Using local renewables to power a factory, using electrolysers to split wastewater into hydrogen & oxygen to balance the micro-grid, and using the green hydrogen for backup power.
About
At Rubbish Energy, we are looking to positively affect the world by creating solutions to problems using waste products. We are developing a wastewater electrolysis system that will enable energy flexibility services, specifically islanding of communities or factories, this is sometimes referred to as a micro-grid. What this means is that the facility or community will be shielded from the effects of a larger power grid, should that grid be unreliable or none existent. We believe these services will be able to be 100% renewable.
Key Benefits
These services will be a reliable way to effectively deal with the excess renewable energy generated, allowing for balanced functioning of a micro-grid. Utilising wastewater in this process to create and store hydrogen will effectively create unlimited renewable storage. It also means that the process can continue to be effectively used, even in times of drought, as wastewater would not be subject to the drought restrictions.
As the system is able to utilise the over-abundance of renewables, the captured green hydrogen can be used as a power source to generate power when there is a lack of renewables, either through a hydrogen fuel cell, or gas turbine generators. It could be used in conjunction with methane gas to reduce the climate impact of operating the factory when there is a lack of renewables.
The islanding feature of the micro-grid will ultimately increase resilience and allow operation in areas where there is no, or poor grid infrastructure.
Applications
For Micro-grid or islanding communities or facilities.
Areas with high renewable capacity, but poor/no power grid services.
For stability of unreliable power grids for rural areas, rural communities or facilities requiring more constant and stable connections without the use of fossil fuels.
To supplement the green transition without costly power grid upgrades for out of city areas.
