Gas will still be a part of the mix but only to address exigencies.

Energy prices In Europe are at an all-time high. While the situation is not expected to last forever, even after gas prices reach some degree of moderation, the cost of generating power using solar photovoltaics will drop so low that it will be 10 times cheaper, a report from an energy research company said.

Europe has always relied on gas-fired power stations for its energy demands. The geopolitical tension over Ukraine has resulted in Russia dropping its gas exports, which have directly impacted the region’s energy cost.

Scientists from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and Lawrence Berkeley National Laboratory (Berkeley Lab) are providing researchers with a guide to how to best measure the efficiency of producing hydrogen directly from solar power.

Photoelectrochemical (PEC) water-splitting, which relies on sunlight to split water into its component elements—oxygen and hydrogen—stands out as potentially one of the most sustainable routes to clean energy. Measurements of how efficient the PEC process is on an identical system can vary wildly from different laboratories, however, from a lack of standardized methods. The newly developed best-practices guide published in Frontiers in Energy Research is intended to provide confidence in comparing results obtained at different sites and by different groups.

The publication provides a road map for the PEC community as researchers continue to refine the technology. These best practices were verified by both laboratories via round-robin testing using the same testing hardware, PEC photoelectrodes, and measurement procedures. Research into photovoltaics has allowed a certification of cell efficiencies, but PEC water-splitting efficiency measurements do not yet have a widely accepted protocol.

How resilient are solar panels in the face of extreme weather events?

Guest contributor Jane Marsh explores the current capability of solar panel technology in the face of increasing extreme climate events.

Technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy was once considered science fiction. Now it is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of California Institute of Technology (Caltech) researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed. They could even send it to places that currently have no access to reliable power.

“This is an extraordinary and unprecedented project,” says Harry Atwater, an SSPP researcher and Otis Booth Leadership Chair of Caltech’s Division of Engineering and Applied Science. “It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world.”

Transitioning away from fossil fuels.

The cost of turning sunlight into electricity has fallen more than 90 percent over the last decade. Solar is now the cheapest form of newly built energy generation. Job done? Not quite. Right now, solar works well at cost-competitive prices and can help us cut emissions significantly. But with less than five percent of the world’s electricity delivered by solar, we are just at the start.

The solar panels of 2022 are like the chunky mobile phones of the 1990s. Much more is possible with the same underlying technology.

“We are very pleased that we can now start with the first activities to stimulate and consolidate cellular agriculture in the Netherlands,” said Ira van Eelen, CEO of KindEart. Tech and a board member of Cellular Agriculture Netherlands. “With this we can guarantee that the Netherlands remains the ideal place for cellular agriculture to thrive. We have a rich history in cellular agriculture and are a global leader in biotechnology, alternative proteins and food innovation. Supported by this visionary leadership that the Dutch government is showing again today, we will expand our team in the coming months and roll out the first activities around public research, scaling up, and education.”

Indeed, the Netherlands has been demonstrating considerable progress in developing cultured meat. In July, for example, Dutch company Meatable revealed its first lab-grown sausages, which are expected to go on sale to consumers by 2025. The addition of €60 million in government funding will make the Netherlands an even more attractive location for companies in the sector.

Currently a niche and miniscule part of the overall food market, cultured meat has potential to become another “exponential” technology – much like the semiconductor industry, solar energy, genome sequencing, and so on. The benefits in terms of animal welfare, climate change, food safety, antibiotic resistance, land and water usage could be substantial.

Tandem solar cells made of perovskite and silicon enable significantly higher efficiencies than silicon solar cells alone. Tandem cells from HZB have already achieved several world records. Most recently, in November 2021, HZB research teams achieved a certified efficiency of 29.8% with a tandem cell made of perovskite and silicon. This was an absolute world record that stood unbeaten at the top for eight months. It was not until the summer of 2022 that a Swiss team at EPFL succeeded in surpassing this value.

Three HZB teams worked closely together for the record-breaking tandem cell. Now they present the details in Nature Nanotechnology. The journal also invited them to write a research briefing, in which they summarize their work and give an outlook on future developments.

Wind and solar power are intermittent, generating power when it’s available rather than when it’s needed, so the green energy transition will require huge amounts of energy storage. This could end up taking many forms, from conventional lithium-based “big battery” installations, to flow batteries, silicon phase-change batteries, molten salt batteries, iron-air batteries, gravity batteries, carbon dioxide expansion batteries, and other more unusual ideas like buoyancy batteries.

Each has its own advantages and disadvantages in terms of efficiency, size, location, installation costs, operating costs, input and output power ratings, longevity and how long it can store the energy for. That’s good, since different solutions will fill different needs – some backing up the power grid during instantaneous demand spikes, others smoothing out the mismatched daily curves between demand and renewable supply, and others still helping to address seasonal supply drops, like when solar drops off through the winter.

From pv magazine Australia

Volt Solar Tile, a Leeson Group subsidiary, says its Australian-designed building-integrated photovoltaic (BIPV) roof tile has the highest wattage of any solar tile on the global market, with a maximum power output of 115 W and a solar efficiency of up to 19.3%.

Peter Leeson, managing director of Leeson Group and the director of Volt Solar Tile, said the Volt Planum and Lodge mono PERC solar tiles are the first in the world that can generate the same amount of energy as a standard PV panel.
