Green methanol
Versatile uses - H2X
Methanol applications are already very widespread due to its preferable hydrogen and use properties. Methanol is a clear liquid chemical used in thousands of everyday products, including plastics, paints, cosmetics, and pharmaceuticals. Methanol is also an energy resource used in the marine, automotive, and electricity sectors and an emerging renewable energy resource.
Methanol can be transported and stored easily and safely, being a liquid at room temperature. It is water-soluble, biodegradable and a highly efficient energy carrier, burning cleanly and producing no toxins or particulates. Increasingly, methanol’s environmental and economic advantages make it an attractive alternative fuel for powering ships, engines, turbines, fuel cells and heavy-duty machinery. Ideal wherever electricity grids and batteries are either unavailable or impractical.
Carbon capture and regeneration
Capturing carbon dioxide (CO2) emissions, combining them with hydrogen from non-recyclable waste provides an accelerated path toward a Circular Economy. The methanol produced is an efficient carrier of hydrogen to provide an ultra low carbon intensive hydrogen and renewable energy refuelling source,
Sub.Zero green methanol is produced from renewable sources and is not derived from recyclable or new fossil fuels. Between 70% and 80% of ZEROS methanol is processed from renewable energy and the regeneration of organic materials, resulting in a majority green methanol resource.
Sub.Zero green methanol production uses similar principles to direct air carbon capture that captures and uses carbon dioxide in the air to produce green methanol.
High energy density
Methanol, with characteristics similar to petrol/diesel, is substantially more energy dense at 140kg H2-eq / m3 when compared with compressed hydrogen at 350 bar at 26 kg H2-eq / m3, 5.4 times greater energy density.
This results in the transfer of one tonne of compressed hydrogen at 300 bar at -30°C and -50°C taking 10.8 hours to charge and discharge. Also when taking into consideration that mobile compressed hydrogen tanks take the form of a manifolded pipe clusters, it is estimated that up to 21 times more Class 8 vehicle movements and transfers are required as compared to methanol.
Methanol has the highest efficiency and hydrogen to carbon ratio of liquid fuels combined with the lowest CO2e and $/MJ impacts. WithSimilar storage, transport and general handling convenience as compared to diesel and petrol results in lower costs, greater safety, lower truck movements and the ability to utilise existing fuel infrastructure as compared to compressed hydrogen.
Methanol to hydrogen
All CO2 produced by the HPAG process is captured. ZEROS methanol is carbon neutral, with the hydrogen and CO2 combined to produce green methanol in order to efficiently transport the hydrogen to ZEROS hydrogen dispensing stations.
By combining methanol with water, the hydrogen yield is increased by 50%. 33% of the hydrogen product delivered comes directly from water.
There is no need for specialised high-pressure storage tanks – producing just the right amount of hydrogen at the time of need or fed through buffer tanks directly into a fuel cell.
This eliminates the logistical challenges and costs inherent in distributing compressed hydrogen – with no NOx, SOx or PM emissions.
