- Reduction of emissions is a key and challenging target. The largest emissions reduction impact will come from alternative clean fuel, that today is not available at scale and cost to be widely used.
- Market volatility in offshore wind impacted by economic and policy conditions.
- Project economics remain a key barrier to the pace of development in floating wind.
