DCARB are an impact based company with sustainability at our core.  

Our purpose is to help decarbonize our planet – NOW.   

We achieve this through creating strongly aligned, long term partnerships with our clients and completely decarbonising their diesel engine fleets over the coming years through ground-breaking hydrogen solutions. 

 Available today is our D100 technology at ZERO up front cost on a no risk, no lock in period subscription basis, which will yield immediate carbon and cost savings of up to 15%.



In most instances across all sectors our clients are cashflow positive from day one. For larger engines we supply our technology free of charge (no CAPEX), in return we receive a small share of the fuel savings.


Our ethos is based on building long term mutually beneficial partnerships, we grow together and benefit through our evolving technology, creating greater financial reward and greater sustainability achievements. We have developed immediately deployable, highly effective, scalable, hydrogen solutions to help you reduce your diesel emissions, reduce your fuel consumption, reduce your carbon footprint and improve global sustainability – right now. Our business model has been designed so you will constantly benefit from our evolving technology. Therefore, we don’t “sell” anything because we innovate too quickly, we need to optimize your ability to constantly be ahead of the curve.  

We have to be incredibly tech fluid.

Our business model is a no risk subscription program, this means you don’t need to commit Capex to access our evolving technology applications, which we rapidly and continuously update. At DCARB we work with you to achieve both your short term and long term sustainability targets and make sure you always have the advantage. We are able to achieve this for you through, not just our evolving technologies, but our innovative business model. Our impact investors understand powerful emerging technologies and support big investment in resourcing our no Capex model allowing immediate consumer uptake with no consumer risk.  

“We believe all great partnerships are built on great communication.”

Let’s start a conversation today!


Our DCARB Fleet Program uses our D100, a smart device that enhances vehicle efficiency. It’s attached to vehicles, powered by their batteries, and generates hydrogen from tap water on demand. A flat monthly subscription fee per unit, which will be less than your fuel savings.
No upfront capex or fitting fee. If you are unhappy with the service at any time, you return the unit to stop the subscription at any time, for any reason, at no cost. 

The DCARB Fleet Program billing cycle begins 30 days from when your program starts. Within a day following your first DCARB installation, you will start to realise the on average 5% fuel savings. If your fleet asset consumes more than $1,800 per month of diesel, the 5% fuel savings will more than cover the monthly fees. Not to mention all the additional benefits such as less downtime and maintenance costs.  

By adding a small amount of hydrogen during the combustion process the fuel is more completely burned. In addition, the hydrogen bonds with the carbon that has built-up in the engine frame, this forms a low energy hydrocarbon that leaves the engine as CO2 gas – removing these deposits.

This process leads to a cleaner engine that restores power, performance, and efficiency to like new. On average, we see between a 5 – 15% reduction in diesel consumption, fewer ongoing maintenance issues, longer oil service ( from 8% soot to 1%), and less wear and tear, leading to a longer engine service life.

With our patented software technology, we constantly monitor the performance parameters of your assets and this enables us to remotely optimise the hydrogen generation and injection characteristics on every individual engine. This ensures we are generating the greatest possible advantage for you… 24 hours a day, 7 days a week, 365 days a year…

Not at all, we have never had any issued during the past 6 years and in the highly unlikley event it does cause any damage to your engine, we are fully insured.

We allow up to two hours to complete the installation of the DCARB 100 at your location.  You will notice the difference within hours of driving.

Our DCARB 100 won’t impact your existing warranties. Even while your asset remains under warranty, you can experience the immediate benefits of the DCARB 100, including lower fuel costs, reduced regen, and decreased maintenance expenses.
