In this episode, Aroon shares insights on why data center flexibility is critical to protecting energy affordability, grid reliability and the broader economy amidst the AI boom.

We were thrilled to speak with Brandon Corts, Senior Director of Product at Newlab — a venture platform accelerating the commercialization of critical technologies. Between early-stage VC funding and late-stage infrastructure capital, hard technology companies face a “valley of death” where many fail. This challenge is not new but it is intensifying. According to Sightline Climate, in 2024, there was a 10% drop in Series B deals, and it took over two years on average for companies to advance from Series A to Series B, up from 20 months in 2023. In the latest episode of the Wharton Current, Ian Miller and Lilly Chadwick sat down with Brandon to discuss Newlab’s venture platform and the creative pathways hard tech companies can follow to successfully overcome the valley of death.

For investors, taking sustainability seriously requires high-quality company-level data. That, in turn, requires standards that ensure companies across industries and economies are providing this kind of investor-useful data. We need accounting standards for sustainability reporting, just like what we have for financial reporting. Our guest this week is from the international body that's tackling this task. Elizabeth Seeger is a Wharton MBA alum and board member at the International Sustainability Standards Board (ISSB), a 14-member body within the world's standards-setter for accounting, the IFRS Foundation. The ISSB released this summer a pair of global baseline standards for sustainability and climate reporting. They're working with countries and international organizations around the world (G7, G20, central bank governors, and more) to drive global adoption. Listen to learn: -- How the ISSB is unifying the global maze of sustainability accounting standards -- How the board draws on financial reporting concepts in underpinning its sustainability reporting standards -- How sustainability reporting standards in public markets affect private markets. Bio: Elizabeth Seeger has over 20 years’ experience of standard-setting, investment and working on sustainability topics. She joined the ISSB from global investment firm KKR, where she served as Managing Director, Sustainable Investing, responsible for helping oversee the firm's consideration of sustainability matters throughout KKR’s investment process and part of KKR's Global Impact team. She also oversaw KKR’s public sustainability reporting efforts, including the development of SASB and TCFD-aligned reporting. Before joining KKR in 2009, she served as a project manager in the corporate partnerships programme (now known as EDF+Business) of Environmental Defence Fund. Elizabeth's comments represent her views and opinions and not those of the ISSB or the IFRS Foundation.

Adding renewables and batteries to our power grid cuts emissions and can lower costs. But it also makes grid stability a more complex affair. That's in part because these systems tend to have less "inertia" -- a byproduct of turbine rotation that helps insulate grids against fluctuations in supply and demand. The old models and heuristics for inertia management no longer apply, and grid operators compensate by running their systems more conservatively -- higher cost, and higher emissions. What's the alternative? Frederico Rauter is chief revenue officer at Reactive Technologies, a Series C startup with a pioneering new technology for precise inertia measurement. Frederico tells us: -- What inertia is, and how their technology improves upon the current tools for monitoring it -- Why utilities can be slow to adopt new technologies, and how they've developed their product with those obstacles in mind -- How he built a career before Reactive tackling innovation in large corporates (SNCF, Siemens) If you'd like to connect with Frederico or share your thoughts on this episode, please write to edmund.downie@princeton.edu.

How do you store a lot of zero-carbon energy for cheap? Justin Briggs and his co-founders at Antora Energy believe in a simple answer. Find a cheap and abundant material that can retain a lot of energy in a small volume -- and use zero-carbon electricity to get it really hot. That's the product that Antora Energy offers: thermal energy storage using blocks of solid carbon. They've raised $50mn in Series A funding as they target scaling their product, focusing on markets in industry. Justin sat down with Ned Downie and Shivani Shikha to talk about: -- Why the Antora team decided that thermal energy storage was such an appealing product to develop -- How they see their competitive edge against other thermal energy storage technologies for industrial decarbonization -- How centering their mission -- stopping climate change -- in raising funds made them more attractive to venture investors

Energy efficiency saves consumers money, and we need deep cuts in home energy use to reach our world’s net-zero goals. How can we get more homeowners to invest in it? That’s the question that drives Lauren Salz. She’s CEO and co-founder of Sealed, an energy and financial technology company that helps homeowners finance home improvements that save on energy costs and emissions too. Lauren tells us about what makes homeowners invest in energy efficiency(hint: it’s often not about money, and definitely not about climate!) and about how she and her co-founder have built Sealed to fit those motivations. She also walks through how she transitioned from consulting to starting a company and shares stories from her days as a surprisingly well-paid street musician in London.

In this episode, Ned Downie and Ellie McDonald chat with a founder from an area of climatetech that's only starting to get the attention it deserves -- adaptation. Guest Bessie Schwarz is co-founder and CEO of Floodbase, a company that provides near real-time data on flood mapping and flood risk for markets including parametric insurance, risk analysis, and disaster management. They announced a $12mn Series A in late January 2023 led by Lowercarbon Capital. Bessie talks about what Floodbase brings to insurance, risk, and disaster management markets; what it's like to go from being a community organizer to being a startup founder and climate tech; and how adaptation funding as a space has changed since she and her co-founders started working on this company a decade ago.

The market for carbon capture focuses on large-scale projects -- capture retrofits in heavy industry, say, or enormous facilities to suck carbon directly out of the air. But should we also be capturing carbon inside buildings? Our guest for this week says yes. Nick Martin is COO of Carbon Reform, a Delaware-based startup developing a modular retrofit device for commercial HVAC systems that scrubs both traditional indoor air pollutants and carbon dioxide. They raised $3mn in seed funding in fall 2022. We discuss with him how their module can save customers money on energy costs, how they're thinking about target markets, and why traditional carbon-capture policy incentives need tweaking to serve decentralized solutions like theirs.

Concrete is the most used material in the world after water -- but an indispensable input, cement, accounts for 8% of global carbon emissions. How do we slash cement's carbon footprint?
