Most important, reliable and no-regrettable measures are two move to renewable energies and energy saving/conservation. The concept of renewable energy is shown in Fig. 2. The trials of developments of new route to solar energies, for example production of polycrystalline silicon is important [9, 10]. The conversion of waste oil to fiiel has also been investigated [11]. The study on coal conversion is also developed to the biomass conversion study. 

The heatpipe reformer process concept for hydrogen-rich syngas production. (Reproduced from Karellas, S., Metz, T., Kuhn, S., and Karl, J., Online analysis of the tar content of the product gas from biomass gasification. Application on the BIOHPR. 14th European Biomass Conference Exhibition, Biomass for Energy, Industry and Climate Protection, ETA-Renewable Energies, Paris, 2005. With permission.)... 

The use of organic chemical hydrides on the basis of superheated liquid-film concept would, thus, make it possible to combine electrolysis hydrogen produced from renewable energy and by-product hydrogen recovered from various industrial processes, with the hydrogen demand practically for stationary fuel cells and hydrogen vehicles. 

In view of the finiteness of fossil energy products, accompanied by growing environmental problems, it is necessary to establish new, sustainable and future-oriented concepts for energy generation. The goal of sustainable development inevitably involves the exploitation of renewable sources of energy. Therefore, the European Union (EU) aims to double the proportion of renewable energy from 6% to 12% by 2010. Currently, around 4% (69 MtOE = 69 x 1061 of oil equivalents) of the EU s total...

Two-platform concept biorefinery Another form of biorefinery, which has been recently defined by the National Renewable Energy Laboratory (NREL) (www.nrel.gov/biomass/biorefinery.html) is the two-platform concept biorefinery. 

The major challenge for the utilization of biomass as renewable energy source in combined gasification/gas turbine plants is the efficient removal of tar and particulates from the feed gas of the gas turbine [11]. This is a another promising application of the concept of catalytic filtration, but the technical development is still in the laboratory state.
