Carbon-Negative Energy Generation

- Adam Clare

All Power Labs sells a device that converts biomass into electric energy. Their machine, which is based on technology over 60 years old, can produce insanely cheap energy while making use of plant matter. They have units that produce 10 kW and 20 kW respectively while the wait for approval for a 100 kW version.

The company even built an experimental unit for a car that ran for quite a distance using only walnut shells. This instantly made me think of the modified Delorean in Back to the Future.

All Power Labs makes machines that use an ancient process called gasification to turn out not only carbon-neutral energy, but also a carbon-rich charcoal by-product that just happens to be a fertilizer so efficient that Tom Price, the company’s director of strategic initiatives, calls it “plant crack.”

Gasification, in which dense biomass smoldering — but not combusting — in a low-oxygen environment is converted to hydrogen gas, is nothing new. Price said that ancient cultures used it to enrich their soils, and during World War II, a million vehicles utilized the technology. But after the war, it more or less vanished from the planet, for reasons unknown. Until Mason needed a way to power his flamethrowers, that is.

All Power Labs has taken gasification and combined it with two of the Bay Area’s most valuable commodities — a rich maker culture and cutting-edge programming skills — to produce what are called PowerPallets. Feed a bunch of walnut shells or wood chips into these $27,000 machines and you get fully clean energy at less than 10 cents a kilowatt hour, a fraction of what other green power sources can cost.

Scotland Starts Europe’s Largest Tidal Wave Energy Installation

- Adam Clare

Tidal wave energy installations are nothing new, but installing it on a scale that can power 42,000 homes is. The other day, the Scottish government gave the go ahead for starting a wave-powered energy installation.

“This is a major step forward for Scotland’s marine renewable energy industry. When fully operational, the 86 megawatt array could generate enough electricity to power the equivalent of 42,000 homes – around 40% of homes in the Highlands. This … is just the first phase for a site that could eventually yield up to 398 megawatts.”

Speaking at the Scottish renewables marine conference, Ewing also announced that developers Aquamarine Power Limited and Pelamis Wave Power are to share a slice of a £13m wave “first array” support programme, part of the Scottish government’s marine renewables commercialisation fund.

Ewing said the tide is turning for the wave sector.

More Policies Support Renewable Energy Around the World

- Adam Clare

More countries than ever before now have policies that support renewable energy production. This is obviously a good thing as we are seeing the impact of climate change (like the recent tornados in Japan). We are now a seeing a global effort to slow climate change via policy over the last couple years with Asian and South American countries enacting polices, previously it was primarily only European nations.

The economic diversity of countries enacting support policies for renewable energy has also greatly expanded. High-income economies accounted for 69 percent of all policy support by mid-2005, but by early 2013 this had declined to 30 percent. The other economic groups each increased their share by more than 10 percent.

“As the renewable energy sector continues to mature, policymakers face a host of new challenges,” said Evan Musolino, trend author. “While the pace of countries adopting new renewable energy support policies has slowed somewhat in recent years, the sector has experienced a flurry of activity centered on revising existing policy mechanisms. Policy changes have been driven by a variety of factors, both positive and negative.”

Rapidly changing market conditions for technologies such as solar photovoltaics, where module costs declined by 80 percent since 2008 and by 20 percent in 2012 alone, have dramatically reduced the level of support needed to make projects attractive to investors and feasible for project developers. Simultaneously, the global economic slowdown left many countries with continuously tight national budgets, which has threatened support for the renewable energy sector. The combination of factors has led to a number of cuts to existing incentive programs.

German Coal and Gas Power Plants Closing Due to Cheap Renewable Energy

- Adam Clare

Germany has been so effective in tranisitioning from unsustianble (econmically and environemntally) energy sources to renewable ones that it is uncompetitive to burn fossil fuels for power!

“Due to the continuing boom in solar energy, many power stations throughout the sector and across Europe are no longer profitable to operate,” RWE said in a statement.

“During the first half of 2013, the conventional power generation division’s operating result fell by almost two-thirds. The massive reduction in power station margins is a major factor in this development.”

On Tuesday, E.On said it had shut down or left idle 6,500 megawatts of generating capacity.

It had previously announced plans to close a total of 11,000 megawatts, but now says it may close more.

New Solar Powered Vehicles Seemingly from the Future

- Adam Clare

Last month an airplane known as Solar Impulse completed a fully solar-powered flight across the USA as a demonstration of current solar solutions. In the video above you can see why they made the flight and how the Switezerland-based company wants to change air travel.

At the Guardian there is an article on the flight plus other up and coming solar powered vehicles that we will hopefully see all over. The faster we reduce our global fossil fuel consumption the faster we can improve our planet and our economy.

Its solar cells are 135 microns thin – the same as a human hair; its motors waste only 6% of the energy they consume, compared with a typical bleed of 70%; its carbon fibre panels that form the structure of the wings and fuselage are, at 25g/m squared, three times lighter than writing paper. The new plane, the HB-SIB, can fly through night and day, clear skies and storms, at a top speed of 70km an hour. “We built the first plane with the technology of 2007,” Piccard says. “We built the second plane with the technology of 2015.”
…
Piccard sums it up: “The goal is to change the mindset of people through Solar Impulse. If a plane can fly around the world with no fuel, nobody can say that we cannot reach incredible goals with clean technology. You have a lot of resistance to change, a lot of people saying, ‘I don’t believe in that’ because of dogma. They are afraid of change and they are not pioneers.
