A maglev blower uses magnetic bearings and high-tech to compress and transport air to the desired place in an energy-saving and environmentally friendly way.

Moreover, there is surging demand for heat pump water heaters, which gather ambient warmth from the air and compress it to heat up water, especially in Germany, Poland, the Netherlands and the United Kingdom, with orders soaring more than 100 percent year-on-year in the past 90 days, said Alibaba.

When power consumption is lower than the amount generated by new energies, the excess power will be used to compress the air into a salt cavern.

In Heilongjiang province, State Power Investment Corp has been working on a technology to compress corn straw, residues and agricultural and associated processing wastes into fuel to provide clean heating to local residents.

State Power Investment Corp's attempt to compress corn straw, understory residues and agricultural and related processing wastes into fuel, however, is expected to represent a breakthrough for biomass heating in the country, said Luo Zuoxian, head of intelligence and research at the Sinopec Economics and Development Research Institute.
