Impact of FuelEU Maritime on solar PV for bulk carrier
This case study explores a 100 kWp solar PV system installed on the hatch covers of a handymax bulk carrier. Operating primarily in Northern Europe, the system offsets auxiliary engine load during idle periods, leading to estimated savings of ~$350,000 between 2025 and 2035. With a CAPEX of $100,000, the payback period is around three years. Most savings come from fuel reduction, with additional benefits from EU ETS and FuelEU compliance. The business case is most sensitive to engine efficiency (SFC) and fuel price.
How to decarbonize your ship - Inland Waterways + Solar PV
This is a case study on how to decarbonize an inland waterway ship with solar PV technology. Flexible solar PV panels from Wattlab are placed on an inland ship’s hatches in order to reduce fuel consumption while idling or moored. In some cases, the auxiliary generators can be switched off, resulting in an expected CO2 reduction of 26% - 100%.
Thailand builds a massive floating hydro-solar farm
Thailand is close to completing one the world's biggest hydro-floating solar hybrid farms on the surface of a dam, part of steps towards boosting renewable energy production after years of criticism for reliance on fossil fuels.
Making the Impossible Possible
This blog sketches a vision on how to convert the largest crane vessel in the world - Sleipnir - owned by Heerema Marine Contractors, to a zero-emission vessel. Several promising carbon reduction measures are combined which are technically viable and based on matured technology including electrification and BES, solar panels, synthetic fuels, CCS and possibly hydrogen combustion.
One of World’s Biggest Inland Floating Solar Systems begins construction in Singapore
Solar PV is integrated with the local water treatment system on Tengeh Reservoir in Singapore, offsetting 6% of its annual energy needs for 25 years.
