Enthusiasm for hydrogen as a climate-friendly fuel of the future is everywhere. Hundreds of hydrogen energy projects worth more than $500 billion have been announced, and The International Energy Agency says hydrogen demand could increase sixfold by 2050. Scientists, though, are confident that this leak-prone gas can warm the climate when …

  By Ilissa Ocko and Steven Hamburg Hydrogen emissions from leakage, venting and purging leads to global warming, new research confirms. To take advantage of the potential benefits of switching from fossil fuel systems to hydrogen, we need to keep emissions at a minimum, and doing so will depend on the development of new instruments …

By Morgan Rote Governments and industry around the world are wagering big on hydrogen to solve the climate and clean energy challenge. But woefully insufficient global progress toward establishing strong climate, safety, social and sustainability standards is threatening to compromise the hydrogen market before it has a chance to get started. With the looming threats …

By Jona Koka The Department of Energy’s $7 billion  hydrogen (H2) and $3.5 billion direct air capture hubs program has been hailed as an opportunity to unleash innovation and create a new vision for industrial development. We’ve written about it before and agree this is a great opportunity to set a much higher bar for …

We scoured SXSW, the Austin mega festival, for the coolest climate tech, climate talks, climate ideas. From the sublime to the ridiculous, here are a few of our faves.

Hydrogen hubs in the U.S. could help transform clean industrial development for the better — but only if they're done right.

A new, global hydrogen energy industry is poised to take off, attracting hundreds of billion of dollars in investments. However, hydrogen is an indirect greenhouse gas with a powerful near-term climate impact that is often overlooked. Scientists have raised concerns that hydrogen leaks could negate the expected climate benefits of using hydrogen energy. Real-world data on hydrogen emissions is lacking, but a groundbreaking new technology can help.

Aerodyne instrument provides fast, sensitive readings with 98% accuracy; performance surpasses existing tools, enables mobile measurement from on the ground or in the air for the first time

As the world invests in hydrogen, we need better technology for monitoring hydrogen leaks that contribute to global warming.

There is extraordinary excitement today over zero and low carbon hydrogen. But can it live up to the silver-bullet hype?  To understand the tradeoffs, we compared the total energy required to perform the same tasks using either green hydrogen or direct electrification.

EDF scientist Ilissa Ocko explains what's fact and what's fiction about hydrogen in the movie Glass Onion: A Knives Out Mystery (with spoilers).

Hydrogen is a leak-prone gas that can trigger warming. As the industry grows, now is the time to ask tough questions — before vast systems are built out.

Two New Jersey gas utilities owned by South Jersey Industries, SJI,— South Jersey Gas and Elizabethtown Gas — are petitioning the New Jersey Board of Public Utilities, BPU, for approval to be acquired by JP Morgan-backed investment firm IIF. The companies’ proposal relies on a business model of continued expansion of the natural gas distribution …

The European Commission yesterday approved €5.2 billion in subsidies for hydrogen projects. Recently released research from Environmental Defense Fund outlines the risks of hydrogen’s near-term adverse climate impacts if not carefully deployed.  

Before we go all-in on deploying hydrogen, it’s essential we understand – and prepare for – its potential risks. As hydrogen hub proposals come together, EDF gives nine initial recommendations for federal and state policymakers and hydrogen hub developers to follow.

EDF scientists say leakage risk has been overlooked and understated; warn careful measures are needed to achieve promised advantage

Whether hydrogen turns out to be a climate Jekyll or Hyde will depend, based on soon-to-be published research by Environmental Defense Fund, on how it’s made and how much of it leaks.

By Jake Hiller The U.S. Infrastructure Investment and Jobs Act has set off a flurry of competition among states for a piece of the $8 billion in direct funding and tax credits the law provides for four “hydrogen hubs.” Last week, Louisiana, Oklahoma and Arkansas announced a joint bid, and New Mexico said it will also join the fray. The role proposed …
