Fueling America: The Need for Standardization of Solid Biofuels

By Joshua Holmes | February 21, 2012

According to the U.S. DOE’s Billion-Ton Update, more than 500 million tons of solid biomass waste is produced in the U.S. annually, and that figure is estimated to expand beyond 1 billion tons by 2022.
As the country's energy policy evolves and the biomass waste industry continues to grow, solid biofuels will become a staple of American energy. In order for that to occur, biomass energy projects need to continue to be successful, and that requires consideration of several factors.


A successful biomass project should have a well-defined fuel source, as well as properly sized and selected equipment. The primary focus at the front end of every solid biofuels project is identifying the potential feedstock source. Currently, potential biomass sources must always be verified through chemical and physical analysis to ensure the fuel is compatible with the thermal equipment for achieving complete combustion and emissions compliance. Solid biofuels can vary in calorific value, moisture content, and ash content based on class, region, and climate, even on a load-to-load basis. Because of these variations, equipment performance and project economics are at risk of degradation without a proper, uniform definition for solid biofuels.


Currently, domestic feedstock sources are defined by thermal conversion equipment suppliers or by solid biofuel producers, generally according to different terms.  Equipment suppliers are typically focused on a performance-basis, while solid biofuel producers are focused on a value-basis. Unfortunately, this leads to inconsistencies in definitions of solid biofuel quality, quantity, and value, creating uncertainty for both users and providers. This uncertainty creates a level of perceived risk from an economic perspective. 


At the Pacific West Biomass Conference & Trade Show in January, much discussion was focused on the standardization of a solid biofuels definition, with the goal of achieving commoditization. A proper definition on a standardized basis is needed to ensure that the user is able to source compatible solid biofuels of a consistent quality, quantity, and value. The European Commission has developed and implemented standardized specifications and classes for solid biofuels according to CEN/TC 335. They eliminate the ambiguity between users and providers for sourcing and selling solid biofuels. Establishing solid biofuels as commoditized products also allows for a consistent basis of trade throughout the U.S., independent of localized factors.


Universities and energy policy advocates are the most likely candidates to implement this level of standardization in the U.S. The development of terms and definitions is the first step, followed by advocacy and acceptance by the industry. When this occurs, consumers and producers will have a standardized basis to fulfill performance and value requirements while mitigating biomass energy project risks. This will accelerate the growth of the solid biofuel market and effectively utilize the 1 billion tons of solid biomass waste estimated to be produced annually over the next 10 years.

    Centain standardization can be good. However, allow the marketplace cause whatever standardization becomes necessary. Keep government out of the process as long as you can. Remember the historical lessons learned...government will become a drain on innovation and development. Neither politicians or bureaucrats think like entrepreneurs or business people in general. They are only looking to advance their ever-so-personal agendas and line their pockets.

    Commoditization assumes that it is a good idea to ship the biomass. Shipping consumes significant amounts of the energy that the biomass is supposed to produce. Most biomass is a relatively low value energy source, so the more it is handled and processed and shipped, the more energy is consumed. If the biomass is combusted, then even less of its energy is available for conversion into 'useful' energy. This is why most biomass based projects have an energy returned on energy invested (EROEI) value of materially less than one. So you have to ask - why bother? If your goal is energy - not just incineration of a waste stream, and you consume more than you produce, why not just skip it?
