Introduction Welcome to the Quick User Guide of the Offline Expert Feasibility Calculator for Small scale Digestion. This tool

lets you determine if a small scale anaerobic digestion installation (or biogas installation) is profitable.

Try for yourself. With the Offline Expert Feasibility Calculator for Small scale Digestion, you can calculate if a

biogas installation can make a profitable business case. With the tool, you can try different set-ups, scales,

optimise your installation and generate financial data that can be used in a business plan.

The tool is meant for farmers experts and biogas experts. Where the online Bioenergy scan

(www.BioEnergyFarm.eu) is developed to be used by farmers and landowners, the Offline Expert Feasibility

Calculator for Small scale Digestion is intended to be used by a trained consultant/experts.

The tool covers a broad range of installations and options. The tool is intended for farm scale biogas

installations. In effect, this means that installations up to a capacity of approximately 25.000 tonnes of biomass,

or 150 kWe electrical capacity of a CHP (combined heat and power generation), are all covered by the tool.

Furthermore, digestate treatment, heat delivery and biomethane production are all included in the tool.

No replacement for commercial offers. Although the financial data in the tool is based upon commercial offers

and laws of physics, the outcome of the tool is no replacement for commercial offers. The maker of the tool, the

project partners and the EACI can not be held responsible for the outcome of the tool.

1. Business case scenarios The Offline Expert Feasibility Calculator for Small scale Digestion includes four different scenarios. Each

scenario has a different business case. In the chapter, the different business cases are discussed.

1. Biogas

2. Heat

3. CHP

4. Biomethane

5. Digestate treatment

1.1 Biogas scenario

The main aim of the biogas scenario is to export the biogas, generated in the biogas plant, to a nearby energy

user, using a biogas network. The biogas is then converted at the end user into heat using a biogas boiler.

Because the biogas is exported, an additional boiler is needed on site, to generate heat for the biogas plant.

This boiler can be fuelled with biogas or wood chips. Revenues are created by substituting fossil heat production

with heat from the biogas boiler, and subsidies from the production of renewable heat.

1.2 Heat

In the heat scenario, the biogas generated in the biogas plant is converted into heat onsite, using a biogas

boiler. The heat is then transported to the end user, using a heat network. Revenues are created by substituting

fossil heat production with heat from the biogas boiler, and subsidies from the production of renewable heat.

The main difference with the biogas scenario is that heat, instead of biogas, is transported. A small heat network

(short distance to end user) can be cheaper than a biogas network and a separate boiler. However, a heat

network suffers from heat losses with increasing distance.

1.3 CHP

In the CHP (Combined Heat and Power) scenario, the biogas produced in the biogas plant is concerted into

heat and electricity onsite. The heat and electricity can then be used to compensate own energy use. Electricity

that is not use internally, is fed in to the electricity grid. Revenues are generated by substituting electricity and

fossil based heat, or by selling electricity to the grid. Exploitation subsidies can apply for both electricity and

heat which is utilized at the farm.

1.4 Biomethane

The biomethane scenario covers the upgrading of biogas to natural gas grid standards, by removing CO2 from

the biogas. The biomethane is fed in to the natural gas grid and sold to the gas company. Depending on the

upgrading technique used, electricity or heat is needed for the operation. Electricity will be bought from the grid,

whereas heat can be supplied with biogas or wood chips.

1.5 Digestate treatment

The digestate treatment scenario intents to avoid expensive transport and disposal of manure, and instead

produce fertilizers from the animal manure. Heat and electricity, necessary for the project, is supplied by a CHP.

2. Quick walkthrough The Offline Expert Feasibility Calculator for Small scale Digestion is an Microsoft Excel based tool, for Microsoft

Excel version 2003 or higher. For better graphical interaction, Microsoft Excel 2007 or higher is recommended.

The Offline Expert Feasibility Calculator for Small scale Digestion has 8 interface sheets. In the table below, the

content of each sheet is summarized.

