Montem Resources (ASX: MR1) has engaged multinational company Hatch to perform detailed engineering and design work for the Class III cost estimate for the Pumped Hydroelectric Energy Storage (PHES) element of its Tent Mountain Renewable Energy Complex (TM-REX) in Canada.
The work will contribute to planning for the transition of the former Tent Mountain coal mine following independent studies which demonstrated the strong viability of the project to accommodate a renewable energy development including 320 megawatts of PHES, an electrolyser 100 MW green hydrogen plant and a 100 MW off-site wind farm.
Hatch’s Class III cost estimate will be combined with project economics provided by Boost Energy Ventures.
Both sets of data are expected by mid-year and will provide Montem with the information needed to accelerate the development of TM-REX.
Montem Managing Director and CEO Peter Doyle welcomed Hatch to the project team.
“Hatch is a world leader in the planning and construction of pumped hydroelectric storage projects and [our] initial engagements have been very positive,” he said.
“The TM-REX continues its momentum and represents an extraordinary opportunity for [us] be at the forefront of Alberta’s energy transition.
Tent Mountain is currently a coking coal mine and late approvals for a restart led Montem to consider other options for development.
The transition to a renewable energy complex was announced in October, targeting the production of around 300 gigawatt hours of peak electricity per year from PHES.
On-site hydrogen production will transform Montem into the first large-scale green hydrogen producer in Canada, with production of up to 13,000 tonnes per year.
The Hatch contract is seen as a key step in de-risking the project and moving to commercialization.
The progress of the project
Doyle said progress on TM-REX continues, with the company recently submitting an application for grid connection to the Alberta Electric System Operator (AESO).
The submission is a key milestone in the project, which triggers the AESO’s staged validation process to secure interconnection capacity to Alberta’s transmission system.
Tent Mountain’s PHES is located a short distance from the high-voltage power grid, providing logistical and economic advantages.
Montem continues to work closely with Piikani Nation landowners on wind power generation strategies.
The Tent Mountain development is located on traditional Piikani territory, and Piikani reservation lands lie in the heart of southern Alberta’s wind power region.
Green Hydrogen Electrolyzer
Global mining consultant GHD is progressing a Class IV cost estimate to provide project economics for the TM-REX green hydrogen electrolyser element.
GHD will complete the preliminary engineering design and undertake an initial assessment of the land, water and regulatory requirements for the project.
It will also prepare the technical requirements for the production, storage and transport of hydrogen, and establish an optimal project delivery schedule.
Mr. Doyle said the work would help Montem explore the anticipated needs of a growing market as well as end users of green hydrogen.
