Why Governments Should Back Graphene over Rare Earths

The Rare Earth Problem…

Rare earth elements (REEs) have powered the modern economy for decades. But they are also a strategic liability:

• Geopolitical dependence: Around ninety percent of global refining is concentrated in China.
• Volatility: Price swings disrupt electric vehicle, renewable energy, and defense supply chains.
• Pollution: Toxic refining waste undermines the very climate goals rare earths were meant to serve.

Governments face a choice: expand rare earth mining, or back a cleaner substitute. Graphene, particularly lattice defect free and consistent graphene from HydroGraph Clean Power, offers a new path. It does not only reduce REE reliance, it improves products, lowers emissions, and strengthens industrial resilience.

HydroGraph’s Inputs and Process

Unlike traditional graphene suppliers that rely on energy intensive chemical vapor deposition (CVD) or unreliable exfoliation methods, HydroGraph uses a patented chamber combustion synthesis process:

• Inputs: simple, abundant gases acetylene and oxygen.
• Process: The chamber combustion synthesis process is simple, low energy, low cost, modular, and scalable, producing consistent graphene.
• Outputs: two valuable streams:

1. Graphene: 99.8 percent pure few layer, fractal graphene for use an a seemingly endless amount of applications.
2. Hydrogen rich syngas: captured as a by-product for use in energy, chemicals, or as a feedstock in hydrogen markets.

This dual output model means governments subsidizing HydroGraph are not only investing in graphene, they are also enabling domestic hydrogen capacity.

What Sets HydroGraph’s Graphene Apart

Most “graphene” on the market is mislabeled graphite dust, HydroGraph is making real graphene and their product stands apart:

• Patented process for making 99.8 percent pure, 100 percent sp² bonding, 100 percent crystalline, turbostratic, few layer, fractal graphene.
• Verified purity and consistency: Verified by the Graphene Council and ISO 9001 certified, gives industrial buyers confidence. (although more industry standards are needed)
• Scalable modular units of twenty five tonnes per year can be deployed rapidly, with low cap-ex in acetylene facilities across NATO countries to satisfy orders swiftly and efficiently.
• Low cost structure since chamber combustion synthesis uses minimal energy, making it’s costs competitive with REE substitutes.
• Hydrogen capture means each production cycle yields hydrogen, creating a two for one subsidy payoff. This hydrogen byproduct can be collected and sold, or used to power the production facility.

Key REE Overview

• Neodymium (Nd), Praseodymium (Pr), Dysprosium (Dy), Terbium (Tb): critical for high strength permanent magnets, the largest and most valuable REE market.
• Yttrium (Y), Europium (Eu), Terbium (Tb): used in phosphors for displays and LEDs.
• Cerium (Ce), Lanthanum (La): used in polishing powders, catalysts, and alloys.
• Scandium (Sc): prized in aerospace alloys for lightweight strength.

There are 17 rare earth elements in total, but only a handful drive most industrial demand and nearly all strategic supply concerns. Demand looks very different depending on the lens. By value, permanent magnets account for roughly 90 percent of market importance because they use the highest value elements (Nd, Pr, Dy, Tb). By volume, magnets are closer to 29 percent of tonnage, while cheaper oxides such as cerium and lanthanum dominate catalysts, polishing powders, and alloys.

Where Graphene Could Enable REE Substitution

1. Electric Vehicles (EVs) and Wind Turbines (Nd, Dy, Tb, Pr)

• Today: most EVs use NdFeB permanent magnets, around 1.5 kilograms per vehicle, about 7.5 grams per kilowatt.
• Large wind turbines can require 200 to 600 kilograms of NdFeB magnets per megawatt of capacity, depending on design. Offshore turbines in particular often use direct-drive systems that are magnet intensive.
• Potential: Magnet free motor designs are already being trialed by companies such as BMW and Tesla.
• In wind, alternative drivetrains such as superconducting or advanced induction generators are being researched. Graphene enhanced copper windings and thermal films could improve both EV and wind systems by reducing heat losses and improving conductivity.
• The Numbers: by 2035, up to thirty percent of EVs could be REE free (IDTechEx). Even with slightly lower torque density, REE free motors reduce material costs by twenty to forty percent (MDPI). Graphene enhanced copper wires have demonstrated around one percent efficiency gains at a lower cost than REE magnets (PNNL and DOE).
• Government gain: lower REE import reliance, stronger EV competitiveness, and emissions reductions.

2. Consumer Electronics (Nd, Pr, Dy)

• Today: billions of phones, earbuds, and appliances use NdFeB micro magnets.
• Potential: graphene diaphragms and thermoacoustic speakers could eliminate magnets in some devices.
• Government gain: mass scale demand reduction in consumer goods.

