1 Summary

One of the aims of the Record Biomap project is to collect information about innovative

technologies, systems, devices and methods for an efficient biomethane production in small

to medium scale applications on the biomethane map (www.biomethane-map.eu). According

to the project objectives, the project team focuses on monitoring the biogas market for new

devices and solutions for both laboratory and semi-scale research, as well as on verification

of existing technologies that are a subject to development.

In the typical biomethane production system, the Record Biomap project team has identified

three main elements of the technological process. The development and improvement of

those three main elements (pre-treatment, digestion, upgrading of biogas to biomethane) will

significantly increase the technological and economic efficiency of small and medium

biomethane plants. On the basis of available literature, consultations with biogas operators

and the results of own studies obtained in the project EraNet “SE.Biomethane”, it has been

proved that the greatest progress has to be made in the field of substrate pretreatment

before methane fermentation. The pretreatment of substrates will ensure a higher

biodegradability of typical organic substrates used for biogas production and will enable

efficient use of biomass that without pretreatment is not technologically feasible or cost-

effective. Another equally important element of the biogas production is efficient methane

fermentation. The effectiveness of this very complex biochemical process is determined by a

number of factors, including the temperature, the method of mixing, the method of substrate

dosing, the organic loading, the retention time, the concentration of anaerobic biomass, etc.

Because of the process sensitivity and multiparametric dependence of its effectiveness and

stability, it is necessary to search for technological solutions of bioreactors in which the

fermentation is conducted. The third important element of the supply chain, as reflected in

the Record Biomap project, is biogas purification, which has a direct impact on the potential

of biogas for further energy use.

The wide goal of Record Biomap is to accelerate innovation in small and medium scale

biomethane production and therefore shorten the time of transferring the technological

solutions with the Technology Readiness Level (TRL) of 3 to 5 to a market. Overview of the

technological solutions with TRL of 3 to 5 will enable to identify research directions in the

areas covered by the project. Moreover, these technological solutions will be a basis for the

preparation of project proposals that can be conducted by cooperation between the science

sector and industry. This cooperation can be established through the platform created within

the Record Biomap Project. The focus on technologies with low TRL is intended because

such technologies require the biggest financial, analytical and technical support. Establishing

an accessible and open database of such methods, technologies and installations will allow

collecting and matching partners interested in participation in the development and

implementation of this type of technologies.

It should be, however, emphasized that technologies with a TRL of 3 to 5 are difficult to

detect and present. This is directly related to the fact that new and effective technological

and economical solutions are most often available from companies that have already



reached market readiness. It is often not in the interest of industry to disclose the concepts of

technologies that are still in the optimization stage, especially if their technical, technological

and structural specifications are not yet protected by intellectual property (patent

applications, patents, utility models). The companies disseminate those solutions and

technologies whose copyright and ownership rights are already protected and their

effectiveness is confirmed at least on a semi-technical scale. In this case, the database

created during the Record Biomap project is an additional place where the companies can

present their achievements and technological advances that improve the effectiveness of

biomethane production. This is also an important feature of the project, which will facilitate

associations between biogas plant operators and industry players.

At the present stage of the project, it has only been possible to obtain data related to

pretreatment, anaerobic digestion and gas upgrading with a current TRL of 3 to 5 from

research centers, institutes and universities. For this type of entities, the Biomethane Map is

a platform to exchange experiences and search for partners for further research, as well as

the development of new research projects.

This report is an update of Deliverable 1.6 which has been published in September 2016.

The template was updated with the description of the core and vision of innovation, R&D

needs for technology. The technology supplier also provided data basis for data list (market

ready stage of technology (based on test runs of current techn.), market ready stage of

technology (based on estimate), current level (TRL) of technology).The more details about

flexibility should be provided (Start-stop-flexibility, part load possibility, self-maintenance

possibility). Moreover in case of biogas upgrading technology the information about removal

of H2S was added.

Out of the 22 technology descriptions, 7 were related to substrate pretreatment, 9 to

anaerobic digestion and 5 to gas upgrading (Fig 1.)

