A presentation for the JISEA annual meeting about circular economy for energy materials including: Focus on energy technologies and their materials; Attention to product design and maintaining/enhancing reliability, durability, performance; Beginning with recycling-focused efforts applied to specific energy technologies, and developing a more comprehensive, integrated strategy.
Wastes generated in shielded hot cells containing materials contaminated with transuranic (TRU) waste present unique problems in waste disposal at Department of Energy (DOE) sites. Reduction of the TRU waste footprint is desirable from a disposal cost perspective due to constraints with RH waste processing and a lack of space availability at the WIPP. Segregation of waste through a pelletized CO2 system provides a viable method this goal.

What does a successful innovation pipeline look like? It starts with fundamental research into properties of materials important for energy technologies, supported by the Basic Energy Sciences (BES) office of DOE. Potentially important discoveries are passed on to applied research supported by DOE’s Energy Efficiency and Renewable Energy (EERE) office, which often partners with or licenses technology to private sector entities. The process usually takes two or three decades, but has repeatedly resulted in the commercialization of new energy technologies.
Environmental management is a key DOE mission, in large part because decades of nuclear weapons production and nuclear energy research have left behind huge quantities of radioactive waste. Most of the radioactivity in the waste, however, comes from the element cesium, which is just a tiny fraction of the total waste. An alert research chemist at Oak Ridge National Laboratory, Bruce Moyer, recognized that if cesium could be removed, dealing with the wastes would be much easier and safer. Moyer also was aware of a potential solution—fundamental research into organic molecules that can recognize and capture metal atoms like cesium, some of it supported by the Basic Energy Sciences (BES) office of DOE. With BES support, he put together a team that, over a decade, showed the potential of this approach. Subsequent support by DOE’s Environmental Management Office allowed the team to work out the practical details.
Semiconductor technology is what has powered the IT revolution, providing ever smaller, less expensive chips. Less well known are newer semiconductor technologies that are transforming the lighting industry and creating super-efficient solar cells to power smart watches, smart buildings, and smart highways. This second semiconductor revolution is based on several decades of fundamental research supported by the DOE Basic Energy Sciences office into the properties of semiconductor materials and applied research by the DOE Energy Efficiency and Renewable Energy office into novel processes for manufacturing practical devices.

The present invention discloses a gasifier and/or a gasification process that provides a long, uniform temperature zone in the gasifier, regardless of the particle size, chemical composition, and moisture content of the fuel by sandwiching a reduction zones between two oxidation zones. The gasifier and/or gasification process has a char that is more energy-dense and almost devoid of moisture that affords for an additional (or char) oxidation zone with a temperature that is higher than a first oxidation zone which is closer to a evaporation and devolatilization zone. As such, the additional (or char) oxidation zone contributes to augmenting the reduction zone temperature, thereby providing a favorable dual impact in improving syngas composition and near-complete conversion of the tar.

An overview of the Co-Optimization of Fuels and Engines Initiative that is bringing together top scientists, engineers, and analysts from nine national laboratories with university and industry partners across the country to investigate fuels and engines as dynamic design variables that can work together to boost efficiency and performance, while minimizing emissions.
This issue of Continuum Magazine covers the depth and breadth of NREL's ever-expanding analytical capabilities. For example, in one project we are leading national efforts to create a computer model of one of the most complex systems ever built. This system, the eastern part of the North American power grid, will likely host an increasing percentage of renewable energy in years to come. Understanding how this system will work is important to its success - and NREL analysis is playing a major role. We are also identifying the connections among energy, the environment and the economy through analysis that will point us toward a 'water smart' future.
Jurisdictions like the City of Los Angeles are boldly establishing ambitious energy objectives—and NREL can be a key partner in informing these transitions.The City of Los Angeles is one of several U.S. local governments setting monumental, measurable goals to transform their energy economies. At the direction of its City Council, LA has embarked on a plan to modernize its electricity system infrastructure—aiming for a 100% renewable energy supply by 2045, along with aggressive electrification targets for buildings and vehicles.
