As China turns its back on American ethanol in a lingering trade spat, Brazil is considering opening its doors to U.S. biofuel.

Brazilian authorities are debating whether to yield to Washington, D.C.’s request to lift ethanol-import duties as a way of facilitating talks for a bilateral trade deal with the U.S., two people with direct knowledge of the matter said. A broad trade accord would benefit many Brazilian products and may be announced by October.

Officials in Brazil’s Economy Ministry are willing to remove ethanol barriers while those from the more protectionist Agriculture Ministry are pushing to renew the current import quotas with zero tariffs, the people said, asking not to be identified because talks are private.

Two years ago, Brazil slapped a 20% tariff on U.S. ethanol shipments that exceed an annual quota of 600 million liters (158 million gallons) after American corn-ethanol imports surged, flooding the Brazilian market and pushing down prices.

A biofuel deal between the two nations would come as a relief for the U.S. ethanol industry, which has been beset by a supply glut and the weakest margins in more than 15 years. American producers had expanded rapidly to cater to fast-growing Chinese demand, only to be left without buyers amid President Donald Trump’s trade war with Beijing.

Indiana has the fifth-largest production capacity for fuel ethanol among states, according to 2018 numbers from the U.S. Energy Information Administration.

A decision would have to be made by the end of this month, when the quota expires and a 20% duty on all imports would go back into effect, the people said. Brazil’s sugar-cane industry group Unica and the Economy and Agriculture ministries didn’t immediately respond to requests for comment.

The administration of President Jair Bolsonaro would at least exclude some American ethanol shipments from the 20% tax in order to preserve relations given Brazil is striving to address other U.S. trade complaints, according to the people. In March, Brazil agreed to open a wheat import quota of 750,000 tons a year free of duty, a move U.S. Wheat Associates says could benefit American farmers.

In a worst-case scenario, the Economy Ministry would extend the 600 million-liter quota to gain more time to negotiate, the people said.

Brazil was the top destination for U.S. corn-ethanol shipments last year, with imports of more than 1.7 billion liters.

Many ethanol plants are up to 15 years old, or older, and the subject of increasing production, efficiency and profitability is more prevalent than ever. With new, more efficient technologies coming to market for various processes within a biorefinery, the desire to debottleneck older equipment can drive maintenance and capital project decisions.

Producers must decide if they want to budget and plan to maintain, upgrade or scrap and replace with a new unit. When it comes to boilers and heat recovery steam generators (HRSGs), maintenance cost and upgrade opportunities often dictate the conversation.

Tools for Making Data-Driven Decisions
Fully assessing the operation of a boiler or HRSG requires accounting for multiple factors including how a process change will affect related equipment, not just the direct system involved. Process operators and plant engineers can utilize the distributed control system (DCS) to perform on-the-fly performance checks confidently. Combining this with information located in the original equipment manufacturer (OEM) predicted performance data sheets, producers can estimate as-is performance while operating. Additionally, the data historian system provides the ability to trend data over time, providing long-term review capabilities of the boiler.

Where Modeling and Data are Key
While a control room data assessment can give a brief insight of as-is performance, it doesn’t tell the whole story. Boilers are often run differently than originally designed, making a direct comparison to the OEM predicted performance difficult. Additionally, a process change—such as dryer throughput or feedwater temperature—can greatly affect multiple aspects of the system that are not as easily quantified.

A thermal model can provide more accurate insight into the boiler performance and help fully assess the system. Modeling provides a digital representation of the boiler system, taking into consideration the physical geometries of the water and gas-side flow paths, along with OEM predicted performance values used to validate the model.

Taking it one step further, DCS and process information (PI) historian data can be reviewed and matched to the thermal model to provide an as-is representation of operation, ideal for plants that have been operating for multiple years or have changed components. Accurate data is important, so performing mass and energy balances about various sections of the boiler is needed to identify good and bad data, which leads to investigating and correcting miscalibrated instruments or DCS conversion algorithms.

