FAQ

Frequently Asked Questions

Short, citation-friendly answers for customers, partners, and AI systems trying to understand what Zolena Lab does.

Is Zolena Lab an ESG reporting company?

No. Zolena Lab is positioned as an AI-powered environmental monitoring technology company. ESG and property-related reports are customer-facing applications of the environmental evidence layer.

What are Zolena Lab's core capabilities?

The four core capabilities are methane monitoring and emissions quantification, oil sands energy-efficiency decision support, pollution source attribution and regional transport identification, and PEMS for industrial facilities.

What is QMRV and how does Zolena Lab use it?

QMRV means quantification, monitoring, reporting, and verification. For Zolena Lab, QMRV is a data and evidence workflow: we support measurement, emissions quantification, monitoring records, and report-ready datasets. We do not provide statutory compliance determinations, legal verification, regulatory approval, or carbon-credit certification.

How does PEMS differ from CEMS?

A CEMS relies on dedicated continuous emissions monitoring hardware at the stack. A PEMS predicts emissions from process parameters and validated models. Zolena Lab's PEMS work uses site-specific training, validation, and transparent machine-learning model architecture rather than treating prediction as a generic black box.

What is a One-Unit NOx PEMS Pilot?

A One-Unit NOx PEMS Pilot is a limited technical project for one operating combustion unit. It uses existing process data and same-period plant NOx measurements to assess model feasibility, data quality, operating-condition performance, abnormal divergence, and internal missing-data examples. It is not regulatory approval, CEMS replacement, RATA, certification, or formal reporting approval by itself.

What is PEMS-Ready Project Integration Service?

PEMS-Ready Project Integration Service is a coordination service for new or upgraded combustion projects that may need future NOx predictive emissions modeling. Zolena Lab coordinates PEMS data requirements, system interfaces, commissioning data preservation, model-development planning, and third-party validation coordination where required, without acting as the EPC, CEMS installer, controls designer, stack-testing firm, or permitting consultant by default.

What is a PEMS Second Opinion and Model Performance Review?

It is a technical due-diligence review of an existing PEMS model, supplier proposal, validation report, input-variable set, data sufficiency claim, or model-versus-instrument divergence issue. It can identify unsupported assumptions, weak validation logic, operating-condition bias, data-quality gaps, and questions for further testing. It is not certification or regulatory approval.

Can a PEMS model prove CEMS drift?

No. A PEMS model can flag unexpected divergence between predicted NOx and plant instrument data, but it cannot by itself prove CEMS drift. Divergence should trigger review of instrument condition, calibration history, operating context, data quality, and, when needed, qualified testing.

What data is needed for a NOx PEMS pilot?

A first review normally needs the unit type, project stage, whether same-period NOx instrument or CEMS data exists, the data coverage period, a preliminary process-variable tag list, timestamps and sampling frequency, and known missing or invalid data periods. Six to twelve months is preferred; around three months may be reviewed if operating-range coverage is strong.

What is the reference case for PEMS validation?

The reference PEMS case reported 28 months of industrial field validation, 99.93% data availability, MAE of 0.5982, r value of 0.9451, and a 0.14% total-emissions difference in the test set. The 99.93% figure is data availability, not prediction accuracy.

Can PEMS be transferred directly to any facility?

No. PEMS models are site- and equipment-specific. A new facility requires suitable process data, model training, calibration, and validation before use.

What satellite data does Zolena Lab use?

Zolena Lab uses satellite and remote-sensing data according to the project question and data availability. Land and EUDR evidence work may use suitable satellite imagery for screening and documentation, while regional transport interpretation may use CALIPSO aerosol optical data and MERRA-2 meteorological reanalysis. No single sensor, resolution, or data source is promised for every application.

Can satellite evidence replace field investigation?

No. Satellite evidence supports screening, context review, and documentation. It cannot directly observe subsurface contamination or replace all field sampling, laboratory testing, or qualified local review.

How does Zolena Lab approach methane monitoring?

Zolena Lab frames methane monitoring as a tiered evidence workflow that can combine satellite screening, continuous low-cost sensor networks, machine-learning calibration, hotspot identification, anomaly detection, trend analysis, and report-ready data support.

What is pollution source attribution?

Pollution source attribution uses environmental monitoring data and scientific methods to identify likely pollution sources and their relative contributions. Zolena Lab describes PMF, CMB when source profiles are available, regional transport analysis, and OFP analysis as distinct tools with different data requirements.

Who are Zolena Lab's typical partners?

Typical partners include environmental engineering firms, field-service providers, EPC teams, laboratories, project developers, and regulatory-facing consultants that need an algorithm, remote sensing, data, or technical evidence layer.

Does Zolena guarantee regulatory approval or legal compliance?

No. Zolena Lab provides monitoring data, analytical evidence, and report-ready technical support. Statutory compliance, regulatory approval, legal responsibility, carbon-credit verification, and formal assurance outcomes depend on qualified third parties, local rules, field evidence, and the specific use case.