Description of the technology/equipment:

The device for ultrasound disintegration of organic matter was developed by scientists

at the University of Warmia and Mazury in Olsztyn and the authors are looking for potential

investors willing to implement/develop the presented device. The purpose of the ultrasound

disintegrator is to increase the susceptibility of substrate to anaerobic digestion due to

disintegration of organic matter as a result of ultrasound-caused cavitation. The

disintegration of substrates with dry mass up to 5% is possible.




The device compared to existing solutions reduces the demand for electricity at the

same effectiveness. In this device, a significantly higher density of the introduced ultrasounds

in comparison to other solutions, improves the efficiency of the disintegration process.

Operation of the ultrasonic waves takes place almost at the whole flow through the device.

The device for ultrasound disintegration of the biomass (Fig. 1) consists of a cylindrical

tank (1) with an inlet channel (2) and an outlet channel (3) on a side wall. Inside the tank (1),

there are strings (4) fixed on two discs (5 and 6) that are located in the upper and lower part

of the tank (1). The top disc (5) is connected to the disintegrating ultrasound generator (7),

and the bottom disc (6) is connected with the instrument (8) that is used to pull the strings

(4). The substrate with dry mass up to 5% flows by the inlet channel (2) to the tank (1). During

the flow it contacts with vibrating strings (4). The conditioned substrate outflows from the

tank by the outlet channel (3).

The device is patented (Patent No. 213950, decision from 2012).

TECHNOLOGY


Cattle and pig farmers, Sugar beet farmers

Industrial food production


The functional principle of “High-Performance-Digester” (HPD) is patented in

EP2314666A1. Main purpose is the digestion of pure pig or cattle slurry under

mesophilic conditions. Nevertheless, it is also suitable for other organic

suspensions with low concentrations of volatile solids as well as for sugar beet

mono digestion.

One of the main problems in producing biogas from organic liquids with low

organic content (odm) is the small space-time yield. Therefore, there should be

the need of big digester volume to get sufficient biogas yield. However, this is too

expensive, also coming along with a big ecological footprint.

Yet it is possible to get a small digester volume by reducing the hydraulic

retention time (HRT) of the liquid substrate. Unfortunately, the doubling time of

methane forming archaea is in the range between 10 and 12 days. That means




HRT should be at least 12 days under optimal conditions to prevent washout of

these microorganisms.

Technical installations within the process, also can prevent washout of archae by

keeping the methanogenic microbes in biofilms or filter beds. The patented HPD

uses filter beds from organic substrates instead of plastics and internal

recirculating of digester medium. Thereby the HRT of liquid is decoupled from the

HRT of solids.

Filter bed layers

Additionally to the liquid substrate, one can feed a small amount of fibrous

materials like cutted straw. After starting the digestion process during some

weeks of succession, layers with different microbial populations and activities

evolve. Within the digester medium, controlled pumping processes support this

production of layers.

At the highest level the raw fibers with lowest density concentrate. In this region

preferably hydrolytic processes proceed, also preventing foam. Beneath this level,

smaller particles with higher density and surface exist, originated from semi-

digested straw. This is also the layer with high amounts of fermentation acids. The

subjacent zone contains the highest biological activity, forming a colonization

surface and a reservoir for any kind of microorganism. This layer filters the non-

digested solids as well as the slowly growing methanogens, keeping most of them

within the process and preventing washout with the liquid phase.

The liquid below this filter bed is the digestate and can be pumped out of the

process daily or hourly. Usually it contains the least concentration of organics.

Through decoupling of liquid and solid phase, the High-Performance-Digester is

able to reduce the HRT of liquids like pig slurry significantly (to one third).

Stability

The methanogenic process is very stable – despite considerable daily changes in

organic content (odm) of slurry. Because of cyclic operation, the whole digestion

system acts as a substrate buffer. Amount of biogas production and methane

concentration remain nearly constant.




Pre-treatment

It is possible to combine the HPD with the PRV technologies Wave-Box and the

Kombi-Hydrolysis.

