Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.

California needs urgent and bold measures to adapt its $59 billion agriculture sector to climate change as the amount of water available for crops declines, according to a new report. The report provides a roadmap for more water capture, storage, and distribution systems that are in harmony with climate projections and ecosystems. It further considers how runoff and groundwater can be used repeatedly as it flows generally from mountainsides to coastal lands.

Researchers have synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.

Our increasing demand for metals and minerals is putting over four thousand vertebrate species at risk, with the raw materials needed for clean energy infrastructure often located in global biodiversity hotspots, a study has found.

An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming.

Newly announced research examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020. This research suggests that drying lake beds are an overlooked but potentially significant source of greenhouse gases, which may further increase due to climate change.

Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.

Coffee beans consumed across the globe come from two species: Coffea arabica and Coffea canephora. By 2050, about 80% of Arabica production is predicted to decrease because of climate change. Researchers are investigating to see if they can find alternative coffee cultivars.
