Our vertically integrated delivery solutions for zero emissions resources
Renewable power
Pathways to decarbonise our electricity infrastructure are well underway with solar, wind, hydropower and biomass. Increasingly, technology is being developed to enable low carbon hydrogen to be utilised to decarbonise the mobility and transport sectors, traditionally heavily reliant on fossil fuels.
Utilising one-sixth the renewable energy land requirements of solar farms as compared to alternative technologies enables the efficient use of our scarce resources. Providing renewable power as part of the Sub.Zero integrated offering is unique and one that provides an economic pathway for us to grow as broader hydrogen applications and technologies develop.
We are actively engaging in the utilisation of existing, and the development of new renewable power infrastructure as hydrogen production grows.
Sub.Zero manufacture
Climate positive hydrogen. The natural process of photosynthesis uses sunlight and carbon dioxide to “crack” the strong hydrogen-oxygen bond in water and produce the oxygen we breathe. The “leftovers” are stored as hydrocarbons in plants, that in the end make up most of our non-recyclable materials. There is no natural source of hydrogen, with most hydrogen molecules essential in fossil fuel, water and biomass.
Our Grade A green hydrogen is produced using those photosynthesis chemistry principles, efficiently combining low impact renewable power, regenerative landfill materials, and recycling captured carbon to provide below zero emissions hydrogen.
The landfill material, transformed to a valuable resource, is sourced locally reducing the emissions associated with transporting the hydrogen long distances. Hydrogen produced locally at integrated circular economy Resource, Energy, Chemical Hubs (REC Hubs) nearby to where it is to be used.
Our Sub.Zero resources include:
zero emissions green hydrogen,
biogenic carbon dioxide (CO2),
green methanol,
low carbon IMBYROCK,
cell glass, and
heat.
Sub.Zero distribution
Our preferred distribution carrier for green hydrogen is as green methanol. Uniquely, our climate positive hydrogen production is achieved efficiently with biogenic carbon dioxide fully captured directly as part of the production process. Green methanol is produced at our REC Hubs from synthesising and distilling the hydrogen and CO2.
As methanol, Sub.Zero hydrogen enhances its’ Grade A status when measured on where it is produced to being used, or “well to point” basis. This arises from the attributes of attaining the highest energy efficiency, together with the lowest carbon intensity and costs, as compared to alternative hydrogen carriers.
Our modular technology enables REC Hubs to be decentralised, enabling local production of our Sub.Zero resources. This distributed network of REC Hub production facilities minimising transport distances, carbon impacts and the costs of distributing to Sub.Zero stations.
Sub.Zero One-stop stations
We plan to develop a network of Sub.Zero refuelling and recharging stations to support the operation of zero emission vehicles. The Sub.Zero stations, distributed to provide green hydrogen and fast charge power, will service ZEV long haul and regional trucks, buses, light commercial vehicles and cars. Hydrogen refuelling times are short, usually less than 15 minutes.
Integral to the Hydrogen for the Long Haul strategy, initial Sub.Zero stations will be located and serviceable from producing REC Hubs. As greater numbers of REC Hubs are developed and Sub.Zero hydrogen off take agreements secured with ZEV fleet owners and operators, the frequency and number of One-stop stations is anticipated to increase towards 2030.
We will be developing a Sub.Zero App that provides the location and availability of Sub.Zero One-stop stations, capable to be used for refuelling, recharging and payment.