1. Imprint General information of the tool and disclaimer

2. Interface_1 Main interface, where the biogas plant can be designed

3. Interface_2 Digestate treatment interface (separator, pasteurization etc.)

4. Interface_INV Investment overview

5. Interface_FIN Financial results

6. Interface_CF Cash flow overview

7. Substrates_manure Manure substrate database

8. Substrates_cosubstrates Cosubstrate database

In the following chapters, each interface sheet is discussed, using a case as example. This example is there to

lead you for the first time through the scan. All the basic tools and options are used and described. It is

recommended to do the same steps in your own Excel simultaneously. When finished you should be able to do

a scan at every farm that fits in the scope of the project.

For this example we used version 0.92 of the Offline Expert Feasibility Calculator for Small scale Digestion®.

Some visual details may be different in your version or for your country.

2.1 Farm details

For this example we will use a dairy farm from the Netherlands with 250 milking cows, 60 calves and 60

yearlings. To improve the biogas output of the plant, we will also discuss added some cosubstrates to the

digester. As co-substrates we add 70 ton of glycerine.

The farm is located in the Netherlands, so the tool will automatically apply the Dutch subsidy rules.

The farms new stable offers the possibility of producing fresh manure.

2.2 Imprint

2.3 Interface_1 Biogas plant design

Interface 1 is the main and most important interface sheet of the tool. This sheet contains nearly all input cells

of the tool and allows you to design the biogas plant for the farm. It is also the sheet where you can change the

Region of the biogas plant, the language and currency. Note that subsidy rules, energy prices, investments and

digester lay-out may be region specific. Please enter the country and region first!

On the print screen below the first rows of the Interface_1 are presented. For region you have to select the

country of the farm, because the country-specific parameters are used based on that selected country.

Language is only for the interface language. This has no further implications. Only when changing it later on,

some inputs from the dropdown menus are no longer recognized!

Sometimes region is important because of different tax or subsidy schemes or in case of climate differences

between regions in one country. The region will also be presented in the report.

The currency rate is default set for the project countries. The calculations are done in Euro, but when another

currency is selected, the interface is recalculated in that currency. Changing the default currency can be

important for comparison of cases between countries, or for example when presenting for a foreign bank with

other currency.

For name, address and email information about the farmer need to be filled in. This information is used in the

report and also stored at the project database.

Table 1 First rows of Interface_1

2.3.1 Livestock

After the general information about the plant we go to the most important data input screens: the livestock

information.

We start most left with the selection of species. Since the tool is focusing on farm-scale, manure based digestion,

most common farm species are presented. Those are Cows; Bulls; Pigs; Poultry and; Other. The chosen specie

defines what will show up in the next column.

2.3.1.1 ANIMAL TYPES

In our example we have a dairy farm, so we select Cows in this first cell. After that we move on to the next

column. We see that the dropdown menu only contains dairy animals: Dairy cows; Calves and; Yearlings. If you

change the first cell to bulls you see this second dropdown menu changes to: Bulls for meet and Young bulls

for meet.

In our example we have dairy, so we select in the 1st column Cows and in the 2nd column we choose Dairy cows.

Depending on the stable system one has solid or liquid manure. Most common for dairy farms in Western

Europe is liquid manure, so we select liquid manure. It is important to choose one of the options, because the

properties of different type of manure are completely different. Therefore there is no default option chosen by

the tool. You have to select one yourself!

The age of manure is important for the biogas potential. Older manure has a lower gas potential compared to

daily-fresh manure. New generation stables have low-emission stable floors with scrapers. Only with these

stables you can have daily fresh manure. In almost all other cases there is a cellar with a minimum quantity of

manure, so the manure will never be daily fresh before it enters the digester.

The farm in our example has milking cows, calves and yearlings. So we can complete this first screen like in

the picture below. Make sure you have these lines the same before we continue.

Table 3 Day-fresh manure prodiction

2.3.2 Numbers of animals

Now we have specified the animals we can add the correct numbers. Our example farm has 250 milking cows,

60 calves and 60 yearlings. If we fill these numbers in, the tables looks like the one below.

