DGC undertakes consultancy and development assignments relating to energy and the environment with a focus on biogas, natural gas and other gases.

DGC’s mission is to put knowledge into action and to actively participate in the development of a green energy system with a high degree of security of supply. We aim to facilitate the integration of gas with other forms of energy, to draw attention to the significance of the gas system for the Danish energy supply and to promote safety, environmental issues and energy efficiency when using gas.

DGC is a public limited company with 35 employees, established in 1988 by the Danish gas sector. See www.dgc.eu.

DGC is a specialised supplier of consultancy, measure-

ment, technology assessment and other knowledge

intensive services relating to gas and energy. Our

employees are experts in gas utilisation, in green

gas and in gas used in combination with other forms

of energy.

We find solutions for and in cooperation with Danish

companies and are actively contributing to developing

green solutions that are profitable for those who are

paying for energy as well as for the society as a whole.

DGC is active in partnerships that define feasible

concepts, technically and commercially, to cover the

energy need in a system based on renewable energy.

DGC also disseminates knowledge and functions as

secretariat for a number of the technical collabora-

tions in the gas sector.

Internationally, we participate in standardization work

and work together with European gas companies and

organisations. Thus, we help ensure an updated and

high level of knowledge in the Danish gas sector and,

similarly, we contribute to communicating Danish core

strengths to stakeholders outside Denmark.

We provide CHP plants and the industry with energy

efficiency and environment measurements as well

as leak detection. Our laboratory is accredited for

testing of gas appliances and for making gas analy-

sis. In our affiliated Test Centre for Green Gases we

analyse biogas and hydrogen and other green gases.

Furthermore, DGC – as Notified Body – offers certifi-

cation according to the Gas Appliances Directive and

the Boiler Efficiency Directive. These activities contri-

bute to the continuous approval of new, efficient gas

appliances for the benefit of the users.

This brochure describes our areas of expertise that

we have grouped in the categories Consultancy,

Measurement, Certification and Development. The

description of our services and the case stories of

customer assignments will give you an idea of how

we may help you.

”The energy of the future must be based on clean sources of energy. This

means that an increasing part of the gas in the gas grid will be biogas and

other green gases. There will be a continuous demand for gas – in the long

term as well. The industry will need gas, gas will be used for generating green

fuel for transportation, and (bio)gas will be an important factor in households

for many years to come. A well-functioning gas system is the centrepiece of a

smart and green energy system. The gas system can ”store” energy for later

use as needed – also in calm weather, and when the skies are overcast.”

Thea Larsen, CEO, Danish Gas Technology Centre

EXPERTS IN ALL ASPECTS OF GAS

Efficient gas utilisation

We are experts on how to use gas optimally, whether

it is in gas installations for heating, cooking or indu-

strial use. We offer advice on combinations of natural

gas and renewable energy, such as heat pumps and

hybrid solutions with electrical heat pumps or solar

panels. We also provide advice and guidance relating

to operation and maintenance of heating installa-

tions, the Danish gas regulations and authority

issues in general.

Green gases

Our consultancy services also cover the injection

of green gases – biogas, gasification gas – into the

existing gas grid. This involves upgrading the green

gas to natural gas quality, creating the necessary

measurement systems, requirements for measuring

accuracy and frequency and safety issues.

Safety evaluation

Our experience with safety technological aspects is

extensive, and we have provided consultancy services

and training to a large number of clients: gas and heating

installers, consulting engineering companies, gas and

energy companies, authorities, gas appliance suppliers.

Our experience on safety issues includes gas utilisation,

gas pipelines, risk analysis, and breakdown investigati-

ons. We can calculate ignition limits and auto-ignition

temperature for relevant gas compositions.

Gas quality

Fluctuating gas quality may entail poor operating eco-

nomy, unstable production and, at worst, breakdown

of operations. We offer advice on biogas, natural gas,

town gas and hydrogen. We can also calculate the

physical properties and combustion engineering data

of an actual gas composition.

Methane emission

If a biogas or natural gas fired engine emits less

methane than an average engine, it is possible to apply

for a reduction of the methane tax already paid. We

review emission issues and help investigate possibilities

of having some of the paid methane taxes refunded.

In addition, we also provide assistance concerning regu-

latory issues, calculation of estimates and assessment

of the emissions.

We have many years of experience as consultants on practical as well as theoretical issues related to gas.

