Thanks, Jim. So when we embarked on our journey several years ago, the IRA did not exist. So while our go-forward mix of opportunities may have changed, the forward outlook and aggregate remains the same for 2025. Because of the IRA and the 45Z Clean Fuel Production Credit and the opportunities these present to produce low carbon intensity fuels, it is driving a reprioritization of our overall capital allocation strategy because of the guaranteed returns backed by the full faith and credit of the U.S. government.
We remain confident that our Advantage Nebraska approach in carbon capture could begin to yield significant returns as early as next year. Our 3 Nebraska facilities, which represent 287 million gallons of capacity at present will be on a pipeline project that already has its trunk line in the ground as a converted natural gas pipeline. So building the laterals to our plants is relatively straightforward. Currently, our pipeline partners continue to make solid progress, and we are on track for starting up in the second half of 2025, and we plan to begin ordering capture equipment in the next several months and expect construction to start later this year. Given that we have first mover status, we are actively exploring redeploying capital to expand the production capacities for our Central City and Wood River, Nebraska facilities by 30 million to 40 million gallons each to take advantage of the early days of the 45Z Clean Fuel Production Credit and position ourselves as a preferred early feedstock supplier to alcohol-to-jet sustainable aviation fuel producers.
We have already seen interest in the supply from multiple different parties, especially with GREET SAF update announced. These are a couple of our premier facilities; already have MSC deployed and have abundant local corn supply. With York, we plan to decarbonize distillation with a small CapEx project to reduce energy usage, which reduces carbon intensity as today qualifies for 45Q, and we want to change that and opportunistically take advantage of early 45Z economics.
And it really doesn't stop in Nebraska. We have 4 other plants on the Summit Carbon pipeline, and they continue to make good progress as well on permitting in the states that we will operate in. With all of that said that current econs, once up and running, we expect Nebraska alone to contribute over $100 million per year in carbon EBITDA starting in the second half of 2025 with the current progress we have made, again, all backed by the 45Z tax credit.
Our MSC and protein since our Fairmont and Madison locations have faced permitting delays for the proposed MSC protein projects for some time now, and we literally received our Illinois permit yesterday. We previously made the decision because of the carbon economics to put the capital allocation for that on hold for the time being and only for the time being, while we turn our attention to our significant return profile of the Advantage Nebraska strategy along with potential clean sugar facility, which was 2x to 3x larger than what we have in Shenandoah, Iowa today.
The returns associated with both carbon capture and clean sugar are driving this and are significantly better than anything else we can do. We will continue to evaluate our overall asset mix, and we are focused on the future of decarbonization and clean sugar as our top 2 priorities after 60% protein or sequence going forward when we evaluate our portfolio.
Part of the permit in Illinois is also the ability to run the plant at an expanded rate to reduce OpEx per gallon and improve margins at that site as we always have had spare capacity, we could not run under the previous permit. We also have several projects to be able to capture carbon and Mount Vernon and Madison under review as well. Those will just be a little further out. While we have not issued a press release, I'm happy to update you on our CST project, clean sugar project in Shenandoah, it is now mechanically complete, and we have begun commissioning over the last month, and we expect to produce on-spec product in the next week or so.
In addition, we are negotiating multiyear contracts for our low carbon-intensity dextrose corn syrups, and we are continuing with substantive late-stage discussions for all of our 2025 volumes to take all of our capacity. We expect to start to sign some agreements even in the next week or so. The clean sugar technology is a game changer of Green Plains and sets us apart as we actively explore plans for site #2.
Lastly, based on current markets and pricing, the uplift in converted margins have remained the same at a minimum of $0.60 a gallon uplift with some products and volumes significantly higher in the $0.80 per gallon or $0.90 per gallon range. This is another reason we want to allocate capital to this versus protein at this point, especially now that we have Shenandoah beginning to operate.
The SAF tax credit and updated GREET model from earlier this week sets the stage for an increased asset valuations for any plant that can decarbonize. The SAF guidance has given us a starting point for rulemaking for the all-important 45Z Clean Fuel Production Credit, which begins this coming January, just 8 months from now, and we remain optimistic this will carry through to that rule making.
A couple of takeaways here, and I think they're really important for everybody to understand. The guidance for SAF was in line with our expectations. And to their credit, they actually lowered some of the unreasonable land-use change penalties associated with corn as a feedstock for alcohol to jet.