Fig. 1: Principle of High-Efficiency-Digester (Patent EP 2314666 A1)

Operation

Feeding is done by nozzles, directly onto the (straw-) surface, generating a slight

rotation of the digester medium. The volume flow is a downstream, supported by

biological degradation and different densities. Active mixing by stirring and

pumping is reduced to minimum. Only cyclic pumping of liquid from the

undermost levels up to the surface again brings semi-fermented substrate and

micronutrients back to the active layers.

TECHNOLOGY


Operators of biogas plants, searching efficient technologies;

Farmers wanting to use slurry and manure for biogas production;

Food technology plants with organic residues like spent grain, marc, belly grass, etc.


Kombi-Hydrolysis and Wave-Box

PRV has developed both elements to enhance the disintegration of difficult

degradable organic substrates – making it available for biogas production.




Combining both technologies as a pre-treatment-system, the benefits of

separated hydrolysis processes and of ultrasound technology will be multiplied.

The Kombi-Hydrolysis integrates dosing of substrates, crushing, mashing and

feeding of the digester as well as biochemical hydrolysis. No other dosing or

crushing unit is necessary.

This synergistic technology treats especially fibrous and rough biomass

suspensions (grass, manure, etc.) which are generally difficult to digest. The

operator therefore remains independent of easy fermentable substrates of high

quality (e.g. maize). Preferably, a continuous recirculation flow from the digester

into the hydrolysis tank is processed by passing the ultrasound Wave-Box.

Cavitation effects (fig. 1 and 2) break down the biomass, therefore boosting

microbiological activity inside the Kombi-Hydrolysis. The result of these

intensified processes is a significantly increased biogas production (usually 10 to

25 %), achieved with small energy input.

The Wave-Box normally is directly connected and adapted to the Kombi-

Hydrolysis. Nevertheless, both are also easily attachable to an existing biogas

plant as stand-alone-devices.

The Wave-Box control system can be integrated into the biogas plant‘s control

system via a data interface.

Optimized operation - increased plant efficiency

The Wave-Box runs in automatic (standard) or optionally in manual mode. Cutting

pumps haul the pre-fermented substrate from digester or second step fermenter

continuously into the Wave-Box and from there into the Kombi-Hydrolysis. While

passing the ultrasound units (sonotrodes), pressure fluctuations inside of cells

produce enormous cavitation forces: The fibrous parts of the substrate and cell

walls break. The resulting disintegration makes any kind of substrate better

available, intensifies the digestion process and sets free a number of macro-

molecules destroying enzymes. By recirculating several times between digester,

Kombi-Hydrolysis and Wave-Box the materials which are difficult to ferment are

broken down gradually.




Increased methane yield also boosts CHP-power output. Alternatively, the

operator can maintain a constant biogas and power production, while reducing

expensive feedstock (i.e. maize). In addition, an increase in methane content

improves the quality of the biogas. The simultaneously induced lowering of the

viscosity achieved by the use of ultrasound also produces savings in the plant‘s

own power consumption.

Due to permanent recording and monitoring of the main process-specific

parameters, the plant operator is always able to operate the Kombi-Hydrolysis

with Wave-Box optimally.

Technology of Wave-Box: High-power ultrasound technology - breaking down

biomass through cavitation - the principle

Ultrasound is sound with frequencies beyond audible sound, i.e. from 20 kHz up

to the megahertz range. In aqueous media, ultrasound waves cause periodic

compression and extension of the water phase (fig. 1). High-intensity ultrasound

is necessary to tear apart water molecules during the rarefaction phase, which

results in the formation of microscopically small voids in the liquid. These voids

become bubbles filled with water vapour or gas. They grow in extension phases

and shrink in compression phases, until they implode.

This event is cavitation, a process under extreme (adiabatic) conditions. On a

micro scale, there is a pressure of 500 bar and a temperature of about 5,000°C.

Particularly large cavitation bubbles are produced within the frequency range

from 20 to 100 kHz; when these bubbles collapse, they cause extreme mechanical

shear forces. These forces produced by ultrasound are capable of destroying even

the most robust surfaces.




