Simon Todd is back with Michael Barnard for part 2/2, and this time he’s drilling deeper—both literally and figuratively. In this second round, the Managing Director of Causeway Energies walks us through the hard tech and hard truths of geothermal energy, especially as it applies to the UK and Ireland. What emerges is a grounded, brutally realistic look at where geothermal works, where it doesn’t, and how to separate serious solutions from science fiction. We kick off with the cross-pollination of oil and gas tech into geothermal—rotary PDC bits, custom drilling muds, and all the bruised geology that comes with punching into granite. The oil patch may be sunsetting, but its tools are still getting a second act. Todd highlights how firms like Fervo are making surgical improvements to geothermal drilling by leveraging fracking's dirty tricks for clean heat, aiming to stimulate natural fractures in hot granite. It's technically elegant, but there’s a catch: the economics are still brutal. EGS systems might sound great on paper, but $150–$250 per megawatt-hour isn’t going to win against wind or solar anytime soon. Todd doesn’t sugarcoat it. The question isn’t if Fervo’s system works —it’s whether it can keep working at nameplate for 25 years straight. He then turns to the UK and Ireland's own geothermal potential. Unlike the flashy volcanic zones of the western U.S. or Iceland, we’re working with Hot Sedimentary Aquifers and radiogenic granites. The geology is less forgiving, but far from useless. Causeway’s bet is on moderate-depth wells—500 to 1,500 meters—which fall into what Todd calls the "Goldilocks zone": hot enough to matter, shallow enough to stay affordable. And this is where Todd really breaks from the crowd . Forget chasing deep geothermal megaprojects with 5 km drill strings and power plant dreams. Causeway Energies has pivoted to something far more practical: industrial heat. About half of emissions are tied to heating, most of it well below 100°C. Modern high-temperature heat pumps—some hitting 150°C—make pairing geothermal with industrial facilities like breweries and hospitals an obvious win. The kicker? These systems offer round-trip efficiencies that embarrass hydrogen and electrify sectors gas can’t reach. One technology worth highlighting here is the Standing Column Well—basically a turbocharged hybrid of open and closed-loop systems that’s 3 to 5 times more thermally potent than your average ground loop. It thrives in fractured aquifers that aren’t fit for drinking water, dodging some of the regulatory red tape. And with a century’s worth of oil and gas borehole data lying around, Causeway has a treasure map to the best locations. Simon Todd isn't pitching geothermal as a silver bullet. He’s carving out a niche: targeted, replicable, cost-effective solutions for decarbonizing industrial heat. It’s not glamorous. It’s not headline-grabbing. But it works . And in the climate transition, that might just be the most disruptive idea of all. Follow the podcast to hear more from the people actually building the energy future, not just imagining it…

In this eye-opening episode (part 1/2), Host Michael Barnard invites Simon Todd , Managing Director of Causeway Energies and a man whose geological expertise spans from the chalk beds of Northern Ireland to the drilling decks of BP. Simon joins the podcast to drag geothermal energy out of its misunderstood niche and into the spotlight it deserves. Simon, who spent 25 years at BP before pivoting hard into the future, lays out a vision for geothermal that’s far more than volcanic spas and Icelandic outliers. He starts by grounding us (literally) in the Earth’s temperature dynamics: from a molten 6,000°C core to the relatively tame gradients of continental crust. We learn that geothermal isn’t just a matter of poking around tectonic hotspots. With modern drilling and clever thermal engineering, you can tap heat just about anywhere—even in the soggy, non-volcanic soils of the UK and Ireland. He gets into the mechanics too, explaining how ground source heat pumps use the shallow earth—those top 10–15 meters that swing with the seasons—to store and retrieve heat. He unpacks the performance metric du jour, the Coefficient of Performance (COP), and shows how deeper wells (500 to 700 meters) vastly outperform air-source systems. The returns? In some projects, a sub-3-year payback. That’s not a climate virtue signal—that’s a boardroom greenlight. But Simon doesn't stop at closed-loop systems. He dives into the real geothermal opportunity hiding beneath our feet: open-loop aquifer systems. These draw warm water from permeable rock formations—‘rock sponges,’ as he puts it—offering faster heat transfer than passive conduction. And yet, while ATES systems thrive across the Netherlands and Belgium, they’re barely used in the UK or Ireland. Why? Bureaucratic inertia, unfamiliarity, and maybe just a lack of storytelling. With directional drilling tech now able to reach aquifers from a single pad, and real-time data steering drill heads with pinpoint accuracy, Simon argues we have the tools and the data. What’s missing is awareness—and maybe a bit of ambition. This episode is a geothermal masterclass from someone who’s lived both the legacy fossil past and the clean energy future. If you're still thinking geothermal is just for hot springs and sci-fi, Simon Todd is here to prove otherwise—with numbers, with tech, and with real-world results. Follow the show for more episodes like this one, where energy myths get debunked, and the future gets explained.…

