24.09.2020 7 OPINION H ydrogen is increasingly becoming a focus area for aircra builders such as Airbus as the sector looks forward for zero-emissions flight. e avi- ation industry is under increasing pressure to adopt environmentally friendly technology. In fact, it is good to mention that Airbus wants to explore the concept of the world's first climate neutral, zero emission commercial flight. ey hope to put such aircraft in service by 2035 but naturally the success of these planes would require infrastructure at airports for hy- drogen transport and refuelling facilities to meet the demands of daily operations. Appropriate legislation will need to support this new sector. It would also need funding of the research and technology, digi- talisation and mechanisms that encourage the use of sustainable hydrogen fuel. Another innova- tion in zero emissions is fuel cell cars. is is no rocket science, we should not forget that hydro- gen technology is not new, but is tried and tested in a range of fields. By way of example, refin- eries today use large quantities of hydrogen as a process gas in the processing of crude oil. Pipelines and hydrogen storage have also been in operation for decades. How can we access the fuel - the answer is that hydrogen is not naturally occurring, but can be found in various other sub- stances, and can be extracted? Hydrogen can be generated from natural gas and biomass, and electrolysis using renewa- ble energies such as solar, wind or hydro-power generation. As hydrogen can be generated using methods suited to regional char- acteristics and climate, an ideal hydrogen cycle that does not rely on fossil fuel can be established in the future. Question is - are our town planners ready to embrace the challenge of fuel-cell cars? In a future mass transit solution, one may not forget the unique advantages for no emissions and cheaper fuel cell cars (when compared with more expensive electric vehicles). Needless to say, there is a changing landscape as regards modern transportation. Malta has seen various scientific stud- ies on how to introduce efficient mass transit solutions. ese present important opportunities for commuters, in a drive to sus- tain the green economy. Malta has just been offered millions in EU funds to be invested in future green projects and this is a unique chance to exploit their use. Recognising such opportu- nities, we read how on a global scale the automotive industry is investing billions in developing, manufacturing and bringing to market engines that are cleaner and more fuel efficient. Why is this forthwith concern in Malta to start reducing emissions and improving congestion prob- lems? is culminates from a rap- id growth in private cars which is partly the cause of enhanced affluence, cheap bank loans and the unpopularity of public trans- port. Close to 380,000 ageing vehicles (almost one for each resident - a good number being imported second-hand) clog the narrow streets during rush hours, thus rendering commut- ing a daily nightmare. Government is daringly allo- cating €700 million to upgrade the road networks and this is not a palliative but a bold decision to upgrade the frail infrastructure. Undoubtedly, the perfect solu- tion on how to best tackle our traffic congestion is not an easy one. Noble efforts have been made by Transport Malta to ex- empt electric cars from registra- tion tax and so far, the island has a number of charging bays (albe- it limited in number). At the moment, electric vehi- cles (EVs) are more expensive than conventional ones but EVs come with a variety of savings, like lower operating and mainte- nance costs - an advantage that their fossil fuel-powered coun- terparts don't have. On top of this, Transport Malta offers cash refunds when buying a new EV, while other countries have incentives and tax credits particularly geared for fleet com- panies. It is slowly becoming main- stream in Malta that EVs are ob- viously a practical choice since they provide ample torque such that at change of colour at traffic lights, you will be able to speed ahead in a sneaky way and no- body notices since the engine is so quiet. Technological advances in elec- tric mobility enable carmakers to offer an ever-expanding range of vehicles, which makes buyers spoilt for choice. As stated ear- lier, in Europe - public concerns about air quality and greenhouse gas emissions are growing. is concern is coupled with increasingly stringent EU emis- sions regulations and changing trends in car ownership has added increasing impetus to the automotive industry's commit- ment to produce cheaper ul- tra-low emission vehicles. It has led to a range of different solu- tions, including hybrid electric vehicles, plug-in hybrid electric vehicles, extended-range electric vehicles, and the introduction of zero-emission tailpipe vehicles such as battery electric vehicles (BEV) and hydrogen fuel cell electric vehicles. Ideally the price of the fu- el-powered vehicles falls. Many ask what are hydrogen and fuel cell cars? Are these safe and cheaper to use than electric models. e answer is that both electric and hydrogen technolo- gies come with their advantages and challenges. To start with, hydrogen is the most abundant element in the universe. It is itself renewable, and can also be produced using renewables such as wind and so- lar. It has been used safely and successfully in industrial pro- cesses for a number of years. In fact, a fuel cell stack is made up of a large number of individu- al cells. In each cell a chemical reaction takes place between hydrogen molecules (H2) and the oxygen (O2) present in the ambient air. is reaction produces both water (H2O) and an electric cur- rent. A number of electrons so gen- erated move from the negative to the positive electrode - thus generating electricity to drive the motors. In conclusion, as more atten- tion has turned to limiting global warming, the potential for hy- drogen to enable the necessary energy transformation has taken a pivotal role. As a fuel, hydrogen has distinct benefits when compared to elec- tric models, including fast refu- elling and high energy density. Another practical advantage is that hydrogen refuelling infra- structure could also be readily scaled up without the need in Malta to invest in expensive electricity distribution upgrades at EneMalta. e technology of the future is with us, as fuel cell vehicles are particularly suited for applica- tions with longer-range journeys (in between refuelling), ideal for aircraft which in the future can roam over our island with zero emissions. Once Covid 19, is tamed with the circulation of an effective vaccine, our frail tourist industry will certainly pick up. With the help of new technol- ogy, we can welcome the arrival of millions with a difference that new technology in cars, cruise ships and aircraft will lead to considerably lower emissions.
