While aviation may be converging on one main pathway to decarbonization — sustainable aviation fuel — maritime shipping may require a more diverse set of solutions: a portfolio of fuels, energy efficiency, and on-board carbon capture and storage. But each technology has operational and capital challenges. So what will it take to scale them up? In this episode, Shayle talks to Dr. Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation. Ocean-going shipping consumes about 300 million...

Investment is on the rise in geothermal, where advances in drilling techniques are driving down the cost of generation right as the grid needs more clean, firm, dispatchable power to meet rising load growth. And enhanced-geothermal startup Fervo is leading the pack of entrants, signing agreements to provide power to Southern California Edison and Google.  So how ready are these next-generation geothermal technologies to scale? In this episode, Shayle talks to Dr. Roland Horne, professor of...

New electric vehicles — including both battery electric and plug-in hybrid vehicles — make up nearly half of new car sales in China. Compared to slowing EV sales in Europe and the U.S. the Chinese market is booming.  So what’s going on? In this episode, Shayle talks to TP Huang, who writes a Substack about EVs, clean energy, and other tech focused on China. (Editor's note: TP Huang is a pseudonym, used for family reasons.) Shayle and TP cover topics like: How EVs became extremely cost...

Driven by the AI boom, data centers’ energy demand could account for 9% of U.S. power generation by 2030, according to the Electric Power Research Institute. That's more than double current usage. So how do we meet that demand? And what impacts will it have on the grid and decarbonization? In this episode, Shayle talks to Brian Janous, former vice president of energy at Microsoft and current co-founder of Cloverleaf Infrastructure. Brian talks through the options for meeting data center...

Tesla’s Master Plan Part 3 lays out the company’s model for a decarbonized economy — and makes the case for why it's economically viable. It outlines a vision for extensive electrification and a reliance on wind and solar power.  In this episode, Shayle talks to one of the executives behind the plan, Drew Baglino, who was senior vice president for powertrain and energy at Tesla until April when he resigned. In his 18 years at Tesla he worked on batteries, cars, and even Tesla’s lithium...

Batteries are making their way into more passenger cars and commercial vehicles than ever before, but the limits of electrification mean that we’ll likely need alternative fuels to decarbonize heavy transport like ships, planes, and trucks.  So what are those fuels and what modes of transport do they suit best? In this episode, Shayle talks to his colleague Andy Lubershane, partner and head of research at Energy Impact Partners. They talk through the limits of electrification and the...

This week, we’re featuring a crossover episode of With Great Power, a show produced by Latitude Studios in partnership with GridX. Subscribe on Apple, Spotify, or wherever you get podcasts. Ahmad Faruqui has been researching electricity pricing since the mid 1970’s, when the cost of a kilowatt-hour was flat. But in the 80’s and 90’s, he started working on dynamic pricing – pioneering the concept of time-of-use rates. The big breakthrough for time-of-use rates came during the fallout from the...

The U.S. rooftop solar market has tanked. Residential applications in California, the largest market in the country, plunged 82% from May through November 2023 compared to the same period in 2022. Contractors are going bankrupt. The big culprits are high interest rates and California’s subsidy cuts. But there are some bright spots. Battery attachment rates in California have surged. So what will it take to revive the U.S. rooftop solar market? In this episode, Shayle talks to Jigar Shah,...

Airlines are lining up to buy as much sustainable aviation fuel (SAF) as they can, despite it costing two to three times more than conventional jet fuel, according to BloombergNEF. United Airlines has secured 2.9 billion gallons of SAF over, and others like Delta, Air France-KLM, and Southwest have secured around 1 billion gallons each. And yet to meaningfully decarbonize aviation, the SAF market needs to grow thousands of times larger than it is today. BloombergNEF estimates that global...

This week, we have something a little different: a news quiz.  We recently took the stage with four investors at the Prelude Climate Summit — armed with a bell, a buzzer, and four different categories of questions. We tested two teams of venture investors on their knowledge of the most recent industry news. Shayle Kann and Cassie Bowe, partners at venture firm Energy Impact Partners, are team High Voltage.  Dr. Carley Anderson, principal at venture firm Prelude Ventures, and Matt Eggers,...

The IPCC says that we likely need to capture hundreds of gigatons of CO2 if we want to limit global warming to 1.5 degrees Celsius. So what are we going to do with all that carbon? In this episode, Shayle talks to Julio Friedmann, chief scientist at Carbon Direct. Julio says we will store the vast majority of that CO2. But the markets for using CO2 in things like concrete, fizzy water, and chemicals will play an important role in developing the carbon management economy. Shayle and Julio...

Rare earth elements (REEs) are essential ingredients in electric vehicles, wind turbines, and many electronics. As with most critical minerals, China controls the vast majority of the REE supply chain. And so when it banned the export of REE processing technology last December, it raised concerns about supply. So what will it take to secure the supply of REEs?  In this episode, Shayle talks to Ahmad Ghahreman, CEO and cofounder of Cyclic Materials, a rare earth elements recycling company....

