The Yuldong-With-U complex in South Korea's Ulsan received 100% of heat and electricity from hydrogen fuel cell for a month.
The world’s first “hydrogen apartment” block has been unveiled in Ulsan, South Korea. The 437-household Yuldong-With-U complex gets 100% of heat and electricity from hydrogen fuel cells. The process has now run for a month and now the city will soon make its decision to price heat and power generated by the hydrogen.
In June, the Yuldong-With-U apartments generated 840MWh of power, which in conventional utility bills would have cost 150 million won .heat and power with reduced environmental impact. The method is claimed to be the most cost-effective compared to other process. The three container sized fuel cells, placed at the complex’s rooftop, generated 1.31 megawatts of electricity from 51 kgs of hydrogen per hour. This is enough to supply a month of electricity to four person households every hour.that has a 40-ton capacity. Then, heated water reaches temperatures upto 70 C and then piped directly into homes for heating, ensuring efficient use of all energy produced, reported Fuel cells have several benefits over conventional combustion-based technologies currently used in many power plants and vehicles. Fuel cells can operate at higher efficiencies than combustion engines and can convert the chemical energy in the fuel directly to electrical energy with efficiencies capable of exceeding 60%, according to US Department of Energy. Fuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes—a negative electrode and a positive electrode —sandwiched around an electrolyte, said theA fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode. In a hydrogen fuel cell, a catalyst at the anode separates hydrogen molecules into protons and electrons, which take different paths to the cathode. The electrons go through an external circuit, creating a flow of electricity. The protons migrate through the electrolyte to the cathode, where they unite with oxygen and the electrons to produce water and heat.An official from the Ulsan City maintained that there are plans to amend the Electricity Business Act in the country to give residents direct access to cost-effective electricity. However, due to regulatory issues, the hydrogen-generated electricity is currently sold to the Korea Electric Power Corporation, according toThe plan is to entirely realize the vision of 100% carbon neutral residential complex for eco-friendly living in urban environments.Prabhat, an alumnus of the Indian Institute of Mass Communication, is a tech and defense journalist.
