The Future of Fuels: Meeting Global Decarbonization Goals

Petroleum has served as the source of the vast majority of our transportation fuel for well over a century. During the past few decades, biofuels—primarily ethanol, biodiesel, renewable diesel/jet, and renewable natural gas—have steadily increased in volume though still represent a small portion of the total fuel mix. While initially driven by energy security considerations, recent policies promoting increased biofuel use have been motivated by greenhouse gas reductions. Within the past couple years, significant interest has emerged in “e-fuels”—fuels produced from a carbon source (e.g., CO2) and electricity. If sourced from renewable electrons, e-fuels have the potential to provide significant GHG reductions, though questions of scale and economics remain. This talk will discuss recent research into advanced fuels properties and production routs, as well as issues and challenges that fuels must overcome to power ICEs in the mid 21st century.

Progress Towards Goals Outlined in the 2014 Decadal Vision

The Atmospheric Radiation Measurement (ARM) user facility published its first decadal vision document in 2014 (U.S. DOE 2014a). The overarching vision described in that document was to develop an integrated observation-modeling framework to accelerate the application of ARM observations for process studies and model applications.

Overview of Integrated Pathway Analyses to Meet the Hydrogen Energy Earthshot Goal

This presentation was given at the 2022 Bulk Storage of Gaseous Hydrogen Workshop sponsored by the U.S. Department of Energy's (DOE) Hydrogen and Fuel Cell Technology Office (HFTO). The presentation topics cover the current status of an upcoming NETL publication titled "Comparison of Commercial, State-of-the-Art, Fossil-Based Hydrogen Production Technologies." The study will publicize plant performance, life cycle environmental performance, and the levelized cost of hydrogen (LCOH) production from six fossil-based pathways. The presentation provides preliminary results pending finalization of the study. In addition, the presentation provides an overview of NETL analysis efforts to support the DOE Hydrogen Shot targets.

Seeding picoscale solutions for social macro goals: complex thinking in projects for vulnerable communities

This chapter presents lessons learned from two experiences of implementing sociopoliticalsustainability strategies to achieve environmental and economic sustainability.The projects were carried out in rural communities in Guinea-Bissau andJamaica, which are both vulnerable to climate change. Each experience, developedfrom a systemic perspective and under two frameworks (the water–food–energynexus and ‘Appropriate Technology’), is described in four phases (problemcharacterization, solution design, solution pre-evaluation, and implementation),with the significant findings made by the team in terms of challenges, rewards, andessential conditions for development. Both deal with environment-friendly solutionsthat solve the problems of water and energy provision. Based on complex thinking,the experiences are analyzed from the social inclusion, participation, empowerment,and learning theory viewpoints. Finally, the insights gained by the team arehighlighted: communication requirements, the level of dependency of industrializedsolutions, budget constraints, training, testing, and planning recommendations, thediversity of interaction with the communities, and partners’ skills. As a result, futureactions can exploit these experiences and contribute to the success of subsequentprojects.

Clean Hydrogen: Energy Carrier, Renewables Enabler, and Sector Coupler to Accelerate the Energy Transition and Meet Climate Goals

Comprehensive, concerted efforts supported by the U.S. Department of Energy (DOE), Office of Energy Efficiency and Renewable Energy (EERE), Hydrogen and Fuel Cell Technologies Office (HFTO) are advancing research and development to demonstrate clean hydrogen production and industrial decarbonization pathways. These pathways enable an economically competitive and environmentally beneficial future energy system across sectors and can address specific applications that are difficult to decarbonize. Initiatives include the Hydrogen Energy Earthshot, H2@Scale, National Clean Hydrogen Strategy and Roadmap, H2NEW: Hydrogen from Next-generation Electrolyzers of Water Consortium, HydroGEN: Advanced Water Splitting Materials Consortium, BioH2 Consortium, HyMARC Hydrogen Materials Advanced Research Consortium, and M2FCT: Million Mile Fuel Cell Truck Consortium.

Advancing Clean Energy and Economic Development Goals in Pembroke Hopkins Park Township

Pembroke Hopkins Park Township (PHP) is participating in the U.S. Department of Energy's (DOE) Communities Local Energy Action Program (LEAP) pilot, which is supporting 24 communities across the United States in their efforts to transition to clean energy to improve energy reliability, lower energy costs, and strengthen local economies. Communities LEAP is specifically open to low-income, energy-burdened communities that are also experiencing either direct environmental justice impacts or direct economic impacts by moving towards clean energy solutions.

More Than Recycling: How Should We Define Circularity Goals for PV in a Global Energy Transition? Preprint

Energy transition to carbon-free electricity is a crucial pillar of the Circular Economy. Renewable energy reduces environmental impacts and decarbonizes the production of other goods. But, manufacturing renewable energy sources, such as photovoltaic (PV) modules, require energy inputs that are currently carbon intensive. So, how do we decarbonize and circularize these critical technologies to achieve a sustainable energy transition? This work proposes that effective capacity-the installed capacity accounting for degradation rates and failures-is a critical metric to evaluate renewable energy technologies on the path toward circular economy and energy transitions. Our analyses also emphasize the importance of examining a suite of metrics incorporating mass and energy flows to identify potential tradeoffs and inform design or lifecycle management decisions holistically.

Cigeo Design Options, Risks and Opportunities Management: A Continuous Project Management Goal - 20015

Andra is currently completing the detailed engineering phase of the stepwise design development of Cigeo, the French HLW and IL-LLW Deep Geological Repository. If licensed in the coming years, Cigeo's progressive construction, industrial operation and closure will last over more than a century. Such a duration, associated with the requirements in terms of reversibility, lead to the choice of an incremental design that allows, for next operator generations, to integrate improvements derived from scientific and technical progress as well as from experience feedback from its operation. This incremental design approach, associated with a permanent risks and opportunities management process, will continue after licensing of Cigeo as a tool for the governance of the reversibility.

Smart Labs: Improving Lab Facilities to Meet Decarbonization Goals

Smart Labs enable safe and efficient world class science to occur in laboratories through high-performance methods. The Smart Labs Toolkit describes a systematic process to help laboratory owners and operators plan, assess, optimize, and manage laboratory facilities. This half-day workshop reviews the four phases of the Smart Labs Toolkit along with an interactive activity to complete a Laboratory Ventilation Risk Assessment. This session will also highlight the Lab Benchmarking Tool, which compares the energy use, emissions, and operational practices of lab buildings with similar facilities. Attendees will also discuss application as well as sharing tools and best practice guides.
