AI Anaerobic Digestion Control

Grid operators need better ways to handle congestion on transmission or distribution networks, where power flows can exceed safe limits and create reliability and cost issues. It addresses the problem of power grid congestion due to the increasing use of renewable energy sources, which can lead to inefficiencies and higher operational costs. Manual inspection in radioactive environments is slow, risky, and prone to human error.

The Problem

“AI Anaerobic Digestion Control for Stable Biogas Output, Lower Energy Cost, and Safer Plant Operations”

Organizations face these key challenges:

1

Feedstock composition varies daily and is hard to model with fixed rules

2

Lab measurements are delayed and do not support real-time control

3

Operators depend on tribal knowledge rather than consistent decision support

4

Process upsets are detected late, after gas yield has already dropped

5

SCADA alarms identify symptoms but not likely root causes or best actions

6

Energy prices and export constraints make suboptimal operation more expensive

7

Inspection of tanks, pumps, piping, and hazardous areas is labor-intensive and risky

8

Data is fragmented across SCADA, historian, CMMS, lab systems, and spreadsheets

Impact When Solved

Increase biogas and methane yield through better feedstock and control decisionsReduce digester upset events such as acidification, foaming, and overload conditionsLower operating cost from energy, chemicals, maintenance, and emergency interventionsImprove CHP, upgrading, and export scheduling with more accurate gas production forecastsReduce manual inspection exposure in hazardous or hard-to-access plant areasShorten response time from anomaly detection to operator actionCreate a repeatable optimization framework across multiple digestion sites

The Shift

Before AI~85% Manual

Human Does

  • •Review lab results, gas quality readings, and operating trends to judge digester stability
  • •Adjust feed loading, temperature, mixing, and chemical dosing using fixed operating windows and operator experience
  • •Investigate rising VFAs, foaming, methane loss, or gas quality deviations after symptoms appear
  • •Balance methane output, uptime, and compliance with downstream gas quality and equipment constraints

Automation

  • •No AI-driven forecasting or optimization is used
  • •Basic control loops hold temperature, mixing, or pressure at fixed setpoints
  • •Simple alarms flag threshold breaches after process conditions move out of range
With AI~75% Automated

Human Does

  • •Approve recommended changes to loading, co-substrate mix, temperature, mixing, and dosing within operating policy
  • •Decide responses to high-risk instability alerts, gas quality exceptions, and unusual feedstock events
  • •Set production priorities and operating constraints for methane yield, uptime, chemical use, and gas specifications

AI Handles

  • •Continuously monitor process signals and estimate digestion health, methane production, and upset risk
  • •Forecast the impact of feedstock variability and time-lagged biology changes on yield, stability, and gas quality
  • •Recommend optimal operating adjustments to loading, nutrient or alkalinity dosing, temperature, and mixing under plant constraints
  • •Detect anomalies early, prioritize operator alerts, and trigger approved control actions or safe setpoint corrections
