EIC Pathfinder Challenges 2023: funds, focus and follow-up

On 14 March 2024 the European Innovation Council announced the results of its 2023 Pathfinder Challenges call. The Commission selected 43 projects for a combined €159 million in EU grants. The awards were made from a pool of 368 eligible proposals. The EIC frames Pathfinder as high‑risk, high‑gain research support intended to advance radical science and early technology concepts toward proof of concept.

Numbers and scope at a glance

The announcement provides a snapshot of demand and supply across two related Pathfinder tracks. The Challenge call is thematic and seeks to build coherent portfolios of complementary projects. In parallel the open, non‑thematic Pathfinder call continues to draw a far larger number of speculative and interdisciplinary proposals from the research community.

The five funded challenge areas and what they mean

The 2023 Challenge call concentrated support in five strategic areas. Each area targets early‑stage research that could open new technological paths. Below is a concise explanation of the technical and market rationale for each theme and the kinds of breakthroughs the EIC typically expects to fund.

Clean and efficient cooling

Cooling is a major energy consumer worldwide and a growing source of emissions as demand increases. Pathfinder projects in this area are expected to pursue alternatives to conventional vapour‑compression systems. Relevant approaches include solid‑state caloric materials such as magnetocaloric, electrocaloric or elastocaloric cycles, advanced heat pumps, and system‑level integration that reduces lifecycle emissions. The objective is to lower energy intensity and enable decentralised or low‑carbon cooling solutions.

Construction digitalisation

This theme covers digital design, robotic fabrication, new materials and data‑driven construction workflows. Projects may investigate computational design for material efficiency, automated on‑site manufacturing, multi‑material robotic assembly and sensorised components for performance monitoring. The underlying aim is to reduce construction waste, shorten delivery cycles and bring industrial manufacturing practices into the built environment.

Precision nutrition

Precision nutrition aims to tailor diets and interventions to individual physiology, microbiomes and metabolic profiles. Projects can involve microbiome science, personalised food formulations, diagnostic biomarkers and data methods to stratify responses to nutrients. The EIC expects work here to bridge laboratory biology with interventions that can be validated for health outcomes.

Responsible electronics

Responsible electronics includes designing low‑power components, reducing toxic substances in manufacturing, and improving recyclability and circularity in electronics. Research lines may cover halogen‑free etching techniques, sustainable printed electronics, low‑energy nanoelectronics and materials that reduce environmental impact across device lifecycles.

In‑space solar energy

This topic targets technologies for harvesting, converting and using solar energy in orbit. Candidates include high‑efficiency photovoltaic architectures, lightweight deployable solar arrays, energy storage suited to space, and power transfer concepts. The work is intended to strengthen Europe’s resilience in space systems and reduce dependence on non‑European suppliers for critical components.

How winners are supported beyond the grant

The EIC presents its Pathfinder funding as more than grant money. Projects are deliberately selected as portfolios so Programme Managers can encourage cross‑project coordination, data sharing and joint actions. Awardees are offered bespoke coaching and mentoring through the EIC Business Acceleration Services and may be fast‑tracked to subsequent instruments such as EIC Transition or the EIC Accelerator for activities closer to market. The EIC Fund can provide equity support later in the innovation chain where applicable.

A pragmatic assessment and remaining challenges

The EIC’s Pathfinder Challenges channel money to early‑stage science and that is necessary if Europe is to generate new technological options. The funding and portfolio approach address a known gap: risky interdisciplinary research that falls between basic science grants and venture capital. Yet several structural limitations persist. The average Pathfinder grant, at roughly €3–4 million, supports upstream work but is small relative to the capital needed for hardware scaling, pilot manufacturing and market entry. Promising projects will therefore still need to attract significant follow‑on funding from public or private investors. The portfolio model promises synergies but requires significant programme management capacity and mechanisms for IP, data sharing and coordination across independent teams. Lastly, success metrics should not be limited to number of projects funded; they should include follow‑on funding mobilised, demonstrators delivered, standards influenced and the creation of pathways for commercial uptake.

What to watch next

Results for the Pathfinder Open 2024 evaluation were scheduled for summer 2024. For winners of the 2023 Challenge call, the key indicators to track will be how many projects secure Transition awards, how many progress to the EIC Accelerator or EIC Fund investment, and whether the Programme Managers can translate portfolio coordination into shared assets such as datasets, common testbeds or standards. Observers should also watch whether the high volume of Open proposals translates into a wider geographic spread of beneficiaries or whether selection remains concentrated in established research hubs.

For applicants and ecosystem stakeholders the practical takeaways are clear. Apply where technical risk and novelty match the Pathfinder remit. Expect grant support to derisk early science but plan for a multi‑stage financing strategy. Engage Programme Managers early, use the EIC Business Acceleration Services and build deliberate plans for IP protection and investor outreach if the goal is market impact.
