Dr. Pavel Kabat: Reconciling Economic Development and Environmental Sustainability

February 28, 2017 — "Single-disciplinary science alone cannot adequately underpin policies and solutions to resolve major sustainability challenges," according to Dr. Pavel Kabat, Director General and CEO of the International Institute for Applied Systems Analysis (IIASA), a JISEA Research Affiliate. Earlier this month, JISEA hosted Professor Kabat at the National Renewable Energy Laboratory, where he spoke to a group of researchers and analysts about a systems approach to sustainability and IIASA's Global Energy Assessment (GEA). Released in 2012, the GEA links energy to climate, air quality, human health and mortality, economic growth, urbanization, water, land use, and other factors. The United Nations' Sustainable Development Goal (SDG) number 7—Affordable and Clean Energy—uses the GEA as a primary scientific underpinning.

Professor Kabat is also full professor of Earth System Science at Wageningen University in the Netherlands, founding chair and director of the Royal Dutch Academy of Sciences and Arts Institute for Integrated Research on the Wadden Sea Region (the Wadden Academy), a member of the Leadership Council for the UN Sustainable Development Solutions Network, and co-founder of the high-level Alpbach — Laxenburg Group. The latter brings global leaders from academia, governments, businesses, and civil society together to support and advocate for sustainable transitions and sustainable development. Trained as a mathematician and hydrologist, Professor Kabat's almost-30-year research career has covered earth system science and global change, with a specific focus on land-atmosphere interactions, climate hydrology, the water cycle, and water resources. He is an author and coauthor of over 300 refereed publications (including 9 books), a member of 3 international editorial boards, and (co)editor of numerous special issues of peer-reviewed international journals. He has also contributed as lead author and review editor to the assessment reports of the Intergovernmental Panel on Climate Change, which was a co-recipient of the Nobel Peace Prize in 2007.

Nuclear-Renewable Hybrid Energy Systems Can Reduce Greenhouse Gas Emissions from Industry and Support the Power System

December 8, 2016 — Nuclear-renewable hybrid energy systems (N-R HESs) can enable low-carbon, on-demand electricity while providing reduced-emission thermal energy for industrial processes. However, the economic feasibility of these systems may depend on future natural gas prices, electricity market structures, and clean energy incentives. N-R HESs are physically coupled facilities that include both nuclear and renewable energy sources and produce electricity and another product such as a fuel, thermal energy, hydrogen, and desalinated water. Energy and materials flows among energy production and delivery systems are dynamically integrated so that the production rate of each product can be varied.

A series of new reports from the Joint Institute for Strategic Energy Analysis (JISEA) and Idaho National Laboratory (INL) examines various hybrid system configurations to provide a basis to identify opportunities for clean energy use and examine the most economically viable configurations.

In one report, Generation and Use of Thermal Energy in the U.S. Industrial Sector and Opportunities to Reduce its Carbon Emissions, researchers from INL and the Energy Department's National Renewable Energy Laboratory (NREL) identify key greenhouse gas (GHG) emission sources in the industrial sector and propose low-emitting alternatives using targeted, process-level analysis of industrial heat requirements. The report examines emissions generated during process heat generation from the industrial sector. The study focuses on the 14 industries with the largest emissions as reported under the Environmental Protection Agency's Greenhouse Gas Reporting Program in 2014. Approximately, 960 plants from those industries represent less than one half of one percent of all manufacturing in the U.S., but they emit nearly 25 percent of all industrial sector emissions—5 percent of total U.S. GHG emissions in 2014. The report also identifies non-GHG-emitting thermal energy sources that could be used to generate heat without emissions. Those potential sources include small modular nuclear reactors, solar heat for industrial processes, and geothermal heat. The report identifies potential opportunities for each source, identifies implementation challenges, and proposes analyses to identify approaches to overcome the challenges.

