GEOTHERMAL ENERGY
Geothermal technology is at the very front as a possible supplier
of lasting and climate friendly energy supply of the future.
The very low operational costs and environmental impact of the plant are attributes that
makes geothermal plants are an interesting technology, both at a Danish national level and at a global level. AAEN has been involved in the development of geothermal
district heating in Zakopane, Poland since 1997 and is currently co-financing an expanding the
system, including a planned establishment of geothermal CHP, through the JI project Expansion and Development of Geothermal Energy (EDGE) Zakopane. |
NETWORK REGISTRATION & DRINKING
WATER
The supply of drinking water
is one of our most vital supplies and paramount to a healthy society. AAEN has both national and international experience in the development and management of drinking water systems such as for example the 3d network
modelling tool AQUIS. |

At I/S Skive District Heating’s site on Thorsvej 11 in Skive a faint
rumbling sound emerging from the large, newly erected building reveals
that the gas engine plants, which have been installed behind the
beautiful building fronts covered in pre-oxidized copper, are in
service. It is however not the gas engines that provide the largest
news value, but the plant that delivers gas to the engines. The gas
is delivered by on the world’s largest “fluidized bed" gasification
plants designed for gasification of biomass. Behind this accomplishment
lies a unique scope of developments that has been both comprehensive
and extensive, as the development of the gasification plant influences
all element of the CHP central including the building construction,
engine plant development and almost all other units connected the
plant. In return I/S Skive District Heating now has a unique opportunity
to meet the climatic challenges of the future. Read Article |
MERGER OF DISTRICT HEATING COMPANIES
Rising natural gas prices, stricter environmental legislation and a fluctuating population are all conditions that are challenging the operating economy for District Heating companies both in Denmark and abroad. As a consequence the shape of the de-centralized Danish District Heating sector is changing. District Heating companies have started to merge fusing companies and interconnecting District Heating networks. The sector is still de-centralized, mind you, but it is moving toward a de-centralization made up of grouped networks, where technical plants are shared and heat is distributed through transmission lines. Apart from financial stability, the mergers also provide new possibilities for the investment in alternative technologies and the utilization of alternative fuels. |

DISTRICT COOLING - THE NEW DISTRICT
HEATING?
The technical principal behind district cooling has been known for many years and the name of the technology pretty much says it all: District Cooling = District Heating, just in reverse. The technological and operations economic reality behind the term is however, more complex and is the main reason for why presently there are only a few district cooling plants in operation in Denmark. From the start AAEN has been involved with the establishment of the districts cooling plant for Loegstoer District Cooling, which is a newly formed daughter company of Loegstoer District Heating A.m.b.a. The plant is now in operation and utilizes CO2-neutral heat from the neighboring biomass boiler plants a process drive heat. |
JI & CDM PROJECTS
The project possibilities under the Kyoto Protocol include Joint
Implementation (JI) and Clean Development Mechanism (CDM) projects.
JI projects are environmental projects mainly established in industrialized
countries that have a quota registration system and procedures for
the transfer of emission rights. CDM projects, on the other hand,
encompass environmental projects mainly in developing countries,
which do not yet have a quota registration system or procedures.
One of the best known and widespread project technologies are landfill
gas plants, where the methane gas produced by the landfill site that
will otherwise be emitted into the atmosphere, is collected and burnt
for energy purposes, in order to save the atmosphere from a considerable
green house gas (GHG) burden. |

NET REGISTRATION & DISTRICT HEATING OPERATION OPTIMISATION
The piping network constitutes the largest investment for district
heating companies and is the crucial connection between production
and consumer. A detailed and through registration of the piping network
is the foundation of al renovation plans and energy optimization
plans for district heating companies. Heat loss in the supply system
constitutes a considerable part of the operation costs for the heating
plants. This loss can however be reduced considerably by the use
of modern net registration and optimization programs. AAEN are involved
in development projects, where network models and iteration programs
have greatly improved the control and reduction of heat loss. Therefore
large savings can be reached with programs like DFF-MAP Press. |
BIOGAS IN THE AUSPICES OF DISTRICT HEATING
The district heating sector has begun to show interest in including
biogas plants in their plant portfolio. This is mainly due to the
very good climate characteristics of the technology, as well as the
fact that the price for green electricity based on biogas is now
guaranteed at minimum 74.5 kr. / MWh. In spite of the fact that the
biogas plant industry has been standing very still in Denmark for
the last decade, the technology has still managed to evolve greatly.
Because of the long time operation experience that has been achieved,
the technical basis for obtaining stable and economic operation is
now much better than when the technology was first introduced to
the sector. AAEN is involved with various projects concerning the
implementation of biogas plants for the district heating sector,
where the biogas industry can benefit from the technical expertise
and experience, which the district heating companies possess, and
the economic safety the corporation structure of district heating
companies provides both for the biogas plant and the farmers involved. |

NEW BIOMASS BOILER PLANT
AAEN has worked with biomass boiler plants for the utilization of
wood pellets, wood chips and straw. Regardless of whether the plant
investments is brought on by an increase in capacity of an existing
boiler plant or of the establishment of whole new biomass boiler
plant, there are a lot of considerations to be made. Plant dimension
and choice of technology are important subjects, but in addition
include other areas, like the arrangement and building architecture
and future possibilities for the utilization of alternative fuels
can have grate advantages. Especially the last issue can have a larger
effect than first expected, since biomass is projected to become
a desired resource in the near future. |
TECHNOLEGY DEVELOPMENT FUNDING
The development of energy technology and systems is often a time
consuming and costly activity. At the same time it is crucial that
the development performed both in reference to export of energy technology
and in reference to the accommodation of the climate challenges.
There exists a wide variety of funding programs that supports the
development of energy technological, both in Denmark, e.g. EUDP and
Danish District Heating F&U account, and internationally, e.g.
the EU's Frame Program. AAEN has for many years worked with the application
for and administration of the funds from a wide variety of foundations. |

Landfill Gas (LFG) Plants can generate green energy from waste. When waste composting or incineration is not an option i.e. because of economical or structural barriers, gas production from waste disposal become an advantageous possibility for production of green energy with substantial environmental benefits. With a relatively simple technology, the gas is extracted, compiled and burned in a gas engine producing green electricity and heat that can be used as a district heating. AAEN has experience from numerous LFG projects both at home and abroad. LFG plants are an excellent technology for developing climate projects, such as JI and CDM, as the relatively low establishment costs coupled with the high environmental impact, generates a project concept that is applicable in most regions around the world. |
WASTE MANAGEMENT STRATEGY PLANNING
Denmark has a unique waste management system, where the main part
of the waste is utilized through recycling and energy production,
which benefits the environment and the society. In fact less than
10% of the waste is deposited and special care is given to toxic
waste. These results have been reached through both specialized collection
systems adapted to local conditions and through treatment systems
adapted to each waste fraction. In the light of experiences with
the development of waste manage systems in Denmark, AAEN has been
able to export this knowledge and has prepared and implemented systems
adapted to local conditions in Zakopane, Poland, among other places. |
