Climate technology in Australia doesn’t generate the breathless coverage that artificial intelligence does. There are no viral demos, no consumer products capturing mainstream attention, and no billionaire founders dominating social media. But beneath the radar, Australian climate tech has been growing steadily and substantively, and 2026 is shaping up as a significant year for the sector.

The numbers support the observation. According to data from the Clean Energy Finance Corporation and private market tracking firm Tracxn, Australian climate tech startups raised approximately $1.2 billion in 2025 across all stages, up from $890 million in 2024. That 35 percent increase outpaced the broader venture capital market, which grew by roughly 12 percent over the same period.

More importantly, the capital is flowing into companies that are past the research stage and approaching or achieving commercial scale. This isn’t speculative investment in theoretical technologies. It’s funding for companies with real customers, real revenue, and clear paths to profitability.

Where the Growth Is Happening

Several sub-sectors are driving Australia’s climate tech momentum.

Battery technology and energy storage. Australia’s abundance of lithium and other battery minerals has spawned a cluster of companies working on battery chemistry, manufacturing, and recycling. Firms like Lavo (hydrogen storage), Energy Renaissance (lithium-ion manufacturing), and Neoen (utility-scale storage projects) are scaling operations. The federal government’s Future Made in Australia policy, which prioritises domestic battery manufacturing, has provided additional tailwinds through grants and tax incentives.

Carbon measurement and accounting. As reporting requirements tighten — mandatory climate-related financial disclosures took effect for large companies in January 2025 — demand for accurate carbon measurement tools has surged. Australian companies including Pathzero, Emitwise (now with a significant Australian office), and Ndevr Environmental have built platforms that help businesses measure, report, and manage their emissions. This is a particularly strong niche for Australian companies because local reporting requirements differ from international standards, creating a natural domestic market advantage.

Green hydrogen. Australia’s potential as a green hydrogen exporter is well documented, and several companies are moving from feasibility studies to early-stage production. Fortescue Future Industries remains the most visible player, but smaller companies like Hysata (which has developed a more efficient electrolyser) and Province Resources are making meaningful progress. Export agreements with Japan, South Korea, and Germany provide demand certainty that de-risks investment.

Circular economy and waste technology. Companies turning waste streams into valuable materials are gaining traction. Licella (which converts waste plastics and biomass into oil), Samsara Eco (enzymatic plastic recycling), and Close the Loop (recycling printer cartridges and soft plastics) represent a growing cohort of companies building commercially viable circular economy businesses.

Agricultural technology with climate applications. Given the importance of agriculture to the Australian economy and the sector’s exposure to climate impacts, companies developing climate-adaptive farming technologies have found a receptive market. Precision agriculture platforms, soil carbon measurement tools, and drought-resistant crop technologies all feature prominently in the funding data.

What’s Different About 2026

Previous years of climate tech investment in Australia were characterised by early-stage funding and government grants. The shift in 2026 is toward later-stage capital and commercial deployment.

Several climate tech companies that raised seed or Series A rounds in 2022 and 2023 are now reaching commercial milestones that attract larger follow-on investment. Hysata’s Series B round, reported at $111 million, was one of the largest climate tech raises in Australian history. Samsara Eco’s partnership with major consumer goods companies demonstrated the commercial viability of enzymatic recycling.

This maturation is significant because it addresses one of the persistent criticisms of Australian climate tech: that the country is better at research than commercialisation. The current cohort of companies is proving that commercially scaled climate technology businesses can be built and grown domestically.

The Policy Tailwind

Government policy has played a substantial role in the sector’s growth, though industry participants have mixed views on its effectiveness.

The Safeguard Mechanism reforms, which impose declining emissions baselines on Australia’s largest emitters, have created genuine demand for emissions reduction technologies and carbon offsets. This regulatory driver provides climate tech companies with a more predictable market than voluntary demand alone would generate.

The Clean Energy Finance Corporation and the Australian Renewable Energy Agency continue to provide capital and de-risking for climate technology ventures, with combined annual commitments exceeding $3 billion. The National Reconstruction Fund’s clean energy manufacturing stream, though slow to deploy, represents additional committed capital.

Critics note that policy settings remain uncertain in some areas — particularly around carbon markets and hydrogen certification standards — and that the pace of regulatory development lags the speed at which companies need to make investment decisions.

Challenges Remain

Despite the positive trajectory, Australian climate tech faces persistent challenges.

Talent scarcity affects climate tech companies as acutely as it does the broader tech sector. Engineers and scientists with relevant expertise are in high demand globally, and Australian companies compete for talent with better-funded international rivals.

Manufacturing scale-up remains difficult domestically. Australia’s manufacturing base has contracted significantly over the past two decades, and rebuilding the supply chains and workforce needed to manufacture climate technologies at scale is a multi-year undertaking.

International competition is intensifying. The US Inflation Reduction Act has redirected substantial private capital toward American climate tech companies. The EU’s Green Deal Industrial Plan has done the same for European firms. Australian companies must compete for investment and market share against heavily subsidised international competitors.

A Sector Worth Watching

Australian climate tech may lack the glamour of AI, but its economic and strategic significance is arguably greater. The sector sits at the intersection of Australia’s natural resource advantages, its regulatory trajectory, and global demand for decarbonisation technologies. The companies emerging from this intersection are building real businesses with global potential.

The next twelve months will be telling. If the current cohort of growth-stage companies continues to hit commercial milestones and attract follow-on capital, Australian climate tech could establish itself as a globally significant sector in its own right — not just a footnote to the country’s mining and energy legacy, but a defining element of its economic future.
