Scotland by 2045), carbon emissions will need to be drastically reduced. This will require a rapid transition from fossil fuels to low-carbon energy. Geothermal energy is an important alternative to decarbonising heat and power and can make an important contribution to achieving net zero targets in the UK. by heating the low-carbon space.

Why Is Geothermal Energy Good For The Environment

Geothermal energy is a local source of energy that is always available (unlike wind and solar, regardless of weather conditions). It takes up very little space and is expandable, that is, it can be used as a central heating source in addition to heating the apartment. Geothermal energy is also a key asset for energy security and independence from gas imports. However, the UK currently uses only a small fraction of its geothermal resources and there is significant scope to increase its contribution to the energy mix.

The current priority is to provide national-scale geothermal data sets, maps and products in line with the 2023-2028 strategy. This includes collecting old data, new data and resource mapping.

We work with government, academia, and industry to improve subsurface properties, assess geothermal resources, and develop the geoscientific knowledge needed to sustainably exploit them. Our team contributes to a wide range of projects, from resource feasibility characterization to monitoring and modeling changes associated with geothermal exploitation.

In addition, research and innovation infrastructure such as the UK’s Geoenergy Observatory enables extensive research to improve our understanding of how geothermal energy can contribute to reducing carbon emissions.

Geothermal energy is available in a variety of geological settings across the UK. It can be used to generate thermal (and in some places electrical) energy for a wide range of applications.

Imagine a home where the temperature is always comfortable, but the heating and cooling systems are invisible. This system works efficiently but does not require a lot of maintenance and knowledge from the owners.

The air smells fresh; you can hear birds chirping and the wind rustling lazily through the trees. Just as the roots of a tree exchange the essentials of life with its leaves and branches, the home shares energy with the earth. Sounds comfortable, right?

Geothermal heating and cooling make this vision a reality. Geothermal HVAC (Heating, Ventilation, and Air Conditioning) takes advantage of underground temperatures for heating in the winter and cooling in the summer to bring buildings into contact with the soil.

Outside temperatures change with the seasons, but thanks to the Earth’s insulating properties, underground temperatures don’t change much. Temperatures 4 to 6 feet below ground remain relatively constant throughout the year. A geothermal system, consisting of a system of buried pipes and an internal regulating device called an underground loop and/or injection pump to a re-injection well, supplies these constant temperatures with “free” energy.

(Note that geothermal HVAC is not to be confused with “geothermal energy”, which is the process of generating electricity directly from the heat inside the earth. This is done within a utility and usually uses a variety of processes by heating water to a boiling point. . )

The pipes that make up the earth loop are usually made of polyethylene, which can be buried horizontally or vertically underground, depending on the characteristics of the site. If an aquifer is present, engineers may prefer to design an “open-loop” system in which wells are drilled into the groundwater. The water is pumped out, forced past the heat exchanger, and then “re-injected” to return the water to the same aquifer.

Solar Vs Geothermal Energy: Which Is Right For You?

In winter, the fluid circulating through the system’s ground loop or well absorbs heat stored in the ground and transports it inside. An indoor unit pumps the heat to a higher temperature and distributes it throughout the house like an air conditioner in reverse. In the summer, a geothermal HVAC system draws heat from the building and passes it through a ground loop/pump to a re-injection well, where the heat is stored in the cool ground/aquifer.

Unlike conventional heating and cooling systems, geothermal HVAC systems do not burn fossil fuels to generate heat; they simply transfer heat to and from the Earth. In general, electricity is used only to run the equipment’s fans, compressors, and pumps.

Geothermal cooling and heating systems have three main components: a heat pump device, a liquid heat exchanger (open or closed loop), an air transfer system (ducts) and / or radiant heating (floor or elsewhere).

Geothermal heat pumps and all other types of heat pumps have an efficiency that is rated according to the coefficient of performance or COP. It is a scientific method of determining how much energy a system is moving and how much it is expending. Most geothermal heat pump systems have a COP of 3.0-5.0. This means that for every unit of energy used to power the system, three to five units of heat are provided.

Geothermal systems require little maintenance. When properly installed, a buried loop can last for generations. Because the unit’s fans, compressors, and pumps are housed indoors protected from harsh weather conditions, they last for years, often decades. Typically, periodic inspections, filter changes, and annual coil cleaning are the only maintenance required.

They fight with nature, not against it, and do not emit greenhouse gases. (As mentioned earlier, they use less electricity to operate because they are tied to the global average temperature.)

As part of the growing green building movement, geothermal HVAC systems are becoming a common feature of eco-friendly homes. Green projects accounted for 20 percent of all new homes built in the United States last year. By 2016, green housing will grow from $36 billion to $114 billion a year, according to a Wall Street Journal article. This is close to 30-40 percent of the total housing market.

But much of the information about geothermal heating and cooling is based on outdated information or outright myth. In our new book, Modern Geothermal HVAC Engineering and Control Applications (Egg/Cunniff/Orio -McGraw-Hill 2013), co-authors Greg Cunniff, Carl Orio, and I debunk many of these myths.

Advantages Of Geothermal Energy • Ingrams Water & Air

Fact: A geothermal HVAC system uses only one unit of electricity to transfer up to five units of cooling or heating from the earth to a building.

Fact: Geothermal HVAC systems consume 4 times more kilowatt-hours than photovoltaics and wind power added to the electric power grid. These other technologies can certainly play a role, but geothermal HVAC is the most effective way to reduce the environmental impact of air conditioning spaces.

3. Geothermal ventilation systems require a lot of space or real estate to accommodate underground polyethylene piping loops.

Fact: Depending on the nature of the site, the ground loop can be buried vertically, which means that it needs to be slightly above ground. Or if there is
