A Novel Technology, But Are There Better Uses For The Renewable Power?

We don’t want to throw cold water on a very HOT idea, but the BASF, SABIC, Linde announcement of collaboration on electric furnaces for ethylene production is not the first that we have seen, as both Dow and Shell have stated that they are looking at similar ideas. As an “endgame” objective this is interesting, as it would remove the need for natural gas fuel and greatly reduce emissions, but despite the claims in the release, this is an interesting pilot project at best today. It is a credible process, and the companies have likely achieved ethylene production this way on a lab scale. It is possible to get significantly higher temperatures today through electric power than the 800c (1500f) suggested in the article. Some plasma jet technology can achieve temperatures in the 1000s of degrees centigrade, but the power consumption is extremely high, and it is worth noting that the press release does not mention the possible power requirements to get to a metric ton of ethylene.  Modern ethylene units produce a million tons a year (or more) – which is around 2 metric tons per minute. The better technologies involve raising the feedstocks to very high temperatures very quickly (measured in fractions of a second). The partners talk about achieving electric power-based ethylene at scale. This is a lofty goal. Should they succeed, not only would ethylene plants require significant retrofitting at the front end at very high capital cost, but the power requirements would be enormous, putting even greater strain on global and regional renewable power ambitions, that already looks hard to achieve, given all of the competing needs. We would want to ask two questions:

  • Are you better off making hydrogen and using hydrogen as a furnace fuel in a traditional and well-practiced ethylene process – this would likely mean much lower capital refit costs?  
  • Are you better off still just capturing and sequestering the CO2 from existing facilities?

With many of these “cleaner” objectives and theoretical technologies, there may be other more practical workarounds, and if not they still probably do not make sense until there is such an abundance of renewable power that the incremental cost of power is very low for 95% of the time.

Industrial Gas Companies - Likely to Dominate in Hydrogen

Mar 23, 2021 11:29:43 AM / by Graham Copley posted in ESG, Hydrogen, CCS, CO2

We note the Air Liquide announcements of its ESG objectives this week. Industrial gas companies have some of the greatest challenges and some of the greatest opportunities when it comes to clean energy and emission. As the largest producers of hydrogen (from natural gas) they have very large carbon footprints and these are made worse by the power consumption required to run their many air separation units to make oxygen and nitrogen. At the same time, they are the most logical producers of blue hydrogen – using CCS, but most of their existing hydrogen capacity is tied up under long-term contracts with refineries and chemical producers. Making blue hydrogen through capturing the CO2 would only make sense where the primary customer wanted it, or where there was enough slack in the system to free up blue hydrogen to make blue ammonia or to use directly for power generation or transport. Like Linde and Air Products, Air Liquide operates hydrogen grids where there are several consumers in relative proximity – these would seem the most logical places to find meaningful blue hydrogen opportunities and the US Gulf is a more obvious location.

More Recycling Semantics & Fresh CCS Initiatives

Mar 19, 2021 10:41:57 AM / by Graham Copley posted in ESG, Recycling

We have to again take issue with the phrase “advanced recycling” as we believe that it is neither advanced nor is it really recycling. Most companies are using the phrase to describe the process of taking a product that has had a 60-90 cents per pound value in use and breaking it back down to a liquid hydrocarbon that is worth less than 20 cents a pound. When this is then reused as a chemical feedstock, the maximum conversion to polymers is 50% with the rest going to other chemicals and other fuels. Because of losses in the initial stage of the process you are going to get at best a 40% rate of recycling back into the original polymer uses. This is a convenient solution for the major polymer producers as it allows them to maintain rates on their virgin polymer plants while claiming to participate in the recycling (closed-loop) process – even if the loop is far from closed.

Too Many New ESG Directives Make it Hard to Motivate Staff

Mar 18, 2021 1:55:32 PM / by Graham Copley posted in ESG, Carbon Tax, biodiversity

0 Comments

We note the Blackrock headline below about protecting biodiversity among other things and relate this to a section we wrote in yesterday’s ESG and Climate piece around carbon taxes and staff motivation. Companies are being asked to do too much and address too many issues at once that do not have empirical frameworks:

  • Lower your environmental footprint
  • Reduce waste
  • Increase diversity
  • Become more sustainable
  • Protect the natural environment
  • Oh, and while you are doing it, increase shareholder value!

In response, PR savvy companies are making broad statements around intent, even if they are not sure what to do next or whether it can be measured and valued. In extreme cases, these statements of intent, especially if they are very selective in the data they use or the topics covered, increase the chances that companies get accused of “greenwashing” – note the Chevron news this week and our comments in the report linked above.

But there is a further problem that will be causing major headaches in many companies – how do you motivate staff. Energy, Industrial and Materials companies are under fire, and while some may be putting on a brave and collaborative external face, internally they all have problems, as staff (at all levels) are confused – they see their industry and therefore their jobs at risk and they see new intangible objectives being imposed in the press and in some cases by shareholders that they have no experience and/or no idea how to fix. Plus – there are now too many issues to address and the likelihood that none gets the necessary focus and all fall short is very high. Everything in the list above is important, but there will only be a handful of standouts who over the next 5 years make enough progress on all fronts, and the more progressive management teams in the eyes of the press and the shareholders cannot afford to take their eyes of staff, who they might unconsciously be alienating through their public stance, but without whom they will not be able to get anything done.

As we discussed yesterday, a carbon tax, might be unpopular with politicians, but if I am the CEO of an energy or chemical company, the imposition of something tangible gives me something to rally the troops around. Intangible is much harder and setting tangible internal goals without a tangible external frame of reference other than “do better”, is much harder.

Just taking one example, the map below shows the level of CCS pipeline infrastructure that the US might need for an optimal carbon sequestration model. Almost none of this exist today, but a carbon tax could rally employees around new objectives associated with this.