Once developed, the model can be used to track degradation, identify under or overperforming sections of the boiler and simulate upgrade and process changes, as well as provide key insights into pressures, temperatures, flows and how they affect ancillary equipment.

Case Study: Process Upgrade Effects
A facility comprised of two identical firetube waste heat boilers, operating in parallel and sharing a common final steam separator, was investigated for a potential upstream process upgrade being performed elsewhere in the plant. Using HRST’s PerformancePro thermal modeling software, a thermal model was developed based on the OEM thermal and mechanical data sheets. Typical process conditions gathered from the PI data historian were used to replicate the existing boiler operation, creating an as-is representation of the system performance.

The process upgrade parameters were provided by the plant, including values for increased boiler feedwater (BFW) temperature, as well as flue gas temperatures and mass flow rates. Primary areas of concern were the American Society of Mechanical Engineers boiler design pressures and temperatures, stamped boiler capacity, safety relief valve pressure set points and relieving capacity, as well as the final steam separator capacity.

Upon modeling and subsequent analysis, it was determined that multiple shortfalls existed in the system when simulated under the process upgrade conditions, including:

• Metal temperatures exceeding the ASME design temperatures for the upstream tube sheet, tube inlets and, in some cases, the bulk tube temperature.

• Steam generation exceeding the boiler rated capacity and the safety valve relieving capacity.

• Combined (boiler one and two) steam flow exceeding the final steam separator capacity.

Additionally, it was determined that the pressure drop from the boiler to the main steam header would increase on the order of 2.25 times over existing, and the increased flue gas mass flow and temperature would increase the stack temperatures by 40 to 70 degrees Fahrenheit over the current baseline.

Solutions for meeting ASME code would require a capacity and design temperature rerate, whereas the final steam separator would only require upgraded internal equipment to meet capacity requirements. To rerate for higher temperatures, a condition assessment of all tubes and welds would be required to validate the component thickness for ASME code calculations. Plant personnel said abrasive particulates in the flow eroded tube inlets, causing plugging.

While a steam capacity rerate would be advantageous, discussion with plant personnel determined that the scope required to validate all tube and pressure part thicknesses would be costly and, because of the failure history, may only indicate that a temperature rerate would not be possible.

Because of those factors and the age of the boilers, the plant opted to continue use under existing conditions for the short term. Ultimately, the decision was made to replace each of the boilers with newer, higher-capacity units specifically designed for the upgrade parameters, with results of the thermal modeling assessment used as justification.?

Key Takeaways
When it comes to making long-term decisions about boiler operation or replacement, historical operating data trends and future operating conditions can provide helpful insight and, when combined with system modeling, create a useful tool to analyze the boiler as well as ancillary equipment.

Approaches such as this can help operators and plant management make data-driven decisions when facing the choices to maintain, upgrade or replace.

The New York Department of Agriculture and Markets published a proposed rule July 24 to allow E15 sales within the state. The move will soon open the nation’s fourth largest gasoline market to sales of the fuel blend.

The rulemaking comes nearly a nine years after the U.S. EPA first issued a waiver allowing E15 to be used as fuel in certain vehicles and less than two months after the agency took action to allow E15 to be sold year-round. E15 can currently be used to fuel model year 2001 and newer vehicles.

The rulemaking marks the second effort New York has made to allow sales of E15. A proposed rule issued by the New York Department of Agriculture and Markets in August 2016 was withdrawn the following month. In a notice posted to the New York State Register Sept. 21, 2016, the department said the proposed rule was withdrawn because “several objections were received to the express terms of the proposed rule.”

The new proposed rule published by the New York Department of Agriculture and Markets aims to update the state’s fuel regulations to allow the sale of E15. A 60-day public comment period on the proposal opened July 24.

Chris Bliley, vice president of regulatory affairs at Growth Energy, has expressed confidence that the rulemaking could be finalized by the end of the year.

