EU Innovation Fund 2026: What the Court of Auditors Audit Means for European Deep Tech - €40 Billion Cleantech Fund Has Paid Out Less Than 1%

Published March 19, 2026 | Startuprad.io

The European Court of Auditors published Special Report 11/2026 today — a full audit of the EU Innovation Fund, one of the world's largest public programs to accelerate commercial-scale decarbonization technology. The headline finding is stark: after nearly five years of operation, less than 1% of the fund's estimated €40 billion budget has actually reached projects.

For anyone building or financing deep tech in Europe, this is not an abstract policy story. The Innovation Fund is the primary EU instrument for bridging the "valley of death" — the critical gap between laboratory demonstration and commercial viability that makes or breaks capital-intensive climate technology companies. If that bridge is underperforming, the consequences flow downstream into startup ecosystems across the DACH region and beyond.

Here is what the report actually says, what it means, and what comes next.

What the EU Innovation Fund Was Built to Do

The Innovation Fund was established in 2020 as the successor to the NER300 programme. It is financed through the sale of EU Emissions Trading System (ETS) certificates — effectively, the proceeds of carbon pricing flow into grants for the next generation of low-carbon technology. The Commission estimates total revenues of around €40 billion between 2020 and 2030, based on the sale of 530 million ETS certificates.

The fund targets five sectors: energy-intensive industries, renewable energy, energy storage, carbon capture/utilisation/storage, and zero-emission mobility and buildings. Grants cover up to 60% of a project's relevant costs, structured around milestone payments tied to project completion stages.

The strategic logic is sound. Large-scale industrial demonstration projects — the kind needed to prove that green hydrogen electrolysis, industrial CO₂ capture, or next-generation battery manufacturing actually work at commercial scale — are too risky and too capital-intensive for private markets alone at the pre-commercial stage. The Innovation Fund was designed to de-risk exactly that gap.

What the Auditors Found

The Court reviewed the fund's operation from 2020 through June 2025. The numbers are sobering.

Of the €40 billion expected budget, roughly €18.7 billion had been raised through ETS auction revenues by June 2025 — already exceeding the original 2015 estimate of €10 billion for the entire decade, thanks to higher-than-expected carbon prices. But of that, €6.7 billion was transferred to REPowerEU via the Recovery and Resilience Facility, leaving €12 billion available for the fund itself.

Of that €12 billion, €11.6 billion is committed across 208 active grant agreements.

Actual payments to projects: €331.8 million — 2.7% of committed funds, and less than 1% of the fund's total expected capitalisation.

The project portfolio tells a similar story. Of 228 projects originally selected, 40 — roughly one in five — have been cancelled, either before grant agreement signature or afterward. Among the 208 projects with signed agreements, 20 have been terminated. Delays are pervasive: 56 active projects have already exceeded the deadlines set in their grant agreements, with an average delay of around 15 months on the way to the "financial close" milestone that triggers the first payment tranche.

The auditors visited seven projects across Denmark, Germany, Spain, France, and Italy — the only five with operational results to report by mid-2025, plus two large projects approaching commissioning. Six of the seven had delivered the intended technology. But six of the seven had also delivered fewer emission reductions than expected. The average project reached 57% of its target reduction. The portfolio as a whole achieved less than 5% of the emission reductions the Commission had projected for December 2024.

Three Structural Problems the Report Identifies

1. Funding Uncertainty Creates Paralysis

The fund's revenues depend on the ETS carbon price, which fluctuated between €23 and €97 per tonne between 2020 and 2025. There is no guaranteed minimum. The Commission must confirm available funds before setting budgets for each call for proposals — a constraint that, combined with the long-duration nature of individual projects (some spanning 15+ years of payment schedules), has led to significant accumulation of assets that are committed but not deployed.

Until 2023, the Commission did not allow call budgets to exceed actual auction revenues. Since 2023 it has begun planning against projected revenues, assuming a 10% project cancellation rate — a sensible adjustment that has allowed larger call budgets. But as of June 2025, €12.3 billion remains committed or unallocated but not yet paid out, while actual project payments stand at €332 million.

The auditors compare this to the Climate Social Fund, where the ETS Directive guarantees a minimum funding level, giving fund managers more certainty. No equivalent mechanism exists for the Innovation Fund.

2. Allocation Without Strategic Compass

Until 2022, the Commission ran its calls for proposals on a technology-neutral, sector-agnostic basis. Since the introduction of REPowerEU in 2022, it has increasingly directed Innovation Fund budgets toward specific political priorities: the European Hydrogen Bank, the Net Zero Industry Act manufacturing targets, EU battery policy.

