Quicknote bioenergy economics In Europe and Canada, many vegetables and fruits are grown in greenhouses during the winter. Besides labor, energy is the biggest operational cost of running such a horticultural business. It does not come as a surprise then that, given record low temperatures and record high fuel prices, this industry is looking into alternative energy systems to heat its hot houses. This is a concrete example of how bioenergy can be both eco-friendly and economic.
In Québec, the Serres Jardins-Nature de Bonaventure, which produce 300 tons of organic tomatoes, have opted for biomass for several basic reasons. First of all the wood chips that are burned are eco-friendly and locally and abundantly available; secondly, prices are projected to remain very stable making heating costs lower overall than working either with natural gas, diesel or grid-electricity; thirdly, and most importantly, the mineral-rich ash that remains after the combustion of the woody biomass makes for an excellent organic fertilizer that will be used on the certified tomatoes.
Moreover, it can be argued that so-called 'organically grown' tomatoes are really not that environmentally friendly when they are cultivated in glass houses that utilize vast amounts of fossil fuel. After all, glass house horticulture is one of the most energy intensive agricultural sectors, emitting thousands of tons of CO2 into the atmosphere each year. A biomass heating system on the contrary is climate friendly. So in a sense, only vegetables that are grown in such a system deserve the 'eco' or 'bio' label. Organically grown, and not dependent on fossil fuels.
Contrary to its competitors, the greenhouse complex of Jardins-Nature de Bonaventure will be expanded from 8000 to 12000 square metres because it already foresees a competitive advantage over those who still heat with fossil fuels, but also because the project receives a small grant by the Québec government, which has launched a program to introduce renewable energy systems in the glass house horticultural industry. The Bonaventure tomatoes -- heated and fertilized by biomass -- will be sold in Québec, Ontario, and in the U.S.
Recently we focused on India's bioenergy strategies, and today an interesting development comes out of the same country: a bamboo-fuelled power station is being built in Mizoram state to help meet the energy needs of India's northeast. Bamboo is used on a daily basis by 2.5 billion people in the tropics and subtropics, mainly for food, feed and fiber. But the fast growing, tall grass, is looked at more and more as a fuel to generate green and renewable electricity. Mizoram produces 3.2 million tonnes of it per year, and is now going to use the local biomass resource to counter high energy prices.
Because of its high yields, its high energy content and its good combustion behavior, bamboo makes for an interesting energy crop. Compare it to woody biomass:
The physico-chemical characteristics of bamboo make it a solid biofuel similar to other woody fuels, with the exception of the mineral content which is higher for bamboo than for wood (2.5 % instead of 1.5 %), but much lower than coal.
Bamboo is also an interesting material for the production of charcoal. Its mass yield is higher (33 % on initial anhydrous mass) than that of wood wood (29 % on initial anhydrous mass).
The production of non-condensable gases is also higher (26.5 % vs 18-20 %), while tar production is lower (42 % vs 50 %).
Finally, bamboo's energy content (net calorific value) is comparable to or higher than other wood species like beech, spruce, eucalypts and poplars - in the range of 18.3-19.7 MJ/kg.
Mizoram's power station will be set up in Sairang village at an estimated cost of Rs 28,5 million (€500,000/US$615,000). "This cost-effective project has been conceived by the Indian Institute of Science, Bangalore, along with Ankur Scientific Energy Technologies, a private enterprise," said Benjamin L. Tlumtea, project coordinator of Zoram Energy Development Agency (ZEDA) [no website yet, but check here in the future].
"Raw material for the power project is easily available. Once the plan gets going we have plans to use the energy in some industrial units," Tlumtea said. Bamboo would be first harvested and then dried before it is processed for feedstock to produce gas, which would finally get converted to electricity. "With the help of such bamboo power projects and power generation through other non-conventional schemes, the state will surely solve its energy crisis," the official said. An estimated 9,000 sq km area is under bamboo cultivation in Mizoram. India, the world's largest producer of bamboo after China, grows about 80 million tonnes each year, more than half of it in the northeast.
Ever since Joseph J. Romm wrote The Hype About Hydrogen, more and more scientists have spoken out against the gas as a viable carrier for energy, and attention has radically shifted to biofuels. It looks like the 'hydrogen economy' has died, at least as a scientific concept. The main drawback with H2 is that it must first be produced, requiring a primary energy source, and this is where scientists see major obstacles: when fossil fuels are used, hydrogen is no longer a clean fuel and causes greenhouse gas emissions; when environmentally friendly wind electricity is used to generate the gas, only one-quarter of the energy generated by the wind turbine is eventually used to move a car. The rest is lost during transport and energy conversion; via solar power, the final yield is even lower.
