The good and bad of carbon capture
Carbon capture and storage. It’s a controversial tool in the energy transition that we don’t want to use, but probably have to. Most of the scenarios in the IPCC’s Sixth Assessment Report include capturing and storing hundreds of gigatons of carbon dioxide between now and 2100. When people say carbon capture and storage, or CCS, they often mean different things. It’s a term that covers multiple technologies used to capture CO2—such as point-source and direct-air capture— and different approaches to using that CO2. With the CCS industry is in its infancy, tackling some big questions now could save us headaches down the road. Questions about CCS infrastructure use, where we’ll build it, and who will control it.In this episode, Shayle talks to Dr. Emily Grubert, associate professor of sustainable energy policy at the University of Notre Dame. She posted a Twitter thread recently about how the same CCS infrastructure actually has four different use cases:
Avoiding emissions to extend the life of fossil-fuel infrastructure
Avoiding emissions where we don’t have zero-carbon alternatives yet, like cement production
Removing carbon to compensate for other emissions, i.e. offsets
Removing carbon to draw down legacy emissions and avoid overshooting 1.5 degrees Celsius targets
They walk through each categories and cover topics like:
Which categories to prioritize over others
Avoiding the double-counting problem
Where we should use CCS vs. zero-carbon alternatives
The resource constraints on CCS, including water, land and energy
Whether we have the luxury to prioritize when we need to deploy CCS so quickly
Whether CCS customers or regulatory bodies should determine the type of CCS infrastructure we have and where we build it

The early days of transoceanic hydrogen transport
Before hydrogen makes it big, we have to overcome a massive, ocean-sized challenge: Transporting the fuel between continents. The places that will be best suited to produce hydrogen via renewables-powered electrolysis, like Australia and Egypt, will have to ship that hydrogen to demand centers in Japan, Europe, and elsewhere.And it turns out that shipping hydrogen is way harder than shipping oil or natural gas. Hydrogen has a very low volumetric energy density. Compared to one barrel of oil, the equivalent amount of gaseous hydrogen takes up way more space to transport.Fortunately, a range of technologies could solve this problem. Will one become the dominant means of transporting hydrogen across the oceans?In this episode, Shayle talks to Anne-Sophie Corbeau, a senior research scholar at Columbia University’s SIPA Center on Global Energy Policy. Anne-Sophie recently wrote about hydrogen transport for Cipher News. They cover the five leading contenders for transoceanic transport:
Liquified hydrogen
E-methane, also known as synthetic methane or carbon neutral gas
Liquid organic hydrogen carriers(LOHCs)
Methanol
Ammonia
They also discuss topics like:
Why good old fashioned pipelines might be a viable option for transport, even between continents
The challenges of converting natural gas infrastructure into hydrogen infrastructure
Why hydrogen exporters might be better off producing products made with hydrogen, such as steel, rather than the hydrogen itself

The fungus among us
More than a third of the world’s current greenhouse gas emissions from fossil fuels go through underground networks of fungi, according to a new peer-reviewed study in Current Biology.That’s a whopping 13 gigatons of carbon dioxide equivalents per year.Mycorrhizal fungi act as a symbiotic partner of plants, seeking out nutrients and bringing them back to the plants’ roots. In return, they accept carbon in the form of carbohydrates—which they then lock away in the structure of the fungi. This symbiotic relationship is nothing new to scientists; what’s surprising is the magnitude of carbon stored.But how permanent is this sink? And what can we do to support fungi as a nature-based climate solution?In this episode, Shayle talks to Dr. Heidi-Jayne Hawkins, lead author of the new paper and research director at Conservation South Africa. They cover topics like:
The evolutionary history of mycorrhizal fungi
The mechanics of fungal carbon storage, which boosts carbon storage by 5-20% more than plants alone
What we can do to support conditions for fungi to absorb carbon
Open questions about the permanence of the storage

Building out a U.S. solar supply chain
Everything, everywhere, all at once—that’s the state of the U.S. solar industry right now.Suppliers are rushing to take advantage of the Inflation Reduction Act’s generous domestic-manufacturing incentives. Major manufacturers like First Solar and Enel have announced billion dollar investments in places like Tulsa, Oklahoma and Lawrence County, Alabama.But tariffs on the import of some Chinese-made parts may resume at the end of 2024; and the industry still faces supply chain shortages and permitting backlogs.Meanwhile, the stakes are high. To reach net zero carbon emissions by 2050, the U.S. needs to install 100 gigawatts of solar per year by 2030, according to a report from the REPEAT Project of Princeton’s ZERO Lab, up from about 30 gigawatts this year. Is that achievable in this chaotic environment? In this episode, Shayle talks about the state of the U.S. solar industry with Ethan Zindler, head of Americas at BloombergNEF. They cover topics like:
Generous manufacturing incentives in the Inflation Reduction Act
Conditions to qualify for the incentives, such as meeting prevailing wages, building in “energy communities,” and sourcing domestic content
The saga of solar tariffs
Looming competition from manufacturers in Southeast Asia
How supply chain bottlenecks have eased up

