We decarbonize heavy duty logistics

Tog­e­ther for more sus­taina­bi­li­ty. We all have dif­fe­rent back­grounds, but are united in the cau­se: decar­bo­ni­s­ing port logi­stics with hydro­gen as a rene­wa­ble ener­gy source. Hed­da Graf, Marie Kris­tin Stuss­nat, Mara Linn Becher, Leif Cars­tens and Axel Marth from left to right, as well as Karin Deba­cher (not on the picture).

Leif Carstens

Leif has been in char­ge of the Clean Ports & Logi­stics Inno­va­ti­on Clus­ter sin­ce March 2023. As an envi­ron­men­tal sci­en­tist with a focus on the inter­faces bet­ween alter­na­ti­ve pro­pul­si­on tech­no­lo­gies and ener­gy sys­tems, he brings exten­si­ve expe­ri­ence as a pro­ject mana­ger in the field of elec­tro­mo­bi­li­ty and hydro­gen from major inter­na­tio­nal projects.

Marie-Kristin Stussnat

Marie has been sup­port­ing the appli­ca­ti­ons depart­ment sin­ce August 2024. She brings exten­si­ve prac­ti­cal expe­ri­ence to this role. She is fami­li­ar with the port, its ter­mi­nals and struc­tures, as well as the equip­ment, which she has ope­ra­ted hers­elf for many years. She has fur­ther expan­ded her exper­ti­se in recent years by stu­dy­ing logi­stics management.

Axel Marth

Axel joi­n­ed our team as a pro­ject mana­ger in August 2024 and is respon­si­ble for import and dis­tri­bu­ti­on issues. Befo­re joi­ning HHLA, he con­duc­ted rese­arch on the elec­tro­che­mi­cal sto­rage of hydro­gen at the Helm­holtz Insti­tu­te for Rene­wa­ble Ener­gy in Erlan­gen-Nurem­berg. His core topics were elec­tro­che­mi­cal liquid orga­nic hydro­gen car­ri­ers (EC-LOHCs) and the production/use of hydrogen.

Karin Debacher

Karin Deba­cher star­ted as a pro­ject mana­ger at Ham­bur­ger Port Con­sul­ting GmbH HPC in 2015. The­re she mana­ged many dif­fe­rent inter­na­tio­nal pro­jects and four years later moved to HHLA in the Exe­cu­ti­ve Board Pro­jects and Busi­ness Deve­lo­p­ment divi­si­on. At HHLA, she has been in char­ge of the Hydro­gen divi­si­on sin­ce 2020.

Volker Windeck

Vol­ker moved from HPC to HHLA in 2016 and has been working as a seni­or pro­ject mana­ger in the Exe­cu­ti­ve Board Pro­jects & Busi­ness Deve­lo­p­ment depart­ment sin­ce 2020. The indus­tri­al engi­neer, who holds a doc­to­ra­te, pre­vious­ly gai­ned inter­na­tio­nal expe­ri­ence in port and ter­mi­nal plan­ning at HPC. With his MBA in Lea­der­ship & Sup­p­ly Chain Manage­ment, he com­bi­nes ope­ra­tio­nal imple­men­ta­ti­on skills with a flair for inno­va­ti­on. Sin­ce June 2025, Vol­ker has ser­ved as the head of hydro­gen pro­jects at HHLA.

Hedda Graf

Hed­da began a dual degree pro­gram­me in logi­stics manage­ment at HHLA in 2022. She com­ple­ted the pro­gram­me after many assign­ments in various HHLA depart­ments and at the Ham­burg School of Busi­ness Admi­nis­tra­ti­on (HSBA). In Octo­ber 2025, Hed­da joi­n­ed our team and is working with us to advan­ce HHLA’s hydro­gen initia­ti­ve, which invol­ves inves­ti­ga­ting and test­ing the con­ver­si­on of die­sel-powered ter­mi­nal equip­ment. The­se include the ‘Clean Port and Logi­stics’ clus­ter and H2LOAD.

We look forward to your questions
