Energy Options: While use of woody biomass for direct heat or electrical energy production may be appropriate in some local areas of the State, but development of renewable clean sources of transportation fuel should be the State’s highest energy priority. However, a shift from oil to biofuels will not be easy. Efficient conversions of woody biomass to liquid fuels such as ethanol will require large integrated biorefineries dependent upon regular collection of millions of tons of woody biomass each year. In Washington State, 11 million dry tons of forest biomass annually are potentially available for energy production. Additional biomass from municipal waste and agricultural residues can be recovered to augment wood supplies for mixed feedstock conversions. Co-location of integrated biorefineries with pulp and paper mills represents the greatest potential opportunity to economically maximize energy recovery of liquid fuels, electricity, and process steam from biomass resources in Washington State. Co-location with existing facilities will bring reduced capital costs, access to needed infrastructure, synergies for integrated raw materials and product streams, and an engaged corps of highly-skilled engineers and union workers.
An Energy Strategy for the State is needed: Sustainable development of renewable energy alternatives to fossil fuels will require careful planning, resource conservation, and committed policy support. Washington State could greatly benefit from development of a scientifically-supported comprehensive strategy for renewable energy based upon an inventory of available renewable resources, identification of energy conversion priorities, and full understanding of the cost of inaction.
Challenges to progress: Washington does not have a lead Energy Agency or effective organizational framework for scientific participation in policy considerations such as the interrelated topics of energy, climate and sustainable forest resources. Criteria for comparisons of potential alternative energy and resource applications have not been developed to inform State energy policy priorities. For example, should biomass be used for electricity generation vs. transportation fuels? The public benefits of carbon neutral energy alternatives to fossil fuels are not readily captured by consumer markets and, in lieu of integrated planning, are not adequately characterized in State energy policy. Current State energy policies, such as I-937, inadvertently favor small-scale and inefficient conversions of biomass to electricity, which fail to address energy independence, have poor raw material-to-energy yields and result in unintended consequences such as compromised biofuels development and reduced greenhouse gas emissions. A comprehensive energy plan is needed.
Recommendations:
A lead state agency should be given authority to coordinate policy development for the interrelated energy policy imperatives of climate change mitigation, energy independence and sustainable management of State natural resources. An interdisciplinary team of State scientists should be assembled to recommend energy priorities and strategic opportunities for progress based upon the three imperatives. Progress will be dependent upon effective use of available but finite resources that maximize energy yields from efficient conversions of biomass to biofuels. Large-scale biofuels projects rather than inefficient small-scale power generators are needed. A State commitment to develop a comprehensive energy strategy supported by interdisciplinary research to identify priority objectives will be needed to support investment for Wood to Energy in Washington.
Climate Change: Policy mechanisms, such as a carbon tax, to provide economic value for energy projects that reduce greenhouse gas emissions are needed.
Energy Independence: An assessment of costs and benefits that could derive from reduced reliance upon imported fossil fuels in Washington resulting from development of wood biomass for ethanol should be conducted.
Forest Health: Washington will benefit from a plan to integrate hazardous fuel load reductions for forest health with provision of adequate woody biomass resources for effective climate change mitigation and energy development activities.
Guidelines for Slash Removal: As evidenced by successes in other states, forest biomass collection guidelines should be developed and incorporated into Washington forest practice rules.
Integrated Infrastructure and Product Hierarchies: Biomass energy priorities should favor liquid fuels conversions at biorefineries that can optimize energy yields through integrated recovery of biofuels, heat, electricity, and chemical byproducts. Where available, biorefineries will be best sited to exploit synergies with pulp and paper mills. State investments in support of biorefinery development would be the most effective biomass-to-energy approach for response to the three imperatives of climate change mitigation, energy independence, and sustainability.
Conversion Technology Advancement: Continued research investment to develop superior conversion technologies for liquid fuel production from Washington biomass resources will help to identify advancements that provide maximum energy yields at least costs. Investment in a pilot project towards development and demonstration of a commercial, integrated biorefinery is highly recommended as an important next step.
Social License: Outreach programs that facilitate public education and dialogue towards consensus solutions to contemporary resource and energy challenges are worthy of State support, as demonstrated in many other states.
Green Jobs: State leaders should acknowledge that wood is a preferable green building product and that forest biomass-to-energy can be a cornerstone element of a clean future economy. State agencies should work with universities and community colleges to establish training programs for forestry workers that cover the spectrum of skills from collection through conversion.
Green Building Products: Green building standards should be revised such that product comparisons are based upon rigorous scientifically-supported performance standards such as Life Cycle Assessment and Net Energy Balance.
Interdisciplinary Science Support for Energy Policy Development: Programmatic investment in sustained in-state interdisciplinary research to develop the data and inform policy makers and stakeholders of realistic and effective strategies to address the difficult and complex challenges of renewable energy development and climate change will be essential. The University of Washington has recently organized a new College of the Environment to address such tasks. Important energy research is also being conducted at Washington State University, the Pacific Northwest National Laboratory, and other State institutions of scholarly pursuit but an effective organizational framework for critical review and collaboration between research institutions is needed.