According to Bliley, Growth Energy has been engaged in the process to open the New York market to E15 for the past five years, working with government agencies, local consultants and New York-based ethanol producer Western New York Energy.

“We’ve had lots of good discussions with the New York Department of Agriculture and Markets,” Bliley said, noting the department held stakeholder meetings earlier this year that Growth Energy participated in. The trade group has also had discussions with other state agencies that had questions and wanted to better understand ethanol and E15, he said.

“It’s been a really long effort, but we are certainly pleased to see [the state] move forward with the proposed rulemaking, and now look forward to its adoption,” Bliley continued.

Bliley said the proposed rulemaking sends a strong signal to New York fuel retailers that they will soon be able to sell E15. The state represents the nation’s fourth largest gasoline market, with annual consumption of approximately 5.7 billion gallons of gasoline, he said. For E10, that volume of gasoline consumption translates into approximately 570 million gallons of ethanol demand. Bliley said that if the whole state moved to E15, that would represent demand for about another 285 million gallons of ethanol, roughly equivalent to 100 million bushels of additional corn.

While other states in the Northeast don’t have the same outright restrictions on E15 that New York does, New York’s action to allow E15 sales could help increase demand for the fuel within the region. “What we’ve certain in other states and locations is that once you have one or two marketers installing the fuel, it certainly puts competitive pressure on others in the area to start offering it as well,” Bliley said.

Moving forward, Bliley said Growth Energy will be filing comments in support of the proposed rule. “I know others will be weighing in with strong support as well,” he said, stressing that New York’s action to allow the fuel is exciting for Growth Energy.

A full copy of the proposed rule is available on New York State Register website.

Minnesota Bio-Fuels Association vendor member, Pinnacle Engineering, Inc., recently celebrated its 28th anniversary.

The Minnesota Bio-Fuels Association’s (MN Biofuels) 2019 First-Half Report was released to its members July 17, and the report highlights the organization’s push to grow the use of E15 in Minnesota, and the impacts the one-pound RVP waiver for the fuel has had on the state.

In a release, Tim Rudnicki, executive director of MN Biofuels said, “This year, as of May 31, E15 sales in Minnesota have hit 29.26 million gallons and with E15 now available throughout the summer, we have launched several promotional campaigns aimed at further increasing E15 consumption this year. Moreover, with E15 now available year-round, there will be new opportunities to increase the number of fuel retailers who offer E15 in Minnesota.” According to the report E15 is currently offered at 352 retail locations in Minnesota. Rudnicki added that Minnesota needs 660 stations offering the blend to make it drivers’ go-to fuel.

“With the RVP ban lifted, E15 can finally take off,” Rudnicki said. “But for that to happen, we have to continue to educate and engage with consumers on the benefits of using E15 and get more retailers onboard.”

And more retailers have started to jump onboard, Rudnicki said. “Since the ban was lifted, interest in E15 among independent retailers, especially those with multiple stations, have certainly increased. It was previously very difficult to convince some stations to take on a product they could only sell for 8.5 months a year,” he said.

In addition to focusing on E15 growth, the report highlights other initiatives undertaken during the first six months of the year. In terms of policy and advocacy, MN Biofuels worked with members of the state legislature and the governor’s office to expand the biofuel infrastructure partnership program. “While we made great strides in creating awareness about the need to increase the availability of E15 in Minnesota, funding for the initiative was constrained by lawmakers’ budget targets,” the report says. “Nonetheless, we will continue to work with agency heads and the governor to identify discretionary funds for this initiative.”

Rudnicki said MN Biofuels has data and evidence “that indicates a second BIP program could be one of the most cost-effective methods to boost E15 on the supply side. At the same time, organizations like MN Biofuels will continue to educate and promote E15 to consumers to boost demand. That's good for the farmer, economy, consumer and the environment,” Rudnicki said.

Looking ahead, the report says MN Biofuels plans to research proposals for a low carbon fuel standard. “Some environmental and biofuel stakeholders have already attempted to draft a model standard; however, a preliminary assessment indicates a host of questions about its effectiveness and implications for the ethanol industry in Minnesota have yet to be addressed,” the report says.