The auditors found no evidence of a structured, forward-looking analysis underpinning these allocation decisions — no assessment of which technology pathways offer the greatest marginal emission reduction potential, nor of how Innovation Fund support interacts with or duplicates other financing available to applicants.

The practical consequences show up in proposal quality. The 2024 call for battery cell manufacturing attracted only 14 proposals. Of the six that met minimum scoring thresholds, all six were selected — leaving 15% of the allocated €1 billion unspent. No grant agreements had been signed as of June 2025. The renewable hydrogen calls similarly saw declining industry interest, from 132 proposals in 2023 to 61 in 2024.

The auditors also identified at least one case where a beneficiary cancelled a €230 million Innovation Fund grant to replace it with national funding under a member state's REPowerEU recovery plan — judging the national support more flexible and more attractive on financing rate terms. This illustrates the overlap problem in live form.

3. Project Maturity Is Systematically Overestimated

Grant agreements require projects to reach "financial close" — the moment when all financing, permits, construction contracts, and partner agreements are in place — within four years of the grant decision. Up to 40% of the grant is paid at this milestone; the remainder depends on verified emission reductions during a monitoring period of three to five years post-commissioning.

The auditors found that projects assessed as sufficiently mature at selection are routinely failing to meet these timelines. Of the seven large projects funded under the inaugural 2020 call, six required timeline amendments, with commissioning dates shifting an average of 24 months. Common drivers: higher-than-projected capital expenditure, delayed permitting, financing gaps, partner withdrawals.

The Commission has limited discretion here — the four-year financial close deadline is set in EU legislation, not administrative guidance, so it cannot extend it even where the innovation complexity arguably justifies it. Projects that miss the deadline must be terminated regardless of their progress. This rigidity contributed directly to the one-in-five cancellation rate.

A separate but related problem: the methodology for calculating expected emission reductions is theoretical and has been revised repeatedly as the Commission identified weaknesses after each call. The calculation depends on assumptions about market uptake, energy grid decarbonisation, and avoided emissions baselines that applicants have strong incentives to optimise upward.

The result, in the auditors' assessment, is structurally optimistic emission reduction projections — which distort project selection rankings and inflate the expected portfolio impact.

Three Recommendations

The Court's report includes three formal recommendations directed at the Commission, with implementation deadlines:

Recommendation 1 (by 2027): Develop a structured, forward-looking technology landscape analysis to underpin allocation decisions across decarbonisation pathways and new political priorities. This analysis should cover both mature and breakthrough technologies.

Recommendation 2 (by 2030): Explore additional measures to improve budget planning for calls for proposals and enable faster deployment of funds — with appropriate risk analysis regarding CO₂ market exposure and realistic cancellation rate assumptions.

Recommendation 3 (by 2028): Improve project evaluation methodologies to produce more accurate assessments of both emission reduction potential and project maturity; assess whether greater flexibility is needed on financial close requirements and the monitoring period for emission reduction verification.

Why This Matters Beyond the Headlines

Two things make this report more consequential than a typical EU audit finding.

First, the European Competitiveness Fund. On July 16, 2025, the Commission proposed the ECF as part of the 2028–2034 Multiannual Financial Framework, with a proposed budget of €451 billion — more than doubling EU competitiveness and research funding compared to the 2021–2027 period. The ECF is designed to complement and extend the Innovation Fund's mandate into a broader industrial competitiveness frame. The Court explicitly states that lessons from the Innovation Fund should inform the ECF's regulatory framework, implementation approach, and overall effectiveness. That design process is ongoing right now.

Second, the valley of death is still open. Despite the performance gaps identified in this audit, the fund's basic strategic logic remains valid and largely unchallenged. Businesses and industry associations consistently tell the Commission that no equivalent instrument exists at either EU or national level. Three of the seven visited projects demonstrated clear continuity from earlier EU-funded research — the fund is functioning as a bridge, just slower and with more attrition than designed. The question is not whether Europe needs this kind of instrument, but whether it can be made to work faster and with greater strategic coherence.

For DACH founders and deep tech investors, the operational implications are practical: the Innovation Fund's payment model — milestone-triggered, heavily back-loaded toward demonstrated emission reductions — means that accessing this capital requires patience, strong project governance, and the financial resilience to absorb delays. The 60% funding rate and relatively streamlined selection process (faster than the predecessor NER300 programme) remain genuine advantages. But the one-in-five cancellation rate and near-universal delays should be underwriting assumptions, not surprises.

What to Watch

The Commission is expected to respond to the audit recommendations through the formal follow-up process. Watch for: revisions to the emission reduction calculation methodology ahead of the 2025 call cycle, any legislative proposals to introduce greater flexibility on financial close timelines, and the ECF regulatory proposal — where this report will be cited in parliamentary debates.
