What Is Still Limiting the Deployment of Cellulosic Ethanol? Analysis of the Current Status of the Sector
applied sciences Review What is still Limiting the Deployment of Cellulosic Ethanol? Analysis of the Current Status of the Sector Monica Padella *, Adrian O’Connell and Matteo Prussi European Commission, Joint Research Centre, Directorate C-Energy, Transport and Climate, Energy Efficiency and Renewables Unit C.2-Via E. Fermi 2749, 21027 Ispra, Italy; [email protected] (A.O.); [email protected] (M.P.) * Correspondence: [email protected] Received: 16 September 2019; Accepted: 15 October 2019; Published: 24 October 2019 Abstract: Ethanol production from cellulosic material is considered one of the most promising options for future biofuel production contributing to both the energy diversification and decarbonization of the transport sector, especially where electricity is not a viable option (e.g., aviation). Compared to conventional (or first generation) ethanol production from food and feed crops (mainly sugar and starch based crops), cellulosic (or second generation) ethanol provides better performance in terms of greenhouse gas (GHG) emissions savings and low risk of direct and indirect land-use change. However, despite the policy support (in terms of targets) and significant R&D funding in the last decade (both in EU and outside the EU), cellulosic ethanol production appears to be still limited. The paper provides a comprehensive overview of the status of cellulosic ethanol production in EU and outside EU, reviewing available literature and highlighting technical and non-technical barriers that still limit its production at commercial scale. The review shows that the cellulosic ethanol sector appears to be still stagnating, characterized by technical difficulties as well as high production costs. -
Providing Incentives for Bio-Energy While Protecting Established Biomass-Based Industries1 2
POTENTIAL IMPACTS OF CLIMATE AND ENERGY POLICY ON FOREST SECTOR INDUSTRIES: PROVIDING INCENTIVES FOR BIO-ENERGY 1 2 WHILE PROTECTING ESTABLISHED BIOMASS-BASED INDUSTRIES 3 DR. JIM BOWYER DOVETAIL PARTNERS, INC. JUNE 2011 1 The work upon which this publication is based was funded in whole or in part through a grant awarded by the Wood Education and Resource Center, Northeastern Area State and Private Forestry, U.S. Forest Service. 2 In accordance with Federal law and U.S. Department of Agriculture policy, this institution is prohibited from discriminating on the basis of race, color, national origin, sex, age or disability. To file a complaint of discrimination, write USDA Director, Office of Civil Rights, Room 326-W, Whitten Building, 1400 Independence Avenue SW, Washington, DC 20250-9410 or call 202-720-5964 (voice and TDD). USDA is an equal opportunity provider and employer. 3 Bowyer is Professor Emeritus, University of Minnesota Department of Bioproducts and Biosystems Engineering, and Director of the Responsible Materials Program within Dovetail Partners. Executive Summary Current and proposed climate and energy policy, and specifically incentives for the development of bioenergy have the potential to negatively impact established biomass- based industries through increased costs, competition for supplies, and perhaps other unidentified cause and effect relationships. This report assesses short and long-term impacts (both positive and negative) of state and federal climate and bioenergy policies and incentives on the domestic forestry/wood products sector, and in particular the logging, lumber, composite panels, and paper industries, and considers how incentive programs might be modified so as to achieve optimum results for bioenergy producers and established wood-based industries alike. -

The Role of Reforestation in Carbon Sequestration
New Forests (2019) 50:115–137 https://doi.org/10.1007/s11056-018-9655-3 The role of reforestation in carbon sequestration L. E. Nave1,2 · B. F. Walters3 · K. L. Hofmeister4 · C. H. Perry3 · U. Mishra5 · G. M. Domke3 · C. W. Swanston6 Received: 12 October 2017 / Accepted: 24 June 2018 / Published online: 9 July 2018 © Springer Nature B.V. 2018 Abstract In the United States (U.S.), the maintenance of forest cover is a legal mandate for federally managed forest lands. More broadly, reforestation following harvesting, recent or historic disturbances can enhance numerous carbon (C)-based ecosystem services and functions. These include production of woody biomass for forest products, and mitigation of atmos- pheric CO2 pollution and climate change by sequestering C into ecosystem pools where it can be stored for long timescales. Nonetheless, a range of assessments and analyses indicate that reforestation in the U.S. lags behind its potential, with the continuation of ecosystem services and functions at risk if reforestation is not increased. In this context, there is need for multiple independent analyses that quantify the role of reforestation in C sequestration, from ecosystems up to regional and national levels. Here, we describe the methods and report the fndings of a large-scale data synthesis aimed at four objectives: (1) estimate C storage in major ecosystem pools in forest and other land cover types; (2) quan- tify sources of variation in ecosystem C pools; (3) compare the impacts of reforestation and aforestation on C pools; (4) assess whether these results hold or diverge across ecore- gions. -

