But Corpus Christi\u2019s future fortunes, at least in the eyes of one startup, will be made off a fuel derived from carbon dioxide. If it can be scaled, that fuel could play a vital role in cleaning up the hardest-to-decarbonize portions of the transportation industry from aviation to heavy-duty trucking.<\/p>\n\n\n\n
Since its Corpus Christi facility came online in October, Sacramento, California-based Infinium has become one of the first e-fuel makers in the world to turn industrial-scale production from a concept into a reality.<\/p>\n\n\n\n
At its plant, electrolyzers break down water into hydrogen and oxygen, using electricity generated from nearby wind and solar farms. The hydrogen is then transported to a reactor, where it meets CO2 captured from local refineries, setting off a series of complex chemical reactions aided by patented catalysts. The result is a synthetic fuel with the same chemical properties as its fossil fuel-based cousins.<\/p>\n\n\n\n
On any given day, Infinium produces nearly 8,300 liters of what\u2019s known in the industry as electrofuel or e-fuel and distributes it to customers across the US. A slogan on the company\u2019s trucks reads: \u201cClean fuels made from renewable energy and carbon dioxide.\u201d<\/p>\n\n\n\n
Hydrocarbons \u2014 compounds of hydrogen and carbon atoms \u2014 are the basis of crude oil that is turned into fuels to power everything from trucks to jets. But those atoms can be combined in an industrial setting and made into a substitute fuel that can have lower planet-warming impacts.<\/p>\n\n\n\n
Aviation is responsible for more than 2% of the world\u2019s greenhouse gas emissions. Freight transportation \u2014 done largely by truck, ship and rail \u2014 contributes another 8%. Both figures are expected to balloon in the coming decades as demand for travel and shipping increases while easily decarbonized sectors of the economy cut their emissions. Regulations such as the EU\u2019s increased scrutiny<\/a> of heavy-duty vehicles and its sustainable aviation fuel mandate<\/a> are putting pressure on these industries to clean up their pollution.<\/p>\n\n\n\n With demand soaring, there\u2019s a growing push to fast-track solutions, including but not limited to e-fuels. Practically nonexistent five years ago, the e-fuel market will reach nearly $50 billion by 2030, according to some industry estimates<\/a>. <\/p>\n\n\n\n Using electrolysis to make hydrogen-based products \u2014 the backbone technology for e-fuel \u2014 is not new. Factories deployed the technique to produce ammonia<\/a> as early as the 1920s. Most of those plants were decommissioned in the following years as a cheaper alternative (converting natural gas and coal into ammonia) lured away customers. That alternative, though, is a major source of greenhouse gas emissions, while electrolysis done using clean energy is carbon-free. The tide may be turning again as a growing number of companies, ranging from airlines to freight truck operators, rethink their climate toll.<\/p>\n\n\n While commercial production of e-fuel is still in its infancy, \u201cit\u2019s getting a lot of interest,\u201d says Rose Oates, an analyst with research firm BloombergNEF.<\/p>\n\n\n\n E-fuel can be a \u201cdominant player\u201d in decarbonizing transportation, says Robert Schuetzle, founder and chief executive officer of Infinium. The three-year-old startup has 13 more projects under development in Texas and elsewhere. <\/p>\n\n\n\n At Infinium\u2019s Corpus Christi facility, machinery works day and night to produce mostly e-diesel for trucking, alongside e-kerosene as a jet fuel and e-naphtha, which is commonly used as a solvent. If the facility runs at full capacity, it can make roughly 3 million liters of e-fuel each year. The company doesn\u2019t break down the volume of each product, but if all of it was e-diesel, it would be enough to power one truck with a payload of 20-odd tons on 190 trips around the equator.<\/p>\n\n\n\n Amazon, which has pledged<\/a> to zero out its emissions by 2040, has claimed a chunk of the fuel. While the e-commerce giant is increasingly electrifying<\/a> its delivery vehicles, e-fuel is a \u201cpromising tool for reducing emissions\u201d in freight transportation, says Chris Atkins, Amazon\u2019s director of worldwide operations sustainability. That\u2019s because e-diesel could deliver immediate climate gains without a massive infrastructure overhaul, he says.