Let’s work together

Through the use of baseload, zero-carbon geothermal power and methane with no upstream emissions, we produce a continuous stream of hydrogen with a carbon intensity (CI) near 0 kg CO2e /kg H2. In fact, under international standards--which use the displacement method--by avoiding much dirtier carbon black production processes our carbon intensity is negative.
