Cooking Better Biochar: Study Improves Recipe for Soil Additive

ScienceDaily (Mar. 22, 2012) — Backyard gardeners who make their own charcoal soil additives, or biochar, should take care to heat their charcoal to at least 450 degrees Celsius to ensure that water and nutrients get to their plants, according to a new study by Rice University scientists.

The study, published this week in the Journal of Biomass and Bioenergy, is timely because biochar is attracting thousands of amateur and professional gardeners, and some companies are also scaling up industrial biochar production.

“When it’s done right, adding biochar to soil can improve hydrology and make more nutrients available to plants,” said Rice biogeochemist Caroline Masiello, the lead researcher on the new study.

The practice of adding biochar to topsoil to boost crop growth goes back centuries, but in recent years, international interest groups have begun touting biochar’s climate benefits as well. Biochar removes carbon from the atmosphere and locks it into the soil for hundreds and sometimes thousands of years.

Advanced Biofuels Industry Hunkers Down for Hard Times

Facing an uncertain future with biofuels policy under scrutiny, the advanced biofuels industry convened for a three day conference in San Francisco earlier this month. Jointly organized by Green Power Conferences and Biofuels Digest, the Advanced Biofuels Markets conference is one of the few industry events bringing together industry leaders from all shades of advanced biofuel interests – algae, cellulosic biofuels, advanced biodiesel, aviation biofuels, and others – as well as key public-sector stakeholders.

Coming off several years of steady industry growth but facing a difficult 2012, Advanced Biofuels Markets 2011 was tinged with exigency. With deficit reduction at the forefront of policy objectives for Congress, a reexamination of cornerstone policies supporting biofuels growth is expected. At risk of being scrapped altogether, the checkerboard foundation of biofuels policy initiatives spanning EPA, USDA, the Department of Energy (DOE), the Department of Defense, Treasury and others – including RFS2, Title IX programs under the Farm Bill, DOE loan guarantees, VEETC, etc. – may be placed on the chopping block one by one (or in the most dramatic scenario, slashed all at once).

What does this mean for an industry on the cusp of commercialization, but still a few nickels to several dollars shy of price parity with a gallon of petroleum fuel? For the most part, it adds a great deal of uncertainty, making an already difficult financing story even more risky for would-be investors. In the more extreme case, the sentiment among conference panelists was that the industry is now fighting for its future existence in the U.S.

The Lost Years

With an unresolved deficit crisis casting an ominous shadow over 2012, the coming year is shaping up to be challenging for advanced biofuel companies still navigating the funding “valley of death” and facing a particularly daunting scale-up challenge. Just as many advanced ethanol projects are beginning to break ground, a number of incentive and loan programs are likely to be nixed. Energy provisions in the 2012 Farm Bill are of primary concern. Programs, including USDA loan guarantees for biorefinery projects, Biomass Crop Assistance Program (BCAP), and Rural Energy for America Program (REAP), are all critical lifelines for an industry still looking to establish a foothold.

Addressing the so far undelivered promise of cellulosic biofuels – biofuels derived from the lignocellulose portion of plant matter – Alan Shaw, CEO of Codexis, explained that the technology is “late to its own party.” After lobbying for nearly a decade for R&D funding, inclusion in biofuels mandates, and subsidy parity with conventional biofuels, the cellulosic biofuels industry has received a great deal of support over the last couple of years. While not necessarily on equal footing with conventional (corn-based) ethanol, cellulosic biofuels were given a commercialization runway to 16 billion gallon by 2022 under the EPA’s RFS2 mandate. But only a few million gallons of cellulosic biofuels have been produced and the first facilities are still under construction, forcing policymakers to question the viability of the technology in the near-term.

The failure of cellulosic biofuels to capitalize on its opportunity thus far has led to increased attention to technologies such as pyrolysis and thermo-catalytic or advanced sugar fermentation. As a result, cellulosic biofuels – once the priority advanced conversion pathway for the DOE – are now finding it difficult to raise capital to support widespread scale-up. Many panelists at the conference concurred that it’s time to deliver or risk losing priority status among advanced biofuel conversion pathways.

In our Biofuels Markets and Technologies report, we forecast growth rates in the U.S. biofuels industry to lag behind other regions.

“Don’t Mess with the RFS”

Of particular concern among industry stakeholders at the conference is the battle to hold the line on the EPA’s RFS2 biofuels mandate, which aims to boost biofuel production in the United States through 2022. Although RFS2 has proved to be a complex rule to implement, it is one of the few mandates worldwide that carves out specific volume requirements for various biofuel conversion pathways.

