據OE網站6月9日報道,渦輪機制造商Siemens Gamesa在周三發布的一份白皮書中表示,到2030年,風電可以在不排放溫室氣體的情況下生產氫氣,其成本可能與目前化石燃料發電的成本一樣低。
決策者們認為綠色氫(用可再生能源制造的,不排放碳)是幫助經濟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,利用陸上風力渦輪機為電解槽提供動力,從水中提取氫氣的成本可能與使用化石燃料一樣低,而海上風力發電到2035年也可能達到這一水平。其的成本預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,只有政府和行業加快建設可再生能源產能、發展供應鏈和配套基礎設施,才有可能降低綠色氫的成本并提高產量。我們不能低估以達到2050年凈零目標所需的規模生產綠色氫所面臨的挑戰?,F有的風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氫氣。
主導全球海上風力渦輪機市場的Siemens Gamesa表示,其正在加快開發一個原型系統,以便在未來五年內利用海上風力發電生產氫。
該公司希望在不久之后建成第一座工業規模的風力制氫工廠。
長期以來,氫被用作火箭燃料,用于煉油,用于生產化肥的氨,用于制造鋼鐵和化學品,但這種“灰色”氫的生產通常依賴天然氣或煤炭,在生產過程中會排放大量二氧化碳。
雖然各國政府正在尋求將經濟轉型為電力驅動,但他們希望綠色氫也能為更難電氣化的工業、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.
