South Korea’s Hyundai subsidiary Rotem has just unveiled its vision for the future of main battle tanks for the Republic of Korea (ROK), hydrogen-powered powertrains.
The next version of ROK’s K-series battle tanks, the K3, will be powered by hydrogen fuel cells and feature other advanced tech to become one of the world’s most sophisticated tanks.
The new hydrogen-powered K3 has been developed in collaboration with Korea’s Agency for Defense Development and other national technology research institutions. Once operational, the tank is hoped to enter production as soon as 2040, making it the world’s first. READ MORE...
A hydrogen vehicle is a vehicle that uses hydrogen fuel for motive power. Hydrogen vehicles include hydrogen-fueled space rockets, as well as ships and aircraft. Power is generated by converting the chemical energy of hydrogen to mechanical energy, either by reacting hydrogen with oxygen in a fuel cell to power electric motors or, less commonly, by burning hydrogen in an internal combustion engine.
As of 2021, there are two models of hydrogen cars publicly available in select markets: the Toyota Mirai (2014–), which is the world's first mass-produced dedicated fuel cell electric vehicle (FCEV), and the Hyundai Nexo (2018–). There are also fuel cell buses. Hydrogen aircraft are not expected to carry many passengers long haul before the 2030s at the earliest.
As of 2019, 98% of hydrogen is produced by steam methane reforming, which emits carbon dioxide. It can be produced by electrolysis of water, or by thermochemical or pyrolytic means using renewable feedstocks, but the processes are currently expensive. Various technologies are being developed that aim to deliver costs low enough, and quantities great enough, to compete with hydrogen production using natural gas.
The benefits of hydrogen technology are long range on a single refuelling. The drawbacks of hydrogen use are high carbon emissions when hydrogen is produced from natural gas, capital cost burden, low energy content per unit volume at ambient conditions, production and compression of hydrogen, the investment required to build refuelling infrastructure around the world to dispense hydrogen, and transportation of hydrogen.
