Transforming Landfill RNG Economics with Low-Cost INTRUPTor™ Technology

By Hydron Energy

Hydron Energy’s INTRUPTor™ technology uses novel biomimicry-based metal-organic framework (MOF) sorbents developed and manufactured by Hydron Energy. These advanced sorbents represent a significant improvement over current industry standards for biogas upgrading, particularly for landfill gas applications. Hydron’s MOFs are designed to remove nitrogen (N₂) and carbon dioxide (CO₂) near ambient pressure in a single step, a capability that simplifies system design and operations while reducing both capital and operating costs compared with incumbent technologies.

Conventional biogas upgrading systems often face major limitations when processing landfill gas. Landfill biogas can contain elevated nitrogen concentrations, which are difficult and costly to remove. Traditional approaches typically require very tight contaminant control pre-treatment steps, higher operating pressures, a combination of adsorption and membrane technologies in multiple separation stages for N₂ and CO₂ removal, and complex balance-of-plant systems. These requirements increase energy consumption, equipment costs, maintenance needs, and overall operational complexity, often limiting the financial viability of landfill RNG projects.

INTRUPTor™ rapid-cycle sorption technology addresses these challenges through a regenerative, streamlined platform. By utilizing structured MOFs in a single stage at near-ambient pressure, the system utilizes low-quality steam to rinse out contaminants alongside captured N₂ and CO₂ to deliver pipeline-quality renewable natural gas (RNG) without the need for multi-stage processing. Due to its regenerative cyclic operation, the INTRUPTor™ can easily tolerate and reject higher levels of contaminants compared to other industrial solutions. This simplifies pre-treatment configuration and supports easier deployment, smaller system footprints, reduced consumables energy consumption, and more straightforward operation compared with conventional upgrading solutions.

The INTRUPTor™ platform represents a pivotal step toward transforming the economics of RNG production from landfill sites. By combining two of the most challenging separation steps into one efficient process, Hydron’s solution enables producers to achieve market-acceptable RNG quality at a materially lower cost. This can improve the viability of landfill projects of varying sizes, creating tangible economic value for developers, operators, municipalities, and other stakeholders.

Using conventional biogas upgrading technologies, RNG often struggles to compete directly with fossil fuel-based natural gas on cost. Hydron’s INTRUPTor™ offers a game-changing pathway to close that gap. By reducing complexity, lowering costs, and improving project economics, the technology makes RNG more competitive with fossil natural gas while supporting the broader transition to cleaner energy.