There might however be a more efficient way to produce the gas, in such a way that the stages of the conversion process reinforce each other, instead of working against each other with energy losses as a result. We are talking about the production of hydrogen from biomass -- biohydrogen -- in a process that is being designed by several science institutions in a joint EU program called 'Hyvolution' that was launched at the beginning of this year.
Hyvolution fits in a futuristic vision of small-scale sustainable energy production from locally produced sources, in this case biomass. The end goal is to deliver prototypes of process modules which are needed to produce hydrogen of high quality in a bioprocess which is fed by multiple biomass feedstocks. As such, it is envisioned that small-scale modules can be used in a decentralized energy production structure, which makes them interesting for remote regions in the developing world (an ideal system for energy leapfrogging).
Bacteria do the work But how does the biohydrogen process work? In principle it comes down to producing pure hydrogen from biomass in a non-thermal process, through the combination of a thermophilic fermentation stage with a photoheterotrophic fermentation stage. In the first fermentation thermophilic bacteria are used to start the conversion of biomass which offers two important advantages. First, thermophilic fermentation at ≥70°C is superior in terms of hydrogen yield as compared to fermentations at ambient temperatures. In thermophilic fermentations, glucose is converted to, on average, 3 moles of hydrogen and 2 moles of acetate as the main by-product. In contrast, in fermentations at ambient temperatures, the average yield is only 1 to 2 moles of hydrogen per mole of glucose and butyrate, propionate, ethanol or butanol are the main by-products. The second advantage is the production of acetate as the main by-product in the first fermentation. Acetate is a prime substrate for photoheterotrophic bacteria. Through the combination of thermophilic fermentation with photoheterotrophic fermentation, a complete conversion of the substrate to hydrogen and CO2 can be established: biomass :: bioenergy :: biofuels :: sustainability :: bacteria :: fermentation :: hydrogen :: biohydrogen :: The Hyvolution program is structured around this core issue with a design aimed at closely associating the events in the chain from biomass to hydrogen. The process starts with the conversion of biomass to make a suitable feedstock for the bioprocess [see picture) (work package 1 / 'WP1'). The ensuing bioprocess is optimized in terms of yield and rate of hydrogen production through integrating fundamental and technological approaches, addressed in workpackage 2 and 3. Dedicated gas upgrading is developed for high efficiency at small-scale production units dealing with fluctuating gas streams (WP4). Production costs will be reduced by system integration combining mass and energy balances (WP5). The impact of small-scale hydrogen production plants is addressed in socio-economic analyses performed in work package 6.
Ten EU countries countries collaborate on the Hyvolution program, with Turkey and Russia joining as well with prominent specialists from academia and industries. Six small and medium sized enterprises are represented as well. The participants in Hyvolution have a complementary value in being biomass suppliers, end-users or stakeholders for developing specialist enterprises and stimulating new agro-industrial development.
Disadvantages remain However, many factors still plead against hydrogen as a viable energy carrier, even when derived from an efficient process using biomass as feedstock: after it has been produced, the gas is unstable and thus requires storage under high pressure which in itself costs energy. Biofuels are much more easy to handle and the hydrogen contained in them comes in a stable form. Speaking in terms of net efficiency, from a raw stream of biomass, roughly 40-50% can be thermochemically converted into a liquid fuel through steam reforming; the percentage is even higher for hydrogen, 50-60%, but after the compression phase, biofuels come out on top as the easiest and most efficient way to store hydrogen in a fuel ready to be used by consumers.
In short, why make the detour via hydrogen, when biomass can be turned into stable, easy to handle biofuels? Wim van Swaaij, professor of thermo-chemical conversion at Netherlands' Twente University, thinks that even the most efficient biohydrogen production process can never achieve the conversion efficiencies found in ordinary biofuel production.
Moreover, producing hydrogen, either through electrolysis using nuclear or renewable electricity, or refined from biomass or fossil fuels, requires massive amounts of water. One kilogram of hydrogen requires nine litres of water. The production of ordinary first generation biofuels is much less water intensive.
International research effort underway to sequence cassava genome, which may result in increased starch yields - USDA Agricultural Research Service - Aug. 30, 2006
Cassava has one of the highest rates of CO2 fixation and sucrose synthesis for any C3 plant. With this in mind, researchers from Ohio State University develop transgenic cassava with starch yields up 2.6 times higher than normal plants by increasing the sink strength for carbohydrate in the crop. This means cassava makes for a 'super crop' when it comes to both CO2 fixation and carbohydrate production, i.e. sugars, the feedstock for ethanol - Plant Biotechnology Journal - Volume 4/Issue 4 - July 2006
