From Complex Models to Climate Solutions: The Transition Zero Story
Send me a messageHello, Climate Champions! In today's episode of the Climate Confident Podcast I had the pleasure of hosting Matt Gray, the co-founder and CEO of Transition Zero, a trailblazer in energy systems modelling.In our conversation, Matt delved into the intricate world of energy systems modelling, a crucial tool for stakeholders and decision-makers in shaping our energy future. He emphasized Transition Zero's mission to democratise this complex tool, making it accessible, auditable, and reproducible. This, Matt believes, is vital for accelerating the transition to a sustainable energy future.We explored the significant challenges in moving towards net zero, particularly the technical and political barriers. Matt highlighted the crucial role of transmission investments in the energy grid and how these investments, or the lack thereof, influence our ability to harness low-cost renewable energies like wind and solar.Another key takeaway from our chat was the importance of data transparency in fostering global collaboration. Matt underlined how Transition Zero's commitment to open data and models aims to bridge the gap between pledges and actions in climate commitments, thereby enhancing global climate action.Matt's insights on the role of transmission in achieving net zero were particularly thought-provoking, revealing how strategic investments can save trillions while facilitating a faster shift to renewable energy sources.We wrapped up with Matt's thoughts on COP28 and his future plans for Transition Zero. For those keen to learn more about their groundbreaking work or get involved, check out the TransitionZero website.Check out the video version of this episode on YouTube.Tune in, get inspired, and let's continue to make strides towards a sustainable future together!

From Methane to Minerals: The Pioneering Path to Carbon-Negative Energy
Send me a messageWelcome to another enlightening episode of the Climate Confident Podcast. Today I have the pleasure of diving deep into the world of carbon-negative hydrogen with Arnaud Lager, the Founder and CEO of Decahydron.Arnaud brought to light some groundbreaking work his team is doing in Ra's al Khaimah, UAE. They're not just creating hydrogen; they're doing it in a way that actively reduces carbon emissions. The magic happens through a unique process where methane is cracked to produce hydrogen, coupled with capturing CO2 from local cement industries. But here's the clincher – this CO2 isn't just captured; it's transformed into carbonate minerals by being injected into ultramafic rocks, ensuring it's locked away permanently.We also explored the fascinating potential of natural hydrogen reserves in the region. Imagine, hydrogen bubbling up from the ground – it's not science fiction but a reality that could revolutionize our energy landscape. Decahydron's pursuit of this untapped resource could be a game-changer, offering a more sustainable and cost-effective hydrogen source.But it's not all about hydrogen. Arnaud and his team have set ambitious goals for CO2 sequestration, aiming to tackle gigatons of emissions. Their approach is pragmatic yet innovative, focusing first on high-concentration CO2 sources before venturing into more dilute areas like direct air capture.This episode is a must-listen for anyone interested in the cutting-edge of climate technology and sustainable energy. Arnaud's insights offer a glimpse into a future where energy production and environmental stewardship can go hand in hand.Stay tuned for more updates on Decahydron's progress and do check out their website for the latest news. Remember, tackling climate change requires a variety of approaches, and it's pioneers like Arnaud who are leading the charge.Btw, don't forget to check out the video version of this podcast at https://youtu.be/lJv5RZfzj1ISupport the showPodcast supportersI'd like to sincerely thank this podcast's amazing supporters: Jerry Sweeney Andreas Werner Stephen Carroll Roger Arnold And remember you too can Support the Podcast - it is really easy and hugely important as it will enable me to continue to create more excellent Climate Confident episodes like this one.ContactIf you have any comments/suggestions or questions for the podcast - get in touch via direct message on Twitter/LinkedIn.

Beyond Lithium: The Rise of Vanadium Flow Batteries in Renewable Energy
Send me a messageIn this episode of the Climate Confident podcast, I talked energy storage with Matt Harper, the Chief Commercial Officer at Invinity Energy Systems, who explained vanadium flow batteries—and their implications for renewable energy.We started with a 'Battery 101' comparing the familiar lithium-ion to vanadium flow batteries. Matt shared fascinating insights into the modular nature of these batteries, how they differ in their response to the degradation issues plaguing conventional batteries, and their non-flammability—a significant safety advantage.We discussed the role of vanadium flow batteries in supporting infrastructure rather than powering EVs, given their weight. But where they truly shine is in the realm of grid energy storage.Looking at the bigger picture, Matt highlighted the economic shifts towards longer-duration storage, driven by the ever-decreasing costs of solar and wind power. Our conversation touched upon the broader market dynamics and the critical role of energy storage in achieving a net-zero future.The episode closed with Matt's passionate perspective on the necessity of supportive industrial policies for renewable technologies, ensuring a robust and sustainable energy sector.Do not miss this enlightening conversation on 'Climate Confident,' where we continue to unravel the innovations steering us towards a cleaner, more resilient energy future.

Waste Not, Want Not: Ingenium's Blueprint for Sustainable Business
Send me a messageHey, Climate Confident listeners! 🎧 Today's episode was such an eye-opener! I sat down with Heather Johnson, the CEO of Ingenium, a company revolutionising the way we look at waste.We delved deep into how waste, especially hazardous waste, can be an untapped goldmine. Imagine your waste, not just as a discard but as a valuable resource to another company? Ingenium is doing just that! Matching waste producers with companies that need these very resources. Not only does this have cost-saving implications, but the environmental benefits are staggering. It’s the very epitome of sustainability.Heather shared how Ingenium has been making waves, particularly with large public companies, in turning waste into a repurposed asset. With California pushing businesses for waste reduction and sustainability becoming a worldwide focus, the scope of this industry is immense. 🌏But as Heather pointed out, challenges abound. With the rising waste, diminishing incineration facilities, and increasing regulations, there's a dire need for forward-thinkers and innovators. And that's where Ingenium steps in, aiming to be at the forefront of waste management for decades to come.One key takeaway? It's crucial to partner with a reputable waste management company. Heather highlighted the "cradle to grave" concept - you're responsible for your waste till the end. So ensuring it's in trustworthy hands is paramount.Want to delve deeper into Ingenium's groundbreaking approach to waste management?
