What does it take for a lifelong nuclear skeptic to become the CFO of a nuclear company?
Keith Zakheim talks with X-energy CFO Daniel Gross about nuclear energy's shift from niche to mainstream infrastructure investment. A self-described former nuclear skeptic, Gross explains the safety science behind advanced reactors, his path through GE Capital, Goldman Sachs, and Amazon's Climate Pledge Fund, and what it will take to make nuclear as routine to finance as wind and solar. Holding up X-energy's ceramic pebble, he says, "good luck trying to get plutonium out of that." What can decades of financing wind and solar teach nuclear now? For energy and real estate audiences, this conversation gets specific about risk and safety.
Daniel Gross is Chief Financial Officer of X-energy, an advanced nuclear reactor company based in Maryland. His career in energy finance spans three decades, beginning at GE Capital's energy financial services business, followed by private equity and venture capital investing at Goldman Sachs' Special Situations Group. In 2021, Gross joined Amazon to co-head the Climate Pledge Fund, leading Amazon's investment in X-energy before becoming its CFO in late 2025. A longtime professor of clean energy finance, Gross holds degrees from Yale's School of Management and School of the Environment.

Why do the most sustainable products often carry a price premium — and can that ever change? Vivi Hollertt leads global sustainability strategy for Nouryon, the specialty chemicals maker spun off from AkzoNobel. On this episode, she explains why 96% of everyday products, from EVs to pharmaceuticals, trace back to chemistry, and why her team treats sustainability as a growth lever, not an ideology. "It's truly foundational for growth," she says, tying safer, biodegradable, low-carbon products directly to revenue and cost savings. But can sustainable products shed their price premium? Hollertt says closing that gap depends on scale, feedstock availability, and staying close to customers.
Vivi Hollertt leads global sustainability strategy for Nouryon and chairs its sustainability network, setting direction across climate, circularity, safety, and social performance. She began in communications, with roles at Heineken and Fleishman-Hillard, before joining AkzoNobel. When the specialty chemicals division became Nouryon after its 2018 sale to the Carlyle Group, she led carve-out communications and the new company's launch. Nouryon's chairman and CEO then asked her to take on sustainability, too. With no sustainability background, she completed an eight-week Cambridge course and has since moved fully into leading the function.

What if the biggest barrier to the energy transition isn't generation or demand — but the invisible infrastructure layer connecting them?
While most conversations about the energy transition focus on generation and demand, Lisa argues the real story is the invisible layer underneath: metering, data, and real-time connectivity. As electricity demand grows twice as fast as total energy demand — driven by EVs, data centers, and electrification everywhere — that backbone becomes non-negotiable. "When you put intelligence into the grid, it now can respond," she says. Extreme weather has raised public awareness of utility challenges in a way that little else has, creating what Lisa sees as the right conditions for real, scalable solutions to finally take hold.
Lisa Magnuson is a marketing and communications leader with deep expertise in energy infrastructure and utility technology. She began her career at Apple and NeXT before joining Silver Spring Networks as the company's first marketing hire, rising over 14-15 years to VP of Marketing and staying through a successful IPO. She then moved to PG&E — one of Silver Spring's largest customers — where she experienced firsthand the operational and communications challenges utilities face. She subsequently held roles at Bozilla and Bloom Energy before partnering with Landis+Gyr on a rebranding initiative, where she now focuses on the company's transformation as a global leader in grid-edge intelligence.

The data says we're making real progress on climate. So why does the conversation still feel like we're losing, and what does it mean to finally separate the signal from the noise?
Autodesk's software sits upstream in that process, shaping choices before ground is ever broken in industries responsible for roughly 40% of global emissions. "Sustainability cannot be a sidecar," Speicher says. It has to be embedded in the tools people use every day, making it everyone's job rather than one team's report. He also makes the case for reading the data honestly: 40% of global electricity now comes from renewables and nuclear, 43 countries have peak emissions behind them, and $2.3 trillion was invested in the energy transition in 2025. Are you building your strategy around the signals — or the noise?
Joe Speicher is Chief Sustainability Officer at Autodesk, where he leads global ESG strategy and works to embed carbon intelligence across the tools used by architects, engineers, contractors, and asset operators — industries collectively responsible for roughly 40% of global emissions. His path to the role was anything but direct: he began his career in finance at Deutsche Bank, served in the Peace Corps in the Philippines, and spent years working at the intersection of impact investing and corporate philanthropy before becoming Autodesk's CSO. That cross-sector background — finance, development, technology — shapes how he approaches sustainability as a strategic business function rather than a compliance obligation, focused on translating climate risk into decisions that drive measurable resilience and performance.
In This Episode:
(00:00) Joe Speicher’s unconventional path to climate leadership
(03:26) From Deutsche Bank and Peace Corps to leading Autodesk's sustainability strategy
(06:41) Why a finance and development background sharpens climate decision-making
(09:20) Reading the real signals: global emissions progress and the economics driving change
(12:05) Moving from commitments to action: embedding carbon intelligence into daily workflows
(14:11) Climate adaptation, wildfire recovery, and the CSO as strategic operator

What would it take to fit a geothermal system into a 125-year-old Manhattan co-op — and what happens when you actually do it?
Mike Richter spent two decades as one of the NHL's elite goaltenders, winning a Stanley Cup with the New York Rangers. Now, as President of Brightcore Energy, he's applying the same discipline and focus to decarbonizing commercial buildings. On this episode of Age of Adoption, Richter breaks down why geothermal heating and cooling — long considered niche and prohibitively expensive — is finally hitting its stride. "If I'm a competitor of yours and my energy costs are 40 to 50% lower than yours, I'm eating your lunch," he says. Brightcore's turnkey model — integrating design, drilling, financing, and a 10-year performance guarantee — removes the friction that has kept geothermal on the sidelines for decades. Drawing on lessons from Scandinavia, where geothermal penetration tops 25% compared to less than 1% in North America, Richter argues the technology is commercially proven and deployment-ready.
Mike Richter is President of Brightcore Energy, a turnkey clean energy firm serving commercial, institutional, and government clients across geothermal, solar, and energy efficiency solutions. Before entering the energy sector, Richter was one of the NHL's premier goaltenders for two decades, earning a Stanley Cup championship with the New York Rangers and representing the United States in multiple Olympic Games. After retiring from professional hockey, he pursued undergraduate studies and coursework at Yale's School of Forestry, developing a foundation in environmental policy and resource economics. He joined Riverkeeper's board before moving into clean energy finance, ultimately joining Brightcore in 2016. Richter brings a rare combination of competitive discipline, academic grounding, and business acumen to one of the most consequential challenges in building decarbonization.
In This Episode:
(00:00) Mike Richter, Stanley Cup goalie turned energy leader
(03:50) Richter's career path from hockey to Yale and environmental advocacy
(08:39) How Brightcore Energy was founded and why geothermal was chosen
(14:24) Brightcore's age of adoption story: lighting, solar, and geothermal scale-up
(21:30) Economics of geothermal: cost, scale, and competitive advantage explained
(24:28) Host wraps with why adoption is now economics, not just virtue
