From the Sector

Freudenberg Performance Materials – the Freudenberg Group’s nonwovens specialist – was hosting a meeting of the German National Hydrogen Council at the Freudenberg headquarters in Weinheim, Germany, on September 16. As a leading global supplier of technical textiles, Freudenberg Performance Materials provides fuel cell components for mobility applications and for electrolyzers used to produce CO₂-free hydrogen.

The German National Hydrogen Council was appointed by the German government and acts as an independent, non-partisan advisory board. The council board currently consists of 25 high-ranking experts in the fields of economy, science and civil society. The objective is to assist and advise the State Secretaries’ Committee on Hydrogen in the further development and implementation of Germany’s National Hydrogen Strategy. Council meetings are hosted by one of the board members to enable the council to deepen its knowledge of the relevant technologies, value chain roles and challenges. Dr. Silke Wagener is a member of the council board, and represents the Freudenberg technology group, giving input on suppliers’ know-how as well as contributing her decades-long expertise in technological solutions for the hydrogen industry.

During a tour of the factory organized for the council board members, Freudenberg Performance Materials explained the development and production of performance-critical gas diffusion layers manufactured from carbon fiber-based nonwovens for fuel cells and porous transport layers for electrolyzers. The tour highlighted the potential for improvements from a supplier’s perspective, such as the need for very timely exchange and collaboration along the value chain. Functioning, unbroken and scalable value chains, in parallel with the development and scaling of hydrogen infrastructure, are key prerequisites for the hydrogen industry to fulfill its vital role in the transformation to climate neutrality.

Gas diffusion layers are one of the main components at the heart of the fuel cell. Their function is to transport gases and liquids in the cells. They have a significant impact on system performance and costs, and are indispensable for the functioning of fuel cells. The same applies for porous transport layers that are the key component of electrolyzers for the CO₂-free production of what is called green hydrogen.

Fuel cells in combination with green hydrogen are an important technology for CO₂-free mobility, in particular with reference to buses, heavy-duty trucks and trains. Other uses include stationary applications such as stationary power generation or heat generation in buildings or industry.
Apart from mobility, green hydrogen also plays a key role in climate-neutral energy supplies in the industrial sector, particularly in the chemical and steel industries.

• Sales increase of 10.7% to €549.8 million in the first half of 2022
• EBITDApre improves by 22.6%, higher than the increase in sales, to €87.9 million
• Positive business development, price increases and strict cost management led to forecast increase on June 7, 2022

Despite uncertain general conditions in the first six months 2022, SGL Carbon's business model is proving its resilience. After €270.9 million in Q1 2022, SGL Carbon was able to increase sales to €278.9 million in Q2. Accordingly, sales for the first half of 2022 amount to €549.8 million, which corresponds to a sales plus of €53.1 million or 10.7% compared to the same period of the previous year.

The increase in sales was driven in particular by customers in the semiconductor industry and growth in the industrial applications market segment. Demand from the automotive and chemical industries was also encouraging.

EBITDApre, as one of the Group's key performance indicators, improved by €16.2 million (+22.6%) to €87.9 million (H1 2021: €71.7 million). Consequently, the EBITDApre margin increased from 14.4% to 16.0%. In addition to the higher utilization of production capacities due to higher sales, the improvement in earnings was also driven by the largely successful passing-on of higher raw material and energy costs to customers as well as savings from the transformation program.

EBITDApre does not include positive one-off effects and non-recurring items totaling €10.6 million (H1 2021: minus €5.2 million). As a result, EBIT in H1 2022 increased significantly from €38.3 million to €69.6 million. Taking into account the financial result of minus €16.6 million (H1 2021: minus €14.0 million), consolidated net income for the first six months of the current fiscal year amounted to €48.8 million, compared to €17.9 million in the prior-year period.

