In a bold move that’s reshaping the coffee industry, Ray & Jules partnered with CEE to redefine coffee roasting
Ray & Jules set out with a bold ambition: to roast coffee at industrial scale without sacrificing on sustainability or quality. The goal was clear — no use of fossil fuels, and making great coffee that can compete in the specialty market.
CEE answered with a ground-up solution: an energy efficient, high-precision, fully electric roasting platform. The system offers optimal thermal control, delivering better yield and consistent quality while drastically reducing energy consumption.
By combining deep process engineering with sustainable design, CEE enabled Ray & Jules to become the world’s first solar-powered, all-electric roastery — a proof point for what the future of coffee can be.
Built on Chemistry, Powered by Engineering
At the core of this innovation lies a unique combination of disciplines: a profound understanding of the chemistry behind coffee roasting and flavor development, paired with deep expertise in energy-efficient thermal processes and precision engineering. This cross-disciplinary foundation enabled CEE to reimagine the roasting process from the ground up — with energy efficiency, electrification and product quality as guiding principles.
- Energy consumption 2,5x lower compared to traditional batch roasting
- Superior product quality and consistency
- Higher yield from every batch, up to 1,5 % higher compared to batch roasting
Energy efficiency first
CEE’s first priority was to radically reduce energy use in order to make electrification feasible, electricity is more expensive than gas and grid congestion issues needed to be avoided. The roasting system was redesigned from scratch, optimizing every thermal flow to minimize losses. The result is a process that uses just 40% of the energy required by traditional batch roasters — and sets a new benchmark for operational efficiency.
Precision and consistency
Unlike conventional gas-powered systems, the electric platform enables full control over the roasting curve. Temperatures and roasting power can be defined at each point in the roasting curve, feedback is provided at the same level. That precision yields higher quality in every bean, less waste, and better reproducibility — all while offering a gentler roast that preserves flavor integrity. Moreover, the high degree of automation is a solid base for advancement in AI-powered recipe developments.
A Living Lab for Innovation
More than a production facility, the Ray & Jules roastery has become a showcase center for CEE’s sustainable roasting technology. It now serves as a proof point for coffee professionals, brands, and industry leaders who visit to witness first-hand how electric roasting stacks up in quality, efficiency, and environmental impact.
Through live trials using their own green coffee, visitors experience what’s possible — and walk away inspired by a better path forward.
CEE’s unique approach to innovation
How does CEE come to re-imagine industrial processes ? We put first things first, building cleantech around the product and not compromising on energy efficiency. Not dogmatic or afraid to start from scratch, we often wonder why industrial processes like roasting consume so much more energy than what physics dictate. Fuelled by curiosity and a drive to have a positive impact on industry, our solutions go beyond the obvious to achieve unrivalled performance and flexibility. We think, we build and we deliver !
A Shared Vision for the Future of Coffee
CEE’s partnership with Ray & Jules exemplifies how technological innovation and environmental ambition can work hand in hand. By aligning advanced roasting technology with a clear sustainability mission, we’re not just roasting coffee — we’re reimagining what the coffee industry can become.
Together, we’ve proven that great coffee, precise engineering, and a clean energy future can thrive in the same cup.
Ray & Jules
Ray & Jules is on a mission to revolutionize the coffee industry with a 100% electric, solar-powered roasting process and a bold commitment to sustainability. As the fastest-growing coffee company in the EU, they’ve already reached over 35,000 customers with their fair and flavorful brews. Recognized as a "radical vernieuwer" in 2022 and featured in Forbes, the company stands out not only for its product but for its purpose. Ray & Jules exists to prove that great coffee and climate ambition can go hand in hand — inspiring a new standard for how coffee is made, shared, and enjoyed.
