EHN CR COMBUSTIBLES RENOVABLES, S.A. (EHN CR)
is the company having the mis-sion of leading every activity
on the biomass energy business of the EHN group. This includes
biomass combustion, biofuels and other related services, with
activities going from the study of new biomass energy alternatives,
fuel availability, biomass logistic systems, projects’
technical and economic feasibility, raw material handling
systems, development and promotion of renew-able fuels, research
and development on new business opportunities, etc. In particular,
one of the activities of the company is to assure the supply
of raw material to the biomass production plants: 160,000
tons/year of straw to the 25 MW power plant that the Group
owns in the village of Sangüesa, in the Spanish region
of Navarra, and also the raw material for the 30,000 ton/year
biodiesel plant that is being built in the village of Caparroso,
also in Navarra.
The company is 100% owned by Corporación Energía
Hidroeléctrica de Navarra, S.A. (the head of the EHN
group), and was created at the beginning of 2001. The company
has nowadays a staff of about 20 people, including a team
of 16 technicians with high expertise backed by the involvement
in many technical and research projects.
The group
EHN is an independent business group consisting of over
35 companies dedicated to the devel-opment, construction and
operation of renewable energy sources and to the provision
of services to other companies in the field. Its mission is
to become an international benchmark to demon-strate the technical
and economic viability of a sustainable energy model.
EHN was founded in 1989, and initially worked in the small
hydro sector, in which it has 21 power stations with 61 MW
of installed capacity. In 1994 it began its ambitious wind
energy development programme which by December 2003 consisted
of 52 wind farms with almost 1,500 MW. Of this figure, 650
MW belong to the group in Spain, France and Germany. The parent
company also owns a 25 MW biomass plant based on straw combustion,
and a 1.2 MW photovoltaic solar energy plant. It is also constructing,
through wholly owned companies, a biodiesel production plant,
and it also owns a wind turbine manufacturing plant for trading
its own 1,500 kW wind turbine.
Concerning EU biomass projects, EHN CR directly participates
in:
• Bioelectricity-crops (project coordinator). 5FP
demonstration project, aiming at developing and testing
optimum crops for power production at combustion plants.
• HIAL. 5 FP research project, aiming at studying
and reducing the content of alkali elements in the crops
used for combustion in power plants.
EHN also participates in the biomass field in the
following EU projects:
• Altener (project coordinator): “Study of
the supply of straw and wood for a biomass plant for the
production of 25 MWe of electricity” (ended in 2000)
• Thermie (project coordinator): “25 MW straw
fired, high efficiency power plant”. 4FP demonstration
project, for the construction of the Sangüesa biomass
fired power plant. (ended in 2002)
• Biodina (project coordinator). 5 FP demonstration
project, for the construction of a 30,000 ton/year biodiesel
plant and development of the biomass chain from field to
vehicle.
• Co-Production Biofuels. 5 FP research project, for
the research of an Integrated Biomass Utilisation System,
based on the fermentation of the sugars contained in the
crops for etha-nol production to be used as fuel, together
with the combustion of the crops’ remaining solid
fraction for power production.
Other EU projects of the group:
• Adcon-Demowind (project coordinator). 5FP demonstration
project, for the development of advanced control high power
wind turbines
• Anemos. 5FP research project, with the aim of obtaining
wind-meteorological prediction models able to esteem the
production of wind farms in advance.
• WEP I. Ecos-Ouverture project, DG Regio, which aimed
at studying and developing wind development plans in several
Central European Countries (ended in 2002).
• Dispower. 5FP research project, which aims at providing
solutions and results for the im-plementation of distributed
generation.
• ENIRDGnet. 5FP research project, aiming at creating
a network to promote and study the integration of renewable
energies and distributed generation.
• HyWays. 6FP research project, aiming at the development
and the detailed evaluation of a harmonised “European
Hydrogen Energy Roadmap”
The company is also involved in several national, regional
and local projects, of which the one undertaken for the
development of the first prototype of a 1,300 kW wind turbine
between 1999 and 2000 can be highlighted.
