This funding opportunity announcement (FOA) addresses enabling the mobilization of low carbon intensity purpose-grown energy crops across varied agronomic and geographic landscapes through the generation of data and research findings. The FOA seeks applications that will support resource mobilization, including improvements to quality, yield, cost, mechanization of propagation/planting systems, pest management, carbon intensity reduction, ecosystem services, and more from the cultivation of purpose-grown energy crops. Data generated over the course of four to ten years will be used to improve modeling projections, adapt crops and/or crop management strategies to address varying climates, understand variations in soil and belowground carbon storage, quantify ecosystem services, and reduce the carbon intensity for specified purpose-grown energy crop systems.

There is a single Topic Area in this FOA with four Subtopic Areas, each focusing on different feedstock categories. The objective Topic Area 1, Purpose-Grown Energy Crops, is to fund projects that will enable the mobilization of low carbon intensity purpose-grown energy crops across varied agronomic and geographic landscapes through the generation of data and research findings. Each application selected from this FOA will become a member of the larger Regional Biomass Resource Hub Initiative (RBRH) that will work together with the Bioenergy Technologies Office’s (BETO) established Regional Resource Hub Initiative Coordinator, Idaho National Laboratory (INL), to coordinate experimental plans, report data, and collectively achieve the FOA and Initiative objectives. Each submitted application must specify only one of the following Subtopic Areas.

• Subtopic Area 1a: Algae -The objective of Subtopic Area 1a is to support projects that seek to cultivate and harvest as much algae from their given system(s) as possible each year for at least three years. The deliberate cultivation of algae with non-potable water, including all types of microalgae, cyanobacteria, and macroalgae, and algae grown to treat wastewaters is of interest.
• Subtopic Area 1b: Herbaceous Energy Crops – Subtopic Area 1b is centered on enhancing the mobilization of low-carbon intensity herbaceous energy crops across varied agronomic landscapes. For the purposes of Subtopic Area 1b, “herbaceous energy crops” is defined as perennial plants and grasses that live for more than two years and are harvested annually after taking two to three years to reach full productivity. Examples of herbaceous energy crops include, but are not limited to, switchgrass, miscanthus, high-biomass sorghum, wheatgrass, and energycane.
• Subtopic Area 1c: Intermediate Energy Crops – For the purposes of Subtopic Area 1c, “intermediate energy crops” are defined as crops planted between the harvest of a main crop and sowing of the next crop. Typically grown for environmental benefits such as increasing soil carbon or reducing nutrient leaching and soil erosion, intermediate energy crops have the additional potential to be harvested for conversion into low carbon intensity fuels and products.
• Subtopic Area 1d: Short-Rotation Woody Crops – Subtopic Area 1d is focused on enhancing the mobilization of short-rotation woody crops across various geographic landscapes by performing regional field trials to examine long term yield and sustainability. For the purposes of Subtopic Area 1d, “short-rotation woody crops” is defined as fast-growing trees that are harvested within five to eight years of planting. Such trees include, but may not be limited to, species such as, hybrid poplar and shrub willow.
