WHAT IS GEOTHERMAL ENERGY?
The word Geothermal is derived from two Greek words “Geo” which means ‘Earth’ and “Thermo” which means ‘Heat’. Thus, geothermal energy is the internal heat of the earth. It is a clean and sustainable source of energy. The geothermal resources are found in the ranges from low-to-high enthalpy resources. They are manifested on the surface in three forms hot springs, fumaroles and geysers.The amount of heat within 10,000 meters of earth’s surface is 50,000 times more energy than all the oil and natural gas resources in the world.
Geothermal energy is being used for direct as well as indirect uses for domestic, commercial and industrial purpose. The countries like Iceland, Indonesia,Mexico, Philippines, New Zealand, Iceland, California (US) are highly active in the field of exploration and exploitation of Geothermal energy. However, in India, the potential Geothermal Energy has not yet been tapped. Puga Valley (Jammu and Kashmir), Tatapani (Chhattisgarh), Chamoli (Uttarakhand), and Bakreshwar (West Bengal) have been looked upon as the potential geothermal reservoirs till date. But, as per the studies conducted by Geological Survey of India (GSI), Gujarat also has a potential of geothermal energy, which is yet to be explored.
In order to put Gujarat on unconventional energy basket in India, GoG took an initiative of establishing a centre dedicated to research & development activities in the area of exploration and exploitation of geothermal energy. In this light, with the support of GoG, PDEU established Centre of Excellence for Geothermal Energy (CEGE) on 10th of October, 2013. For smooth functioning of the centre, PDEU faculties took a lead and started developmental activities for the centre. With time, research professionals were also inducted into the centre in order to fulfil the aspirations of GoG as well as the centre.

Geothermal Energy : Indian Scenario
Geothermal energy exploration in India has long history. However, an extensive literature survey depicts that the efforts across India is not systematic. Remote sensing, Seismic, Gravity-Magnetic Survey, Electrical Resistivity and Magnetotelluric Surveys are the techniques normally used for exploration activity. Promising areas are identified in Himalayan area, Puga, Manikaran, Chhumatang, Beas and Satlej field, Chamoli, Western India. There have been efforts made by various organizations in exploration of this clean energy. Organizations likes NGRI and GSI are the leading forces behind such explorations for over four decades. However, no exploitation for domestic and commercial uses is known to the authors of this paper. Bore well drilling, identification of hot water source and measuring temperature gradient are the parameters considered by most of the researchers.

RESEARCH ACTIVITIES IN CEGE
GSI has identified seventeen active hot springs in Gujarat region. After a review of this data, Government of Gujarat (GoG) directed PDEU, through Gujarat Power Corporation Limited (GPCL), to conduct research and development activities on geothermal potential at these seventeen identified sites. Prefeasibility studies were conducted by PDEU, primarily through remote sensing and landsat imageries to narrow down on the potential study areas. Six sites were identified for conducting further investigation on geothermal resource potential, namely Dholera, Unai, Gandhar, Tuwa, Chabsar and Tulsishyam which are shown in the map below.
CEGE is carrying out exhaustive research in the investigative studies for analysing the resource potential of the above mentioned sites. CEGE has concentrated on three sites namely, Dholera, Gandhar and Unai for further investigation. Two sites i.e. Chabsar and Tuwa are being investigated upon by Institute of Seismological Research (ISR), Gandhinagar. Tulsishyam being a wild life area, was not considered for further studies.
CEGE has used techniques such as Geochemical studies, Magnetotelluric (MT) survey, and Gravity survey to identify the location of geothermal reserves in the study areas. 2D Magnetotelluric survey was carried out with the help of M/s PBG Geophysical Exploration Ltd., Poland at all the three locations (Unai, Gandhar and Dholera). The acquisition, processing and interpretation of MT data have depicted the subsurface picture reasonably well.
