Waste heat recovery in BASF’s NetZero2050

BASF introduces their NetZero2050 plan. CO2 avoidance potential in electric power and steam production is covered by the “Grey-to-green” and the “Power-to-steam” levers. Other measures are “New technologies,” “Bio-based feedstocks” and “Continuous opex”.

On this slide, the technology levers to reduce BASF’s CO2 emissions have been added in green.
CO2 avoidance potential in electric power and steam production is covered by the “Grey-to-green” and the “Power-to-steam” levers. CO2 emissions in our upstream and, to a lesser extent, downstream plants are addressed by “New technologies,” most of which we are developing as part of our Carbon Management. In addition, “Bio-based feedstocks” will be used seamlessly in our production – partially replacing fossil feedstocks.
“Continuous opex” will be applied at all levels. These operational excellence measures help us to continuously reduce our CO2 emissions. They have the greatest impact at our Verbund sites.

Let’s talk about our levers to reduce BASF’s CO2 emissions in detail. They will help us reduce Scope 1 as well as Scope 2 emissions on our journey to net zero emissions by 2050. I would like to emphasize that we will develop these technologies in partnerships. This allows us to accelerate or generate additional value together. We have announced partnerships with Siemens Energy, as well as with SABIC and Linde. Further partnerships will follow.
Let me briefly comment on temporary measures. To bridge the periods until new technologies are implemented, we will also consider external offsetting measures to a limited extent. If we purchase certificates, we will only use high-quality criteria for external compensation measures, like the WWF Gold Standard.

Let’s now move on to the lever “Power-to-steam.” This is about capturing the energetic potential of waste heat for steam production.

In Ludwigshafen alone, we release waste heat of up to 30 terawatt hours per year into the air or the Rhine river. We do not currently reuse this energy below certain temperatures. Instead, we cool and release cooling water into the Rhine river.
A dedicated team analyzed the current situation and developed a concept to gradually replace steam production at our co-generation plants with heat pumps and steam compressors. This is technically possible – and our analyses show that in many cases, the economics are viable.
Redeploying waste heat from our chemical plants using electric heat pumps on a scale never seen before – this is something we want to realize together with Siemens Energy, first at our Ludwigshafen site and then globally.

KAIST 기계 항공 정기세미나 – 에너지효율과 폐열회수

9.22 KAIST 기계항공공학부 세미나에서 ‘산업부문 에너지효율 향상의 가능성 – 폐열회수를 중심으로’라는 제목으로 강의를 했다. 청중들이 공학적 지식이 뛰어난 분들이라서 이번엔 늘 말하는 정책과 돈 얘기보다는 기술적인 것에 초점을 맞췄다. 그걸 더 관심 있어 할 것 같았다. 제한 시간을 맞추기 위해서 애를 먹었지만 질문도 많이 나오고 반응도 좋았다.