While some in the advanced biofuels industry are calling for opening up the mandate to more advanced pathways (such as algae-based biofuels, waste-derived fuels, etc.), most warn that doing so would mean opening up the standard entirely, which could jeopardize its continued existence. In any case, within the broader battle for favorable treatment of advanced biofuels in Washington, RFS2 is seen as the last line of defense for an industry still struggling to gain a foothold.

Key Takeaways

To turn the corner on advanced biofuels commercialization, conference panelists urged producers to remain flexible with respect to feedstock and end-product. With policy up in the air, the ability to shift production to advanced chemicals, aviation biofuels, and ground transportation fuel depending on market forces and prevailing policy sentiment will make projects a far more attractive bet for skittish investors. Partnering, especially with oil majors, multinational chemical and consumer product companies, and other end-market players, is increasingly seen as the way forward in a challenging financing environment.

Biomass 2012: International Growth and Domestic Obstacles

In 2012, expect to see the continued development of the biomass industry in the European Union and other areas of the world. Currently, the U.S. leads the world in biomass power capacity, but that is beginning to change. The North American wood pellet industry has become a major supplier to the EU. The volume of EU-bound wood pellet shipments in 2010 was double that of 2008, with the Netherlands, the U.K. and Belgium leading the demand. From 2008 to 2009 the EU’s gross electricity production from biomass increased more than 10 percent, with Germany, Sweden and the U.K. leading the way. The U.K., in particular, is focusing its efforts on developing its biomass capacity. October saw the U.K. propose subsidies to business customers (to be followed by households after the program was established) who use renewable energy technology for heating. While the program’s rich subsidy was scaled back (from 2.7 pence per kilowatt hour (kWh) to 1 pence per kWh), the efforts show clearly that the political will is in place to continue to support the biomass industry. The U.K.’s proposals included as a key goal the development of “cheaper” renewable generation, focusing specifically on the conversion of coal plants to biomass and cofiring plants.

But the U.K. is not the only place to see recent movement in the biomass space that is expected to continue throughout 2012. India, Japan and Brazil have also added biomass power capacity with additional projects in development phases. In addition, biogas is expected to see significant growth in Italy, France and Spain. China, in particular, has set ambitious goals for its biomass industry. By 2015, China wants to have 13 gigawatts of biomass power capacity, which is a 160 percent increase from its 2010 capacity. This means China anticipates adding 500 to 700 biomass power plants by 2015. With a biomass reserve equivalent to 500 million tons of coal, from sources such as straw, algae, methane, fallen timber and manure, China may very well emerge as the new high-growth country in the biomass space.

The U.S. biomass industry is growing, though it will continue to face significant challenges during 2012. But first, some success stories. Several new biomass plants are under construction (not just in the development stage) including 100 megawatt (MW) plants in Texas and Florida and smaller 50 to 75 MW plants in New Hampshire and Florida. Several more plants are in the development phase, with construction expected to begin in 2012. Most of these plants are located in rural areas where jobs are needed the most. New plant construction and job creation will go a long way to garnering the political support needed to move the industry forward.

What the biomass industry can’t control is the price of natural gas and oil. Further, the inability to establish an acceptable definition of “biomass” has torn the industry’s focus away from developing its supply chain and establishing its presence as a cost-effective alternative to fossil fuels. In addition, we are seeing a shift toward investment in smart grid and energy efficiency technologies, which may result in a focus away from biomass projects, at least in the short term. Energy service providers are focusing more on smart grid technologies, as a result of commercial customer demand for real-time energy management capabilities, through the acquisition of battery storage and consumer-driven energy management technologies.

In 2012, the biomass industry needs to focus on the positive economic benefits it brings to communities and the importance of energy independence. Further, while establishing a biomass definition is important, let’s not allow that debate to divert precious time and energy away from the development of a cost-effective supply chain and establishment of biomass as an alternative energy source to fossil fuels.

Wood Biofuel Could Be a Competitive Industry by 2020

ScienceDaily (Nov. 8, 2011) — Fuel made from wood could become a competitive commercial alternative to fuel made from corn by 2020 if the wood biofuel industry is supported, according to a new University of British Columbia study.

Corn ethanol is currently blended with gasoline to satisfy government-mandated targets to include renewable content in transportation fuel. Compared to corn, wood-based biofuel is considered more sustainable but is not currently produced in large commercial quantities in Canada and the United States because the costs are too great.

