⚡ Carbon & Energy

"Saving the Planet with Seaweed" | Invested In Climate

Guests: Alexia Akbay | Founder | Symbrosia &
Julia Marsh | CEO | Sway
Time Saved: 40 Minutes

Selected Quote:

[4:19] AA: “At Symbrosia, we grow "new species" of algae in terms of commercially utilizing the species as a cattle feed additive to reduce their enteric methane emissions, which is the largest source of greenhouse gasses affiliated with livestock. [...] With a sprinkle of the seaweed in the feed, you can reduce their methane emissions by over 80% [...] in a commercial setting. So [a] pretty major reduction in this source of emissions."

"What’s Holding Up Hydrogen in Europe?" | Catalyst with Shayle Kann

Guest: Gniewomir Flis | Hydrogen Consultant
Time Saved: 42 Minutes

Selected Quote:

[25:54] GF: "The issue we will run into is that hydrogen is very expensive to transport. So I think the way it will be split is that when hydrogen needs to be produced for hydrogen sake, [...] in other words for end users that require hydrogen, whether that's heavy trucking, whether that's steel, [...] in the chemical industry, there is an appetite to produce that within Europe. [...] On the other hand, there are certain molecules that have some of the transport options for hydrogen, things like ammonia or methanol, [...] that can be produced abroad and imported into Europe. [...] Some countries have a natural competitive advantage in access to cheaper, renewable resources, and thereby making their hydrogen production costs lower."

"The Current State of Investment in the Energy Transition" | The Energy Gang

Guests: Nneka Kibuule | Principal | Aligned Climate Capital &
Samuel Scroggins | Investment Banker | Lazard
Time Saved: 58 Minutes

Selected Quote:

[33:41] SS: "In practice, we are not seeing a slowdown of capital being deployed in the sector. So I don't think that investors are underwriting investments, assuming that there's a fundamental negative shift away from supportive policy. And [...] even outside of subsidies, renewable energy technologies are cost competitive with fossil fuel generation technologies."

"Turning Pollution into Profit" | Business Breakdowns

Guest: Chadd Garcia | Lead Portfolio Manager | Ave Maria Focused Fund
Time Saved: 45 Minutes

Selected Quote:

[5:16] CG: "Companies that are coming along now are taking landfill gas and filtering it to isolate the methane to such a degree of purity that the methane can be sold into natural gas pipelines. If you look at the problems that Archaea solves: First, it eliminates the foul odor associated with landfills, it generates a less harmful greenhouse gas that's released into the atmosphere, it generates substantial economic value for Archaea as well as landfill operators if they're able to process the landfill gas and turn it into methane."

"Engineer Biomass Waste to End Microplastic" | This Week in Startups

Guest: Robert Luo | Founder & CEO | Mi Terro
Time Saved: 37 Minutes

Selected Quote:

[19:48] RL: "We are solving a problem that happens every single day to everybody, but we don't talk enough about, which is microplastic, [...] [focussing on] detergent and laundry pods, [...] [that] are made from a synthetic plastic polymer called PVA, polyvinyl alcohol. [...] 20 billion of these pods are produced in the US every single year, and 8,000 tons are just flowing into the ocean. Our solution is to replace these microplastics [...] [with] biodegradable and water soluble resins that are good for the environment and leave no microplastic whatsoever."

"Reducing Climate Emissions in Battery Manufacturing" | Climate 21

Guest: Tom Einar Jensen | CEO | Freyr Battery
Time Saved: 29 Minutes

Selected Quote:

[2:34] TJ: "Batteries, and lithium ion batteries [...] in particular, [are] becoming the core enabler in our opinion for the energy transition that we are in. That means that having lithium ion batteries produced in the least carbon intensive manner is possible to both decarbonize the transportation sector, [...] but that also [...] as a core enabler for decarbonizing energy systems. [...] What we mean by clean battery solutions [...] is that the batteries themselves need to be produced in the cleanest manner possible, meaning lowest possible carbon footprint along the entire value chain of producing the battery."

"Can Dairy Be Regenerative" | The Proof with Simon Hill

Guest: Nicholas Carter | Co-Founder |
Time Saved: 1 Hour 27 Minutes

Selected Quote:

[40:16] NC: "There's a couple of examples [of dairy farms] that have been technically certified as regenerative. [...] They're integrating cover crops or integrating other crops on their land. Ideally, it's compost and green manures, too. [...] It's a game of trade offs. You are probably using more land, you're going to produce less milk. And [by] using more land, you're going to displace more biodiversity likely or prevent rewilding in some sense. And when cows eat more grass, [...] the more fibrous diet the cows eat, the more methane is produced. There's been some studies that show that as much as four times as much methane is produced with grass-finished beef or more pasture for dairy versus the alternative."

"Solving Fresh Food Inventory Management" | CleanTechies

Guest: Johannes Olejnik | Head of Business Operations | Afresh
Time Saved: 52 Minutes

Selected Quote:

[24:27] JO: "In the US [...] about 40% of food that's produced at the farm [...] that's being wasted throughout the supply chain. [...] That roughly breaks down [to] 30% at the farm, 40% in the supply chain, so between distributors, transportation, and the retailers, and then 30% at the consumer level. [...] The biggest category is [the] distributors, transportation, and retailers, and so we're tackling that. [...] With our existing grocers, we have pretty good insight into how much we're reducing their waste and it's about 25%."