3. LEDs and Displays (Ce, Y, Eu, Tb)

• Today: REE phosphors such as Ce:YAG, Eu, and Tb dominate lighting.
• Potential: graphene quantum dots have demonstrated REE free phosphors in laboratory LEDs.
• Government gain: cleaner lighting supply chains, reduced toxic mining.

4. Semiconductors and Polishing (Ce)

• Today: cerium oxide dominates chemical mechanical planarization (CMP) slurries.
• Potential: graphene oxide CMP slurries achieve equal or better finish in early studies.
• Government gain: cleaner fabs, less waste, reduced cerium demand.

5. Radio Frequency (RF) and Defense Electronics (Y in YIG ferrites)

• Today: Yttrium Iron Garnet (YIG) ferrites underpin radar and telecom isolators.
• Potential: graphene based nonreciprocal devices are being explored as magnet free replacements.
• Government gain: strengthened defense supply chains.

6. Catalysis (Ce, La)

• Potential: graphene supported catalysts show higher efficiency than REE oxides in trials.
• Government gain: cleaner industrial processes and reduced REE dependency.

7. Alloys and Lubricants (La, Ce, Y)

• Potential: graphene reinforcement substitutes REE alloying agents and lubricants, extending component life.
• Government gain: lighter, stronger aerospace and transport materials.

Barriers to Adoption and Policy Solutions

1. Technical Bottlenecks

• Magnetics gap: REEs still dominate in permanent magnets, as graphene magnetics are pre commercial.
• Consistency: most graphene on the market is defective, HydroGraph is rare in producing true, consistent graphene.
• Integration: new motor, semiconductor, and LED designs are needed. ➡ Solution: fund applied R&D and independent certification frameworks (ISO and ASTM).

2. Possible Economic Bottlenecks

• Cost advantage? REE magnets are assumed to be cheap, however it is estimated that a single EV costs ~$100-130 per REE magnet and ~$45-100 per magnet free EV with a copper graphene winding. This switch would actually lower the cost of the EV’s.
• Scaling: “HydroGraph’s twenty five tonne modules are small compared to global demand”. Actually, in reality these Hyperion units take up a small footprint and are incredibly scalable, meaning demand can be supplied by building as many machines as required to fill orders.
• Risk: industry will not redesign without secure supply. ➡ Solution: targeted subsidies and procurement guarantees for verified suppliers like HydroGraph, so that companies can scale and prove that they are ready to take on large contracts.

3. Institutional Bottlenecks

• Certification lag: Without recognized standards, companies hesitate to integrate graphene into critical products. Governments can de-risk adoption by creating graphene material standards and fast-tracking certification frameworks through ISO and ASTM, providing industry with the confidence to scale.
• Policy inertia: governments continue to subsidize mining instead of alternative products with substitution potential.
• Risk aversion: mission critical sectors need long testing timelines. ➡ Solution: redirect part of “critical minerals” subsidies into “critical materials substitution.”

4. The Hydrogen Advantage

• HydroGraph’s chamber combustion synthesis produces graphene, and a byproduct of hydrogen rich syngas. ➡ Solution: recognize HydroGraph as dual impact, both rare earth substitution with graphene and hydrogen generation.

Policy Benefits

• Supply chain security: displacing thirty percent of EV REE demand by 2035 equals hundreds of thousands of tonnes avoided.
• Climate gains: every tonne of REEs displaced cuts embodied CO₂ from mining and refining.
• Economic competitiveness: REE free motors reduce twenty to forty percent in material costs, graphene improves efficiency further.
• Defense readiness: reduced exposure to adversarial REE export controls.
• Job creation: a domestic graphene industry builds high tech jobs and exports.
• Hydrogen market: graphene production adds hydrogen capacity, dovetailing with national strategies.

What’s Emerging vs What’s Proven

Proven and commercializing:

• Graphene Cu conductors (PNNL and DOE).
• Graphene oxide CMP slurries (lab to pilot scale).

Emerging and research stage:

• Graphene quantum dots for LEDs.
• Graphene nanoribbon magnets (Kyoto University).
• Graphene RF nonreciprocal devices.

Next Steps

Governments have a unique chance to replace dependence with resilience, dirty supply chains with clean materials, and import reliance with domestic innovation.

Subsidizing graphene is not a cost, it is an investment in national security, industrial leadership, emissions reduction, and the hydrogen economy. It is crucial that governments act now to fund the R&D for various applications of this “wonder material” so we are not so dependant on REEs moving forward.

Governments that act today will lead not only the clean energy transition, they will lead the next industrial revolution.

Those that wait will remain dependent.
