Lancaster is a city located in northern Los Angeles and is also the location of California’s “more environmentally friendly” waste hydrogen production plant, which is three times the size of other environmentally friendly hydrogen production facilities. SGH2 said its hydrogen production process is not only the cleanest in the market, but also has more advantages in price and cost.
Whether it is good or bad, many economies in the world are preparing to use hydrogen energy as an important part of the future new energy economy. Japan and South Korea, in particular, have already invested huge funds in this area to vigorously promote this form of zero-emission energy storage.
There are many ways of hydrogen production, from relatively environmentally friendly (using solar energy or wind energy to electrolysis of fresh water) to extremely dirty (lignite gasification), but the cost is also high to the end, the dirtiest is also the cheapest.
This is why the SGH2 project is so interesting-the company claims that it can turn the garbage that would have been discarded in the garbage dump into super environmentally friendly hydrogen at a cheap price.
According to a recent memorandum of understanding, Lancaster will host and jointly own the SGH2 Lancaster plant, which can produce 11,000 kilograms of hydrogen per day, that is, 3.8 million kilograms per year, at the same time, it can handle 42,000 tons of recycled garbage every year. Changing garbage into clean fuel can save 2.1 million to 3.2 million US dollars in landfill costs every year.
Dr. Robert Do, chief executive officer of SGH2, said: “We are the only company in the world that provides green hydrogen, and its cost is competitive compared with the cheapest and dirtiest coal and natural gas hydrogen production, and it costs much less than other green hydrogen. Our technology can be rapidly scaled up to produce fuel 24 hours a day, all year round.”
the process was developed by Solena, the parent company of SGH2, using a high-temperature plasma spray gun with a temperature of 3,500 to 4,000 C(6,332 to 7,232 F). This ionic heat, coupled with the injection of oxygen-enriched gas, catalyzes the “complete dissociation of all hydrocarbon molecules” in any fuel. When it rises and starts to cool down, it will form “a high-quality, hydrogen-rich biosynthetic gas free of tar, soot and heavy metals”.
The process can accept all kinds of waste sources, including paper, used tires, textiles, especially plastics. It can treat these wastes very effectively without producing toxic by-products. The biosynthetic gas is discharged from the top of the pulp chamber, and then sent to the cooling chamber, and then the particulate matter is removed by a pair of pickling machines.
The centrifugal compressor further cleans the gas stream, leaving behind a mixture of hydrogen, carbon monoxide and carbon dioxide. These gases pass through a water-gas conversion reactor and water vapor is added to convert carbon monoxide into carbon dioxide and more hydrogen. The two are separated, and when hydrogen comes out of the other end, all carbon dioxide is neatly captured.
SGH2 said that a life cycle carbon analysis by Berkeley laboratory concluded that, the hydrogen produced by this process can reduce the emission of 23 to 31 tons of carbon dioxide equivalent per ton-this is probably the emission if the waste is burned instead of converted into hydrogen. This will reduce carbon dioxide emissions by 13-19 tons more than any other green hydrogen production process.
More importantly, electrolysis requires 3,000 watt-hours of energy to produce one kilogram of hydrogen, while Solena process is positive, producing 1 per kilogram of hydrogen. 9,000 watt-hours of energy, which means that the factory generates electricity by itself and does not require external power input.
The 5-acre factory, located in the heavy industrial zone of Lancaster, will employ 35 full-time employees and create about 600 construction jobs. SGH2 hopes to break ground in first quarter of 2021 and achieve full operation in 2023. The company is in talks with “California’s largest hydrogenation station owner and operator” to purchase the full output of the plant for 10 years.
