2 MAR. 2026 · In this episode of Big Ideas Only, Mikkel Svold reconnects with Dr. Benjamin Jones, Chief Conservation Officer and co-founder of Project Seagrass, to explore what happens when seagrass theory meets real-world conservation.
Moving beyond the science of carbon capture and marine ecology, this conversation digs into the practical challenges of protecting an ecosystem that most people have never thought about. Benjamin shares stories from fishing communities in Indonesia and Florida, explains why government departments struggle to coordinate land and sea management, and describes how citizen science and political engagement have become surprisingly effective tools. The discussion reveals that saving seagrass often has little to do with planting seagrass — and everything to do with what happens on shore.
In this episode, you'll learn about:
- Why 13.5 million people living below the poverty line depend directly on seagrass for their daily food
- How seagrass meadows store carbon for up to 200,000 years — and release it rapidly when destroyed
- The governance gap between marine and terrestrial management that makes coastal protection so difficult
- Why restoring seagrass sometimes means planting fruit trees along riverbanks instead
- How Wales created the world's first National Seagrass Action Plan through cross-party dialogue
- What everyday actions (diet, driving, citizen science) actually connect to seagrass health

2 MAR. 2026 · In this episode of Big Ideas Only, host Mikkel Svold sits down with Kasper Elgetti Brodersen, Associate Professor at Roskilde University, to explore the science behind one of our most overlooked coastal ecosystems: seagrass meadows. What looks like an annoyance when it brushes against your legs while swimming turns out to be a biological powerhouse — nursery grounds for fish, carbon storage systems, and water quality filters all in one. Kasper explains how seagrass interacts with sediments and bacteria, why nutrient runoff from farmland is suffocating Danish fjords, and the surprising discovery that stressed seagrass can flip from climate helper to greenhouse gas emitter. The conversation covers what makes restoration so difficult, why seeds might be better than transplants, and what still needs solving before we can successfully garden the sea.
In this episode, you'll learn about:
- Why seagrass provides four times the ecosystem services of coral reefs (measured in economic value)
- How seagrass creates its own oxygen supply to survive in toxic, oxygen-free sediments
- The mechanism that turns nutrient pollution into plant-killing hydrogen sulfide
- Why stressed seagrass meadows can start producing methane and nitrous oxide instead of capturing carbon
- What makes restoration in Danish fjords so challenging — and why seeds might work better than transplants
- The bacterial partnerships happening underground that help seagrass access nitrogen

20 OCT. 2025 · What happens when wind and solar deliver more power than the grid can handle and batteries aren’t the answer?
In this episode of Big Ideas Only, host Mikkel Svold sits down with Pat Han, Technical Director at Skovgaard Energy, the company behind what is called the world’s first dynamic Power-to-X (PtX) ammonia plant.
Pat explains how “dynamic” PtX rides the ups and downs of wind and solar, turning excess electricity into ammonia. The ammonia process can start and stop quickly, that’s why ammonia is a strong first “X”, and how the sector coupling can turn rural areas into thriving energy hubs.
In this episode, you’ll learn about:1. What “dynamic” PtX means and why flexibility is the missing piece for high-renewables grids.
2. Why hydrogen-to-ammonia enables storage and transport.
3. How the process works from water to hydrogen plus nitrogen to ammonia.
4. How PtX is a flexible consumer that balances variability and prevents curtailment.
5. Why market design, ESG, and value-chain planning matter more than tech.
6. The social benefits with a PtX plant, such as jobs, industrial neighbors and revitalizing rural regions.
7. How good local cases unlock permits, public support and future regulation.
Episode content:
01:20 What is Power-to-X?
08:31 Limits of batteries for grid-scale storage
10:35 Why ammonia?

13 OCT. 2025 · Fusion has long carried the reputation of being “30 years away”. Forever on the horizon but never quite arriving. That perception may finally be changing.
In this episode of Big Ideas Only, host Mikkel Svold is joined once again by Søren Bang-Korsholm, senior scientist at the Department of Physics at DTU. This time, the focus is on the practical future of fusion energy: what private companies are doing differently, how huge global projects like ITER fit into the picture, and what role fusion could play in the broader energy transition.
From billionaire-backed startups to the promise of grid-ready plants, Mikkel and Søren explore whether fusion can move beyond test facilities and become a true energy source for the 21st century.
In this episode, you'll learn about:
1. Why private investment is accelerating fusion research.
2. The scale and goals of the ITER project—the world’s biggest science collaboration.
3. How fusion could integrate into existing grids and even replace coal plants directly.
4. The role of fusion as a clean, reliable base load alongside renewables.
5. Potential use cases beyond electricity, including hydrogen production and desalination.
6. The biggest technical hurdles still standing in the way.

13 MAY. 2025 · What if we could power the world the same way the sun does? No carbon, no meltdown risks – just clean energy from smashing atoms together.
In this episode, I sit down with Søren Bang Korsholm, Senior Scientist at the Technical University of Denmark, to talk about fusion energy. You’ve probably heard it called the “holy grail” of power, but—weird metaphors aside—what does that actually mean? And are we any closer to making it work outside a lab?
We cover how a tiny bit of fusion fuel could keep your lights on for a lifetime, why plasma is such a pain to control, and whether this whole thing is still sci-fi or finally getting real.
If you like science, big ideas, or just want your energy bill to stop looking like your rent, give it a listen.
