01 Decarbonising what can't be electrified

Turning pollution
into power.

We retrofit an electrochemical system onto your existing gas boiler that filters CO₂ from the exhaust and converts it into electricity. It works with existing infrastructure, no fuel change, and it's a solution that isn't 10 years away.

02 The reality on the ground

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

Boilers can't be switched off and electrification is near impossible. Most decarbonisation paths force you to choose between hitting your targets and staying operational. We aren't asking our customers to sacrifice profitability for sustainability. We are showing sustainability is the margin.

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

Pollution becomes the asset.

Instead of letting CO₂ escape into the atmosphere, our bolt-on electrochemical system filters the CO₂ and, through an electrochemical reaction, utilises it to produce electricity which is fed back into the building itself.

01 · FILTER

From the exhaust stream

Our system attaches to the existing boiler exhaust, meaning little to no operational changes.

02 · CONVERT

CO₂ into stored energy

An electrochemical reaction utilises the captured CO₂ into usable electricity.

03 · POWER

Back to your operation

This clean electricity is fed back into the building or facility, reducing energy costs and your Scope 1 emissions.

04 Where it works

Built for buildings that run on gas.

Commercial property groups and building owners are our primary market. With our current focus being NABERS-rated buildings that are still using gas. If this is you or someone you know, we would love to chat.

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.
