We’re in the Wild West when it comes to blockchain technology for the electric grid. But Steve Davis, founder and CEO of Oxygen Initiative, has a vision of where we’re headed — and it’s big.
As India’s summer intensifies, many states are already in the midst of a drought—and the hottest days have yet to arrive. At the same time, water-intensive agriculture, rapid urban expansion, increases in industrial activity and growing energy production are driving the country’s water demand upward. More than half of India is now considered severely water stressed.
Part of the problem is that India still manages its water as an infinite resource on a linear model of withdrawal, consumption and disposal. But a more efficient management model is to look at water from a “circular economy” perspective. Water’s usability doesn’t need to end once it washes down the drain. Rather, we can see industrial and domestic wastewater as a valuable resource from which usable water, nutrients and even renewable energy can be extracted.
How do we compensate those who add clean electricity to our shared power grid? This fundamental question has affected the rate at which the U.S. has adopted, deployed, and put into use clean, distributed energy resources.
Canadian firm is hoping to cash in on the burgeoning market for electricity storage -- no matter which technology breaks out first.
NRStor Inc. is positioning itself to be the go-to distributor, developer and operator of lithium-ion batteries, magnetically-levitated flywheels and other technologies seeking to solve the age-old question of how to save electricity for later use. The Toronto-based company is the only distributor of Tesla’s Powerwall residential battery in Canada and is working to turn a giant salt cavern into a compressed air energy storage system.
Battery technology is advancing swiftly, largely driven by Elon Musk’s Tesla Inc. At the same time, other methods are being refined that can be used to store energy for even longer periods of time. The global market could expand to around $20 billion by 2024, from around $600 million in 2015, according to U.S. firm Navigant Research.
Imagine a future when solar cells can be sprayed or printed onto the windows of skyscrapers or atop sports utility vehicles -- and at prices potentially far cheaper than today’s silicon-based panels.
It’s not as far-fetched it seems. Solar researchers and company executives think there’s a good chance the economics of the $42 billion industry will soon be disrupted by something called perovskites, a range of materials that can be used to harvest light when turned into a crystalline structure.
The hope is that perovskites, which can be mixed into liquid solutions and deposited on a range of surfaces, could play a crucial role in the expansion of solar energy applications with cells as efficient as those currently made with silicon. One British company aims to have a thin-film perovskite solar cell commercially available by the end of 2018.
Big oil is starting to challenge the biggest utilities in the race to erect wind turbines at sea.
Royal Dutch Shell Plc, Statoil ASA and Eni SpA are moving into multi-billion-dollar offshore wind farms in the North Sea and beyond. They’re starting to score victories against leading power suppliers including Dong Energy A/S and Vattenfall AB in competitive auctions for power purchase contracts, which have developed a specialty in anchoring massive turbines on the seabed.
The oil companies have many reasons to move into the industry. They’ve spent decades building oil projects offshore, and that business is winding down in some areas where older fields have drained. Returns from wind farms are predictable and underpinned by government-regulated electricity prices. And fossil fuel executives want to get a piece of the clean-energy business as forecasts emerge that renewables will eat into their market.
No country will ever get to 100 percent renewable energy without using geothermal, biomass, hydropower or a combination of the three. These technologies are able to provide energy around the clock, (baseload) and do not depend on the sun shining or the wind blowing.
The user selection board of the €11 million (US$11.8 million) Funding Ocean Renewable Energy through Strategic European Action (FORESEA) project has awarded “Recommendations for Support” to 15 offshore renewable energy technologies, according to an announcement today from FORESEA.
Finland-based clean energy firm Fortum last week said that it has formed a joint venture with Lietuvos Energija to build a waste-to-energy combined heat and power plant in Kaunas, Lithuania.
The solar industry is one of our most obvious success stories. Our industry directly employs 261,000 people. We generate energy that is both clean and renewable. And we generate this energy at prices that are less than conventional utility power — as low as 6 cents per kwh.
As the power of sensors and processing rise and their costs drop, those of us who study the “greening” of information and communications technology are looking ahead to the challenges posed by artificial intelligence.
Plans to install turbines on platforms that float in the sea are gathering pace as renewable energy developers seek new areas to harvest wind power.
Dubai’s government-owned utility completed a 200-MW power plant one month ahead of schedule as part of a plan to build the world’s largest solar energy park by 2030.
This week, the largest renewable energy project built in the U.S. through an alliance of diverse buyers reached commercial operation. The development of the 60-MW Summit Farms Solar project was driven by demand from the Massachusetts Institute of Technology (MIT), Boston Medical Center, and Post Office Square Redevelopment Corporation.
Historically, lighting was the driver for electricity systems. Edison lit up Manhattan, New York. But now, with solar panels and a variety of LED fixtures, from nightlights to lawn lights, street lamps to traffic lights to ceilings bulbs (if we may call them that), illumination at night, even for the poor, is largely a solved problem.
Traditionally, solar electricity generation has been driven by feed-in tariffs. Each kilowatt-hour of electricity generated by a solar system has been given a fixed high value independent from the time of the day and location.
San Diego Gas and Electric last week said it has launched a 2-MW vanadium redox flow battery storage pilot project in coordination with Sumitomo Electric.
A team of scientists at the University of Cambridge has developed a way of using solar power to generate hydrogen from biomass, the U.K. university said last week.
DesignPro Ltd. and GKinetic Energy Ltd. are collaborating to develop a new range of run-of-river hydrokinetic turbines.
