Avnos

Avnos is a US-based startup founded in 2020. It is aiming to commercialize its modular hybrid direct air capture (HDAC™) technology.

Blue Current

Blue Current, founded in 2014, emerged from the U.S. Department of Energy's Joint Center for Energy Storage Research with a mission to create safer batteries. Initially focused on safety, the company pivoted in 2016 to develop solid-state composite electrolytes, and by 2018, it introduced a fully dry solid-state battery featuring a high-silicon anode, known as the "silicon elastic composite" battery. Headquartered in Hayward, California, Blue Current expanded its operations in 2019 with a 22,000-square-foot facility and secured over US$30 million in funding by 2022. Multilayer cell demonstrations and pilot-scale production happened in 2023 and 2024. Blue Current works on solving four primary challenges of solid-state batteries: safety, pressure, temperature, and scalability.

Aqua Metals

Will Fuel Cell Electric Vehicles Boom or Bust in the Next 20 years?

While battery electric vehicles (BEVs) continue to grow in model availability, sales numbers, and available charging infrastructure, the same cannot be said about fuel cell electric vehicles (FCEVs). IDTechEx reviews the on-road fuel cell electric vehicle market and assesses whether passenger cars, light commercial vehicles, buses, and medium and heavy-duty trucks will use fuel cell technology in 20 years.

Redwood Materials

Redwood Materials is a Li-ion battery recycler based in the US.

3M: Ionomer Materials

3M are an American multinational conglomerate operating in the fields of industry, worker safety, and consumer goods. 3M provide ionomer material solutions for ion exchange membrane applications in water treatment, chemical production, and emerging green hydrogen applications. This profile focuses on 3M's ionomer products.

Climeworks

Climeworks is a Swiss company developing a modular direct air capture (DAC) technology based on a solid adsorbent system.

New Energy Blue

New Energy Blue processes agricultural residues into second generation biofuels and biochemicals. IDTechEx spoke to Roger Moore, Communications Director & Brand Manager.

Brilliant Matters: OPV

Brilliant Matters is a Canada-based material provider, specializing in materials for organic electronics applications.

Seeo, Inc

Seeo was founded in 2007 by researchers from the Lawrence Berkeley National Laboratory (LBNL), including Nitash Balsara, Hany Eitouni, and Mohit Singh. The company was built on the foundation of a nanostructured solid polymer electrolyte technology developed at LBNL. This technology, later branded as "DryLyte," utilized a block copolymer that combined safety, non-flammability, and high energy density. The solid electrolyte allowed the use of lithium-metal anodes, which offered significantly higher theoretical capacities compared to conventional graphite anodes.

ION Clean Energy

ION Clean Energy is a point-source carbon capture technology provider, focusing on water-lean amine solvents capable of lowering energy demand and subsequently lowering capture costs. CEO Tim Vail presented at the Economist Impact Carbon Capture Summit 2025.

Aspen Aerogels

US-based Aspen Aerogels is the market leader in silica composite aerogel products, founded in 2001. It designs, develops, manufactures, and sells its aerogel blankets.
