At the intersection of these lanes is a place where ideas on finance, technology and policy are shared and debated. That intersection is Interchange Recharged. Your host is Sylvia Leyva Martinez, principal analyst and research director at Wood Mackenzie. When Sylvia isn't tracking the technologies and markets driving the build-out of renewable power, she's speaking with visionaries, entrepreneurs, policy-makers and energy analysts to explore the newest developments in renewable technology, explain the ideas on global energy policy that could accelerate the energy transition, and identify new funding and financial models that could solve the biggest challenges we face on the way to net zero. Sylvia and her guests bring you data and forecasts on clean technology, climate science, and offer predictions on the build out of utility-scale projects and the future of green finance. What does the surge in data-centre demand mean for the grid, and who pays for it? What's happening in global EV adoption and development? What's the forecast for solar, one of the major succ…","last_synced_at":"2026-09-16T02:19:58.805362+00:00","page_url":"https://stenobird.com/podcast/interchange-recharged-1117793"},"episode":{"title":"Beyond combustion: Long Island's first hydrogen-powered linear generator and the fuel-flexible answer to the dispatchable emissions-free resource problem","slug":"beyond-combustion-long-island-s-first-hydrogen-powered-linear-generator-and-the-fuel-flexible-answer-to-the-dispatchable-emissions-free-resource-problem","published_at":"2026-05-05T11:00:00+00:00","page_url":"https://stenobird.com/podcast/interchange-recharged-1117793/beyond-combustion-long-island-s-first-hydrogen-powered-linear-generator-and-the-fuel-flexible-answer-to-the-dispatchable-emissions-free-resource-problem","show_page_url":"https://stenobird.com/podcast/interchange-recharged-1117793","url":"https://dts.podtrac.com/redirect.mp3/rss.art19.com/episodes/06c89e41-0ec6-4e06-ba8b-c52d51cd0ee2.mp3?rss_browser=BAhJIg90cmFuc2NyaWJyBjoGRVQ%3D--952c5701c84ad333c69d5faa668f8177091704f0","audio_url":"https://dts.podtrac.com/redirect.mp3/rss.art19.com/episodes/06c89e41-0ec6-4e06-ba8b-c52d51cd0ee2.mp3?rss_browser=BAhJIg90cmFuc2NyaWJyBjoGRVQ%3D--952c5701c84ad333c69d5faa668f8177091704f0","summary":"Utilities are under pressure to deliver generation that is dispatchable, affordable, and clean enough to satisfy increasingly stringent environmental rules, notoriously hard to do in one asset. As renewables grow, the gas turbines and engines that have historically filled the gap come with a NOx problem, a CO2 problem, or both. Hydrogen offers a path through, but the supply isn't there yet. So what do you build today? Host Bridget van Dorsten is joined by Shannon Miller, CEO of Mainspring Energy, and Will Hazelip of National Grid Ventures, to dig into a technology most listeners haven't heard of and the first commercial hydrogen-powered deployment of it. Mainspring's 250-kilowatt linear generator is being installed at National Grid's 1,500 MW North Port facility on Long Island, in partnership with NYSERDA, the Long Island Power Authority, and Stony Brook University. Shannon explains how Mainspring redesigned the generator using the power electronics that drive solar inverters, batteries and EVs, replacing mechanical systems with software, eliminating the flame, and operating at temperatures low enough to take NOx out of the equation. An adaptive pressure cycle, software-controlled in real time, runs the same hardware on hydrogen, compressed natural gas, biogas, propane or blends, with no hardware change. The 250 kW form factor matters too: efficiency holds across the full load range, fleet redundancy replaces single-asset reliability risk, and deployment is a concrete pad plus electrical and fuel hookups rather than a multi-year build. Will frames the project against the regulatory backdrop. Long Island sits in a non-attainment zone for NOx, and New York's path to a carbon-free grid requires what the state calls a dispatchable emissions-free resource. The unit will run…","meta_description":"Utilities are under pressure to deliver generation that is dispatchable, affordable, and clean enough to satisfy increasingly stringent environmental rule…","key_points":[],"chapters":[],"topics":[],"duration_seconds":2383,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/interchange-recharged-1117793/episodes/beyond-combustion-long-island-s-first-hydrogen-powered-linear-generator-and-the-fuel-flexible-answer-to-the-dispatchable-emissions-free-resource-problem/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/interchange-recharged-1117793/beyond-combustion-long-island-s-first-hydrogen-powered-linear-generator-and-the-fuel-flexible-answer-to-the-dispatchable-emissions-free-resource-problem.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
