While NASA has made a name for itself by exploring the potentials of life outside our planet, its new Sustainability Base building embraces and respects Earth’s natural resources. Officially deemed, ‘The Greenest Federal Building’, the new eco-structure was awarded the U.S. Green Building Council’s Leadership in Energy and Environmental Design’s (LEED) prestigious Platinum status, which is the highest possible rating awarded by the rigorous program.

The 50,000 square foot, two story office building cost NASA approximately $25 million dollars to build, and integrates natural sunlight into the employee’s working environment through the use of skylights and open windows. Building controls react to slight fluctuations in weather, light, and occupancy, which enables the building to regulate its energy consumption based on immediate need rather than blanket approximations.

Another revolutionary aspect of the building is that it does not have air conditioning. Instead, the building design incorporated air vents in the flooring, which captures the cool night air, and distributing it during the day.

The building is so efficient, it actually generates more electricity than it consumes, due in large part to onsite solar panels, fuel cells and a small wind turbine. The building also incorporates geo-thermo well field water, which circulates through the building through ceiling coils in order to heat or cool the building.

Very limited material was needed during construction due to a lightweight insulated metal panel cladding, and the infrastructure was made of steel instead of concrete because of steel’s flexibility in rebuilding -- should damage from a natural disaster occur.

NASA also incorporated some of its own technologies into the building, including a Bloom Energy Box fuel cell, and a duplicate of the International Space Station’s water recovery system.

While the building is visually stunning, it is also a monument honoring the future potential of green buildings. It proves that engineering is the key to gleaning the most bang for our resource buck, and with NASA leading the way, the future of sustainability is looking greener than ever.

Major move forward for UK’s nascent marine energy sector

The UK’s nascent marine energy sector starts exporting electricity to the grid as the most powerful tidal turbine in the world begins to generate power

Although the industry is small and the technologies are limited, marine-based energy systems look to be taking off as “the world’s most powerful tidal turbine” begins grid-connected power generation at the European Marine Energy Centre

At around 74 metres long, the turbine single-handedly holds the potential to supply the annual electricity demand to approximately 2,000 homes within the UK and offset 2,200 tonnes of CO2 per year.

Orbital Marine Power, a privately held Scottish-based company, announced the turbine is set to operate for around 15 years in the waters surrounding Orkney, Scotland, where the 2-megawatt O2 turbine weighing around 680 metric tons will be linked to a local on-land electricity network via a subsea cable. 

How optimistic is the outlook for the UK’s turbine bid?

Described as a “major milestone for O2” by CEO of Orbital Marine Power Andrew Scott, the turbine will also supply additional power to generate ‘green hydrogen’ through the use of a land-based electrolyser in the hopes it will demonstrate the “decarbonisation of wider energy requirements.” 

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” says Scott in a statement. 

The Scottish Government has awarded £3.4 million through the Saltire Tidal Energy Challenge Fund to support the project’s construction, while public lenders also contributed to the financial requirements of the tidal turbine through the ethical investment platform Abundance Investment.

“The deployment of Orbital Marine Power’s O2, the world’s most powerful tidal turbine, is a proud moment for Scotland and a significant milestone in our journey to net zero,” says Michael Matheson, the Cabinet Secretary for Net-Zero, Energy and Transport for the Scottish Government. 

“With our abundant natural resources, expertise and ambition, Scotland is ideally placed to harness the enormous global market for marine energy whilst helping deliver a net-zero economy.

“That’s why the Scottish Government has consistently supported the marine energy sector for over 10 years.”

However, Orbital Marine CEO Scott believes there’s potential to commercialise the technology being used in the project with the prospect of working towards more efficient and advanced marine energy projects in the future. 

We believe pioneering our vision in the UK can deliver on a broad spectrum of political initiatives across net-zero, levelling up and building back better at the same time as demonstrating global leadership in the area of low carbon innovation that is essential to creating a more sustainable future for the generations to come.” 

The UK’s growing marine energy endeavours

This latest tidal turbine project isn’t a first for marine energy in the UK. The Port of London Authority permitted the River Thames to become a temporary home for trials into tidal energy technology and, more recently, a research project spanning the course of a year is set to focus on the potential tidal, wave, and floating wind technology holds for the future efficiency of renewable energy. The research is due to take place off of the Southwest coast of England on the Isles of Scilly