“There are a number of questions we have about proposed models and whether they actually recognize the evolving reality such as the growing number of hybrid vehicles and the role of mid-level blends of ethanol in helping to boost engine performance and cut greenhouse gas emissions in the transportation sector,” Rudnicki added.

Senator Chuck Grassley

July 23 2019

Press Release

Contrary to assertions by the EPA, the Energy Department confirmed in a letter to Senator Chuck Grassley (R-Iowa) that the EPA has issued so-called “economic hardship” exemptions under the Renewable Fuel Standard (RFS) to small refineries, often owned by billion-dollar oil companies, even when the Energy Department found that the refineries faced little or no actual “hardship.”

In a response to an April 10 letter from Grassley, Secretary of Energy Rick Perry outlined the role of the Energy Department in the issuance of these waivers and indicated EPA has on at least one occasion issued an exemption when the department recommended no exemption and has ignored recommendations to grant only partial exemptions in other cases. Perry also indicated that the department has not changed how these analyses are applied or scored from the prior administration. Full text of Perry’s letter to Grassley is available HERE.

The number of small refinery waivers issued by EPA has skyrocketed the last two years.

In his April letter, Grassley specifically sought clarity on whether the Energy Department had changed its criteria or methodology of how it makes recommendations to EPA for small refinery exemptions. He also requested information about how many instances EPA granted the exemptions without recommendation from the department.

“This confirms what we’ve suspected and has been reported by news media,” Grassley said. “President Trump delivered on E15, but EPA has been undermining the president’s commitment to Iowa, the Midwest and rural America. I hope the White House puts an end to these handouts to Big Oil that hurt American farmers.”

Grassley is a leader in the fight to maintain a strong Renewable Fuel Standard (RFS). He led efforts to put pressure on the EPA to stop issuing “hardship waivers” to large, highly profitable oil companies as well as make the waiver process more transparent and highlight the importance of the RFS to President Trump and his administration.

A recently released report from the USDA Foreign Agricultural Services Global Agricultural Information Network says South Korea may soon revise its regulations to allow the use of ethanol-blended fuel. The report follows the 2019 Seoul Fuel Ethanol Conference, hosted by the U.S. Embassy Seoul’s Office of Agricultural Affairs, the U.S. Grains Council and the Korea Biofuels Forum.

“Despite acknowledged air quality issues in urban centers, Korea does not currently allow the use of ethanol as a transportation fuel,” the report says. “With growing public concern about air quality issue in the transportation sector, the growing use of ethanol in transportation fuel in neighboring countries, and Korea’s interest in diversifying energy sources, FAS Seoul is optimistic that Korea will soon move towards approval for some ethanol use in fuel.”

According to the report, the South Korean government recently studied the feasibility of using ethanol-blended fuels in its transport sector. The feasibility study is currently under review by the ministry of Trade, Industry and Energy “which will finalize a recommendation on whether to permit ethanol fuel blends in the near future,” the report says.

The conference, which was held at the end of April, included presentations from representatives of the U.S. Grains Council and Flint Hills Resources, as well as a panel discussion titled “The Necessity of Korea’s Fuel Ethanol Policy and Future Roadmap.” The 2019 conference was the largest since its inception four years ago.

Following the conference, a release from the U.S. Grains Council noted that South Korea imported over 56 million gallons of U.S. ethanol between September 2018 and February 2019. That ethanol is used only in the country’s beverage and industrial sectors; however, the Grains Council is also hopeful the transport sector will provide further export opportunities for U.S. ethanol.

Renewable Fuels Association

Two new academic studies released this week provide further evidence that grain-based ethanol is significantly reducing greenhouse gas emissions and call into question the reliability of recent “land use change” analyses based on flawed satellite imagery-based methodologies.

These studies add to a large body of existing literature that debunks falsities spread by well-funded opponents about the role ethanol plays in protecting the environment.

