WATERGY GMBH

Their core work

WATERGY GmbH is a German technology SME specialising in thermochemical energy systems — specifically absorption and desiccant-based processes that store, transfer, or recover energy through chemical reactions with water vapour. Their work bridges thermal energy engineering and applied fluid chemistry, developing practical systems for two distinct domains: district-scale heat networks and controlled-environment agriculture. In H2020 projects they have contributed thermochemical fluid expertise and system integration knowledge, not just research. Their company name itself encodes their core proposition: the coupling of water management with energy efficiency.

What they specialise in

How they've shifted over time

In their first H2020 project (2016–2019), WATERGY focused on thermochemical fluids as a tool for district-scale heat distribution — urban infrastructure at the network level. By 2020 they pivoted the same core technology into precision agriculture, applying absorption and desiccant chemistry to solve greenhouse climate and water challenges. The underlying expertise (thermochemical fluid behaviour, absorption cycles) has remained constant, but the application domain has broadened from energy utilities to food production systems.

WATERGY appears to be methodically expanding its thermochemical absorption technology into new sectors — first energy networks, then food production — suggesting future collaborations in industrial process heat, cold-chain logistics, or building HVAC are plausible next steps.

How they like to work

WATERGY participates exclusively as a consortium partner and has never held a coordinator role across either of their H2020 projects, indicating they prefer to contribute as technical specialists within larger teams rather than lead programme management. With 16 unique partners across 10 countries in just two projects, they are active networkers who bring cross-sector reach despite their small size. This profile — specialist contributor in well-networked consortia — makes them a reliable technical partner for teams that need thermochemical process expertise without organisational overhead.

WATERGY has built a network of 16 distinct consortium partners across 10 European countries from just two projects — an unusually broad footprint for a two-project SME. No geographic concentration is evident from the available data, suggesting they engage with whichever consortia best match their technology rather than prioritising national or regional clusters.

What sets them apart

WATERGY occupies a rare niche at the intersection of thermochemical energy storage and practical agricultural engineering — very few SMEs hold credible project track records in both district heat networks and greenhouse climate systems simultaneously. Their Schwedt/Oder base in Brandenburg also places them near Germany's post-coal industrial transformation zone, giving them practical relevance to energy transition projects in the region. For a consortium builder needing a hands-on thermochemical systems company that can connect energy and food sectors in a single partner, WATERGY is a compact but well-networked option.

Highlights from their portfolio

• H-DisNet
  Their largest single grant (EUR 472,469) and earliest H2020 project, establishing WATERGY's credentials in thermo-chemical district energy — a technically complex and capital-intensive domain rarely entered by micro-SMEs.
• TheGreefa
  Demonstrates WATERGY's ability to transfer thermochemical expertise across sectors, applying absorption and desiccant systems to sustainable greenhouse farming — an unusual energy-meets-food cross-over that makes them distinctive in both communities.
