Masen and Cleanergy step up their joint quest for low cost solar energy storage

Storage of renewable energy for on-demand distribution of cost competitive and clean electricity is key for fossil-free power generation. Swedish solar technology company, Cleanergy and Masen (Moroccan Agency for Sustainable Energy) have an ongoing collaboration to address this challenge. The Masen-Cleanergy collaboration is now intensifying through new joint development agreement.

The collaboration between Cleanergy and Masen in Concentrated Solar Power (CSP) and Thermal Energy Storage (TES) solutions is taking a big step towards commercialization. Through the agreement, Masen will take a place in Cleanergy's board of directors and fund a substantial part of the company's Thermal Energy Storage R&D, industrialisation and business development.

Masen adds valuable knowledge of the solar market to Cleanergy's strategy, but also grants access to a vast network of established partners and stakeholders in the CSP industry, as well as to new suppliers for local sourcing and production. Masen's R&D Platform in Ouarzazate, one of the biggest worldwide, will help test the solutions in optimal solar conditions.

Masen's team of engineers will contribute to the evaluation and design of the TES system, land and grid connection for complete system testing in Morocco, as well as introduction and demonstration for prospective customers on the African continent.

Masen has a strong R&D strategy, which actively evaluates and promotes disruptive and competitive technologies. The co-development of innovative TES systems is an important step forward for CSP technologies. Cleanergy's storage demonstrator will be installed on our R&D Platform in Ouarzazate, which will help accelerate its commercialization.”, says Mr Bakkoury, the President of Masen.

“Collaborating with Masen has been very positive for our development and having them onboard means we can now work even closer together. With their incomparable experience of renewable energy and solar power we get access to a network of knowledge, resources and prospective customers. Masen will also be a key partner in verifying the technology before launching to the market”, says Jonas Eklind, CEO of Cleanergy.

A demonstrator of Cleanergy's Thermal Energy Storage system will be presented in June 2018.
