World’s first zero-emissions fossil-fuel plant expected to go live in 2018

Comments Off on World’s first zero-emissions fossil-fuel plant expected to go live in 2018

North Carolina-based NET Power is pioneering a novel approach to capturing carbon dioxide in its reportedly zero-emissions natural-gas pilot power plant in Houston, Texas . The company is investing $150 million in its innovative design, which is centered around turbine technology that is mostly unchanged since its invention over 150 years ago. The key difference is that NET Power’s turbine uses carbon dioxide , rather than a mixture of hot gases, to transfer heat, which is then converted into mechanical energy and, ultimately, electricity. NET Power hopes that its plant design will prove efficient enough to be mass marketed and installed at natural gas power plants around the world. The turbine technology used in NET Power’s demonstration plant is based on the Allam cycle , named after its creator Rodney Allam, who developed the system in collaboration with colleagues at 8 Rivers , an investment firm focused on innovative technology . “He did it old-school style—with just pen, paper, and a four-function calculator,” said Walker Dimmig, a principal at 8Rivers, according to Quartz . “We had to hire an engineering firm to redraw Rodney’s drawings on the computer, and verify whether what he claimed would be feasible.” The Allam cycle exploits the unusual qualities of carbon dioxide, which, under high pressure and temperature, becomes a “supercritical fluid,” a state of matter that shares characteristics of a liquid and a solid. In its supercritical fluid form, carbon dioxide has proven to be an efficient extractor of heat energy in a turbine .

Because of their highly efficient design, NET Power’s turbines are one-tenth the size of normal turbines. After some final tests are conducted and minor problems are fixed, NET Power expects its plant to begin its operation in 2018. At full capacity, it will produce enough electricity to power 40,000 homes. NET Power plans to license its technology, rather than building its own plants, a practical move in response to a challenging market. However, if the natural gas boom is here to stay, NET Power hopes that its carbon capture technology may prove useful and popular as the world shifts towards a cleaner energy economy.

Affordable new device uses solar energy to produce hydrogen and electricity

Comments Off on Affordable new device uses solar energy to produce hydrogen and electricity

Researchers at the University of California Los Angeles (UCLA) have advanced the field of hydrogen power by creating a hybrid device that uses solar energy to produce hydrogen and electricity in a cost-effective manner. “People need fuel to run their vehicles and electricity to run their devices,” said Richard Kaner, lead author of the study and a UCLA distinguished professor of chemistry and biochemistry. “Now you can make both fuel and electricity with a single device.” The new invention is a significant step forward in the quest to harness the power of hydrogen as a fuel source, particularly in transportation. “Hydrogen is a great fuel for vehicles: It is the cleanest fuel known, it’s cheap and it puts no pollutants into the air — just water ,” said Kaner, “and this could dramatically lower the cost of hydrogen cars.” In addition to positive and negative electrodes typically found in battery systems, the UCLA device includes an electrode with the ability to either store electrical energy or use it as a catalyst for water electrolysis, the process by which hydrogen and oxygen atoms are split from a water compound. To increase the device’s efficiency, the researcher team maximized the surface area upon which water makes contact. This additional surface area then allows greater production of hydrogen as well as increased energy storage. Related: New nanomaterial pulls hydrogen from seawater to power fuel cells Although commercial production of hydrogen has often proven to be costly and carbon intensive , the usage of ever-cheaper and clean solar power could change the game. The materials used in the UCLA device to create hydrogen, such as nickel, iron, and cobalt, are also significantly cheaper and more abundant than precious metals like platinum typically used in the process. Finally, the device, powered by the sun, is designed to be accessible even in isolated areas, thus increasing the viability of hydrogen as a fuel source for vehicles on long trips. Although the current model can be held in the palm of one’s hand, the principles behind the device may be applied at a greater scale. Via New Atlas / UCLA Images via Reed Hutchinson/UCLA

Comments Off on Stunning multi-level bamboo home stands deep in the mountains of Bali