According to the Renewable Fuels Association, this new research will allow policymakers and regulators to focus on the fact that corn farmers and ethanol producers alike are making great strides forward in sustainability and efficiency.

“As the Environmental Protection Agency considers the GHG impacts of expanded ethanol consumption under the Renewable Fuel Standard, we urge them to strongly consider the latest science and data regarding ethanol’s tremendous carbon benefits,” said RFA President and CEO Geoff Cooper. “At the same time, we implore EPA to exercise great caution and prudence when considering the results of flawed land use change studies reliant on data from satellites that, frankly, can’t tell the difference between a pasture and a parking lot. The land use research relied upon by EPA for its Second Triennial Report to Congress was so flawed and erroneous that it simply cannot be used for regulatory decision-making, and we urge EPA not to make the same mistake as it considers future regulatory actions on the RFS.”

The first new study, conducted by the Laboratory for Applied Spatial Analysis at Southern Illinois University Edwardsville (SIUE-LASA), exposes fundamental flaws in satellite imagery-based research regarding land use change that was quoted in the EPA’s Second Triennial Report, released in 2018. SIUE-LASA’s review of the data sets and methodologies that were used in the prior research revealed some remarkable errors.

A series of papers by Tyler Lark, Holly Gibbs and Christopher Wright relied heavily on use of the U.S. Department of Agriculture’s Cropland Data Layer (CDL), which assigns land type categories using satellite imagery. Their research suggests there has been conversion of grassland and other “native” lands to cropland since the Renewable Fuel Standard was established. However, the CDL has shortcomings that render it poorly suited for this type of analysis, notably the inability to differentiate between grassland types (native prairie, Conservation Reserve Program, grass hay, grass pasture and fallow/idle grasslands), a problem USDA itself has recognized.

In one egregious example where the CDL failed, a body of water was misclassified as deciduous forest and grass pasture. Click here for the image example. This example is symptomatic of the errors associated with the CDL, underscoring why the research based on this data should not be used for regulatory decision-making.

Additionally, the research by Lark, Gibbs, and Wright (much of which was funded by the National Wildlife Federation) is prone to reflecting “false change,” in which a higher share of actual cropland is recognized in the newer, more-accurate CDL versions than in older, less-accurate versions, thus giving the appearance that cropland expanded.

For example, SIUE-LASA examined conditions in Iowa, since it is a leading producer of corn and ethanol and previous research asserted Iowa was an area with significant land use change. Using data from the USDA’s National Agricultural Statistics Service, SIUE showed that from 2008 to 2012 in Iowa there was a net increase of only 38,000 acres of cropland as opposed to 263,468 acres and 295,100 acres claimed in two satellite data-driven papers cited by the EPA in its 2018 report.

The land use research (“Critical Review of Supporting Literature on Land Use Change in the EPA’s Second Triennial Report to Congress”) was conducted for Renewable Fuels Association by Joshua Pritsolas and Dr. Randall Pearson of SIUE-LASA. In summary, the authors found “…there are major concerns regarding both the data and the methods that were used by the researchers [Lark, Gibbs, Wright], which call their findings into question.”

Click here for the full report.

The second new study, a worldwide meta-analysis funded in part by the Department of Energy and  USDA, determined that corn residue (“stover”) retained on fields—which is the common practice—results in the sequestration of approximately 0.41 metric ton of carbon per hectare per year  in the soil.  This implies not only that the carbon intensity of corn-based ethanol is significantly below current estimates by EPA, the California Air Resources Board, and others, but also that leaving more residue on the field can have a larger carbon benefit than significant removal and conversion of the residue into ethanol.

Based on this research, properly accounting for the soil carbon sequestration benefits of corn production would reduce the existing lifecycle “carbon intensity score” of corn ethanol by some 20-25 percent, meaning most dry mill corn ethanol produced today would result in a 50-65 percent GHG savings compared to gasoline.