Fig. 1: Principle of cavitation caused by ultrasound

How it works - Effect on bacteria, algae and agricultural biomass

High-intensity ultrasound causes biomass to break down (fig. 2). The Wave-Box

ultrasound system first decompose agglomerations of biomass material at rather

low energy input (short sonication time). Further sonication opens up the biomass

cells, so that the cell contents escape and dissolve. This process releases enzymes

from the bacterial biomass. Hence the sonicated biomass is readily available as a

substrate for active microorganisms and is degraded better in a subsequent

biological degradation process.

The vision for this technology is to be used as a pre-treatment step before conventional

upgrading technologies or as a pre-treatment to our ash filter technology to reduce the

demand for ash. Another possible scenario is that it under certain conditions may be

possible to reach German L-gas specs with in-situ methane enrichment as a single upgrading

technology. Many vehicles are already approved for and fully capable of running on L-gas (Natural gas with a lower methane content

of down to 85%).



The main barrier is heat loss during desorption. Another challenge is that the in-

situ methane enrichment system is intimately connected with the digestion process and therefore has to be optimized on a case by

case basis.

and H2S so that it reaches vehicle fuel standard while at the same time stabilizing the




technology solve.) ash making it possible to use as a forestry fertilizer. The problem is that current biogas upgrading technologies are too expensive for

small scale application. The ashfilter technology is designed to be low cost and low tech in order to make economic sense at small

scale to fill that market space.


see for the future)

The vision for the ashfilter technology is twofold: 1. Upgrading to vehicle fuel at farm scale enabling farmers to move towards

energy autonomy; 2. Cleaning landfill gas from H2S using waste to energy (WTE) ash that has to be landfilled anyway. This would mean

reduce maintenance cost of co‐generation at landfills so that more landfill gas is beneficially used for energy generation rather than being flared or, worse, not even being collected.



The primary barrier is ash logistics. How to get the ash from the biomass or waste

combustion plant to the biogas plant and then back to the forest or landfill depending on ash quality. This logistic works great in certain vertically integrated forestry/agricultural

farms but we need to make the logistics work at a grander scale and be more generic.

Promising work is being conducted within this area and we expect to solve this problem.

The method is based on using CaO‐rich wood fuel ash utilising the principle of carbonation, i.e.

calcium hydroxide (Ca(OH)2) is reacting with CO2 under the formation of calcite (CaCO3). The

implementation of this method is relatively simple and uses a residue with a low alternative

value. Previous trials have shown a good capacity for removal of CO2 and H2S from the biogas

and stabilisation of the ash.

Hydrodynamic disintegrator

Hydrodynamic disintegrator, used in studies, consists of multifunctional rotor,

which was made according to Patent PL 214335 B1, rotating inside the tank with a

capacity of 25 L, driven by an electric motor with a power of 2 kW and a rotational

speed of n = 2800/min. The rotor is mounted on a shaft of bearing unit inserted

through the cover and the sealant to the interior of the tank, coupled with the

engine by the rubber-metal clutch. The inlet port is located at the bottom of the

tank and the outlet at the lid of the tank. The inlet and outlet are equipped with a




2" valves and connected by bypass with 2" valve to enable flowing of liquid and

omitting the tank. Disintegrator tank also has additional ½" connectors, equipped

with a temperature meter, manometer and valve for sampling.

After filling of the tank and running the disintegrator, substrate is pumped

repeatedly through the rotor due to centrifugal force. Liquid is drawn into the

tank, by the inlet port located in the axis of the rotor, and is processed flowing

through the chambers located closest to the outer edge, and then is expelled

outside the rotor. Flowing inside the rotor, through other channels and chambers,

liquid is subjected to the alternating high and low pressure, which at the

appropriate spin speed creates conditions for the formation and disappearance of

cavitation bubbles, which is destructive to the structure of biological material

(substrate). After a set time the motor stops the disintegrator and substrate is

replaced. After disintegration, the substrate is removed from the tank during

filling, as a result of displacement by new inflowing liquid.

Substrate introduced into the device is exposed to high temperature and high

pressure, and then a sudden decompression. In the final phase of disintegration, the

substrate is subjected to a vacuum. This results in the destruction of organic matter.

Sudden changes in pressure favor the destruction by causing cavitation. It allows to get a

better effect of biomass disintegration at lower cost for heating.

