Clean Energy Technologies for Economic Transitions

Energy systems across the world are undergoing fundamental transformations. Electricity and heat production is becoming cleaner and more distributed, driven by declining energy prices and higher technology efficiencies, as well as a desire to reduce environmental impact. The technologies that produce clean energy, such as solar photovoltaic panels, wind turbines, and lithium ion batteries for vehicles and storage, depend less on fuel costs and more on technology costs and global manufacturing and trade. Therefore, innovations in technology manufacturing, systems integration, and deployment can reduce costs of materials, equipment, labor, operations, and transportation, across all the links in the energy supply chain. The clean energy trends are expected to continue and perhaps grow through expansion of clean energy technologies for industrial and transportation sectors, although there are many possible future scenarios due to the diversity of resources and societal objectives in different communities, countries, and regions. This presentation will summarize the status and potential futures of key clean energy technologies and their manufacturing, deployment, and integration with other energy systems and sectors.

H2@Scale: Hydrogen Integrating Energy Systems

H2@Scale is a concept where hydrogen is an energy intermediate that complements the electricity grid and natural gas system. Hydrogen can be a valuable feedstock for oil and biofuel refining, ammonia production, steel production, and converting carbon dioxide to valuable products due to its chemical properties. It can also be a valuable energy carrier for transportation because it can be fast-filled, stored energy on fuel cell electric vehicles as well as providing storage for the grid. In addition, hydrogen is one of the few non-carbon emitting options to achieve high temperatures needed in industrial processes. If a hydrogen demand is available, hydrogen can be economically produced from variable renewable electricity (e.g., wind, photovoltaic solar) thus increasing the economically viable penetrations of those generation technologies. Likewise, hydrogen is an alternative product that can provide revenue to economically challenged nuclear power plants. This presentation summarizes the demand potential for hydrogen, the technical potential of resources that could be used to produce it, and a number of economic potential scenarios that identify key markets and technology development necessary to compete in them.

Methods and systems for integrating ion manipulation devices

A switch for coupling a first ion manipulation device to a second ion manipulation device comprises a first surface and a second surface, at least one first electrode coupled to each of the first and second surface and configured to receive a first voltage and generate a first potential, and at least one second electrode coupled to each of the first and second surface and configured to receive a second voltage and generate a second potential, wherein the first potential inhibits the motion of ions along a first direction and the second potential inhibits the motion of ions along a second direction different from the first direction.

Multi-barrier wellbore integrity inspection system with eccentricity correction

A downhole inspection system includes a neutron imaging device operable to generate data for detecting potential wellbore anomalies and an electromagnetic imaging device operable to generate data for detecting potential wellbore eccentricity. The neutron imaging device includes a neutron generator operable to emit neutrons, and a neutron detector fixed relative to the neutron generation unit and operable to detect backscattered neutrons from a surrounding environment. The electromagnetic imaging device includes at least one transmitter for generating electromagnetic pulse, and at least one receiver for detecting returning electromagnetic pulse. Correlation of the neutron imaging data with the electromagnetic imaging data provides additional data regarding the potential wellbore anomalies.
