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.

Lab scientists win four 2025 R&D 100 awards

The trade journal R&D World Magazine recently announced the winners of the awards, often called the “Oscars of innovation,” recognizing new commercial products, technologies and materials that are available for sale or license for their technological significance.

Lawrence Livermore National Laboratory (LLNL) scientists and engineers have earned four awards among the top 100 inventions worldwide.  With this year’s results, the Laboratory has now collected a total of 186 R&D 100 awards since 1978. 

Submitted through LLNL’s Innovation and Partnerships Office (IPO), these awards recognize the impact that Livermore innovation, in collaboration with industry partners, can have on the U.S. economy as well as globally.

Carbon nanotube ‘smart windows’ offer energy savings

A multidisciplinary team of researchers at Lawrence Livermore National Laboratory (LLNL) developed a new type of electrically controlled, near-infrared smart window that can cut near-infrared light transmission by almost 50%. Their secret ingredient? Vertically aligned carbon nanotubes—tiny, tube-shaped structures made from carbon atoms that are thousands of times thinner than a human hair. The research was published in Nano Letters.

LLNL and Verne demonstrate highly efficient hydrogen-densification pathway with less required energy

LLNL and Verne have demonstrated a novel pathway for creating high-density hydrogen through a research program funded by Department of Energy’s ARPA-E.  The demonstration validated that it is possible to efficiently reach cryo-compressed hydrogen conditions with liquid hydrogen-like density directly from a source of gaseous hydrogen.

Verne began working with LLNL in 2021 through a Strategic Partnership Project to test Verne’s tanks at LLNL’s cryogenic hydrogen fueling facility. Collaborations progressed through two Cooperative Research and Development Agreements in 2023-24 facilitated by LLNL’s Innovation and Partnerships Office (IPO).

LLNL researchers have developed additive manufactured fuel targets for IFE.  They have been successful in using TPL to fabricate low density (down to 60 mg/cm3) and low atomic number (CHO) polymeric foams for potential targets, and some have been tested at the OMEGA Laser Facility. With TPL, LLNL researchers have also been able to fabricate a full fuel capsule with diameter of ~ 5mm or…

LLNL energy grid protection device

The approach is to leverage the fact that a momentary “load” equal to the power transmission line impedance, (Z0), during the transient can suppress its propagation.  Z(0) is typically a fixed impedance of several hundred ohms based on the geometry of most single wire transmission lines.

So, an isolated self-powered opticondistor (OTV) system may provide an ultrafast method of…

JFET Device Structure

LLNL’s novel approach is to use diamond substrates with the desired donor (nitrogen) and acceptor (boron) impurities.   In order to optically activate these deep impurities, the invention requires at least one externally or internally integrated light source.  The initial exposure to light can set up the desired conduction current, after which the light source could be turned…

Electrodeposition of Zn onto 3D printed copper nanowire (CuNW)

Improving the active material of the Zn anode is critical to improving the practicality of Zn-MnO2 battery technology. LLNL researchers have developed a new category of 3D structured Zn anode using a direct-ink writing (DIW) printing process to create innovative hierarchical architectures.  The DIW ink, which is a gel-based mixture composed of zinc metal powder and organic binders, is…
