  • In a first, fusion company applies for US grid connection

    Commonwealth Fusion Systems, the first developer of nuclear fusion technology, has applied to connect their planned power plant to the PJM Interconnection grid in Virginia. This move aims to demonstrate the feasibility of delivering low-carbon electricity to customers by the early 2030s. The application process, expected to take four to six years, is the initial step towards integrating the 400-megawatt fusion power plant into the grid. PJM will conduct grid simulation models to ensure the project can reliably provide electricity, marking a significant advancement in the development of fusion technology for sustainable energy solutions.

  • How to electrify greenhouses with semi-transparent PV, heat pumps

    Researchers in Canada found that 69%-transparent crystalline silicon semitransparent PV modules can improve tomato greenhouse yields by up to 38% while maintaining healthy plant growth through beneficial partial shading. Combining rooftop agrivoltaics with heat pumps can fully eliminate fossil fuel heating. Various bifacial STPV technologies were tested in greenhouse conditions for tomato production, with differences in light intensity and spectrum affecting plant growth. The study, published in Energy and Buildings, evaluated agrivoltaic greenhouse systems through five main stages and used software tools to simulate and analyze different greenhouse scenarios. Experimental investigations showed that the selected 69% transparent PV system with a heat pump enabled full electrification of an agrivoltaic greenhouse, covering approximately 13% of the total annual electricity demand. This combination of agrivoltaic fields and partially-powered agrivoltaic greenhouses was seen as a synergistic strategy for sustainable and economically viable production, with the potential to reduce greenhouse carbon emissions and improve crop yields.

  • Cooling PV modules with hydrogel-coated paper

    A Vietnamese research team has developed a low-cost passive cooling system for PV modules using hydrogel-coated paper that combines water flow and interfacial evaporation to reduce operating temperatures. Outdoor tests showed temperature reductions of up to 14 C and efficiency gains of up to 16.8%, with stable operation achieved using both freshwater and natural seawater. The system was tested under real outdoor conditions and showed strong performance, with the hydrogel-coated paper maintaining effective cooling even with natural seawater. The novel passive cooling technique enables convective heat transfer through flowing water and dissipation of latent heat via interfacial evaporation, leading to significant efficiency gains for PV panels. The study involved researchers from various universities in Vietnam and aims to scale up the system for real-world use, focusing on optimizing materials for different climates, enhancing corrosion protection, and integrating energy generation with water treatment.

  • Massachusetts flips on power from Vineyard Wind

    Massachusetts successfully activated long-term power contracts for Vineyard Wind, the first offshore wind project in the country, overcoming setbacks from the Trump administration and a turbine supplier. Court rulings in favor of Vineyard Wind allowed the $4.5 billion project to progress, with turbines now being tested and brought online. The power purchase agreements are projected to save consumers $1.4 billion over their lifetime and have helped stabilize electricity prices during a high-demand winter. Massachusetts Gov. Maura Healey emphasized Vineyard Wind as a crucial component of the state's strategy to reduce energy prices.

  • Money Trees: Paraguay’s Carbon Market Strategy Comes into Focus

    Paraguay is strategically positioning itself to capitalize on the global carbon market by developing a legal framework for carbon credit projects aligned with the Paris Agreement. The country's focus on compliance markets, leveraging renewable energy sources like the Itaipu Dam, gives it a competitive advantage in becoming a regional hub for carbon credit projects. Paraguay is exploring opportunities in clean energy initiatives such as hydroelectricity and green hydrogen, with agreements already in place with countries like Singapore, United Arab Emirates, and Taiwan. While concerns about inequality in land distribution and benefiting local communities exist, the government and private sector are working towards including all Paraguayans in accessing carbon markets, as highlighted in the upcoming Paraguay Carbon Forum set for March 2026 in Asunción.

  • Meta gains early access to 1 GW of space-based solar power

    Meta has signed an agreement with Overview Energy to receive space-based solar power for its data centers, aiming to demonstrate the technology in 2028 and begin commercial power delivery in 2030. This system collects solar energy in space and beams it to existing solar facilities on the ground, offering a 30% power boost and allowing developers to bypass grid constraints and interconnection bottlenecks. The partnership reflects a broader industry shift towards non-grid solutions as companies seek to insulate themselves from grid volatility and meet the power requirements of generative AI. This innovative orbital strategy could revolutionize the way companies access renewable energy and contribute to a more sustainable future.

  • California’s water crisis could turn farmland into massive solar field

    The Westlands Water District in California's San Joaquin Valley is planning to repurpose water-starved farmland into a massive solar-and-battery network through the Valley Clean Infrastructure Plan, aiming to add 21 gigawatts of solar and battery capacity across 136,000 acres. This project, the largest of its kind globally, will help address the water crisis, lower energy costs for farmers, and comply with new state groundwater limits. By selling solar power through the California grid, the district hopes to reduce energy costs for farmers and keep farming viable, while also providing clean electricity to the state. This innovative solution not only helps farmers adapt to changing climate conditions but also mitigates the impacts of climate change on agriculture in the region.