The device has a tank 1 with the heating system 2 and is equipped with an inlet

port 3 for the raw substrate and the discharge port 4 for the processed substrate, and the




gas pipe 5. The gas pipe 5 ends with a overpressure electrovalve 6 and a underpressure

electrovalve 7. After the underpressure electrovalve the pipe is passed, which is

connected to a vacuum tank 8 to the discharge port 9.

Operation of the device

The substrate is introduced into the inlet port 3 into the tank 1 and heated by the

heating system 2. During the heating, temperature rise and increase the pressure in the

tank 1. When the desired temperature and pressure are achieved, gases and steam water

flow through the pipe 5 and by the overpressured electrovalve 6 to the atmosphere.

Switching on and off the electrovalve 6, which runs periodically, until the pressure close

to atmospheric pressure is achieved. Then the underpressured electrovalve 7 is turn on,

which runs periodically, and gas and steam water flow into the vacuum tank 8. After

lowering the vacuum in the vacuum tank 8 and the underpressured electrovalve 7 shuts

off and at the same time by the discharge port 9 the processed substrate is discharged.

connected to automatic electrovalves on upstream and downstream of the reactor and

permits any change in the length of the phase, and thus the amount of energy supplied. The

inflow to the device takes place from the bottom, and disintegrated substrate flows into the

fermentation reactor (Fig. 4). The 40 L of the substrat is disintegrated at the same time.

Segments of the reactor are completly filled with disintegrated liquid without air phase that

could suppress the propagation of ultrasound. Cross-section of the reactor is 100 x 100 mm

and it has been chosen for industrial ultrasonic transducers with frequency of 23 kHz ± 2%.

TECHNOLOGY


Small biogas plant for livestock farmers


The solid substrates (i.e. manure) are collected at a disposal field in the direct vicinity of

the biogas power plant facilities. With the use of a self-propelled feeder, the substrates are

exported from the disposal field to a substrate pretreatment tank (SPT) once a day. Cattle

slurry is also discharged to the SPT. In the SPT, which simultaneously plays the role of a

hydrolyzer, hydration needs to reach ca. 90%. In the SPT, the substrate is mixed and

homogenized with a mechanical agitator mounted on the tank’s axis. Because of the SPT’s

volume and retention time, the tank simultaneously plays the role of a hydrolyzer. The SPT is

the site where the first or acidic phase of methane fermentation proceeds. Appropriate




temperature conditions are maintained in the tank with a heating system (thin-walled PCV

pipes mounted along the walls inside the tank). The increase in biogas production efficiency is

achieved through the use of the ultrasound conditioning process. To this end, a mixture of

substrates from the SPT is pumped by the existing pumping system so that it passes through a

set of disintegrators. The processed substrate is then returned to the SPT. Afterwards, from

the SPT reactor the substrates are fed to a fermentation tank (FT) with a rotary pump and

flow through a milling disintegrator. The FT is the site where the actual process of biogas

production proceeds. Methane fermentation is carried out in mesophilic conditions at ca. 35 o

C. A fermenter is heated with hot water circulating in a closed system between a heat

exchange system in a technical room and a system of pipes in the fermentation tank (FT) and

post-fermentation tank (PFT). Heat used for heating tanks in the biogas power plant is

produced from biogas combustion in a gas boiler. The fermentation tank FT is the site where

the exact processes of organic matter degradation and biogas production proceed. The bulk of

fermenting microbiota and substrates are kept suspended with the use of a mechanical

agitator. The agitator is mounted in the vertical axis of the tank with a reducer and a drive on

the tank’s dome. The mixture of digested sludge flows gravitationally from the fermentation

tank FT to the post-fermentation tank PFT, where complete fermentation and process

extinguishing occur. The post-fermentation tank PFT is also equipped in an agitating system,

but it is not heated. From the PFT, the digested sludge passes to the retention tank RT. The

volume of this tank ensures ca. ten-day retention of digested sludge. From this tank, the

digested sludge is discharged via gully emptiers to a sludge tank located outside the biogas

works, from where it is exported as fertilizer.

