Biomass. It's the organic matter in forests, agriculture and trash. You can turn it into electricity, fuel, plastic and more. And you can engineer it to capture extra carbon dioxide and sequester it underground or at the bottom of the ocean. The catch: The world has a finite capacity for biomass production, so every end use competes with another. If done improperly, these end uses could also compete with food production for arable land already in tight supply. So which decarbonization solutions ...
There’s a bottleneck in climate tech that we don’t talk about enough: land availability. It’s a physical resource you need to support biomass, renewables, mineral mining, and other essential tools of decarbonization. So how much is enough, and where do we need it? In this episode, Shayle talks to his colleague Andy Lubershane, managing director of research at Energy Impact Partners. Andy argues that land—geography, landscape and the rights to land—will be a common constraint among climatetech so...
Consumer energy data is vital to the energy transition, especially distributed energy resources (DERs). For example, a rooftop solar company needs consumer energy data to analyze bill savings from a potential solar installation. An electric vehicle (EV) charging company needs it to offer a customer special rates on EV charging. But that data has long been incredibly difficult to access – available only in PDFs and hard-to-access utility databases – often coming in very different formats and stan...
Stock markets are in decline. Inflation is on the rise. Interest rates are up. Private tech companies are laying off workers. Is this the long-awaited market correction that never quite materialized during the bull market of the last 13 years? And what does it mean for climate tech? In this episode, Shayle talks to Saloni Multani, a partner at Galvanize Climate Solutions and former chief financial officer for Joe Biden’s 2020 campaign. Shayle and Saloni place the current moment in historical con...
We’re reversing roles today by taking listener questions for our host, Shayle Kann. He’s usually the one interviewing our guests, but he also has expertise (and maybe a few hot takes) to share. He leads a $350 million fund that invests in early-stage climate startups, so he spends most of his time trying to figure out which technologies and businesses will help us decarbonize as quickly as possible. GreenBiz senior energy analyst Sarah Golden joins the show to ask Shayle your questions and disse...
Carbon Dioxide Removal (CDR) is having a moment. The most recent report from the Intergovernmental Panel on Climate Change found that the world cannot meet the targets of the Paris Agreement without removing hundreds of gigatons of carbon from the atmosphere. Big companies like Alphabet, Stripe and others have formed the Frontier Fund, a nearly $1 billion joint-effort to jump-start the market to purchase CDR offsets. Elon Musk is even sponsoring a $100 million X-Prize focused on it. We’re not ta...
A massive green hydrogen project in Utah has won a $504.4 million conditional loan guarantee from the U.S. Department of Energy’s Loan Programs Office. The project, called Advanced Clean Energy Storage (ACES), will generate hydrogen from renewables and store it deep underground in what’s called a salt dome. ACES will use that stored hydrogen to generate electricity in a hybrid power plant, running on both natural gas and hydrogen. ACES is one of the many planned hydrogen hubs in the U.S., and on...
The metals used to make batteries are in hot demand. In 2021, the price of one form of lithium skyrocketed by over 400%. Automakers are racing to lock up supply deals for key minerals as they roll out new electric-vehicle models. And the market value of companies with mining assets, or new technologies to unlock them, has skyrocketed. What’s behind this scramble for metals and what does it mean for the energy transition? In this episode, Shayle talks to Kurt House, chief executive officer and co...
Support strong climate journalism! Donate to Canary Media to celebrate its one-year anniversary. Conventional livestock agriculture, especially beef production, is a huge climate problem. It makes up 14.5% of global greenhouse gas emissions. But there’s good news: alternative proteins are hot. Brands like Impossible Foods and Beyond Meat rely on alternative proteins to replicate the taste and texture of conventional meat and dairy – but with drastically less carbon pollution. Alternative protein...
