Techno-Economic Models are Instrumental in Analyzing Decarbonization Strategies

This presentations provides a high-level overview of the NETL-developed techno-economic models associated with the CO2 transport and CO2 storage components of the carbon capture and storage (CCS)/carbon capture, utilization, and storage (CCUS) value chain. It also discusses the models’ capabilities through the discussion of select modeling applications (both internal and external) and highlights current model modifications and future work. It was presented at the CCUS 2023 conference, organized and presented by the Society of Petroleum Engineers (SPE), American Association of Petroleum Geologists (AAPG), and Society of Exploration Geophysicists (SEG) and held in Houston, Texas, April 25-27, 2023.

NETL’s Techno-Economic Modeling Resources for Analyzing Decarbonization Strategies Using CCUS

NETL has developed techno-economic models to evaluate the performance characteristics and cost drivers for elements of the carbon capture, utilization, and storage (CCUS/CCS) value chain: CO2 capture, CO2 pipeline transport, CO2 saline storage, and oil production and CO2 storage using CO2 enhanced oil recovery (EOR). These tools can be used individually to evaluate the economic opportunity for specific CCUS components, or they can be used in tandem to assess integrated CCUS systems. An overview and high-level description of the transport and storage models is presented in a poster along with useful outputs that can be generated with each.

Energy Efficiency's Role in Industrial Decarbonization

Around the world, efforts are increasing to drastically reduce greenhouse gas (GHG) emissions by 2050. The goal of the Paris Agreement is to hold the increase in global average temperature rise to below 2°C as compared with preindustrial levels, specifically aiming to limit it to 1.5°C. As of 2017, the global average temperature rise reached approximately 1°C. It is expected to hit the 1.5°C mark by 2040 if current trends continue. Limiting temperature rise to 2°C will require reaching net zero emissions in the latter half of the 21st century; GHG emissions would need to reach a near-zero value by 2050 to limit the rise to 1.5°C.

Multi factor Assessment for Decarbonization via Technically Viable Carbon Storage

Final poster presenting research under EDX4CCS portfolio, Task 21, on multi-factor assessment for technically viable carbon storage. To date, carbon storage viability assessments have focused on the technically recoverable storage resources to estimate the volume of carbon storage in reservoirs targeted for geologic carbon sequestration. The Carbon Storage Technical Viability Approach (CS TVA) was developed to account for all factors determining the viability of carbon storage at a given site, including socioeconomic and environmental aspects in addition to the classic subsurface geologic assessment. Abstract accepted to the American Geophysical Union Fall Meeting 2023.

High Temperature Heat Pumps and Their Roles in the Decarbonization of Building and Industry

Heat pumps have been sought as a promising technology for air and water heating processes in buildings. Several OEMs have been commercializing heat pumps with varying capacities; However, the application has been limited to lower temperatures (less than 70℃). With the recently growing interest in replacing gas-fired equipment for buildings and industrial processes, a new class of heat pumps, known as high-temperature heat pumps, is gaining substantial interest where the target temperatures are higher than the conventional heat pump technology (greater than 90℃). The current study is focused on this class of heat pumps and aims to provide a holistic overview of state-of-the-art technology while highlighting major challenges and opportunities. The discussion will be focused on the availability of technology to enable higher sink temperatures, deployment-based applications, waste heat recovery, and process integration and controls.

Workshop: Advanced Metering for Decarbonization: Electric Vehicles and 24/7 Carbon-Free Electricity

The purpose of this workshop is to learn more about advanced metering best practices for meeting the goals of EO 14057. This will be a 2-part session, first part to include presentations on the FEMP best practice work related to metering: 1) Electric Vehicles (EVs) and EV charging station electricity use. 2) Integrating data sources to calculate hourly carbon pollution-free electricity (CFE). Second part will facilitate small group discussions with a problem-solving activity.

New U.S. Data Tools are Playing a Crucial Role in Decarbonizing Buildings at Speed, Scale, and Low Cost

Preparing buildings for retrofits traditionally requires expensive on-site audits or timeintensive simulation models. As a result, the majority of buildings fail to pursue cost-saving retrofits. To address these barriers, the U.S. Department of Energy (DOE) has introduced the Building Efficiency Targeting Tool for Energy Retrofits (BETTER)-a new, free, on-line tool that utilizes a data-driven analytical engine and user-friendly web interface to automatically analyze a building's monthly energy usage in response to weather conditions. The tool benchmarks a building's electric and fossil energy usage against peers; estimates energy, cost, and emissions reductions at the building and portfolio levels; recommends energy efficiency measures; and prioritizes buildings for net-zero energy retrofits. Thanks to interoperability with the DOE's Standard Energy Efficiency Data (SEED) platform, BETTER is supporting U.S. jurisdictions to prepare buildings for retrofit at speed, scale, and low cost to comply with energy policies. This paper discusses the use of BETTER and SEED by one of the branches of the California state government to streamline a retrofit program across 455 public non-residential buildings to align with state goals to reduce greenhouse gas emissions. It describes the organization's challenge to reduce energy consumption across a geographically diverse, aging portfolio; explores how BETTER and SEED improved workflow efficiency; presents preliminary results, including avoiding audit costs of $3.28 million and developing the groundwork for retrofit projects estimated to prevent emission of 2,271 t CO2e annually; and provides guidance for other jurisdictions seeking similar results.
