Voltagen Innovator Newtrace Raises $6.3M to Cut Green Hydrogen Costs

Newtrace, a deeptech startup developing high-performance electrode and electrolyzer technology for green hydrogen production, has raised ₹56.93 crore ($6.3 million) in its Pre-Series A round, led by HDFC Bank Limited and MITSUI SUMITOMO INSURANCE Venture Capital, with participation from Peak XV’s Surge, Aavishkaar Capital, Speciale Invest, Micelio Technology Fund, and angel investors Manish Prataprai Gandhi and Renu Manish Gandhi.

Green hydrogen is emerging as a critical pillar of global decarbonization and is the only scalable clean fuel capable of replacing fossil fuels across sectors such as steel, refining, fertilizers, chemicals, and heavy transport. The global green hydrogen market is projected to reach $38.1 billion by 2029 and expand to $1.4 trillion annually by 2050. Yet today, less than 1 percent of the world’s hydrogen is green, with high costs remaining the biggest barrier.

Green hydrogen currently costs $4 to $10 per kilogram, more than double the cost of conventional grey hydrogen. A significant portion of this cost and inefficiency originates in the electrolyzer stack, particularly the electrode, where most performance losses occur.

At the same time, India’s National Green Hydrogen Mission has set a target of producing 5 million metric tonnes of green hydrogen annually by 2030, supported by ₹19,744 crore in government incentives. However, India currently lacks a domestic supply of high-performance electrolyzer electrodes, creating both a strategic vulnerability and a major opportunity for indigenous innovation.

Founded in 2021 and headquartered in Bengaluru, Newtrace has developed Voltagen, a proprietary advanced electrode technology designed for alkaline water electrolyzers. Voltagen improves energy efficiency, extends system lifetime, and reduces overall hydrogen production costs. Designed as a drop-in replacement for existing electrodes, Voltagen enables electrolyzer manufacturers and hydrogen producers to upgrade performance without redesigning their systems. Newtrace has also commercialized membraneless electrolyzer technology as part of its broader platform.

Newtrace primarily serves electrolyzer OEMs, green hydrogen project developers, and industrial gas companies. Its technology is positioned to support India’s rapidly expanding electrolyzer manufacturing ecosystem, as well as global customers seeking higher efficiency and more reliable supply chains.

Voltagen is built on three core technology pillars: a high-performance catalytic architecture engineered at the micro and nanoscale to improve efficiency, a durable coating system that ensures long operating life under industrial conditions, and a scalable manufacturing process designed for commercial production. These innovations reduce energy consumption per kilogram of hydrogen produced, extend electrode life, and create a domestically available alternative to imported components.

Newtrace was founded by Prasanta Sarkar and Rochan Sinha, who bring deep expertise in electrochemistry, materials science, and industrial scale-up. The company operates from a 30,000 square foot technology center in Bengaluru and is supported by a multidisciplinary team of more than 45 engineers and scientists. It holds multiple patent applications and has received recognition under India’s National Green Hydrogen Mission. The company has also presented its technology to global audiences, including a showcase before Narendra Modi during National Startup Day 2026.

“Green hydrogen’s cost problem is fundamentally a materials and manufacturing challenge,” said Prasanta Sarkar, CEO and Co-Founder of Newtrace. “Voltagen represents a new materials foundation that enables the efficiency and durability required to make green hydrogen cost competitive. This funding allows us to transition from proving the science to scaling manufacturing.”

“We built Newtrace to address the most critical and underinvested component of the electrolyzer stack,” said Rochan Sinha, CTO and Co-Founder of Newtrace. “Our focus now is on translating our technology into reliable, scalable manufacturing that can serve the global hydrogen economy.”

The newly raised capital will support pilot-scale manufacturing, customer validation and supply agreements, and expansion of manufacturing and engineering capabilities. Newtrace expects to begin initial commercial deliveries of Voltagen electrodes within the next 12 months.
