Moonwatt Raises $8.3M to Enhance Solar Energy Reliability with Innovative Sodium-Ion Storage Technology

The urgency to decarbonize our economies through electrification and clean energy is driving significant advancements in battery technologies. These innovations play a crucial role in facilitating the green transition by addressing the variability associated with renewable energy sources such as solar power. As solar energy installations continue to proliferate, the need for effective energy storage solutions becomes more critical.

The Importance of Energy Storage in Solar Power

While renewable energy sources are cleaner than fossil fuels, their output can be inconsistent. For instance, solar power generation halts once the sun sets, which presents a challenge for energy management. One effective solution is to store excess energy generated during peak sunlight hours for use during periods of higher demand.

Introducing Moonwatt: A Game-Changer in Energy Storage

Founded in September 2022 in the Netherlands, Moonwatt is a clean tech startup that focuses on developing a battery-based energy storage system optimized for solar power plants. The team has created specialized battery enclosures, inverter power electronics for grid connectivity, and software to effectively manage the storage system.

• Revenue Generation: Moonwatt’s system enables solar plants to increase their revenue by selling more energy at favorable prices.
• Cost Efficiency: The design reduces costs by sharing electrical infrastructure among multiple plants.

Targeted at solar plants generating several hundred kilowatts, Moonwatt aims to enhance their operational efficiency significantly.

Innovative Battery Technology: Sodium-Ion Cells

Moonwatt utilizes sodium-ion battery technology, which offers a cost-effective and sustainable alternative to traditional lithium-ion batteries. This choice helps lower production costs and enhances the scalability of energy storage solutions.

Although sodium-ion batteries may present size and weight challenges compared to lithium-ion, they are proving advantageous for stationary installations where space is less constrained.

Maximizing Solar Energy Output

According to co-founder and chief commercial officer Valentin Rota, Moonwatt’s energy storage system can increase the capacity factor of solar plants up to 80%. This improvement can potentially double the internal rate of return (IRR) for participating plants.

Rota explains, “In AAA-rated countries, typical photovoltaic assets yield returns between 8% to 12%, and our technology can elevate that to around 20%.”

Experienced Founders with a Vision

The founders of Moonwatt, including CEO Zukui Hu and CTO Guillaume Mancini, have a rich background in battery technology, having previously worked for Tesla and other industry leaders. Their experience spans various projects, including off-grid solar storage solutions.

Rota emphasizes the unique opportunity Moonwatt has to create a dedicated solar storage product, stating, “We realized that solar storage is the backbone of the future power grid, but there hasn’t been a product specifically designed for it.”

Funding and Future Plans

Moonwatt recently secured €8 million (approximately $8.3 million) in seed funding to accelerate the development of its storage technology. The startup plans to launch a pilot installation in Europe next year, with commercial deployments anticipated by 2027.

This funding round was co-led by Daphni and LEA Partners, with contributions from Founders Future, AFI Ventures, and Kima Ventures, among others.

Industry Impact and Ambitions

Paul Bazin, Partner at Daphni, commends Moonwatt’s innovative approach, stating it addresses a critical need for improved energy storage solutions as renewable power continues to expand. Rota expresses the ambition to be a significant player in the energy sector, focusing on cost competitiveness and scalability.

“Solar energy is becoming increasingly cost-effective and ubiquitous, with installations in over 120 countries annually,” Rota adds. By optimizing solar energy with dedicated storage solutions, Moonwatt aims to streamline energy distribution and enhance overall grid efficiency.

Conclusion

Moonwatt is positioning itself at the forefront of the energy storage revolution by focusing on solar power. With innovative sodium-ion technology and strategic funding, the startup is set to transform how solar energy is harnessed and utilized, paving the way for a more sustainable energy future.
