      that:




1.  I
      have
      reviewed this Annual Report on Form 10-KSB of HydroGen Corporation for the
      year
      ended December 31, 2007;




2.  Based
      on
      my knowledge, this report does not contain any untrue statement of a material
      fact or omit to state a material fact necessary to make the statements made,
      in
      light of the circumstances under which such statements were made, not misleading
      with respect to the period covered by this report;




3.  Based
      on
      my knowledge, the financial statements, and other financial information included
      in this report, fairly present in all material respects the financial condition,
      results of operations and cash flows of the registrant as of, and for, the
      periods presented in this report;




4.  The
      registrant’s other certifying officers and I are responsible for establishing
      and maintaining disclosure controls and procedures (as defined in Exchange
      Act
      Rules 13(a)-15(e) and 15(d)-15(e)) and internal control over financial reporting
      (as defined in Exchange Act Rules 13(a)-15(f) and 15(d)-15(f) for the registrant
      and have:




(a)  Designed
      such disclosure controls and procedures, or caused such disclosure controls
      and
      procedures to be designed under our supervision, to ensure that material
      information relating to the registrant, including its consolidated subsidiaries,
      is made known to us by others within those entities, particularly during the
      period in which this report is being prepared;




(b)  Designed
      such internal control over financial reporting, or caused such internal control
      over financial reporting to be designed under our supervision, to provide
      reasonable assurance regarding the reliability of financial reporting and the
      preparation of financial statements for external purposes in accordance with
      generally accepted accounting principles.




(c)  Evaluated
      the effectiveness of the registrant’s disclosure controls and procedures and
      presented in this report our conclusions about the effectiveness of the
      disclosure controls and procedures as of the end of the period covered by this
      report based on such evaluation; and




(d)  Disclosed
      in this report any change in the registrant’s internal control over financial
      reporting that occurred during the registrant’s most recent fiscal quarter that
      has materially affected, or is reasonably likely to materially affect, the
      registrant’s internal control over financial reporting; and




5.  The
      registrant’s other certifying officers and I have disclosed, based on our most
      recent evaluation, to the registrant’s auditors and the audit committee of
      registrant’s board of directors (or persons performing the equivalent
      functions):




(a)  All
      significant deficiencies and material weaknesses in the design or operation
      of
      internal control over financial reporting which are reasonably likely to
      adversely affect the registrant’s ability to record, process, summarize and
      report financial information; and




(b)  Any
      fraud, whether or not material, that involves management or other employees
      who
      have a significant role in the registrant’s internal control over financial
      reporting.
