Radio-frequency direct heat replaces combustion where industry needs heat most: heavy oil, minerals and carbon capture. One platform, three markets, publicly listed in Calgary.
Fig. 1 · RF heat starts in the core. Combustion heats the surface and waits.
Field Core is a solid-state radio-frequency inverter. It turns grid or on-site power into RF energy tuned to the material in front of it, so heat is generated inside the oil sand, the ore or the amine itself. Nothing is burned and nothing is heated from the outside first.
Downhole RF heating mobilizes bitumen in place. No steam, no water, no solvent.
Commercial pilot complete A · 02Ore and potash drying, heap-leach heating. Moisture leaves as vapour, with no burner stack.
Paid feasibility A · 03Replaces the steam reboiler in carbon capture and gas sweetening units.
Field pilot 2027The same block of material, heated two ways. A burner can only push heat through the surface, so the surface overheats while the core waits and the stack carries a third of the fuel away. RF energy couples into the material's molecules directly, so the whole volume warms together and the core leads. Press play, or drag the timeline.
Hot gas at 300 °C on every face · conduction does the rest
27.12 MHz field through the volume · power trims at target
Target: core at 120 °C. Press play.
Illustrative 2-D model · not test dataIn this model the RF core reaches 120 °C in less than half the time. The bottleneck in combustion heating is conduction, and conduction is slow in ore, oil sand and amine.
Burner-side surfaces run near 300 °C to push heat inward. That is where ore cracks, bitumen cokes and amine degrades. RF holds the surface below the core.
There is no flue gas to carry heat away and no on-site combustion CO₂. The losses that remain are electrical, inside the inverter, and they are measurable.
Each market is at a different gate, and each gate is evidence for the others. The hardware is common across all three; only the applicator changes. Status below is as of October 2026.
A downhole antenna heats the reservoir directly. Oil warms, thins and drains to a producer below it. No water is sourced, boiled, recycled or disposed of, and the surface footprint is one inverter skid per well pair.
Partner type: an intermediate Western Canadian heavy oil producer. First commercial FID targeted Q2 2027.
Rotary dryers burn gas to heat air to heat rock. Field Core drives an applicator over the belt and heats the water inside each particle directly. The same platform warms heap-leach pads to speed copper recovery in cold months.
Partner types: a top-3 global diversified miner (copper heap leach, South America) and a Saskatchewan potash producer consortium (drying).
Every gas sweetening unit and most carbon capture plants boil amine to release CO₂, usually with a gas-fired steam reboiler. Field Core heats the amine in the regenerator sump directly, with no hot tube walls and no fired heater on site.
Partner types: a Western Canadian midstream operator (host site) and a federal clean-technology program ($2.0M, fictional).
Enter your reboiler duty and your prices. The estimator compares what you burn today, carbon included, with the electricity Field Core would draw, and tells you the power price where they break even. The formula is printed underneath. Sometimes the answer is no, and we would rather you knew that first.
Break-even electricity price: $57.41/MWh. Below that, RF costs less to run than your reboiler.
Scope 1 only. CO₂e avoided counts combustion at your site. Emissions from the electricity supply depend on your power source and are not included. Carbon cost assumes full exposure; your compliance position may differ.
Send these numbers to an engineer# per year fuel_GJ = duty ÷ efficiency × hours = 30 ÷ 0.82 × 8,400 = 307,317 GJ CO2e_t = fuel_GJ × 0.050 = 15,366 t today_$ = fuel_GJ × gas_$ + CO2e_t × carbon_$ = $2,612,195 RF_MWh = duty × (1 − reduction) × hours ÷ 3.6 = 45,500 MWh savings_$ = today_$ − RF_MWh × power_$ = $337,195 breakeven = today_$ ÷ RF_MWh = $57.41/MWh
0.050 t CO₂e per GJ is a typical combustion factor for pipeline-quality natural gas, including small CH₄ and N₂O contributions. Use your own factor if you report one.
Energy reduction compares Field Core's electrical input with the thermal duty of the steam reboiler it replaces. Our 25–45% range comes from bench-scale testing on MEA and MDEA blends and will be confirmed in the 2027 field pilot.
Not included: capital cost, the value of removing the fired heater from your permit, and lower amine degradation. A feasibility study prices all three.

Host site for a 2027 slipstream pilot at a sour gas processing plant. Field Core will regenerate a side stream of the plant's existing amine.

About 410 bbl/d of heavy oil from the Lloydminster fairway covers corporate G&A at current prices (management estimate), so development capital goes to the platform.
All three markets run on the same Field Core inverter. A commercial win in any one of them de-risks the hardware, the supply chain and the cost curve for the other two.
A paid study with a top-3 global miner and $3.4M in non-dilutive funding covered roughly 40% of 2025–26 development spend (estimate). Validation is being bought by the customers, not only by shareholders.

Aspen Bend Development Corporation is wholly owned by a First Nation community in the heavy oil fairway where Dielectra produces (both fictional). The partnership was negotiated before the first Field Core well was permitted on the Nation's traditional territory.
Aspen Bend holds majority ownership of the company that installs and services every Field Core unit in the region, and a direct stake in Dielectra itself. The work and the returns from it stay in the community.
“We were asked to own it, not to sign off on it. That is the difference our members noticed.”
Chief Executive Officer, Aspen Bend Development Corporation (fictional)
Aspen Bend's majority share of the joint venture that installs, operates and maintains every Field Core unit in the fairway.
Purchased in the 2025 private placement, on the same terms as every other subscriber.
Paid training through a regional polytechnic, with first hiring preference for Nation members. Eight are filled today.
Plus an observer seat on Dielectra's own board, with access to the same technical reporting as directors.
