Integrated mid-continent stacked carbon storage hub, Phase I Final Report

The final technical report of the Integrated Midcontinent Stacked Carbon Storage Hub (IMSCS-HUB). Describes the projects tasks and results of a Phase I prefeasibility study for commercial-scale carbon storage in Nebraska and Kansas. The project focused on ethanol plants as CO 2 sources in central Nebraska as a CO 2 Supply and stacked-storage oilfields in southwest Nebraska and Western Kansas as storage sites. The results of the work show that the midcontinent United States is ideal for an early commercial-scale project considering the relative ease of CO 2 capture from ethanol plants and the utilization of CO 2 for enhanced oil recovery in combination with saline storage.

Velo: A Knowledge Management Framework for Modeling and Simulation

Modern scientific enterprises are inherently knowledge-intensive. Scientific studies in domains such as geosciences, climate, and biology require the acquisition and manipulation of large amounts of experimental and field data to create inputs for large-scale computational simulations. The results of these simulations are then analyzed, leading to refinements of inputs and models and additional simulations. The results of this process must be managed and archived to provide justifications for regulatory decisions and publications that are based on the models. In this paper we introduce our Velo framework that is designed as a reusable, domain independent knowledge management infrastructure for modeling and simulation. Velo leverages, integrates and extends open source collaborative and content management technologies to create a scalable and flexible core platform that can be tailored to specific scientific domains. We describe the architecture of Velo for managing and associating the various types of data that are used and created in modeling and simulation projects, as well as the framework for integrating domain-specific tools. To demonstrate realizations of Velo, we describe examples from two deployed sites for carbon sequestration and climate modeling. These provide concrete example of the inherent extensibility and utility of our approach.

Knowledge Annotations in Scientific Workflows: An Implementation in Kepler

Abstract. Scientic research products are the result of long-term collaborations between teams. Scientic workfows are capable of helping scientists in many ways including the collection of information as to howresearch was conducted, e.g. scientic workfow tools often collect and manage information about datasets used and data transformations. However,knowledge about why data was collected is rarely documented in scientic workflows. In this paper we describe a prototype system built to support the collection of scientic expertise that infuences scientic analysis. Through evaluating a scientic research eort underway at Pacific Northwest National Laboratory, we identied features that would most benefit PNNL scientists in documenting how and why they conduct their research making this information available to the entire team. The prototype system was built by enhancing the Kepler Scientic Work-flow System to create knowledge-annotated scientic workfows and topublish them as semantic annotations.
