🔋🌍 Why Grid Flexibility Is the Key to a 100% Renewable Future 🌍🔋
Welcome back to the Climate Confident podcast! In this episode, I sit down with Anders Lindberg, President of Wärtsilä Energy, to tackle one of the biggest challenges in the energy transition—grid flexibility.
Renewables like solar and wind are now cheaper than ever, but integrating them into our energy systems isn’t as simple as it sounds. Without the right balancing technologies, countries risk energy curtailment, rising costs, and prolonged fossil fuel dependency. Anders explains how Wärtsilä’s grid-balancing engines and battery storage solutions can cut billions in costs while accelerating the shift to clean energy.
💡 What You’ll Learn in This Episode:
✔️ Why flexibility is essential for renewable energy integration
✔️ How countries like Chile could save $17 billion with a balanced energy system
✔️ The future of green hydrogen and when it will realistically scale up
✔️ How smart policies and flexible infrastructure can reduce emissions and improve energy security
✔️ The role of natural gas as a transitional fuel and Wärtsilä’s hydrogen-ready solutions
🌱 Whether you’re an energy professional, policymaker, or climate-conscious citizen, this conversation will give you practical insights into building a sustainable, reliable, and cost-effective energy system.

![How Rotor Sails Are Cutting Shipping Emissions by 50% | Norsepower CEO Heikki Pöntynen
Can shipping cut fuel use by 50%—today?
Norsepower’s modern rotor sails are already slashing fuel burn and CO₂ emissions on real-world voyages. In this episode of Climate Confident, CEO Heikki Pöntynen reveals how this century-old idea, re-engineered with modern tech, is transforming maritime decarbonisation—with up to 50% savings on some routes.
Watch to discover the Magnus effect in action, why IMO regulations have supercharged adoption, and how wind power is working alongside biofuels and electric ships to help hit net zero by 2050.
Can the shipping industry slash fuel use by up to 50% without waiting decades for new fuels?
In this episode of Climate Confident, I speak with Heikki Pöntynen, CEO of Finnish cleantech leader Norsepower, about how modern rotor sails are transforming maritime decarbonisation.
We unpack how Norsepower has revived the Flettner rotor – a century-old wind propulsion technology – and turned it into a scalable solution already cutting CO₂ emissions by 5–25% on most routes, with some transatlantic crossings aiming for 50% savings.
Heikki explains:
The Magnus effect that powers rotor sails
How AI-driven automation maximises efficiency
Why stricter IMO regulations have cut payback times to as little as one year
The booming market for retrofit solutions and “rotor sail ready” ships
How wind propulsion complements biofuels and electric vessels
With 26,000 tonnes of CO₂ saved to date, this isn’t a concept – it’s a proven, operational technology reshaping the future of sustainable shipping.
If you care about net zero shipping by 2050, maritime innovation, or practical climate solutions that work today, this conversation is essential listening.
