Understanding Renewable Natural Gas: Definitions, Process & Production Pathways

What Is Shell Renewable Natural Gas? (RNG)

RNG, sometimes referred to as biomethane, is a purified form of biogas produced from organic waste through anaerobic digestion or gasification processes. After upgrading to meet pipeline quality standards, it is interchangeable with conventional natural gas for most applications, including heating, electricity generation, vehicle fuel (renewable gasoline), and direct industrial use.

RNG at the Intersection of Agriculture, Forestry, and Industry

The key to RNG’s broad appeal is its feedstock flexibility—manure, crop residues, animal byproducts, forestry residues (bark, sawdust), organic municipal waste, and more can feed digestion systems. This enables both rural and industrial operations to generate energy locally, close resource loops, and minimize transportation-dependent emissions.

Process Flow: Turning Waste into Energy

1. Collection: Gather organic waste streams from agriculture, livestock operations, forestry, or municipalities.
2. Digestion: Feedstocks undergo anaerobic digestion (microbial breakdown in oxygen-free environment) or thermal gasification.
3. Biogas capture: Raw biogas (mainly methane/CO₂ mix) is collected.
4. Upgrading: Biogas is purified to remove CO₂, water, and impurities—resulting RNG meets strict quality standards for pipeline injection.
5. Distribution & use: RNG is transported via pipelines or on-site for power, heating, drying, vehicle fuel, or industrial consumption.
6. Digestate: Solid/liquid nutrient-rich byproduct from digestion is applied as fertilizer, closing the nutrient cycle.

• 🔄 Flexible Feedstocks: Manure, crop residues, food waste, bark, sawdust, and municipal solids
• 🌍 Versatile Use Cases: Powering farm equipment, drying crops, providing heating for greenhouses, blending into natural gas for industrial operations
• 🚜 Supports Decarbonization: Mining, agriculture, forestry, and remote infrastructure with heavy energy needs
• ⚡ Renewable Gasoline Option: Purified biomethane can be used directly in CNG/LNG fleets as low-carbon fuel
• 🌾 Soil & Nutrient Benefits: Digestate returns as organic fertilizer, enhancing fertility and soil health

How Shell’s RNG Bridges the Gap Across Sectors

Shell renewable natural gas serves as a bridge from nonrenewable natural resources to sustainable, low-carbon alternatives in multiple industries. By focusing on resource-intensive sectors—agriculture, forestry, mining, and infrastructure—Shell’s innovation enables widespread reductions in methane and CO₂ emissions while supporting economic resilience in rural communities and heavy industrial zones.

• 🏭 Industrial Operations: RNG facilitates emission reductions without requiring disruptive equipment overhauls, especially where natural gas networks are in place.
• 🌳 Forestry: Converts wood-processing waste into energy, reducing landfill burdens and supporting circular economy models.
• 🚜 Agriculture: Empowers farmers with local RNG production from manure/crop residues, providing on-site power and fertilizers.
• ⛏️ Mining & Remote Infrastructure: Replaces diesel with cleaner RNG for machinery, generators, and transportation at off-grid or hard-to-access sites.

Sources of RNG: Waste Streams in Agriculture, Forestry & Mining

The greatest advantage of RNG is the diversity and abundance of feedstocks it can utilize:

• 🐄 Agricultural/Livestock: Manure from large-scale facilities, crop residues (corn stover, rice straw), food and animal-processing wastes
• 🌲 Forestry: Bark, sawdust, pulp, wood chips, processing scraps left untreated would otherwise emit methane
• 🏙 Municipal: Household organic waste, yard trimmings, sludge from municipal wastewater facilities
• ⚒️ Mining: Tailings, organic matter from remote mineral operations, waste from site infrastructure

Key Process: Anaerobic digestion excels at converting these waste streams into biogas, subsequently upgraded to RNG for direct use or injection into local pipeline networks.

RNG in Agriculture: Livestock, Crop Residues, and Beyond

For modern farming operations, managing manure and leftover crop residues is both a nutrient challenge and a greenhouse gas risk. On-farm digestion systems that convert this surplus into biogas have seen rapid growth, especially in livestock-rich regions.

• ✔ Methane Management: RNG capture diverts potent methane emissions that would otherwise escape into the atmosphere.
• ✔ Nutrient Cycling: Digestate byproduct is used as an organic fertilizer, closing the loop for soil fertility and reducing synthetic input reliance.
• ✔ Energy Generation: RNG powers farm equipment, greenhouses, feeding operations, and is even used for crop drying or food processing.
• ✔ Production Consistency: Livestock and crop wastes are generated year-round, providing a predictable supply for RNG systems.

In this way, Shell renewable natural gas supports farmers to generate on-site or near-site energy, cut operating costs, and create a new income stream from agricultural byproducts—while aligning with national and global sustainability goals.

Renewable Natural Gas in Forestry: Wood Waste to Clean Energy

Forestry industries generate significant volumes of bark, sawdust, and wood-processing residues—biomass that, when left untreated, can emit methane or add to landfill challenges. RNG systems in wood processing centers (sawmills, pulp mills, chipboard factories) present new pathways:

• ✔ Valorize Waste: Bark, sawdust, and offcuts that would otherwise become landfill waste feed RNG digesters and gasification units.
• ✔ Distributed Generation: Facilities generate their own energy for heating, drying, processing wood products, or grid injection.
• ✔ Enhance Circularity: By returning digestate (with certain process controls) to managed forest lands, these systems boost soil carbon and nutrient levels.

Mining and Infrastructure: The Potential of RNG

Mining and related industries are heavily energy-intense, often dependent on diesel and other nonrenewable fuels for machinery, conveyance, and remote-site power generation. Here, RNG presents a unique opportunity to not only cut direct emissions but to improve fuel security and lower long-term costs:

• ✔ Implementing RNG: Deployment of RNG, blended with existing natural gas or as a sole fuel, reduces reliance on trucking fuel to remote sites and decreases volatility in operating costs.
• ✔ Operational Resilience: RNG enables mines to meet new environmental standards and commitments to reduced carbon operations.
• ✔ Soil Rehabilitation: Digestate from on-site digestion can aid soil management and revegetation in mine-affected lands, supporting post-mining recovery.
• ✔ Distributed Infrastructure: With digesters on or near mine sites, companies can build a more resilient, distributed energy infrastructure.
