Anmay Dittman, Managing Director and Head of the Climate Finance Partnership at BlackRock: on Blended Finance, Emerging Markets & Redefining Risk in Climate Infrastructure | Season Nine, Episode Eight
Welcome to Season Nine of Conversations in Cleantech!
This season, we’re going behind the scenes of transition infrastructure - speaking with the investors shaping how, where and why climate capital flows. From decarbonisation and energy security to technology maturity and policy gaps, we’re unpacking what it really takes to fund the systems that underpin a net-zero future.
In this episode, our host Jenny Gladman is joined by co-host Isabella Rova to speak with Anmay Dittman, Managing Director and Head of the Climate Finance Partnership at Global Infrastructure Partners (GIP), part of BlackRock - a leader redefining what’s possible in blended climate finance.
At the helm of one of the fastest fundraises in BlackRock’s history, Anmay has mobilised over $700 million to accelerate renewable infrastructure in emerging markets - from Kenya’s landmark Lake Turkana wind farm to a growing pipeline of solar and storage investments across Africa and beyond.
In this conversation, they explore what it really takes to deploy climate capital where it matters most: how blended finance can de-risk high-impact projects, why local engagement is the key to lasting success, and where the next frontier of opportunity lies - from energy access to data centres powering the digital future.
Expect a candid deep-dive into innovation, inclusion and ambition, and how reimagining risk can unlock not just investment returns, but real-world resilience.
01:09 - Introduction to Anmay
03:08 - Can you tell us a bit about your story so far?
05:20 - What drew you into climate finance?
06:29 - Raising hundreds of millions in under a year during COVID is incredible - what made that possible, and who were the investors behind it?
09:50 - The Lake Turkana project stands out as one of Africa’s largest wind farms - what lessons did it teach you about managing risk and delivering community impact?
12:00 - Have you been there yourself?
13:00 - Emerging market investing comes with challenges like currency volatility - how do you approach FX risk in places where hedging isn’t affordable?
15:55 - Your pipeline shows a shift from wind toward solar - what’s driving that, and is storage becoming investable at scale?
17:55 - How do you identify the biggest opportunities in Africa’s mining decarbonization space, from both an impact and investment perspective?
19:29 - Can you share a personal moment or story that shows why this mission matters to you?
21:40 - If you could change one market condition tomorrow to accelerate private capital into emerging markets, what would it be?
23:50 - Looking five years ahead, what do you think will be the most exciting development in climate infrastructure across emerging markets?
25:20 - Who inspires you, whether peers or key figures, to keep pushing forward and doing what you do?

Brian Sheng, Co-founder & CEO at Aquaria, on Resilience & Reimagining Water Infrastructure | Season Eight, Episode Fourteen
Welcome to Season Eight of Conversations in Cleantech!
From inspiring stories and words of wisdom to conversations on overcoming obstacles and fostering innovation, you can expect to learn from the trailblazers who are navigating the complexities of change to build a cleaner, more sustainable future.
In this episode of Conversations in Cleantech, our host Olivia Morgan speaks with Brian Sheng, Co-founder and CEO of Aquaria - the startup turning air into water and rethinking what infrastructure can be.
Founded at the height of the pandemic, Aquaria’s story doesn’t follow the usual cleantech playbook. Back when most investors barely registered water as a climate issue, Brian and his co-founder, who also happens to be his brother, were building a hardware solution no one believed was possible, let alone scalable. Fast forward to today, and Aquaria is supplying water to 1,000 homes in the U.S., launching projects across the GCC, and proving that the future of water doesn’t have to come from the ground.
In this conversation, Brian shares what it took to get here: the challenges of building hardware in a remote world, the misalignment between capital and need, and why personal commitment can’t be outsourced. He also talks about what early-career professionals should look for when breaking into the sector - and why execution matters just as much as mission.
From personal tragedy to global impact, this is a story about clarity, resilience, and redefining what’s possible when you stick to the vision, even when the market doesn’t get it yet.
00:53 - Introduction to Brian
01:43 - Can you please tell us a bit about yourself and your story?
02:45 - Can you share the story behind founding Aquaria and how it represents driving change in the industry?
04:33 - Can you tell us more about Aquaria’s journey since its founding in 2021 and what your role has looked like along the way?
06:20 - What have been the most rewarding experiences since starting the company?
08:10 - How did you overcome the challenges, especially founding during COVID, and adapt to reach where you are today?
10:18 - What lessons would you share with those looking to shape a career in clean tech?
12:27 - What key changes and trends have you seen in the market over the past few months and years?
14:45 - How are you navigating market changes while continuing to meet the growing need for Aquaria’s work?
17:25 - How did you prove yourself to investors and the wider market, and navigate that challenge?
19:40 - What advice would you give to people or companies, especially non-traditional decarbonisation ones, navigating today’s challenging market?
24:30 - What’s one clean tech token of advice you’d offer for success in the field?
