Evan Hynes is the CEO and co-founder of ClimateBase, the leading job platform for climate. Launched in 2020, ClimateBase has scaled incredibly fast with over 250,000 monthly users, over 100,000 subscribers to its climate newsletter, and more than 7,000 participants to the ClimateTech week it recently organized in San Francisco. And all of this growth with only 7 full-time employees and ~$300K in angel investor funding. In this episode, we talk with Evan about: His early experiences in community-building as an undergrad at UC Barbara and then at a YC Combinator startup offering software engine ..read more

Raphael Declercq is the CEO of PowerFlex, a 300 people strong company based in San Diego, California with the mission to help businesses transition to distributed renewables and electrified transportation. Launched as a subsidiary of EDF - the French energy giant operating over 30+ nuclear power plants - PowerFlex has quickly become the 2nd largest installer of rooftop solar for commercial buildings and the 4th largest EV installer in the US. With $100M raised last year, PowerFlex aims to accelerate the transition of commercial customers to clean energy and to continue to invest in its unique ..read more

Olivier Reinaud is Co-Founder & Managing Director at NetZero, a startup bringing carbon removal at scale in the tropics with biochar. Launched in 2021 with a diverse founding team, including the climatologist Jean Jouzel (IPCC vice chair), NetZero has rapidly demonstrated its technology in Cameroon and Brazil and has been selected in the prestigious Musk Foundation’s X Prize for Carbon Removal. With $12M raised recently to scale up operations, Net Zero aims to remove 2 million tons of CO2 with biochar by 2030 with a mutually beneficial partnership between all biochar stakeholders: Agricul ..read more

Sebastian Berning is the co-founder & CEO of Instagrid, a startup aiming to replace combustion generators used for mobile power supply by clean portable batteries. These generators are used every time power supply is needed without an easy access to the grid: in food carts to cook, on construction sites to run jackhammers, at festivals for lighting & sound, and in countless other applications. While not getting much attention from regulators to date, these generators do pose massive health and climate problem by releasing huge quantities of air particulates, typically in dense urban ar ..read more

Alexis Normand is the Co-founder & CEO of Greenly, a carbon accounting and management platform enabling companies to measure and reduce their emissions Carbon accounting has grown from a niche practice only a few years ago to a widely adopted business practice with 18,700 public companies now disclosing their emissions By measuring their emissions, companies can then define climate targets with ~2,200 companies having set a net zero science-based target to date, a number that has grown exponentially over the last years Yet, much remains to be done with 17,000 public companies still failing ..read more

Alexia Akbay is the founder & CEO of Symbrosia, a startup producing a seaweed feed supplement for ruminants that can reduce their methane emissions by 90% Ruminent livestock (cows, beef, sheep, goat) are responsible for ~14% of total greenhouse gas emissions (~7Gt of CO2-eq). Enteric fermentation, which is part of the ruminant's digestive process, drives ~40% of these livestock emissions as methane - a highly potent gas with intense short-term warming effects With global livestock numbers on the rise in spite of the emergence of meat substitutes and milk alternatives, practical solutions l ..read more

Casey Handmer is the founder of Terraform Industries, a startup that produces synthetic fuels by combining CO2 captured from the air with renewable hydrogen. Fossil fuels are responsible for ~75% of anthropogenic emissions and we need to reduce their consumption as fast as possible. Yet, even under the most optimistic decarbonization scenario, natural gas and oil will still play an important role in our energy systems in 2030-40. Terraform aims to decarbonize this residual fuel consumption by producing synthetic fuels more cheaply than by drilling the Earth. In this episode, we talk with Casey ..read more

Hydrogen will play a pivotal role in abating 25% to 40% of US emissions in the so-called "hard-to-abate" sectors: long-distance transportation (aviation, shipping, trucking), industrial feedstock processes (ammonia, methanol, refining), long-duration energy storage, and as a heating fuel for commercial & industrial customers. Shawn Drost is the cofounder and CEO of Phoenix Hydrogen, a startup building the first commodity marketplace connecting all the players of the hydrogen value chain. To get to critical mass, Phoenix Hydrogen is building one of the largest underground storage facilities ..read more

Kathy Hannun is the co-founder and President of Dandelion Energy, the US leader in geothermal heat pumps for home heating and cooling. From an idea emerging at Google X in 2017, Dandelion Energy has now installed over 1,000 geothermal systems and raised a total of $60M. Building heating is a truly massive climate challenge with ~20% of emissions globally due to energy use in buildings, with most of this energy going to space heating (the rest going to power appliances primarily). In this episode, we talk with Kathy about: her early childhood and what drove her interest in climate how the Dand ..read more

Paul Gross is the co-founder and co-CEO of Remora, a carbon capture solution for heavy-duty trucks. Using work from Christina Reynold's PhD thesis at the University of Michigan (Remora other co-CEO), they created the company in 2020, joined Y Combinator and raised $5.5M to now be a 45 people strong company about to deploy their product at some of the largest American trucking companies. In this episode, we talk with Paul about: his early childhood and what drove his interest for climate how the Remora idea originated at Yale and how he assembled a dream team to get the project off the ground ..read more
