SECTION 1. TAX CREDIT FOR HYDROGEN FUEL.

    (a) In General.--Subpart B of part IV of subchapter A of chapter 1 
of the Internal Revenue Code of 1986 is amended by adding at the end 
the following new section:

``SEC. 30D. HYDROGEN CREDIT.

    ``(a) Credit Allowed.--There shall be allowed as a credit against 
the tax imposed by this chapter for the taxable year the sum of the 
qualified hydrogen expenditure amounts for each qualified hydrogen 
device of the taxpayer.
    ``(b) Qualified Hydrogen Expenditure Amount.--For purposes of this 
section, the term `qualified hydrogen expenditure amount' means, with 
respect to each qualified hydrogen energy conversion device of the 
taxpayer, the lesser of--
            ``(1) 30 percent of the amount paid or incurred by the 
        taxpayer during the taxable year for hydrogen which is consumed 
        by such device, and
            ``(2) $1,500.
In the case of any device which is not owned by the taxpayer at all 
times during the taxable year, the $1,500 amount in paragraph (2) shall 
be reduced by an amount which bears the same ratio to $1,500 as the 
portion of the year which such device is not owned by the taxpayer 
bears to the entire year.
    ``(c) Qualified Hydrogen Energy Conversion Devices.--For purposes 
of this section--
            ``(1) In general.--The term `qualified hydrogen energy 
        conversion device' means, with respect to any taxpayer, any 
        hydrogen energy conversion device which is placed in service 
        after December 31, 2004, and which is wholly owned by the 
        taxpayer during the taxable year. If an owner of a device 
        (determined without regard to this paragraph) provides to the 
        primary user of such device a written statement that such user 
        shall be treated as the owner of such device for purposes of 
        this section, then such user (and not such owner) shall be so 
        treated.
            ``(2) Hydrogen energy conversion device.--The term 
        `hydrogen energy conversion device' means--
                    ``(A) any electrochemical device which converts 
                hydrogen into electricity, and

        credit.--So much of the credit which would be allowed under 
        subsection (a) for any taxable year (determined without regard 
        to this subsection) that is attributable to amounts which (but 
        for subsection (e) would be allowed as a deduction under 
        section 162 shall be treated as a credit listed in section 
        38(b) for such taxable year (and not allowed under subsection
