Nyobolt's ultra-fast charging batteries, Antora's giant thermal battery, and Trump's attempted coal revival

Recorded 7th June. In this episode, we catch up after Charlotte’s set the record for the Fastest Known Time running the Camino de Santiago, and Lucy being elected as a local councillor.We then dive into four major energy stories spanning cutting-edge battery technologies, industrial decarbonisation, coal policy, and mine safety.Nyobolt's $60M Series C: The Future of Ultra-Fast ChargingNyobolt has become the latest UK battery unicorn after raising a $60 million Series C round. Charlotte explores why the company is taking a different approach from most battery developers by prioritising charging speed and power delivery rather than simply increasing energy density.Why conventional lithium-ion batteries struggle with ultra-fast chargingHow niobium-based anode materials allow lithium ions to move more rapidly through the batteryThe trade-off between energy density and power densityWhy fast charging matters more for robots, mining equipment, defence systems, and industrial automation than passenger EVsHow higher utilisation can create significant economic value for robotic and autonomous systemsThe growing opportunity for high-power batteries in AI infrastructure and data centresAntora Energy's 5 GWh Thermal Battery ProjectAntora Energy has deployed one of the world's largest energy storage projects, using renewable electricity to provide industrial heat rather than electricity. Charlotte discusses why industrial heat represents one of the biggest decarbonisation challenges globally and how thermal batteries could help solve it.How Antora stores electricity as heat in solid carbon blocks at temperatures above 2,000°CWhy industrial facilities need heat rather than electronsHow thermal storage enables renewable energy to provide reliable 24/7 industrial steam and process heatThe role of thermal batteries in sectors including steel, cement, chemicals, food processing, and pulp and paperHow Antora's radiative heat transfer system differs from conventional thermal storage technologiesThe potential future use of thermophotovoltaics to convert stored heat back into electricityWhy ethanol production is proving to be an attractive first commercial marketTrump's $700 Million Coal PushThe Trump administration has announced a new package of support for the US coal industry. Lucy examines the rationale behind the policy, the economics of coal in modern electricity markets, and whether coal still has a role to play in supporting grid reliability.New funding for coal plant upgrades, export infrastructure, and proposed new coal plantsThe difference between coal as a reliability resource and coal as baseload generationWhether preserving existing coal plants makes economic senseHow coal compares with renewables, batteries, gas, and other firm power resourcesWhether AI-driven electricity demand changes the case for coal, as data-centre developers favour nuclear, geothermal, renewables, and storage over new coal generationChina's Deadliest Coal Mine Accident Since 2009We conclude with a discussion of a tragic coal mine accident in China that claimed 82 lives and what it reveals about the broader costs of fossil-fuel dependence.The human cost of coal mining and industrial accidentsHow safety regulations affect the economics of coal productionWhether major incidents accelerate transitions away from coalThe balance between energy security, affordability, and worker safety
