ICM München
Room 4

Long-duration energy storage (LDES) is undoubtedly a key enabler for achieving net-zero. However, despite a wide range of technology providers claiming cost competitiveness and other advantages over lithium-ion batteries, the latter continue to dominate new deployments in Europe and elsewhere. So what's holding LDES back? What is needed to enable more widespread adoption? And when will the age of LDES finally arrive?

In this panel, experts will provide an assessment of the suitability of LDES for today's market, the barriers that exist and the requirements and likely timeline for LDES to finally become mainstream.

Jan Andersson, Sumitomo SHi FW

Director, Global Market Development


Jan Andersson believes in data transparency and collaboration. He takes the position that people are smart and capable of acting on all available information. Bringing all relevant data to the decision table is, therefore, the means by which Jan feels he can make a difference. As Sumitomo SHI FW's Director Global Market Development, Jan has worked extensively in the European, Indian and Australian markets to facilitate the change to more sustainable, decarbonised power systems. Jan is a problem-solver and a down-to-earth idea generator who outlines the big picture before jumping to conclusions. With his broad knowledge in energy technologies, e.g. energy storage, Power systems and modelling, as well as his understanding of energy trading and finance, Jan brings clarity on how things are connected. He believes that the energy transition is a source for new business opportunities for the energy sector, and that by challenging conventional thinking and exchanging data and experience, the industry has real development potential. It is not surprising, therefore, that increasing collaboration between individuals, companies, and countries, is what keeps Jan on the move. He feels, however, that there is room for improvement in the sharing of expertise, experience and facts. For example, he explains that there is no single silver bullet to manage the energy transition, rather we need to leverage the benefits of different technologies in order to be successful.
