"Advised on over 350 plants.
Every assessment is based on 20 years of practical experience and measurable results."

TECHNICAL & BIOLOGICAL CONSULTING

Since 2002, we have provided technical and biological consulting for over 350 biogas plants. This is not just about the technology – the biological factors account for at least 50% of the success.

Our consulting services:

Result: Measurably higher gas yield at lower costs.

DUE DILIGENCE

Are you buying or selling a biogas plant? Do you need an independent technical assessment for your investment decision?

Our due diligence includes:

For: Investors, banks, buyers, sellers, M&A processes

FEASIBILITY STUDIES

Before you invest, you should know: Does the project work? Is it economical? What are the risks?

We create feasibility studies for:

Our approach: No theoretical concepts. Each study is based on real experience from implemented projects.

CIRCULAR ECONOMY POTENTIALS

Systemically network existing technologies. Intelligently connect energy and material flows. Turn individual plants into regional energy centers.

What we optimize:

Example: A biogas plant not only produces electricity. It supplies heat for a greenhouse, CO₂ for fertilization, processed digestate as quality fertilizer – and thus becomes a regional energy center.

Result: Higher profitability through additional revenue streams, lower CO₂ footprint, stronger regional anchoring.

TURNKEY CONSTRUCTION

We build plants that work.

My range of services:

Special feature: German technology, German quality for plants that run for decades.

REFURBISHMENT & REPOWERING

Many biogas plants are technically outdated or are running far below their potential. Targeted measures can significantly increase performance.


What we refurbish:

Our approach:

Result: Often 20-30% increase in performance with manageable investments.

COMMISSIONING

The most critical moment of every plant: The first weeks after construction. This is where it is decided whether a plant reaches its potential – or causes problems for years.


The commissioning:

Important: We stay on site until the plant is running stably.

TRAINING

The best plant only works with a competent operator team. That’s why training is part of every one of our projects.


What we train:

Format: Practical, on site at the plant, with real examples from 20 years of experience.

COMPRESSED AIR STORAGE – 10 YEARS OF RESEARCH, ONE PATENT

We have been researching compressed air storage technology since 2012. In 2024, the patent for the spindle storage drive was filed.

Why compressed air storage? The energy transition needs storage. Not just batteries – we need mechanical storage for large amounts of energy over long periods of time. Compressed air storage is one solution.

Our innovation: The spindle storage drive significantly improves the efficiency and economy of compressed air storage. Details are patented.

Vision: Compressed air storage as a supplement to batteries – for industry, grid operators, large consumers.

METHANIZATION ON A LARGE SCALE

The mission: Convert CO and CO2 into high-purity methane using bacteria – on an industrial scale.

The technology: Uses microbiological processes to convert synthesis gas (CO/CO2) into methane. This allows us to produce high-quality methane from residual materials that would normally only be incinerated.

Applications:

HYDROGEN FROM RENEWABLE RAW MATERIALS

Hydrogen is traded as the energy carrier of the future. The question is: Where does the hydrogen come from?

Our approach: Hydrogen from renewable raw materials – regional, sustainable, independent of fossil fuels.

Projects:

Goal: Green hydrogen at economical costs – for industry, mobility, energy storage.

SAF – SUSTAINABLE AVIATION FUEL

Aviation is one of the biggest challenges of the energy transition. SAF (Sustainable Aviation Fuel) is the solution.

Our role: In 2025, Herbert Huber is the technical consultant for a feasibility study in Straubing for the production of SAF from biomass.

The concept: Produce aviation fuels from regional, renewable raw materials – without fossil fuels, without long transport routes.

Potential: SAF can replace conventional kerosene without the need to modify aircraft or infrastructure. This makes it the most realistic solution for CO2-neutral aviation.
