Pipelines

The original pipe is 60+ years old, my guess is they are going to slowly replace the pipe in section as a "repair" and not "New pipe", which causes more permit and social unrest headache.
 
I’d say this is good news but I’m waiting to be told by others why it’s not.

Thermal storage of electrical energy using molten salt. I liken the concept to a form of renewable geothermal energy.



Rather than trying to balance the grid second by second as windmills and solar panels come on and off line and then trying to connect all those individual generators to the grid the concept would be to use the electricity when it is available to pump energy into the ground or, in this case, into a tank of salt. The salt becomes molten and the heat is stored as a liquid at 600C.

That heat can then be used to operate a conventional steam turbine plant to produce electricity with variable loads on demand. It can also be used to heat urban districts.

In an Alberta context two options present themselves.

Given the farflung nature of the windfarms then one option would be to add a salt battery to every farm and pump the heat into the battery whenever the wind blows. If you installed a steam (or ammonia) based generating system on the same site then the grid could draw on the energy when the demand arose.

The other option would be to locate the salt batteries and generating plants in town and use dedicated power lines from the wind farms to keep the batteries fed. The lines would be separate from the grid.

'Systems Thinking' enters the chat ;)

 
Posting here as the ‘best fit’ thread: British Columbia approves eight year extension and expansion of an open pit copper and gold mine; determines that reasonable and meaningful consultations don’t necessarily have to reach consent or consensus.


Can I recommend that this thread be expanded a bit (maybe reflected in the title) to be come a catch-all for natural resources development in Canada and associated infrastructure? I suspect we’ll have an increase in discussion on this subject and a thematic thread will probably suit it well.

The use of salt makes me also wonder if some of the subsurface formations...some of which are full of saltwater...could be used. There are also empty formations being used as disposal wells and some of the pipelines currently in the country are used for pumping this fluid to a selected disposal well (subsurface formation).

Two benefits of this...one the re-introduction of fluid helps stabilize rock formations to reduce earthquakes. A lesson learned from the the 1970's and 1980's Colorado drilling fields. Second it may allow for a concentration of salt/water that even if heated should remain within the formation at a heated gaseous state similar to natural gas capture?

Not a geologist or driller but does make me wonder about opportunities not just here but also places like southern Ontario (former Windsor Salt mines) or a ocean water test along the ocean coasts.

My fascination has been similar. There are a lot of abandoned unproductive and dry wells. Could those be converted into heat sinks to support steam plants? And could the electrical supply from the wind and solar farms be simplified as unregulated DC? Any heat is good heat.

Wind is for wankers ;)

Geothermal energy in Canada​

Canada has vast geothermal energy resources that could be used as clean sources of power, relying primarily on binary cycle power plants to generate geothermal energy. The potential for geothermal development is distributed throughout Canada, but more data is required for much of Canada’s land. The highest temperature geothermal resources are located in British Columbia, Northwest Territories, Yukon, and Alberta. Further research and mapping are required to reduce exploration risk and support regulatory development.

Presently, several heat and power generation projects are being developed with support from Natural Resources Canada. Through the Emerging Renewable Power Program (ERPP), Natural Resources Canada have invested to help de-risk early stage development and to advance a small number of geothermal projects. Additionally, the Smart Renewables and Electrification Pathways (SREPs) Capacity Building Program provided funding for pre-development activities, including geothermal development in Canada.
