Both ReUseHeat and REWARDHeat explicitly target waste heat as a primary resource, with OPES contributing process energy expertise across urban and industrial heat sources.
OCHSNER PROCESS ENERGY SYSTEMS GMBH
Austrian heat pump engineering company specialising in waste heat recovery, district thermal networks, and geothermal energy integration for urban energy systems.
Their core work
Ochsner Process Energy Systems GmbH (OPES) is an Austrian engineering company specialising in heat pump technology and thermal energy systems for industrial and urban-scale applications. Their core commercial work sits at the intersection of process heat engineering and district energy infrastructure — designing and integrating systems that extract usable heat from low-grade or waste sources. In their EU project work, they have contributed heat pump and process energy expertise to large Innovation Actions demonstrating how cities can tap unconventional heat sources — datacenters, hospitals, sewage networks, metro tunnels, and geothermal reservoirs — to feed competitive district heating and cooling networks. The "Ochsner" in their name connects them to one of Austria's established heat pump technology families, suggesting they bring both engineering depth and commercial product knowledge to consortium roles.
What they specialise in
REWARDHeat focuses directly on making district heating and cooling networks competitive through renewable and waste heat inputs; ReUseHeat targets upstream investment in urban excess heat feeding such networks.
The company name and project roles indicate they are a practitioner in heat pump and thermal energy systems, not a research-only participant, across both funded projects.
REWARDHeat (2019–2024) introduced geothermal energy as a keyword alongside waste heat, signalling an expansion beyond purely urban anthropogenic heat sources.
ReUseHeat explicitly targeted new investment models and business case development for urban waste heat recovery, not just technical demonstration.
REWARDHeat keywords include digitalisation and sector coupling, indicating OPES is engaging with integrated energy system management beyond pure thermal engineering.
How they've shifted over time
In their earlier H2020 work (ReUseHeat, 2017), OPES focused on the upstream challenge of urban waste heat recovery: identifying viable sources — hospitals, datacenters, sewage systems, metro networks — and building the investment and business case logic needed to unlock those sources for district networks. Their more recent project (REWARDHeat, 2019) shifts from source identification toward system integration and competitiveness, with geothermal energy joining the mix alongside digitalisation and sector coupling as explicit themes. The trajectory is from "how do we justify and demonstrate waste heat recovery" toward "how do we build optimised, digitally managed, multi-source district thermal networks at scale."
OPES is moving toward digitally-enabled, multi-source district thermal systems that combine geothermal, industrial waste heat, and sector coupling — making them a relevant partner for smart city energy infrastructure projects in the 2024–2030 Horizon Europe cycle.
How they like to work
OPES has participated exclusively as a consortium partner, never as project coordinator, across both their H2020 projects — both large Innovation Actions with extensive international consortia. With 48 unique partners across 12 countries from just two projects, they operate comfortably in large, multi-national consortia rather than small bilateral partnerships. This profile suggests they join as a specialist contributor bringing heat pump or process energy know-how that broader-purpose consortia need but don't house internally.
OPES has built a notably broad network for an organisation with only two projects — 48 unique consortium partners across 12 countries, consistent with participation in large pan-European Innovation Actions. Their network is geographically diverse across Europe, though no dominant bilateral partner relationship can be identified from this dataset.
What sets them apart
OPES occupies a specific niche as a private engineering company with commercial heat pump product roots that participates in EU research as a practitioner, not a researcher — they bring real-world process energy system knowledge that academic and research-institute partners typically lack. For a consortium building a district energy or urban heat recovery project, OPES represents the "industry demonstrator" profile: a company with both the technical credentials and the commercial incentive to actually implement what the project proposes. Their Austrian base also positions them well for Central European geothermal and industrial waste heat applications.
Highlights from their portfolio
- ReUseHeatOPES's highest-funded project (EUR 334,297 EC contribution), targeting four distinct urban heat source types simultaneously — hospital, datacenter, sewage, and metro — making it one of the broadest urban waste heat demonstration efforts in H2020.
- REWARDHeatA longer-horizon project (2019–2024) that expanded OPES's portfolio into geothermal integration, sector coupling, and digitalisation — marking a clear technology scope upgrade from their earlier work.
