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:
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:

The U.S. power grid is clogged, and it’s holding back the energy transition.
Solar and wind farms are waiting four or more years to connect to the grid. Rising congestion costs are driving up retail electricity prices while hurting generator revenues. And the process of approving projects for interconnection is so complicated and expensive that it’s forcing developers to abandon the projects they were planning to build.
We need much more transmission capacity and a better process for connecting projects. And we need it now more than ever. Demand for power will skyrocket as we connect EVs, heat pumps and other new loads to the grid. But Rob Gramlich, our guest today, comes with good news: We did it before. We can do it again.
Rob is the founder and president of Grid Strategies. In this episode, Shayle and Rob talk through the three major challenges of transmission – congestion, interconnection, and buildout. And Rob explains how we’ve built out transmission in the past with efforts like ERCOT’s Competitive Renewable Energy Zones (CREZ) and MISO’s Multi-Value Projects (MVPs).

We’re bringing you a special crossover episode this week from Catalyst’s sister podcast, The Carbon Copy. It’s about a rogue startup that was trying to do something we’ve talked about on this show: solar geoengineering.
Last year, Time staff writer Alejandro de la Garza found himself on the floor of a hotel room in Nevada with two guys trying to cook sulfur dioxide out of a tin can.
Luke Iseman and Andrew Song are the co-founders of Make Sunsets, a startup claiming to be implementing solar geoengineering by launching weather balloons filled with SO2 into the stratosphere.
Their first experimental launch in the Mexican state of Baja California resulted in a swift regulatory response from the Mexican government. But when they ran another test launch a few weeks ago just outside of Reno, Nevada, Luke invited Alejandro to join them.
This week, we speak with Alejandro about his Time profile of the controversial startup. Plus, we talk with geoengineering experts Holly Buck and Kevin Surprise.
“Any single person you talk to in solar geoengineering research, whether they’re bullish or against it, they all think that what Make Sunsets is doing is a bad idea,” explains Alejandro.
Make Sunsets represents a turning point for the field of geoengineering, with rogue actors pushing the field from academic debate into the real world. Is the company’s recent balloon launch an act of performance art — or an open door to an uncontrolled climate experiment?

Hydropower is the world’s largest source of renewable electricity today, according to the IEA. Like gas peaker plants, it’s highly dispatchable, meaning it can complement intermittent renewables like wind and solar.
And we could get a lot more of it. The IEA estimates that we could double the amount of energy produced globally. One peer-reviewed study found that global economic potential for hydropower was 21,000 terawatt hours per year, more than five times the current generation today.
So how could we deploy more hydropower?
In this episode, guest host Lara Pierpoint talks to Gia Schneider, co-founder and CEO of Natel Energy, a hydropower technology company. One key argument Gia makes is that if we can build smaller projects with lower ecosystem impacts, we can tap into more zero-carbon power.
Gia and Lara talk through:

The battery manufacturing announcements have been coming one after another—a VW cathode facility in Canada; a Tesla factory in Mexico; a Ford battery plant in Michigan.
These companies hope to take advantage of the Inflation Reduction Act’s lucrative EV tax credits:
But there’s a catch. A whole bunch of intermediate battery products don’t fit neatly into either bucket. For example, lithium gets processed into precursor cathode active material before it becomes cathode active material, the powder that actually makes it onto the factory floor of a battery manufacturer. Battery electrolytes go through multiple processing steps, too.
Until last week, suppliers of these products were left wondering: Where should we manufacture to qualify? And for which credit?
Congress had left these details up to the Treasury Department, and on Friday regulators released guidance for these intermediate products, or “constituent materials.” The new rules pleased some and angered others.
So what do the changes mean for EV supply chains?
In this episode, Shayle talks to Sam Jaffe, our resident EV-supply-chain whisperer. He’s the vice president of Battery Storage Solutions at E Source. He’s come on the show before to talk about the holy grail of batteries and the basics of the IRA’s EV tax credits.
This time, Sam explains the new Treasury guidance.They cover topics like:

