01 Decarbonising what can't be electrified

Turning pollution
into power.

We retrofit an electrochemical system onto your existing gas boiler that captures CO₂ from the exhaust and converts it into electricity. No new equipment. No fuel change. No downtime.

02 The reality on the ground

You've been told to decarbonise.
You also need to keep running.

Your boilers don't switch off. Your building still has twenty years of operational life. Your gas infrastructure is mission-critical. Most decarbonisation paths force you to choose between hitting your targets and staying operational — and the cost of doing nothing keeps climbing.

Air2Energy is the third path.

~30%
of global CO₂ comes from hard-to-abate sectors that can't fully electrify with today's technology.

03 The technology

Exhaust becomes electricity.

A bolt-on electrochemical system that captures CO₂ from your gas boiler exhaust and converts it directly into electricity — stored in a battery module that feeds clean power back into your building.

01 · FILTER

From the exhaust stream

Our capture array attaches to your existing boiler exhaust. No retrofits to the combustion asset itself. No operational changes.

02 · CONVERT

CO₂ into stored energy

An electrochemical reaction converts captured CO₂ into electricity, stored in our integrated battery module — designed for commercial building duty cycles.

03 · POWER

Back to your operation

Clean electricity feeds back into your building or the local grid, offsetting energy costs and reducing your carbon footprint from day one.

04 Where it works

Built for buildings that run on gas.

Commercial property groups and building owners are our primary market. If you operate gas boilers at scale, you're our customer — and the system retrofits onto the assets you already own.

Commercial buildings

Office towers, hotels, mixed-use developments. Retrofit onto existing gas boilers without disrupting building operations.

Industrial heat

Gas boilers, furnaces, process heat. Capture CO₂ from exhaust without changing your fuel source or process.

Generators

Remote sites, mining, backup power, off-grid operations.

05 The founders

Fossil fuels aren't going away. Their emissions can.

Fossil fuels power our modern world and for most industries, that's not changing anytime soon. But the emissions that come with them are a growing problem, and the pressure to act is real. The world needs a solution for today, not one that's a decade away and requires scrapping infrastructure that still works.

We asked ourselves, why can't decarbonisation be profitable?

Air2Energy retrofits directly onto existing commercial gas boilers, capturing CO₂ from exhaust and converting it into electricity on-site. No rip-and-replace. No new fuel source. Just a system that turns waste into something a building can use. We're starting in commercial buildings, then taking the same approach into mining, marine, and long-haul transport.

Andrew has spent years obsessing over the gap between sustainability ambition and operational reality, studying Business (Finance) and Sustainability and Environment at UTS alongside a Diploma in Innovation, while running ventures across industries from aquaculture to biotech. That pattern-matching across sectors is what drove him to Air2Energy: a commercial decarbonisation problem that nobody had solved at the building level.

Kirah's Advanced Science degree and Diploma in Innovation give her the technical foundation to understand exactly why existing decarbonisation solutions fail at the electrochemical level and what it takes to build something better. Her background in complexity and sustainability systems means she thinks in feedback loops, not just components.
