MOx Energy – Reusable Zero Emission Fuel
Currently we are seeing a once in a lifetime change with energy use rapidly shifting to renewable sources. With unprecedented social and financial drive, MOx Energy metal fuel systems are now a viable option for future energy solutions.
MOx Energy
FOSSIL FUEL REPLACEMENT
MOx is a carbon free fuel replacement providing similar energy density and burning temperatures but with no emissions
REAL ZERO EMISSIONS
The MOx Energy fuel burns with zero emissions (no CO2, no NOx) and is fully recyclable. MOx is clean heat.
FIXES HYDROGEN STORAGE PROBLEMS
The MOx Fuel is safe to store and transport with current technology. MOx is an energy carrier to complement the hydrogen economy.
LONG DURATION ENERGY STORAGE
MOx is a clean, safe, easy option for storing and transporting energy. It complements the green hydrogen economy.
RENEWABLE ENERGY EXPORT
MOx is a high density, zero emission, energy carrier. This is a key enabler for the export of renewable energy.
MOx IS NEW TO THE MARKET
The market, technology and environmental developments are enabling MOx Energy as the only true zero emission renewable.
Key Markets
The current zero emission mantra of “Electrify Everything” doesn’t work economically or practically in two key energy markets: •Long duration energy storage. •High temperature process heat.
MOx solves these problems.
Hydrogen is not easily stored or transported at utility scale, MOx fuel is.
CLEAN INDUSTRIAL HEAT
MOx Energy can provide a simple low cost solution for clean industrial heat. The current zero emission energy solutions are not suited to high temperature industrial processes greater than 750C.
This is heat used in furnaces, reactors, and ovens. Traditionally these are heated with hydrocarbon-based fuels. Electricity is good for processes up to 650C.
MOx does not create nitrous oxides (NOx) when combusting. It is true zero emission.
Industrial process heat accounts for 25-30% of energy use globally. In Australia, it is an $8 billion per year market.
LONG DURATION ENERGY STORAGE (LDES) & ENERGY EXPORT
MOx energy can easily, safely and economically store energy for long periods, and readily be used, or exported, where there is a requirement for 10 to 100+ hours of energy storage. Solar and wind work well for 330 days of the year, but weather is unpredictable, and storms, clouds, calm days cause power generation reliability problems.
Batteries cannot be used for this, hydrogen storage is not proven at utility scale (many problems).
MOx fuel (metal powders) are already commercially stored and transported. MOx fuel can be easily exported using current shipping infrastructure.
Key Advantages
No Waste, Zero Emissions
- The MOx cycle is fully recyclable, repeatable, and has no harmful emissions. Everything is recycled.
Fully Scalable
- Combustion of fuels is well understood, and completely scalable
Continuous, Dispatchable Power
- Unlike other renewable energy sources, which deliver variable power, MOx Energy is fully dispatchable providing high-intensity on-demand power
Real Seasonal Storage Solution
- MOx fuel can be safely stored long term (days – years) and can provide on demand energy at high discharge rates.
Very High Energy Density
- MOx fuels have energy densities that are better than hydrocarbon fuels, and significantly exceed those of either batteries or hydrogen storage systems.
Low Capex/Retrofit Solution
- The MOx Energy systems are a low capex, self contained unit, or easily retrofitted into current natural gas systems.
MOx is a Fuel that Burns
MOx Energy burns metal fuels instead of fossil fuels to create heat. The energy content and temperatures are very similar to diesel fuel. It is cost-comparable with hydrogen, and once the fuel is burnt, the ash is collected and can be completely recycled back to usable fuel. When the energy used for recycling the fuel is sourced from renewable, zero emission sources, then the whole energy cycle is zero emission, fully sustainable, and fully renewable.
The MOx fuel is a powder that once fluidised in an air stream can be fed to a burner, combusting at the same temperatures as fossil fuels. When the fuel burns the metal is oxidised, which releases the heat. For example, burning iron creates iron oxide: 2Fe + 1.5O2 –> Fe2O3. This is the same process as we know when iron rusts, but in a flame it happens much faster, and with an intense release of energy. MOx burns at high temperatures, equivalent to burning coal, natural gas, diesel or other fossil fuels. The heat generated is suitable for industrial processes. The key difference is there are no CO2 or methane emissions.
The waste ash is collected, and converted back to the original metal using green hydrogen or electrolysis. The MOx fuel can be stored safely and almost indefinitely. It can also be easily, and safely transported.
Closed Loop
The MOx energy cycle is a closed loop system. The fuel is burnt, recycled and then burnt again:
MOx fuel made from a mixture of metal powders is burnt to create heat.
- This is high-temperature heat (2,000°C-3,000°C)
- MOx fuel has a similar energy density as fossil fuels.
- The fuel burns with no carbon emissions.
The burnt, or spent, fuel is collected and is fed to a recycler.
- The recycler uses green hydrogen to convert the fuel back to its original state.
- The only emission is water vapour.
- The fuel can then be burnt again. This cycle can be repeated indefinitely.
“These opportunities include the replacement of fossil fuels in ammonia, alumina and steel manufacture, and in the cement industries.” (Arena).
