The experiment began this month in Spain, where Repsol prides itself on being the country\u2019s only supplier of 100% renewable gas at public service stations. Compared to e-fuels, which are synthetic fuels manufactured using captured carbon monoxide or carbon dioxide, as well as hydrogen obtained from water splitting, renewable fuels are produced from organic waste.<\/p>\n

Repsol claims that one of the main strengths of renewable fuels is that the carbon dioxide that\u2019s released after they\u2019re burned is equal to the carbon dioxide that was absorbed by the organic matter during their useful life. What\u2019s more, renewable fuels, as well as e-fuels, can be used as drop-in replacements for conventional fuels, which are manufactured from minerals.<\/p>\n
That might not mean much for American car owners, but over in the European Union, more environmentally friendly fuels will play a big role in the future of the combustion vehicle. That\u2019s because the famed 2035 gas ban was slightly watered down late last year<\/a>, allowing automakers to continue selling cars with emissions past the 2035 deadline, as long as they use EU-made low-carbon steel in the vehicles\u2019 construction or sustainable fuels.<\/p>\n The new rules, which have not gone into effect yet, stipulate that automakers need to reduce the tailpipe emissions of their new vehicles by 90% compared to 2021 levels, so pure electric cars will still play a major role in the EU\u2019s strategy.<\/p>\n EV market share has soared in recent months in the region, with battery-electric passenger car registrations reaching 23.3% in May in the EU, EFTA, and UK, surpassing traditional gasoline models, according to the European Automobile Manufacturers\u2019 Association, the main automotive lobby group in Europe. Last May, the EV market share was 17.4%.<\/p>\n However, some industry voices have said that it\u2019s unrealistic to expect a full-on EV takeover in the EU until 2035, which is where hybrids, PHEVs, and sustainable fuels come into play. That said, European carmakers are ramping up their electrification efforts, introducing more and more EVs at different price points, opening up the market to a much wider audience.<\/p>\n \n \t\tWe want your opinion!\n\t<\/p>\n What would you like to see on Insideevs.com?<\/p>\n
