Dutch company Nproxx has unveiled two cutting-edge high-pressure hydrogen storage solutions, the AH620-70 and AH710-70. These innovative tanks have the capability to store gaseous or liquid hydrogen at pressures up to 700 bar. They are versatile, catering to a range of applications such as heavy-duty transport and stationary energy storage. Crafted from a composite material with a plastic liner, these Type 4 tanks are compatible with both H2 internal combustion engines and fuel cell powertrains, showcasing their adaptability. The larger AH710-70 tank boasts a diameter of 69.85 cm (27.5 inches) and a length of 245.3 cm (96.6 inches), holding up to 22.2 kg of hydrogen, while the smaller AH620-70 can store 12.4 kg. When equipped with four AH710-70 tanks, a heavy-duty truck could potentially achieve a range of approximately 965 km (600 miles). Both tank variants feature a neck-mounted valve system, streamlining the refueling process to around 15 minutes. In a strategic move, Nproxx partnered with Cummins in 2020 to establish a joint-venture focusing on H2 storage tanks. There are indications that these new tanks could be integrated into offerings developed by Accelera by Cummins, signaling further advancements in the hydrogen storage sector.
