We believe methane pyrolysis and the Clean Hydrogen it produces are vital to the energy transition.

At Monolith, our vision is to be the world’s leading Clean Hydrogen and clean materials company. By developing methane pyrolysis technology that can be produced on a commercial scale, Monolith is the only manufacturer in the world that can offer zero-emission, low-cost Clean Hydrogen and high-value carbon black. As you can see below, Monolith’s journey has been an exciting one.


Monolith was founded with the belief that you could build both a profitable company and create a cleaner world through technology.

In 2012, Rob Hanson and Pete Johnson founded the company with a simple mission to be environmentally transformative, technologically advanced and financially viable. This transformation would begin by using electricity to cleanly convert natural gas to carbon black – a chemical vital to many everyday products. The other product of that process was hydrogen. This stood in stark contrast to the pollution-riddled, industry-accepted practice of converting decant oil or coal tar to carbon black using a furnace burning process.


Monolith’s Seaport pilot project in Redwood City, CA is built, making it the first new carbon black plant built in the U.S. in 50 years.

In 2015, Monolith’s Seaport plant began producing carbon black and hydrogen. Over the next three years, the company ran the plant to determine product range and reliability, demonstrate yield and stockpile samples for further testing.


Monolith successfully concludes its pilot program and breaks ground on its first commercial facility – Olive Creek 1 (OC1).

In 2016, Monolith broke ground for a first-of-its-kind commercial carbon black facility in Hallam, Nebraska. The state offered abundant natural gas reserves, a central shipping location and a unique partnership with the Nebraska Public Power District (NPPD).


Monolith’s OC1 facility reaches mechanical completion and begins the commissioning phase.

In Q2 of 2020, Monolith reached mechanical completion of its commercial-scale plant OC1. The commissioning of the plant is now underway with customer deliveries of carbon black.

2021 & Beyond

Monolith expands its Olive Creek facility and begins developing additional sites to serve global demand for carbon-free hydrogen and clean carbon black.

Monolith is working to quickly scale up its operations through its Olive Creek expansion in Nebraska, while also planning rapid expansion to serve the Clean Hydrogen, carbon black and ammonia demands of clients across North America and around the world.
