Nuclear Turbines aims to reduce the cost of nuclear power by replacing traditional steam turbine systems with highly efficient high-temperature turbine technology typically used in jet engines and gas-fired power plants, combined with a novel nuclear reactor design. Its compact systems are intended to be deployable "behind the meter" at industrial sites, data centres and manufacturing facilities. The company says this approach can lower generation costs to around one-fifth of today’s nuclear plants and builds on advancements in small modular reactors to address cost and scale challenges. Founded in 2025 and spun out of BAE Systems in partnership with Empirical Ventures' venture studio, the startup is led by Jeremy Owston and Professor Tim Abram. Following a £15m funding round led by IQ Capital, the company plans to use the capital for design, constructing large-scale test rigs and hiring to expand the team. No revenue, user or valuation metrics were disclosed in the articles.

Caudal Energy designs an oscillating foil "Caudal Generator" inspired by marine mammal tail fin hydrodynamics to harvest predictable tidal power using a modular, surface-mounted architecture. Its fin-based platform is engineered to operate efficiently in mid-flow tidal locations (peak flows above 3 knots), expanding the range of viable sites compared with conventional turbine systems that require higher peak flows. The modular design aims to simplify installation, lower maintenance and operational complexity, and reduce levelized cost of energy to be competitive with established technologies such as offshore wind. The technology has reached Technology Readiness Level 5 and is entering full-scale testing at Strangford Lough, with a targeted first commercial deployment in 2028 to reach TRL8. Caudal was founded in 2024 (originally Porpoise Power) based on breakthrough hydrodynamic research from the University of Oxford and is advancing commercial partnerships across utility, industrial and distributed energy markets.

Exergy3 develops ultra-high temperature thermal energy storage systems that convert surplus renewable electricity (including curtailed wind power) into high-temperature heat for industrial applications. The company is led by CEO Markus Rondé and is based in Edinburgh, Scotland. Following the £10M Seed raise, Exergy3 plans to scale manufacturing capacity and expand its team to support broader deployment at industrial sites. Its stated focus is turning excess renewable generation into usable energy rather than letting it go to waste. The company’s current financial update is the newly closed seed financing; no revenue or user metrics were reported in the article.

Nutropy is a French food-tech startup that engineers animal-free casein and other dairy proteins using precision fermentation, then formulates them into B2B powdered ingredients branded as “plug-and-play” solutions for traditional dairy manufacturers. Its flagship offering, a “cheeseable milk” base, can be transformed into cheese and other dairy products that match the taste, texture and nutrition of conventional counterparts while lowering environmental impact. Led by co-founders Nathalie Rolland (CEO) and Dr. Maya Bendifallah (CSO), the company sells to food producers rather than end consumers. With fresh capital in hand, Nutropy plans to scale industrial production of casein, broaden its portfolio of dairy applications, and pursue commercial opportunities across North America, Asia and Europe. The firm has secured public support from French and European programs, including Bpifrance, to complement private investment. Financially, the company closed a €2 million pre-seed round in 2022 and has now added €7 million in new funding, bringing total known equity raised to €9 million.

Vema Hydrogen develops Stimulated Geologic Hydrogen (SGH) technology that produces hydrogen by injecting a catalyst-bearing brine into shallow geological formations where it reacts with iron-bearing minerals. The hydrogen is extracted for use in electricity generation, heat, and production of green chemicals and fuels. The company says SGH enables production in strategically selected locations, reducing exploration uncertainty, logistical challenges, and costs while allowing precise control over gas composition and flow rates. Vema plans to use the funds to develop the first clusters of full-scale SGH pilot wells in North America. The company was founded by Florian Osselin and Pierre Levin and was created at the venture studio Marble. Vema is based in Wilmington, DE.