We’ve always loved IBUKU’s beautiful bamboo structures , but their latest project, the Ananda House, is simply stunning. The private home, located in Sibang Gede, Bali, is made up of three multi-level bamboo towers embedded into Bali’s lush green vegetation. The bamboo buildings are designed to exist in harmony with the heavily-forested landscape – and they protect the surrounding vegetation as much as possible. While constructing the homes’ many balconies, IBUKU cut holes into the roofs’ overhangs in order to make way for the surrounding trees to grow. Related: Explore This Incredible Green Village in Bali Made Entirely From Bamboo A winding stone path bordered by terraced gardens leads to the entrance of each structure. The pavilion to the right houses the family room, which is a large space with an open-air terrace. At the heart of the living area is the kitchen, complete with a curving countertop made from slabs of locally-sourced river stone . The bedrooms are perched over the living space and designed to take advantage of natural light and ventilation. Each room has an east-facing private balcony that provides incredible views over the valley. To the back of the main building is a grotto pool whose design mimics the natural landscape, creating a fun, indoor-outdoor space. The master bedroom is located at the highest point of the structure. It’s a stunningly romantic space with a lookout tower at the top. The sleeping area is located on the first level, and an attached outdoor bathroom , complete with a monolithic bathtub, looks out over the valley. + IBUKU Via Archdaily

Comments Off on More than 20 organizations launch Solar Saves Lives to electrify Puerto Rico

Puerto Rico’s electricity crisis continues – and the solar industry plans to help. More than 20 organizations and companies, including The Solar Foundation , Sunrun , and the Clinton Foundation , launched the Solar Saves Lives initiative to bring solar technology to American citizens in Puerto Rico and the United States Virgin Islands (USVI) after the recent hurricanes . Their priorities are two food markets in San Juan and 62 rural medical clinics. Puerto Rico’s loss of power doesn’t just mean people sit in the dark. It also means it can be harder to obtain fresh water or food. Many rural medical clinics are still closed, meaning it can be difficult for people to receive medical attention they need. Several organizations and companies are responding with over $5 million in solar equipment commitments to work towards restoring power in Puerto Rico and the USVI and helping the islands be more resilient to future storms. Related: Richard Branson is planning to rebuild the Caribbean with clean energy Former president Bill Clinton said in a statement, “Seven weeks after Hurricane Maria made landfall in the Caribbean, people in Puerto Rico and the U.S. Virgin Islands are still in urgent need of assistance. The solar equipment donated through this effort will save lives by aiding recovery efforts, providing power for people in remote areas, and solarizing critically needed services like refrigeration and medical care.” Direct Relief, Operation Blessing, J/P Haitian Relief Organization, SunSpec Alliance, BayWa r.e. Solar Systems, Prana Power, CAM Solar, Campervan HQ, Carolina Solar Energy, Renogy, and Solight Design are among the companies and organizations involved. Solar Saves Lives will be bringing equipment like lanterns, cell chargers, solar refrigeration units, solar water purification units, battery packs, solar panels, and inverters to impacted areas. Solar Saves Lives is asking for both product and monetary donations; find out how to help here . + Solar Saves Lives Images via Solar Saves Lives and Wikimedia Commons

Comments Off on Plantagon’s crowdfunded plantscraper aims to produce 500 metric tons of food a year

Swedish company Plantagon believes that ‘plantscrapers’ are the way of the future—and part of solution to the global food crisis. Part urban farm, part skyscraper, these vertical greenhouses could provide large-scale organic food production in cities, with a much smaller energy and carbon footprint than industrial agriculture. After years of research and development, Plantagon is now ready to embark on their first landmark plantscraper, called The World Food Building, and is crowdfunding their way to success . A pioneer in the fields of urban agriculture and food technology, Plantagon has set their sights on solving the food crisis as cities grow larger and arable land shrinks. Thus, the company created The World Food Building, a 60-meter-tall vertical farm and 16-story office building proposed for Linköping, Sweden that, if built, would serve as an international model for vertical industrial urban farming. The innovative ‘plantscraper’ would use Plantagon’s patented technology to produce 500 metric tons of organic food annually in a closed, clean, and climate-controlled environment. At least half of the energy used in food production would be recaptured and reused as floor heat in the office building. Plantagon estimates that The World Food Building could save 1,000 metric tons of carbon dioxide emissions and 50 million liters of water as compared to traditional industrial farming systems. To turn their first plantscraper into reality, Plantagon has turned to crowdfunding and asked the community to join them as allies. “We are reaching out to people everywhere who feel that commercial organizations should also be the driving force of change,” said Hans Hassle, Plantagon’s Co-founder and Secretary-General. “People are sick and tired of businesses being shortsighted and just-for-profit driven. We believe it’s time for this to change and the time for ‘business as usual’ is over. With potentially 100,000 allies all over the world supporting Plantagon, we will show that the power of the crowd gets the job done.” + Plantagon
