Rystad Energy has joined BloombergNEF with a significant forecast for gray and blue hydrogen off the back of Russia’s invasion of Ukraine. According to the analysts, the impact of the war has sent prices of fossil fuel-tied forms of hydrogen production surging, leaving the gradual but consistent downward price trend of green hydrogen now looking remarkably competitive.

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an efficiency of 80.26% and an LCOS of €0.116/kWh.

A report published by Irena hints the world’s politicians will have to get to work immediately to avoid another generation of fossil fuel-fired hydrogen, ammonia, and methanol plants being set up to run into the second half of the century.

The Zeppelin project is expected to generate more than 135,000 tons of green hydrogen from 99 million tons of waste and 50 million tons of municipal wastewater.

Solarpack’s click&go system relies on solar panels in its own projects, rather than in the homes of consumers, so households can consume renewable energy remotely. Clients can buy energy produced from their remotely owned panels for around €30 ($32.98)/MWh.

Spanish engineering company Sener has developed a software that analyzes different combinations of panels, trackers or tables, inverters and storage systems, as well as construction costs, depending on the market situation at any given time and the client’s preferences.

Scientists in Spain have designed a BIPV forced ventilated facade that can be used as support for heating and a domestic hot water (DHW) building system based on air source heat pumps (ASHPs). In the proposed system configuration, the heat pump is expected to cover building heating demand at all times, regardless of the performance of the solar array.

The Agua+S project under development in the Spanish region of Andalucia is aimed at combining a desalination plant, a pumping station network, and an onshore, floating photovoltaic plant in a single project design. According to its developers this is the first time that these three facilities have been combined together in a fully reproducible design that could be replicated in any river basin that has a reservoir and is close to the coast, to produce fresh water for both irrigation and human consumption.

OnSight Technology has developed a tele-operated vehicle to clean solar arrays. It is equipped with a radiometric thermal imaging camera and an optical zoom camera backed by artificial intelligence. It has a range of 12 hours and a speed of 1.6 km per hour.

A Spanish consortium is equipping one of Madrid’s largest metro and bus stations with a hybrid system that combines PV, geothermal pumps, and vanadium redox flow batteries to provide cooling and heating.