Climate-Smart Ag practices are also allowed to count towards CI reduction in corn. It's important to remember that 40B for SAF is just a stepping stone to the 45Z Clean Fuel Production Credit. One really important and lastly, really important point, the common misconception this week on the recent SAF guidance is that low CI corn will be required to qualify, and this is just not the case with CCS or carbon capture, you can get your score low enough to qualify for SAF. And after that, the lower CI corn is just additive to those economics, and we have a significant program around that as well.
Bottom line, there is now a path for U.S. corn-based ethanol to qualify as a feedstock for producing alcohol-to-jet SAF. And the plants that can decarbonize are going to be at a distinct advantage, and this gives us an increased confidence in our Advantage Nebraska strategy and believe that ATJ, sustainable aviation fuel has the potential to fundamentally revalue our asset base or any other plant that's on a pipeline today.
By the way, we were just checking, but to build a new ethanol plant in the United States in our view, could be as high as $2.50 a gallon because we have priced them to see the econs related to when alcohol to jet becomes a reality, and that's a minimum price at this point.
We continue to see Chinese "UCO" weighing on the domestic veg oil prices, including our renewable corn oil, hopefully, new and expanded RD capacity coming online to help to rectify this and balance, and we remain bullish on the long-term value of our low carbon intensity corn oil. However, there is recent pricing pressure from our prior projections when we were using $0.70 a pound that is now currently in the high 30s to low 40s, resulting in EBITDA from our base corn oil uplift to the base ethanol margin of $80 million to $90 million for 2024.
Our MSC uplift has always included an uplift from corn oil yield increases as well, which is where some base pressure came from. Combined with the pricing pressure from lower soybean meal spreads during Q1, although starting to recover with a $40 ton rally from the lows, we are experiencing an MSC uplift of $0.07 to $0.12 a gallon. We believe Sequence margin will more than make up this difference and more which is why we are focused on customer conversions every day in every market around the world.
When we look forward ahead to the opportunity in front of us in 2025, if we assume some normalization, while our mix has changed, our guidance has not. We are still on track for a near $300 million EBITDA contribution from our protein corn oil, clean sugar and decarbonization pillars, excluding any contribution from base ethanol, corporate overhead or Ag and Energy segments, which by the way, has performed well last year and off to a good start this year. I tried every which way I can, but we keep coming up with this result, which is consistent with what we outlined at the beginning of our transformation in 2025.
In protein, our 640 million gallons of converted capacity, including half of our ownership in our joint venture, it could generate a baseload of $80 million to $120 million. As protein spreads widen back out, we will increase, and we will see an increase as we -- as 30% to 50% of our platform moves to Sequence that we believe in 2025.
We also look to add another 1 or 2 production facility in the future, as we mentioned earlier, but we want to make sure we allocate capital to the best projects today. Corn oil contributions on the base business are fully relying on prices, but 2025 should see some recovery as we are approaching the end of the biodiesel tax credit on December 31, and corn oil is an advantaged feedstock relative to those valuations.
The contribution should be a base of $100 million and grow from there. In sugar, our belief that Shenandoah will be fully lined out as we go through this year, and the facility could generate a baseload of $15 million to $25 million a year on a full year basis, depending on what the customer mix ends up.
Again, we have strong customer demand. And as mentioned, we expect food grade certification in around 90 days after we make the on-spec product, hopefully, in the next week or so.
Finally, in decarbonization and Nebraska-First strategy is on track. And based on the latest GREET model, could generate up to and possibly exceeding $110 million a year on an annualized basis from our Nebraska assets alone beginning in 2025 and then grow from there, if we are able to quickly expand those assets and additionally, when Summit Carbon pipeline comes online as well, we will also continually review our asset mix and where we have opportunities to monetize an asset, pay off debt and delever our balance sheet while focusing on our Nebraska first-mover advantage, where a combined expansion of 50 million to 70 million gallons could have an outsized return due to carbon capture, we will do that. Much of our asset base is unencumbered, and we have no near-term maturities and remain in a strong cash position.
We are also focusing, though, on reducing our cost of debt as well as we've seen some opportunities to do that as well. So while you see that the mix has changed from where we originally laid out the transformation, our efforts to transform this earnings power have not wavered notwithstanding a weak Q1 we just reported. Thanks for joining our call today. We can now start the Q&A session.
