Canadian investor Brookfield has agreed to invest $1bn in Avaada Ventures to support green ammonia plans and scale up renewable energy, in what would be the largest investment by a clean energy company in one go. Vineet Mittal, founder of the Avaada group, signed a formal agreement with Brookfield, with the first tranche of $400m already disbursed. The remaining $600m will be disbursed based on performance-linked milestones.
