1. The Danish Energy
Technology Catalogues
General concept of a energy technology catalogue, the
Danish experiences in developing energy technology data
catalogues and how it is used

2. Outline of presentation
• Why common energy data
• What is the Danish Energy Technology
catalogue?
• How is it made?
- focus on approach for making technology
catalogue – not on specific technologies
July 19, 2017Danish Energy Agency Page 2
3. What is the Danish Energy Technology
catalogues?
• data sheets containing primarily structured,
quantitative data on status and projection of
development of costs and efficiencies and
other technology specific data.
• Data sets for e.g. 2015, 2020, 2030 and 2050
• Qualitative data descriptions
Public available
July 19, 2017Danish Energy Agency Page 3
4. What can TCs be used?
July 19, 2017Danish Energy Agency Page 4
• Analysis of energy systems, including economic
scenario models and total system energy planning.
• Simpler analysis of energy technologies, comparative
analysis
• Common reference point for calculations
-"Official" data on energy technologies that "all"
stakeholders can agree on. A kind of best estimate.
• Should not be used for projection and design of specific
energy installations /plants
5. Examles of used by DEA
• ”Energy scenarios for 2020,
2035 and 2050”
• Danish Energy Outlook
• TIMES-model
• …
-the backbone of many of our
analyses

8. The purpose of the TC method to
make energy technology data
Technology data that can be used for
comparisons of different energy technologies
that is general accepted of high quality and
made in a transparent process and
To ensure that the different groups working with
energy models in Denmark use the same
technology data July 19, 2017Danish Energy Agency Page 8
9. Purpose of Danish CT
To ensure fair competition between the
different technologies in analysis and
scenarios
to make it easier to compare results from
different energy models.
July 19, 2017Danish Energy Agency Page 9
10. Guidelines/Instructions
July 19, 2017Danish Energy Agency Page 10
To ensure consistency and comparability of data for
different technologies and the consistency of the
qualitative chapters and the transparency of the data .
- Detailed definitions of the parameters e.g. what is
included in the efficiency, in the investments cost, in
O&M cost, at what temperature is district heating
delivered and returned.
- How to write the qualitative sections
The relatively detailed guideline should also help the
model makers on how the data could be used in their
model
11. Overview of categories of energy technology
data in the catalogues

/contracted
- National register /statistics
- Expert assessments
- National studies /surveys
- International studies/ /surveys
July 19, 2017Danish Energy Agency Page 15
16. Marked standard not BAT
Market standards (if established):
- performance and cost data of recent installed
versions of the technology in Denmark or the
most similar countries in relation to the specific
technology in Northern Europe for the 2015
estimates.
July 19, 2017Danish Energy Agency Page 16
17. “Bottom up metode” - braking down the
investment cost
example offshore wind
July 19, 2017Danish Energy Agency Page 17

The cost of one unit for larger plants is usually less than
that for one unit for smaller plants

• Cn = Investment cost of plant n (e.g. in million EUR)
• Pn = Power generation capacity of plant n (e.g. in MW)
• 𝑎 = Proportionality factor, typical value 0.6-0.7
The plants should essentially be identical, only significant
difference is in size
19. Energy efficiency
• Technical experts
• National register
• Data through international sources, e.g. IEA
• Evaluation in relation to national context.
July 19, 2017Danish Energy Agency Page 19
20. Notes
• Notes are made to add further detail to data
• Notes is important to ensure transparency –
especially if references not used directly

21. Data for 2020, 2030 and 2050
Prediction of future data
Aiming at no empty cells, prefer the same ”wrong”
guess
22. Data for 2020, 2030 and 2050
Prediction of efficiencies, few and not well
established methods
Two approaches:
• Expert judgements – especially for identifying
barriers
• Reference technologies giving upper and lower
limits
23. Data for 2020, 2030 and 2050
Prediction of costs:
Examples of methodes
• Simple learning curve (with fixed yearly
improvement)
• bottom-up approaches
• expert judgements

32. The process for making Danish TCs
1. Formulation of TC guideline
• to ensure uniformity of the descriptions of the different
technologies data and in some extent between technology
categories.
2. Making the first draft of the Data collection, writing the text
(Technology experts and )
3. Deep dive workshop with technology experts and stakeholders
resulting in a 2. draft
4. Public hearing of the technology chapters of the TCs
• to validate data and ensure acceptance
5. Revision of data and text
6. Publication
7. Updating – back to 1(or 2).
33. Improving data quality and comparation
Tools to compare between technologies and
with data from ”last” version in a systematic
way have been introduced ( kind of quality
assurance)
July 19, 2017Danish Energy Agency Page 33
34. Who is the best to make the TC
Energy technology experts (expert in the
specific technology)
Energy consultants(technical) using energy
models themselve
July 19, 2017Danish Energy Agency Page 34
35. The value of international foreign TCs
TCs can be used in other contexts, but:
• May not be accepted by stakeholders
• Costs of installations are likely to be
different
• Technology ‘preferences’ may differ
• May not include the relevant technologies
But a cooperation is seen as beneficial for all

38. Details of some of the parameters
-Environment in the data sheet
Harmful emissions to air:
• SOx degree of desulphuring (%)
• NOX (=NO2 + NO) (g per GJ fuel)
• PM2.5, P10, (g per GJ fuel)
Greenhouse gas emissions
• CH4 (g per GJ fuel)
• N2O (g per GJ fuel)
• BC (g per GJ fuel)
CO2 emission values are not stated, as these depend only on the fuel,
not the technology.
July 19, 2017Danish Energy Agency Page 38
39. Details of some of the parameters
- Operation and maintenance (O&M) costs
Fixed O&M cost (€/MW/year): e.g. administration,
operational staff, service agreements, property tax,
insurance.
Variable O&M costs (€/MWh): e.g. consumption of auxiliary
materials (water, lubricants, fuel additives), treatment and
disposal of residuals, spare parts
Fuel costs are not included.
