The Hydrogen Stream: Heavy-duty hydrogen refueling station in Germany

Everfuel has signed a deal to build a hydrogen refueling station in Germany, while the European Hydrogen Backbone initiative has accelerated its own program to produce 20.6 million tons of renewable, low-carbon European hydrogen. Separately, the UK government published its hydrogen investor roadmap to 2030.

Sweden’s first rock cavern for green hydrogen storage takes shape

Vattenfall, SSAB and LKAB have reached the halfway point in the construction of a rock cavern storage facility in a coastal city in northern Sweden. The 100-cubic-meter facility is being constructed 30 meters below ground and will begin storing green hydrogen next year.

Snow, ice-repellent coating for solar panels

Researchers in Sweden are currently testing three kinds of coatings — hydrophobic, superhydrophobic and slippery liquid-infused porous surfaces. The goal of the new technology is to halve ice adhesion compared to standard modular glass and ensure 96% light transmittance.

Thermally integrated PV-electrolyzer with 9.1% solar-to-hydrogen efficiency

A Swedish research group has developed a device combining CIGS thin-film solar modules and an alkaline electrolyzer based on a trimetallic cathodic catalyst made of nickel, molybdenum, and vanadium (NiMoV) and an anode made of nickel oxide (NiO). The electrolyzer achieved an average solar-to-hydrogen (STH) efficiency of 8.5% for stable operations during 100 hours.

New, powerful way to make micro supercapacitors

Swedish researchers have developed a novel way to manufacture micro supercapacitors, also known as system-on-a-chip, so they are compatible with other components in system circuits and can be easily tailored for different uses.

Large scale solar reaches €0.02737-04939/kWh LCOE in Sweden

New research from Sweden showed that financing conditions and the choice of location are crucial factors in reducing the levelized cost of energy for utility scale solar parks built without subsidies in the Scandinavian country. According to the researchers, the project with the lowest LCOE in Sweden, of €0.02737/kWh, is a plant with an expected lifetime of 45 years, a 2% annual degradation rate, capex of €703,758 per megawatt installed, a yearly fixed operations and maintenance cost of €11,277 per megawatt, and a nominal weighted average cost of capital per annum of 0.2%.

‘The technology and the capital are available, but the market simply lacks execution capacity’

1Komma5° has acquired a majority stake in Swedish solar installation provider Cellsolar AB. This is the sixth acquisition of the recently founded Cleantech startup which wants to open the installation sector for the capital market in order to allow rapid growth.

Novel methodology to identify solar-suitable roofs

Swedish scientists developed a three-step method that integrates techniques used for the automatic extraction of buildings along with their underlying roof faces, as well as the identification of utilizable rooftop areas for solar arrays. The novel methodology is claimed to avoid overestimating actual potential of buildings for PV deployment.
