About us

Energy Storage

The growing penetration of renewable energy has brought uncertainty and intermittence to the electricity landscape: the need for a buffer to stabilize such intermittency is becoming pressing. Energy storage is an emerging solution to address this issue, along with demand response, ancillary services re-design or grid reinforcement. While pumped hydro storage plants have been used for decades, many innovative technologies to store energy are coming to maturity, such as Compressed Air Energy Storage, batteries and flywheels.

Energy storage can also be understood from the thermal storage point of view. In a context of increasing energy costs, storing and recuperating waste heat–for, instance, industrial processes – will become increasing important for industrial and utility stakeholders.

Clean Horizon helps its clients identify deep trends as well as weak signals, which are key to their success, in a complex technological, regulatory and business environment.


Clean Horizon is always seeking applicants with both an entrepreneurial and intellectual frame of mind, interested in taking a key role in an emerging growth industry.

Deep understanding of technology, dedication to become an expert and to broaden one’s horizons will be key assets in applying with Clean Horizon! If you're interested, please send us an email at careers@cleanhorizon.com.


Clean Horizon organizes tailored training according to customers’ requirements (market data, business case on a application or a project, legislative and regulatory data, a specific type of storage technology, what are the market opportunities and the activities of other storage players in Europe, and at the global scale.

Michael obtained his engineer’s degree at Mines ParisTech in France and his Ph.D. at Stanford in the USA. He witnessed the booming of cleantech venture capital and entrepreneurship while an academic in the Silicon Valley, and then went on to become a management consultant at McKinsey in Paris. Since 2009, Michael has been believing that a high penetration of renewable energy can only be possible if a strong energy storage sector is formed. He thus founded Clean Horizon to provide technological, regulatory and business expert information to stakeholders of this emerging industry.
