中國石化新聞網(wǎng)訊 據(jù)油氣新聞網(wǎng)1月12日報道，根據(jù)歐洲專利局(EPO)和國際能源署(IEA)對專利的聯(lián)合研究，氫技術(shù)的發(fā)展正在轉(zhuǎn)向電解等低排放解決方案。

該報告是第一份此類報告，使用全球?qū)＠麛?shù)據(jù)對所有氫技術(shù)的創(chuàng)新進行全面的最新分析。其涵蓋了從氫供應(yīng)到存儲、分配和轉(zhuǎn)化，以及最終用途應(yīng)用的所有技術(shù)。

國際能源署執(zhí)行主任法提赫·比羅爾表示，低排放源的氫氣可以在清潔能源轉(zhuǎn)型中發(fā)揮重要作用，有可能在諸如長途運輸和化肥生產(chǎn)等清潔替代品很少的行業(yè)替代化石燃料。這項研究表明，創(chuàng)新者正在響應(yīng)競爭性氫供應(yīng)鏈的需求，而且確定了需要付出更多努力的領(lǐng)域，特別是終端用戶。我們將繼續(xù)幫助各國政府推動安全、有彈性和可持續(xù)的清潔能源技術(shù)的創(chuàng)新。

EPO總裁António Campinos表示，利用氫的潛力是歐洲到2050年實現(xiàn)氣候中和戰(zhàn)略的關(guān)鍵部分。但是，如果氫要在減少二氧化碳排放方面發(fā)揮重要作用，就迫切需要在一系列技術(shù)上進行創(chuàng)新。該報告揭示了各國和行業(yè)部門之間一些令人鼓舞的轉(zhuǎn)型模式，包括歐洲對新氫技術(shù)的出現(xiàn)作出的主要貢獻。其還強調(diào)了初創(chuàng)企業(yè)對氫創(chuàng)新的貢獻，以及他們依賴專利將發(fā)明推向市場。

該研究介紹了2011年至2020年氫技術(shù)的主要趨勢，以國際專利家族（IPF）衡量的話，其中每一個都代表了一項高價值的發(fā)明，其專利申請已在全球兩個或多個專利局提交。該報告發(fā)現(xiàn)，全球氫專利由歐盟和日本主導(dǎo)，這兩個國家在過去十年中申請的IPF顯著增長，分別占28%和24%。歐洲主要國家是德國（占全球總數(shù)的11%）、法國（6%）和荷蘭（3%）。

擁有20%的氫相關(guān)專利的美國，是過去十年中唯一一個國際氫專利申請下降的主要創(chuàng)新中心。韓國和亞洲大國在氫技術(shù)方面的國際專利申請活動仍然平穩(wěn)，但仍在上升。除這五個主要創(chuàng)新中心外，其他產(chǎn)生大量氫氣專利的國家包括英國、瑞士和加拿大。

2011—2020年期間，制氫技術(shù)占氫專利數(shù)量最多。雖然目前全球制氫幾乎完全基于化石燃料，但專利數(shù)據(jù)顯示，低排放創(chuàng)新在氫價值鏈各個環(huán)節(jié)產(chǎn)生的國際專利數(shù)量是現(xiàn)有技術(shù)的兩倍多。

2020年，受氣候問題推動的技術(shù)占所有與氫生產(chǎn)相關(guān)的專利的近80%，其增長主要由電解創(chuàng)新的大幅增加推動。最具創(chuàng)新性的地區(qū)現(xiàn)在正在競相舉辦第一個工業(yè)推廣階段，根據(jù)數(shù)據(jù)表明，歐洲正在成為投資新電解槽制造能力的地區(qū)。

在氫的許多潛在最終用途中，汽車行業(yè)長期以來一直是創(chuàng)新的重點，該領(lǐng)域的專利申請持續(xù)增長，主要由日本主導(dǎo)。盡管近年來政策和媒體一致關(guān)注氫在長途運輸、航空、發(fā)電和供暖方面的脫碳潛力，但在其他最終用途應(yīng)用中還沒有看到類似的勢頭。

如果不解決這些部門化石燃料使用不減的問題，就無法實現(xiàn)國家凈零排放承諾。一個亮點是最近使用氫來脫碳鋼鐵生產(chǎn)的專利申請有所增加——這可能是對《巴黎協(xié)定》后共識的回應(yīng)，即該行業(yè)需要快速減排的根本解決方案。

對于成熟的氫技術(shù)，創(chuàng)新主要由歐洲化工產(chǎn)業(yè)主導(dǎo)，該行業(yè)的專業(yè)知識也使其在電解和燃料電池等氣候驅(qū)動技術(shù)方面處于領(lǐng)先地位。

汽車公司也很活躍，不僅僅是汽車技術(shù)。在這些專利背后，2011—2020年，大學(xué)和公共研究機構(gòu)創(chuàng)造了13.5%的與氫相關(guān)的國際專利，由法國和韓國機構(gòu)主導(dǎo)，重點是電解等低排放氫生產(chǎn)方法。

