Systems Analysis

DOE/NETL possesses strong systems analysis and policy-support capabilities. Systems analysis in support of the Carbon Capture Program consists of conducting various energy analyses that provide input to decisions on issues such as national plans and programs, resource use, environmental and energy security policies, technology options for research and development programs, and paths to deployment of energy technology. This work includes technology, benefits, and current situation and trends analyses related to CO2emissions control. Systems analyses and economic modeling of potential new processes are crucial to providing sound guidance to R&D efforts. Since the majority of new CO2 capture technologies are still at a bench scale level of development, a conceptual design is first generated with emphasis on mass and energy balances. Based on available data and/or engineering estimates, these systems are optimized, and "what-if" scenarios are evaluated to identify barriers to deployment and help the process developers establish system performance targets. Reports that have been generated describing systems analyses in support of carbon capture efforts are shown in the table below.

Evaluating the Impact of R&D and Learning-By-Doing on Fossil Energy Technology Cost Reductions: There Can be No Learning if There is No Doing
This analysis explores the contributions of R&D prior to deployment and learning-by-doing on fossil energy technology cost reductions. A learning curve analysis tool and cash flow model were constructed for carbon capture, utilization, and storage (CCUS) capital costs to quantify these effects. The results of this analysis show that without CCUS R&D prior to deployment, the opportunity to learn-by-doing does not occur because commercial entry costs are prohibitive.