AI for climate: a real world test
The list of potential uses for AI in climatetech is growing fast: developing better materials, optimizing solar farms, integrating renewables and microgrids. But many of these are still theoretical. We wanted to find a real-world application that changed the way we make climatetech.So we decided to come up with our own test run.Back in March Duncan Campbell, vice president at Scale Microgrids, used ChatGPT to code some battery dispatch software and tweeted about his experience. Duncan isn’t a professional software developer, but he still came up with some promising results. Could a non-coder like Duncan use AI to do the work of several climatetech coders?We invited Duncan to do it again and ramped up the challenge. We recruited Seyed Madaeni, CEO and co-founder of Verse to create a challenge for Duncan. Seyed is an expert in AI and the software used in electricity markets. He routinely sends “problem statements” to his team of software developers to create new software. This time, he sent a problem statement to Duncan that reflects real world conditions, one that we might actually assign to real engineers to solve.The challenge? Develop battery dispatch software using ChatGPT. In this episode, Duncan presents his results to Shayle and Seyed. They talk about things like:
The different methods of optimizing battery dispatch, from old-school Excel sheets to more sophisticated software written by coders
Seyed’s process of assigning a problem statement to his engineering team and the simplified version he sent to Duncan
Duncan’s process of iteratively working with ChatGPT-4 to develop and debug the code
Why working with ChatGPT is like working with a bunch of really fast, but really inexperienced junior coders

The carbon market’s quality problem
Voluntary carbon credits are a lot like used cars; you really have no idea what their quality might be. Or maybe they’re more like expensive bottles of wine. Most people (or at least Shayle) can’t tell if they’re buying good quality wine. If it’s expensive, it must be good, right?That’s the logic that has plagued voluntary carbon markets for years. A carbon credit can work in two ways. First, it can avoid 1 metric ton of emissions that would have otherwise happened by, for example, preventing deforestation. Alternatively, a credit can directly remove a ton of carbon from the atmosphere through methods like direct air capture or biochar.But widespread reporting reveals that most credits don’t do what they say they do. Just this month the CEO of the world’s leading certifier stepped down after an analysis by The Guardian found that over 90% of rainforest carbon credits were worthless. In May, a new $1 billion California lawsuit alleged that the credits that Delta relied on for its claim of reaching carbon neutrality claims were bogus.Carbon credits are in crisis at the same moment we need to massively scale up carbon credits to meet net zero goals. So what do we do about these quality problems? In this episode, Shayle talks to Allister Furey, co-founder and CEO of Sylvera, a company that rates the quality of credits, akin to what agencies like Moody’s or Standard & Poor’s do for bonds.Shayle and Allister cover topics like:
The history of the first voluntary carbon markets and their early problems, like producing fluorocarbons just to destroy them
The state of the current market, including its size, segments and prices
The wide gulf in price between the cheapest avoidance credits and the most ambitious engineered removal credits
Why Allister thinks we need to be on a “war footing” to reach to the highly ambitious carbon removal targets to meet net zero, such as growing the market from $2 billion to $1 trillion by 2050
Why high prices do not necessarily mean high quality

Keeping copper from limiting the energy transition
The energy transition is fueling skyrocketing demand for copper, an essential metal for renewables, batteries, and other climatetech.But supply isn’t keeping up. There’s more than enough copper in the earth’s known reserves to supply our growing demand for the metal, but supply is stagnating due to rising extraction costs and decades-long lead times to open new mines.A July 2022 report from S&P Global predicts that demand could begin to exceed supply in just a few years.. Without action, a growing supply gap could last into the 2050s, hampering the speed and scale of the transition.What can we do about it?In this episode, Shayle talks to Cristóbal Undurraga, the CEO of copper mining technology company Ceibo. They talk about the causes of stagnating supply and the technologies that could help increase production. They cover topics like:
Energy usage and carbon emissions in copper supply chains
The limitations of scrap recycling to meet growing demand
The geopolitics of copper supply chains, including China’s major role in smelting
The pros and cons of the two major copper extraction methods – concentration and electrolysis
The two major types of ore – copper oxides and copper sulfides, and why one is so much harder to mine
The long lead times to build new mines and why constructing new ones isn’t easy
Ceibo’s approach to increase mine capacity using novel electrolysis technology for copper sulfides

