Solution

VRU for Stage 3 Retail Fuel Stations

Gasoline vapor emissions (VOCs) during tanker unloading are an ESG liability — and a hidden fuel loss.
GASminer is a Stage-3 VRU for retail fuel stations that captures these vapors and converts them into recoverable fuel value, with no operational disruption.

What GASminer delivers
  • Vapor capture at unloading: engineered for real-world station workflows
  • Recoverable value: collected vapors become usable fuel value (site-level benefit)
  • ESG compliance support: VOC emission reduction with measurable reporting
  • Network readiness: built for multi-site rollout with standardized procedures
Why Stage-3 matters

Stage-1/2 solutions often require additional infrastructure or are not optimized for emerging-market conditions.
Stage-3 recovery at the retail site is a practical path to immediate impact and scalable deployment.

Gasoline Evaporaton

When 32,000 liters of gasoline are transferred into an underground storage tank, the total volume of displaced exhaust gas—consisting of gasoline vapor, air, and water vapor—is theoretically 32,000 liters. Under ambient conditions of around 35°C, with the gasoline having a vapor pressure of approximately 60 kPa, about 48 liters of gasoline are estimated to exist as vapor, equivalent to an evaporation ratio of roughly 0.15%. 

Required cooling capacity for liquefaction 

To recover 48 liters of gasoline as liquid, a total cooling duty of 5,482 kcal is required. This is thermally equivalent to the refrigeration needed to freeze 69 kg of water into ice. Since this cooling duty must be delivered within the 32-minute loading period, the required refrigeration capacity is approximately 3.4 RT.

Moreover, achieving a 95% vapor-to-liquid recovery rate requires the gasoline vapor to be cooled to a temperature of below -30°C.

Therefore, delivering 3.4 RT at -30°C necessitates a large refrigeration unit of at least 9 HP. Such a requirement inevitably increases system size, power consumption, capital cost, operational complexity, maintenance burden, and failure risk.

GASminer’s core technology 

GASminer is equipped with a unique and proprietary heat-exchange technology. Its key innovation lies in achieving the required liquefaction performance with only a 3 HP refrigeration system.

No other product in the world has achieved this level of technical capability—GASminer stands alone. This technological advantage enables the lowest cost, the highest performance, the easiest operation, and long-term stable durability.

Deployment

ZERO CAPEX

Between Phase 1 (Pilot) and Phase 2 (Rollout), GASminer can either be purchased outright or deployed through a zero-CAPEX rental program — giving operators flexibility in how they scale. With the rental program, there is no upfront CAPEX, and monthly fees are paid out of the value of recovered gasoline — keeping the customer’s capital spend at zero over time. 

Phase 1 — Pilot (2–6 sites)

  • Site survey & installation plan

  • On-site installation & commissioning

  • Baseline measurement and initial performance report

  • Operator training and safety checklist

Under the rental program, there is no upfront CAPEX at installation, and the monthly rental fee is covered by sharing the value of recovered gasoline — so the customer’s capital outlay effectively remains zero over time.


Phase 2 — Rollout (20–100 sites)

  • Standardized installation & O&M package

  • Deployment playbook (process, tools, reporting format)

  • Network-level monitoring and maintenance schedule

  • Regional partner onboarding (if needed)

Phase 3 — Scale (100+ sites)

  • Regional expansion with predictable O&M

  • Performance reporting framework for ESG/operations teams

  • Continuous improvement loop based on field feedback

Case

Jakarta Deployment — Best Practices

We validated multi-site installation and operation under real retail constraints, including hot weather and busy station traffic.

What we learned

  • Repeatable installation process reduces site-to-site variance

  • Operator training and daily checks are key to stable performance

  • Standardized reporting enables network-level rollout decisions

  • Together, these learnings form a rollout playbook for new countries and networks.

Pick the Market, Select the Station - But Never Compromise on VRU Performance
In vapor recovery, many factors influence profitability — but performance defines it.
  • Throughput determines the overall scale of the opportunity.
  • Fuel price determines the economic value per recovered liter of gasoline.
  • Recovery performance determines whether that value is actually realized — or lost. 
  • → Markets and stations can be chosen strategically to optimize volume and price, but recovery rate depends entirely on the VRU technology you select. 
  • → The analysis shows that choosing the highest‑performing VRU is the rational pathway to both profitability and ESG impact for all stakeholders.
