green hydrogen

Achieving cost-competitiveness for green hydrogen produced via water electrolysis using intermittent renewable energy sources remains a significant challenge. Researchers from LUT University in Finland have shown that considerable cost reductions can be achieved by simultaneously optimizing plant control and design, based on specific hydrogen demand targets and local weather conditions.

Through a rigorous approach, with more than 4,000 simulations and a detailed analysis of each scenario, Enertis Applus+ offers a roadmap for understanding where, how, and under what conditions green hydrogen can be produced at competitive costs.

Researchers have designed a novel multigeneration energy system that provides five outputs, namely electricity, hydrogen, cooling, heating, and hot water. The system is mainly powered by a solar heliostat system and incorporates compressed air and pumped hydro storage technologies for storing surplus power.

BloombergNEF and Wood Mackenzie analysts spoke with pv magazine about the EU’s €992 million ($1.04 billion) hydrogen tender that drew record-low bids thanks to strong design incentives. They outlined the factors behind the tender’s competitiveness but cautioned that not all awarded projects may move forward.

South African utility Eskom is searching for a developer to engineer, procure and construct a renewable green hydrogen facility at its research unit in Johannesburg. The deadline for applications is June 27.

The International Electrotechnical Commission (IEC) highlights the transformative potential of green hydrogen and hydrogen-derived ammonia for decarbonizing the maritime industry. According to its experts, hydrogen could be soon be used as a maritime fuel, as ongoing innovation is slated to make hydrogen storage and transportation more viable over time.

Scientists have developed a system that harvests rainwater running off PV panels for household use or hydrogen production. Their analysis showed that, in the southern Sahel, the system can meet both the energy and water requirements for electrolysis, with surplus rainwater covering up to 50% of a household’s daily water demand.

After a global flurry of green hydrogen announcements, fuel cell company insolvencies, and a sharp market reassessment, solar developers are questioning near-term green hydrogen demand. pv magazine’s Carrie Hampel takes a look at the international landscape.

Westwood Global Energy Group says just 17% of the European Union’s hydrogen projects will advance without intervention, while Smartenergy says Spain’s Orange.bat project has cleared a key environmental hurdle and will launch in May 2028.

Akasaka Heating & Cooling Supply says it will use green hydrogen produced at an unspecified location in Japan to produce heat and electricity for its Akasaka 5-chome district heating system in central Tokyo.
