Span: Accelerating rapid adoption of renewable energy solutions through intuitive home integration and interface.

Span was created to bring the innovations of tomorrow into the homes of today. They rebooted and overhauled the 100-year-old electrical panel and have developed an easy-to-use interface system through which renewable energy sources can be readily interfaced and integrated into a home. Reduce cost, improve sustainability, and build a smart home – controlled at the touch of a button – all through Span.

"At Span we are re-architecting the home electrical panel to be the central hub for monitoring and managing all energy resources and loads in the home. The Span panel is engineered to give homeowners very high levels of insight and control into all aspects of their home energy usage. TDK is a key partner for us in delivering state-of-the-art products and groundbreaking services to customers. We are glad to have TDK Ventures onboard, journeying with us step-by-step and adding value along the way."

Divirod’s cost-effective and scalable water network solution brings accessible, hyperlocal, and high-quality data in real-time.
GenCell has developed an off-the-grid or back-up power solution that runs completely on hydrogen or ammonia fuel and can operate and tolerate across the gambit of environmental conditions.
Ascend Elements has created a novel closed loop recycling process, recovering high value battery components for reuse without the need to reprocess raw materials.
Verdagy is innovating water- electrolysis technology for the large-scale production of green hydrogen.
AMB’s innovative “dry” process to print Li-ion battery electrodes can reduce energy consumption of a battery plant by 50%, save 40% in capital expenditure and enable potentially higher energy, faster charging, and lower cost batteries.
pH7 Technologies developed a proprietary metal-extraction process utilizing non-toxic organic and inorganic chemistry, as well as electrochemistry to drive extraction of metals and key minerals from ores, concentrates, and end-of-life materials.
Type One Energy is tackling the technical challenges that have kept fusion from becoming a practical reality with the latest advances in additive manufacturing and high-temperature superconductor magnets.
Novalith’s technology solutions capture and leverage carbon dioxide (CO2) from the atmosphere to isolate and extract higher quality – battery grade – lithium from resource deposits, with no harmful by-products. Their process uses less water, smaller infrastructure, and is a lower cost than current industry standards.
Peak Energy has developed an innovative sodium-ion-based energy-storage solution that is expected to be more cost-effective, durable, and easier to mass produce domestically.
Exponent believes EVs have completed the 0 to 1 shift of driving better than conventional vehicles. However, for the industry to exponentially scale from 1 to 100, the underlying energy problem needs to be simplified.
At INERATEC, they are pioneering the post-fossil fuel age by saying goodbye to crude oil and saying hello to a planet powered by synthetic fuel. Made in their Power-to-X plants, their e-Fuels and e-Chemicals can change the transportation and chemical industries as we know them.
Amperesand’s infrastructure solutions, powered by novel solid-state transformer (SST) technology, enable efficient, intelligent, and resilient electrification on a global scale.
