Global energy production, storage and transport are both essential and environmentally impactful. New energy sources, managing and capturing the biproducts of energy expenditure, and repurposing of carbon dioxide are issues of national and global importance. Researchers at LLNL continue to broadly invent novel technologies that intersect at materials, mechanical, electrical, biological and chemical interfaces. Inventions in this portfolio range from bioreactors, to materials, to batteries, motors and new systems.

R&D World Magazine recently announced their 2022 award winners. LLNL researchers received three awards, which include Tailored Glass by Direct Ink Writing, novel compression gratings that enable a new class of high-energy laser systems and a 3D printing feedstock known as Energy Inks that can print a functioning battery.
Lawrence Livermore National Laboratory has developed GridDS — an open-source, data-science toolkit for power and data engineers that will provide an integrated energy data storage and augmentation infrastructure, as well as a flexible and comprehensive set of state-of-the-art machine-learning models.
LLNL, Penn State, Columbia University, Tufts University, University of Kentucky, Purdue University and industry partner Western Rare Earths will use microbial and biomolecular engineering to develop a scalable bio-based separation and purification strategy for rare-earth elements
This technology can replace combustion heat with renewable energy in the form of electricity from variable renewable energy (VRE), such as photovoltaic (PV) solar and clean hydrogen (H2). Granular media functions as a heat-storage medium that enables renewable energy to be time-shifted from when it is available to when it is needed by an industrial process. The heated…
The novel LLNL approach is to use projection microstereolithography (LAPµSL), starting with a photocurable methacrylate resin formulation consisting of a combination of a photoinitiator, photoabsorber, inhibitor, solvents, and other additives. Prior to use, the resin is pretreated to control viscosity for easier handling. The resin is fed to a LAPµSL printer which…
This technology is specifically focused on optimizing the production of heat with renewable energy and cleaner ways of using fossil fuels. The technology can be used to generate carbon neutral or carbon-negative heat for the following industrial applications (1) clean hydrogen (H2) production by steam methane reforming (SMR) and water-gas shift and (2) fractional…
The inventors have developed a 3% Yttria partially-stabilized Zirconia (3YZ) ceramic ink that produces parts with both nano and microporosity and is compatible with two AM techniques: DIW and projection microstereolithography (PμSL). The 3YZ nano-porous ceramic printed parts had engineered macro cavities measuring several millimeters in length, wall thicknesses ranging…
Earth Battery Energy Storage replaces air-combustion with oxy-combustion, which produces just CO2 and steam, which are easy to separate, thus virtually eliminating more expensive CO2/N2 separation costs. Oxygen from air is produced when the cost of electricity is low. Similarly, all the combustion is done when the cost of electricity is…
This invention describes a multiple nozzle microfluidic unit that allows simultaneous generation streams of multiple layered coaxial liquid jets. Liquids are pumped into the device at a combined flow rate from 100 mL/hr to 10 L/hr. Droplets are created with diameters in the range of 1 µm to 5 mm and can be created with 1-2 shell layers encapsulating fluid. Droplets created…
There are prominent technical challenges arising from spinning a battery on the order of kilohertz as required by magic angle spinning in order to obtain spectral resolution that are addressed and enable operando solid-state NMR. The operando NMR measurement allows for continuous monitoring of the battery components and of potential metastable states that may exist during…
Using native bacterial regulatory systems, LLNL researchers have developed whole-cell biosensors that can be used in aqueous samples for sensitive and selective in situ detection of the uranyl oxycation (UO22+), the most toxic and stable form of U in oxygenated environments. Specifically, two functionally independent, native U-responsive regulatory systems, UzcRS and UrpRS, were integrated…
LLNL has a patented process to produce colloidal silica directly from geothermal fluids. Livermore’s process uses membranes to produce a mono-dispense slurry of colloidal silica particles for which there are several applications. LLNL has demonstrated that colloidal silica solutions that result from extraction of silica from geothermal fluids undergo a transition to a solid gel over a range of…
Livermore Laboratory researchers have developed a methodology for degradation of TBP using an inexpensive, readily available, and environmentally friendly salt, potassium iodide (KI), in a similarly inexpensive, abundant, and green solvent dimethylsulfoxide (DMSO) to efficiently convert TBP to the potassium salts of dibutylphosphate (DBP) and monobutylphosphate (MBP) The reaction is carried…
The core innovation of LLNL's enzyme-embedded, multi-component polymer-based bioreactors perform one or more additional functions of the bioreactor:
- efficient distribution of reactants and removal of products
- exposure of enzymes to high concentrations of gas-phase reactants
- separation of products and reactants
- formation of high surface area…
LLNL’s invention for non-destructive evaluation of water ingress in photovoltaic modules uses a non-invasive optical detection technique based on hyperspectral near infrared imaging technology with frequencies tuned to water absorption band. In this way a quantitative 2D image of the water content in a given device can be obtained remotely and repeatedly over time. A key challenge is presented…
A ceramic HEPA filter designed to meet commercial and DOE requirements, as well as to minimize upgrade installation logistics for use in existing facilities. Current key performance requirements are described in DOE Standard 3020. The ceramic filter is designed to be nonflammable, corrosion resistant, and compatible with high temperatures and moisture. The ceramic filter will significantly…

The fully automated, computer-controlled manifold system allows analysis of the full suite of noble gases (3He/4He, He, Ne, Ar, Kr, and Xe concentrations), along with low level…
LLNL has developed a new method of separating carbon dioxide from flue gas. LLNL's ion pump method increases the concentration of dissolved carbonate ion solution. This increases the vapor pressure of carbon dioxide gas, permitting carbon dioxide to be removed from the downstream side of the ion pump as a pure gas. The ion pumping may be obtained from reverse osmosis, electrodialysis, or the…

An invention at LLNL uses a mixture of solid and liquid dielectric media. This combination has properties that are an improvement over either separately. The solid phase, in the form of small pellets, inhibits fluid motion, which reduces leakage currents, while the liquid phase (dielectric oil) provides self-repair capabilities. Also, since the media is removable, the high voltage equipment…
