Advantages of Gas Thermal Remediation over electrical

By decoupling the heating process from the electrical grid, Gas Thermal Remediation offers a more sustainable, flexible, and cost-effective path to achieving stringent site closure goals.

When dealing with stubborn soil and groundwater contamination, In-Situ Thermal Remediation (ISTR) is one of the most effective methods available. However, a major hurdle for many remediation projects is figuring out how to power the intense heat required to volatilize contaminants. While traditional thermal conduction heating relies heavily on electricity, Gas Thermal Remediation (GTR™) utilizes natural gas or propane to supply the energy needed to heat the subsurface.

This shift from electrical-powered heating to gas-powered heating provides several distinct advantages for environmental cleanup projects:

1. Overcoming Electric Grid Limitations

One of the biggest setbacks of electrical thermal remediation is the massive strain it places on local power grids. GTR™ sidesteps this issue entirely. By using natural gas or propane as the primary heating fuel, a GTR system only requires nominal electric power to run peripheral components, such as blowers and burner controls. This electrical load is comparable to what is already available at typical commercial or industrial sites, meaning it requires much less electricity than alternative thermal remediation vendors. This effectively overcomes limitations in electric grid capacity and eliminates the need for large, costly power grid upgrades before a project can even begin.

2. Complete Off-Grid Flexibility

Because the electrical requirement is so low, GTR™ offers incredible flexibility for remote projects. In areas where power is completely unavailable, the entire system can be operated entirely off the grid using a standard mobile generator. This makes it an ideal solution for distant or undeveloped sites that electrical systems simply cannot feasibly reach.

3. Precision Control and Energy Savings

Unlike some electrical systems that heat entire blocks of land uniformly, GTR™ utilizes individually controlled burners. This allows project managers to turn off specific burners as localized areas within the target treatment zone reach their specific remediation goals. This surgical approach to heating prevents wasted energy on already-clean soil, translating directly to significant overall energy and cost savings.

4. Lower Costs and Reduced Carbon Emissions

Ultimately, the combination of using commercially available fuel, avoiding grid upgrades, and employing precision burner control results in a highly efficient system. GTR™ affords substantive reductions in overall project energy costs and carbon emissions when compared to heavy electrical loads
