Polenergia, a leading private energy group in Poland, has made significant strides in the green hydrogen sector. The company conducted successful hydrogen co-combustion tests in Podkarpacie, achieving a 15% hydrogen concentration, a notable feat for the industry. These tests were pivotal in demonstrating the feasibility of greening energy production through hydrogen integration. Polenergia's ambitious H2HUB Nowa Sarzyna project, featuring a 5 MW capacity electrolyzer for green hydrogen production, has obtained a crucial building permit. This project aims to revolutionize emission-free transport, greening heat production, and eventually generating clean electricity. The company's strategic focus on zero emissions by 2040 aligns with its commitment to innovation and sustainability in Poland's energy sector. Partnerships with key companies like Hystar AS have advanced the production technology, including the completion of electrolyzer stacks made with advanced materials like iridium and platinum. Funding from the National Fund for Environmental Protection and Water Management has further supported the project's development. The progress made by Polenergia signifies a significant step towards a more sustainable and environmentally friendly energy landscape in Poland.
