Not all hydrogen are created equal.
Carbon-positive hydrogen e.g. ‘Grey’ and ‘Blue’ type produced via SMR and SMR+ CCS respectively, emits substantial GHG.
Carbon-negative or at least carbon-neutral hydrogen, are important for reversing and stopping GHG emissions.

Carbon-Negative Hydrogen
To optimally mitigate climate change, both legacy CO2e emission removal and preventing on-going emission and are necessary. Producing carbon-negative hydrogen and a carbon black by-product using bio-methane, is our primary focus. It results in the removal of atmospheric CO2 equivalent of -1 to -10.4 tonne (configurable) locked in as carbon black.
The distinct advantage of using carbon-negative hydrogen is, it affects legacy emission removal plus prevent on-going emission, delivering optimum climate change mitigation impact.

Carbon-Neutral Hydrogen
Carbon-neutral (or electrolysis) hydrogen has its value in mitigating climate change. Where the goal is only to prevent on-going emission, and other criteria such as renewable electricity and product cost, permitting, the production and use of carbon-neutral hydrogen shall be the option. The decarbonization’s % impact from prevented CO2e emission, as compared to baseline carbon-positive (or SMR) hydrogen is shown in the comparison table:
Carbon-Negative Hydrogen Solutions
Carbon-negative e-Methanol is more than a clean fuel. When used, its carbon-negative trait reverses atmospheric GHG. It is produced using bio-CO₂ from sustainable sources and carbon-negative hydrogen (atmospheric CO2 removal) and powered by renewable electricity.
The e-Methanol’s carbon-negative intensity ranges from -9.4 to -97.5 g CO2e per MJ. In comparison, carbon-positive methanol’s CO2e emission intensity is +109.9 g CO2e per MJ, which is 127% to 213% higher.
Our e-Methnaol production capacity starts at 20,000 tonnes per year and is scalable to 60,000 tonnes per year.
Our drop-in solution for decarbonizing shipping, bio-diesel, e-fuels & chemical production, etc., offers an effective pathway for businesses to meet and exceed their GHG emission goals.

Carbon-positive (or grey) ammonia, produced using natural gas, emit a significant GHG emission debt of about 2 tonnes of CO2 per tonne of ammonia, accounting for about 2% of global CO2 emission. This high CO2 emission stems from using carbon-positive hydrogen produced from the natural gas.
Fertilizer production consumes some 55% of ammonia produced globally. Fertilizer production is a key CO2 emission debt contributor. Reliance on fertilizer in the agriculture and plantation businesses puts it in a hard to decarbonize category.
Transitioning fertilizer production to using carbon-negative hydrogen offers a feasible solution to decarbonizing agriculture & plantation businesses. That will lead to carbon-positive (or grey) urea fertilizer’s emission of +0.93 tonne CO2e per tonne urea dropping to -1.06 tonne CO2e.
Resulting in a 214% business decarbonization impact improvement compared to carbon-positive urea.
As only the hydrogen used is changed, production changes should be negligible or none.

SAF’s primary goal is to decarbonize flight emission. Currently SAF production rely on carbon-positive hydrogen from fossil fuels. Thus, falling short of SAF’s primary goal by still contributing to atmospheric CO2 emission.
Note: 1) SAF-HEFA refer to the current commonly adopted SAF production method.
2) Hydrogen carbon-negative -1 tonne CO2e and +3.32 tonne CO2e (or blue), have similar pricing.
The % emission reduction by SAF as compared to conventional Jet A fuel provides further clarity.
Clearly, SAF’s decarbonization objective is most effectively realized by switching to use carbon-negative hydrogen in SAF’s production.

Due to hydrogen’s unique chemical properties, a number of industries harness and benefit from these properties as a process gas.
Semiconductor production uses ultra-pure hydrogen for cleaning, etching, removing impurities and prevent silicon wafer oxidation, to ensure the quality of production and microchips.
Edible oil processing uses the hydrogenation process to improve the texture, stability, and shelf life quality of products like margarine, shortening, frosting and icing.
Green steel production. Hydrogen is increasingly being used as a reducing agent in steel production, instead of coke (a type of carbon) which releases significant CO₂ emissions.
Industrial combustion is currently dominated by fossil fuels like natural gas, coal, and oil. A simple retrofit to the combustion system to introduce a relatively small volume of hydrogen as a catalyst, improves thermal efficiency reducing fuel consumption. Significantly, it reduces harmful pollutants, including nitrogen oxides (NOx), carbon monoxide (CO), particulate matter and CO2 emissions.
However, carbon-positive hydrogen (grey) dominates the supplies used. Switching to use carbon-negative hydrogen impacts the decarbonization of the process and its products.
Carbon-negative hydrogen delivers a significant cost-benefit advantage of +3.9% cost increase compared to +205.2% decarbonization impact increase.
