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).

Electrochemical CO2 conversion to valuable fuels and chemicals

LLNL’s researchers use physical vapor deposition (sputter deposition or electron beam deposition) to coat an inert gasket material (i.e. PTFE) with a conductive metal (i.e. copper). The gas diffusion electrode overlaps onto the copper coated gasket to allow for electrical conductivity between the catalyst surface and the flow field/current collector of a CO2 electrolyzer. The coated gasket…

Graphite

LLNL’s innovation offers an alternate synthetic route to graphite at lower cost using a molten salt mixture of CaCl2-CaCO3-CaO.  The synthetic production of graphite and other high-value carbon materials is accomplished in molten salt media via electrochemical reduction and transformation of the carbon from the carbonate ion. The broad electrochemical window of molten salts enables the…

Projection Microstereolithographic Additively Manufactured Anion Exchange Membrane

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 employs a near UV…
