Alfa Laval is part of the next phase of development for a sustainable energy storage solution

Alfa Laval – a world leader in heat transfer, centrifugal separation and fluid handling – is part owner in the technology company Malta Inc. which is developing a completely new energy storage solution that will facilitate the shift towards renewable energy. Apart from being part owner, Alfa Laval is also responsible for collaborating with Malta on development of the innovative heat exchanger which is a critical component of the technical solution. Malta Inc. has now announced it has raised $50M in a Series B round of funding, which marks an important milestone towards the first full scale plant.

Shifting towards renewable energy sources is one way to reduce CO2 emissions and create a more sustainable energy supply. The challenge to replacing fossil fuels with renewables is the intermittency, as the power is not always produced when the demand is the highest, and the production is dependent on the sun shining and wind blowing. The solution to this challenge of intermittency is energy storage.

Alfa Laval’s innovative heat transfer technology is a critical component of the electro-thermal system which can store energy from any source (i.e. wind, sun etc) in any location. The system can store energy for up to several days, but early systems will focus on the near-term applications for 10-12 hours durations. The solution has the potential to dramatically improve power grid stability and resilience and has been in development since 2018. Malta Inc. has now raised $50M in a Series B round of funding with participation from new investors Proman and Dustin Moskovitz as well as existing investors Alfa Laval and Breakthrough Energy Ventures, to take the next step towards the first full scale plant, which is expected to be operating in the 2024-2025 timeframe.

“We believe that thermal storage will play an important role in the energy transition. After working with the Malta team for the past two years on novel heat exchanger design and development, we remain excited about this solution and the potential impact it can have on climate change” says Susanne Pahlén Åklundh, President of Alfa Laval’s Energy Division, and continues; “With collaborations like this we can reach further, expand the technical borders and create more sustainable solutions for the future.”

“Our goal continues to be to create a scalable storage solution that will accelerate the expansion of renewable energy while improving grid stability and resilience,” says Ramya Swaminathan, CEO of Malta Inc. “Alfa Laval has been a terrific partner to Malta from the founding of the company in 2018 and we look forward to continuing the great work that will help bring this solution to market.”