Solar Geothermal Hybridization:
Hybridization is an efficient, cost effective and environmentally conscious decision. Both geothermal and solar have high potential in similar geographical area and make up for each other`s disadvantages. This also accentuate the thermal efficiency of the renewable energy with very less operating expenditure and simple machinery.
a. Parabolic Trough Collector (PTC)
d. ADVANTAGES OF PTC
- Efficiency increase. Present target increase of 30 ºC may be expected.
- Efficient energy production.

- Stand-alone geothermal efficiency is around 21% whereas Hybrid geothermal efficiency with solar is around 50%.
e. PROPSED DESIGN ASPECTS
- One parabolic trough will generate 0.8133 KW/ hr
- With help of four troughs 20 KW of electricity will be generated 6 hrs/day
- Industry : Acclaim technology services India private ltd.
- Cost of one trough : 40,000 - 50,000/-
3D Magnetotelluric Survey:
Based on 2D MT results, CEGE carried out 3D MT survey at Unai. 3D Magnetotelluric (MT) Survey has been done first time in India at Unai.
Drilling of Bore well:
On the basis of the results obtained from exploration surveys two wells A01 and A02 are drilled in Dholera Swaminarayan Temple up to the depth of the 1000 ft. The hot water is gushing out of the mother earth with the flow rate of about 5 to 6 lit/sec and temperature is 45oC. The subsurface temperature gradient is 3.5oC/100m.
Space Heating and Cooling System at Dholera, Gujarat:
Geothermal Space Heating and Cooling system at Dholera is based on Ground Source Heat Pump (GSHP) instrument, a first of its kind in India. Centre of Excellence for Geothermal Energy (CEGE), Pandit Deendayal Energy University (PDEU) have developed this system in association with Green India Building System and Services (GIBSS).
This system has been implemented at Dholera geothermal site, located in the Ahmedabad district in the Swaminarayan Temple. Based on various exploration techniques, two geothermal bore wells were drilled at Dholera on October 28, 2015 and January 31, 2016 respectively of 1000 feet depth. The temperature of the water is 47 to 50 degree Celsius, with a flow rate of seven to eight litters per second. The water is produced from the well without any external energy.
Geothermal Heat Pump or Ground Source Heat pump is one such method, which can be used to utilize the energy from the low enthalpy reservoir. The geothermal space heating and cooling system consists of heat exchanging device at both condenser and evaporator side of the Ground Source Heat Pump (GSHP). The heat pump is a device, which is designed in such a way that it provides heating and cooling system simultaneously using geothermal energy as a source. The heat pump consists of four components namely evaporator, condenser, compressor and expansion valve. Evaporator (cooling side) of the heat pump is utilized for comfort cooling to assembly Hall at the temple. The output from Condenser (heating side) of the heat pump will be utilized as an input to Organic Rankine Cycle (ORC) for power generation at pilot scale. The system is producing cooling of 32 TR capacities at the Sabhamandap (Assembly Hall) of the temple as an additional benefit. The heat pump system is highly energy efficient and eco-friendly system with minimum usage of water and optimum requirement of electricity.
The geothermal space heating and cooling system will help in replacing conventional air conditioning systems, water cooling systems and water heating systems in highly energy efficient manner. In this system, the consumption of electricity is reduced and financial benefits can be achieved in the long run. The capital expenditure of such systems is high, however, due to lesser operational expenditure; it will be commercially beneficial in the long run. The payback period varies based on the size of the system, applicability, usage and ambient atmosphere. Additionally, the system being a closed loop system, huge amounts of water will be saved. The system doesn't emit any kind of greenhouse gases as well.
The hot water produced from the system can also be utilized in some of the other direct applications such as green houses, ice melting, fish farming, crop drying, capsicum and tomato cultivation and spa/domestic purposes, whereas the cold water produced can be utilized in cold storages and process cooling in commercial and industrial applications.
|Benefits of the system:
Reduced water consumption
Reduced carbon dioxide emission
Reduced carbon footprints
20 to 50% Energy Savings
100% water savings
No chemical usage

Organic Rankine Cycle: Power generation:
The Organic Rankine Cycle (ORC) system involves the same component as in a conventional steam power plant i.e. a boiler (heat exchanger/evaporator), a work producing expansion device (turbine), a condenser (cooling towers) and a feed pump.
