Transaera, a MIT spinoff, manufactures energy efficient rooftop air conditioning systems using MOF technology to remove moisture separately from cooling, resulting in 40% less energy usage compared to traditional systems. The systems cost 20% more but pay for themselves in energy savings within two years, with a useful life of 15 years. Metal-organic frameworks, a new class of materials, contribute to the energy efficiency gains by extracting moisture from the air. The company has partnered with manufacturers to install their systems in buildings, including a multi-year deal with Amazon to help achieve net-zero emissions by 2040. As more people and companies understand the benefits of MOF technology, the technology is expected to scale quickly, with Transaera systems offering rapid recapture of the extra cost and designed to fit seamlessly into existing infrastructure.

US Startup Crosses The Bridge Between SAF & Powdered Milk
The global fuel crisis sparked by the Iran War has led to a surge in demand for alternative fuels, including sustainable aviation fuel (SAF). Texas-based startup Syzygy Plasmonics has developed a light-operated biogas reactor to produce synthetic fuels from biogas without combustion, renewing interest in producing fuels from renewable feedstocks for national defense and economic security. Syzygy's focus on sustainable and resilient fuel production includes a project in Uruguay aiming to produce SAF with significantly lower emissions than conventional fuel, with plans to scale up production and establish a competitive business model within the SAF field. The company has also signed agreements to license its bio-based solutions for significant fuel production volumes, with federal energy policymakers open to renewable resources like biomass, geothermal energy, and hydropower. The Iran war has contributed to closing the cost gap between sustainable aviation fuels and traditional fuels, making Syzygy's biogas-to-fuel SAF system increasingly attractive in the market.

AI Data Centres Need Big Batteries But Lithium Isn’t Fit-For-Purpose
The biggest constraint facing AI data centre expansion is storage and the unique way they use power, leading to unpredictability in drawing electricity from the grid. Traditional generation sources like coal and nuclear may still be necessary due to the volatile energy demand of AI data centres. Data centres require buffering capacity to reconcile intermittent supply with intermittent demand, with lithium-ion batteries degrading rapidly under constant cycling. Flow batteries offer a solution by allowing energy and power capacity to scale independently, enabling relentless cycling without degradation typical of lithium-ion systems. The world's renewable build-out is accelerating, but most large-scale batteries remain short-duration systems, highlighting the need for innovative storage solutions for AI-driven data centres. Investing in storage technologies designed for high-cycle operation can help harness renewable energy and prevent the reliance on fossil fuel backup, ultimately allowing AI data centers to contribute to a clean energy future.