A little-known U.S. law called the Jones Act shapes climate tech in weird ways — like hindering offshore wind deployment and pushing up energy prices. The law, part of the Merchant Marine Act of 1920, requires all cargo shipped between U.S. ports to be carried by ships that meet strict standards. Those ships must be built in American shipyards, owned by an American company, registered in the U.S., and crewed by a majority American crew. As a result, building cargo ships in the U.S., and...

This week we’re bringing you a deep dive into battery supply chains — the season premier of The Big Switch, a show that Latitude Media makes in partnership with Columbia University’s SIPA Center on Global Energy Policy. Across this five-episode documentary series, hosted by the acclaimed energy scholar Dr. Melissa Lott, we examine every step of the sprawling global supply chains behind lithium-ion batteries. In this first episode, we break apart one of the battery cells that was in the...

The lithium-ion battery business is taking off, and the battery recycling business is close behind. Financiers are pouring over a billion dollars into recycling companies like Redwood Materials, Ascend Elements, and Li-Cycle. But success depends on a steady supply of used batteries, and with batteries lasting longer than expected — and the battery market still in its infancy — there just aren’t enough dying batteries to go around.  As a result, a significant portion of recyclers’ feedstock is...

The electricity gauntlet we covered last year has been having a moment in the national spotlight, with coverage of rising load growth in the New York Times, the Wall Street Journal, and the Washington Post.  On one side of the gauntlet, demand for electricity is rising, driven by new loads like EVs, data centers, and electrification. On the other side, electricity supply is slow to grow, bogged down by years-long interconnection queues, the immense challenges of building transmission, and...

The U.S. Securities and Exchange Commission approved new rules this month on what information companies must disclose about their greenhouse gas emissions and climate risks, but notably dropped more stringent requirements that the commission initially proposed.  Despite being halted by lawsuits, the rules are a significant win for climate transparency. But they’re not as strong as existing climate disclosure regulations in California and the European Union, where many multinational...

Two major indicators of climate tech stocks – the S&P Clean Energy Index and the MAC Global Solar Index – are significantly trailing the overall market. They’ve been declining for months, down from their mid-pandemic highs when they performed far better than the rest of the economy. So what happened to climate tech investments in the public markets? And what do these investments tell us about the coming year for climate tech? In this episode, Shayle talks to Shanu Mathew, portfolio...

The first wave of digital grid infrastructure in the U.S. didn’t quite deliver on its promises. More than 100 million smart meters have rolled out across the country, buoyed initially by billions in federal funding. But instead of using them for exciting things like time-of-use pricing and automated demand response, utilities used them for more mundane things like automated billing, according to a whitepaper from Guidehouse.  Could the new wave of AI-based grid tech be different? In this...

The carbon removal market could reach $400 billion to $1.6 trillion by 2050, according to McKinsey. But it’s got a long way to go. Right now the market is wild, unexplored territory filled with unproven technologies, murky cost curves, and a motley mix of price points and standards. The hope is that one day it becomes a standardized commodity market of high-quality, durable removals. But for now, brave buyers have to wade into the wilds and see what works. So what does that look like – and...

The list of things that depend on transformers is long: new housing, EV chargers, renewable projects, and more. That’s why skyrocketing lead times and prices for grid equipment that raises or lowers voltage is a real problem. The wait for a new transformer has jumped to over two years, according to WoodMackenzie. Back in 2020 it took just a few months, according to Tim Mills, CEO at transformer manufacturer ERMCO. WoodMackenzie found that prices, meanwhile, have risen over 60% since 2020.  So...

It's been a year and a half since the Inflation Reduction Act was passed. In that time, we've seen $110 billion in planned investments for factories that are pumping out electric cars, batteries, solar modules, and wind towers.  The upper end of 2030 forecasts show nearly twice as much zero-carbon generation getting built compared with scenarios without the law in place. Much of this activity is the result of a new shift in the US tax code that allows wind, solar, storage, hydrogen, carbon...

There was so much to talk about in Nat Bullard’s 200-page slide deck on 2024’s biggest decarbonization trends that we broke the conversation into two parts. For the first half of our conversation with Nat, listen here.  Nat has worked as an analyst and writer in climate tech for two decades and was BloombergNEF’s chief content officer until 2022. In this second part of the conversation, Shayle and Nat cover topics like: How ESG has become the new third rail of finance, falling out of the...

We’re back for round two, with even more slides than last year. This year’s annual slide deck from Nat Bullard has 200 pages on the key trends shaping decarbonization in 2024. Nat has worked as an analyst and writer in climate tech for two decades and was BloombergNEF’s chief content officer until 2022. We’ve split the conversation into two parts. In this first part, Shayle and Nat cover topics like:  The state of batteries, including the rapid growth of LFP chemistries, the concentration of...

A recent slew negative headlines about U.S. EVs makes it feel like the sky is falling on the market. Yet the data show robust growth. Combined battery electric and plug-in hybrid sales in 2023 were up 50% from 2022. Meanwhile, EV market share reached 9.5% in 2023, up from 7.5% in 2022, according to BloombergNEF.  Still, there have been real signs of changing expectations. GM and Ford have downsized their EV ambitions. Hertz sold off 20,000 Teslas. And Elon Musk tried to temper expectations in...
