Greenhouse Gas Balances of

Data

When conducting GHG modeling, it is important to study and assemble key data required for the study. This exercise enables the user to become conversant with the key parameters and familiar with the basic LCA aspects of the particular project. This effort also provides an opportunity to define the system boundaries and level of data needed.

There has been a great paucity of literature and relevant contacts or directory type of information in � data for renewable energy use such as bioenergy systems. GHG modeling studies require energy and GHG emission data. Collating this data can prove difficult, therefore the IEA Task38 and BIOMITRE seek to provide GHG bioenergy researchers at least a few key links to various databases.

BIOMITRE Tool


The BIOMITRE tool allows for a range of detail from basic (level 1) to highly detailed (level 3). Further information on this is contained in Section 6.1 of the BIOMITRE Technical Manual (see page 23), as well as information in the BIOMITRE User Manual (Appendix A).



GHG Emissions and Energy Data


IPCC Data Distribution Centre provides detailed data in the form of �Scenarios�. These scenario data can be viewed (and downloaded) following the links below:

Bioenergy Statistics and Data


Databases on Biomass Energy

BIOBIB - A Database for Biofuels

BIOBIB includes data of the ultimate analysis of the elements, the proximate analysis, the analysis of the minor and trace elements, data about the melting behavior of the ash and much more. BIOBIB does not only cover information about different types of wood, straw and energy crops but also waste-wood samples and biomass-waste-assortments of different biomass-treating industries (e.g. wood processing industry, pulp and paper industry, food industry). Currently the database contains 331 different fuels.

Phyllis Database

Phyllis is a database, containing information on the composition of biomass and waste. Phyllis enables you to make analysis data of individual biomass or waste materials available and offers you the possibility to obtain the average composition of any combination of groups and/or subgroups.

You can get answers on questions like:

  • What is the average sulphur content of wood?
  • What is the ash content of willow?
  • What is the average calorific value of chicken manure?

TERI ENVIS Database

The TERI ENVIS database broadly deals with all environmental issues with special reference to biomass application, climate change, environmental economics, environmental planning/policy, environmental laws and regulations, hazardous wastes and their management, pollution and control technology, renewable energy and environment, sustainable development etc. It also includes global environmental issues pertaining to other developing countries relevant to this region.

UN Wood Energy Database

The database includes statistics on both conventional and biomass energy commodities. The conventional commodities included in the statistics are coal (hard coal, lignite, coke, peat, hard coal briquettes and lignite and peat briquettes), petroleum (crude petroleum, LPG, aviation gasoline, motor gasoline, kerosene, jet fuels, gas-diesel oils, residual fuel oil), gas (natural gas, other gas) and electricity (hydro, thermal, nuclear). The biomass fuels included in the statistics are fuelwood, charcoal and bagasse. Data for each type of fuel and aggregate data for the total mix of conventional fuels are provided for individual countries as well as summarized into regional and world tables. There are altogether 38 tables in the statistics which include production and trade of biomass energy.

Conversion Factors


Conversion Factors

This is a quick-reference list of conversion factors used by the Bioenergy Feedstock Development Programs at ORNL. It was compiled from a wide range of sources, and is designed to be concise and convenient rather than all-inclusive.
