With hydrogen increasingly gaining favor as an attractive fuel option for aircraft more attention is turning to how it can be supplied in sufficient volumes, and also how it can be produced in a way that supports the industry’s zero-emissions objectives. The aviation sector needs firm assurances that supplies will be cost-effective and meet the so-called ‘green hydrogen’ mark for being environmentally sustainable, taking account of the full production process.
Last month Nexa Capital Partners, a financial group active in the advanced air mobility sector, announced it is joining forces with energy technology group Element 1 to advance the adoption of the latter’s methanol-to-hydrogen generators for fuel cell-based powerplants for electric aircraft and other applications. The partners maintain that methanol, also known as methyl alcohol, is a highly efficient hydrogen carrier, delivering a greater volume of recoverable hydrogen fuel than an equivalent volume of liquid hydrogen. As for its green credentials, they say that methanol produced from biomass, wind, and other processes cuts carbon dioxide emissions by up to 95 percent compared with conventional fuels, and cuts nitrogen oxide emissions by up to 90 percent.
