A new class of hydrogen
Traditionally, natural gas produces CO2 when burnt for industrial processes and for heat. The CO2 is a greenhouse gas.
To minimise global warming, CO2 emissions to the atmosphere must be materially reduced.
The Sky Blue Hydrogen process reimagines the natural gas production process. Today natural gas is processed, transported by pipeline (or by ship as LNG) and then the fossil fuel is burnt, producing CO2. Tomorrow, the produced natural gas can instead be converted to hydrogen near the wellhead, with the CO2 by-product captured and injected straight back into the gas reservoir to minimise emissions and increase the lifetime of the gas field, for it to produce more hydrogen.
The hydrogen produced can then be transported as a clean fuel with few GHG emissions.
Why is Sky Blue Hydrogen different to Blue Hydrogen?
Sky Blue Hydrogen uses a closed loop system, where natural gas is never transported away from the gas field facilities. The produced CO2 is used to increase the rate of gas production, in order to make more hydrogen. And because the natural gas never travels far, the fugitive methane emissions are minimised.
Why do we need Blue Hydrogen when we can produce Green Hydrogen?
Green Hydrogen requires large quantities of renewable electricity delivered at all times. Renewable electricity may be intermittent, with non-intermittent sources prioritised for domestic or industrial use. The addition of storage to make up for weather and time of day intermittency, adds to the cost of green hydrogen.
A hydrogen economy requires high volumes of reliable, affordable and safe hydrogen. These high volumes will likely, and most cost effectively, come from a diverse mix of the rainbow of hydrogen colours.
Sky Blue Hydrogen can complement Green Hydrogen, even working symbiotically (using AutoThermal Reforming) alongside green hydrogen production to reliably deliver clean hydrogen with minimal CO2 emissions.
