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.

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
Danish Gas Technology Centre | 10 |
CONSULTANCY || MEASUREMENT || CERTIFICATION || DEVELOPMENT
In our laboratory we test gas appliances in relation to security, functionality, efficiency and environmental impact.
We work on research, deve- lopment 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.

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.
