Geothermal energy utilization -
Every year, Lazards shares a rather great overview on the levelized cost of energy LCOE , the most recent one can be found here.
One element that is a challenge to geothermal energy development in the U. is the long time it takes to get the necessary permits in place.
This — so the author — can take years and has been criticized by the industry for a rather long time with no real impact so far. Another challenge mentioned in the article is the poorly mapped resources in the U. A Geothermal Survey by the USGS, seems to have been the last larger scale approach to mapping the U.
geothermal resources, and — as many argue — missed the opportunity to evaluate low-temperature resources. Despite being more difficult to map, they could have shown a much wider opportunity for geothermal, and in the low-temperature context for heat exchange systems and deeper EGS resources.
The author argues that the assessment should be made much more frequently, similar to the efforts for oil and gas. The lacking lobbying power of geothermal is mentioned and clearly while previously the U.
Geothermal Energy Association, and now the Policy Committee of the Geothermal Rising association in the U. have been doing a great job, it does not provide the large and strong lobbying power of other industries, such as oil and gas.
The article then looks into the impact the American Recovery and Reinvestment Act of had, providing a great overview table highlighting a rather positive picture for geothermal.

The thermal energy storage properties of the rocks and soils allow GHPs to act as a heat sink —absorbing excess heat during summer, when surface temperatures are relatively higher—and as a heat source during the winter, when surface temperatures are lower.
This increases efficiency and reduces the energy consumption of heating and cooling for residential and commercial buildings. Learn more on our geothermal heat pumps page and in our fact sheet, What are Geothermal Heat Pumps? The presence of hot rocks, permeability, and fluid underground creates natural geothermal systems.
At the surface, that energy drives turbines and generates electricity. Sometimes conditions are not perfect for natural geothermal systems; the rocks are hot, but they are not very permeable and contain little water. The injection of fluid into the hot rocks enhances the size and connectivity of fluid pathways by reopening fractures.
Once created, an enhanced geothermal system EGS functions just as a natural geothermal system does. The fluids carry energy to the surface, driving turbines and generating electricity.
Learn about EGS , how it works , and its future in the United States. District and community-scale geothermal heating and cooling systems use one or more underground loops to create a heating and cooling network that can use a series of heat pumps.
New and different configurations of these systems are emerging in universities and communities all over the United States. Learn more about community geothermal systems and geothermal heating and cooling.
Exploring, discovering, developing, and managing geothermal resources is inherently complex and can have greater risks and upfront costs than other renewable energy technologies.
Geothermal can also face barriers in land access, permitting, and project financing. In addition, all geothermal resources share a key non-technical barrier: lack of awareness and acceptance.

Format: Paperback. There are five countries that belong to the GW club with a geothermal power generation capacity of 1, MW or more.
For an always up to date Top 10 Country List for geothermal power generation capacity, see our Research pages. Leave out for the moment as we will have to add it to the research pages when we are getting to that. The Top 10 list of countries with geothermal power generation capacity Status as of year-end , source ThinkGeoEnergy.
According to the Global Update for Power Generation for the World Geothermal Congress , the total electricity generated was 95, GWh for For geothermal direct use including ground-source heat pumps , the Global Update for Direct Use of Geothermal for the World Geothermal Congress reports that as of today 88 countries are currently utilising geothermal energy for direct use applications.
The estimated total installed thermal generation capacity is about , MW thermal. With an increasing interest, as well as attention to the heat sector for decarbonisation of the energy sector, it is maybe not surprising that this sector of the geothermal industry is expected to see exponential growth exceeding that of the geothermal power sector.
Top 10 Geothermal Countries Direct Use installed capacity The majority of countries generating electricity with geothermal today, are located in the hot regions of the world along the boundaries of tectonic plates, such as the Pacific Ring of Fire, often connected to volcanic activities.
These high-enthalpy regions represent the most economic way of tapping geothermal energy. The predominant example clearly is Turkey with an installed power generation capacity of around 1, MW as of August The plant is being updated on a regular basis. In the figure below you can see the share of geothermal power generation in the overall electricity market in selected countries, highlighting the often very important role not only in the overall electricity supply, but also in the contribution of electricity generated by a renewable energy source in those countries.
Depending on the resource quality, it can be said that no country in the world is fully tapping its available resource potential. Countries like Indonesia, Japan and the United States are only tapping a fraction of their resource potential. Indonesia alone has an estimated potential of up to 29, MW, yet has only used so far a geothermal power generation capacity of 2, MW.
In Japan the same applies. At the same time, geothermal resources of lower temperatures are likely a multiple of that for high temperature and for power generation. So here the opportunities are endless. Geothermal energy is being used for power generation by turbine-generator sets on the surface.
Traditional steam turbines either dry-steam or flash are utilising high temperature resources of degrees Celsius on the surface and more. The existing power plant technology uses the high temperature steam, either dry steam where available, or from steam water mixtures utilising flash technology.
Both are using the steam that turns a turbine which generates electricity. The average size of dry steam and flash-condensing geothermal power plants is around 53 MW. For resource temperatures between 70 degrees and up to around degrees Celsius, the use of a binary cycle technology turbine extends the opportunities of generating electricity from geothermal resource.
This technology — in very simple terms — utilises a secondary fluid that boils at lower temperatures, and the steam generated there then turns a turbine generating electricity. This technology clearly is a bit more complex and has been more expensive, while being quite competitive also for higher temperature resources today.
The average size for binary cycle geothermal plants is around 10 MW. At the same time, one can see a large number of new technology providers providing small binary-cycle power generation units with capacities such as 40 kW for very small units, as well as kW units.
The ranges though go all from 1 MW up to larger scale plants. The largest binary cycle geothermal plants have a capacity of 60 MW. The International Geothermal Association IGA defines geothermal direct use as utilising the energy of the earth geothermal heat directly as heat instead of indirect heat use for power generation.
Most direct use applications can be applied for geothermal fluids in the low to moderate temperature range 20 — °C. Low to medium temperature geothermal resources have been used for ages especially in a first time for bathing and later on for space heating and farming applications, as well as for cooling.
Today, geothermal is mostly used for heating baths and swimming pools, as well as for space and greenhouse heating. Other applications are industrial uses utilizing heat, aquaculture pond heating, agricultural drying, cooling and snow melting.
Particularly, the use of geothermal energy for heating of swimming pools and heating for buildings space heating has grown in recent years. Here a geographical overview over the heat production by year through geothermal direct use excluding heat pumps.
HVAC applications have been around for decades. HVAC stands for heating, ventilation and air conditioning. HVAC heat pumps are devices that are being used to warm, but also cool buildings by transferring thermal energy from the subsurface but also air and e.
lakes from either cooler or warmer space using a refrigeration cycle, similar to a normal household fridge. With electricity applied the performance of those heat pumps is then determined by a coefficient performance COP. The higher the COP is the more efficient the heat pump is and less energy it consumes.
So the higher the temperature in the ground is the less electricity it requires to expand thermal energy to higher temperatures for heating. Ground source heat pump also referred to as geothermal heat pump are transferring heat to or from the subsurface, thereby taking advantage of the constant temperature of the earth throughout the seasons.
The heat pump as such is connected to a geothermal exchange set-up, which can be engineered using a closed-loop vertical or horizontal exchange, direct exchange, piles, utilising a loop in a pond, lake or the ocean, standing column wells or well doublets.
They all have in common that the refrigerant is run through those pipes used to transfer the heat picked up from the subsurface to the heat pump. In the winter-time, the heat pump can use the thermal energy picked up to heat a building or buildings in larger settings , or in the summer for cooling a building.
