Geoscience BC Releases Comprehensive Guide for BC Communities on Development of Direct-Use Geothermal

VANCOUVER, BC--(Marketwired - June 27, 2016) - Geoscience BC today released its Direct-Use Geothermal Roadmap, a comprehensive guide for communities and businesses to help them evaluate and develop local geothermal energy projects to stimulate economic development and reduce greenhouse gas emissions.

"Direct-use geothermal energy resources are significantly underutilized in BC," said Carlos Salas, Vice President, Energy, at Geoscience BC. "From this study we found there was a considerable lack of understanding at the community level about the range of direct-use geothermal applications and the necessary steps required to develop local geothermal resources. The Direct-Use Geothermal Roadmap provides useful information needed by communities to assist them in evaluating, planning and pursuing geothermal projects."

The Direct-Use Geothermal Roadmap contains practical guidelines for communities on geothermal surface exploration, land acquisition and permitting, drilling and testing wells required for the design and development of direct-use geothermal resources in BC. The summary report and digital data are available here: Geoscience BC Report 2016-07: Direct-Use Geothermal Resources in British Columbia.

To support the release of the Roadmap, Geoscience BC is planning a series of community workshops facilitated by lead researcher Dr. Catherine Hickson, Principal of Tuya Terra Geo Corp. The first of these workshops will be a presentation to the BC Union of Municipalities in September. This presentation will be followed by regional workshops which will provide information and tools on how communities move forward with direct-use geothermal projects, addressing technical and non-technical aspects of development.

Direct-use geothermal energy uses thermal waters with temperatures generally less than 80 degrees C. Traditional uses of these warm waters have been for space heating and spa applications. Direct-use water temperatures and flow rates are considered too low to economically generate electricity. Potential direct-use geothermal energy applications include commercial, industrial and residential space heating, aquaculture, greenhouses, crop drying, snow-melting and recreational applications. Although BC has significant potential, direct-use geothermal is currently only used for recreational and therapeutic purposes such as hot springs.

A total of 63 communities were identified as being located close to the 18 regions deemed favourable for direct-use geothermal. This list of localities was subsequently narrowed down to 11 regions and communities which researchers deemed to have the best potential for direct-use geothermal development in BC. Additional development information was compiled for these regions and communities. These areas were ranked based on favourability for direct-use from various input metrics such as: proximity to infrastructure, the regulatory environment, environmental impact, and community receptiveness, among other factors. Sites with the highest weighted ranking included: Clarke Lake south of Fort Nelson, Sloquet Creek, 93 km northwest of Whistler, Lakelse Lake between Terrace and Kitimat, Canoe Creek - Valemount in the Cariboo, Jedney Creek north of Fort St. John, Meager Creek/Pebble Creek north of Whistler, Okanagan, Kootenay area, Lower Arrow Lake near Castlegar, Mt. Cayley, 45 km north of Squamish, and Mt. Garibaldi, 80 km north of Vancouver near Squamish.

"The real value of this study was the community outreach which took place," stated Dr. Catherine Hickson. "Through this study, we were able to identify critical knowledge gaps holding communities back from developing their geothermal resources. In many cases, direct-use geothermal had not even been considered in the community planning process. This Direct-Use Geothermal Roadmap will help fill those knowledge gaps and play an integral role in helping BC communities evaluate and pursue viable geothermal projects with the most promising economic potential."