The run on Silicon Valley Bank (SVB) earlier this month was a hair-raising experience for anyone in climatetech. The bank catered to entrepreneurs in tech, especially climate. So when news of SVB’s troubled assets hit social media, startups scrambled to withdraw millions of dollars and draft emergency plans to make payroll. But after the Federal Insurance Deposit Corporation (FDIC) took over SVB and another troubled regional institution, Signature Bank, the dust started to settle. The FDIC announced that it would insure the full deposits at SVB, above the $250,000 guarantee.
But how did this all happen? And what does it mean for climatetech today?
In this episode, Shayle talks to Saloni Multani, partner at Galvanize Climate Solutions and former chief financial officer for Joe Biden’s 2020 campaign. She came on the show last May to explain what the economic downturn meant for climatetech. This time Saloni and Shayle cover topics like:

Landfills, dairy farms and wastewater plants all emit methane, the potent greenhouse gas produced when organic material decomposes in the absence of oxygen.
But instead of emitting that methane (often called biomethane or waste methane), it’s possible to capture and refine it, resulting in renewable natural gas, or RNG. Capturing methane that would have been emitted anyway (something that’s still up for debate) creates RNG that’s carbon neutral or carbon negative. And using that RNG to displace fossil-fuel derived natural gas can cut overall emissions.
Big players in energy are betting big on RNG. Last fall BP acquired RNG producer Archaea for $4.1 billion, Shell bought Nature Energy for $2 billion and NextEra purchased $1.1 billion in RNG assets from Energy Power Partners.
So what’s behind this recent flurry of activity? And to what extent could RNG actually offset carbon emissions?
In this episode, Shayle talks to Brandon Moffatt, cofounder of Stormfisher, an RNG and hydrogen producer.

Nitrous oxide or N2O is the third largest source of GHG emissions behind carbon dioxide and methane. Also known as laughing gas, it’s long-lived like carbon dioxide and incredibly potent like methane. And it accounts for about 6% of global warming.
So where does it come from? And what do we do about it?
In this episode, Shayle talks to Eric Davidson, professor at the University of Maryland Center for Environmental Science, and principal scientist at Spark Climate Solutions. Eric studies the surprising source of nitrous oxide: bacteria in the soil. Eric and Shayle talk about topics like:

We’re bringing you a special crossover episode this week from Catalyst’s sister podcast, The Carbon Copy. I host the show and we did an episode recently about this urgent climate tech problem: America’s shortage of electricians.
To decarbonize the economy, we need to electrify everything. That means installing millions of heat pumps, EV chargers, electric water heaters and rooftop solar panels.
But there’s one big problem: finding enough electricians to make it happen. Electricians across the country are flooded with work — and just as demand is skyrocketing, many in the field are nearing retirement age.
This week, in a special collaboration with Grist, reporter Emily Pontecorvo discusses where to find all the electricians we need to electrify everything and how we can train enough new entrants to the field to meet our climate goals. Read Emily’s feature article.

Last year’s surge in oil prices brought record windfall profits for oil majors, and a boon for investors. But historic trends don’t favor fossil fuels.
From 2010 to 2020, the oil & gas sector underperformed the broader S&P 500 index. The sector gained 6% over that period, while the benchmark S&P index grew 180%. Some called it a "lost decade" for fossil fuel investors.
“If anything, oil's been a drag,” says Zach Stein, the co-founder and CEO of Carbon Collective, a company building climate-focused portfolios for investors and employer 401(k) plans.
The recent surge for the oil and gas sector shows how fundamental fossil fuels are for today's economy. But looking forward, oil is facing the most significant competition it has ever seen, thanks to electrification and clean energy.
That view of the long-term threat to fossil fuels drove Zach to co-found Carbon Collective – with a mission to build funds around industries that will deliver strong returns in a climate-constrained world.
In this episode, produced with Carbon Collective, Zach Stein talks with Stephen Lacey about trends in sustainable investing – how to define the category, identify good investments, and separate it from the confusing world of ESG.
If you want to invest sustainably – at work or individually – you can learn more at carboncollective.co. There, you can see how the portfolios are built and read more about the company's theory of change.
