Cheesecake Energy

High-Level Overview

Cheesecake Energy is a University of Nottingham spin-out company founded in 2016, developing the eTanker, a modular, containerized energy storage system that stores energy as heat and pressurized air for medium- to long-duration applications.[1][2] It serves commercial and industrial customers, grid operators, and renewable energy sites by solving intermittency issues with wind and solar, enabling reliable on-demand power at 30-40% lower costs than lithium-ion batteries over 25 years, with 65% efficiency, full recyclability, and up to 20 hours of full power output.[1][2][5] The company has raised $5.6M in funding, including a £1M seed round led by Imperial College Innovation Fund, and won recognition at the 2024 Green Awards for its sustainable compressed air energy storage.[1][3]

Origin Story

Cheesecake Energy emerged from research at the University of Nottingham, spinning out in 2016 with founders including Prof. Seamus Garvey (CTO), Dr. Bruno Cardenas (System Design), and Mike Simpson (CCPO/Founder).[1][4] The team, blending academia, industry, and business expertise, focused on affordable long-duration storage to decarbonize electricity grids.[4] Early traction included prototype testing in Nottingham and plans for UK pilot systems, bolstered by seed funding in 2021 to scale manufacturing of the eTanker, which repurposes ex-service truck engines as zero-emission power converters.[1][3]

Core Differentiators

• Sustainable Design and Materials: Uses benign, recyclable materials and repurposed truck engines plus CNG skids for compression, enabling a circular economy with negligible environmental footprint versus lithium-ion's mining impacts and 5-10 year lifespan.[1][2]
• Cost and Performance Edge: Delivers 20+ hours of full power at 65% round-trip efficiency for 25 years, at 30-40% lower lifetime costs than lithium-ion, ideal for time-shifting renewables and grid constraints.[1][2][5]
• Modular and Deployable: Containerized eTanker is safe, fuel-free, easy to operate, and leverages existing supply chains for rapid scaling without custom components.[2]
• Proven Team and Backing: Led by CEO Paul Harris with founders from Nottingham research; board includes ex-CEOs from Tata Motors, Highview Power, and Arup; supported by investors like Perivoli Innovations.[3][4]

Role in the Broader Tech Landscape

Cheesecake Energy rides the global shift to 100% renewable grids, addressing renewable intermittency amid rising solar/wind adoption and grid bottlenecks.[1][5] Its timing aligns with net-zero mandates, falling lithium costs exposing limitations for long-duration needs, and demand for low-carbon alternatives in commercial/industrial sectors.[2] Market forces like policy incentives for decarbonization and circular economy principles favor its mechanical, recyclable tech over battery degradation, positioning it to enable mini-grids and onsite renewables worldwide.[1][4][5]

Quick Take & Future Outlook

Cheesecake Energy is poised to deploy pilot eTankers with UK customers soon, scaling manufacturing with recent funding to capture growing long-duration storage demand.[1][3] Trends like AI-driven grid loads, expanded renewables, and battery supply constraints will amplify its cost/recyclability advantages, potentially influencing ecosystem-wide adoption of hybrid thermal-compressed air systems. As grids evolve toward reliability without rare earths, Cheesecake could redefine affordable green storage, turning intermittent renewables into the dependable backbone of decarbonized power.[2][5]