10 | Quick User Guide

You may have noticed that also grazing time needs to be specified. Animals are not necessary 24/7 in the

stables. About our farmer we know he let his cows in the meadow for 120 days a year and 6 hours per day. The

younger cows are all the time in the stables.

If animals are never in the field, we can let this open. Only if they are in the field sometimes, this has to be filled

in. This because manure produced in the field cannot be pumped in the digester.

The completed table for our farm looks like the one below. Right from the animal numbers there is also a table

for manure supply. This can be used when for example manure from the neighbor is also brought to this digester.

This is not farm-produced manure, so can be specified separately. Also costs for buying this manure can be

specified, also negative costs.

The brown cells are output cells that present the manure production of the farm. These numbers can for example

be checked with the existing manure bookkeeping of the farmer.

The last column is specific for organic farmers. By choosing yes or no nitrogen can be labeled as organic or

non-organic, what has consequences for digestate at organic farms.

For our example farm we see a total manure production of 7.276 ton per year.

2.3.3 Adding cosubstrates

Besides manure there is also the option to feed some co-substrates. Note that this tool is for mainly manure

with some adding of co-substrates. A calculation tool for co-digesters was developed in the former project

BioEnergy Farm, and is still available at the project website www.bioenergyfarm.eu, as ADPC (Anaerobic

Digestion Profit Calculator).

The adding of co-substrates is comparable to that of manure. There is a limited number of substrates in the

database.

In our example we add a 70 ton of Glycerin to the digester. Purchasing costs are about €100/ton. If you don`t

know the exact price, the tool give (if available) a price indication in the brown column. Be aware this number is

not used in the calculation, so you have to fill in a price in the Costs column.

If correct filled in, your table would look like below.

Table 6 Adding Cosubstrates

At the bottom of the table above there are some extra outputs. First the share of co-substrates of the total mass.

This is done because some countries have restrictions on this share related to the subsidy scheme. In the

Netherlands for example this should be <5% to apply for the manure digestion subsidies.

The other brown cell presents the needed land for the production of the co-substrates. This is only calculated

for crops like maize, corn, CCM, grasses, etc. This number is indicative, and based on average production rates.

This value is not used in further calculations.

2.3.4 Main characteristics biogas plant and utilization techniques

After you have selected the substrates, the main properties of the biogas plant are displayed on the right. Here

you can find the main characteristics of the biogas plant, input substrates, digestate output and the capacity

and production of the different utilization techniques for the biogas.

Table 7 Main characteristics of the biogas plant and utilization techniques (Biogas, Heat, CHP and Biomethane)1

Quick User Guide | 13

2.3.4.1 DIGESTER SIZE

The size of the digester (digester volume) is in principle based on the amount of substrates and the retention

time in the digester. This means that for the digestion of 8000 tons of manure (7921 m³), with a retention time

of 25 days, a digester with a useful nett volume of 543 m³ is required. Added other substrates with higher

retention times, will result in a larger digester; the retention time of all substrates is set to the highest retention

time of the substrates.

However, to avoid a too high ODM load, the ODM load is capped at 3,5 kg/m³.day. This means that when the

combined selected substrates exceed this load, the digester will be larger, so that the ODM load is 3,5

kg/m³.day.

You can manually overwrite the digester volume in the cell: override volume. Be advised that after you overwrite

the volume, retention time and ODM load are no longer controlled by the tool.

2.3.5 First results, optimal case

This table shows the results of the most optimal case, assuming that all energy generated by the biogas plant

is used at the farm to replace fossil fuel. This table is meant for reference. If the scenario’s in this case, with

default energy prices and default investment layout, is not profitable, it is not likely that the case will be profitable

at all.

Table 8 Overview of first results, optimal case

2.3.6 Storage

With the tool, you can include storage facilities for cosubstrates and digestate in the business plan. Depending

on the current storage facilities on the farm, you may want to include a different type of storage:

1. No storage

2. Only additional storage from adding cosubstrates

3. All digestate

The default option in the tool is option 2, only additional storage from adding cosubstrates.

