On Their Path To Scale is a series that highlights technologies from across the Elemental Impact portfolio that are moving the needle on climate and community impact.
The Solution
Noon Energy’s breakthrough technology converts intermittent solar and wind power into firm, reliable electricity available 24/7, 365 days per year. The Noon battery system stores energy in a remarkably compact footprint, using the same abundant elements nature uses to store energy (as in photosynthesis), rather than relying on expensive metals like those found in conventional lithium-ion batteries.
With a storage capacity of 100+ hours, the Noon long-duration battery supports a resilient grid and independence from fossil fuels—a solution fit for hyperscale data centers, behind-the-meter commercial and industrial deployments, as well as remote communities and microgrids.
Impact in Community
Noon’s East Palo Alto deployment is located in a community facing disproportionate environmental burdens—where asthma rates are up to four times higher than neighboring cities. By pairing solar with multi-day storage, the project demonstrates how resilient, locally-sited clean energy can reduce air pollution and reliance on fossil generation, while strengthening community preparedness during grid outages.
Path To Scale
Earlier this year, Noon Energy announced an agreement with Meta to reserve up to 1 GW / 100 GWh of energy storage capacity for next-generation AI data center infrastructure. The 50 kW/10 MWh East Palo Alto deployment was critical to validating the technology, unlocking the agreement between the two companies. Looking forward, Noon Energy is targeting more than 40 MW (4 GWh is enough to power around 40,000 typical US homes) of additional deployments within three years, positioning long-duration storage as a foundation for 100% reliable renewables at scale.
Elemental’s Role
Elemental invested in Noon to deploy its first commercial-scale system in East Palo Alto, California—a 50 kW system with 10 MWh of storage capacity, paired with solar. The installation represents a large scale-up from Noon’s previous demonstration system and will validate system performance, durability, and the ability to meet product cost targets at field scale. The project is generating the operational data needed to demonstrate low-cost, multi-day storage capable of supporting critical infrastructure.
In addition to supporting the field demonstration, Elemental is working alongside Noon on fundraising preparation, project finance strategy, and operational readiness as the company prepares for its next phase of growth. Our team coached the company on policy power mapping and landscape assessment, helping clarify key regulatory stakeholders.
“Elemental’s support has helped bring our energy storage system to life for the first time in East Palo Alto, demonstrating our technology in a community-engaged setting while providing a critical proof point for hyperscalers looking to deploy our solution to decarbonize data centers. This experience has underscored for me the critical role supportive partners like Elemental can play as founders juggle technical execution with business, negotiation, and storytelling.” – Chris Graves, Co-Founder and CEO, Noon Energy
