This prospectus supplement supplements the prospectus, dated May 13, 2022 (the "Prospectus"), which forms a part of our registration statement on Form S-1 (No. 333-264115). This prospectus supplement is being filed to update and supplement the information in the Prospectus with the information contained in our Current Report on Form 8-K filed with the Securities and Exchange Commission (the "SEC") on August 18, 2022 (the "Current Report"). Accordingly, we have attached the Current Report to this prospectus supplement.

The Prospectus and this prospectus supplement relate to the resale or other disposition from time to time of (i) up to 3,397,923 shares of our common stock, $0.0001 par value per share, issuable upon the exercise of a warrant to purchase our common stock (the "GEM Warrant") and (ii) up to 125,000,000 shares of our common stock by GEM Yield Bahamas Ltd. ("GYBL") and GEM Global Yield LLC SCS ("GEM Investor"), or other selling securityholders.

The shares of common stock being offered by the selling securityholders have been or may be issued pursuant to the Share Purchase Agreement, dated December 12, 2021, that CITIC Capital Acquisition Corp. entered into with GYBL and GEM Investor (as amended, the "GEM Agreement"). We are not selling any securities under this prospectus and will not receive any of the proceeds from the sale of shares by the selling securityholders. However, we will receive proceeds from any shares issued pursuant to the exercise of the GEM Warrant through the payment of the exercise price in cash and the sale of common stock from any draw downs under the GEM Agreement.

The common stock and Warrants are listed on the New York Stock Exchange ("NYSE") under the symbols "QNGY" and "QNGY WS," respectively. On August 17, 2022, the last reported sales price of our common stock on NYSE was $0.34 per share and the last reported sales price of our Warrants was $0.06 per warrant.

We are an "emerging growth company" as defined under U.S. federal securities laws and, as such, have elected to comply with reduced public company reporting requirements. The Prospectus complies with the requirements that apply to an issuer that is an emerging growth company.

Investing in our securities involves a high degree of risk. You should review carefully the risks and uncertainties described in the section titled "Risk Factors" beginning on page 8 of the Prospectus and under similar headings in any amendments or supplements to the Prospectus.
