DM-XTech · DM-X CBM
From Azolla fern to compressed biomethane — a vertically integrated, peso-denominated LPG substitute for Philippine households.
Azolla pinnata, the floating water fern native to Philippine wetlands, is one of the fastest-growing plants on earth. Under tropical conditions it doubles its mass every 3 to 5 days without any synthetic nitrogen fertilizer — because it hosts a symbiotic nitrogen-fixing cyanobacterium (Anabaena azollae) inside its leaf cavities.
When this biomass is fed into an anaerobic biodigester, it produces biogas with approximately 50% methane — the same combustible gas that makes LPG useful for cooking. After water scrubbing to remove CO₂ and compression into cylinders, the result is DM-X CBM: a 100% domestically-produced, carbon-neutral cooking fuel.
Azolla grows on leased Philippine farmland, cultivated by Filipino workers, compressed using Philippine electricity. The entire cost structure is peso-denominated and immune to US-dollar LPG import price shocks, Strait of Hormuz disruptions, or Brent-linked freight premiums. This is not merely a cheaper fuel — it is a more resilient fuel.
| Parameter | Specification | Note |
|---|---|---|
| Methane purity | ≥97% CH₄ | Post-PWS upgrading; verified by online GC |
| H₂S content | ~50 ppm retained | Natural odorant; bypass blending from raw gas. Higher than synthetic THT (~5–15 ppm eq.) but functional. |
| Storage pressure | 200 bar(g) | CNG-rated Type-I cylinders (ISO 11439); NOT standard LPG cylinders |
| Stove compatibility | Standard LPG stoves & regulators | Drop-in swap; no appliance modification |
| Distribution | Door-to-door cylinder swap | Same form factor, DM-X owned fleet |
| Carbon status | Biogenic carbon cycle | Eligible for Verra VM0041 / Gold Standard thermal methodologies, pending project-specific validation |
DM-X CBM is stored at 200 bar(g) in CNG-rated Type-I steel cylinders certified to ISO 11439 / DOT-NGV standards. Standard LPG cylinders are rated for approximately 25 bar and must never be used for CBM. The consumer-facing value proposition is unchanged — same stove, same regulator, same flame — but the cylinder infrastructure is CNG-grade, not LPG-grade.
The same flame, the same stove, the same monthly bill — but an entirely different supply chain underneath.

The flame is identical. Everything behind it is different. For the household: same bill, zero switching cost, stable supply. For the country: zero FX drain, zero geopolitical exposure, every peso retained domestically.
The DM-XTech business model is end-to-end vertically integrated: we control the cultivation of our own feedstock, the gas processing, and the final distribution.
DM-XTech leases shallow wetland, paddy, and fish-pond land in the vicinity of each processing hub. Rental contracts are multi-year with stepped escalation tied to the Philippine CPI. Landowners receive guaranteed peso-denominated income without any farming obligation of their own.
₱100,000 / ha / year
DM-XTech's own cultivation teams manage inoculant deployment, water management, harvesting, and transport. No third-party farmer supply, no spot-market price exposure. Feedstock cost is locked at ₱0.80/kg equivalent.
150 t fresh / ha / yr (conservative tropical baseline)
Sealed anaerobic CSTR tanks. Mesophilic bacteria produce raw biogas at ~50% CH₄ / 50% CO₂. Hydraulic retention time 25–30 days. Digestate exits as nitrogen-rich organic fertilizer.
~250 L CH₄ / kg VS (base case); up to 280 L/kg VS (upside)
Pressurized Water Scrubbing at 8 bar(g) strips CO₂ preferentially. No solvents, no membranes, no chemical regeneration. Water is recycled in a closed loop. CH₄ slip: 1.5–2.5% (standard for PWS).
≥97% CH₄ product purity
Four-stage oil-free compressor fills CNG-rated steel cylinders to 200 bar(g). Each 50L cylinder holds ~10 Nm³ CBM, equivalent to ~8 kg LPG by heating value.
50 Nm³/h nameplate per hub
Door-to-door cylinder swap. Drop-in substitute for LPG in any household stove — no appliance modification required. The CO₂ released is the same CO₂ the azolla absorbed weeks earlier.
~2,000 households served per hub
DM-X CBM is not fossil fuel. The CO₂ released when a Filipino household cooks with it is the same CO₂ that was pulled from the atmosphere four weeks earlier by a growing azolla fern. No new fossil carbon enters the cycle.
Carbon dioxide in the air above the cultivation paddy.
Fronds absorb CO₂ and fix it into biomass. Doubles every 3–5 days.
Harvested azolla fermented to biogas, upgraded to ≥97% biomethane.
Methane burns, releasing the same CO₂ absorbed weeks earlier.
The biogenic carbon cycle makes DM-X CBM eligible for Gold Standard Verified Emission Reductions (VERs) under thermal-energy displacement methodologies and Verra VM0041 for methane recovery, subject to project-specific validation and third-party verification. Each tonne of LPG displaced represents approximately 3.0 tonnes of avoided CO₂-equivalent — independently auditable and countable against Philippine Nationally Determined Contributions.
Before looking at national deployment, it helps to see exactly what a single hectare of DM-X cultivation produces — and what it displaces.
| Step | Input / Output | Value |
|---|---|---|
| 1 Hectare leased | Marginal rice paddy or fallow wetland | ₱100,000/yr rent |
| → 150 t fresh azolla | Harvested over 12 months at ~12.5 t/month | — |
| → 3,150 Nm³ biomethane | After digestion, scrubbing, and upgrading | ₱252,000 gross revenue |
| → 315 × 50L cylinders | Filled at 200 bar · ~10 Nm³ per cylinder | — |
| → 2.5 tonnes LPG displaced | Imported fuel no longer required | ₱150,000+ forex retained |
| → ~7.5 tCO₂e avoided | Per hectare per year | Eligible for VERs |
The values compound linearly with scale — two hectares produce twice the cylinders and displace twice the LPG. Because every step uses only domestic inputs and the gas-processing plant has economies of scale, unit margins actually improve as more hectares are added to the same hub's cultivation radius.
What happens when the program goes national? Each hub is a standard plant — 50 Nm³/h nameplate, 82% utilization in steady state.