The soil carbon sequestration research was conducted by a team of environmental and soil scientists from the Department of Energy’s Argonne National Laboratory, the U.S. Department of Agriculture’s Agricultural Research Service, South Dakota State University and the South Dakota School of Mines and Technology. They used 409 data points from 74 stover harvest experiments conducted around the world. The paper, titled “A global meta-analysis of soil organic carbon response to corn stover removal,” was recently published in GCB Bioenergy, an international journal. Click here to read it.

The International Renewable Energy Association recently released the sixth edition of it Renewable Energy and Jobs report, announcing the renewable energy sector employed at least 11 million people last year, directly and indirectly. The solar photovoltaics, bioenergy, hydro, and wind power industries were the biggest employers.

Bioenergy, which includes liquid biofuels, solid biomass and biogas, employed approximately 3.18 million people last year, up from 3.06 million in 2017 and 2.74 million in 2016.

Approximately 2.063 million people were employed by the liquid biofuels industry in 2018, with 787,000 employed in solid biomass and 334,000 employed in biogas.

According to IRENA, worldwide biofuels employment is estimated at 2 million, up 6 percent from 2017. Many of the jobs in the sector are generated in planting and harvesting of feedstock. Fuel-processing facilities tend to offer fewer jobs than feedstock supply. However, those jobs typically required higher technical skills and offer better pay.

With 832,000 jobs, Brazil has the world’s largest workforce in liquid biofuels. In the U.S., record production in 2018 drove up liquid biofuels employment to 311,000 jobs. Biofuel employment in the EU reached approximately 208,000 jobs in 2017, which is the most recent year for which data is available. Brazil, the U.S. Indonesia, Columbia and Thailand are the top five countries for employment in liquid biofuels.

Heat and electricity derived from solid biomass accounted for approximately 387,000 jobs in the EU in 2017.  There were approximately 186,000 jobs attributed to solid biomass in China, with 79,000 in the U.S. and 58,000 in India.

For biogas, approximately 145,000 of the estimated 334,000 jobs were in China, with 85,000 in India, 67,000 in the EU and 7,000 in the U.S.

US airline Delta has flown its first carbon-neutral delivery flight, using biofuels and carbon offsets, as the airline continues towards its goal of a 50% carbon emission reduction by 2050.

Delta has teamed up with biofuel supplier Air BP for the provision of biofuels for an initial 20 delivery flights from the Airbus final assembly line in Mobile, Alabama, US.

The Airbus aircraft are manufactured and refined using sustainable sources and processes, the airline added.

“Today’s carbon-neutral delivery flight is a milestone on Delta’s sustainability journey as we work to cut carbon emissions in half by 2050,” said Alison Lathrop, Delta’s managing director – global environment, sustainability and compliance. “We are excited to partner with Air BP and Airbus to power these delivery flights with biofuels and carbon offsets, and will explore opportunities to bring this level of sustainability to all delivery flights going forward.”

Delta has reduced its consumption of traditional jet fuel since 2005, resulting in an 11% decrease in emissions.

The airline was the first and only US airline to voluntarily cap carbon emissions at 2012 levels by purchasing carbon offsets ahead of the International Civil Aviation Organisation’s CORSIA implementation, which caps international emissions from aviation at 2019/2020 levels.

“Airbus is committed to being part of the solution for meeting aviation’s global CO2 emissions reduction targets,” added Simone Rauer, head of aircraft operations for environmental affairs at Airbus. “Contributing to a lasting decrease of our industry’s carbon footprint is key to ensuring a sustainable future for aviation.”

“We are proud to help Delta achieve its sustainability goals for the maiden voyages of their new Airbus aircraft,” said Jon Platt, CEO of Air BP. “Air BP is supplying sustainable aviation fuel, produced by Neste, for 20 delivery flights, and through the BP Target Neutral program we are offsetting the residual carbon emissions of each delivery flight. This is another example of BP’s commitment to advancing the energy transition and helping our customers meet their lower carbon goals. We hope this project inspires others to follow suit.”
