Is renewable offshore in a crisis ?
Yes, the offshore renewable energy sector, particularly offshore wind, is facing significant challenges that could be considered a crisis in some regions. Here are some key issues:
1. Rising Costs and Inflation
The cost of materials such as steel, copper, and rare earth elements has increased, making offshore wind projects more expensive.
Higher interest rates have also raised financing costs for large-scale projects.
2. Project Cancellations and Delays
Several major offshore wind projects have been canceled or delayed, especially in the U.S. and Europe.

The use of hydrogen fuel in outboard engines faces several challenges. Hydrogen's low energy density by volume requires high-pressure storage tanks, adding weight and space constraints to small boats. Its highly flammable nature demands advanced safety measures, increasing costs. Hydrogen infrastructure, such as refueling stations, is limited, posing logistical hurdles for marine use. Additionally, adapting existing engine designs to efficiently burn hydrogen without compromising performance or durability requires significant research and development. The corrosive effects of hydrogen on materials and its compatibility with marine environments further complicate its adoption. Addressing these challenges is essential for hydrogen-powered outboards to become viable.