Support strong climate journalism! Donate to Canary Media to celebrate its one-year anniversary. After a string of relatively high profile failures and cost overruns, point source carbon capture and storage (CCS) – that is, capturing carbon dioxide directly from flue stacks at industrial and power generation facilities – fell into disrepute. Many projects were shelved. And yet, in just the first nine months of 2021 the global capacity of planned CCS projects grew 50% to 111 million tons, which w...
Europe imports about 45% of its natural gas from Russia. As the conflict in Ukraine escalates, pressure is mounting for Europe to wean itself off Russian energy as quickly as possible. European sanctions against Russia have excluded the energy trade, meaning that European purchases of oil and gas – which fund about 40% of Russia’s federal budget – are in effect funding the Russian war effort in Ukraine. So how could Europe eliminate the import of Russian fossil fuels? In this episode Shayle talk...
Carbon markets of all types – avoidance, removal, voluntary, compliance – are hot. Startups are sprouting up, looking to develop, broker and verify new kinds of credits. More than a decade ago there was a similar flurry of excitement around offsets, followed by a big crash in carbon markets. Experts blamed the Great Recession, but also a lack of trust and transparency in the offsets themselves. Will this time be different? In this episode, Shayle talks about what’s changed with Nat Bullard, chie...
In the 90s batteries powered your camcorder and boombox. Then your phone. Now they’re running your electric vehicle (EV), and in some cases, even your house. At what scale will batteries meaningfully reduce greenhouse gas emissions? We may be nearing an inflection point with electric vehicle batteries, but we’re nowhere near as close with grid storage technologies. What’s it going to take to get there? Guest host Lara Pierpoint explores this question with battery expert – David Schroeder, chief ...
For nearly two decades, the terms "smart grid" and "grid edge" have been used to define the digital layer of the electricity system that can help integrate more rooftop solar panels, EVs, smart meters, and home batteries to avoid outages and save customers money. But even with massive increases in computing power, utilities are still lagging in technology to communicate with DERs (also known as grid-edge assets) and the computing power to crunch all that data. In this episode, what can the grid ...
It may not get the same attention as higher-profile sectors, but cooling accounts for 4% of global greenhouse gasses emissions. That's more than even aviation or shipping. Demand for cooling is expected to triple by 2050. In places where global warming is triggering intense heat waves, cooling has become a matter of life and death. And yet, cleaner, more-efficient air conditioning technology exists. Why aren’t we using it? And how do we make it affordable and widely available? In this episode, g...
Traditional nuclear power is bogged down by cost overruns and concerns about safety and waste. But does it have to be that way? Could we deploy scaleable reactors that are cheaper, safer, and that produce less waste? Advanced nuclear startups in the U.S. certainly think so. In this episode, guest host Lara Pierpoint speaks with Jake DeWitte, co-founder and CEO of Oklo, one of many advanced nuclear companies that have emerged in recent years. Lara and Jake survey the polarized landscape of nuclea...
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 there are unaddressed risks associated with many new climate technologies that can prevent developers fr...
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 region the "Saudi Arabia of Lithium." If mined, it could completely reshape the global supply chain. ...
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 a major player in residential batteries. And it started to push its way into the residential EV char...
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 that chemicals will be the largest source of demand growth for oil through 2050. A wide range of approac...
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, a bio-focused early-stage fund. He also writes a Substack newsletter on biotech called The Last Grea...
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 announced its first conditional commitment for a $1 billion loan guarantee to help Monolith scale up its firs...
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 enjoyed a recent barrage of mega-funding. First, General Fusion raised $130 million. Then Helion En...
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 Cupta is convinced it may actually be one of the most important technologies we'll invent to mitigate 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 research & strategy at Energy Impact Partners. Andy and Shayle talk about natural gas’ existential threat...
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 sectors. Jet fuel (a.k.a. kerosene) is pretty magical. It has enabled the movement of people and the globa...
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 been a select few companies toiling away at expensive-but-promising direct-air capture. But it turn...
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 is no. Case in point: The 2016 MIT report Venture Capital and Cleantech: The Wrong Model for Clean En...