The Mix of Plastics May Get Worse

Mar 17, 2021 12:38:41 PM / by Graham Copley posted in Plastics, biodegradable

0 Comments

We are focusing on one of the recycling headlines in today's ESG & Climate Report referencing a collaboration between Mars Wrigley and Danimer Scientific. The news release highlights two important issues – using biodegradable polymers where they are most fit for purpose, in this case, single-use candy wrappers – and the need for consumer education. We already have a confusing set of labels for polymers, as summarized in the image below, and adding biodegradable plastics, which would contaminate a recycle stream even further, requires a huge leap of faith that consumers can not only identify the products that can be composted but are willing to do so.

Green Hydrogen - Still Far Too Expensive

Mar 16, 2021 1:15:39 PM / by Graham Copley posted in ESG, Hydrogen, Coal

0 Comments

The cost of the green hydrogen project in Australia listed below is extremely high. Ethylene (a complex petrochemical) is now down to a cost of around $1.00 per pound if built efficiently – which is $2,200 per metric ton of capacity. The hydrogen project linked - if the $0.5bn and the 33,000 metric ton hydrogen capacity are correct, works out at around $15,000 per metric ton of capital costs. To get a 15% return on the project they will need $2,300 per ton of margin, above all operating costs. In the chart below, this would represent a capital charge of more than one dollar per pound, much more than is implied in the green bar. This does not look economic to us and will require either significant government subsidies – or severe penalties on hydrocarbons to make the hydrogen economic on a relative basis. The project does involve selling some power to the grid, but we still struggle to see how this hydrogen can be an economic fuel alternative.

“Adapt or Die” vs “Adapt to Thrive” - The Messaging Makes All The Difference

Mar 12, 2021 11:42:02 AM / by Graham Copley posted in ESG, Oil Industry, Methane

0 Comments

The “adapt or die” headline targeting the US oil industry which was featured in our Daily report yesterday is a bit extreme, especially for an administration that does not believe it can enforce a carbon tax or cap and trade system. If the investment community were to make that statement frankly today it would have more credibility. There is talk about a Senate-sponsored bill to ban methane emissions or at least aggressively penalize them – which would be a better approach. Putting a high price on methane could encourage the use of some interesting small-scale technologies to turn local methane supplies into LNG, or methanol, or ammonia/urea. We have discussed all of these technologies in prior work and are happy to discuss them with anyone interested.

The other more interesting take on “adapt or die” might be “adapt and thrive”, which is likely a more palatable message to give to the energy industry. While the US seems to have limited teeth from a regulatory perspective, the rest of the world does not, and the ability for the US to produce lower carbon fuels may give US producers a competitive edge globally – see our ESG and Climate piece from Wednesday

Plastic Waste Challenges Revisited

Mar 11, 2021 11:20:12 AM / by Graham Copley posted in Recycling, Polymers, Plastic Waste

0 Comments

We are back on plastic waste today, following the IHS World Petrochemical Conference post that collaboration is key to evolving the circular plastics economy, reminding us what the largest challenge is regarding creating a circular plastics economy. Our work on trying to find a waste solution for a specific source material that we have discussed in prior reports has shown us firsthand how difficult it is to get the parties that should be interested in collaborating to talk to each other. While some see the waste problem as an urgent need, generally those that have the waste and are looking for a solution, others that are needed to complete the chain, have the issue far down their list of priorities. Making matters worse is that the margin in the collection, sorting, and then finding the most appropriate home for different streams of waste, is very small unless you are very efficient and/or unless you know that you are getting a disproportionate amount of material that can be upgraded (mechanically recycled) versus downgraded (chemically recycled).

An added complication is that when China was taking waste, there was a payment for the mixed plastic and consequently, many who were involved in that trade are used to being paid for the waste – and have higher expectations of the margins to be shared than are likely available – in other words they want more for the plastic than it is worth locally, especially in a downgrading chemical recycling process.

Source: ResourceRecycling, US Census Bureau

In the chart above, it is likely that the prices being paid for the plastics that are being exported are very low and we have seen instances of local municipalities paying to have waste removes as it is less expensive than landfill – this is a mindset that is needed broadly to generate solutions for waste disposal and the optimal use of the various plastic waste streams. IHS is spot on with its call for greater collaboration, but that collaboration is not at a national level as the waste polymer is spread nationally and internationally and is a problem for local municipalities, counties and if they are coordinated, States, within the US. It is not one instance of collaboration and investment that is needed - it is thousands and while some solution investments may be common, many may not be. This one of the reasons why we believe that the chemical recycling ambitions of the chemical majors are wildly optimistic, given that outside of very large urban centers, they will need to work with hundreds of distinct local groups to get more material into the system.

New Bottlenecks in Recycling

Mar 9, 2021 10:48:23 AM / by Graham Copley posted in ESG, Recycling

0 Comments

Today we focus on recycling and the news that a significant recycler of PET (CarbonLite) has filed for Chapter 11 protection. This is another indication that there is not much money to be made in recycling and it is a little shocking given that the company was focused on PET, which has some of the better recycling rates in the country. The company blames the Bankruptcy on COVID and it is clear that the timing of some major capital commitments related to expansions that were delayed by COVID are part of the problem. While the restructuring is unlikely to see the company liquidated, it appears that the company owes money to customers (pre-payments for the product or for capacity rights – most likely). There could be worse timing for CarbonLite – while the company will look to restructure the debt that it has with customers, it is unlikely that any of them want to run a recycling business and they all need the rPET to meet customer commitments. The negative is that it shines another light on the marginal nature of recycling, even for the better products, and may provide a further incentive for packagers to look to other materials or renewable-based sources