In a second report, Status on the Component Models Developed in the Modelica Framework: High-Temperature Steam Electrolysis Plant & Gas Turbine Power Plant, INL details a modeling and simulation framework to assess the technical and economic viability of an N-R HES. INL, with support from Oak Ridge National Laboratory and Argonne National Laboratory, developed a dynamic, physics-based modeling capability of N-R HESs using the Modelica programming language. The report presents details on newly developed high-temperature steam electrolysis (for hydrogen production) and gas turbine power plant subsystems. Simulations of several case studies show that the suggested control scheme could maintain satisfactory plant operations even under rapid variations in net load. The study finds that the N-R HESs modeled could provide operational flexibility to participate in energy management at the utility scale by dynamically optimizing the use of excess plant capacity.

In a third report, The Economic Potential of Three Nuclear-Renewable Hybrid Energy Systems Providing Thermal Energy to Industry, NREL researchers explore the economics of an N-R HES that sells a thermal product (steam or a high-temperature heat transfer fluid) to one or more industrial customers. Under each scenario examined, the economically optimal system configuration includes a nuclear reactor generating a thermal product such as steam or a heat transfer fluid — a configuration that can economically reduce GHG emissions from industry. In addition, configurations that include a thermal power cycle can support resource adequacy for the electricity grid while maximizing production of the thermal energy product if the markets sufficiently incentivize that option.

Together, these three reports indicate nuclear renewable hybrid energy systems can reduce industrial emissions and support the power system.

May 4 Webinar Discusses Spatiotemporal Considerations in Energy Decisions

View slides

Energy-related projects are developed in evolving natural and political environments, and their impacts and economics are neither fixed in time nor distributed evenly in space. Energy and environmental research has often focused on snapshots of particular regions, as many evaluation tools do not consider spatiotemporal factors. The gap in understanding such factors poses a significant challenge for those evaluating energy decisions. For example, the water-energy nexus becomes increasingly significant for decision support when local resources are scarce, yet technology assessments typically do not consider spatiotemporal variability across regions. The costs associated with environmental mitigation can and often do differ by region as well as over time. Climate-related policies are developed according to a region's political influences even as greenhouse gas emissions vary geographically according to several factors, such as available resources, the technology in use, the vintage of the existing infrastructure, and local climate. Related challenges involve comparing the land use of energy technologies when impacts are locally dependent and comparing spatial requirements of renewable and non-renewable projects over time. In this webinar, we will discuss a suite of emerging approaches covering climate, water, and land with the goal of overcoming some of these challenges.

April 13 Webinar to Provide Insights on Natural Gas, Renewable Energy, and the Evolving Power Sector

April 13, 2016 — Natural gas—in combination with other technologies, practices, and policies—is fundamentally reshaping the U.S. power sector. On April 13 at 10 a.m. MDT, researchers from the Joint Institute for Strategic Energy Analysis (JISEA) will present results from three recent studies on natural gas and the U.S. power sector. The first study reviews regional and sectoral trends of natural gas use in the power sector. The second presents scenarios of natural gas as a "bridge" to a decarbonized power system and explores the question of how long we can continue to produce electricity from gas while staying on a path toward long-term climate sustainability. The third study focuses on potential synergies of natural gas and renewable energy in a two-part analysis: the first summarizes key takeaways from a series of regional stakeholder meetings that focused on challenges and opportunities of pairing renewables with natural gas, while the second quantifies the value proposition of investing in the two sources of energy together in specific applications. The presentations will be followed by a question and answer session with the audience. View slides.

Second Report in JISEA Monograph Series Explores Natural Gas as a Bridge to Sustainability

February 16, 2016 — In the second in a monograph series, JISEA examines the role of natural gas as increasingly strict carbon emission targets are imposed on the electricity sector. Do electricity sector trends mean that natural gas can serve as a bridge fuel, replacing the more carbon-intense coal generation in the near term and eventually phasing down in favor of zero-carbon emission resources? This analysis indicates that the answer may depend on the price of natural gas and the level of carbon reduction targets in place. Learn more about the report.
