Comprehensive research and development strategies for such technologies are required, though. Such strategies should focus not only on development of technologies but also on long-term deployment and building the infrastructure and markets required for those technologies. Market development and international trade Biofuel and biomass trade flows are modest compared to total bioenergy production but are growing rapidly. Trade takes place between neighbouring regions or countries, but increasingly trading is occurring over long distances.
For many rural communities in developing countries such a situation would offer good opportunities for socio-economic development. Sustainable biomass production may also contribute to the sustainable management of natural resources.
Importing countries on the other hand may be able to fulfil cost-effectively their GHG emission reduction targets and diversify their fuel mix. The Barra Grande alcohol and sugar production plant in Brazil produces ethanol from sugar cane on a commercial scale Production of liquid and gaseous fuels from biomass Table 3 provides a summary of estimates for costs of various fuels that can be produced from biomass.
A distinction is made between performance levels in the short and in the longer term. Also, the environmental impacts of growing annual crops are not as good as perennials because per unit of product considerably higher inputs of fertilisers and agrochemicals are needed. In addition, annual crops on average need better quality land than perennials to achieve good productivities. Perennial crops can also be grown on marginal lands, thereby achieving other potential benefits such as soil quality improvement.
For countries where sugar cane production is feasible, commercially available technology allows for production of relatively low-cost ethanol. Ethanol production capacity based on sugar cane is increasing substantially in African, Latin American, and Asian e. Furthermore, better use of cane residues e.
The production of methanol and di-methyl esters or DME , hydrogen, Fischer-Tropsch liquids, and ethanol produced from lignocellulosic biomass offers much better perspectives and competitive fuel prices in the longer term, i.
Partly, this is because of the inherently lower feedstock prices and versatility of producing lignocellulosic biomass under varying circumstances. Furthermore, the advanced gasification and hydrolysis technologies under development have the potential for efficient and competitive production of fuels, sometimes combined with co-production of electricity [Hamelinck and Given that several regions of the world have inherent advantages for producing biomass including lignocellulosic resources and biofuels in terms of land availability and production costs, they may gradually develop into net exporters of biomass and biofuels.
Questions about Handbook Solid Biomass?
International transport of biomass or energy carriers from biomass is feasible from both the energy and the cost points of view. The import of densified or pre-treated lignocellulosic biomass from various world regions may be preferred, especially for second generation biofuels, where lignocellulosic biomass is the feedstock and large-scale capitalintensive conversion capacity is required to achieve sound economics.
This is a situation comparable to that of current oil refineries in major ports which use oil supplies from around the globe.
Very important is the development of a sustainable, international biomass market and trade. Proper standardisation and certification procedures are to be developed and implemented to secure sustainable biomass production, preferably on the global level. Currently, this is a priority for various governments, market players, and international bodies.
Questions about Handbook Solid Biomass?
In particular, competition between production of food, preservation of forests and nature and use of land for biomass production should be avoided.
As argued, this is possible by using lignocellulosic biomass resources that can come from residues and wastes, which are grown on non-arable e. Demonstration of such combined development where sustainable biomass production is developed in conjunction with more efficient agricultural management is a challenge.
However, this is how bioenergy could contribute not only to renewable energy supplies and reducing GHG emissions, but also to rural development [Faaij and Domac, ]. A wide diversity of projections of potential future energy demand and supply exist [IPCC, ].
Typically, scenarios are used to depict uncertainties in future developments and possible development pathways. Differences between the scenarios concern economic, demographic, and technological development and the orientation towards economic, social, and ecological values.
Handbook Biomass Gasification
The storylines denoted A1 and A2 are considered societies with a strong focus towards economic development. In contrast, the B1 and B2 storylines are more focused on welfare issues and are ecologically orientated. While the A1 and B1 storylines are globally oriented, with a strong focus towards trade and global markets, the A2 and B2 storylines are more regionally oriented. Figure 2 shows the total energy demand for secondary energy carriers such as transport fuels, electricity, gas, etc.
Clearly, the various scenarios show large differences in demand and energy mix, as a result of variations in population dynamics, and economic and technological development.
Total primary the presumed mix of fossil fuels, renewables and nuclear energy demand in varies between about EJ and 1, EJ.
As discussed previously, the total primary biomass supplies in could amount to EJ. This is conservative relative to the increased availability of primary biomass for the different SRES scenarios, shown in Figure 3. The circled lines depict the total primary energy demand per scenario, corresponding with the projected energy consumption data in Figure 2.
All scenarios project a gradual development of biomass resource availability, largely corresponding to the potentially gradually increased availability of land over time. This is up to double the current demand and a similar range to the expected demand in the SRES scenarios discussed above. Competing markets for biomass?
On the other hand, the versatility of biomass with the diverse portfolio of conversion options, makes it possible to meet the demand for secondary energy carriers, as well as biomaterials. Currently, production of heat and electricity still dominate biomass use for energy.
The question is therefore what the most relevant future market for biomass may be. For avoiding CO2 emissions, replacing coal is at present a very effective way of using biomass. For example, co-firing biomass in coal-fired power stations has a higher avoided emission per unit of biomass than when displacing diesel or gasoline with ethanol or biodiesel.
However, replacing natural gas for power generation by biomass, results in levels of CO2 mitigation similar to secondgeneration biofuels. Net avoided GHG emissions therefore depend on the reference system and the efficiency of the biomass production and utilisation chain.
In the future, using biomass for transport fuels will gradually become more attractive from a CO2 mitigation perspective because of the lower GHG emissions for producing second-generation biofuels and because electricity production on average is expected to become less carbon-intensive due to increased use of wind energy, PV and other solar-based power generation, carbon capture and storage technology, nuclear energy, and fuel shift from coal to natural gas.

In the shorter term, however, careful strategies and policies are needed to avoid brisk allocation of biomass resources away from efficient and effective utilisation in power and heat production or in other markets, e. How this is to be done optimally will differ from country to country.
The use of biomass for biomaterials will increase, both in wellestablished markets such as paper, construction and for possibly large new markets such as bio-chemicals and plastics as well as in the use of charcoal for steel making. This adds to the competition for biomass resources, in particular forest biomass, as well as land for producing woody biomass and other crops. However, increased use of bio-materials does not prohibit the production of biofuels and electricity and heat per se.
