The US Senate Finance Committee is proposing to abolish the hydrogen production tax incentive at the end of the year, delivering a fresh blow to industry efforts to preserve the credit until 2029.
The Senate bill text released late Monday terminates 45V on 1 January 2026, moving its expiration up from 2033 as originally written during former president Joe Biden's administration. The tax-writing committee opted to retain the language pertaining to 45V passed by the Republican-controlled House of Representatives last month. Elsewhere in the text, the Senate proposed an extended phase out of other clean energy tax credits, including solar, wind, nuclear and geothermal.
Clean energy advocates and fossil fuel proponents both lobbied the Senate to extend 45V's expiration date to 2029, which would have brought the credit in line with other renewable energy incentives that will expire closer to the end of the decade. If the Senate passes the bill as it is written, the vast majority of planned clean hydrogen projects are expected to be abandoned.
Only facilities that begin construction before 31 December will be able to access the incentive. However, many companies with clean hydrogen projects in the pipeline held off from making final investment decisions while the previous administration debated the final requirements for 45V. Hydrogen proponents say the timeline between now and the end of the year is likely too narrow for most projects to take off.
Only a few companies have said they expect to be able to begin construction by the end of this year.
