South Korea’s Hanwha Power is attempting to position supercritical carbon dioxide power systems as a commercially viable decarbonization tool for pipeline infrastructure operators in Canada.
The company announced that it signed a memorandum of understanding with Pembina Pipeline Corporation to explore deployment of supercritical CO2-based waste heat recovery systems across Pembina’s pipeline booster stations. The agreement focuses on evaluating both technical and economic feasibility within Canada’s midstream energy sector, while also identifying pilot project opportunities tied to broader commercialization efforts in North America.
The partnership reflects a wider shift underway in oil and gas infrastructure strategy. Rather than concentrating exclusively on carbon capture projects or renewable energy procurement, operators are increasingly examining efficiency-driven emissions reduction technologies capable of lowering operational emissions without fundamentally altering existing hydrocarbon infrastructure.
Large pipeline compressor stations, gas turbines, and industrial processing facilities generate substantial amounts of unused thermal energy during routine operation. Traditional waste heat recovery technologies, often based on steam Rankine cycles, have faced deployment limitations in remote or water-constrained regions because of infrastructure complexity, cooling requirements, and relatively lower efficiency at smaller scales.
Hanwha Power’s approach uses supercritical carbon dioxide as the working fluid instead of steam. In a supercritical state, carbon dioxide behaves with characteristics of both a liquid and gas, allowing for higher thermal efficiency and significantly more compact system architecture.
That compactness matters in midstream infrastructure environments where space limitations, modular deployment requirements, and maintenance constraints affect project economics.
The company argues that its system offers three operational advantages particularly relevant to the North American market: higher generation efficiency compared with conventional steam systems, smaller equipment footprints, and waterless operation.
The water issue is increasingly important across western Canada and parts of the United States where industrial water usage faces growing regulatory scrutiny and climate-related resource pressures. Water-intensive thermal systems have become more difficult to justify economically and environmentally in regions already managing drought risks, competing industrial demand, and stricter environmental permitting.
Canada’s federal carbon pricing framework and methane reduction policies continue pushing pipeline and gas infrastructure companies toward operational decarbonization strategies. While upstream oil sands emissions often dominate public debate, midstream infrastructure operators are also facing increasing expectations from investors and regulators to improve efficiency and reduce emissions intensity across transportation networks.
For companies like Pembina, efficiency upgrades offer a relatively lower-risk pathway compared with more capital-intensive decarbonization projects.
Pembina operates one of Canada’s largest energy transportation and midstream networks, with extensive pipeline and gas infrastructure concentrated largely in Alberta and western Canada. Applying waste heat recovery systems at compressor or booster stations could potentially reduce purchased electricity demand or offset onsite power consumption without requiring major redesigns of existing infrastructure.
Although supercritical carbon dioxide cycles have attracted significant interest in power generation research over the past decade, scaling the technology beyond pilot or demonstration projects has proven difficult. Materials durability under high-pressure operating conditions, thermal management complexity, integration costs, and uncertain return-on-investment timelines have slowed broader market adoption.
Economic viability also depends heavily on site-specific conditions including waste heat temperature, operational load consistency, electricity pricing structures, and carbon pricing incentives.
That likely explains why the Hanwha-Pembina agreement currently emphasizes feasibility studies and pilot project identification rather than immediate commercial deployment commitments.
The collaboration also carries geopolitical and industrial implications extending beyond energy efficiency technology alone.
Hanwha stated that the initiative is linked to the Industrial and Technological Benefits strategy associated with the Canadian Patrol Submarine Project being pursued by Hanwha Ocean. Canada’s defense procurement framework often requires foreign suppliers to generate domestic industrial benefits and long-term economic partnerships as part of large government contracts.
For South Korean industrial firms, Canada increasingly represents a strategic market tied not only to energy transition opportunities but also to critical minerals, defense cooperation, advanced manufacturing, and North American supply chain access.
Instead of immediate infrastructure replacement, many operators are pursuing incremental emissions reduction technologies capable of extending the operational relevance of existing assets. Waste heat recovery, electrification of auxiliary systems, methane abatement technologies, and digital optimization tools are attracting greater interest because they can often produce measurable emissions reductions while preserving existing industrial economics.
Whether supercritical CO2 waste heat recovery systems can move beyond demonstration-scale adoption remains uncertain. The technology’s long-term competitiveness will likely depend less on technical performance alone and more on installation costs, maintenance reliability, financing structures, and the evolution of North American carbon regulation.
