  • 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.

  • Firm solar and storage costs fall to $54/MWh, says IRENA

    IRENA's new report highlights the economic and strategic advantages of round-the-clock solar and wind paired with battery storage, showing that they are cheaper than new fossil fuel generation in high-quality resource regions. Firm levelized costs of electricity for solar-plus-storage range from $54/MWh to $82/MWh, compared to $70/MWh to $85/MWh for new coal in China and over $100/MWh for new gas globally. The decreasing capital costs have made dispatchable "anytime" solar electricity commercially viable in regions with high PV potential, allowing for more reliable and consistent renewable energy generation. These advancements in renewable energy systems emphasize their reliability, resilience, and ability to optimize grid connections while reducing price volatility, making them key solutions in the fight against climate change.

  • Dominion upbeat on offshore wind as cost estimate eases, sales rise

    Dominion Energy is prioritizing the completion of the Coastal Virginia Offshore Wind project, the largest wind farm in the US, by June 2027. The project is 75% complete with 9 out of 176 turbines installed, with an estimated capital budget of $11.4 billion and expected fuel savings of $5 billion over 10 years. Dominion's focus on transmission and distribution infrastructure, along with the growth in data center capacity, is driving significant regulated investment needs. Additionally, Dominion's Virginia territory will see an increase in gas generation, solar, and energy storage spending, with more opportunities for regulated capital deployment in the early 2030s. A new Virginia law requires Dominion to petition for 20 GW of energy storage projects by 2040, up from 3 GW by 2035, which will be reflected in the company's capital update next year.
