the future become, affiliated

   1.                                                   You disclose that
"certain of our officers and directors currently serve in similar roles for
                                                        Tortoise Acquisition I,
a blank check company incorporated as a Delaware corporation
                                                        and formed for the
purpose of effecting its own initial business combination," and at page
                                                        80 you state that your
"management team will include all of the members of the
                                                        management team of
Tortoise Acquisition I." However, at page 28 you disclose that "Our
                                                        sponsor, officers and
directors have agreed, pursuant to a written letter agreement, not
                                                        to participate in the
formation of, or become an officer or director of, any other blank
                                                        check company until we

       business combination." Please file the executed version of the letter
agreement you list as
       exhibit 10.2, and revise your prospectus to disclose the date of the
referenced
       agreement and to clarify or reconcile any potential disclosure
discrepancy.
2.     We note that the registrant was formed as a Cayman Islands company
approximately one
       month after Tortoise Acquisition I announced its proposed business
combination with
       Hyliion. In light of the provision from your letter agreement regarding
the timing and
       potential for similar endeavors by your officers and directors, tell us
whether there are any
       formal or informal agreements among your sponsor and members of your
management
       team to replicate the same business model or form additional blank check
       companies once you find a suitable target for the registrant. If such
agreements exist,
       please disclose the particulars in the revised prospectus.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
statement.

        You may contact Wei Lu, Staff Accountant, at (202) 551-3725 or Ethan
