Lydian has developed PIVOT™, a full‑stack, modular production platform that integrates proprietary reactors, catalysts, process design, software, and balance‑of‑plant into factory‑built modules for synthetic aviation fuel. The platform is designed to cut project capital costs by more than 50% versus competing technologies, operate flexibly with intermittent renewable electricity, and reduce lifecycle greenhouse gas emissions by up to 95%. Lydian produces ASTM‑approved, drop‑in sustainable aviation fuel from captured CO2 and hydrogen and is positioning PIVOT to enable faster, lower‑cost deployment of synthetic fuel projects. The company operates a tonne‑scale pilot plant at its Boston R&D Center of Excellence and plans a commercial demonstration facility targeted for 2028 with first full‑scale commercial deployment expected in 2030. Financially, the company completed a $43 million Series A to support commercialization and deployment activities.

Foundation Alloy commercializes a solid-state alloying technique that repeatedly smashes metal powders together to create homogeneous alloys that traditional melting processes cannot achieve. The process reportedly uses around an order of magnitude less energy than conventional melting-based alloying and enables combinations of elements with very different melting points. The company has been selling bespoke metals in small batches and is running pilots with customers in automotive, aerospace, semiconductor, defense, luxury watches, and cutlery. Early commercial products include tooling parts for automakers and parts targeted at drone supply chains within defense. Foundation Alloy says it is currently constrained by production capacity rather than demand and plans to scale to several tons per week by 2027 using proceeds from its Series A. Its technology builds on about 20 years of research led by Tim Rupert and Chris Schuh, and the company is led by CEO and co-founder Jake Guglin.

NewOrbit develops purpose-built satellites and proprietary propulsion technology to enable sustained operations in very low Earth orbit (200–300 km). The company says its design is intended to withstand VLEO environmental challenges such as atmospheric drag and atomic oxygen and to operate for up to five years. NewOrbit targets applications including higher-resolution Earth observation and low-latency satellite connectivity. Founded in 2021 and headquartered in Reading, the startup plans to construct the NEO Production Complex in 2027 to manufacture its first commercial satellite. It expects to launch that satellite in 2028 and increase production as operations scale. The company has raised a Series A led by Voyager Ventures and participation from angels, a family office, and existing investors.

Tem operates two complementary businesses: Rosso, an AI-driven transaction engine that pairs electricity suppliers with buyers, and RED, a "neo-utility" that uses Rosso to sell power directly to customers. By collapsing the many intermediaries in traditional energy trading, its machine-learning and LLM models aim to bring end-user prices closer to wholesale rates, promising up to 30% savings. The company has already signed more than 2,600 business customers in the U.K., including Boohoo Group, Fever-Tree and Newcastle United FC, and focuses on renewable and distributed generation assets that suit its algorithms. Tem intentionally built RED first after legacy utilities showed little interest in licensing Rosso, but it plans to open the platform to other utilities once scale is proven. Management says the business is currently profitable on its own but is pursuing rapid growth with an eye toward a future IPO. Fresh capital will fund geographic expansion to Australia and the U.S., beginning in Texas. A recent Series B financing values Tem at over $300 million, underscoring investor confidence in its infrastructure-as-a-service approach to energy markets.
