A pyrolysis plant is an investment in four revenue streams: your own electricity, usable heat, biochar and CO₂ removal certificates. How large the investment turns out depends less on the plant itself than on how it is integrated into the site: fuel storage, heat pipes, grid connection, buildings and permits. This article shows what the plant brings in, which items arise in investment and operation, and which levers help to shape the budget.

What the investment brings in

Before looking at individual items, it is worth looking at the other side of the calculation. A Pyro-ClinX produces four values from woody residues at the same time:

• Electricity: 150 kW electrical (gross), around the clock, for your own use or for feed-in.
• Heat: max. 450 kW thermal, as process heat up to 360 °C for production, drying or heating.
• Biochar: around 75 kg per hour (dry matter), for your own use or for sale.
• CO₂ removal certificates: additional revenue if the carbon remains bound in its application and its whereabouts are documented.

On top of that come more predictable energy costs: fuel can be secured through your own residues or regional supply contracts instead of buying electricity and gas at fluctuating market prices. On request, pyropower takes over the biochar and certificates, so operations can focus on power and heat. How these returns add up in euros is shown in the article Economics of a pyrolysis plant.

Investment: the items at a glance

The investment in a pyrolysis plant consists of several blocks. The core plant with reactor, gas utilisation and power generation is the visible part. Alongside it are items that, depending on the site, are hardly noticeable or shape the budget.

For many businesses, what already exists does not need to be built again. With free hall space, an existing heating circuit and a sufficient grid connection, the investment focuses mainly on the plant and the fuel storage. On an empty plot, foundation, enclosure, pipes and grid connection are added.

Operation: running costs at a glance

Operating costs arise over the entire service life. An industrial plant is designed for 15 to 20 years of operation, so it pays to plan for them from the start.

Day-to-day effort is manageable. The Pyro-ClinX runs fully automatically, is monitored remotely and maintained in three service levels. On site, the main tasks are inspection rounds, accepting fuel and filling the biochar, tasks that fit well into existing routines. With your own residues, fuel purchasing is no longer needed, and often disposal as well.

Plan these items in from the start

A complete budget from the outset avoids later additions. These items belong in it:

• Grid connection and metering concept if power is fed in or supplied to third parties.
• Heat pipes to the consumer if plant and heat demand are not next to each other.
• Backup for maintenance periods, when a boiler or grid supply steps in.
• Biochar analyses and certification if the biochar is to be sold in line with the EBC standard or credited as a CO₂ sink.
• Time for permits and the grid operator in the project plan, so the start of revenues is planned realistically.

From indicative price to a reliable figure

Indicative prices, which we provide on request, give a first point of reference. A price per kilowatt alone, however, says little about pyrolysis plants, because plants deliver different products and are offered with different scopes of supply. More on this in the article Seven criteria for choosing a pyrolysis plant. A calculation becomes reliable when it is based on site data:

• quantity and moisture content of the residue
• electricity and heat load profile over the year
• existing infrastructure such as hall, heating circuit and grid connection
• permit situation at the site

At pyropower, this is the task of the pre-project phase. Using your company figures, it clarifies whether the system suits the site and when it pays for itself. A funding check is included at no extra cost. You receive a fixed-price offer for it, and if you then commission the plant, the cost of the pre-project phase is credited.

Conclusion

The costs of a pyrolysis plant consist of the plant, its integration into the site and operation over many years. They are offset by your own electricity, process heat, biochar and CO₂ removal certificates, and typical payback periods are between 3 and 8 years, depending on the site. Collecting all items early lets you compare offers on the same basis and quickly shows which levers work at your own site. Indicative prices and an initial conversation about your site are available on request. How costs and returns combine into a result is shown in the article Economics of a pyrolysis plant. The funding overview explains which programmes support the investment.

Frequently asked questions

What does a pyrolysis plant cost?

We provide indicative prices for the Pyro-ClinX on request. The exact investment depends on the site, in particular on fuel logistics, heat integration, grid connection and construction. The pre-project phase turns this into a reliable cost estimate with an economic assessment.

What does a pyrolysis plant bring in?

Electricity, heat, biochar and CO₂ removal certificates. How much of this arrives in euros depends mainly on energy prices, heat use and operating hours. Typical payback periods are between 3 and 8 years. The article on economics shows the levers.

What running costs arise during operation?

Fuel, maintenance and service, staff for inspection rounds and fuel acceptance, power for own consumption, insurance as well as measurements and records. The plant runs fully automatically. With your own residues, the fuel item falls because purchasing and often disposal costs no longer apply.

Is drying worthwhile for wet wood chips?

It is worthwhile if no other suitable fuel is available and heat for drying is on hand. The Pyro-ClinX processes wood chips with up to 25 % moisture content directly, and an optional module is available for wetter material.

Are several small plants more expensive than one large one?

Not necessarily. Several units at one site share storage, integration and planning, and while one unit is being serviced, the others keep running. Whether one or several units fit depends on the base load.

Which funding is available for the investment?

In Germany, payments under the EEG or KWKG are possible for electricity from biomass, the BEW for heat networks, the GRW for the investment depending on the region, and the KfW loan Renewable Energies Standard for financing. A funding check is included in the pre-project phase at no extra cost. The funding overview explains the programmes.