Biogas produced during methane fermentation is collected from fermentation tank FT and

post-fermentation tank PFT. Through a filter with a bog iron ore, biogas reaches the gas boiler,

where it is combusted, which results in heat generation. Biogas is accumulated only in the gas

zone of the FT and PFT tanks. The boiler is switched on automatically when pressure rises

above 10 mbar. Biogas accumulated in the gas zone of the FT and PFT tanks is combusted.

When the pressure of biogas drops to 5 mbar, the unit is switched off automatically and

remains in stand-by mode until the pressure in the gas installation again increases to the

appropriate level.

TECHNOLOGY


Technology for micro and small biogas plant.


Anaerobic digester is designed as the circulation chamber with a central baffle. The feedstock and

anaerobic sludge are stirred by a submersible mixer. As the digester works in a batch-mode, the fresh

feedstock feeding enforces the outflow of the fermented biomass.

It is planned to operate one-step anaerobic digester without separation of the hydrolysis and

methanogenic phases. After the start-up period, the reactor will attain a steady-state with the

equilibrium between individual groups of microorganisms involved in the digestion of organic matter.

Anaerobic digester is heated by water running in closed circuit between cogeneration heat

exchanger and coils placed around the circumference inside the digester. The temperature in the

reaction chamber is maintained at 35oC.

The digester is covered by a gable roof with biogas output. The tightness of the digester near the

feeding chamber is provided by a transverse baffle with its lower edge located below the liquid level. A

water valve is used to collect biogas that is subsequently purified to remove moisture and to

desulfurize. Then, biogas is introduced to the cogeneration system. Biogas is collected in the head-




space of the reactor chamber. Thus, the cogeneration unit must correspond to the production of

biogas. In case of cogenerator failure, the excess of biogas will be released into the atmosphere by the

water valve. In the absence of biogas, the control equipment switches the cogeneration system to

standby mode until the amount of biogas rises to allow a stable engine operation (0,05 bar).

The digestate leaves the digester by gravity flow through an effluent weir to the storage tank. The

digestate can be directly applied as fertilizer and soil conditioner for agricultural applications or

separated and additionally pretreated to discharge of the liquid fraction into the municipal sewerage

system.

The anaerobic digester is designed as a steel rectangular container with a reaction chamber of 50 m3

inside. The walls of the container are made of steel and covered by water proof coatings inside and

jacketed by mineral wool (optionally styrofoam) insulation with a thickness of 100mm outside. The

digester has a durable, rigid cover with flame and overpressure protection. The feedstock inside the

reaction chamber is stirred by a submersible mixer. Additionally, the tank should be equipped with a

sludge discharge knife gate valve. The reactor has an openable lid to allow the introduction of fresh

feedstock located on the shorter side of the tank.

Small- and medium scale agricultural enterprises, farms, industrial plants, and municipal wastewater treatment plants, where the production of raw biogas intended for upgrading into biomethane with biogas flow between 10 Nm3/h and 200 Nm3/h.


Based on world class inventions in the preparation of durable adsorbent

materials, NeoZeo has developed a cost-efficient upgrading solution to tap the

enormous potential source of clean biogas fuel: farms and small towns - the

biomethane supply of the future!




Raw biogas comprises a mixture of methane (CH4) and carbon dioxide (CO2) and small amount

of oxygen (O2), in addition to some minor components such as H2O, H2S, and siloxanes. These

components can be removed by NeoZeo’s equipment. NeoZeo's complete and integrated

Biomethane Production solution includes: preconditioning of raw biogas: e.g. removal of

impurities and moisture; desulphurisation; separation of CO2; and distribution of pure

biomethane to gas fuel stations.

NeoZeo biogas upgrading modules are suitable for small- and mid-sized flows of raw biogas

produced on farms and in small towns, where raw biogas flow is between 10 and 200

Nm3/hour. Larger biogas flows can be upgraded using NeoZeo' biogas upgrading design on a

skid or utilizing more than one module.

NeoZeo biogas purification process relies on unique adsorbent materials in combination with

Vacuum Pressure Swing Adsorption (VPSA) technology that are particularly applicable to

small-scale raw biogas producers - small farms and agricultural enterprises and small
