Greenhouse Canada
Summary
As greenhouse producers look towards a net zero carbon future, alternatives to fossil fuels start to look increasingly attractive, and geothermal is one of them.
But there’s still confusion around the terminology. Vice-president of Geothermal Canada and president of the geothermal power project, Alberta No. 1, geologist Catherine Hickson, PhD, says it has been and continues to be one of the biggest problems she’s faced in the sector over her 40-year career. Unbeknownst to many, the term “geothermal energy” actually points to a range of technologies, each with differing capabilities and costs.
In B.C., the Tu Deh-Kah Geothermal project, aims to provide seven to 15 megawatts of power. Previously known as the Clarke Lake Project, this initiative is led by the Fort Nelson First Nation community. Similar to the other two projects, there is a keen interest in using the waste heat for other purposes including increasing the region’s food security and potential for agricultural exports.
“We have to be big, in order to be cost effective. That’s why district heating, hectares of greenhouses – that scale of project is what we can do in deep conventional geothermal,” says Hickson.
