Enervenue Secures $100M for Nickel-Hydrogen Battery Innovation

The Need for Grid-Scale Energy Storage and EnerVenue's Solution

The increasing integration of renewable energy sources, such as solar and wind, necessitates substantial battery storage capacity to address the intermittent nature of their power generation. While lithium-ion batteries are prevalent in consumer electronics and electric vehicles, EnerVenue, a battery startup, asserts it has developed a groundbreaking technology poised to transform stationary energy storage.

Nickel-Hydrogen Technology: A Proven Concept Reimagined

The core of EnerVenue’s innovation lies in nickel-hydrogen battery technology. This isn’t a novel concept; in fact, it has been reliably utilized for decades in aerospace applications, powering critical systems on satellites, the International Space Station, and even the Hubble Telescope. Previously, the high costs associated with nickel-hydrogen batteries hindered their widespread adoption for terrestrial uses.

However, a breakthrough by Stanford University professor Yi Cui, now EnerVenue’s chairman, has enabled the adaptation of materials and a significant reduction in production expenses.

Advantages of Nickel-Hydrogen Over Lithium-Ion

EnerVenue highlights several key advantages of nickel-hydrogen batteries compared to lithium-ion alternatives:

• Exceptional temperature tolerance, eliminating the need for complex thermal management systems.
• Minimal maintenance requirements, reducing operational costs.
• An extended lifespan, offering long-term reliability.

These benefits position nickel-hydrogen as a compelling option for grid-scale energy storage.

Significant Investment and Strategic Partnerships

The potential of EnerVenue’s technology has attracted substantial investment from industry leaders. A combined investment of $100 million in Series A funding was secured from Schlumberger, a major energy infrastructure company, and Saudi Aramco’s venture capital arm, alongside Stanford University. This follows a prior $12 million seed funding round.

The company intends to utilize these funds to expand its nickel-hydrogen battery production capabilities, including the construction of a Gigafactory within the U.S. Furthermore, a manufacturing and distribution agreement has been established with Schlumberger to serve international markets.

Cost Reduction and Technological Advancement

CEO Jorg Heinemann revealed that the company’s research, spearheaded by Professor Cui, has dramatically lowered the cost of nickel-hydrogen batteries. The price has been reduced from approximately $20,000 per kilowatt hour to a projected $100 per kilowatt hour, bringing it in line with current energy storage technologies.

A nickel-hydrogen battery functions as a hybrid between a traditional battery and a fuel cell. During charging, hydrogen is accumulated within a pressure vessel, and upon discharge, this hydrogen is reabsorbed into water, as explained by Heinemann.

EnerVenue’s innovation centers on the materials used. Unlike aerospace applications which utilize expensive platinum electrodes (accounting for up to 70% of the battery cost), EnerVenue has identified and implemented low-cost, readily available materials – the specific composition of which remains proprietary.

Performance and Future Development

EnerVenue’s batteries offer flexible charging and discharging capabilities, adapting to diverse customer needs. They can handle rapid 10-minute cycles or slower 10-20 hour cycles, with optimization focused on a two-hour charge and four- to eight-hour discharge profile. The batteries are also engineered for 30,000 cycles without significant performance degradation.

The ability to efficiently store excess renewable energy during periods of low demand and then dispatch it when needed is a key advantage. Heinemann emphasized the battery’s suitability for capitalizing on periods of near-free power.

Industry Shift and the Role of Oil and Gas

The funding round’s backing from Schlumberger and Saudi Aramco highlights a significant trend: the oil and gas industry’s substantial pivot towards renewable energy. Heinemann noted that the industry recognizes the inevitable shift towards a predominantly renewable energy mix – projected to reach 75% by mid-century – and is actively seeking new opportunities.

Applications and Scalability

While nickel-hydrogen batteries are unlikely to replace lithium-ion in portable devices like smartphones due to their size and weight (approximately the volume of a two-liter bottle), they are ideally suited for stationary energy storage.

EnerVenue is currently finalizing plans for a U.S.-based factory capable of producing up to one gigawatt-hour of batteries annually, with ambitions for further expansion. The company anticipates tooling costs per megawatt-hour to be just 20% of those associated with lithium-ion technology. Schlumberger will independently manufacture and distribute batteries in Europe and the Middle East under the partnership agreement.

A Proven Technology Ready for Deployment

Heinemann confidently stated that the technology is fully functional and ready for deployment. “We are not awaiting a technological breakthrough; there are no scientific hurdles remaining to validate our approach. We know it works.”
