SUNAMP LIMITED

Their core work

Sunamp is a Scottish SME specializing in thermal energy storage, particularly phase-change material (PCM) based heat batteries for residential and district-level applications. They contribute compact thermal and electrical storage solutions to EU-funded smart energy and building retrofit projects. Their technology enables demand-side flexibility, grid balancing, and integration of renewable energy sources into buildings and energy communities across Europe.

What they specialise in

How they've shifted over time

In their earlier H2020 work (2016–2018), Sunamp focused on smart grid components — demand-side management, demand-response, e-mobility integration, and decentralised energy community platforms. From 2019 onward, their involvement shifted decisively toward thermal storage materials (phase-change and thermochemical), positive energy districts, and large-scale decarbonization of islands and coal regions. This trajectory shows a company moving from general smart-energy participation toward deep specialization in compact heat storage as a key enabler for district and community energy transitions.

Sunamp is concentrating on compact thermal storage as a critical building block for positive energy districts and island decarbonization, positioning them for Horizon Europe calls on clean energy transitions.

How they like to work

Sunamp exclusively participates as a partner — never as coordinator — which is typical for a technology SME contributing a specific product or capability to larger consortia. With 155 unique partners across 20 countries from just 6 projects, they consistently join large Innovation Action consortia (all 6 projects are IAs). This makes them an accessible, experienced partner who integrates well into big multi-country teams without demanding a leadership role.

Sunamp has built an extensive network of 155 unique consortium partners across 20 countries through 6 large Innovation Action projects. Their geographic reach spans broadly across Europe, with involvement in island energy systems (SMILE, IANOS) and urban district projects (RESPONSE) suggesting connections in Mediterranean, Nordic, and Central European regions.

What sets them apart

Sunamp offers a rare combination: a product-stage SME with real thermal storage hardware (heat batteries) rather than just research or consulting. Their consistent presence in large-scale demonstration projects means their technology has been tested in real buildings and energy communities across diverse European climates. For consortium builders, they bring a deployable storage component that bridges the gap between renewable generation and actual heat demand in buildings.

Highlights from their portfolio

• SMILE
  Largest EC contribution (€693,856) — a flagship island energy systems project covering smartgrid, storage, e-mobility, and demand-response across multiple European islands.
• RESPONSE
  Addresses positive energy districts and coal regions in transition — directly aligned with the EU Green Deal and Sunamp's strategic pivot toward district-scale decarbonization.
• MiniStor
  Most directly aligned with Sunamp's core product — developing minimal-size combined thermal and electrical storage for residential installation using phase-change and thermochemical materials.