Schematic of an Organic Rankine Cycle
After successful commissioning of the Geothermal Space Heating and Cooling plant at Dholera, CEGE is focussing on pilot scale electricity using Organic Rankine Cycle (ORC). The Geothermal Space Heating and Cooling system based on Ground Source Heat Pump (GSHP) system will be integrated with the ORC system in a unique way. The output of the GSHP system will be used as the input for the ORC system. The geothermal power generated through the ORC system will be first of its kind in India. After the successful project on a pilot scale, the system can be replicated on a commercial level.
ORC systems are used for power generation from water flowing at low temperature. The ORC system uses an organic fluid with low boiling point than that of water. The minimum required temperature of the flowing water is 77 to 80 degree Celsius. The GSHP system is designed in such a way that the output of the heating side of the system is 80 degree Celsius. This output will be used as an input to the ORC.
Geothermal Energy for Societal Benefits:
Apart from power generation, CEGE is exploring the possibilities of utilising the low enthalpy geothermal water for various direct applications.
In India, the geothermal fields are of low enthalpy in nature compared to other part of the world. However, the direct applications of geothermal can be taken into consideration for low enthalpy geothermal fields in India, as these applications require relatively low temperature to function. Some of the direct applications are milk pasteurisation, fish farming, crop drying, green house, agriculture, sericulture, and balneology. If the shallow geothermal well at Unai is successful, the hot water generated from the well will be utilised for different direct applications based on the local conditions.
CEGE is planning to drill 1000 ft. Deep bore well in Unai geothermal field. The well parameters will be similar to Dholera geothermal wells A01 and A02. The drilling activity will be carried out at the best possible location identified based on the results of 2D and 3D magnetotelluric survey, gravity survey, remote sensing and geochemical analysis. If the geothermal well is successful, the hot water produced from the well will be utilised for direct applications of geothermal energy.
The Unai field is surrounded by rural areas with the population largely dependent on agriculture and cattle-rearing. Additionally, Unai site is located in vicinity of a dense forest area with different varieties of vegetation and cultivated land. Hence, in this region, applications related to agriculture, green houses and animal husbandry can be implemented in the area.
Balneology- From centuries the geothermal water is used for bathing and treatment of skin dieses.The systems like steam bathing and spas are also utilising the geothermal energy for providing heat and steam. These types of system also lead to some of the health benefits like improvement in blood circulation, in cleaning and skin rejuvenation, relief in muscle tension and enhancing detoxification processes.In Dholera a bathing kund is formed in Swaminarayan temple where people from nearby villages use it for bathing and domestic purposes.
Honey Processing- CEGE has formed an integrated extractor- processor assembly for honey processing using geothermal water. The following steps were performed during processing.
Milk Pasteurization- CEGE is planning to set up a milk pasteurization plant at Dholera.As there is no milk pasteurization plant near Dholera people of Dholera and nearby villages can use benefits of this plant.Milk pasteurization plant will use the discharged water from Space Heating and Cooling plant.Designing of milk pasteurization plant is under process in Dholera where the residual water of 80oC is used.
Food Dryer Article:
Geothermal energy is initiating in India, with several explorations and exploitation. This energy was formed around 4 billion years ago due to the fusion process. Around 155 million tons of food products are produced in India. To overcome the grain losses due to storing and harvesting a food drying system can be made for the preservation of crops. In India, around 60-80% of farmers use a sun-dry method which is not an appropriate way for grain drying, which leads to loss of needful minerals or vitamins for the human body. CEGE is working in direct application sectors of geothermal energy. After honey processing & balneology, CEGE is going to set up a food dryer in Unai.
The system works in 3 stages: 1) In the initial stage, the geothermal water is pumped and stored in the tank, 2) in the next stage, the geothermal water is circulated to a heat exchanger where the heat gets exchanged with the heat pump. 3) And in the final stage, the heat from the heat pump is passed into the chamber for drying food products that are placed on the stainless steel trays.
