Record solar hydrogen production with concentrated sunlight

Researchers have created a smart device capable of producing large amounts of clean hydrogen. By concentrating sunlight, their device uses a smaller amount of the rare, costly materials that are required to produce hydrogen, yet it still maintains a high solar-to-fuel efficiency. Their research has been taken to the next scale with a pilot facility installed on the EPFL campus.

From coal to gas: How the shift can help stabilize climate change

A transition from coal-based energy to cleaner-burning gas has long been viewed as a staple of many climate action plans, despite concerns over leakage and possible harmful emissions. A recent study finds that not only is such a shift central to meeting climate targets and stabilizing global temperature rise, but that the benefits of cleaner-burning gas outweigh its possible risks.

World’s fastest hydrogen sensor could pave the way for clean hydrogen energy

Hydrogen is a clean and renewable energy carrier that can power vehicles, with water as the only emission. Unfortunately, hydrogen gas is highly flammable when mixed with air, so very efficient and effective sensors are needed. Now, researchers present the first hydrogen sensors ever to meet the future performance targets for use in hydrogen powered vehicles.

Renewables are a better investment than carbon capture for tackling climate change

Solar panels and wind turbines coupled with energy storage offer a better hope for tackling climate change than trying to capture carbon from fossil fuel power stations, according to new research. New research shows that resources that would be spent on developing and installing carbon capture technologies would be better invested in creating more solar panels and wind turbines and focusing on developing energy storage options to support these instead.