Business Units
With an increase in sales of €22.2 million (+10.0%) to €243.4 million, the Graphite Solutions (GS) business unit made a major contribution to SGL Carbon’s sales growth. In particular, continued high demand from customers in the semiconductor sector, which represents approximately one third of the segment's sales, led to the positive business development in GS. As a result of the predominantly high-margin business, EBITDApre at GS improved by 22.7% to €54.0 million.

The Process Technology (PT) business unit benefited from the good order situation in the chemical industry in H1 2022 and consequently increased sales to €49.2 million (H1 2021: € 40.8 million). EBITDApre also improved from €0.1 million in the prior year’s first half to €4.1 million in H1 2022.

The Carbon Fibers (CF) business unit benefited in the 1st half 2022 from final deliveries to a major automotive manufacturer whose contract expired as scheduled on June 30, 2022. Segment sales increased by 5.8% year-on-year to €176.0 million. In contrast, EBITDApre at CF decreased by €4.2 million to €28.2 million despite the good order situation and successful price increases. It should be noted that CF was impacted by a special effect from energy derivatives for price hedging in the amount of €9.2 million in the first quarter of 2022.

With an increase in sales of 15.6% to €69.6 million, the Composite Solutions (CS) business unit continued its upward trend. The specialist for customized component solutions for the automotive industry improved its EBITDApre from €5.7 million in the first half of 2021 to the current €9.7 million, based in particular on price and volume effects.

Balance sheet figures
Working capital rose by 11.7% to €381.1 million as of June 30, 2022. This was mainly due to higher inventories (€ +73.9 million) and an offsetting increase in trade payables (€ +29.0 million). A targeted build-up of inventories in critical raw materials due to disruptions in transport routes and the recent Covid lockdown in Shanghai were some of the reasons for the higher inventory levels.

SGL Carbon's net financial debt slightly increased by €6.6 million to €212.9 million as of June 30, 2022 (Dec. 31, 2021: €206.3 million), which was due to a lower free cash flow of €7.5 million for H1 2022 (H1 2021: €56.6 million).

Guidance increase
On June 7, 2022, SGL Carbon raised its sales and earnings guidance for fiscal year 2022. The company now expects sales of €1.1 billion (previously: around €1.0 billion) and EBITDApre of €130 - 150 million (previously: €110 - 130 million). Based on the pleasing business development, realized price increases, a stringent cost management, and taking into account the currently known risks, SGL’s management expects to achieve the earnings forecast for 2022 at the upper end of the stated range.

SHIMA SEIKI MFG., LTD. of Wakayama, Japan, along with its Italian subsidiary SHIMA SEIKI ITALIA S.p.A., will be participating in the Techtextil exhibition in Frankfurt, Germany from the 21st till the 24th of June 2022.

On display will be SHIMA SEIKI’s latest innovation in flat knitting technology as applied to the field of technical textiles—a prototype weft knitting machine capable of multi-axial yarn insertion. Fabrics produced on this machine use inlay technique for the production of hybrid textiles that combine the stretch characteristics of knitted fabrics with the stability of woven textiles, suited to various technical applications. To this, warp yarn is inserted to further expand its capability to produce 3D-shaped carbon fiber and composite preforms directly on the machine. This is made possible by taking advantage of the fact that flat knitting as a textile production method is capable of producing end products that are shaped-to-form and with added thickness. Compared to current methods of preform production, savings in post-processing time, material, labor and associated costs are immense, realizing efficient and sustainable production. SHIMA SEIKI’s own yarn unwinding technology is also used for optimum yarn feed and tension for use with technical yarns that are otherwise difficult to knit. Industrial textile samples knit on the multi-axial machine will also be available for examination on-site.

SHIMA SEIKI's SDS®-ONE APEX4 3D design system will be available for demonstrations as well. Of particular interest should be its ultra-realistic simulation capability that realizes Virtual Sampling. When countless variations must be evaluated before arriving at a final design, virtual product samples can be used to streamline the decision-making process by minimizing the enormous amount of time, cost and material normally associated with producing actual samples for each variation. When approved, the same data can be converted to machine data for immediate knitting, significantly reducing lead times.
