How about geothermal?

Wednesday March 8, 2017

Why not geothermal energy on the grid for power in the Yukon? Scientific studies say the Tintina trench, near Ross River, is the hottest geothermal deposit in Canada. There is a possibility that 1700 MW of energy could be put on the grid which would help power proposed mines, railways etc.

There are geothermal plants on the grid all around the world, but none in Canada. There is lots of information indicating that developing geothermal energy is cheaper than other alternatives. It is a tax credit industry and can create many jobs like 24-hour greenhouses making food year round and even melt the snow on our roads.

Bruce Williams have you any idea of what you are talking about?
How do you want to add 1700MW to the YEC capacity of about 100MW?
Do you have any idea what it would cost to drill 4000m to 5000m maybe even more and then put a Steam Turbine Generator plant on top of it?
Plus resizing the whole distribution grid.

Geothermal is not feasible for the small population and the fast distribution grid for Yukon.

What is feasible is ground source heat with heat pumps. I think this is what most people mean when they say geothermal but that term is miss used.
But to make it feasible we need smaller drill rigs in Yukon who do drill only 2” holes to a depth of 15m to 30m
for the cost of $20 to $30 a foot. This would be maybe double the cost of installing a heating fuel tank.
An antifreeze solution in 1/2” tubing would be circulated through these holes and back to the heat pump. Where the extracted heat from the earth would be increased to a temperature to heat a building.
Heat pumps coast these days between $3000 and $6000 depending on size of a residential building or could be installed in series for larger buildings.
The electric energy consumption rating is 1to3 to 1to10, where 1 is the energy input and the other number the energy extracted.
The electricity used could come from solar and wind in combination with batteries. The heat pumps should be connected to storage tanks too, so no problems to overcome times where there is no solar or wind.
This would be job creation for drillers laid of from the O&G industry. Jobs for local plumbers and electricians.

Much more economical and feasible then geothermal.
