The charge time for hydrogen fuel cell power units is extremely rapid, similar to that for conventional internal combustion engine (ICE) vehicles and markedly quicker in comparison tobattery-powered electric vehicles. With almost no emissions, hydrogen fuel cells do not release greenhouse gases, which means they do not have a carbon footprint while in use. Hydrogen fuel cells do not generate greenhouse gas emissions as for fossil fuel sources, thus reducing pollution and improving air quality as a result. The same goes for vehicles, where hydrogen fuel cells use 40-60% of the fuel’s energy while also offering a 50% reduction in fuel consumption. For example, a conventional combustion based power plant generates electricity at 33-35% efficiency compared to up to 65% for hydrogen fuel cells. This fuel efficiency allows for the production of more energy per pound of fuel. Hydrogen fuel cells are more efficient than many other energy sources, including many green energy solutions. These 4. Highly Efficient when Compared to Other Energy Sources High pressure gaseous and liquid hydrogen have around three times the gravimetric energy density (around 120MJ/kg) of diesel and LNG and a similar volumetric energy density to natural gas. Hydrogen has the highest energy content of any common fuel by weight. Hydrogen fuel cell technology provides a high-density source of energy with good energy efficiency. 3. More Powerful and Energy Efficient than Fossil Fuels HYDROGEN FUEL CELL UPGRADEProduction, storage and use of hydrogen will play an important role in driving further development of renewable energy, by balancing their intermittent supply modalities with the challenging end-user demands, avoiding the need for significant early investment to upgrade grid infrastructure. This shows that hydrogen fuel cells are a non-toxic fuel source and therefore superior in this way to coal, natural gas and nuclear power which are all either potentially dangerous or hard to obtain. In fact, NASA have even been working on using hydrogen as a resource with the water produced as a byproduct being used as drinking water for astronauts. Unlike biofuel or hydropower, hydrogen doesn’t require large areas of land to produce. Hydrogen fuel cells provide an inherently clean source of energy, with no adverse environmental impact during operation as the byproducts are simply heat and water. 2. Hydrogen is a Clean and Flexible Energy Source to support Zero-Carbon Energy Strategies Hydrogen is the most abundant element in the Universe and despite the challenges associated with its extraction from water, is a uniquely abundant and renewable source of energy,perfect for our future zero-carbon needs for combined heat and power supplies. Hydrogen fuel cell technology presents several advantages over other power sources, including: 1. What are The Advantages of Hydrogen Fuel Cells? for grid electricity, domestic and industrial heating and fuel for transportation).ĭebates continue regarding hydrogen fuel cells advantages and disadvantages, but despite current limitations, hydrogen is still an environmentally-friendly alternative to fossil fuels and can be used to provide flexible and high-density power and propulsion for a wide range of industrial plant and modes of transportation using hydrogen fuel cell technology. In order to produce a secure, resilient and decarbonised energy system, production and bulk storage of hydrogen will play an important role in balancing intermittent supply of energy from renewable energy sources with end-user demands (ie. However, as manufacturing capacity for more efficient and cost-effective electrolysers grows, it is expected that costs of production will fall markedly alongside roll-out of maturing renewable power generation technologies and capacity. Currently, the vast majority of global hydrogen production derives from fossil fuel sources (methane gas reforming) and will continue to do so for several decades. Green hydrogen produced from electrolysis (a high energy process) and renewable energy sources is a high cost option, which only accounts for around 5% of total H 2 production. There is also growing interest in hydrogen power as a uniquely clean energy source that can produce heat and whose only by-products are water. The reverse process of electrolysis, which produces ‘green’ hydrogen and oxygen from water, can use a range of renewable energy resources (wind, wave, solar) to produce hydrogen as a fuel for renewable power generation. Hydrogen fuel cells use hydrogen as a fuel in an electrochemical process that combines hydrogen and oxygen to produce electrical energy and water.
