power-to-gas

Researchers at Stanford University have developed a type of electrode which is highly resistant to salt corrosion, therefore allowing them to produce hydrogen using seawater. Applied at a larger scale, this development could potentially cut the cost of power-to-gas applications by greatly increasing the amount of water available.

Toyota Australia will transform its former manufacturing site in West Melbourne into a renewable energy hub to produce green hydrogen with the help of funding from the Australian Renewable Energy Agency (ARENA). In other hydrogen-related news, researchers at UNSW Sydney with partners H2Store have received a $3.5 million investment from Providence Asset Group to develop a hydrogen residential storage.

A report commissioned by the European Climate Foundation suggests a fossil fuel-free energy system in Europe by 2050 should largely rely on smart electrification and energy efficiency. Green hydrogen deployment, the report finds, would require prohibitively expensive infrastructure investment.

An international team of economists says power-to-gas may already generate hydrogen at costs competitive with fossil fuel power plants in Germany and Texas, provided certain production output levels are not exceeded. If medium and small power-to-gas is competitive, large-scale should be viable by 2030.

In the Infrastructure Outlook 2050 study, Gasunie and TenneT say ambitious EU climate targets can only be reached through deeper integration of the power and gas infrastructure, and with power-to-gas technologies supporting renewables. The most bullish scenario for solar states how storage and power-to-hydrogen capacity could be crucial to meet seasonality in supply and demand.

The €150 million project is entering the approval phase. Using the new facility, expected by 2023, the two companies will test how electricity from renewable energy can be converted into green hydrogen and green methane via electrolysis.

The opportunities for power-to-gas have long interested the solar community, but large-scale projects have been exceptionally rare. The outgoing CEO of SolarPower Europe, James Watson, has presided over a transformative period at the organization, and departed in January to head up Eurogas – right at the point the region’s solar sector is set for revival. Advancing a power-to-gas agenda, Watson tells pv magazine editor in chief Jonathan Gifford, will be a big part of his new challenge.

The “Project Centurion” will allow the testing of ITM Power’s Proton Exchange Membrane (PEM) electrolyser at Inovy’s Runcorn Site, where hydrogen is being produced as a co-product of the chlor-alkali process.

The Spanish power provider developed the pilot project with the Institut de Recerca en Energia de Catalunya and German spin-off Ineratec. Meanwhile, the European Power to Gas Platform has issued a paper demanding more regulatory certainty for power-to-gas, and to include it as an alternative in the cost-benefit analysis for grid extensions.

Toshiba has begun a large power-to-gas demonstration project in Japan. In spite of low efficiency and high prices, hydrogen is researched by many companies. In this demo, facilities are powered by Toshiba’s fuel cells, which receive hydrogen from an adjacent hydropower hydrogen generation facility.