Table 9 Storage

You can then indicate storage period, and the available storage on your farm, after which the tool will

automatically calculate the possible additional storage required. Please be advised that is a separator is

Main characteristics biogas plant and utilization techniques, you have already found the energy production that

needs to be substituted. Please select the energy sources used on the farm or at a nearby energy user.

If the amount of electricity that can be substituted is lower than the electricity produced in the CHP, the remaining

electricity is fed into the grid at feed-in tariff.

2.3.8 Energy supply to end user

In this part of the tool you can indicate the distance to the end user of the energy that can be substituted. This

means that piping to connect biogas plant and the end-user is automatically added to the investments.

You can also indicate if the export of energy is to third parties. The installation of piping though public area’s is

more expensive then though private ground, due to permits and planning permissions. Indicating third party

energy export, means including piping though public areas.

The complexity of the trajectory is an indication for the difficulty of the installation. The complexity of the

trajectory is [0] for pipes through open fields, and [1] for urban areas. Please specify the complexity for the

chosen trajectory. Default complexity is 0,5.

Table 11 Energy supply to end user

To be able to connect to the gas grid, for the feed-in of biomethane, piping should be added and the gas had to

be pressurized to the grid pressure. Please fill in the distance to the gas grid, the complexity of this trajectory

(default 0,5) and the pressure in the gas grid.

2.3.9 Feed-in tariffs and subsidies

The tool shows the default values for the exploitation subsidies and the feed-in tariffs of electricity and heat,

based on country specific information from the technical partners in the BioEnergy Farm 2 project. You have

the possibility to overwrite the values, using the green cells. Please use the unit that is prescribed.

The digester needs heat to operate. In the CHP and Heat scenario, part of the heat generated by the biogas

boiler or CHP, is used to heat the digester. In the Biogas and Biomethane scenario there is also heat required,

and you can choose to generate this heat using biogas or wood chips. Using wood chips means that there is

more biogas available to supply to the end user (biogas scenario) or to upgrade to natural gas and feed in to

the grid (biomethane scenario), possibly increasing the profits of the installation. Further there is the possibility

to overwrite the default wood chips price of your country.

Table 13 Selection of used heat source for the biogas and biomethane scenario

2.3.11 Flare

If the standard utilization technique is out of order, due to maintenance or a breakdown, the biogas storage in

the digester may not always be sufficient in size to cover to complete period. The ventilation of biogas (methane)

to the atmosphere may be more hazardous than ventilation of CO2 from the burned biogas. Therefore, a flare

is needed for long maintenance periods. In some countries, a flare can be contracted or leased for short periods,

whereas other countries require in the installation of a flare as standard.

If you want to add a flare to the investments, please select Yes here.

Table 14 Selection to add flare

2.3.12 Investment subsidies

Investment subsidies can be added to the tool in three (3) ways:

1. Adding a fixed subsidy on the investments

2. Adding a percentage of the total investments

3. Adding both a fixed subsidy and a percentage

Choosing the third option will result in a fixed investment subsidy that will not exceed the percentage entered in

the second line (e.g. the investment subsidy is €150.000 with a maximum of 50% of the total investment)

Heat production and transportation to nearby end-user

Electricity production and feed-in grid

Biogas upgrading to biomethane and feed-in natural gas grid

Avoid the expensive disposal and transportation of fresh manure by concentrating minerals

Principals Digester is heated with own biogas or other sustainable source (e.g. wood chips). Biogas is transported in biogas pipes to end-user at low pressure, where a biogas boiler of CHP is installed.

Biogas is converted into heat with a biogas boiler, heat is then transported to the end-used with a heat-network. Part of the heat is used to heat the digester

Biogas is converted into electricity and heat using a CHP. The electricity is fed in to the grid. The heat is partly used for the digester, the rest is dissipated using a chiller

Biogas is upgraded to biomethane using an upgrading technique. This biomethane is then fed into the natural gas grid.
