Replace Coal and LNG with Carbon-Negative Biomethane

On-site biomethane generation for process heat, steam generation, and chemical feedstock — delivered via pipeline or virtual wheeling at rates competitive with fossil fuels.

The Challenges You Face

EU Carbon Border Adjustment Mechanism (CBAM)

Sasol's European chemical exports face €75-100/tCO₂e CBAM tariffs starting 2026 — adding R1.4-2.0bn annually to export costs. Coal-based process heat accounts for 70-85% of Scope 1 emissions.

Fossil Fuel Price Volatility

LNG imports averaged R35-45/GJ in 2025 (4× historical Mozambique gas). Coal prices up 180% since 2020. Long-term biomethane BSAs provide 15-25 year price certainty.

Energy Supply Chain Risk

SA heavy industry relies on Mozambique gas (pipeline sabotage risk), imported LNG (forex), and Eskom grid (55% availability). Behind-the-meter biomethane eliminates all three dependencies.

Commercial Partnership Models

TerraFerm Africa offers three flexible commercial structures for heavy industry biomethane deployment:

Biomethane Supply Agreement (BSA)

Long-term fuel offtake (15-25 years)

  • Take-or-pay biomethane delivery at fixed or indexed pricing
  • Pipeline injection or virtual wheeling to facility
  • Volume commitments: 50-500 TJ/year (scalable to demand)
  • Pricing: Competitive with coal and LNG, CPI-linked escalation
  • No upfront CAPEX required

Behind-the-Meter Generation

On-site biogas CHP for process heat + power

  • TFA finances and operates biogas infrastructure on adjacent land
  • Energy-as-a-service model: Pay per GJ consumed
  • Combined heat and power: 85% total system efficiency
  • Direct thermal energy (120-180°C) for steam, boilers, dryers
  • Zero grid dependency, zero fossil fuel exposure

Carbon Credit Bundling

Biomethane + verified carbon removal credits

  • Biomethane supply with Verra/Gold Standard carbon credits (2.1 tCO₂e removal per MWh)
  • Scope 1 emission reduction claims for direct fuel combustion
  • EU CBAM compliance documentation
  • Premium pricing or voluntary market revenue share options

Scope 1 Decarbonization

Result: Eliminates Scope 1 emissions + CBAM tariffs while achieving cost parity with fossil fuels.

Technical Specifications

85% Total System Efficiency

  • Combined Heat and Power (CHP): 42% electrical + 43% thermal
  • Thermal energy delivered at 120-180°C for process heat
  • Applications: Boiler replacement, drying, distillation

1:1 BTU Equivalent — Drop-In Replacement

  • Direct Substitution for Natural Gas
  • Pipeline-quality biomethane: 97% CH₄ purity
  • Calorific value: 35-38 MJ/m³ (equivalent to LNG)
  • No equipment modifications required (burners, boilers, turbines)
  • Proven technology: 20,000+ biogas plants operating globally

15-25 Year Supply Agreements

  • Long-Term Price Certainty
  • Fixed or indexed biomethane pricing with CPI-linked escalation
  • Hedge against fossil fuel volatility and carbon tax increases
