PERFORM

Performance-based Energy Resource Feedback, Optimization, and Risk Management

Optimal utilization of all grid assets requires a fundamental shift in grid management rooted in an understanding of asset risk and system risk. Existing management practices were designed for a grid consisting of and fully reliant on conventional generation assets. Present operational and planning practices do not acknowledge or leverage the true capabilities and associated challenges of emerging assets. A novel risk-driven paradigm will allow emerging assets to be trusted and relied upon to provide the critical products and services necessary to maintain an efficient and reliable grid,…

PETRO

Plants Engineered to Replace Oil

The 10 projects that comprise ARPA-E’s PETRO program, short for “Plants Engineered to Replace Oil,” aim to develop non-food crops that directly produce transportation fuel. These crops can help supply the transportation sector with plant-derived fuels that are cost-competitive with petroleum and do not affect U.S. food supply. PETRO aims to redirect the processes for energy and carbon dioxide (CO2) capture in plants toward fuel production. This would create dedicated energy crops that serve as a domestic alternative to petroleum-based fuels and deliver more energy per acre with less…

REPAIR

Rapid Encapsulation of Pipelines Avoiding Intensive Replacement

Cast iron, wrought iron, and bare steel natural gas distribution pipes—legacy pipes—make up 3% of the nearly 2 million miles of utility pipes in use, but account for a disproportionate number of gas leaks and pipe failures compared to more recently replaced infrastructure. REPAIR seeks to reduce natural gas leaks from these pipes by developing a suite of technologies to enable the automated construction of new pipe inside existing pipe. The new pipe must meet utilities’ and regulatory agencies’ requirements, have a minimum life of 50 years, and have sufficient material properties to operate…

ROOTS

Rhizosphere Observations Optimizing Terrestrial Sequestration

America’s vast terrestrial resources (over 520 million hectares of crop, range and forestland) are strategic assets essential for sustainable economic growth. While advances in technology have resulted in a ten-fold increase in crop productivity over the past hundred years, soil quality has declined, incurring a soil carbon debt equivalent to 65 parts per million (ppm) of atmospheric carbon dioxide (CO2). The soil carbon debt also increases the need for costly nitrogen fertilizer, which has become the primary source of nitrous oxide (N2O) emissions, a greenhouse gas. The soil carbon debt also…