Four ways to store sunlight
Are you a utility or climatetech startup looking to understand how artificial intelligence will shape your company? Come to our one-day event, Transition-AI: Boston, on June 15. Our listeners get a 20% discount with the code PSPODS20.On the Catalyst with Shayle Kann podcast this week:The good news: the U.S. has about 47 days’ worth of energy stored up for later use. The bad news? Virtually all of it is in the form of fossil fuels – coal, oil and natural gas. By comparison, if you add up all the energy stored in batteries, pumped hydropower and other zero-carbon storage, it adds up to just a few seconds’ worth.This small scale of low-carbon energy storage is a big problem. We’re building out intermittent renewables fast, and we need enough energy storage to back up wind when turbines slow down and solar when the sun isn’t shining. But there are technologies that could get us there. In this episode, Shayle talks to his colleague Andy Lubershane, who is a partner and head of research at Energy Impact Partners. Andy recently wrote a piece called Four ways to store sunlight, which compares lithium-ion batteries, heat storage, ion-air batteries, and hydrogen. Andy and Shayle cover topics like:
The storage trifecta: short duration, diurnal, and multi-day seasonal
Andy’s guess at how low the price of lithium-ion batteries could go
Why we would use heat storage and hydrogen, despite their low round-trip efficiencies
Why molten-salt heat storage didn’t take off
High hopes for iron-air batteries’ low costs
Blending hydrogen into gas turbines
How all these technologies are competing against carbon capture and storage (CCS)

Unpacking EPA’s newly proposed power emissions rule
Are you a utility or climate tech startup looking to understand how artificial intelligence will shape your company? Come to our one-day event, Transition-AI: Boston on June 15. Our listeners get a 20% discount with the code PSPODS20.Last year, the Supreme Court struck down the EPA’s first attempt to limit greenhouse gas emissions from existing power plants. But it also preserved the EPA’s authority to regulate greenhouse gas emissions. The agency just needed to find the right approach. The question for the EPA was: What legal tools would pass the scrutiny of the court?Last week, Biden’s EPA came out with its answer. The proposed plan requires new and existing power plants to meet emission standards. The agency estimates that the rule would reduce GHG emissions by a total 617 million tons through 2042, a small but meaningful fraction of the total. Right now the U.S. power sector emits about 1.5 billion tons per year. It’s an approach that dovetails with the Inflation Reduction Act (IRA), which is expected to dramatically reduce the cost of key emissions-reducing technologies, such as carbon capture and storage (CCS) and hydrogen. If the IRA was the Biden administration’s carrot for reducing climate emissions, then the new rule is the stick. In this episode, Shayle unpacks the proposal with John Larsen, who leads U.S. climate policy research at the Rhodium Group. In March, John’s team modeled the impact of hypothetical power emissions standards on the U.S. power fleet, finding that many coal plants might shut down rather than install CCS.Shayle and John dig into specifics, like:
The four main options available to power plant operators under the proposed rules: shut down, install carbon capture and storage (CCS), co-fire with hydrogen, or just run less
The differences in rules for new and existing plants
How the standards become more stringent with higher capacity factors
The role of states in the rules and the “off-ramps” they could use to get around some of the rules
The power plants that would be exempt from the rules, such as gas peaker plants with low capacity factors
What the changing economics of CCS and hydrogen could mean for the effect of the regulations
The legal gauntlet that the plan is sure to face, including lawsuits from Republican states

The great Bitcoin energy debate
Depending on who you talk to, Bitcoin mines are either great for the grid or the worst thing that’s ever happened to it. These warehouses of computers essentially turn electricity into bitcoins. Proponents argue that mines can do a number of things for the grid, like:
Support grid reliability by reducing demand during peak hours
Incentivize new renewable generation by raising the prices that solar and wind farms receive
Reduce methane emissions by capturing flare gas from fossil fuel wells and then using that gas to generate electricity for mine operations
Meanwhile, opponents argue that the mines raise emissions and electricity prices. So how do we make sense of the great Bitcoin energy debate?In this episode, Shayle talks to Ben Hertz-Shargel, global head of grid edge at Wood Mackenzie. The New York Times recently reported on the role of Bitcoin mining on the grid, and Ben was part of a team that contributed to the report.Shayle and Ben discuss:
How Bitcoin mines affect electricity prices for nearby consumers
Whether mines use only excess renewable generation or incentivize fossil-fuel generators to ramp up
What mines’ load profiles say about their flexibility and price-sensitivity, especially during peak demand
The evidence on whether mines are signing long-term power purchase agreements, repowering mothballed projects or otherwise helping to incentivize new renewables construction
