Japan’s Green Growth Strategy indicators a dedication to net-zero greenhouse gas emissions by 2050—and hydrogen produced from renewable power can play an necessary position in this shift. A workforce of researchers from Harvard University, Shandong University, China University of Petroleum Beijing and Huazhong University of Science and Technology have explored the potential of producing hydrogen by electrolysis utilizing energy generated from offshore wind in China.

“This research helps build the case that it is not only possible for Japan to meet the formidable challenge of transitioning to net-zero emissions, it also could be cost-competitive,” explains lead creator Shaojie Song, Research Associate in the Harvard-China Project on Energy, Economy and Environment in the John A. Paulson School of Engineering and Applied Sciences at Harvard University. “Our research shows that Chinese-produced could be delivered at a volume and cost consistent with Japan’s future projections.”

The workforce analyzed the potential for a inexperienced hydrogen provide chain to Japan delivered from offshore wind produced in China on an hourly foundation from each Chinese coastal province, contemplating a number of attainable wind funding ranges, electrolysis applied sciences and transport mechanisms. The generated hydrogen could possibly be delivered to Japan both as , sure to a chemical provider corresponding to toluene, or as a element of ammonia.

The researchers decided that offshore wind energy from China might present probably as a lot as 12 petawatt-hours of electrical energy yearly. They modeled the associated fee implications of the offshore wind location; chemical conversion processes; and storage, transport, and supply strategies. The workforce discovered that Chinese sources might provide cost-competitive hydrogen to Japan for 2030 even when offshore wind deployment follows a high-cost situation.

“Green hydrogen production in China would not only benefit Japan’s net-zero transition, but it also has the potential to benefit both country’s plans for future carbon neutrality,” explains creator Michael B. McElroy, Gilbert Butler Professor of Environmental Studies at Harvard University and Chair of the Harvard-China Project. “A closer commercial relationship between China and Japan could facilitate comparable cross-fertilization of energy advancements like fuel cell technologies. And green hydrogen production from in China has the potential to expand also to South Korea, which has similarly ambitious plans for investments in expanded use of hydrogen as a fuel and feedstock.”

The analysis was printed in Nature Communications.
