Japan has been in the forefront of research and development concerning the use of hydrogen energy for vehicles since the government committed itself about 20 years ago to creating a "hydrogen society." Professor Nobuhiro Yoshikawa of the Institute of Industrial Science, the University of Tokyo (UTokyo-IIS), is conducting research aimed at developing hydrogen-powered fuel cell vehicles (FCVs), which are seen as ideal eco-friendly cars because they do not emit carbon dioxide. His approach is to help develop light, low-cost fuel tanks that can hold high-pressure hydrogen. Such fuel tanks are a key component in fuel cell cars, the widespread adoption of which is essential if Japan wants to attain carbon neutrality by 2050.
