수소연료전지 – 한국 신재생에너지 기대.
The landmark Paris Agreement on Climate Change entered result last month, with nearly two-hundred nations guaranteeing to fight worldwide warming.
That implies renewable resource sources, such as solar and wind power, are significantly coming forward.
For Korea, one of the fastest growing renewables is hydrogen fuel cell innovation.
Korea produces nearly half of the world’s fuel cell power and is relying on its advancement to assist it reach its emissions targets. Betting on fuel cell: our news function tonight with Kwon JAngho.
The battle versus environment modification is on.
With the Paris accord now in result, Korea has actually vowed to do its part, by decreasing its carbon emissions by 37- percent by 2030, and more than doubling the nation’s energy reliance on sustainable sources to 11- percent.
Among the essential sources for Korea is hydrogen fuel cell power.
” I’ve concerned Gyeonggi Green Energy Park, the biggest fuel cell park on the planet. Nevertheless, the entire complex is just about 20- thousand square meters, or the size of about 3 football pitches. As we’re about to discover out, size isn’t really whatever.”.
Integrated in 2013, this park produces 59- megawatts of energy.
That’s sufficient to power 140- thousand houses in neighboring Hwaseong city.
To obtain the comparable power from a solar plant, it would need a plot of land that’s 75 times larger.
Wind farms would depend on 100 times larger.
” Another benefit is that, unlike solar or wind energy, we do not depend on nature, so we can keep producing energy over 90- percent of the time.”.
The concept behind fuel cell innovation is this: you take hydrogen as the primary fuel source and produce a chain reaction with the oxygen in the air.
This response triggers electrical energy and heat.
The only spin-off is H-2-O, or water.
Hydrogen is readily available from different sources, most especially from water, however the procedure of drawing out the hydrogen is expensive and ineffective.
Presently the most convenient method to obtain hydrogen is from gas, so most fuel cells utilize gas to extract hydrogen to make electrical energy.
This * does likewise produce a spin-off of co2, however at a much lower level than other nonrenewable fuel sources.
It likewise produces really low levels of nitrogen oxide and sulfur oxide.
” It’s not made complex to produce hydrogen, however the trouble remains in getting it inexpensively and getting it in mass amounts. Fuel cell innovation, compared with other energy sources, is still at an extremely early phase of advancement. That implies it’s still really costly and challenging for growth.”.
Korea’s moderate environment and restricted land mass implies it’s not well fit for solar or wind energy.
That’s made Korea the 4th greatest nuclear power reliant country, and 82 nd for renewable resource reliance.
The federal government has actually chosen that fuel cell power might supply the service.
” Fuel cell energy produces 9-and-a-half percent of the nation’s renewable resource, however that’s set to increase to 15- percent by2029 Korea presently creates about half the world’s fuel cell energy power, so we’re actually leading the field.”.
Hydrogen fuel cells can likewise be reduced, and their finest understood application in this world is for hydrogen fuel cell cars.
That’s not all.
” Inside here we can discover a fuel cell generator for house usage. It utilizes the very same concept as the fuel cell park we saw previously. Liquid gas and air enters, to produce electrical energy.”.
This generator offers energy for the house of Rah Tae-sang.
It produces enough electrical energy for daily usage, consisting of TELEVISION time and vacuuming, as well as warm water.
Rah is still linked to the nationwide grid, his electrical energy costs have actually fallen substantially.
” Especially in winter season, when we utilize heating units and electrical blankets, we generally utilize a great deal of electrical energy, however that is now covered by the fuel cell generator, therefore we just pay the minimum standard charge for our electrical energy.”.
Like the fuel cell plant, the generator still utilizes natural gas as its hydrogen fuel source, which critics argue does not resolve the basic issue of dependence on fossil fuels.
Professionals state it’s just a matter of time prior to the innovation advances enough to produce hydrogen more inexpensively and effectively, which would reduce the requirement for natural gas and minimize CO2 output.
And the present push for fuel cells in Korea might ultimately supply the service.
” If Korea can establish the innovation that everybody is looking for, not just will it assist resolve the nation’s energy and emissions issues, it will likewise produce brand-new financial and service chances worldwide.”.
