Heirloom Raises $150 Million Series B to Rapidly Scale Commercial Direct Air Capture
Heirloom, America’s leading Direct Air Capture (DAC) technology provider, has raised $150 million in Series B funding. The round was co-led by Future Positive, and Lowercarbon Capital - which also invested in Heirloom’s Series A. A range of new industrial investors, including Japan Airlines Co., Ltd., Mitsubishi Corporation (Americas), Mitsui & Co., Ltd., and Siemens Financial Services, representing difficult to decarbonize sectors of the economy – automotive, shipping, aviation, and advanced manufacturing — also participated. This is a strong vote of confidence in Heirloom’s ability to be a leading pathway to net zero. The funding will be used to continue to drive down the cost of the technology, develop additional projects and provide the funding needed to subsequently access infrastructure capital.
New investors in Series B include: Future Positive, H&M Group, Japan Airlines Co., Ltd., Mitsubishi Corporation (Americas), Mitsui & Co., Ltd., MOL Switch LLC, Quantum Innovation Fund, and Siemens Financial Services among others. Repeat investors include leading climate and carbon removal investors like Ahren Innovation Capital, Breakthrough Energy Ventures, Carbon Direct Capital, Lowercarbon Capital, and MCJ Collective.
Since its founding in 2020, Heirloom has progressed rapidly to become one of the world’s leading DAC companies. Heirloom is part of the team building Project Cypress — a Department of Energy supported DAC Hub, which is eligible for up to $600 million in government funding, and which will bring one million tons of yearly CO2 removal capacity to Louisiana and will create nearly 1,000 new jobs. Heirloom has received strong bi-partisan U.S. political support, as demonstrated by their recently unveiled plans for a number of Louisiana facilities, including an initial 17,000 ton facility set to be operational in 2026. Late last year, Heirloom began operating North America’s first commercial DAC facility in Tracy, California, shortly after signing one of the largest CO2 removal deals to date with Microsoft. The company has also signed deals to provide carbon removal to Stripe, Meta, Shopify, JPMorgan, McKinsey, Workday, H&M Group, Autodesk, and others.
Acceleron Fusion Secures $24M Series A Led by Lowercarbon Capital and Collaborative Fund to Revolutionize Clean Energy with Muon-Catalyzed Fusion
Acceleron Fusion, a pioneer in muon-catalyzed fusion energy, has closed a $24 million Series A funding round. The round was co-led by Lowercarbon Capital and Collaborative Fund. This funding marks a significant step in advancing a breakthrough fusion technology that could redefine the future of clean energy while enhancing energy security and independence.
The funding will fuel Acceleron’s efforts to advance its unique approach to clean, safe, and abundant energy. Traditional fusion machines require extreme temperatures of 100 million degrees Celsius. Acceleron’s technology uses muons—heavy subatomic particles—to achieve fusion reactions at temperatures below 1,000 degrees Celsius. This approach could speed the transition of fusion from the lab to practical, deployable power plants. Muon-catalyzed fusion, first discovered in the 1950s, is a proven and well-understood physical process. In the mid 1980s, several groups worldwide demonstrated more than 100 fusion reactions per muon, raising the possibility that the process could be used to generate energy. However, calculations done at the time concluded that it would take more energy to power the muon source than could be released by the fusion.
Acceleron is developing an intense, high-efficiency muon source to produce beams of muons using significantly less energy than current facilities, and a high-density fusion cell to allow each of these muons to catalyze larger numbers of fusion reactions. The company is building on decades of previous work in muon production and muon-catalyzed fusion by university and national lab researchers – and leveraging recent advances in materials science, computer simulation, and machine learning to develop the technology to the level of efficiency needed for energy production.
Matter Intelligence Emerges from Stealth with $12 Million Seed Funding to Revolutionize Remote Sensing and Global Perception
Matter Intelligence, a California-based remote sensing startup, has emerged from stealth, unveiling its plans to launch space sensors capable of capturing never-before-seen data about all matter on Earth, from surface to atmosphere. Matter specializes in advancing sensor infrastructure that captures incredibly detailed, beyond-visible data of both natural and artificial materials – creating the most comprehensive “extreme resolution” Earth observation dataset ever compiled. This data will power industries and helps AI models better understand and predict real-world events like never before. The startup has secured $12 million in seed funding led by Lowercarbon Capital, with participation from Toyota Ventures, Pear, Mark Cuban, and E2MC. The funding will accelerate the development of Matter’s sensing infrastructure.
Matter Intelligence’s sensors use hyperspectral imaging, a method that captures thousands of narrow spectral bands of light to distinguish unique material properties. This allows Matter to detect and classify objects and materials that are invisible to traditional optical, radar, or multispectral sensors. Matter’s sensors, designed for deployment on satellites, drones, and aircraft, will offer the world’s first sub-meter hyperspectral and thermal satellite capability.
The startup’s first satellite, EARTH-1, will create the first global encyclopedia of Earth’s material composition, imaging the entire globe with more than 500 times the information density of existing sensors. Matter’s sensors redefine remote sensing with unprecedented precision. Unlike traditional hyperspectral technology, which often falls short of user needs for detail and material differentiation, Matter captures composition, temperature, and structure with a new standard of quality. Traditional systems can’t deliver the resolution and quality needed for actionable data, but Matter provides images that are orders of magnitude more information dense than hyperspectral systems – with science-grade quality and sub-meter resolution. Matter’s data accelerates geospatial computer vision, unlocking mass adoption of Earth observation and enabling powerful predictive capabilities and resilience.
EARTH-1 will be Matter’s first satellite and provide the world’s first sub-meter hyperspectral and thermal imaging capability. Matter will soon announce EARTH-1’s launch date. EARTH-1 will map and monitor Earth’s materials in real time, from mineral composition and vegetation health to atmospheric conditions. With this satellite, Matter is building the first global encyclopedia of Earth’s material composition – capturing the most detailed, multi-dimensional data across the planet.
Airloom Energy Announces $13.75M Financing to Accelerate Development of Pilot in Wyoming
Airloom Energy, the company unlocking the next generation and full potential of wind power, has secured $7.5 million in financing led by Lowercarbon Capital with participation from Breakthrough Energy Ventures, WYVC, Crosscut Ventures, WovenEarth Ventures, Adiuvans, and the Kutnick Family Office to support its vision of revolutionizing wind energy generation. The company also secured $5 million in Energy Matching Funds from the State of Wyoming and a $1.25M non-dilutive contract from the U.S. Department of Defense.
The new funding will support the development of a pilot in Wyoming to prove out power production and system efficiency, while demonstrating that Airloom can build wind for one-third the cost of conventional horizontal-axis turbines. The company will break ground on the project in the summer of 2025.
Just as Horizontal-Axis Wind Turbines (HAWTs) continue to grow in size and complexity, continued cost reductions are hindered by interest rates and supply chain issues. Airloom takes a fundamentally different approach with its simple, mass-manufacturable design that enables higher energy density and a smaller visual footprint without the massive infrastructure that conventional turbines require.
Lilac Solutions Announces $145 Million Series C to Scale Lithium Supply for the Electric Vehicle Era
