Lloyd’s Register (LR) has awarded an approval in principle (AiP) to BeHydro for the development of a hydrogen-powered dual-fuel engine with a capacity to 2.6 MW, the first units of which will be installed in a tug
The AiP was granted to BeHydro, a joint venture between Compagnie Maritime Belge (CMB) and engine developer Anglo Belgian Corporation (ABC), following a preliminary review of the engine documentation.
The AiP will allow development of the engine to move forward.
LR used existing rules as appropriate -- and a risk-based approach where rules are not available -- to ensure safety standards are met while moving forward with novel technologies.
Expectations are that the new dual fuel engine, launched in September 2020, offers the opportunity to reduce CO2 emissions by up to 85%, and fuel flexibility when hydrogen is not available. Availability of the medium-speed engine technology is essential for hydrogen to advance as a clean energy, alternative fuel.
The first two BeHydro marine engines, 2 MW primer movers, will be installed in a 65-tonne bollard pull, hydrogen-powered tug, Hydrotug, for the Port of Antwerp.
BeHydro is planning to develop dual-fuel engines of up to 10 MW, and a mono-fuel hydrogen engine which will reduce CO2 emissions by 100%. At the time of the launch, BeHydro anticipated the release of a zero-emission engine with spark ignition that will burn only hydrogen by Q2 2021. The hydrogen fuel engine will be available in the power range of 1 MW to 2.7 MW, the company said.
