Voltfang develops high-performance European battery storage systems built from requalified EV batteries for industrial, commercial and grid-scale customers. Its core product pairs energy-dense battery modules with an intelligent energy management system, Venma, which uses AI to maximise self-consumption, lower electricity costs and enable participation in energy markets. Customers include Aldi Nord, Alba Group, Fiege Logistik and Goldbeck. The company opened the "Voltfang Future Fab" in Aachen to scale production and enable capacity up to 1 GWh, and aims to deliver an additional 250 MWh of storage across Europe by the end of 2026. Storage capacity grew from 5 MWh in 2023 to 20 MWh in 2024, and Voltfang targets supporting the replacement of the Weisweiler coal-fired power plant by 2030. By using second-life and surplus batteries sourced from the European automotive industry, the company seeks to reduce reliance on Asian supply chains and foster a resilient European battery industry. Voltfang develops green energy storage systems built using requalified electric vehicle batteries, pairing hardware with an advanced Energy Management System. The company aims to broaden its product offerings and invest further in its EMS to maximize battery performance. Voltfang targets commercial/industrial and grid-scale applications and emphasizes circular-economy principles and reuse/second-life concepts. Management plans to deploy an additional 40 MWh of battery capacity by 2025. The company recently completed an oversubscribed financing round, which it closed within three months, strengthening its growth outlook and market position in sustainable energy infrastructure. Voltfang, based in Aachen, builds stationary energy storage systems from used electric vehicle batteries and uses AI-based software to evaluate battery longevity. Its operating system and continuous monitoring aim to make second-life batteries as durable as new ones, backed by a 10-year "Batteryflat" guarantee. The company has completed successful pilot projects in Germany and lists Aldi NORD and Schaltbau among its clients. Voltfang says the systems can be intelligently deployed to amortise batteries quickly and support grid stability amid rising electrification. Management highlights the ability to connect urgently needed capacity to the grid to help avoid blackouts. The company has raised €5 million to scale its production.

Gradyent offers a real-time Digital Twin Platform that creates a digital copy of entire heating and cooling grids, integrating geographical, weather, and sensor data with physics-based models and AI. The platform lets energy providers optimise system performance, increase operational control, simulate future scenarios, and coordinate multiple energy carriers including heating, cooling, electricity and CO₂. Gradyent reports its technology can reduce CO₂ emissions by up to 10%, lower operational costs, and save up to 2% of capital expenditures; an offline analysis helped Helen close a coal plant, cutting Helsinki heat-production emissions by up to 40%. The company partners with leading energy firms across more than 35 European cities, including Veolia, Shell and Helen, and is piloting industrial use cases such as Shell’s steam grid in Rotterdam. Gradyent will use new funding to expand its Digital Twin Platform, grow its team and accelerate global growth to optimise and transform heating and cooling grids worldwide. Financially, the company has just closed a major growth round to support that expansion. Gradyent is a Dutch climate-tech company founded in 2019 in Rotterdam that builds Digital Twin software to help heating companies optimise district heating systems. Its platform creates a digital copy of a physical heat system by combining geographical, weather and sensor data with physical models and AI. The software enables real-time optimisation and simulations of future situations, which the company says saves on average 20% heat loss, 10% CO2 emissions and 5–10% fuel costs. Gradyent aims to increase the efficiency of existing systems and accelerate the transition to more sustainable, integrated energy systems to deliver affordable, reliable heat. The company has brought in €10 million in funding to support those efforts. Eneco, a long-time customer, joined the round alongside existing investors Capricorn Partners, ENERGIIQ and Helen Ventures.

LiveEO develops satellite-based monitoring systems and analytics to track risks along linear infrastructure corridors, including pipelines, railways, and power lines. Its Twinspector project is a dual-satellite constellation designed to capture high-resolution and three-dimensional imagery tailored to long, narrow infrastructure routes. The company intends Twinspector data to integrate with its existing analytics platforms to help operators detect threats like unauthorized construction, excavation, and vegetation encroachment earlier. LiveEO is developing the system with European partners and positions the project as part of expanding commercial Earth observation capabilities for infrastructure monitoring. The company’s current disclosed financing activity includes ESA program funding through the InCubed program to support Twinspector’s development.

Enspired operates a fully automated, in-house trading platform that simultaneously optimises batteries and other flexible power assets across wholesale, control reserve and ancillary service markets. Its core value proposition is to monetise asset flexibility quickly, reducing time-to-market for BESS owners while maximising revenue opportunities in Europe’s short-term power markets. Over the past 12 months the company entered six new European markets and now manages more than 1 GW of BESS capacity, underscoring rapid growth and scale. Management positions the platform’s AI capabilities as a critical lever to accelerate the global energy transition and alleviate bottlenecks created by rising renewable penetration. Certified revenue disclosures have been published to demonstrate commercial leadership, though absolute figures were not provided. Looking ahead, Enspired plans to extend its multi-market optimisation model into Asia and the United States, beginning with a partnership with Banpu NEXT in Japan. The newly secured funding will finance continued product innovation, geographic expansion and the rollout of additional AI-powered use cases.
