Grey Rock Investment Partners is a private equity firm with more than $1.3 billion in assets under management. The firm invests across the energy value chain including carbon capture, industrial electrification, power optimization and natural resources. In May 2022, Grey Rock agreed to fund additional growth of Vault through a capital commitment of up to USD$150 million. Matt Miller, Co-Founder and Managing Director at Grey Rock stated “We find carbon capture and sequestration to be one of the most compelling opportunities in the energy transition. After having met with several CCS teams, it was clear to us that Vault was the right fit for us in how we approach investments”.
Currently, Vault has developed an extensive platform of actionable CCS projects with ethanol facilities in the Midwest region each of which emits between 200,000 and 500,000 tonnes of CO2 per year. In addition, Vault is involved in several high quality, early-stage CCS projects in Canada such as the Hinton Bioenergy Carbon Capture and Storage Project in collaboration with West Fraser and Torchlight. Vault’s pipeline spans a range of industrial sectors including power generation, cement and lime, forest products and hydrogen production that spans multiple regions of North America.
