As hydrogen can escape even more easily than methane through the tiniest holes, cracks, and weld seams, the transport and eventual storage of this gas is one of the major barriers to wider adoption of this gas as a fuel and feedstock. Hydrogen permeation and embrittlement only exacerbate the problem. <\/strong><\/p>\n<p>The leakage rate for natural gas is already higher than what the Environmental Protection Agency estimates. Research published in the journal <em>Science<\/em> found that leaks in the US methane supply chain in 2015 was 2.3% of gross production, about 60% higher than the EPA\u2019s inventory estimate (<a href=\"https:\/\/www.science.org\/doi\/10.1126\/science.aar7204\" rel=\"external\" target=\"_blank\">Alvarez et al., 2018<\/a>).

(As a comparison, carbon dioxide has a GWP of 1 and methane has a GWP of 27-30)<em>.\u00a0<\/em>Thus, in order to realize the green benefits of a hydrogen economy, governments and the chemical industry must solve the problem of leakage during transport and storage.<\/p>\n<h2><span>How to Prevent Hydrogen Leaks <\/span><\/h2>\n<p>To minimize the risks of hydrogen leakage, we must first fully understand the problem and its extent. The chemical industry should take the following steps:<\/p>\n<ul>\n<li>Develop instruments that can measure hydrogen concentrations on a parts-per-billion scale to systematically quantify leakage.<\/li>\n<li>Use climate metrics to illustrate the extent to which hydrogen leakage impedes reaching climate goals in the near term.<\/li>\n<li>Consider probabilities of H<sub>2<\/sub> leakage in decisions about where and how to use hydrogen.<\/li>\n<li>Reduce transportation needs by locating production and deployment sites nearer each other.<\/li>\n<li>Develop best practices for minimizing hydrogen leakage by adapting the measures currently employed to reduce leakage of other gases, while keeping in mind the unique chemical properties of hydrogen.<\/li>\n<\/ul>\n<p>This article follow \u201c<a href=\"https:\/\/blog.wika.com\/us\/\/applications\/hydrogen-a-beacon-of-hope-for-the-chemical-industry\/\">Hydrogen: A Beacon of Hope for the Chemical Industry<\/a>.\u201d Next in the series: \u201cEnergy Expenditure as a Factor in H<sub>2<\/sub> Transport and Storage.\u201d<\/p>\n<p>&nbsp;<\/p>\n<p><span>[contact-form-7 id=&#8221;14552&#8243; title=&#8221;Blog Contact Form&#8221;]<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Leaks are a pernicious issue in natural gas pipelines.