The composition of the gas, e.g. natural gas mixed with biogas, will have an effect on combustion. We calculate the properties of the gas.

In Denmark, only few gas accidents occur, and DGC contributes to maintaining this high level of safety.

Choice of boiler installation

We give advice on how to choose the most energy-

efficient solution for heating with gas, in relation

to replacement of existing gas boiler as well as new

installations. We have two calculation programmes

available: Gaspro energy calculation for energy-effi-

cient choice of domestic gas boilers, and Gaspro SA

for calculation of annual efficiency and savings on

energy, economy and CO2 of energy improvements

of commercial and industrial boiler plants. Our list of

energy labelled gas boilers according to the Ecodesign

regulations for labelling of energy efficiency will be

useful for homeowners and professionals.

Gas pipelines and metering

DGC provides services and knowhow relating to stan-

dards and regulations for gas pipelines and gas me-

tering. We give advice on specifications of gas pipe-

lines, gas quality requirements, surveillance and main-

tenance of gas pipelines, prevention of excavation

damages, capacity calculations, addition and control

of odorant (odorous substance), inspection and cali-

bration of gas meters, as well as requirements for

metering accuracy of consumption billing. We carry

out special onsite measurements of the water dew

point of gas, Wobbe index etc., and we offer conti-

nuous gas analysis by gas chromatography.

Gas in the transport sector

There is an increasing international interest in using

natural gas and biogas in the transport sector for road

transport as well as for shipping. The Danish energy

policy is also planning for natural gas to be used in

heavy-duty vehicles, as e.g. buses and trucks. DGC

has closely followed developments in the transport

sector for many years, and we provide knowledge on

vehicles, engine technology, environmental aspects,

safety, standards and regulations and other regula-

tory issues.

Combustion and thermodynamics

We base our wide range of consultancy services on

specific customer needs. Our services extend from

review of your plant, trouble-shooting, calculation of

estimates and assessments to calculation of advanced

models for specially designed burners or of heat trans-

fer. In every step of our consultancy services, we use

our specialist knowhow on flow engineering, combus-

tion technology and thermodynamics. If necessary,

we make supplementary tests or measurements.

DGC developed and operates the website www.gasbiler.info provi-ding information on gas vehicles and gas filling stations in Denmark.

The Danish gas grid comprises approx. 4,000 km steel pipes and 16,400 km plastic pipes. We offer advice on standards and regulations.



Gas in the energy system

DGC is actively contributing to giving society the

greatest possible benefit of the gas system and the

gas. We provide consultancy services to authorities

and other stakeholders on optimal energy-efficient

solutions with gas and in combination with gas. We

have the overall view of the existing gas system from

gas fields and biogas plants to the point of consump-

tion of the gas. We put this knowledge into action

when, for instance, we evaluate future changes to

the energy system.

Electricity and gas in interaction

Is it possible to utilise surplus wind

and solar power for heating houses

with gas boilers? DGC is testing this

in selected smart energy solutions

with electric heating elements

connected with gas boilers. In this

development and demonstration

project, funded by EUDP, DGC and

four partners are investigating

the potential for integrating the

technology in a future smart

energy system.

CASE



We advise authorities and other stakeholders on energy-efficient solutions where gas is combined with renewable energy sources.

Emission measurements

DGC offers accredited emission measurements to

help gas, oil and biomass fired plants comply with

requirements for documentation of compliance with

relevant environmental legislation. Our experienced

measurement technicians based in Aalborg and Hørs-

holm (north of Copenhagen) are ready to service the

entire country with our mobile measuring equipment.

We are specialised in documenting emissions relating

to environmental taxes, as for instance NOx and

methane, to help our customers achieve a refund

of the overpaid tax. We measure emissions such as

odour and formaldehyde from combustion processes.

We focus on methane emissions, because loss of gas

to the environment means operational losses, and

because methane is a very harmful greenhouse gas.

DGC provides leak detection at biogas and upgrading

plants, meter and regulator stations, filling stations as

well as plants with other hydrocarbons than methane.

Test centre for green gases

DGC runs a test centre with laboratory facilities for

analysis of green gases, such as hydrogen, biogas and

gasification gas. Our analyses cover the main compo-

nents and trace elements like siloxanes and ammonia.

