The aquatic market has enthusiastic decarbonization objectives, however the gas change called for to reach them will certainly not happen over night. The following action in the shift will likely be methanol, which– if generated from eco-friendly eco-friendly resources– will certainly bring the market to a degree of carbon nonpartisanship. At Alfa Laval, the innovations to allow that action remain in fast advancement.

On the reducing side of gas supply as well as burning

As a low-flashpoint gas, methanol postures substantial difficulties that call for a brand-new strategy to sustain supply. Having blazed a trail in gas line options for conventional gas, Alfa Laval has actually additionally gone to the leading edge with methanol, partnering with male Energy Solutions to establish a low-flashpoint supply system (LFSS) for ME-LGIM two-stroke engines.

The Alfa Laval FCM Methanol has actually currently gotten to greater than 100,000 hrs of procedure, as well as the option has actually been better created to satisfy the added demands of methanol-fuelled four-stroke engines as well as Alfa Laval Aalborg central heating boilers.

“Shipowners will save space and energy by using the same LFSS for the main engine, auxiliary engines and boilers fired with methanol,” claims Roberto Comelli,Business Manager Fuel Conditioning Systems “We can engineer one FCM Methanol system to handle the process parameters of multiple methane consumers, with automation that meets all their different needs.”

“When it comes to Aalborg boilers, which are prepared to work with methanol through our MultiFlame burner concept, the FCM Methanol ensures the correct fuel parameters,” claims Lars Skytte Jørgensen, Head of Technology Development,Energy Solutions “What remains is to fine-tune methanol combustion for maximum boiler efficiency, which is work that’s already in progress in full-scale testing at the Alfa Laval Test & Training Centre.”

Switching to methanol influences the power equilibrium

Handling as well as igniting methanol, nevertheless, will certainly be just one side of the methanol formula. Because methanol has much less power than conventional gas, it will certainly additionally be needed to reconsider power usage on methanol-fuelled vessels. Alfa Laval as well as companions are creating high-temperature proton exchange membrane layer (HTPEM) complete cells to supplement power manufacturing, however a brand-new strategy to existing power resources will certainly additionally be required.

“Waste heat recovery, which is usually overlooked on today’s vessels, will be a key component of tomorrow’s methanol operations,” claims Jørgensen. “There will be less demand for steam on board, but the heat energy will need to be applied in other ways. Due to methanol’s lower energy content and higher price, shipowners will want to turn every bit of the energy released into either mechanical or electrical power.”

Integrated options to onboard power demands

Alfa Laval is resolving this broader power image with both existing as well as brand-new options. The Alfa Laval Aalborg Micro, for instance, is currently a reputable exhaust gas central heating boiler. Connected to a terminated central heating boiler, it will certainly include heavy steam to a common heavy steam drum, consequently decreasing methanol intake by the heater. But it will certainly additionally be feasible to integrate with a plate warmth exchanger as well as the Alfa Laval E-PowerPack, a brand-new option based upon the Organic Rankine Cycle (ORC).

“ORC technology can generate electricity from any heat source on board, however small,” claims Jørgensen. “By using the Aalborg Micro to produce hot water, rather than steam, shipowners will have a medium that’s easily converted into additional power. Along with the fuel cells in development, ORC technology will help vessels maintain their energy balance after switching to methanol.”

Supporting the style of methanol-fuelled vessels

Alfa Laval’s methanol options remain to establish, however they are currently having an influence in method. The FCM Methanol, the Aalborg Micro as well as a variety of warmth exchangers for methanol have actually long been confirmed mixed-up. Moreover, Alfa Laval is helping leading shipowners in the style of methanol-fuelled vessels.

“Many shipowners are actively exploring the implementation of methanol, and Alfa Laval can be a strong sparring partner in that process,” claims Jørgensen.“In addition to our technologies themselves, we have a wealth of knowledge about methanol’s behaviour, acquired through our extensive testing. We welcome collaboration with customers, research partners and other technology suppliers, because the transition to methanol is a journey the industry must make together.”
