Alberta’s oil sands produce some of the most responsible energy in the world and have drastically reduced the amount of fresh water used per barrel. Yet, for decades, operators have been forced to store most of the water they use on site, leading to billions of litres now contained largely in tailings ponds.
Alberta is investing $50 million from the industry-funded TIER system to help develop new and improved technologies that make cleaning up oil sands mine water safer and more effective. Led by Emissions Reduction Alberta, the new Tailings Technology Challenge will help speed up work to safely reclaim the water in oil sands tailing ponds and eventually return the land for use by future generations.
“Alberta’s government is taking action by funding technologies that make treating oil sands water faster, effective and affordable. We look forward to seeing the innovative solutions that come out of this funding challenge, and once again demonstrate Alberta’s global reputation for sustainable energy development and environmental stewardship,” said Rebecca Schulz, Minister of Environment and Protected Areas.
“Tailings and mine water management remain among the most significant challenges facing Alberta’s energy sector. Through this challenge, we’re demonstrating our commitment to funding solutions that make water treatment and tailings remediation more affordable, scalable and effective,” said Justin Riemer, CEO, Emissions Reduction Alberta.
As in other mines, the oil sands processing creates leftover water called tailings that need to be properly managed. Recently, Alberta’s Oil Sands Mine Water Steering Committee brought together industry, academics and Indigenous leaders to identify the best path forward to safely address mine water and reclaim land.
This new funding competition will support both new and improved technologies to help oil sands companies minimize freshwater use, promote responsible ways to manage mine water and reclaim mine sites. Using technology for better on-site treatment will help improve safety, reduce future clean up costs and environmental risks, and speed up the process of safely addressing mine water and restoring sites so they are ready for future use.
“Innovation has always played an instrumental role in the oil sands and continues to be an area of focus. Oil sands companies are collaborating and investing to advance environmental technologies, including many focused on mine water and tailings management. We’re excited to see this initiative, as announced today, seeking to explore technology development in an area that’s important to all Albertans,” said Kendall Dilling, president, Pathways Alliance.
