Environmental Impacts of Hydrogen

The additional environmental impact of hydrogen production from each of these pathways should be carefully considered aspects such as land use and NOx emissions should be evaluated. In parallel the following activities should start today, to have the respective technologies available. Furthermore if positive research results have been achieved, these pathways should be also demonstrated under the framework of a large-scale demonstration project ... [Pg.73]

However, the discussion on social impacts cannot only be limited on the propulsion system but must also include the production, transport, delivery and storage of hydrogen. (For more background information on the discussion of energy production and environmental impacts, see EEA, 2006b EPA, 2007 IAEA, 2007.) Important new impacts of hydrogen based on hydrogen production include ... [Pg.593]

Since FAS can be produced either from vegetable oil based or petrochemical-based fatty alcohol (Fig. 4.9), both types have been evaluated in a life-cycle analysis with a positive overall result for the natural based product. With vegetable-based fatty alcohol sulfate, the analysis starts with the harvesting of the oil fruits (palm kernels or coconuts) and their processing to isolate the desired plant oil. Subsequent transesterification and hydrogenation of the methyl ester intermediates lead to the fatty alcohols, which are finally sulfated to produce the desired product. Based on this analysis the environmental impact of vegetable oil based fatty alcohol sulfate compared with the petrochemical based product is as follows ... [Pg.88]

In the 1970s, a first serious energy crisis related to a sharp increase in the cost of fossil fuels led to a revival of interest in water electrolysis. This time the interest was focused on hydrogen as an energy vector that could possibly replace fossil fuels in the world economy The aim was twofold to become relatively independent of the influence of the oil market and to reduce the environmental impact of the... [Pg.235]

Reducing the environmental impact of fossil fuel and synthetic fuel production requires a massive production of clean hydrogen which water electrolysis technology can offer in water electrolysis, electricity enables breaking water molecules into its elementary components hydrogen and oxygen. In the case where the electricity is produced free of C02 emissions hydrogen is also produced C02 free. [Pg.300]
