Unprocessed biogas can't be injected into natural gas grids or used as vehicle fuel due to purity requirements (typically 96-98% CH₄). Source: IEA Global Hydrogen Review 2024
Combusting raw biogas in engines or boilers loses 20-30% efficiency compared to upgraded biomethane, increasing operational costs.
Stringent emissions standards (e.g., EPA's RFS Program or EU's RED II) require biomethane to meet >97% methane purity for incentives.
H₂S and moisture in raw biogas accelerate corrosion in pipes and engines, leading to costly maintenance (up to $50,000/year for large plants).
Biomethane qualifies for renewable fuel credits (RINs, LCFS), which can add $1.50–$3.00/mmbtu to your revenue. Source: AGF Renewable Natural Gas Study 2025
