Concept note
An intensive concept note sets out the thermal battery for heavy industry.
Our journey
From vision to validation.
In under two years we've gone from a concept note to a lab-validated prototype at TRL 4. Along the way: a university feasibility study, Africa's leading enterprise development programmes, and appointments on the global climate stage.