Thus, the substances classified as fuel must necessarily contain one or several of the combustible elements : carbon, hydrogen, sulphur, etc. In the process of combustion, the chemical energy of fuel is converted into heat energy. To utilize the energy of fuel in most usable form, it is required to transform the fuel from its one state to another, i.e. from solid to liquid or gaseous state, liquid to gaseous state, or from its chemical energy to some other form of energy via single or many stages. In this way, the energy of fuels can be utilized more effectively and efficiently for various purposes. Objectives After studying this unit, you should be able to • describe the classification of fuels, • explain the various types of fuels and their characteristics, and • know their applications in various fields. -
1 Estimating Profitability of Two Biochar Production Scenarios
Estimating Profitability of Two Biochar Production Scenarios: Slow Pyrolysis vs. Fast Pyrolysis Tristan R. Brown1 *, Mark M. Wright2, 3, and Robert C. Brown2, 3 Iowa State University 1Biobased Industry Center 2Department of Mechanical Engineering 3Center for Sustainable Environmental Technologies * [email protected] Iowa State University Ames, IA 50011 Tel: (515) 460-0183 Fax: (515) 294-6336 ABSTRACT We estimate the profitability of producing biochar from crop residue (corn stover) for two scenarios. The first employs slow pyrolysis to generate biochar and pyrolysis gas and has the advantage of high yields of char (as much as 40 wt-%) but the disadvantage of producing a relatively low-value energy product (pyrolysis gas of modest heating value). The second scenario employs fast pyrolysis to maximize production of bio-oil with biochar and pyrolysis gas as lower-yielding co-products. The fast pyrolysis scenario produces a substantially higher value energy product than slow pyrolysis but at the cost of higher capital investment. We calculate the internal rate of return (IRR) for each scenario as functions of cost of feedstock and projected revenues for the pyrolysis facility. The assumed price range for delivered biomass feedstock is $0 to $83 per metric ton. The assumed carbon offset value for biochar ranges from $20 per metric ton of biochar in 2015 to $60 in 2030. The slow pyrolysis scenario in 2015 is not profitable at an assumed feedstock cost of $83 per metric ton. The fast pyrolysis scenario in 2015 yields 15% IRR with the same feedstock cost because gasoline refined from the bio-oil provides revenues of $2.96 per gallon gasoline equivalent. -
Biomass Basics: the Facts About Bioenergy 1 We Rely on Energy Every Day
Biomass Basics: The Facts About Bioenergy 1 We Rely on Energy Every Day Energy is essential in our daily lives. We use it to fuel our cars, grow our food, heat our homes, and run our businesses. Most of our energy comes from burning fossil fuels like petroleum, coal, and natural gas. These fuels provide the energy that we need today, but there are several reasons why we are developing sustainable alternatives. 2 We are running out of fossil fuels Fossil fuels take millions of years to form within the Earth. Once we use up our reserves of fossil fuels, we will be out in the cold - literally - unless we find other fuel sources. Bioenergy, or energy derived from biomass, is a sustainable alternative to fossil fuels because it can be produced from renewable sources, such as plants and waste, that can be continuously replenished. Fossil fuels, such as petroleum, need to be imported from other countries Some fossil fuels are found in the United States but not enough to meet all of our energy needs. In 2014, 27% of the petroleum consumed in the United States was imported from other countries, leaving the nation’s supply of oil vulnerable to global trends. When it is hard to buy enough oil, the price can increase significantly and reduce our supply of gasoline – affecting our national security. Because energy is extremely important to our economy, it is better to produce energy in the United States so that it will always be available when we need it. Use of fossil fuels can be harmful to humans and the environment When fossil fuels are burned, they release carbon dioxide and other gases into the atmosphere. -
