据路透社11月15日报道，作为减少碳排放努力的一部分，法国天然气网络可能从2030年起进行调整，将天然气与20%氢气混合输送。

氢在燃烧时产生水，而不是产生温室气体二氧化碳，如果它是由风能或太阳能等可再生能源而不是石油和天然气(目前产生的大多数氢的来源)生产，那么它就提供了一种清洁的燃料。

GRTgaz、GRDF、Elengy和其他运营商表示，法国的天然气网络最初可以输送含6%氢气的天然气混合物。他们建议政府到2030年将氢气含量设定为10%，并在此基础上再增加20%。

运营商在巴黎的一次会议上表示，该网络可以在有限的成本下进行调整以应对变化。

德国和其他欧洲国家也一直在研究如何在网络中混合输送天然气和氢气，以减少温室气体的排放。然而，采用氢气作为燃料仍然面临着巨大的挑战。这种气体可以通过电解从水中产生，但它需要大量的电力，因此，如果电力来自化石燃料，其效益就会被削弱。

国际能源署(IEA)在6月份的一份报告中表示，从低碳能源中生产氢仍然很昂贵，而且低碳能源基础设施建设进展缓慢。

国际能源署可再生能源负责人保罗·弗兰克在会议上表示，全球每年生产约7000万吨氢气，相当于5亿辆汽车的消耗量。但他指出，其中90%来自化石燃料，产生约8亿吨二氧化碳。

根据法国能源部的数据，目前法国的氢气主要是由石油和天然气生产的，主要用于工业用途，其二氧化碳排放约占总排放量的3%左右。

在其长期能源计划中，法国的目标是到2023年将工业氢的生产脱碳达10%，并在今年拨出1亿欧元(1.1亿美元)来鼓励氢的使用，特别是在运输领域。

France plans hydrogen blending with natgas to tackle carbon emissions

The French gas network could be adapted to pipe a mix of natural gas with 20% hydrogen from 2030 onwards, as part of efforts to cut carbon emissions, operators said on Friday.

Hydrogen produces water when it burns rather than the greenhouse gas CO2, offering a clean fuel if it is produced from renewable sources such as wind or solar energy, rather than from oil and gas, the source for most hydrogen produced now.

GRTgaz, GRDF, Elengy and other operators said the French network could initially use a mix of natural gas with 6% hydrogen. They recommended that the government set a target of 10% by 2030 and 20% beyond that.

The operators told a conference in Paris that the network could be adapted to deal with the change at a limited cost.

Germany and other European countries have also been studying using a mix of natural gas and hydrogen in their networks to help reduce emissions that are warming the planet.

However, adopting hydrogen as fuel still faced significant challenges. The gas can be produced from water by electrolysis, but it demands large amounts of electricity, so the benefit is undermined if the power is produced from fossil fuels.

The International Energy Agency (IEA) said in a report in June that producing hydrogen from low-carbon energy was still expensive and the development of infrastructure to assist its adoption was proceeding slowly.

IEA renewable energies head Paolo Frankl told the conference about 70 million tonnes of hydrogen was produced globally a year, equivalent to the consumption of about half a billion cars. But he said 90% came from fossil fuels, generating about 800 million tonnes of CO2.

In France, hydrogen is now mostly produced from oil and gas and mainly for industrial use, accounting for about 3% of French emissions, according to the energy ministry.

In its long-term energy plan, France aims to decarbonize industrial hydrogen production by about 10% by 2023 and has set aside 100 million euros ($110 million) this year to encourage hydrogen use, particularly for the transport.
