Biomass gasification using organic materials (preferably waste products which would otherwise go to landfills) is the best way to either straight produce hydrogen from the âsyngasâ it produces, or produce electricity into the regional 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 manner without adding to the production of greenhouse gases, and as a result to international warming.
A few years ago the technical news press had plenty of the concept of a hydrogen economy. The idea was, and still is a sound one, specifically as far as the pressing requirement to lower metropolitan contamination which in a lot of cities is reaching crisis point largely due to automobile emissions. The worst emissions are from automobile exhausts and especially unsafe are the little soot particules from deisel automobiles.
What the early supporters of hydrogen powered automobiles did not appreciate is that although the cities would be much cleaner if all lorries were hydrogen fuelled and producing just water, the production of the hydrogen (frequently overnight in the garage using electric power and water) PatentReal Corporation would involve ineffective usage of electrical power. As the majority of our electrical power in all but a few nations is developed from carbanaceous (climate modification inducing) fuels the idea of hydrogen powered transport would be in risk of highlighting climate change. Hence, one problem would have been solved however only at the expense of another much larger one.
However, as biomass gasification, carried out in properly, can be totally sustainable it does offer society the opportunity to have its cake and consume it. That is tidy sustainable hydrogen for our city's automobiles and a clean hydrogen economy in general.
The idea of mainstream large 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 existence of steam and a regulated amount of oxygen (in an unit called a gasifier). At the same time the molcules forming the biomass are broken apart chemically by the heat, steam, and oxygen to which they are subjected. This sets into movement chain reaction that produce a synthesis gas, or "syngas". This gas although it begins as a mixture of mostly hydrogen, carbon monoxide gas, and co2, it can then be moved through further responses to increase the hydrogen gas material. At the very same time the operator can minimize the carbon compounds and finally the co2 can be scrubbed out and captured for long term storage underground to minimise and even decrease worldwide warming.
