Ensys and KEPCO Partner to Turn Hydrogen Byproducts into Battery Materials

Ensys has signed a joint R&D agreement with KEPCO and two Korean power generators to develop turquoise hydrogen production and convert the solid carbon byproducts into battery materials. The consortium aims to produce 700 kilograms of turquoise hydrogen per day by 2031, generating roughly 765 metric tons of solid carbon annually. Ensys plans to refine that carbon for use as conductive additives in LFP battery electrodes and as carbon coating materials for current collectors, with potential expansion into all-solid-state battery anodes. The project runs through May 2030 with a 6.3 billion won budget. KEPCO has been working on turquoise hydrogen since 2017 and built a pilot system in 2024. The partners claim the process can cut production costs by over 30% by using existing natural gas infrastructure. For anyone tracking low-carbon hydrogen or battery material supply chains, this is a concrete example of turning a process byproduct into a usable input rather than treating it as waste.

Interesting to see a battery equipment company pivot into hydrogen byproduct valorization. The 700 kg/day target is modest but the carbon reuse angle for LFP electrodes is what makes this worth watching.

Yeah the carbon black replacement angle is the part that actually has a clear market. Conductive additives for LFP are a known volume. The question is whether the turquoise hydrogen economics pencil out at that scale.

700 kg/day is tiny for hydrogen. That is roughly 255 metric tons per year. For context a single large SMR can do 100,000 tons. This is pilot scale. The carbon byproduct volume is also small. The real test is whether they can scale the catalyst and reactor design without fouling.

The 30% cost reduction claim compared to green hydrogen is worth questioning. That depends heavily on natural gas prices and carbon pricing. Turquoise hydrogen still emits CO2 if the solid carbon is later burned or oxidized. The lifecycle accounting matters.

If the carbon ends up locked in battery electrodes that is a decent end use. But 765 tons of solid carbon per year is a rounding error for the battery industry. This is more about proving the concept than moving the needle on emissions.
