Warrant Certificate 

 

This Warrant Certificate certifies that                      , or registered assigns, is the registered holder of warrant(s) evidenced hereby (the “Warrants”
and each, a “Warrant”) to purchase ordinary shares, no par value per share (“Ordinary Shares”),
of Energy Cloud I Acquisition Corporation, a British Virgin Islands Limited Company (the “Company”). Each whole
Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive from the
Company that number of fully paid and non-assessable shares of Ordinary Shares as set forth below, at the exercise price (the
“Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless
exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate
and payment of the Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions as set forth
herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given
to them in the Warrant Agreement. 

 

Each whole Warrant is initially exercisable for
one fully paid and non-assessable share of Ordinary Shares. No fractional shares will be issued upon exercise of any Warrant.
If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a share of Ordinary Shares, the Company
will, upon exercise, round down to the nearest whole number the number of shares of Ordinary Shares to be issued to the Warrant holder.
The number of shares of Ordinary Shares issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain
events, as set forth in the Warrant Agreement. 

 

The initial Exercise Price per share of Ordinary
Shares for any Warrant is equal to $11.50 per share. The Exercise Price is subject to adjustment upon the occurrence of certain events,
as set forth in the Warrant Agreement. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant Agreement. 

 

Subject to the conditions set forth in the Warrant
Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period,
such Warrants shall become void. 

 

     

     

    

 

Reference is hereby made to the further provisions
of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as
though fully set forth at this place. 

 

This Warrant Certificate shall not be valid unless
countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. 

 

This Warrant Certificate shall be governed by
and construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

[Form of Warrant Certificate] 

[Reverse] 

 

The Warrants evidenced by this Warrant Certificate
are part of a duly authorized issue of Warrants entitling the holder on exercise to receive shares of Ordinary Shares and are issued or
to be issued pursuant to a Warrant Agreement dated as of [   ], 2021 (the “Warrant Agreement”),
duly executed and delivered by the Company to Continental Stock Transfer& Trust Company, a New York corporation, as warrant agent
(the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder
of the Warrant Agent, the Company and the holders (the words “holders” or “holder”
meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by
the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have
the meanings given to them in the Warrant Agreement. 

 

Warrants may be exercised at any time during the
Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by
surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together
with payment of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in
the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced
hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the
holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised. 

 

Notwithstanding anything else in this Warrant
Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering
the issuance of the shares of Ordinary Shares to be issued upon exercise is effective under the Securities Act and (ii) a prospectus
thereunder relating to the shares of Ordinary Shares is current, except through “cashless exercise” as provided for in the
Warrant Agreement. 

 

The Warrant Agreement provides that upon the occurrence
of certain events the number of shares of Ordinary Shares issuable upon exercise of the Warrants set forth on the face hereof may, subject
to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest
in a share of Ordinary Shares, the Company shall, upon exercise, round down to the nearest whole number of shares of Ordinary Shares to
be issued to the holder of the Warrant. 

 

Warrant Certificates, when surrendered at the
principal corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney
duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without
payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like
number of Warrants. 

 

Upon due presentation for registration of transfer
of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing
in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the
limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith. 

 

The Company and the Warrant Agent may deem and
treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership
or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for
all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants
nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder of the Company.
