The booster station for China’s first large-scale, pile-fixed deep-water offshore PV project has been energized for the first time.

‘China’s first large-scale offshore PV project’ ready for operation

,

The CGN Yantai Zhaoyuan 400 MW floating solar project, located in Laizhou Bay in northern Zhaoyuan City, spans 6,44 square kilometers and comprises 121 PV sub-arrays.

With an alternating current (AC) side-rated capacity of 400 MW and a direct current (DC) side installation capacity of 539.3274 MW, the project uses Grand Sunergy’s Seapower double-sided, double-glass heterojunction (HJT) solar modules.

According to the company, offshore photovoltaics face unique challenges due to the harsh marine environment, which includes high humidity, salt spray, corrosion, UV radiation, lightning, low temperatures, and biological fouling.

A recent review article comprehensively explored how solar concentrators can enhance the efficiency of photocatalytic wastewater treatment.

Solar concentrators improve photocatalytic wastewater treatment efficiency

A recent review article published in the journal Energies comprehensively explored how solar concentrators can enhance the efficiency of photocatalytic wastewater treatment. The researchers examined the fundamentals of solar concentration and its ability to significantly improve photocatalytic processes.

Background

Water pollution has increased due to industrialization and urbanization, with agricultural runoff, untreated sewage, and toxic industrial discharges being major contributors. Conventional wastewater treatment methods can create secondary pollution or require high energy, making them costly. In this context, photocatalysis has emerged as a sustainable and eco-friendly solution, utilizing solar energy to degrade and remove various types of organic and inorganic pollutants in the water.

Maldives has issued an invitation to tender for the installation of 10 MWp grid-connected floating solar PV systems in Addu city.

Maldives tenders 10 MW of floating photovoltaics (PV) in Addu city

The Government of the Republic of Maldives, with funding from the World Bank, has issued an invitation to tender for the installation of 10 MWp grid-connected floating solar photovoltaic systems in Addu city. This project is part of the Accelerating Renewable Energy Integration and Sustainable Energy (ARISE) initiative, which aims to improve the country’s renewable energy capabilities.

The Ministry of Finance, on behalf of the Ministry of Climate Change, Environment and Energy, is seeking bids for two specific lots under the Design, Build, Financing, Own, Operate and Transfer (DBFOOT) modality. Lot 1 involves the installation of 2 MWp grid-connected floating solar PV systems at Maradhoo Port and Hulhumeedhoo Central Port. Lot 2 covers the installation of 8 MWp grid-connected floating solar PV systems in the Hithadhoo port area.

A Purdue University team optimized corn yields in solar-powered fields by managing dynamic shadows cast by solar arrays throughout the day.

Validated simulations optimize solar power generation with row-crop agriculture

A Purdue University research team has demonstrated how to optimize yield in corn fields equipped with solar power arrays that throughout the day cast dynamic shadows across growing crops.

The team of eight researchers from Purdue University and Aarhus University in Denmark published their findings July 26, 2024, in Cell Reports Sustainability.

Solar panel arrays—photovoltaics—normally cast permanent shadows on the ground throughout the day. Permanent shadow on a farm field would harm crop growth. The Purdue team tested an agrivoltaics system that towers high above the crops to permit combine harvester operations.

Check out the ‘world’s first’ DC-to-DC solar-powered EV charger

California-based Enteligent is accepting pre-orders for what it claims is the world’s first DC-to-DC solar-powered EV charger.

August 21, 2024 update: Enteligent has raised $6 million in capital from investors to scale the commercialization of its DC-to-DC solar-powered EV chargers. Taronga Ventures led the funding round. This latest funding round brings the company’s total fundraising to $19 million since 2021.

The company also announced that it’s supplying a long-dwell-time 25kW DC-to-DC EV charger to a large logistics company to power its newly electrified delivery fleet.

For the first time, it appears that solar and wind renewables will produce more energy in the US than coal for the year.

Renewables producing more energy than coal in the US for the first time

Predictions that wind and solar energy in the US would eventually overtake coal in terms of how much energy is produced in a year appear to have finally come true. For the first time, it appears that solar and wind renewables will produce more energy in the US than coal for the year.

Typically over the last few years, solar and wind have represented the most energy production early in the year, with coal overtaking when demand ramps up in the summer months. For 2024, that didn’t happen. Instead, solar energy ramped up 36% from the previous year, generating 118 terawatt-hours from January to July, and wind production increased 8% over the same time period, generating 275 TWh. Together, solar and wind represent 16% of the nations’s energy production.

The Energy Information Administration expects power plant developers and owners will add 62.8 GW this year in the United States

EIA expects 62.8 GW to come online in 2024, led by solar, energy storage

The Energy Information Administration expects power plant developers and owners will add 62.8 GW this year in the United States, up 55% from 2023 when 40.4 GW came online, the agency said Monday.

Developers and power plant owners brought 20.2 GW online in the first six months this year, adding 3.6 GW, or 21%, more than in the same period last year, the EIA said. The agency expects another 42.6 GW will be added in the second half this year.

About 12 GW of utility-scale solar came online in the first half, accounting for 59% of all new capacity, according to the EIA. Texas and Florida made up 38% of U.S. solar additions, the agency said.

The LGP option will be the 1st state-wide implementation of emerging “flexible interconnection” innovations for distribution system resources

California pioneers new ways to ease interconnection of large DERs

Efforts are accelerating to address the obstacles to interconnecting large distribution system resources like community solar and big box store rooftop solar arrays, advocates of recent reforms report.

Distribution system-connected resources, especially those in the 1 MW to 5 MW range, can offer flexibility to meet electricity demand spikes without requiring significant power system upgrades, the advocates said. But costs to increase system carrying capacity under current interconnection practices make many projects that require system upgrades uneconomic, they added.

A community garden in National City will benefit by receiving a portion of $1.2M from the annual Community Clean Energy Grant awards program.

A solar and battery project will grow next to a garden in National City

A community garden in National City is one of 16 organizations that will benefit by receiving a portion of $1.2 million from the annual Community Clean Energy Grant awards program.

The Olivewood Gardens and Learning Center will use $100,000 it received from San Diego Community Power and Calpine Energy Solutions to install solar panels and a battery energy storage system.

Jen Nation, executive director of the eight-acre greenspace and its nearby office that serves about 10,000 people annually, said the solar and storage project is expected to save the center about $400,000 in energy costs over the course of 20 years.

Premier Resource Management LLC is transforming a 560-acre former oil reservoir in the San Joaquin Valley into a geothermal power plant that also stores renewable energy

Turning California’s oil fields into energy storage sites

Part of the solution to California’s ambitious decarbonization goals may, ironically enough, be found in the state’s oil patch.

On a 560-acre plot of land in a dusty portion of the San Joaquin Valley, Premier Resource Management LLC has partnered with some of the nation’s top energy laboratories on a pilot program to take an abandoned oil reservoir and convert it to a geothermal power plant that can also store renewable energy underground for weeks at a time, instead of just a few hours.

The electricity at the site could flow to an already existing substation nearby, with the megawatts then dispersed into California’s power grid.
