Our Technology

HERC* revolutionizes industrial heating with breakthrough PAC solution expanding thermochemical combustion boundaries.


HERC* Tech is a patented method for generating low-temperature plasma by converting waste heat from redox reactions (and/or other heat sources) into a flux of ionizing radiation.


The technology is embodied as a family of self-powered vacuum nanoelectronic units in a form factor from chip to ceramic tiles.


HERC* utilizes plasma-assisted combustion (PAC) to dramatically increase combustion efficiency.


The self-powered, easy-to-install HERC* chip and nano-ceramic forms are designed for use in existing and new industrial heat systems.

Unbeatable Benefits

Delivering unbeatable benefits to the industrial heating sector.

Retrofittable Design

HERC* can be easily installed into existing infrastructure, without the need for rebuilding or upgrading. It can be installed in less than 1 hour, with simple plug-and-play capabilities.


HERC* operates without any external power source, making it a cost-effective solution. It is self powered by gaining energy from the waste heat of the combustion.

Durable & Reliable

With no moving parts, HERC* is robust and compact, ensuring long-term reliability with minimal maintenance. HERC* is a game-changer for industrial heating processes, combining efficiency, affordability, and sustainability in a single solution.


The semi-empirical model based on the Jahn-Teller effect provides additional enthalpy in the  thermochemical combustion, resulting in a potential increase in efficiency of up to 40% for natural gas and 75% for hydrogen.

Financials & Funding Rounds

We are excited to invite investors to join us on this journey to transform the industrial energy industry with sustainable and innovative solutions.

Future Of Energy

We believe that the future of industrial energy efficiency lies in innovative solutions that offer cost-effective, energy-saving, and sustainable alternatives to traditional fuels.

Exciting Growth

While natural gas is widely used as fuel in the HTPH industry, the market for hydrogen industrial heating is in its infancy. This presents an exciting growth potential for our company as we aim to offer sustainable and innovative solutions that meet the evolving needs of this industry.

Market Boost

Based on data from the natural gas industry market, we estimate that the global combustion controls, equipment, and systems market were worth €118.4 billion in 2020. This market is expected to reach
€172.6 billion by 2028
with a 4.84% CAGR in 2021-2028. The combustion control systems segment alone is expected to be worth €20.7 billion (12%) in 2028.

Profit Increase

We are confident in our ability to capture a significant portion of this market by offering cost-effective and energy-saving solutions that cater to the needs of HTPH industrial buyers. These buyers focus on operational cost savings, low maintenance costs, long product lifespan, and GHG emission reduction, all of which our solutions offer.

With a proven track record of success and strong financials, we have secured funding rounds that have enabled us to expand our operations, research, and development, and continue to innovate.
