The triangle of trust in the age of energy expansion | Critical Mass EP. 11

What happens when the world needs dramatically more electricity, but the minerals, infrastructure, and supply chains behind it cannot expand fast enough?In this episode, Peter Bryant, Board Chair of Clareo and Co-founder and Board Chair of the Development Partner Institute, explores what he calls the “age of energy expansion”, a period shaped by AI, data centres, electrification, industrial growth, and rising global power demand.The conversation examines the physical constraints behind that expansion, from looming copper shortages and long mine-development timelines to China’s influence over mineral processing and the strategic choke points embedded across global supply chains.But the discussion goes beyond infrastructure and commodities. Peter introduces his “Triangle of Trust” framework, arguing that governments, companies, and communities need shared incentives, meaningful participation, and a greater stake in resource development.As energy demand accelerates, the episode explores why the next phase of expansion will depend not only on technology and capital, but also on trust, legitimacy, and the ability to build projects that communities are willing to support."🎙️ LISTEN 👇Apple: https://podcasts.apple.com/us/podcast/critical-mass/id1874299043Spotify: https://open.spotify.com/show/0hROVvv9BoJnzsYZVPpKVTWebsite:All Socials: https://linktr.ee/criticalmassio #nuclearenergy #cleanenergy #renewableenergy #energycrisis #climatechange

Grid Electrification: The Scale Problem Nobody's Talking About | Critical Mass Episode 10

Can the world electrify its way to net zero? And what will power the parts of the economy that electricity cannot reach?In this episode, we sit down with Gerben Hieminga, Senior Energy Economist at ING Research, to examine how electrification could reshape the global energy system.In a net-zero scenario, electricity’s share of energy use in developed economies could rise from around 20% today to between 50% and 70% by 2050. Renewables and batteries are expected to provide much of that power, but the transition is creating new economic and infrastructure challenges.We discuss Europe’s energy paradox, where gas-fired power plants represent a relatively small share of generation but frequently determine electricity prices. Gerben also explains the emerging “fixed cost doom loop”: grids require major investment, while energy efficiency and rooftop solar can reduce demand from the network, pushing costs higher for those who remain connected.We explore the role of nuclear energy, including why factory-produced SMRs could help electrify high-temperature industrial processes, and why data centers and big technology companies may become important drivers of their development.For the parts of the economy that cannot easily be electrified, the discussion turns to green molecules, hydrogen, sustainable carbon sources, and the possibility of a future methanol economy for sectors such as shipping and aviation.As electricity becomes the foundation of the energy transition, this episode explores how grids, renewables, nuclear technologies, and green fuels will need to work together and why electrification alone will not be enough."

How To Manufacture nuclear energy at scale

Can nuclear energy scale by building reactors more like products than megaprojects?In this episode, we sit down with James Walker, CEO at Nano Nuclear Energy, to discuss the company’s vision for advanced nuclear energy and the role microreactors could play in meeting rising demand for reliable power.As data centers, military bases, industrial sites, and remote communities look for alternatives to conventional energy sources, Nano Nuclear Energy is developing modular reactor systems designed to be transported by road and assembled on site. We explore how this approach could reduce construction timelines, limit cost overruns, and create economies of scale through repeatable manufacturing rather than ever-larger individual plants.The conversation also examines the wider challenges facing advanced nuclear deployment, including licensing, nuclear fuel availability, and decades of underinvestment in enrichment and conversion infrastructure. Nano Nuclear Energy’s broader strategy now extends beyond reactors into transportation and the fuel supply chain.Looking toward 2030, the company plans to develop and license its first full-scale commercial microreactor at the University of Illinois. This episode explores what it will take to move from a first deployment to hundreds of systems serving data centers, military installations, urban locations, and remote communities."

Beyond the Reactor - The waste, risk, and opportunity

Can nuclear energy scale without solving the back end of the fuel cycle?In this episode, we sit down with Brett Rampal, nuclear energy expert and adviser, to examine one of the most important but often under-discussed parts of the nuclear sector: used fuel management.As nuclear energy gains renewed momentum in the US and globally, driven by reliability, energy security, AI, data centers, and industrial demand, the conversation increasingly turns to the full nuclear value chain, not just reactors, uranium supply, or new technologies, but what happens after fuel is used.We discuss why a credible used fuel strategy is critical to the sector’s next phase of growth, from addressing a long-standing federal commitment to unlocking trust, political support, and public confidence. Brett shares the challenges around the Nuclear Waste Fund, the legacy of Yucca Mountain, and how the spent fuel issue could be reframed from a political liability into an economic development opportunity.The conversation also looks at how innovation campuses, domestic fuel cycle capabilities, and long-term infrastructure planning could help strengthen the entire nuclear ecosystem. As demand for reliable power rises, this episode explores why solving the back end of the fuel cycle may be essential to nuclear energy’s future.

The Fatal Trifecta | Critical Mass Episode 7

Can electricity markets built for efficiency deliver the redundancy required for national resilience? In this episode, we sit down with Meredith Anguin, author of Shorting the Grid, to examine the growing vulnerabilities within modern electricity systems. We discuss why power should be understood not as a conventional consumer good, but as essential infrastructure that requires long-term planning, redundancy, and clear accountability. We explore Meredith’s concept of the “fatal trifecta”: over-reliance on intermittent renewables, dependence on just-in-time gas delivery, and growing reliance on grid imports. Together, these factors can weaken system resilience and increase the risk of blackouts when demand spikes, fuel supply tightens, or weather-dependent generation underperforms. The conversation also looks at the accountability gap in deregulated energy markets, where short-term competition can discourage investment in the infrastructure needed to maintain reliable power. From the role of nuclear energy as stable base load generation to the importance of domestic uranium enrichment capacity for energy security, we examine what it would take to rebuild reliability into the system."

Cyclical to Structural | Critical Mass Episode 6

Is a once-opaque commodity market becoming a fully-fledged financial asset class?In this episode, we sit down with Crispin Clarke, Strategic Advisor at Curzon Uranium and founder of DLT Advisory, to explore the structural shifts reshaping nuclear fuel markets. We discuss how new mechanics and investment vehicles are bringing greater liquidity, transparency, and institutional participation to a market that has historically been difficult to access.We examine why rising electricity demand, energy security concerns, and the acceleration of AI are creating powerful tailwinds for nuclear energy. From government policies aimed at expanding nuclear capacity to the realities of mine development timelines and supply constraints, we explore the forces driving a shift from cyclical commodity dynamics to a more structural investment theme.Disclaimer: The views and opinions expressed in this episode are those of the participants and do not constitute financial, investment, or legal advice.
