What methodology has been used for the capacities maps?

The current Capacity Maps estimate current public and corporate R&D investments in SET-Plan priority technologies in the EU. The approach used capitalises on existing information to the extent possible and combines this with an assumptionbased methodology to derive at a reasonable estimation of corporate R&D investments by technology.

- Data on public national R&D investments of EU Member States are generally taken from the International Energy Agency's RD&D statistics or the Eurostat GBOARD (Government Budget Outlays or Appropriations of R&D) database, complemented by information which has been directly provided by some Member States. However, it has to be noted that both the GBAORD and the IEA databases miss some entries at the technological level of detail needed, and only 19 of the EU Member States are covered in the IEA RD&D statistics, as the remaining Member States are not IEA members. Data missing for 2007 were filled with data from previous years if available or data taken from official national sources.

- Regarding the EU's public R&D spending, funds within the 6th Research and Euratom Framework Programmes have been taken into consideration. These programmes have been assessed on the basis of individual projects rather than budget lines, thus going beyond projects financed under the 'core' energy budget line 'sustainable energy systems'. An annual average of the commitments has been used for these multiannual programmes (2002-2006).

- As data on corporate R&D investment are sketchy, especially at the level of technological detail required, a novel approach for estimating them has been developed for the present assessment. For each SET-Plan priority technology, the number of key R&D investors has been identified. The overall R&D investments of these companies were mainly derived from their annual reports, largely via the 'EU Industrial R&D Investment Scoreboard'. A company's overall R&D investment has then been allocated to individual technologies based on the combination of publicly available information with expert judgment.
