etc.) is amended by adding at the end the following new section:

``SEC. 30D. HYDROGEN INFRASTRUCTURE AND FUEL COSTS.

    ``(a) Allowance of Credit.--There shall be allowed as a credit 
against the tax imposed by this chapter for the taxable year an amount 
equal to the sum of--
            ``(1) the hydrogen infrastructure costs credit determined 
        under subsection (b), and
            ``(2) the hydrogen fuel costs credit determined under

        30 percent of so much of the infrastructure costs for the 
        taxable year as does not exceed $200,000 with respect to such 
        facility.
            ``(2) Eligible hydrogen production and distribution 
        facility.--For purposes of this subsection, the term `eligible 
        hydrogen production and distribution facility' means a hydrogen 
        production and distribution facility which is placed in service 
        after December 31, 2007.
    ``(c) Hydrogen Fuel Costs Credit.--
            ``(1) In general.--For purposes of subsection (a), the

                taxpayer with a production capacity of not more than 25 
                kilowatts of electricity, the lesser of--
                            ``(i) 30 percent of the amount paid or 
                        incurred by the taxpayer during the taxable 
                        year for hydrogen which is consumed by such 
                        device, and
                            ``(ii) $2,000.
