Optimisation of biogas plant with focus on operational stability

Init entered an R&D collaboration with the biogas plant GrønGas, focusing on increasing operational stability, reducing downtime, and improving service quality through systematic implementation of technical solutions and ongoing optimisations.

Through close dialogue, concrete actions, and continuous adjustments, Init met GrønGas’ requests regarding raw material sorting, gas quality, and operating conditions.

 

The biogas plant based in North Jutland, GrønGas, focuses on stable production of green gas at the company’s facility. The biogas company combines chemical and process engineering expertise with modern technology to deliver sustainable green gas to the Danish gas grid, benefiting both industry and private households.

Ambition

Robust solution for operational reliability & raw material flexibility

GrønGas faced challenges with operational reliability, production volatility, flexibility in raw material handling, and the need for stable gas production despite variations in raw materials and changing operating conditions.

 

Unpredictable processes and downtime in key units made planning, resource utilisation, and long-term optimisation difficult and cumbersome. A more robust and reliable solution was needed – one that could handle different raw material quality and operating conditions while ensuring stable gas production.

Grøngas H2

We have a plant that runs all the time, so if an error occurs, we need to react quickly. The most important thing for me is that it works and the service is high. That’s what we get with Init.

Christian Damsgaard, Operations Manager, GrønGas Vrå.

Solution

PLC upgrades & automated dosing

Init implemented an integrated solution at GrønGas that combines PLC upgrades, a flexible raw material handling system, and automatic dosing of iron powder. This approach is supported by data-driven monitoring and KPI management, making implementation step-by-step with clear milestones and targeted training for operations and maintenance.

 

After implementation, the expected results include increased operational stability and more predictable production, reduced downtime, improved gas quality, and lower cost per unit of biogas.

 

Continuous follow-up and adjustments help ensure that GrønGas can maintain and increase business results by adapting to changes in raw materials and operating conditions.

The collaboration works really well, and we can always reach someone who knows what we’re talking about.

Result

Downtime reduced & gas quality improved

The implementation of Init’s solution at GrønGas has led to significant improvements in operational stability and predictable production. The combined approach – integrating PLC upgrades, a flexible raw material handling system, and automated iron powder dosing – has minimised machine downtime and increased production efficiency.

 

With data-driven monitoring and KPI management, GrønGas now has clear measurement points and a continuous optimisation module, enabling quick adjustments in operations and maintenance.

 

Compared to the baseline, gas quality is expected to be more consistent despite varying raw materials, and the cost per unit of biogas has been reduced. Finally, ongoing follow-up and knowledge transfer ensure that GrønGas can maintain improvements and accommodate new raw material and operating conditions in the future.
