據(jù)OE網(wǎng)站6月9日報道，渦輪機(jī)制造商Siemens Gamesa在周三發(fā)布的一份白皮書中表示，到2030年，風(fēng)電可以在不排放溫室氣體的情況下生產(chǎn)氫氣，其成本可能與目前化石燃料發(fā)電的成本一樣低。

　　決策者們認(rèn)為綠色氫（用可再生能源制造的，不排放碳）是幫助經(jīng)濟(jì)體擺脫對地球變暖能源的依賴和避免氣候變化的重要工具，但同時也希望降低其高昂的成本。

　　Siemens Gamesa表示，到2030年，利用陸上風(fēng)力渦輪機(jī)為電解槽提供動力，從水中提取氫氣的成本可能與使用化石燃料一樣低，而海上風(fēng)力發(fā)電到2035年也可能達(dá)到這一水平。其的成本預(yù)測是基于它所說的二氧化碳排放許可的公平定價。

　　該公司還表示，只有政府和行業(yè)加快建設(shè)可再生能源產(chǎn)能、發(fā)展供應(yīng)鏈和配套基礎(chǔ)設(shè)施，才有可能降低綠色氫的成本并提高產(chǎn)量。我們不能低估以達(dá)到2050年凈零目標(biāo)所需的規(guī)模生產(chǎn)綠色氫所面臨的挑戰(zhàn)。現(xiàn)有的風(fēng)電場可以增加電解槽和電池儲能，靠近需要氫氣的地方也可以開始生產(chǎn)氫氣。

　　主導(dǎo)全球海上風(fēng)力渦輪機(jī)市場的Siemens Gamesa表示，其正在加快開發(fā)一個原型系統(tǒng)，以便在未來五年內(nèi)利用海上風(fēng)力發(fā)電生產(chǎn)氫。

　　該公司希望在不久之后建成第一座工業(yè)規(guī)模的風(fēng)力制氫工廠。

　　長期以來，氫被用作火箭燃料，用于煉油，用于生產(chǎn)化肥的氨，用于制造鋼鐵和化學(xué)品，但這種“灰色”氫的生產(chǎn)通常依賴天然氣或煤炭，在生產(chǎn)過程中會排放大量二氧化碳。

　　雖然各國政府正在尋求將經(jīng)濟(jì)轉(zhuǎn)型為電力驅(qū)動，但他們希望綠色氫也能為更難電氣化的工業(yè)、交通和供暖提供動力。

　　Offshore Wind Could Produce Affordable Hydrogen by 2035 , Siemens Gamesa says

　　Wind power could make it possible to produce hydrogen without emitting greenhouse gases as cheaply as is currently feasible with fossil fuel energy by 2030, turbine maker Siemens Gamesa said in a white paper released on Wednesday.

　　Policymakers see green hydrogen, which is made with renewable power without emitting carbon, as a vital tool to help shift economies away from planet-warming energy sources and to stave off climate change, but want to reduce its sky-high costs.

　　Using onshore wind turbines to power electrolyzers that extract hydrogen from water could become as cheap as making it using fossil fuels by 2030, and offshore wind could get there by 2035, Siemens Gamesa said.

　　Siemens Gamesa said it based its cost forecasts on what it described as fair pricing for permits to emit carbon dioxide.

　　It also said it would only be possible to bring down the cost of green hydrogen and boost production if government and industry speed up building renewable capacity, developing a supply chain and supporting infrastructure.

　　"We can't underestimate the challenge of producing green hydrogen at the scale needed to deliver on the 2050 net-zero targets," it said.

　　Electrolyzers and battery storage can be added to existing wind farms, and sites near places that demand hydrogen can also start to produce it, the company said.

　　Siemens Gamesa, which dominates the global market for offshore wind turbines, said it is speeding up work on a prototype system to produce hydrogen-powered by offshore wind in the next five years.

　　It hopes to follow this with the first industrial-scale wind-to-hydrogen plant shortly afterwards.

　　Hydrogen has long been used as rocket fuel, in oil refining, to produce ammonia for fertilizers and to make steel and chemicals but production of this "grey" hydrogen usually relies on natural gas or coal, in processes that emit large amounts of carbon dioxide.

　　While governments are looking to transform their economies to run on electricity, they hope green hydrogen could also power industry, transport and heating, which are harder to electrify.
