Hanwha Power and Pembina Pipeline will assess supercritical CO2 waste heat recovery at gas compressor stations. If successful, the pilot could open a new efficiency lever for midstream.
Hanwha Power and Pembina Pipeline (PBA) signed a memorandum of understanding to evaluate the deployment of waste heat recovery (WHR) power generation systems at Pembina's compressor stations and gas infrastructure. The collaboration targets a lower-carbon electricity source for midstream operations, with pilot project selection and technical-economic feasibility as the immediate next step.
This is an early-stage agreement with no financial terms or deployment guarantees. The better read is that it signals a concrete technology trial in a sector where carbon reduction options are often limited to electrification or offsets. If the pilot succeeds, the same technology could spread to other midstream assets with similar compressor configurations.
The MOU covers joint assessment of pilot candidates at Pembina's network of hydrocarbon liquids and natural gas pipelines, gas gathering and processing facilities, and oil and NGL infrastructure. Hanwha will provide its supercritical carbon dioxide (sCO2) WHR system, a next-generation power generation technology that captures waste heat from gas turbines without additional fuel consumption.
Pembina’s Chris Rousch, Senior Vice President, Commercial, said: “Actively exploring opportunities to enhance the efficiency and long-term value of our operating assets is core to our business at Pembina. Our collaboration with Hanwha creates further opportunity to deliver differentiated value for our customers and stakeholders.”
Conventional waste heat to power uses organic Rankine cycle (ORC) systems, which work with low-temperature heat but require larger equipment and sometimes water for cooling. Hanwha’s sCO2 system uses a working fluid with both liquid and gas properties, enabling a more compact design, 100% water-free operation, and uncrewed operation. The company claims better performance and a non-explosive, non-toxic working fluid compared to ORC.
Key insight: The water-free aspect is especially relevant in Alberta, where water use is restricted in many oil and gas operations. If sCO2 WHR can operate reliably in arid conditions, it removes a constraint that limits adoption of alternative lower-carbon technologies.
Compressor stations are the largest energy consumers on a gas pipeline network. Gas turbines drive compressors to move gas, and a significant portion of input energy is lost as waste heat. WHR systems capture that heat to generate electricity, which can then offset station power demand or be exported to the grid.
For midstream operators, the appeal is straightforward: improve asset efficiency and reduce carbon intensity without a separate fuel supply. Pembina’s existing assets include a large footprint of compressor stations, gas gathering plants, and processing facilities that could host multiple WHR units. A successful pilot would create a replicable template across its network.
While no other midstream companies are named in the source, the logical peers are operators with similar compressor-heavy infrastructure in water-constrained regions. That includes:
Investors tracking the sector should note that this is not yet a commercial agreement. The pilot selection and feasibility study will take months, and any revenue or emissions benefit would follow only after a successful multiyear deployment.
Hanwha Power is a division of the Hanwha Group, a South Korean conglomerate active in energy, defense, and chemicals. Its sCO2 WHR system has been tested in other industrial settings but has not yet been deployed at scale on North American pipeline infrastructure. The pilot will need to demonstrate reliability under varying loads, ambient temperatures, and gas turbine operating cycles.
Michael Sicker, Hanwha Power Head of the Americas, said the MOU is “a meaningful first step toward expanding our green energy solutions business in the Canadian market.” He emphasized a combination of ITB-based industrial cooperation (likely referencing Korea’s business model of linking technology supply with investment and trade) and lower-carbon technology.
Confirm: A named pilot site, capital expenditure estimate, and target commissioning date within 12 months. If Pembina allocates a portion of its projected 5% to 7% EBITDA growth through 2030 to WHR deployment, that signals management commitment.
Weaken: Delays in feasibility studies, a pivot to alternative lower-carbon technologies (e.g., electrification via grid renewables), or a decision to focus WHR only on new builds rather than retrofitting existing compressor stations.
The MOU fits into Pembina’s stated goal of enhancing asset efficiency. The company has previously pursued midstream consolidation, including the 2023 acquisition of a 40% stake in its gas infrastructure business by Apollo. That deal freed up capital for organic projects like the Cedar LNG terminal and potential lower-carbon investments.
Pembina’s Alpha Score is 55 out of 100, labelled Moderate. That reflects a balanced risk-reward profile in the energy midstream sector, where the company offers stable fee-based cash flows but faces headline risk from commodity-linked segments and carbon policy uncertainty.
If the Hanwha-Pembina pilot succeeds, the read-through is that sCO2 WHR becomes a credible third option for midstream carbon reduction, alongside electrification and hydrogen blending. That would benefit:
The MOU lacks a timeline for pilot selection. Hanwha and Pembina will jointly assess technical and economic feasibility, then identify candidate sites. The next material event is a public announcement of the chosen pilot location and capital budget. Until then, the agreement is a nonbinding expression of intent.
