Descripción: Resumo: It is well known that fossil fuels are the basis of the global energy market. The
amount of these non-renewable fuels is diminishing rapidly, and the world must find
alternative sources of fuels, and ways to make them feasible, in order to boost global
energy matrix in the next decades. Besides, the unbridled use of these fuels is harming
the environment and causing several problems, such as global warming, elevation of sea
levels and changes in entire ecosystems. Therefore, renewable fuels come in handy to
solve those problems. Biofuels, such as biodiesel and ethanol, are fuels derived
somehow from biomass. Biodiesel is produced through the transesterfication of
vegetable oils (products of grain processing) and ethanol through the fermentation of
sugars, such as sucrose, by microorganisms. Brazil, China, India and Russia are
expected to be amongst the 6 most industrialized countries in the world by 2050. As big
consumers of fossil fuels, they must be ahead of the production of biofuels, so they do
not need to depend on importing fossil fuels to continue growing. To measure the
technological development of those countries, patent information was used. Patents
filed by the 4 countries in both ethanol and biodiesel related technologies were searched
in the Derwent Innovation Index database, and analyzed individually, so that it was
possible to define the state of development of each country. China dominates filings in
both technologies, with 76% of filings in biodiesel and 74% in ethanol. Brazil comes in
second place in biodiesel related technologies with 15% and Russia stays is the second
best for ethanol related inventions, with 16%, even though Brazil has the biggest
capacity of biodiesel and ethanol production. This scenario is explained by the major
investments China has been making in Research & Development of new technologies
and the lack of culture from Brazilian companies, regarding protecting its inventions.
