Long-distance hydrogen interconnectors from an LCOE/LCOS perspective
New research from the U.K. shows the increasing competitiveness of long-distance hydrogen interconnectors over the next three decades. Compared to high-voltage electricity cables, hydrogen interconnectors may soon achieve a much lower levelized cost of storage and their ability to further reduce the final LCOE will depend on how much electrolyzer costs will reduce over the years.
Green hydrogen and the cable-pipeline dilemma
New research from Singapore has found that gas pipelines for the onshore transport of green hydrogen and the cables for the transport of electricity to produce it at a distant location have similar costs at a 4000 km transmission distance. For longer distances, gas pipelines were found to be cheaper than cables, although the electric lines are said to benefit from scaling up and higher utilization. For both options, however, a currently too high hydrogen LCOE remains the biggest barrier to overcome.
