Feedstock growers typically look at how many trees they can plant per acre rather than the quality and volume of fuel those trees will produce. To address the issue, the researchers analyzed 900 samples of black cottonwood trees -- a type of fast-growing poplar -- grown in Oregon to determine how variations in their size and composition affect feedstock quality and biorefinery economics.
The researh found the amount of fuel produced per-acre per-year and the minimum fuel selling price(MFSP) are most strongly connected to the size of a tree. Since a farmer would only plant the biggest and fastest growing trees, the researchers examined those and found that the size and sugar content in those trees were of nearly identical importance to the MFSP.

The single step CADO process is capable of converting vapor of wet ethanol into hydrocarbon blendstocks competitively priced at $2/gigajoule that can be blended with gasoline, diesel, or jet fuels to diminish emissions of greenhouse gases.
The conversion procedure of fuel uses zeolite, a kind of catalyst, to create actual loner chains of hydrocarbons from ethanol (alcohol). The process substitutes the traditional multi-step processes and uses less energy.

"The US has not come here in good faith. They continue to block the world's efforts to help people whose lives have been turned upside down by climate change."
"Developing countries came to this climate conference with the expectation that the people who have lost their crops to drought, or who have lost their homes to cyclones, will finally get help from the UN system. Instead, they have faced bullying, arm-twisting and blackmail. Rich countries most responsible for the crisis have refused to provide a single penny of new money to support communities to recover from the devastation caused by increasingly frequent and severe climate disasters." -- Harjeet Singh, ActionAid Climate Lead
"Major players who needed to deliver in Madrid did not live up to expectations. But thanks to a progressive alliance of small island states, European, African and Latin American countries, we obtained the best possible outcome, against the will of big polluters." -- Laurence Tubiana, European Climate Foundation, CEO, France's Top Climate Negotiator and Architect of the Paris Agreement.
"The only thing more disastrous than the state of UN climate negotiations at COP 25 is the state of the global climate. This is nothing less than a breakdown in the Paris Agreement. This is not climate leadership, this is a betrayal of humanity and future generations," -- Eric Holthaus, Meteorologist
"What's happening today at COP 25 is a clear and present threat to civilization itself. The Trump administration and its fossil fuel allies around the world have sabotaged the Paris Agreement -- the only global treaty we have to fight climate change. This is a betrayal of humanity.
"For so many people gripped by devastating floods, fires, and storms, time is up. And instead of helping them, rich countries hold on to your dollars and hold up loss and damage. Public mobilizations are swamping the streets. The status quo you are working so stubbornly to protect is not working for people or the planet." -- Catherine Abreu, Climate Action Network Canada
ORNL worked with technology licensee Vertimass and researchers at 10 other institutions on a technoeconomic and a life cycle sustainability analysis of the process -- single-step catalytic conversion of ethanol into hydrocarbon blendstocks that can be added to jet, diesel, or gasoline fuels to lower their greenhouse gas emissions. This new technology is called Consolidated Dehydration and Oligomerization (CADO).CADO.
The analysis, published in Proceedings of the National Academy of Sciences, showed that this single-step process for converting wet ethanol vapor could produce blend-stocks at $2/gigajoule (GJ) today and $1.44/GJ in the future as the process is refined, including operating and annualized capital costs. Thus, the blend-stock would be competitive with conventional jet fuel produced from oil at historically high prices of about $100/barrel. At $60/barrel oil, the use of existing renewable fuel incentives result in price parity, the analysis found.
The conversion makes use of a type of catalyst called a zeolite, which directly produces longer hydrocarbon chains from the original alcohol, in this case ethanol, replacing a traditional multi-step process with one that uses less energy and is highly efficient. The conversion operation could be integrated into new biofuels plants or installed as bolt-on technology to existing ethanol plants with minimal new capital investment, the researchers noted.
The project was supported by the Center for Bioenergy Innovation at ORNL, which in turn is supported by the DOE Office of Science. Scale-up R&D were supported in part by the DOE Office of Energy Efficiency and Renewable Energy and by Vertimass.

The initiative is a DOE-wide effort comprising EERE, the Office of Fossil Energy (FE), the Office of Science, and the National Laboratories. The initiative helps to leverage the National Laboratories' high performance computing capabilities to address challenges in manufacturing and materials through state-of-the-art modeling, simulation, and data analysis. Lawrence Livermore National Laboratory (LLNL) leads the HPC4EI program along with partner laboratories Argonne, Lawrence Berkeley, Los Alamos, Oak Ridge, Pacific Northwest and Sandia National Laboratories, as well as the National Renewable Energy Laboratory and National Energy Technology Laboratory. Funded projects include:
Within the High Performance Computing for Materials (HPC4Mtls) Program, EERE's Vehicle Technologies Office has selected two projects:
The rice-to-biofuel (R2B) project will produce biogas for energy and fertilizer using anaerobic digestion reactors with biomethane upgrading equipment. The activities of the "village scale" pilot facility and the development of the associated business models are supported by academic lab work and analysis from the UK research partners.

One project, led by Dr Jin Xuan, a Senior Lecturer in Low Carbon Processes, will examine the role of e-biofuel in reducing emissions and increasing the sustainability of the road transport sector while enhancing renewable energy security. The research will examine the feasibility of a novel electrochemical process to produce biofuels while reusing the captured CO2.
The project will develop a new concept of e-biofuel which combines the advantages of both e-fuel (produced from renewable electricity and CO2) and biofuel (produced from biomass) to intensively decarbonise the road transport sector. It also provides Loughborough researchers with a new link to the Supergen Bioenergy Hub and the Department of Transport.
A second project led by Dr Tanja Radu, a Lecturer in Water Engineering, will research algae-based biomethane fuel purification and carbon sequestration. The project aims to develop and assess an innovative process for the simultaneous production of high-purity biomethane as a potential natural gas vehicle fuel, together with the sequestration of remaining biomass and biogas carbon into algal co-product and biochar.
The Supergen Bioenergy Hub at Aston University aims to bring together industry, academia and other stakeholders to focus on the research and knowledge challenges associated with increasing the contribution of UK bioenergy to meet strategic environmental targets in a coherent, sustainable and cost-effective manner.
