They think syngas from biomass can replace most of the natural gas used at lime kilns and pulp mills in BC. <BR/><BR/>I expect most of the problems of safely transporting syngas -- with minimal degradation of materials the syngas contacts -- to be solved within 10 years. But it will take 20 years to gear up biomass production to significant levels, unless the narcissist - elect and his quasi-fascist cohorts get with it.al finhttps://www.blogger.com/profile/13739269791915017382noreply@blogger.comtag:blogger.com,1999:blog-24847368.post-25973459237406055132008-12-19T15:19:00.000-08:002008-12-19T15:19:00.000-08:00Leakage and toxicity are not degradation.

Also, leakage issues have not prevented <A HREF="http://www.eere.energy.gov/hydrogenandfuelcells/delivery/current_technology.html" REL="nofollow">~700 miles of hydrogen pipelines from operating in the USA</A>. Toxicity hasn't stopped ammonia pipelines, either.<BR/><BR/>Production of bio-oil loses about 30% of the energy of the original biomass (most of which is required to run the process), and there are additional losses in any further conversions. Gasification has similar losses but the waste heat can be used for e.g. electrical generation. The key point is that conversion to bio-oil can be used for "stranded" biomass resources, while gasification cannot.<BR/><BR/>Torrefaction is between. It compacts and preserves the biomass while losing only about 10% of the energy. Torrefaction may be a more useful process if the specific chemical products in bio-oil are not required.Engineer-Poethttps://www.blogger.com/profile/06420685176098522332noreply@blogger.comtag:blogger.com,1999:blog-24847368.post-55703654317641203032008-12-18T01:37:00.000-08:002008-12-18T01:37:00.000-08:00It takes pyrolysis oil a number of months to serio...It takes pyrolysis oil a number of months to seriously degrade. It does not store well, but it can be transported.<BR/><BR/>Hydrogen gas is difficult to contain, and does not pipe nearly as well as hydrocarbon gases without significant leakage. The toxicity of carbon monoxide presents serious hazards for extensive handling.<BR/><BR/>It is important to give development of these resources the two decades generally called for, to deal with such problems.al finhttps://www.blogger.com/profile/13739269791915017382noreply@blogger.comtag:blogger.com,1999:blog-24847368.post-41261401743310403422008-12-17T10:03:00.000-08:002008-12-17T10:03:00.000-08:00Gasification products do not degrade, they are jus...Gasification products do not degrade, they are just too bulky to store and too energy-poor (~300 BTU/ft³ for both H2 and CO) to be worth piping very far.<BR/><BR/>Bio-oil does degrade over time, by polymerizing. This increases its viscosity, among other things.Engineer-Poethttps://www.blogger.com/profile/06420685176098522332noreply@blogger.com
