Plug Power (PLUG) experienced significant growth recently, with its shares surging more than 45% in the past month. This surge was attributed to the unexpected extension of the 45V clean hydrogen production tax credit. The extension was part of the US Senate's revised version of President Donald Trump's substantial tax and spending bill, which he signed into law. The move provided a boost to Plug Power's stock performance. The green hydrogen sector, which Plug Power operates in, is drawing increased attention from investors due to favorable policy changes. The extension of the tax credit is seen as a positive sign of the government's commitment to incentivizing clean energy production. Overall, the market response to the news has been optimistic, with Plug Power's rally reflecting growing confidence in the potential of green hydrogen as a sustainable energy solution.
