Analysis on use of hydrogen to gasoline Malta’s transportation


Aug 30, 2022

Transportation, one of many pillars of our society, is essential for Malta’s financial and societal existence. Because the world turns away from hydrocarbons and in the direction of different power, we push to hunt the electrification of the transport community.

Probably the most direct method to attain that is logically via using electrical automobiles. As a rustic, we’ve began to introduce EVs in each the business and private transportation networks with the assistance of robust authorities incentives.

Whereas such a route is certainly probably the most easy one in the direction of electrification, it nonetheless poses its personal set of challenges, together with the need of establishing adequate charging factors all through the island.

For an urbanised nation resembling Malta, having adequate charging factors, particularly when contemplating resi­dents residing within the village core and residences, is an costly problem.

Electrical automobiles additionally current novel challenges such because the recycling or disposal of batteries at their finish of life, tackling lithium-ion battery fires, particularly with automobiles parked inside garages, and the impact on the low-voltage community from a number of distributed charging factors unfold across the community itself.

An answer the MCAST Institute of Engineering and Transport is actively evaluating is to make use of hydrogen, the lightest and most plentiful of the weather, as gasoline. The phrase hydrogen is derived from the 2 Greek phrases ‘hydro’ and ‘genes’, which imply ‘water forming’; and it’s this water-forming means, when mixed with oxygen, that makes hydrogen key for its use within the electrification of transport.

Electric vehicles pose a number of challenges, including the number of charging points available and their effect on the low-voltage network.

By using what is called a gasoline cell, hydrogen from the gasoline tank is mixed with oxygen from the ambiance to supply electrical energy, which in flip drives the electrical motor. A hydrogen-fuelled automobile would emit solely water from its tailpipe, thereby having no influence on the setting.

Researchers from the Institute of Engineering and Trans­­port will likely be conducting detailed technical analysis on this area and in addition into the environment friendly manufacturing of hydrogen from water. It is very important examine the feasibility of utilizing off-the-shelf merchandise to supply hydrogen in situ via the electrolysis of water, the place hydrogen and oxygen are produced by splitting water molecules by way of an electrical present.

The principle benefit of a hydrogen-fuelled automobile system over an electrical vehicle-based system is that hydrogen will be produced at a small variety of gasoline stations instantly related to the 11kV community reasonably than having 1000’s of electrical automobiles being charged everywhere in the low-voltage grid.

This could load the grid in a way more managed manner, thereby avoiding the chances of low voltages and grid overloads at specific factors of the LV overhead line and feeder cable community.

The usage of inexperienced hydrogen may imply that our transport system would lastly be completely free from using hydrocarbons, with {the electrical} power wanted to supply the hydrogen coming instantly from different power sources resembling floating photovoltaic programs.

Hydrogen-powered automobiles utilise established techno­logy, with massive car producers providing hydrogen-fuelled automobiles at costs matching these of EVs

That is one other space being pioneered by the MCAST Institute of Engineering and Transport, with an precise floating PV system having been deployed by MCAST and its trade companions round 5 years in the past.

With a hydrogen-fuelled automobile, customers would additionally not want to attend for his or her automobile to cost over a lot of hours however can simply prime up their tank with hydrogen at a gasoline station. This is a vital side that may assist persuade customers to vary their automobile from hydrocarbon-fuelled to hydrogen-fuelled automobiles since customers accustomed to going to the gasoline station for top-up wouldn’t want to vary their habits.

Whereas a system utilizing hydrogen would nonetheless have its inherent issues of safety, one must level out that hydrogen-powered automobiles utilise established techno­logy, with massive car producers providing hydrogen-fuelled automobiles at costs matching these of EVs.

For some, hydrogen evokes visions of the Graf Zeppelin, with hydrogen exploding when reacted with oxygen in an uncontrolled manner. Producers have studied such points and elegantly mitigated this hazard via using particular crashproof gasoline tanks produced from composite supplies. It might subsequently properly be the case that hydrogen-powered automobiles wouldn’t be any extra harmful than automobiles that utilise petrol or battery-powered, each of which have well-known issues of safety too.

Even in case of an accident, within the unlikely state of affairs {that a} hydrogen leak happens, hydrogen, being the lightest of the weather, would rapidly stand up via the ambiance and dissipate. After all, rather more analysis is required to determine the viability of a hydrogen-based transport community for the Maltese islands.

This is likely one of the many areas wherein the MCAST Institute of Engineering and Transport is main Malta’s technological development – by coaching engineers, mechanics, technicians and technologists of tomorrow, via which our society can prosper in concord with the setting.

Stephen Sammut is the director of the Institute of Engineering and Transport at MCAST.