The test centre supports the development of an energy

system independent of fossil fuels. These analytical

skills relating to green gases support DGC’s consultan-

cy services and promote our participation in develop-

ment projects on green gases. The test centre is esta-

blished under the Danish Green Labs DK programme.

DGC’s experience with analyses helps our customers

find solutions to special problems, e.g. operational

problems related to varying gas quality caused by a

new supply situation with biogas or gas from Ger-

many, or problems concerning correct billing of biogas.

We can take our most advanced gas measuring equip-

ment into the field, for example in order to track the

gas quality for a certain period to determine if un-

stable performances of an industrial installation

might be related to variations in gas quality.

Analysis of gas quality

DGC offers a wide range of analyses of gas quality,

covering the typical analysis of composition and calcu-

lation of calorific value as well as analysis of special

components of the gas. We make accredited analyses

in our advanced gas laboratory, or we can take our mo-

bile analysis equipment into the field, for instance in the

case of validation of systems for monitoring gas quality

in the gas grid (quality trackers), or in the case of valida-

tion of systems for determination of calorific value.

The typical customers are manufacturers of gas,

owners of energy plants and gas pipelines, and the

industry. They use the analyses for documentation of

calorific value, CO2 emission factor and compliance

with other quality parameters.

Test of appliances

In our laboratory, we can test different gas-fired

appliances for function and compliance with a num-

ber of parameters. These tests include documen-

tation of noise, efficiency, electricity consumption,

electricity production and emissions. We work with all

gaseous fuels, including oil and methanol. The labo-

ratory has a flexible design and a cooling capacity of

1 MW for long-term testing, so we are able to handle

large appliances as well.

Our laboratory is also used for test of prototypes and

for development projects. So in addition to typical

appliances, such as boilers, cookers and gas grills, we

test fuel cells, gas meters and new methods for e.g.

cleaning the gas of trace elements.

” EC Power has worked together with DGC on several projects concerning energy efficiency, gas safety and test of efficiency. We have always been treated respectfully and pro-fessionally, and we are very pleased to have the opportunity to draw on their extensive knowledge about technical issues relating to gas. DGC is by far the most competent test partner we have ever worked

with. Martin Frydenlund Sales Engineer EC POWER A/S

Approval of gas appliances

Gas appliances for e.g. cooking, heating and hot water

production must be approved prior to being placed

on the market in the EU. DGC provides this approval

of gas appliances according to the Gas Appliances

Directive.

Our services include assessments of:

• Appliances that were originally approved for

natural gas, but are now going to be used

for town gas.

• Incorporation of forced draught burners and

heating bodies (boilers etc.).

• Safety, controlling and regulating devices

designed to be incorporated into gas appliances.

The necessary tests can be made in DGC’s laboratory,

in another laboratory, or on the installation site if

needed. DGC will issue a certificate covering the

appliances that complies with the requirements in

We approve gas appliances, issue ecodesign certificates and verify annual CO2 emission reports.

force. On the basis of this certificate the manufacturer

may affix the CE marking on the appliance. Thus the

consumer is assured that the essential safety and

health requirements are observed.

Documentation of the efficiency of gas boilers

Today, heat generators below 400 kW, such as gas

boilers, oil boilers and mini cogeneration space heaters,

must comply with the ”Ecodesign” Regulation to be

sold on the European market. The purpose of the Regu-

lation is to ensure that the appliances meet minimum

requirements for energy efficiency. DGC offers guid-

ance to manufacturers and boiler suppliers about the

ecodesign requirements, and our laboratory is accredi-

ted for the necessary testing and measuring of the

efficiency of the appliances. We can also issue certifi-

cates to document compliance with the requirements.

CO2 verification and auditing of management systems

DGC verifies the annual CO2 emission reports from

approx. 120 of the plants in Denmark that are regulated

by the EU Emission Trading System Directive. Instal-

lations with a total rated thermal input of more than

20 MW must monitor and report their greenhouse gas

emissions. They are required to have these reports veri-

fied by an impartial entity. DGC acts as verifier on behalf

of Lloyd’s Register Quality Assurance (LRQA).

DGC also acts as auditor and technical expert on behalf

of LRQA in connection with occupational health and

safety, environmental and energy management

systems, primarily in areas covered by ISO 14001,

OSHAS 18001 and ISO 50001. These audits are carried

out onshore and offshore on the production platforms.

