[6] CLG can provide cost-effective electric power and thermal energy for very pure hydrogen production by electrolysis. The technology of utilizing a low-temperature water is more expensive than the traditional steam technology used in the large geothermal power plants. Apply Online. The price of a home geothermal heating/cooling system varies, largely depending on the size and type of loop system needed. If it is a small power plant (<1Mwe), the cost is probably around $3000-$5000/ kWe. One Small Tax Credit for Geothermal Power, One Giant Leap for Binary Power Plant: Uses geothermal water (120 - 180C) and a second (binary) liquid that boils at a lower temperature to spin turbines. Geothermal power plants are not new to Japan. The initial cost of small-scale geothermal power plants is higher than for larger geothermal power plants. The Cost of Geothermal Energy | Earth and Human The first cost of a small geothermal power plant is normally distributed with a mean of $150,000 and a standard deviation of $50,000. . Operating and maintenance costs range from $0.01 to $0.03 per kWh. The ORC technology is particularly suitable for the exploitation of medium-to-low enthalpy sources. It is used even today, as it is very environment-friendly. The interest rate for evaluation is 8%. (The basis of this cost estimate for small geothermal plants is described in Box A in Section 2-3.)
