ENERGETIC USE
OF STRAW
FOR THE
PRODUCTION
OF
HEAT AND ELECTRIC ENERGY
Version 12
INTRODUCTION

The EU Renewable Energy Directive sets specific
regulations as well as indicative targets for each
member state.

The Kyoto Protocol on the reduction of emissions (esp.
CO2, CH4) requests signees to take qualified action
(country specific targets of emission reduction).

Worldwide efforts for the use of Renewable Energy
Resources (being „CO2 – neutral“)
Version 12
RENEWABLE ENERGY RESOURCES

A number of possible renewable energy (RE)
resources are at hand but not all of them can or
will be exploited depending on availability in the
respective locations or in technologies suitable.

RE from agricultural waste has been identified to
offer a potential readily available in most European
and Asian countries. So far only little use of straw
has been made for a number of reasons.
Version 12
THE EU MARKET OF RENEWABLE ENERGY RE

Most EU member states have already passed the national legal
framework to set targets of RE percentages and their time schedules.

Within the targets set most EU member states guarantee to the
producers of RE the marketability of RE (in addition, some EU member
states have set minimum prices per unit of RE).

By law grid operators are obliged to transmit RE in a non-discriminating
way at market prices and reinforce the grid – if necessary.

Penalties are in force both for not meeting the country target and for
power companies not purchasing RE (great variations among EU
member states).
Version 12
THE RE POTENTIAL OF STRAW

Straw as a waste product of crop production is theoretically available in
huge quantities. At present it is reused only to a limited extent for
various purposes.

The Lower Calorific Value LCV of straws is close to low quality brown
coal.

The logistics of collection, baling, and storing of straw is already
available and in operation.

The price of straw delivered to the power plant is lower than the price
of other biomass.

The use of straw for RE production will be an important factor to
stabilize the social structures of rural regions (additional revenues,
saving or creation of jobs, transition from agriculture to energy
production).
Version 12
REPORTED IMPEDIMENTS FOR STRAW AS RESOURCE

Straws typically show a low ash melting point, which can lead to severe
technical problems in the combustion chambers and boilers for steam
production (slagging, clogging, corrosion).

Emission limits could not be met.

Other agricultural wastes showing higher energy content have been the
preferred target of interest.

Commercial aspects and viability of straw as RE resource have only been
checked in selected few cases only.
… leading to the necessity of creating a comprehensive
„Concept for the Utilization of Straw as Renewable Energy Sources“.

KEY FEATURES OF THE CONCEPT

Optimization of Straw Logistics

Chemical Conditioning of Fuel

Adapted Burner Technology
Version 12
OPTIMIZATION OF STRAW LOGISTICS
MAIN SOLUTION

The standard procedure of producing straw bales
(squared blocks or rolled bales) shall be kept.

Storage of bales will continue to be open air or under open shelters and then
be transported to the power plant, where the bales are pelletized and
additives are added.
VARIANT SOLUTION

The Special Project Company may invest for and operate mobile pelletizers (or
briquetting machines), which visit the storages over an annual cycle and
produce high density pellets of straw (packed in big bags).

Big bags of pellets will be transported to the power plant of the Special
Project Company for combustion and production of RE.

CHEMICAL CONDITIONING OF WASTE STRAW

Prevention of ash melting in the incineration chamber
- chemical additives adapt the ash properties of straw
(increase of initial deformation / hemisphere / fluid temperature)

Deposits on heat transfer surfaces on boiler pipes and blocking of flue gas
passes will be prevented
- less formation of aerosols
- less corrosion and better efficiency

Lower emission levels
- immobilization of corrosive elements
Version 12
POWDER INCINERATION

Improved control of incineration process

Fewer movable components in the incineration
chamber

Improved control of corrosion and emission

AGENDA FOR
CONCEPT IMPLEMENTATION

HOLDING COMPANY ENOD sp.z o.o. (PL)
- ENOD d.o.o. centralizes the technical and
technological know-how and will sell key
components (design services, mobile pelletizers, core
technology plant equipment) to the individual project
at defined and fixed prices
- ENOD d.o.o. may need to undergo substantial
increase of equity capital for co-investment in the
national project
Version 12
AGENDA FOR
CONCEPT IMPLEMENTATION

SPECIAL PROJECT COMPANY
- Creation of a project related utility company
with full operational and commercial responsibility
- the Holding Company ENOD d.o.o. shall be a mandatory
minority shareholder. It shall receive a contract on
provision of know-how, services (consulting and design)
and supply of key technological components (powder
incineration system, mobile pelletizer etc.) against an
upfront payment and a current fee related to the kWh
produced.



The equity capital for the Holding Company ENOD sp.z o.o. shall be
shared and raised by the persons involved in the development of the
Concept and by one or more strategic investment partners.
The equity capital for the individual SPC Special Project Companies will
be raised by the Holding and other project individual investors (e.g.
local players, capital funds, strategic investors etc.).
Mid- to long-term commitment will be necessary.
Credits and loans will be highly necessary for the investments to be
implemented by the SPCs.
The warranty business for loans and credits will be of crucial
importance.
The availability of EU funds and subsidies need to be checked.
Future Emission Reduction Certificates under the Kyoto Protocol may be
ceded to creditors.
Green Certificates shall be commercialized – if available.
Version 12
INFORMATION SOURCES

Ample technical and commercial documents on the Concept and on the locations
are available for inspection (designs, market analysis, feasibility study, technical
descriptions, technical test reports, sensitivity analysis etc.)

This information shall be regarded as sensitive and confidential. Hence, a lawfully
construed agreement on confidentiality is imperative to be concluded between
the Holding Company and the potential co-investors for the Special Project
Company.
