The Danish Energy Agency and Energinet, the Danish transmission system operator, publish catalogues containing data on technologies for energy carrier generation and conversion.

The catalogue presents technologies for generation and conversion of energy carriers. In particular: production of hydrogen by means of electrolysis, biofuels from biomass and production/upgrade of biogas/syngas. Most of the process are characterised by multiple inputs and multiple outputs, which include for example different fuels/feedstocks, electricity and process heat (recoverable or lost). Upstream and downstream processes are not included - the datasheets do not provide information on prices for fuels, environmental impact from fuel procurement, or the economic consequences of the substitution of fossil fuels with liquid fuels produced from biomass. The main purpose of the catalogue is to provide generalized data for analysis of energy systems, including economic scenario models and high-level energy planning.

The Coordinating Research Council, Inc. (CRC) is a non-profit corporation supported by the petroleum and automotive equipment industries. CRC operates through the committees made up of technical experts from industry and government who voluntarily participate. CRC’s function is to provide the mechanism for joint research conducted by the two industries that will help in determining the optimum combination of petroleum products and automotive equipment. CRC’s work is limited to research that is mutually beneficial to the two industries involved. The final results of the research conducted by, or under the auspices of, CRC are available to the public.

The Global Renewable Fuels Alliance (GRFA) is a global biofuels federation representing over 90% of the world’s renewable fuels production from 45 different countries.

The objective of this project, undertaken by (S&T)2, was to estimate the global GHG emissions reduction achieved through the production and use of biofuels. This work was first undertaken in 2009 and much has changed since then: biofuel production levels are higher, biofuel production processes have become more efficient and more is known about the GHG emissions of fossil fuel systems.

The European Commission's DG ENER develops and carries out the Commission's policies on energy.

The overall objective of this project is to provide information about the lifecycle GHG emissions of fossil fuels used in transport based on collection of actual data to the extent possible. The considerable information uncertainty related to the collection and elaboration of these data, as well as to the required regional/geographical specification of data has been tackled with the assessment of the range of the GHG emissions in the form of minimum, maximum and weighted average values.

The Danish Energy Agency has developed an LCA model for transportation fuels. This model includes all modes of transportation, cars, trucks, buses, trains, planes, and ships. It also includes a significant number of conventional and alternative fuels pathways. (S&T)2 developed the portion of the model that calculated the emissions associated with the materials in the vehicles, vessels, rail cars, and airplanes.

(S&T)2 developed a bill of materials for each of the modes of transport. Information on cars, trucks, buses, trains, ships, and planes was obtained. To the degree possible European data for the bill of materials has been used.