<\/p>\n\n\n\n Hundreds of miles away from Corpus Christi, Infinium is building another facility in West Texas to create sustainable aviation fuel. American Airlines has already agreed to buy fuel once production begins, likely in 2026, according to Infinium.<\/p>\n\n\n\n Governments worldwide have urged<\/a> the transportation sector to reduce carbon emissions and offered generous incentives<\/a> to help do so. With the cost of renewables dropping dramatically \u2014 solar, for instance, has fallen more than 80%<\/a> since 2010 \u2014 e-fuel has become more technologically and economically feasible.<\/p>\n\n\n\n \u201cThe acceleration is happening,\u201d says Schuetzle. Despite spending 15 years making alternative fuel from feedstocks including biomass and waste gas from the fossil fuel industry\u2019s gas flaring systems, it wasn\u2019t until 2020 that market appetite for e-fuel convinced him to launch Infinium.<\/p>\n\n\n\n \u201cIt\u2019s still early in the game, but e-fuel will be a very dominant discussion point and platform for decarbonization of heavy transport and chemicals,\u201d Schuetzle says. \u201cCustomers are really focused on buying e-fuel and paying a premium for the carbon abatement potential.\u201d<\/p>\n\n\n\n E-fuel faces competition from biofuel made from soy and corn, which the transportation sector is increasingly adding to its fuel mix. Globally, biofuel consumption reached an all-time high<\/a> of 170 billion liters in 2022, most of which was used in road transport, data from the International Energy Agency shows. By contrast, commercial-scale e-fuel makers are few and far between. Electric trucks are also hitting the road<\/a>, adding another carbon-free option for freight operators. <\/p>\n\n\n\n Neither of those is a perfect solution. Biofuel made from corn can worsen water scarcity<\/a> and compete<\/a> with food production. And much more charging infrastructure is needed to move large quantities of goods around with battery-powered trucks.<\/p>\n\n\n To achieve net-zero emissions globally, the IEA estimates<\/a> that carbon emissions from heavy-duty vehicles has to drop 15% by 2030 compared to their current levels. E-fuel is one of the easy decarbonization solutions trucking companies could use to accelerate that effort. E-fuel could also help decarbonize aviation. In fact, the United Nations\u2019 International Civil Aviation Organization predicts that e-fuel will constitute<\/a> as much as 55% of global jet fuel by mid-century, if technological advancements take place and governments enact supportive policies. Shipping \u2014 another industry with no easy climate solutions \u2014 could also benefit from e-fuel.<\/p>\n\n\n\n How Infinium fits into that future remains to be seen. Schuetzle is tight-lipped about the company\u2019s exact plans. While acknowledging that Infinium\u2019s e-fuel is \u201cmore expensive\u201d than conventional fuel, he didn\u2019t disclose the cost difference. Schuetzle also declined to share the amount of CO2 that would otherwise have been vented into the atmosphere if the Corpus Christi facility didn\u2019t use it as feedstock, citing proprietary concerns, nor would he reveal the water footprint of Infinium\u2019s plant.<\/p>\n\n\n\n Water is essential to producing hydrogen through electrolysis and it is a potential flashpoint<\/a> with local communities. Infinium says that its water use is \u201cvery efficient.\u201d When taking into account all the emissions from fuel production, processing, distribution and consumption, the startup says its product emits 95% less CO2 than conventional fuel.<\/p>\n\n\n\n It is \u201cvery close to a net-zero carbon fuel,\u201d Schuetzle says.<\/p>\n\n\n\n But not everyone agrees on e-fuel delivering on its promises, particularly when the technology uses CO2 captured at smokestacks.