Their core work

IEO is a Polish private company specializing in renewable energy research and consultancy, with a strong focus on thermal energy storage and consumer engagement in clean energy transitions. They bring expertise in bio-based phase change materials for building-level heat storage and in policy frameworks that support solar district heating and renewable energy co-ownership. Their work bridges technical R&D on compact storage systems with market-facing efforts to mobilize investment and empower energy consumers.

What they specialise in

How they've shifted over time

IEO began with policy-oriented work on solar district heating markets (SDHp2m, 2016) and consumer energy engagement (SCORE, 2018), then shifted toward deeper technical R&D with ComBioTES (2019), their largest and longest-running project on bio-based thermal storage materials. This trajectory shows a move from market support and policy advisory toward hands-on materials science and thermal engineering. The growing technical depth in storage technologies suggests IEO is building capabilities that go beyond consultancy into applied R&D.

IEO is moving from renewable energy policy support toward applied R&D in compact thermal storage — expect them to seek partnerships in building-integrated energy systems and advanced materials.

How they like to work

IEO has exclusively participated as a consortium partner, never as coordinator, suggesting they contribute specialized knowledge rather than leading large-scale project management. With 41 unique partners across 12 countries from just 3 projects, they operate in mid-to-large consortia and have built a broad European network. This makes them a reliable, low-friction partner to bring into new consortia — experienced in multi-country collaboration without demanding a leadership role.

IEO has collaborated with 41 unique partners across 12 countries, giving them a wide European network relative to their small project portfolio. Their partnerships span multiple EU member states, likely concentrated in Central and Western Europe given their Polish base and energy-sector focus.

What sets them apart

IEO combines renewable energy policy expertise with emerging technical capabilities in thermal storage materials — a rare dual profile for a Polish SME. Their transition from market-support CSA projects to hands-on RIA work on bio-based phase change materials positions them as a bridge between policy understanding and technical delivery. For consortium builders, they offer a Polish partner with genuine energy storage R&D credentials and experience navigating EU energy policy landscapes.

Highlights from their portfolio

• ComBioTES
  Their largest project (EUR 275,818) and their first RIA — marks IEO's shift into applied R&D on compact bio-based thermal storage for buildings.
• SCORE
  Focused on consumer co-ownership in renewables and demand-side flexibility, showing IEO's engagement with the social and market dimensions of the energy transition.
