In a statement on Friday, Eden said it would buy all the shares in Chicago-based HyRadix in return for 1 million of its own securities.

Eden said HyRadix systems have already been installed in California, China and Malaysia for use in transport, oil hydrogenation and metal annealing.

The company said the US systems were a “natural fit” with its own suite of hydrogen fuel technologies – in particular allowing for onsite production and dispensing of Hythane, its own patented hydrogen-natural gas blend.

“A combined Eden-HyRadiz product provides an immediate opportunity to not only continue to supply a fully developed, complete Hythane system able to now be marketed to India, the United States, China and Europe,” Eden executive chairman Greg Solomon said.

“It rapidly expands the market potential for an ultra-low emission, high efficiency blend of hydrogen and natural gas that can be the ideal transitional fuel.”

Several months ago, the company signed a deal with Gujarat State Petroleum Corporation (GSPC) – one of India’s largest energy groups – to market Hythane through the state of Gujarat.

In addition, it has secured a 10-year agreement with India’s large bus and heavy transport group, Ashok Leyland, to introduce Hythane across tens of thousands of public transport vehicles in India.