該研究發(fā)現(xiàn)，2011—2020年對氫能公司的100億美元風(fēng)險投資中，有一半以上流向了擁有專利的初創(chuàng)企業(yè)，盡管他們在報告的數(shù)據(jù)集的初創(chuàng)企業(yè)中所占比例不到三分之一。持有專利是一個初創(chuàng)企業(yè)能否繼續(xù)吸引資金的良好指標：2011—2020年，超過80%的氫初創(chuàng)企業(yè)后期投資都流向了已經(jīng)在電解、燃料電池或從天然氣中生產(chǎn)氫的低排放方法等領(lǐng)域提交專利申請的公司。

Hydrogen advances shifting towards clean energy:IEA

Hydrogen technology development is shifting towards low-emissions solutions such as electrolysis, according to a joint study of patents by the European Patent Office (EPO) and the International Energy Agency (IEA).

The report is the first of its kind and uses global patent data to provide comprehensive up-to-date analysis of innovation in all hydrogen technologies. It covers the full range of technologies, from hydrogen supply to storage, distribution and transformation, as well as end-use applications.

“Hydrogen from low-emissions sources can play an important role in clean energy transitions with potential to replace fossil fuels in industries where few clean alternatives exist, like long-haul transport and fertilizer production,” said IEA Executive Director Fatih Birol.

“This study shows that innovators are responding to the need for competitive hydrogen supply chains, but also identifies areas – particularly among end-users – where more effort is required. We will continue to help governments spur innovation for secure, resilient and sustainable clean energy technologies.”

“Harnessing the potential of hydrogen is a key part of Europe’s strategy to achieve climate neutrality by 2050,” said EPO President António Campinos.

“But if hydrogen is to play a major role in reducing CO2 emissions, innovation is urgently needed across a range of technologies. This report reveals some encouraging transition patterns across countries and industry sectors, including Europe’s major contribution to the emergence of new hydrogen technologies. It also highlights the contribution of start-ups to hydrogen innovation, and their reliance on patents to bring their inventions to market.”

The study presents the major trends in hydrogen technologies from 2011 to 2020, measured in terms of international patent families (IPFs), each of which represents a high-value invention for which patent applications have been filed at two or more patent offices worldwide. The report finds that global patenting in hydrogen is led by the European Union and Japan, which account for 28% and 24% respectively of all IPFs filed in this period, with significant growth in the past decade. The leading countries in Europe are Germany (11% of the global total), France (6%), and the Netherlands (3%).

The US, with 20% of all hydrogen-related patents, is the only major innovation centre to see international hydrogen patent applications decline in the past decade. International patenting activity in hydrogen technologies remained modest in South Korea and the biggest country in Asia but is on the rise. In addition to these five main innovation centres, other countries generating significant volumes of hydrogen patents include the United Kingdom, Switzerland and Canada.

Hydrogen production technologies accounted for the largest number of hydrogen patents over the 2011-2020 period. While global hydrogen production is currently almost entirely fossil-based, the patenting data shows that low-emissions innovations generated more than twice the number of international patents across all segments of the hydrogen value chain than established technologies.

Technologies motivated by climate concerns accounted for nearly 80% of all patents related to hydrogen production in 2020, with growth driven chiefly by a sharp increase of innovation in electrolysis. The most innovative regions are now competing to host the first industrial roll-out phase, with the data suggesting that Europe is gaining an edge as a location for investment in new electrolyser manufacturing capacity.

Among hydrogen’s many potential end-use applications, the automotive sector has long been the focus for innovation, and patenting in this sector continues to grow, led mainly by Japan. Similar momentum is not yet visible in other end-use applications, despite concerted policy and media attention in recent years on hydrogen’s potential to decarbonise long-distance transport, aviation, power generation and heating.

National net zero emissions pledges cannot be achieved without addressing unabated fossil fuel use in these sectors. One bright spot is a recent uptick in patenting for the use of hydrogen to decarbonise steel production – possibly in response to the post-Paris Agreement consensus that the sector needs radical solutions to cut emissions quickly.

For established hydrogen technologies, innovation is dominated by the European chemical industry, whose expertise in this sector has also given it a head start in climate-motivated technologies such as electrolysis and fuel cells.

Automotive companies are also active, and not just for vehicle technology. Behind them, universities and public research institutes generated 13.5% of all hydrogen-related international patents in 2011-2020, led by French and Korean institutions, with a focus on low-emissions hydrogen production methods such as electrolysis.

The study finds that more than half of the $10 billion of venture capital investment into hydrogen firms in 2011-2020 went to start-ups with patents, despite them making up less than a third of the start-ups in the report’s data set. Holding a patent is a good indicator of whether a start-up will keep attracting finance: more than 80% of late-stage investment in hydrogen start-ups in 2011-2020 went to companies that had already filed a patent application in areas such as electrolysis, fuel cells, or low-emissions methods for producing hydrogen from gas.
