EnerPure Raises $35M to Build First Commercial Plant Converting Used Motor Oil Into Marine Fuel

Canada Growth Fund and Rice Investment Group have led a $35 million growth equity financing for EnerPure, a Calgary-based cleantech company developing modular recycling technology that converts used motor oil into low-sulphur marine fuels. Canada Growth Fund is investing $20 million, with Rice Investment Group contributing $15 million. The funding will support construction of EnerPure's first commercial-scale recycling facility in Alberta, with operations targeted for 2028, following successful pilot-scale demonstration in Manitoba.

 

Why Used Motor Oil Recycling Has Historically Been Underserved

 

Used motor oil represents a persistent waste stream that traditional re-refining infrastructure has struggled to process economically at smaller, regional volumes, since conventional re-refining facilities typically require large, centralised operations to achieve the scale needed for cost-effective processing. That structural gap leaves significant volumes of used motor oil in regions without access to large-scale re-refining facilities either underprocessed or handled through less optimal disposal or processing routes.

EnerPure's small-scale, modular recycling process is specifically designed to address that gap, aiming to build a network of regional recycling facilities capable of economically processing used motor oil volumes that traditional, larger-scale re-refining infrastructure has not adequately served. That modular approach differs from the centralised model dominating conventional oil re-refining, instead distributing smaller processing facilities closer to where used motor oil is actually generated regionally, potentially reducing transportation costs and expanding the total volume of waste oil that can be economically captured and converted rather than left underserved by existing infrastructure.

Why IMO 2020 Compliance Defines the Specific Market This Technology Targets

 

EnerPure's process converts used motor oil into fuel compliant with International Maritime Organization 2020 standards, the regulation that significantly tightened sulphur content limits for marine fuels used in international shipping. That regulatory framework created substantial demand for lower-sulphur marine fuel alternatives across the global shipping industry, since vessels operating internationally must now use fuel meeting these stricter sulphur limits or install exhaust scrubber systems to continue using higher-sulphur fuel.

By producing a drop-in fuel compatible with existing marine vessel engines rather than requiring engine modifications or new vessel designs, EnerPure's technology offers shipping operators a way to meet IMO 2020 compliance requirements without the capital expenditure of retrofitting vessels or purchasing new compliant engines, a distinction that matters considerably for the fuel's commercial viability within an industry where vessel retrofits carry substantial cost and operational disruption.

What the Investor Composition Reveals About the Deal's Strategic Framing

 

Canada Growth Fund's involvement reflects its stated mandate to catalyse private investment into Canadian clean economy technologies using instruments designed to absorb specific risks that might otherwise deter purely private capital from investing at this stage of a company's development. CGF chief executive Yannick Beaudoin specifically framed the investment as supporting "the commercialization of a Canadian-developed circular-economy solution in a hard-to-abate sector," language that positions marine shipping fuel, an industry facing genuine and difficult decarbonisation challenges given the scale and duration of ocean freight operations, as exactly the kind of technically difficult sector where blended public-private capital structures can help bridge the gap between demonstrated pilot-scale technology and full commercial deployment.

Rice Investment Group's participation as lead investor, a US-based energy sector-focused fund, alongside Canada's public growth fund vehicle, gives the financing a structure combining domestic public policy-driven capital with private energy sector investment expertise, similar in pattern to other blended finance structures covered elsewhere in recent reporting, where public capital absorbs early-stage risk specifically to attract private investors who might otherwise view the technology as too unproven for direct commercial investment at this stage.

 

What Comes Next

 

EnerPure, founded in 2009 in Manitoba and now headquartered in Calgary, has already demonstrated its technology at pilot scale, and this financing specifically funds the transition from that pilot validation to genuine first commercial-scale operation. Whether the company's modular recycling facilities perform reliably at commercial volume once the Alberta facility comes online in 2028, and whether the underlying economics of small-scale, regionally distributed used motor oil processing prove genuinely more cost-competitive than centralised re-refining at the volumes EnerPure is targeting, will determine how successfully this technology scales into the broader network of recycling facilities the company envisions beyond this initial commercial plant.
