Sustainable energy vectors

However, to overcome present barriers, sustainable energy vectors should be developed in a harmonized way, taking into account all possibilities and related technologies, and not be limited to one or few sources. For example, in the transportation sector, several technologies present great potential biomass conversion into biofuels, hydrogen fuel cells, hybrid engines and the exploration of metal... 

The authority behind this reference book is the I DECAT Network of Excellence and it is dearly divided into four parts covering fuel cells, hydrogen and methane storage, hydrogen and hydrogen vectors production and industrial catalysis for sustainable energy. 

Hydrogen technologies are mostly still in their infancy. They promise a second energy vector, in addition to electricity, that could allow renewable, nuclear and cleaner coal energy sources to be harnessed for a variety of purposes, most notably transportation. Reduced dependence on oil and natural gas has obvious and mostly positive implications regarding both sustainability and security of supply concerns. On the other hand, a significant amount of research is still needed, and short-term deployment is... 

If the co-produced CO2 is sequestered, this technology is currently the most efficient and green hydrogen production (see also Ref 7) and might, therefore, be the intermediate step towards a completely sustainable energy economy based on reversible energy vectors. 

The classical concept of object dissolves in so far the configuration space for the internal degrees of freedom is concerned. The material elements such as electrons and nuclei must be present to sustain quantum states, but locali-zability is not a requirement it may be a result of specific operators. The configuration space is an abstract mathematical space. Of course, one can force a representation as position vectors for particles. Consequently, one has to interpret the wavefunction. But again, Eqs. (3 and 4) demand amplitudes, energy gaps, and quantum numbers. This is spectroscopy of one type or another. The introduction of I-frames allows classical frameworks to be naturally incorporated.
