Ambient Works creates air quality monitors that protect respiratory health by tracking particulate matter, VOCs, CO2, temperature, and humidity in real-time. Poor indoor air quality contributes to asthma, lung disease, and reduced cognitive performance, particularly affecting vulnerable populations in homes and workplaces. Building on this foundation, Ambient Works is integrating these monitors into building management systems to help businesses achieve Net Zero goals. The AI-powered platform provides context-specific recommendations and automated HVAC optimization, enabling facilities to reduce energy consumption while maintaining superior air quality. Ambient Works proves that healthy buildings and sustainable buildings are complementary goals, not competing priorities.
Calora is developing a thermal energy storage system to replace domestic gas boilers. By storing heat during periods of low cost and low carbon intensity electricity, then releasing that heat on demand, Calora reduces household emissions and energy costs whilst providing a flexible demand asset to the electricity system.

Developed through years of real-world testing in live properties, Climabox supports Future Homes Standard goals, improves occupant wellbeing, and makes net-zero living more affordable, scalable and practical for homeowners, developers and social housing providers across the UK.
Corrie Energy’s Latitude40 is a patented solar tracker engineered for European latitudes where existing standard trackers are uneconomic. Led by a team with 90 years of sector experience, Corrie addresses this market gap—where 30% of global solar markets rely on inefficient static panels—using novel "twist" kinematics to increase annual energy yields by up to 30%.
Operating a B2B model, we employ a Hardware-as-a-Service (HaaS) approach, securing recurring revenue via operational software subscriptions. By empowering regional installers, Corrie delivers high-value peak power, bypassing grid constraints and transforming project returns for commercial and residential end-users.
Eskimo, founded in 2001, designs and manufactures advanced heat exchangers and radiators/towel warmers, mostly for building heating. In addition, Eskimo, in collaboration with the University of Birmingham, has developed an innovative Thermal Energy Storage (heat battery) solution capable of directly replacing the gas boiler and decarbonising building heating. Eskimo’s latest R&D includes heat recovery for data centres – turning waste heat into warm homes.
In 2025 Eskimo invested £0.5M in a new solar-powered 12000ft2 manufacturing and R&D facility in Kitts Green, Birmingham and set up a distribution subsidiary in New Jersey in the US. Exports now account for 49% of revenues.
FLOAT Energy is a software company reducing the cost of green hydrogen by turning hydrogen production plants into flexible, grid-responsive assets. FLOAT’s real-time optimisation platform automatically controls electrolysers in response to live power prices, carbon intensity, and plant constraints, cutting electricity costs while maintaining green compliance and reducing curtailment. By combining deep domain expertise with advanced optimisation, FLOAT monetises electrolyser flexibility to improve hydrogen producer margins, extend asset life, and support a more resilient, renewable-led energy system.
Planarific accelerate Net Zero transition of the built environment with spatial AI, delivering granular property insights at scale. Our Software-as-a Service (SaaS) platform delivers semantic 3D models with building typological analytics and granular component-level insights for thousands of homes at a time.
Using proprietary AI, we convert imagery captured from the air and on the ground into accurate, semantic 3D building models, deriving both quantitative and qualitative insights. By embedding architectural knowledge with machine learning, we generate typological analytics that discover and categorise building design, enabling scalable solutions for survey, design, construction.
Pure energy (REGen) Ltd. exists to connect businesses and our community to a low cost sustainable future.
We design, select, install and support the adoption of renewable energy technology including electric vehicle chargers, solar PV, battery storage and low-carbon heat networks.
Our key innovation is the EnergyBox™, an ultra-efficient low-carbon heating product, incorporating a solid state heat pump and controls within a sustainable enclosure, connecting ground-source systems to properties more effectively and affordably. Designed for broader deployment and reduced installation complexity, this product supports UK decarbonisation goals and scalable adoption of heat-pump technology.
The Birmingham Centre for Energy Storage (BCES) is driving the commercialisation of e-Thermal Bank, a thermochemical energy-storage technology developed by Professor Li’s group to decarbonise public-sector heating. Yi Cheng, Research Fellow at BCES, leads this commercialisation, focusing on market validation, stakeholder engagement, and real-world demonstration projects. He collaborates closely with industry partners, local authorities, and energy companies to translate research innovation into deployable solutions. By advancing demonstration pathways and supporting spinout formation, Yi and the BCES team are positioning e-Thermal Bank as a scalable, cost-effective solution for sustainable heating systems, enabling the transition to low-carbon energy infrastructure.
At Unitech Synergies Limited, we develop innovative solutions that promote sustainability and establish new technological benchmarks. Our mission is to reduce carbon footprints, accelerate the clean energy transition, and support the global net-zero agenda through impactful, environmentally responsible technologies. We focus on minimising fossil fuel dependence and developing pioneering projects like TOVENVOR—our refrigerant-free cooling system engineered for exceptional energy efficiency. Through rigorous design, validation, and commercialisation, we are redefining the future of cooling technology and demonstrating our commitment to sustainable progress and environmental stewardship.
Wrapt delivers an end to end home retrofit service across the Yorkshire region. We provide home energy advice, design, and retrofit delivery through our in house construction team. We currently deliver insulation and fabric measures directly and work with a range of partners to enable the delivery of whole house retrofit or more integrated measures. Alongside delivery, Wrapt is developing innovative retrofit solutions and services specifically for solid wall properties. This part of the housing stock is significantly underserved, despite representing a major share of homes with poor energy performance. We believe that innovation is essential to overcoming the technical, commercial and delivery barriers to scaling retrofit in older and traditional buildings.
4SB Mobility is developing the UK’s first fully autonomous battery swapping system for EVs and Light Commercial Vans (LGVs). Our innovative technology delivers up to 90 miles of range in under two minutes, without relying on grid-heavy rapid charging or complex vehicle modifications.
