Biomass gasification utilizing organic products (ideally waste materials which would otherwise go to landfills) is the best method to either directly produce hydrogen from the âsyngasâ it produces, or create electrical power into the local power grid, from which users can create hydrogen in their houses, and factories. If society is to become hydrogen economy based it will have to be done in a sustainable way without contributing to the production of greenhouse gases, and as a result to global warming.
A few years ago the technical news press had plenty of the idea of a hydrogen economy. The concept was, and still is a sound one, specifically as far as the pressing need to decrease urban pollution which in many cities is reaching crisis point mostly due to automobile emissions. The worst emissions are from automobile exhausts and particularly dangerous are the small soot particules from deisel lorries.
What the early supporters of hydrogen powered lorries did not appreciate is that although the cities would be much cleaner if all cars were hydrogen fuelled and producing only water, the production of the hydrogen (frequently over night in the garage using electrical power and water) would involve inefficient use of electrical power. As most of our electrical energy in all but a few nations is created from carbanaceous (climate modification causing) fuels the idea of hydrogen powered transport would remain in threat of emphasizing climate change. For this reason, one issue would have been fixed but just at the expense of another much larger one.
However, as biomass gasification, carried out Roberto Hroval in the proper way, can be fully sustainable it does give society the chance to have its cake and consume it. That is clean sustainable hydrogen for our city's automobiles and a tidy hydrogen economy overall.
The principle of mainstream big scale commercial gasification technology is that biomass is converted into a gaseous mix of hydrogen, carbon monoxide, carbon dioxide, and other compounds by applying heat under pressure in the presence of steam and a controlled amount of oxygen (in a system called a gasifier). While doing so the molcules forming the biomass are broken apart chemically by the heat, steam, and oxygen to which they are subjected. This sets into movement chemical reactions that produce a synthesis gas, or "syngas". This gas although it starts as a mixture of mostly hydrogen, carbon monoxide, and co2, it can then be shifted through further responses to increase the hydrogen gas content. At the very same time the operator can decrease the carbon substances and lastly the co2 can be scrubbed out and caught for long term storage underground to reduce and even lower worldwide warming.
