Achieving net-zero carbon emissions is a massive challenge for every industry, but some have it harder than others. This week, Bloomberg Green senior reporter Akshat Rathi spoke with two Australian startups that are tackling carbon emissions in sectors whose carbon footprints are particularly intractable. Inspired by shark skin, MicroTau is creating a plastic film that makes airplanes more aerodynamic, reducing their fuel consumption. Novalith, meanwhile, is redesigning lithium battery manufacturing to make it cleaner. Both have received funding from the Clean Energy Finance Corporation in Australia. Rathi sat down with MicroTau founder Henry Bilinsky and Novalith Chief Executive Officer Steven Vassiloudis to understand the challenges their startups face and where they find optimism.

Before he founded the geothermal startup Fervo in 2017, Tim Latimer was a drilling engineer for the oil and gas industry — a job he loved. “Honestly, if it wasn't for climate change, I probably wouldn’t have ever changed my career,” he says this week on Zero. Now Latimer is applying his drilling know-how to Fervo’s wells, supercharging their energy production in the process. The company opened its first power plant in Nevada late in 2023, and is now in the process of opening another plant in Utah. Latimer and Akshat Rathi chat about opportunities in geothermal, the infernal permitting process, and why Fervo has its sights on expanding into Kenya, Indonesia, Turkey and the Philippines.

The “cold chain” that delivers our food is inconspicuous but vast. The US alone boasts around 5.5 billion cubic feet of refrigerated space; that’s 150 Empire State Buildings’ worth of freezers. Now, the developing world is catching up. On Zero, Nicola Twilley, author of Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves, discusses how refrigeration became so ubiquitous and what our reliance on it means for our palates and the planet.

This week on Zero, reporter Akshat Rathi sits down with Renee Salas, an emergency medicine physician at Massachusetts General Hospital and Harvard Medical School and a leading expert on the health impacts of global warming. The intersection of health and climate change is a growing area of research, and an increasingly urgent one: Heat deaths among seniors, for example, are projected to increase 370% by mid-century. But even the young and relatively healthy are at risk. “The take-home I want everyone to go away with is that we all are at risk for this,” Salas says, “especially as we get into more and more extreme conditions.”

Upgrading the grid for a net-zero world isn’t just a matter of building new infrastructure. Yes, miles of additional cables will be needed, as will more transformers, more substations and more engineers and technicians. But plenty of existing technology will also need to be updated. On the third episode of Zero’s grid series, TS Conductor founder Jason Huang discusses the material science breakthroughs that have enabled his company to create cables that have twice the conductivity of existing cables — and just as much strength.

As the world moves away from fossil fuels, the electricity grid will need to be able to handle a greater and greater load. In the second installment of Zero’s grid series, Akshat Rathi sits down with Scottish Power CEO Keith Anderson to talk about what that looks like in the UK. They discussed the promise of GB Energy, the challenges of hiring qualified engineers, and what the new Labour government can do to speed up the UK’s energy transition.

Even before we turn on a light switch or plug an appliance into an electric outlet, the atoms that power our daily life have traveled a long journey across the grid to reach our homes. And to meet the demands of a net zero future, that grid will need an upgrade. BloombergNEF analysis estimates that the world will need to nearly double its grid network to 111 million kilometers– a distance almost three quarters the way to the sun– by 2050. How will we get there? Former BNEF grid expert Sanjeet Sanghera, who is now working on strategic futures at the National Grid, tells Akshat Rathi about the challenges and opportunities presented by the enormous transformation of the world’s biggest machine.

Lucie Pinson is a climate activist focused on the banks that fund fossil fuel projects. But she doesn’t march, chant, picket corporate headquarters, or glue herself to the road. Instead, she and her team at the Paris-based nonprofit Reclaim Finance get to know Corporate Social Responsibility officers, trawl through company statements and portfolios, and join shareholder calls. Reclaim Finance’s strategy is all about finding ways to pressure big financial institutions from the inside– and it works. She tells Akshat Rathi about some of the successes her organization has had, and why even bank employees who don’t care about green issues might find reasons to work with her.
