Knoxville-based startup Type One Energy announced it has raised $200 million in a Series B funding round. The company plans to use the funds to build a 400-megawatt fusion power plant, aiming for completion by 2034. Their approach involves designing the plant and sourcing components from a network of specialized suppliers to reduce costs.
Moment Energy, founded in 2019 in Vancouver, is transforming used electric vehicle batteries into energy storage solutions. The company is expanding its operations in North America, aiming to categorize its repurposed batteries as domestic products and secure safety certifications from UL. This move comes amid ongoing trade tensions and a growing demand for sustainable energy storage options.
Energy Dome has activated its first commercial-scale energy storage facility in Sardinia, Italy, with a capacity of 200 megawatt-hours, capable of powering approximately 18,000 homes for 10 hours. The company, founded in 2020 and based in Milan, plans to develop up to 30 gigawatt-hours of storage projects across five continents, leveraging its unique carbon dioxide battery technology that does not rely on specific geological formations. While the technology is estimated to be more cost-effective than lithium-ion for longer durations, it currently has only one operational plant and faces efficiency limitations compared to traditional batteries.
X-energy announced its Xe-100 reactor design, which employs helium gas as a coolant to operate at lower pressures and higher temperatures. The reactor uses TRISO fuel pebbles that are resistant to corrosion and melting, and can produce up to 80 MW of electricity or provide industrial heat. The design emphasizes intrinsic safety, as rising temperatures naturally slow the nuclear reaction.
Form Energy has developed a new iron-based battery technology capable of storing energy for up to 100 hours, utilizing a reversible rusting process. The company has begun commercial production at its West Virginia facility, with a 150 MWh system scheduled for deployment in Minnesota in 2027, and has secured multiple deals including a large project with Xcel Energy to power a Google data center between 2028 and 2031. These batteries aim to provide multiday energy storage to support renewable power integration and reduce reliance on fossil fuels.
WeLion New Energy has advanced its semi-solid-state battery technology, achieving an energy density of 824 wh/kg in testing during 2025. The company previously released a battery pack with 360 wh/kg in partnership with Nio, supporting over 1,000 km of range, though production costs limited its scale. Additionally, WeLion is developing batteries for maritime applications and exploring higher energy densities.
The US Supreme Court has started hearing oral arguments in the case of Boulder County v. Suncor Energy and ExxonMobil, which concerns climate change damages and financial liability. The outcome could determine whether local governments can pursue legal action against fossil fuel companies for environmental harm, potentially setting a nationwide precedent. A ruling in favor of the oil companies might limit future climate litigation at the state level.
Greenvolt Power has commenced construction of a 600 MW/2.4 GWh battery energy storage system in Siedlce, Poland, with plans to start commercial operations by late 2027. The project will utilize BYD's battery technology and connect to the national grid via new infrastructure, enhancing grid flexibility and supporting renewable energy integration. Once completed, Greenvolt's total battery capacity in Poland will reach 1 GW with 4 GWh of storage, strengthening its role in balancing renewable power supply and demand.
A CNET writer highlights smart home products discounted during Amazon's October Prime Day sale, including a Tapo two-pack smart plug with energy monitoring priced around $10-$15, and the Google Nest Learning Thermostat (4th gen). The recommendations are based on the writer's own long-term testing of devices for cost savings, convenience and privacy features.
A roundup gathers perspectives from 30 executives across industries on laws and proposed bills shaping their sectors, spanning AI accountability, healthcare policy, tariffs, clean energy and consumer protection. The leaders describe how they are responding to or advocating around legislative changes that affect their companies and customers.
Kodiak AI, founded in 2018, has deployed 35 fully driverless trucks for Atlas Energy Solutions hauling frac sand in the Permian Basin since its Kodiak Driver system launched in December 2024. The company now plans to run driverless trucks on public highways in Texas later this year, operating a 219-mile route between Houston and Dallas for Ikea along Interstate 45.
IEA head Fatih Birol said at the United Nations that the traditional energy trilemma—balancing cost, security and clean energy—is increasingly aligning in favor of electrification, partly due to disruptions from the Iran war raising fossil fuel prices. The IEA's new report finds $100 of electricity now powers an EV nearly three times farther than $100 of gasoline powers a gas car, and buys roughly 40% more heating days via heat pumps than gas boilers.
