How large is the Climate Tech investment landscape today?

Global energy transition investment reached about $1.77 trillion in 2023, and clean energy investment is on track to approach $2 trillion in 2024. This pool spans venture, growth equity, and infrastructure capital, increasingly directed at build‑out of large‑scale assets.

What’s driving the recent momentum in Climate Tech startups?

Policy tailwinds like the U.S. Inflation Reduction Act and the EU’s Green Deal Industrial Plan have improved project economics and accelerated siting and manufacturing. Corporate demand from buyers such as Microsoft, Amazon, and Shopify is creating bankable offtake for early markets like carbon removal and 24/7 clean power.

Which technologies are emerging as near‑term winners?

Long‑duration storage (e.g., Form Energy), industrial heat batteries (e.g., Rondo Energy), and enhanced geothermal (e.g., Fervo Energy) are moving toward multi‑site deployments. Carbon management players like Climeworks and Carbon Clean, alongside circular materials leaders such as Redwood Materials, are also scaling rapidly.

What are the biggest hurdles to scaling Climate Tech?

First‑of‑a‑kind projects face capital intensity, permitting complexity, and supply‑chain risks. Bankable customer contracts, partnerships with incumbents like Schneider Electric and Shell, and policy certainty help convert one‑off pilots into repeatable, financeable asset classes.

What is the outlook for Climate Tech exits and growth through 2030?

Public markets remain selective, but strategic M&A and growth equity are active as projects de‑risk and cash flows stabilize. With continued policy support and corporate procurement, leaders such as Northvolt and Climeworks are positioned to expand from initial facilities to gigascale deployments by decade’s end.

Climate Tech Market Trends: Startup Ecosystem Accelerates in 2024–2025

Climate tech is shifting from experimentation to large-scale deployment as capital, policy, and corporate demand converge. Despite a choppy venture market, the sector’s share of investment is rising and a new cohort of scale-ups is moving from pilots to gigafactories and commercial offtakes.

Momentum Builds: Funding Stabilizes as Deployment Surges

Global energy transition financing set a new record at $1.77 trillion in 2023, according to BloombergNEF’s latest analysis. Clean energy investment is poised to reach roughly $2 trillion in 2024 as it outpaces fossil fuels by nearly two-to-one, IEA data shows. That capital is increasingly reaching infrastructure-scale projects that underpin climate startups’ growth trajectories, from battery plants to carbon removal hubs.

Venture activity has cooled from 2021 highs, but climate tech continues to outperform broader VC as a share of deal flow, according to PwC’s State of Climate Tech 2023. The shift in focus—from rapid seed rounds to growth equity and project finance—reflects a maturing pipeline. Startups such as Climeworks in carbon removal and Fervo Energy in next‑gen geothermal are now executing multi-year buildouts anchored by long-term customer contracts.

The breadth of climate solutions is widening across hardware, software, and services. Companies such as Northvolt (batteries) and H2 Green Steel (low‑carbon steel) embody the industrial scale of the opportunity, while buyers like Microsoft and Amazon are catalyzing demand via clean power PPAs and carbon removal procurement that de‑risk early markets.

Capital, Policy, and the New Geography of Scale

A new financing stack is taking hold as venture blends with infrastructure capital. Early backers including Breakthrough Energy Ventures and Lowercarbon Capital are increasingly pairing with project lenders to fund first‑of‑a‑kind assets. Startups such as Fervo Energy and H2 Green Steel exemplify this progression from lab to commercial scale, supported by policy incentives and corporate offtakes.

In the U.S., the Inflation Reduction Act has catalyzed a manufacturing and deployment surge across batteries, hydrogen, and grid tech—spurring hundreds of billions in announced projects, the White House reports...
