Algal Hydrogen Production -- Stand Alone or Integrated System?

Photosynthetic bacteria and green algae photoproduce H2. but do so utilizing different catalysts and substrates. Green algae use reductant generate mostly by water oxidation to catalyze the reduction of protons to H2 gas, while photosynthetic bacteria catalyze H2 production from organic acids using the nitrogenase enzyme. Moreover, these two organisms utilize different regions of the solar spectrum to perform photosynthesis: green algae's light harvesting antenna is comprised of chlorophyll molecules that absorb mostly blue and red light; photosynthetic bacteria harvest blue and far-red light through their light-harvesting pigments to run its non-oxygenic photosynthetic reactions. There is thus an opportunity to increase the range of solar spectrum used to photoproduce H2 by combining the light-harvesting and catalytic properties of these two organisms in a single process. In the current manuscript, we describe an experimental system that validates this hypothesis and demonstrates quantitatively the advantages of a two organism process for production of higher amounts of H2 and thus achieving solar light conversion efficiencies.

Energy Systems Integration Partnerships: NREL + GINER ELX

At current levels of renewable generation there are already periods when the supply of electrical power significantly exceeds the level of demand. The wide penetration of renewable energy sources (RES) requires an energy storage solution which can include hydrogen generated via Polymer Electrolyte Membrane (PEM) electrolysis.

Energy Systems Integration: NREL + BlockCypher

BlockCypher is teaming with NREL to demonstrate secure peer-to-peer energy transactions - taking place in real-time and without a centralized arbitrator - forming the basis for a distributed energy marketplace. The transactions use blockchain technology for features like instantaneous settlement times, low transaction costs, and for enabling trust between participants without the need for a third party. Blockchain technology is an innovative solution to managing grid security, enabling distributed energy markets, and the proliferation of distributed energy resources, all-the-while opening up new value streams for customers and utilities.

Energy Systems Integration: NREL + EATON

Electrification of transportation fleets provides an opportunity for optimizing multiple distributed energy resource (DER) technologies, such as solar and energy storage. NREL is partnering with Eaton to evaluate control strategies for managing electric bus (E-bus) fleets for grid services. The project team will develop a replicable platform for evaluating EV fleet management and quantifying benefits from grid services.

Integrated system for nanofiber production

The invention provides a system for producing nanotubes, nanofibers and nanorods, the system comprising a wire array shaped as a cylinder such that the cylinder defines a void; a first furnace positioned within the void; a second furnace positioned opposite the first furnace to define a channel adapted to receive a portion of the cylinder as the cylinder rotates about its axis; a device for depositing spun fiber onto the wire array as the cylinder rotates; and a device for removing the deposited fiber from the array after the deposited fiber is heated within the channel. The invention also provides a method for producing nanotubes, the method comprising: supplying a cylindrical wire array, wherein the array defines an internal void; positioning a first furnace within the void; positioning a second furnace opposite the first furnace so as to define a channel between the first furnace and second furnace, the channel adapted to receive a portion of the cylindrical array as the array rotates about its axis; depositing spun fiber onto the array as the array rotates; heating the deposited fiber as it enters the channel; and removing the deposited fiber as it exits the channel.

Renewable Energy Technology and Systems Integration for the Oil and Gas Industry

Introduction to the mission and research of the National Renewable Energy Laboratory (NREL) and the Joint Institute for Strategic Energy Analysis (JISEA). JISEA is co-sponsored by industries, governments, and partnered with several academic institutions (see https://www.jisea.org). Presentation will review statistics about the growth of renewable energy and also discuss potential future trends. It will review several specific case studies relevant to the oil and gas industry, including renewable energy for industrial operations and clean technologies and fuels that would be most relevant to oil and gas technologies and capabilities.
