“…For example, a LCA study concluded that hydrogen production through biomass gasification for electricity production for subsequent used in electrolysis system had 86% reduction in greenhouse gas (GHG) emissions, although it also had greater acidification impacts than hydrogen production through biomass gasification and subsequent steam reforming system [6]. This benefit and detriment identified for each process are results of LCA studies.…”

Abstract:Biomass gasification has the potential to produce renewable fuels, chemicals and power at large utility scale facilities. In these plants catalysts would likely be used to reform and clean the generated biomass syngas. Traditional catalysts are made from transition metals, while catalysts made from biochar are being studied. A life cycle assessment (LCA) study was performed to analyze the sustainability, via impact assessments, of producing a metal catalyst versus a dedicated biochar catalyst. The LCA results indicate that biochar has a 93% reduction in greenhouse gas (GHG) emissions and requires 95.7% less energy than the metal catalyst to produce. The study also estimated that biochar production would also have fewer impacts on human health (e.g., carcinogens and respiratory impacts) than the production of a metal catalyst. The possible disadvantage of biochar production in the ecosystem quality is due mostly to its impacts on agricultural land occupation. Sensitivity analysis was carried out to assess environmental impacts of variability in the two production systems. In the metal catalyst manufacture, the extraction and production of nickel (Ni) had significant negative effects on the environmental impacts. For biochar production, low moisture content (MC, 9%) and high yield type (8 tons/acre) switchgrass appeared more sustainable.

“…In case of H 2 production by steam reforming of biomass about 2.4 J is needed to generate 1 J of H 2 (Koroneos et al 2008). When cultivated biomass is used for this purpose life cycle emissions are unlikely to be better than in case of steam reformed methane (Huijbregts and Reijnders 2009).…”

There are unconventional fuels that may serve as near term major replacements for conventional mineral oil and natural gas. These include fuels from oil shale and bitumen, liquid fuels from coal, methane from methane hydrates, biofuels and the secondary fuel hydrogen. Here, these fuels will be reviewed as to their presumable stocks and life cycle wastes, emissions and inputs of natural resources. The unconventional fuels are usually characterized by a relatively poor source-toburner energy efficiency when compared with current conventional mineral oil and gas. Apart from some varieties of hydrogen and biofuel, their life cycles are characterized by relatively large water inputs, emissions, and wastes. The unconventional fuels shale oil, bituminous oil, coal liquids, and methane from methane hydrates are based on natural resources which are practically finite. This does not hold for biofuels, but the sustainable supply thereof is severely limited when large numbers of people also have to be fed. In view of the problems associated with unconventional fuels, there is a case to consider fuel-less replacements for many fuel applications.

“…Actually, biomass is one of the stages in the lifecycles of energy and carbon on the earth. There are plenty of biomass resources in every part of the world, making biomass energies available in almost every corner of this planet [22]. There are four main categories of biomass worldwide that could be utilized, including agriculture waste (crop straw, animal wastes, etc.…”

Abstract:Hydrogen energy systems are recognized as a promising solution for the energy shortage and environmental pollution crises. To meet the increasing demand for hydrogen, various possible systems have been investigated for the production of hydrogen by efficient and economical processes. Because of its advantages of being renewable and environmentally friendly, biomass processing has the potential to become the major hydrogen production route in the future. Membrane technology provides an efficient and cost-effective solution for hydrogen separation and greenhouse gas capture in biomass processing. In this review, the future prospects of using gas separation membranes for hydrogen production in biomass processing are extensively addressed from two perspectives: (1) the current development status of hydrogen separation membranes made of different materials and (2) the feasibility of using these membranes for practical applications in biomass-derived hydrogen production. Different types of hydrogen separation membranes, including polymeric membranes, dense metal membranes, microporous membranes (zeolite, metal-organic frameworks (MOFs), silica, etc.) are systematically discussed in terms of their fabrication methods, gas permeation performance, structure stability properties, etc. In addition, the application feasibility of these membranes in biomass processing is assessed from both practical and economic perspectives. The benefits and possibilities of using membrane reactors for hydrogen production in biomass processing are also discussed. Lastly, we summarize the limitations of the currently available hydrogen membranes as well as the gaps between research achievements and industrial application. We also propose expected research directions for the future development of hydrogen gas membrane technology.
