While consuming hydrogen &mdash; such as in a hydrogen fuel cell vehicle &mdash; only produces water as a byproduct, the process of creating that hydrogen in the first place can have a&nbsp;<a class="af nf" href="https://www.weforum.org/agenda/2021/07/clean-energy-green-hydrogen/" target="_blank" rel="noopener ugc nofollow">substantial carbon footprint</a>.</p>
<p id="5746" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">The staggering truth is that 96% of the current hydrogen production is&nbsp;<a class="af nf" href="https://rmi.org/wp-content/uploads/2020/01/hydrogen_insight_brief.pdf" target="_blank" rel="noopener ugc nofollow">grey hydrogen</a>, which emits all greenhouse gasses produced directly into the atmosphere.

<p id="9d64" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">Yet amidst the hydrogen rainbow, there&rsquo;s also the much-heralded green hydrogen &mdash; produced by splitting water (rather than fossil fuels) in&nbsp;<a class="af nf" href="https://www.weforum.org/agenda/2021/07/clean-energy-green-hydrogen/" target="_blank" rel="noopener ugc nofollow">renewably-powered electrolyzers</a>.

<p id="4385" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">The significant development of numerous green hydrogen projects is expected to accelerate output in the near future.

And by leveraging renewable energy sources like industrial solar, green hydrogen has the ability to accomplish all the above, without the carbon footprint of the traditional grey hydrogen that currently dominates the market.</p>
<p id="96b9" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">But first, green hydrogen needs to dramatically scale up production to meet global demand, while equally racing down the cost curve to compete with much cheaper grey hydrogen.</p>

<p id="5a4c" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">In the United States specifically, there&rsquo;s ambition on the green hydrogen front as well.

The ambitious project will rely on 60 gigawatts of behind-the-meter solar and onshore wind power, supplemented by renewable energy drawn from the ERCOT grid during periods of low power prices. Hydrogen City is anticipated to yield an annual output of 3 million tonnes of green hydrogen per year.</p>
<p id="f189" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">The Port of Corpus Christi Horizons Clean Energy Hub and the Trans Permian H2Hub have joined forces to compete for federal grant funding, aiming to establish a&nbsp;<a class="af nf" href="https://oneh2.com/texas-paves-the-way-for-a-regional-hydrogen-hub/" target="_blank" rel="noopener ugc nofollow">regional hydrogen hub</a>&nbsp;in Texas.

In 2050, it is anticipated that 21 million metric tons of clean hydrogen will be produced, 180,000 potential jobs will be created, $100 billion will be added to the state GDP, and 220 million metric tons of global carbon dioxide will be abated in Texas.</p>
<p id="38a6" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">The outlook for Texas&rsquo; green hydrogen projects is increasingly positive. Coupled with decreasing electrolyzer costs, large-scale solar can power Texas&rsquo; budding green hydrogen initiatives, helping to ensure the 2050 vision becomes a reality.</p>
<h2 id="949b" class="ng nh fo be ni nj nk nl nm nn no np nq nr ns nt nu nv nw nx ny nz oa ob oc od bj">Net-metered industrial solar can enable cost-effective green hydrogen production</h2>
<p id="2aff" class="pw-post-body-paragraph mh mi fo mj b mk oe mm mn mo of mq mr ms og mu mv mw oh my mz na oi nc nd ne fh bj" data-selectable-paragraph="">The increasing deployment of electrolyzer capacity necessitates a significant supply of affordable renewable energy to unlock the full potential of green hydrogen. However, achieving truly green hydrogen requires more than relying solely on renewable sources. It is crucial to ensure that the all-in-power costs for hydrogen electrolyzers are extremely low to enable green hydrogen production costs to compete with the prevailing grey hydrogen that currently dominates the global market.</p>
<p id="1b55" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">In this regard, net-metered industrial solar in Texas emerges as a leading solution. It not only offers affordable solar power but also virtually eliminates demand charges. With electricity-driven production processes for green hydrogen (i.e., water splitting with electrolyzers), this is a big deal.</p>
<p id="7d69" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">Although net-metered industrial solar is technically front-of-the-meter, these projects are also directly connected to the electrolyzer. Because of this direct power supply, owners can feel confident about qualifying for the&nbsp;<a class="af nf" href="https://uscode.house.gov/view.xhtml?req=granuleid%3AUSC-prelim-title26-section45V&amp;num=0&amp;edition=prelim" target="_blank" rel="noopener ugc nofollow">green hydrogen tax credit</a>&nbsp;available through the Inflation Reduction Act. This is not necessarily the case with other renewable energy investment options (like virtual power purchase agreements, for example), where policymakers are still coming to a consensus around energy co-timing requirements.</p>
<p id="34ec" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">Additionally, Industrial Sun&rsquo;s approach enables a financeable third-party ownership structure that avoids the need for companies to commit CapEx to the project, which would otherwise make for a substantial upfront investment. This allows for the best of both worlds: the benefits of direct power without the challenges of direct ownership.</p>
<p id="e199" class="pw-post-body-paragraph mh mi fo mj b mk ml mm mn mo mp mq mr ms mt mu mv mw mx my mz na nb nc nd ne fh bj" data-selectable-paragraph="">These unique characteristics position net-metered industrial solar in Texas as a comprehensive solution that meets all the necessary criteria for powering electrolyzers with massive amounts of cheap renewable energy, while effectively realizing green hydrogen&rsquo;s potential. By leveraging net-metered industrial solar, the goal of affordable green hydrogen production becomes attainable, paving the way for a more sustainable and competitive hydrogen industry.</p>