The study, published in the most recent issue of the journal Biofuels Bioproducts & Biorefining, identifies several opportunities for reducing these costs. Researchers in UBC’s Faculty of Forestry found that large-scale commercial production of wood-based ethanol, also known as cellulosic ethanol, will reduce capital and operation costs and assist in achieving the improvements necessary for wood-based ethanol to compete, without government support.

Using Biochar to Boost Soil Moisture

By Ann Perry

Scientists at the U.S. Department of Agriculture (USDA) are leading the way in learning more about “biochar,” the charred biomass created from wood, other plant material, and manure.

The studies by Agricultural Research Service (ARS) scientists at laboratories across the country support the USDA priorities of promoting international food security and responding to global climate change. ARS is USDA’s chief intramural scientific research agency.

Soil scientist Jeff Novak at the ARS Coastal Plains Soil, Water and Plant Research Center in Florence, S.C., is coordinating the multi-location effort. In one project, he led a laboratory study to see if different biochars could improve the sandy soils found on the Carolina coastal plain, and Pacific Northwest silt loam soils derived from volcanic ash.

Novak’s team used peanut hulls, pecan shells, poultry litter, switchgrass and hardwood waste products to produce nine different types of biochars. All the feedstocks were pyrolysed at two different temperatures to produce the biochars. Pyrolysis is a process of chemical decomposition that results from rapid heating of the raw feedstocks in the absence of oxygen. Then the biochars were mixed into one type of sandy soil and two silt loam soils at the rate of about 20 tons per acre.

After four months, the team found that biochars produced from switchgrass and hardwoods increased soil moisture storage in all three soils. They saw the greatest increase in soils amended with switchgrass biochar produced via high-temperature pyrolysis—almost 3 to 6 percent higher than a control soil sample.

Biochars produced at higher temperatures also increased soil pH levels, and biochar made from poultry litter greatly increased soil levels of available phosphorus and sodium. The scientists also calculated that the switchgrass biochar amendments could extend the window of soil water availability by 1.0 to 3.6 days for a soybean crop in Florence, and could increase soil water availability for crops grown in Pacific Northwest silt loam soils by 0.4 to 2.5 days.

Given their results, the team believes that agricultural producers could someday select feedstocks and pyrolysis processes to make “designer” biochars with characteristics that target specific deficiencies in soil types.

Results from this study were published in Annals of Environmental Science and in the Journal of Environmental Quality.

In August, we marked the 100th anniversary of a fiery phenomenon known as the Big Burn.

Over two late summer days in 1910, in western Montana and northern Idaho, more than

3 million acres of forest and several towns went up in smoke. More than 2,700 lightning-caused forest fires resulted in 85 deaths.

Today’s conditions are prime for a repeat. The culprits? There are several contributing factors, but the primary cause is climate change. For 304 consecutive months, the average world temperature has been higher than the established monthly average. For the past four months, that number has been a record high. Add in a long drought cycle in the West, and the threat of devastating fire, as recently seen in Colorado and California, looms large.

Changes to the landscape have occurred, with Nevada’s population growth and other more intensive land-management activities. Our recent fire-suppression efforts have had unintended negative consequences. With fewer fires, the pinyon and juniper woodlands grew at unprecedented rates, literally “giant stepping” from their traditional ranges onto nearby sagebrush and grass lands.

A new program at the University of Nevada, Reno is leading to solutions that will help mitigate the threat of a repeat of the Big Burn.

Increased rangeland and watershed restoration projects are underway throughout the state. The Wood Utilization Program, part of the College of Business’ Business Environmental Program, is providing wood-based industries with utilization and marketing assistance. Working in concert with BLM, USFS and USDA personnel, the university is developing economic strategies and introducing technologies that will improve the value of forest and rangeland materials.

The problem is, Nevada’s pinyon and juniper don’t have significant commercial value. They don’t have a lumber value that attracts traditional sawmill entrepreneurs. The species, known to local foresters as “PJ,” are relegated to biomass status. Firewood, fuel chips, mulch and compost are the typical “end-of- life-cycle” products for PJ. However, their status could be changing.Research at the University and DRI points to higher-end uses for PJ. Converting the biomass to cellulosic ethanol, torrefied fuel stock for co-firing at coal power plants, or creating biochar as a soil amendment and carbon sequestration agent all are possibilities that could improve the economics of thinning, increasing the number of acres that can be treated, as well as increasing the pace of watershed restoration.