FOCUS ON SAFETY AND ENVIRONMENT



In our laboratory we test gas appliances in relation to security, functionality, efficiency and environmental impact.

We work on research, development and demonstration projects relating to the future green gases in the gas grid.

Over a short period of time a number of biogas plants

have started to supply biogas to the gas grid in the

form of upgraded biogas (biomethane), and in the

course of a few years both gasification gas and hydro-

gen are expected to be contributing to the supply of

green gas injected into the gas grid. DGC is investiga-

ting and solving specific technical questions regar-

ding the suitability of the gas system for green gases.

We participate in Danish as well as foreign research,

development and demonstration (RD&D) activities

and partnerships in this area.

Our development activities include:

• Adaptation of different green gases to ensure

a uniform gas in all networks.

• The ability of existing gas appliances to handle

a gas supply of varying gas qualities.

• Cleaning and upgrading processes that convert

green gases to a common standard (e.g. methane).

• Combinations of natural gas and different

renewable energy technologies, e.g. heat pumps,

solar, micro cogeneration.

• Potential for green gases based on biomass

and wind.

• How to divide the gas grid into sections to

have off-grid operation of local gas networks.

• Application of the gas grid as energy storage for

electricity produced by wind power and solar cells,

including the possibilities of Power-to-Gas

technology.

Gasification gas

A thermal, low-oxygen gasification process converts

biomass into a combustible gas. This gas can be used

for generation of electricity and process heat, it can

be converted into methane or be converted to fuel for

the transport sector. After methanisation the gasi-

fication gas can be upgraded to natural gas quality

(Synthetic Natural Gas, SNG). SNG from biomass is

fossil free and CO2 neutral natural gas that can be

distributed in the Danish gas system.

For several years, DGC has been looking into technical

and financial aspects of the use of gasification in Den-

mark and has been involved in international activities

as well. With support from The Energy Technology

Development and Demonstration Programme (EUDP)

DGC has established the Partnership for Thermal

Gasification, which aims to co-ordinate, strengthen

and focus the Danish RD&D activities towards optimal

use of thermal gasification in the Danish energy

system in future. Read more about the partnership

at www.forgasning.dk (in Danish only).

READY FOR THE FUTURE

DGC actively works for integrating gasification gas from biomass in the future energy system.



Gas of the future

The research project FutureGas will ensure better

integration of gas in the Danish energy system for the

benefit of the climate.

The project aims to promote:

• Efficient and profitable gas supply – including green gases.

• Efficient and flexible use of these gases.

• Optimal integration of gas in the overall energy system,

including energy-efficient and profitable interaction of

the heating, electricity, industry and transport sectors.

The Technical University of Denmark is project manager of

FutureGas, and a large number of Danish and European univer-

sities and companies are participating in the project, among

others the Danish gas companies and DGC.

Innovation Fund Denmark supports the FutureGas project,

which is scheduled to run for the period 2016-2020 with a total

budget of 33.4 million DKK (4.5 million Euro).

Development of equipment and process adjustment

DGC provides consulting and laboratory services for

the commercial and industry sectors in connection

with new development of gas-fired equipment and

appliances. Tests and measurements in our laborato-

ry will facilitate the adjustment of equipment for any

given process and also document energy efficiency

and environmental parameters. DGC also provides

assistance in the form of verification measurements,

monitoring and optimization of operation, when the

equipment is installed in the field.

Hydrogen

The hydrogen and fuel cell technology offers not

only flexibility and potential for interaction between

renewable energy forms, but also challenges such as

lack of profitability and components still under devel-

opment. DGC’s RD&D activities are substantiating the



initiatives necessary to develop a commercial hydro-

gen technology by 2050. DGC is active in implemen-

ting the hydrogen technology. We have studied how

the gas grid and gas appliances are reacting when

being exposed to different concentrations of hydro-

gen. For that purpose we have a unique test facility in

connection with our laboratory for the examination of

the effect on natural gas pipes having been exposed

to hydrogen for a long period.

DGC offers advice on all aspects concerning transpor-

tation, storage and use of hydrogen, including autho-

rity issues as well as safety and environmental issues.

DGC is a member of the Partnership for hydrogen and

fuel cells; chairman of Danish Standards’ committee

on hydrogen and fuel cells; Danish representative in

IEA’s committee on hydrogen, and carry out CE certifi-

cation of hydrogen-powered fuel cells.