<\/p>\n\n\n\n \u201cIt depends on how you count,\u201d says Pierpaolo Cazzola, a research fellow at Columbia University\u2019s Center on Global Energy Policy. Compared to releasing CO2 from fossil fuel-burning factories into the atmosphere, it is more climate-friendly to capture the carbon and utilize it in e-fuel production, Cazzola says. But that gas is only stored temporarily, he adds. Once e-fuel is combusted, it releases CO2 just as traditional fuel does.<\/p>\n\n\n\n \u201cThis is not CO2 neutral,\u201d Cazzola says. \u201cThere would still be a net addition of carbon in the atmosphere.\u201d<\/p>\n\n\n\n Some regulators seem to agree with that thinking. The EU will phase out<\/a> government subsidies for e-fuel made with fossil fuel-sourced CO2 by 2041. For now, though, the gas captured at power plants and factories is a key source of feedstock for making e-fuel.<\/p>\n\n\n\n To address this issue, Infinium says it will source so-called biogenic waste carbon from paper mills or ethanol plants. Wood and plant waste contains CO2 naturally pulled from the atmosphere, which can help lower the resulting fuel\u2019s carbon intensity. Infinium also plans to get carbon feedstock from companies removing CO2 from the atmosphere using a process known as direct air capture.<\/p>\n\n\n\n But that technology itself is nascent<\/a>, and CO2 captured this way can cost hundreds of dollars or more per ton, which adds to the cost of making e-fuel. The supply of captured biogenic CO2 emissions has its own issues as resource-intensive paper mills and ethanol factories come with environmental sustainability challenges<\/a>. <\/p>\n\n\n Even if e-fuel makers overcome the supply chain obstacles, high price points make for an uphill battle against traditional fuels. Take kerosene, the fuel that keeps the world\u2019s planes in the sky. Making e-kerosene from biogenic carbon emissions, water and renewable energy is at least four times more expensive<\/a> compared to traditional fuel, according to the IEA. A drop in the cost of electrolyzers and renewable energy will help lower the price of e-kerosene, but it could still be double or triple<\/a> that of its petroleum counterpart in 2030, the IEA says. <\/p>\n\n\n\n And not every e-fuel is created equal. While e-diesel and e-kerosene can be \u201cdrop-in\u201d solutions to decarbonize trucking and aviation that don\u2019t require costly equipment upgrades, e-ammonia and e-methanol as shipping fuel cannot. The added costs to use those fuels will pose yet another hurdle.<\/p>\n\n\n\n Despite e-fuel makers promising a major scale-up this decade, it will make an \u201cunnoticeable dent\u201d in transportation emissions, says Oates at BNEF. \u201cThis is down to a combination of nascent technology and high cost of e-fuel production,\u201d she adds.<\/p>\n\n\n\n The IEA estimates that more than 200 e-fuel projects<\/a> have been announced around the world in recent years. Yet plants that have finalized investment commitments amount to less than 5%<\/a> of the planned capacity. <\/p>\n\n\n\n E-fuel production will also face a \u201cdouble limitation\u201d as it scales up, says Cazzola. Gaining access to abundant renewable energy and carbon-emitting factories is vital to producing e-fuel, yet the two resources aren\u2019t often sited in the same location. Until direct air capture technology matures, that geographic constraint will persist, Cazzola says.<\/p>\n\n\n\n Schuetzle agrees that e-fuel makers \u201ccan\u2019t do these projects anywhere on the globe quite yet.\u201d But Infinium has identified some 20 locations worldwide with both resources for e-fuel production, he notes, and the company is in search of more options.<\/p>\n\n\n\n It\u2019s not alone in trying to grow the industry. Twelve, another California-based startup, is building a plant<\/a> in Washington state and recently fired up a new CO2 converter<\/a>. In Norway, Nordic Electrofuel has announced<\/a> ambitious plans to ramp up domestic production of e-kerosene, and so have companies<\/a> in France and Germany.<\/p>\n\n\n\n But the future growth of e-fuel production is ultimately linked to the advancement of direct air capture. \u201cThat really helps us to go anywhere on the globe,\u201d Schuetzle says.<\/p>\n","protected":false},"excerpt":{"rendered":" The economy of Corpus Christi, Texas, is largely built on fossil fuels.
