Oxfordshire-based Ionech, a clean-energy tech firm creating a course of to harness thermal vitality from ambient air to generate electrical energy, has obtained a €2.3 million (£2 million) Seed funding ClimateTech investor Elbow Seashore.
This funding is mixed with a €807k (£700k) Innovate UK Grant, will allow the corporate to advance its Air Voltaic Cell expertise from lab-scale improvement into real-world pilots over the subsequent 24 months, and progress joint improvement agreements with early-adopting companions.
Thomas Kirk, co-founder of Ionech, shares with EU-Startups: “Vitality sits on the basis of the expertise stack. At Ionech we’re constructing a platform vitality expertise that can essentially change the distribution and consumption of electrical energy in vitality intensive industries. We’re wanting ahead to our partnership with Elbow Seashore as we scale our vitality {hardware} expertise to reinforce grid resilience, scale back transmission price and ship tangible price financial savings for the end-user.”
Within the wider European clean-energy and ClimateTech panorama of 2025, Ionech’s Seed spherical aligns with a gentle move of early- and growth-stage capital into applied sciences targeted on electrification, vitality effectivity and grid resilience.
In Sweden, Stockholm-based Aira raised €150 million to speed up the electrification of residential heating, reflecting robust investor urge for food for scaling confirmed clean-energy {hardware}. France has additionally seen exercise at a later stage, with Paris-based Spark Cleantech securing €30 million to help cleaner vitality options for heavy business.
On the earlier finish of the market, Spain’s Clevergy raised €3.2 million to scale its sensible vitality platform, whereas Dutch startup Zympler closed a €1.5 million spherical targeted on grid optimisation, and Italy’s Renewcast secured €1 million to develop AI-driven renewable vitality forecasting.
Alongside company-level rounds, devoted capital can also be being deployed through specialist funds, equivalent to Future Energy Ventures, which closed a €205 million second fund to again energy-tech startups throughout Europe.
Taken collectively, these bulletins level to properly over €400 million shifting by way of adjoining clean-energy sectors throughout this era, positioning Ionech’s funding as a part of a broader sample of continued funding into each novel vitality {hardware} and enabling vitality applied sciences.
Jonathan Pollock, CEO of Elbow Seashore, mentioned: “Ionech represents the form of daring innovation we goal to help at Elbow Seashore. Vitality demand is rising, pushed by amongst different issues, cooling techniques and AI. Ionech is creating methods to harness clear vitality from ambient air. Their Air Voltaic Cell expertise has the potential to scale back reliance on the grid, decrease vitality consumption, and ship tangible advantages throughout the actual economic system. We’re excited to associate with Ionech as they advance their expertise to market.”
Based in 2016 and primarily based within the Harwell Science and Innovation Campus, Ionech is a clear vitality firm turning the latent vitality of ambient air into electrical energy with its Air Voltaic Cell. Designed for high-demand functions and scalable for the grid, their expertise reportedly affords low-maintenance, sustainable energy options that scale back vitality prices and carbon emissions.
Ionech’s Air Voltaic Cell expertise makes use of excessive voltage pulses and area electron emission to generate superoxide ions and convert the thermal and chemical potential vitality of ambient air into electrical vitality.
Nathan Owen, co-founder and Managing Director of Ionech, says: “We’re partnering with Elbow Seashore to advance the event of our Air Voltaic Cell expertise. Their funding permits the transition from lab-scale improvement to real-world pilots, together with preliminary work with CCEP’s cooler fleet. It additionally accelerates our path to market and deployment throughout energy-intensive functions, equivalent to HVAC and information centres, with the potential to scale back vitality consumption, emissions, and reliance on the grid at scale.”
Ionech goals to combine the expertise initially into high-energy demand gadgets equivalent to industrial refrigeration, air con and air flow models, which account for over 1 / 4 of worldwide vitality consumption, and ultimately at grid scale, saving megatons of CO2 and decreasing vitality payments.
Companions embody Coca-Cola Europacific Companions (CCEP), the place Ionech’s expertise might considerably scale back the carbon footprint of drinks coolers amongst different functions. CCEP was an early investor in Ionech, which plans to display its first commercial-ready system by 2027.
Joe Franses, VP Sustainability at CCEP, provides: “We proceed to be excited in regards to the potential of the expertise that Ionech is creating, and the way it might help CCEP in accelerating in direction of our sustainability objectives. This newest funding brings us nearer to that potential.”