Michael Barnard welcomes back Elisabet Liljeblad, the sustainability and energy lead with Stena Teknik, for the second half of their conversation on redefining energy Tech. They start by discussing the efficiency of electric drive trains in shipping and compare it to reciprocating engines. Methanol is explored as a shipping fuel with lower emissions and cleaner burning properties. Ammonia is discussed as a potential transportation fuel but poses toxicity and safety challenges. Hydrogen is also considered, highlighting its clean combustion but issues with storage, cost, and low conversion efficiency. Equinor abandoned their cryogenic hydrogen bunkering due to high costs. There are doubts about the viability of hydrogen-powered ships, as batteries tend to be cheaper. However, some companies like Swedish Goslin Ferries are still pursuing hydrogen solutions. The challenges of producing and storing liquid hydrogen make it less energy-dense than diesel or ammonia. A potential solution for ships is a battery-biofuel hybrid model that gradually replaces diesel with biodiesel over time. Electrification using containerized batteries in ports and on ships is another promising option, especially for roll-on/roll-off vessels. Collaboration between the shipping and rail industries could allow shared use of battery containers for more efficient electrification efforts. Additionally, bunkering electrons instead of conventional fuel is being explored as an alternative for reducing emissions from cruise ships in Norwegian fjords by 2026. Liljeblad discusses the concept of electron bunkering vessels, which are ships with batteries that provide energy to other ships. She emphasizes the need for a total rethink in how we value companies and use resources to address environmental issues. Liljeblad closes by highlighting the importance of individual responsibility and making sustainable choices as consumers. She believes there is great potential for electrifying container shipping and using existing solutions to transition towards a more sustainable future.…

Michael Barnard welcomes Elisabet Liljeblad, PhD, the sustainability and energy lead with Stena Teknik, to discuss decarbonization in the maritime industry. Elisabet shares her diverse background including studying the magnetosphere of Mercury and a stint in Afghanistan keeping the peace, and how she ended up in shipping. Full transcript . They explore the scale of the maritime industry and its challenge of decarbonization due to its size, variety of vessels, and dependency on fossil fuels. Shipping constitutes a significant amount of emissions globally. The conversation touches upon different types of ships within Stena's business units, including drilling, bulk transportation, passenger ferries, technical services, and their varying operational characteristics. They highlight the need for different fuel logistics as ships transition away from fossil fuels towards electrification or alternative fuels like ammonia, methanol, hydrogen or biodiesel blends. The challenges faced by ports in accommodating these diverse refueling options are also discussed along with onboard carbon capture as a potential solution.The potential for electrification in marine shipping is significant, with projections suggesting that 40% of container ships can be electrified within this decade. Methanol is another opportunity for shipping fuel, and Stena has converted a ropax vessel to run on both diesel and methanol. Methanol has half the energy density of fossil diesel but doesn't evaporate at room temperature. It's relatively easy to store and handle but requires separate tanks from other fuels due to its characteristics. Biodiesel, particularly hydrotreated vegetable oil (HVO), burns cleaner than fossil fuels with lower emissions of pollutants like sulfur oxide (SOx) and nitrogen oxide (NOx). HVO is considered a high-quality biofuel that emits fewer harmful substances and doesn't require special considerations like microbial growth.However, as green hydrogen becomes more prevalent in HVO production processes, it may become more expensive compared to other biofuels that don't rely on green hydrogen. There's no magic bullet solution for decarbonizing marine shipping; it requires a mix of solutions depending on the type of ship and route involved. They discuss the difference between N20 and NO2, both created by burning anything in our atmosphere, with a focus on their effects on human beings and the environment. Ultimately, the goal is to move away from burning fuels and transition to electric engines as much as possible for more efficient energy utilization.…

In the second part of his conversation with David Cebon, head of the Centre for Sustainable Road Freight and professor of mechanical engineering at Cambridge, Michael Barnard discusses the challenges of integrating logistics activity and energy activity in decarbonization efforts. The need for bigger batteries in trucks is temporary and will eventually become a matter of economics. Transcript . However, the challenge lies in charging infrastructure at warehouses, where vehicle turnarounds require tens of megawatts to charge during half-hour periods. This distributed problem requires warehouse owners to spend millions on electricity grid connections to charge third-party vehicles. Overhead contact lines are seen as an important solution because they eliminate the need for big fat grid connections and can be built out along heavily trafficked roads through a single contract rather than thousands of distributed warehouses needing upgrades simultaneously worldwide. Modular electric vehicle platforms with battery swapping capabilities could help cover most logistics solutions globally by allowing OEMs to make slightly different configurations depending on country needs while reducing costs compared to adding megawatt hours or hydrogen fuel cells. Finally, there is a debunked piece of folklore that heavier electric vehicles cause more road damage when truck weight laws vary widely among U.S states with Michigan having double Class 8 tractor semi-trailer weights allowed while civil engineers use something called "the fourth power law" based on outdated constructions from late 1950s AASHO Road Test results which saw most damage occur due to weather conditions rather than vehicle loading factors.Cebon discusses the fourth power law and its impact on road damaging potential of axles, which has been debunked. They also talk about the history of lane width and how it affects driver behavior. Additionally, Cebon shares his opinion on hydrogen fuel cell trucks for heavy ground vehicles and highlights their high cost compared to electric trucks due to a steep learning curve for hydrogen technology in small quantities.…
