World's First Solar-Hydrogen Residential Development Is 100% Self-Sustaining

We've seen individual homes that are completely off-grid, but there are very few residential developments that have this distinction. Thailand-based development company CNX Construction is set to debut the world’s first 24-hour, solar-powered hydrogen storage multi-house complex.

The Phi Suea House in Chiang Mai, Thailand utilizes this innovative energy storage technology to power not just one, but four family homes as well as several support buildings with the clean, green energy of the sun.

The genius of this project is that it solves problems inherent with solar panels—they only work when the sun is out and can generate more energy than needed. Although the nascent battery industry solves some of these problems, "they are not well suited for long term use," CNX Construction said.

"Power storage in batteries is also not ideal for huge amounts of energy," the company pointed out. "In general, batteries are expensive, heavy and made from dangerous materials with questionable recycling processes."

In September, EcoWatch wrote about a similar project: a solar-powered hydrogen fuel cell generator that has been set up in Honolulu, Hawaii's port. Hydrogen fuel cells are a hotly debated issue because most projects use natural gas as the power source and it’s still seen as cost-prohibitive on a commercial scale. These respective solar-hydrogen projects, however, offer a clean energy storage alternative.

So how does it work? According to Cityife Chiang Mai, "during the day, solar panels on five of the structures capture energy from the sun and send it to the energy building. The energy building then distributes power to the buildings on the compound while also converting water into hydrogen gas."

CNX Construction explained:

The best way to store energy is to generate hydrogen gas via electrolyzers with solar energy and pure water during the day. Electrolyzers produce hydrogen gas by using an electric current to separate water into its composite gases: hydrogen and oxygen.

During night or when we need additional energy the hydrogen is used to produce power with a fuel cell.

Our energy storage is a hybrid battery-hydrogen system which maximizes the advantages of both the batteries and fuel cell. Batteries take the very fast and short loads, while the massive permanent energy load is supplied by the hydrogen/fuel cell.

The process is 100 percent clean as its only byproducts are oxygen gas and water, the company said. Learn more about the technology in the video below:

“It’s a dream to have 24-hour access to the power of the sun. With our renewable power system and hydrogen energy storage, we have fulfilled this dream,” Sebastian-Justus Schmidt, initiator of the Phi Suea House project, said in a press release.

While the energy storage system is what makes this project unique, many other design considerations make this house "the greenest of green," a CNX Construction representative told EcoWatch.

"A strong motivation in this project is to create a residence that is 100 percent self-reliable," the rep said. "That is done through the production of their own energy, but is also seen in the permaculture, fish pond and rain water-collection system."

The compound will also feature solar hot water panels to heat water, double-glazed windows, thick walls, natural ventilation, efficient fans to reduce air conditioning use and large windows and lower-power LED lamps to minimize the energy required for lighting, Gizmag reported.

Gizmag also noted that a partial excess of the electricity generated by the panels will be stored in two 2,000-Ah lead-acid battery banks.

The project is set for completion by the end of this year. By that time, CNX Construction will have installed 114 kilowatt of photovoltaic panels. The company estimates that with the initial installation, an average of 247 kilowatt hour will be generated every month, or enough to power all four homes and all other equipment and infrastructure, including the water pumps.

The company has not released cost figures for the project, but said, "We have calculated a return on our investment (ROI) based on 5 to 6 Thai Baht/kilowatt hour. The time for a ROI will be around 15 years as of today."

"Due to its widening acceptance, the cost of similar systems will drop within the next 3 to 5 years and will generate a much faster ROI," the release added.

The official opening of the Phi Suea House is set for Jan. 29, 2016.

Advocates Shouldn’t Be Afraid to Tell the Truth About Climate Change

By Jeremy Deaton

It has been a tough few months for climate change. In October, an international body of climate scientists declared humans have a little more than a decade to make the drastic changes needed to keep rising temperatures reasonably in check. In November, federal scientists released an equally grim assessment detailing the unprecedented floods, droughts and wildfires expected to hit the U.S. Then, this month, with the world ablaze, diplomats gathered in Poland to bicker over how much water each country should pour on their respective fires and, in some cases, whether scientists were exaggerating the size of the flames.

The Dirty Scheme to Make Americans Buy More Gasoline

By Rhea Suh

It's not often that an industry chieftain brags to investors about picking the pockets of American families with help from the White House.

That's what happened, though, after Big Oil schemed with the Trump administration last summer to ensure higher gasoline consumption—to the tune of $16 billion a year—and more climate-disrupting carbon pollution from our cars, vans and pickup trucks.

Trump Administration Sued Over Controversial Arctic Drilling Project

Conservation groups are suing the Trump administration to halt construction of a controversial oil production facility in Alaska's Beaufort Sea, the first offshore oil drilling development in federal Arctic waters.

Hilcorp Alaska received the green light from the Interior Department in October to build the Liberty Project, a nine-acre artificial drilling island and 5.6-mile underwater pipeline, which environmentalists warn could risk oil spills in the ecologically sensitive area, threaten Arctic communities and put local wildlife including polar bears at risk.

Indigenous Group Sues Exxon, Energy Majors Over Fracking Waste Contamination in Patagonia

A major indigenous group in the Argentine Patagonia is suing some of world's biggest oil and gas companies over illegal fracking waste dumps that put the "sensitive Patagonian environment," local wildlife and communities at risk, according to Greenpeace.

The Mapuche Confederation of Neuquén filed a lawsuit against Exxon, French company Total and the Argentina-based Pan American Energy (which is partially owned by BP), AFP reported. Provincial authorities and a local fracking waste treatment company called Treater Neuquén S.A. were also named in the suit.

Should Plant-Based Proteins be Called 'Meat'?

By Melissa Kravitz

Fried chicken, bacon cheeseburgers and pepperoni pizza aren't uncommon to see on vegan menus—or even the meat-free freezer section of your local supermarket—but should we be calling these mock meat dishes the same names? A new Missouri law doesn't think so. The state's law, which forbids "misrepresenting a product as meat that is not derived from harvested production livestock or poultry," has led to a contentious ethical, legal and linguistic debate. Four organizations—Tofurky, the Good Food Institute, the American Civil Liberties Union of Missouri and the Animal Legal Defense Fund—are now suing the state on the basis that not only is the law against the U.S. Constitution, but it favors meat producers for unfair market competition.

IEA: China and India to Fuel Further Rise in Global Coal Demand in 2018

By Daisy Dunne

The IEA's Coal 2018 report finds that global coal demand grew by 1 percent in 2017 after two years of decline. The rise was chiefly driven by global economic growth, it says. Despite recent growth, demand is still below "peak" levels seen in 2014.

Demand is likely to "remain stable" until 2023, the report authors say. This is because falling demand in western Europe and North America is likely to be offset by increased demand in a host of Asian countries, including India, Indonesia and Vietnam.

Carbon Brief takes a look at the IEA's changing coal forecasts for key world regions.

81% of Voters Support a Green New Deal, Survey Finds

It's been little over a month since newly-elected Congresswoman Alexandria Ocasio Cortez joined some 200 young climate activists for a sit-in in soon-to-be House Majority Leader Nancy Pelosi's office to demand that Democrats back a Green New Deal, a plan to transform the U.S. energy economy in order to stave off climate change and promote greater equality. Since then, support has ballooned for the revolutionary policy plan, with 38 Congresspeople now pledging to back a select committee to develop it, and to renounce donations from fossil fuel companies, according to the latest tally from the Sunrise Movement. But what do voters think?
