Bioenergy crop production systems involve complex interactions with the physical environment in which these crops are grown. Plants require water resources and nutrients present in the soil for growth. The expansion of biomass production will require individuals with a thorough understanding of agricultural management practices that are not only economical for producers and growers but also sustain important physical components of the environment such as soil and water. Physical scientists can provide this expertise, using their knowledge of the earth, its components, and its processes to guide important land management decisions. They are also uniquely qualified to work along many other components of the bioenergy supply chain, as their knowledge of the chemical sciences has important applications for the sector’s engineering and manufacturing activities. As such, there are a broad range of pathways that they can follow. Examples of bioenergy related careers in the physical sciences include:

Chemical Scientists
To convert biomass into a biofuel, biomass must first be deconstructed into its component chemicals and then upgraded using various techniques to produce a finished product. There are a suite of chemical reactions that make this process possible and an understanding of the underlying mechanisms behind them is crucial. Chemists fill this essential role by conducting basic and applied research on chemical processes that are used for the production of bio-based fuels and chemicals. They can help understand, control, and optimize various important chemical reactions during biomass conversion or synthesize substances with various specific chemical properties. Once the final product has been produced they can also test the quality of these manufactured goods, to ensure they meet industry specifications.

Hydrologists
A key goal for the bioenergy industry is to enable the sustainable use of water resources throughout the supply chain, from the production of feedstock to its use in biorefineries. Freshwater is an irreplaceable and increasingly scarce resource, and competing needs for irrigation and domestic and industrial water uses demand careful resource planning and monitoring. Hydrologists, hydrogeologists, and water resource specialists study the potential impacts of bioenergy development on water resources and research ways to produce bioenergy feedstocks while also maintaining or improving water quality. They work both in modeling and in the field by collecting data from experiments in watersheds and field stations. They also study the potential to utilize reclaimed water and other non-traditional water sources for the production of biofuels and evaluate the efficiency in water use by different processes and production pathways.

Soil Scientists
Maintaining soil health is a critical element of sustainable bioenergy systems. This includes ensuring that soil nutrients are not depleted by bioenergy cropping, that soil carbon levels are maintained at levels that are environmentally acceptable, that crop residues are harvested in sustainable quantities, and that the appropriate conservation practices are put in place to minimize erosion and leaching of soil and nutrients to water resources. Additionally, bioenergy resources will need to be grown so that they do not negatively impact wildlife. Soil scientists focus on providing stakeholders with recommendations based on research on how to protect natural resources in a conservation area. They are responsible for surveying, staking, information gathering, designing, engineering plan preparation, and construction inspections.

Environmental Scientists
Planning for bioenergy crop landscapes and related infrastructure will require individuals who understand how to minimize the environmental impact of these large-scale projects. Environmental Scientists apply their knowledge of the natural and physical sciences to provide guidance to land managers and business owners on how to minimize impact on the ecosystem and comply with regulations and policies. A common specialization within environmental science is geographic information systems (GIS)—a discipline which focuses on the presentation, management, and analysis of spatial or geographic data. The technical skills that this specialization covers such as spatial analysis, remote sensing, and statistical analysis are highly valuable when executing any geographic aspects of bioenergy planning.

At the senior or supervisory level, senior hydrologists, soil scientists, and environmental scientists will lead management and design efforts on a project or program, overseeing staff and project engineers conducting a wide variety of planning, design, analysis, and research tasks including conceptual designs, engineering reports or studies, detailed designs including drawings and specifications, and cost estimates. A Ph.D. in hydrology, soil science, environmental science, civil or environmental engineering, or a related field is typically required. Significant experience in the field and professional licensure may substitute for additional education. Individuals should demonstrate experience in research, planning, design, and management of leading initiatives. A professional background in the bioenergy sector is highly preferable.

At the senior or supervisory level, senior chemists provide design direction for present and future research and development, including bench scale experimentation and scale up to pilot, demonstration, and commercial scales. They would also oversee various performance testing activities ranging from development to final product qualification testing. A Ph.D. in chemistry, chemical engineering, or a related field is highly preferred. Significant experience in the field and professional licensure may substitute for additional education. Individuals at this level should demonstrate experience through high-level publications and leadership positions. A professional background in the bioenergy sector is highly preferable.
