Catalyst with Shayle Kann

We buy insurance for everything – our cars, our houses, our health. But climate tech insurance? That’s a new one.   When Jeff McAulay was working in solar, he discovered one major roadblock to scaling up climate tech. Solar developers didn’t have the right kind of insurance to cover their risks. So Jeff co-founded Energetic Insurance.   Turns out, insurance solves problems beyond solar. Jeff says...

This week, we're featuring an episode of The Carbon Copy. Batteries are everywhere. In our electronics, our power tools, our electric grid, and in our cars. And almost all those batteries use a lithium-ion chemistry. The Imperial Valley in southern California is home to the Salton Sea, a land-locked body of water that contains vast reserves of lithium. California Governor Gavin Newsom called the r...

There’s momentum building for electrification. But when will electrification take off as a mainstream movement? And what companies can provide electrification solutions to consumers at scale? One strong candidate is Sunrun. It’s the leading residential solar company in the U.S., after SolarCity years ago, and acquiring its next-biggest competitor Vivint solar more recently. Sunrun has also become...

Chemicals might be the most daunting industrial sector to decarbonize. Unlike concrete and steel, where the end products are largely uniform, refineries spit out thousands of different chemicals through a dizzyingly complex set of processes. These end products are, in turn, used in everything from plastics to fertilizers to pharmaceuticals to clothing.  The International Energy Agency predicts tha...

Biotech has enormous potential across a wide array of climate solutions. It can be used to create alternative proteins, remove carbon from the atmosphere, clean up fertilizer, or to create renewable fuels. But it also comes with some scaling challenges.  This week, Shayle talks about the intersection of biotech and climatetech with Arye Lipman. Arye is a biologist and a general partner at MarsBio,...

First-of-a-kind projects are, by definition, unproven. Despite the abundance of capital in climate tech these days, the valley of death for new technologies still exists. But there are solutions. And this week on Catalyst, we have a case study of one of them.  The U.S. Department of Energy’s Loan Programs Office has $40 billion of capacity to help solve this exact kind of problem. It just announce...

The common trope about fusion is that it has always been – and will always be – a decade away. So is something different happening now? Recently, we’ve seen technical achievements in fusion, like near ignition at the National Ignition Facility in August, yielding “a record 1.3 MJ in fusion energy, releasing, for the first time, more energy than the fuel capsule absorbed.” Fusion startups have also...

What exactly counts as “climate tech”? Basically all human activity is responsible for emissions, directly or indirectly. So nearly every new technology trend or capability has at least some role to play in curbing those emissions. Robotics? Sure. Artificial intelligence and machine learning, of course. Synthetic biology? Definitely.  But here's a really interesting one: quantum computing.  Mark C...

There are many pathways to decarbonize natural gas. Do we replace it, full stop? If so, with what? Or do we blend natural gas with alternatives, or rip up the old infrastructure and replace it with something new?  There's a lot to unpack here. But also a lot of opportunities for innovators in the climatetech world. To dig into it, Shayle turns to Andy Lubershane, the senior vice president for rese...

Aviation represents 2-3% of global GHG emissions. If the aviation sector were a country, its emissions would rank around 6th in the world, somewhere between Japan and Germany. If you add the additional warming impacts of aircraft contrails and estimates are that aviation contributes something like 3.5% of total anthropogenic warming. It's also another one of those notoriously tough-to-abate sector...

Stripe, a fintech startup worth $100 billion, is trying to kick-start a $1 trillion market for carbon removal. The company is being extremely transparent about its processes, which means we get a window into the exciting, messy, often very experimental world of removing gigatons of CO2 emissions from the atmosphere. Traditionally, carbon removal has involved planting lots of trees. There have also...

Can investors win by betting on early-stage innovations in hard-to-decarbonize sectors such as energy, transportation, agriculture and heavy industry?  The answer doesn’t matter only to venture capitalists. If you believe that we need fundamental science and engineering innovation to climb our way out of the climate crisis, it's an important question. Plenty of reasonable observers say the answer...

Shayle Kann has been thinking about the technology and market fixes for climate change for almost two decades. On Catalyst, he brings on the smartest people in climate tech to think through those hard problems. This show is about how we overcome the climate challenge. Not just at a theoretical level, but using actual technologies, tackling actual market structures, and accounting for the biggest v...
