Hydrogen from Biomass as an energy carrier has generated increasing interest in recent years. There are several different technologies to convert solid or liquid Biomass into a gas mix consisting of mainly hydrogen and carbon dioxide. Up to 30% of the energy stored in the product gas would originate from the sun by using solar thermal applications to source the conversion while the equivalent of 30% of the product gas would have to be burned using conventional approaches. This paper explains the principles of the main technical pathways for biomass gasification and shows their advantages and disadvantages especially in connection with the use of solar heat as energy source for the conversion reaction. Biomass gasification in supercritical water appears to be a simple and efficient and thus most convenient approach for solar thermal applications.

Charcoal Gasifier No 2

Hi Gasification Colleagues,

While charcoal gasifiers are as simple as desperation determines, the choices as to how they are designed is very much a factor of applied knowledge, using the materials that might be available. In the main, we will only be using components made of steel, and using basic welding equipment for assembly.

What is not discussed in literature on the subject of gasifier design, is the philosophy behind the design, and the phenomena created by that design. It is very clear that far to many people are locked into a mind set of chemical equations, and mathematical calculations before first being able to creating the correct phenomena to achieve the desired results.

Hi Gasification Colleagues,

Back in June, I promised to give you some basic lessons on how to make a charcoal gasifier, and to explain some terminology. This is for those who understand nothing about gasification in a practical sense, so should kick start those with less ability or resources. It does not cover gasifiers that use raw biomass.
