A2G, Mashup Ventures Make Pre-Seed Investment in Zero-Carbon Hydrogen Developer Viologen

Zero-Carbon Hydrogen Production at Grey Hydrogen Cost
"Industry’s Lowest Level of Power Consumption"
Proof-of-Concept for Single Module Completed

Viologen, a climate tech company developing zero-carbon hydrogen production technology, announced on April 28 that it has secured pre-seed investment from A2G, a Silicon Valley-based investment firm in the United States, and Mashup Ventures.


The hydrogen industry is a high-growth sector attracting large-scale domestic and international capital, supported by economic and policy initiatives. Viologen is believed to have received positive evaluations from investors by presenting a technological solution that can be immediately applied to the industry.


Viologen is developing a modular hydrogen production facility called AMPS (Advanced Modular Power System), which features a high-efficiency heating method capable of reaching temperatures above 1,000°C within minutes, and an artificial intelligence (AI)-based autonomous control system.

The company’s key competitive edge lies in reducing heating time by more than 60 times compared to existing methods and achieving the industry’s lowest level of power consumption, thus enabling the production of zero-carbon hydrogen at a cost comparable to that of "grey hydrogen." In addition, Viologen possesses technology that converts the carbon generated from fossil fuel usage into high-value chemical feedstocks such as syngas, methanol, and sustainable aviation fuel (SAF).


Viologen was co-founded by Professor Park Jungwon of the Department of Chemical and Biological Engineering at Seoul National University and Honorary Professor Kim Hyunyi of the Department of Materials Science and Engineering. The company has completed proof-of-concept (PoC) for a single module and has established a global research collaboration network with institutions such as Seoul National University, Stanford, and MIT. Following this investment, Viologen plans to accelerate commercialization by expanding its pilot-scale modular reactor and signing partnership agreements with demand-side companies.


Lee Taekkyung, CEO of Mashup Ventures, which participated in this investment, stated, "We gave high marks to Viologen for overcoming the limitations of existing technologies under the leadership of Park Jungwon, a world-renowned authority in the field of chemistry, and for its flexible applicability from small on-site installations to large-scale industrial facilities."
